Weksler N Klein M Szendro G Rozentsveig V Schily M Brill S Tarnopolski A Ovadia L Gurman GM The dilemma of immediate preoperative hypertension to treat and operate or to postpone
surgery J Clin Anesth 2003 15 179-83
bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment
Howell SJ Sear YM Yeates D Goldacre M Sear JW Foeumlx P Hypertension admission blood pressure and perioperative
cardiovascular risk Anaesthesia 1996511000-1004
bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

Fattori che determinano il rischio cardiaco periop
bull Marcatori clinici
bull Capacitagrave funzionale
bull Intervento chirurgico
bull The overriding theme of this document is that intervention is rarely necessary to simply lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context
bull The purpose of preoperative evaluation is not to give medical clearance but rather to perform an evaluation of the patientrsquos current medical status make recommendations concerning the evaluation management and risk of cardiac problems over the entire perioperative period and provide a clinical risk profile that the patient primary physician and nonphysician caregivers anesthesiologist and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes
bull No test should be performed unless it is likely to influence patient treatment
bull The goal of the consultation is the optimal care of the patient

Dipiridamolo tallio
bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

Indicazioni ai beta bloccanti bull i betabloccanti devono essere continuati nel periop per coloro che li assumono
per indicazione di anginaaritmie sitomaticheipertensione o altre indicazioni delle linee guida ACCAHA di classe I
bull i betabloccanti devono essere somministrati ai candidati a chirurgia vascolare ad alto rischio cardiaco che presentino ischemia agli esami preop (Livello di evidenza B)
bull I beta bloccanti sono poi probabilmente indicati per i candidati a chirurgia vascolare nei quali la valutazione preop identifichi coronaropatia eo un elevato rischio cardiaco definito come la presenza di piugrave di 1 fattore di rischio clinico anche se vanno incontro a chirurgia classificata come rischio intermedio
bull lrsquoutilitagrave dei betabloccanti rimane incerta in pazienti candidati a chirurgia di rischio intermedio o vascolare con un solo fattore di rischio clinico(Livello di evidenza C)e per i candidati a chir vascolare senza fattori di rischio e che non stanno assumendo i farmaci( Livello di evidenza B)
bull Ovviamente i betabloccanti non devono essere somministrati a coloro che presentano controindicazioni assolute al loro impiego
bull In conclusione dosaggi terapeutici di betabloccanti devono essere utilizzati in pazienti ad alto-intermedio rischio cardiaco

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

surgery J Clin Anesth 2003 15 179-83
bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Weksler N Klein M Szendro G Rozentsveig V Schily M Brill S Tarnopolski A Ovadia L Gurman GM The dilemma of immediate preoperative hypertension to treat and operate or to postpone
surgery J Clin Anesth 2003 15 179-83
bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment
Howell SJ Sear YM Yeates D Goldacre M Sear JW Foeumlx P Hypertension admission blood pressure and perioperative
cardiovascular risk Anaesthesia 1996511000-1004
bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

bull The purpose of preoperative evaluation is not to give medical clearance but rather to perform an evaluation of the patientrsquos current medical status make recommendations concerning the evaluation management and risk of cardiac problems over the entire perioperative period and provide a clinical risk profile that the patient primary physician and nonphysician caregivers anesthesiologist and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

surgery J Clin Anesth 2003 15 179-83
bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

surgery J Clin Anesth 2003 15 179-83
bull There is a great deal of debate regarding a trigger to delay or cancel a surgical procedure in a patient with poorly or untreated hypertension
bull In the absence of end-organ changes such as renal insufficiency or left ventricular hypertrophy with strain it would seem appropriate to proceed with surgery
bull A randomized trial of treated hypertensive patients without known CAD who presented the morning of surgery with an elevated diastolic blood pressure was unable to demonstrate any difference in outcome between those who were actively treated versus those in whom surgery was delayed
bull In contrast a patient with a markedly elevated blood pressure and the new onset of a headache should have surgery delayed for further evaluation and potential treatment

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull A retrospective case-controlled study which found that a history of hypertension was an important predictor for perioperative cardiac death but not admission blood pressure
bull The study implies that end-organ damage resulting from hypertension is the likely villain in this group of patients
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint
bull Importance of Surgical Procedurebull The surgical procedure influences the extent of the preoperative
evaluation required by determining the potential range of changes in perioperative management There is little hard data to define the surgery specific incidence of complications and the rate may be very institution depedendent Eagle et al published data on the incidence of perioperative myocardial infarction and mortality by procedure for patients enrolled in the coronary artery surgery study (CASS)6 Higher risk procedures for which coronary artery bypass grafting reduced the risk of noncardiac surgery compared to medical therapy include major vascular abdominal thoracic and orthopedic surgery Ambulatory procedures denote low risk Vascular surgery represents a unique group of patients in whom there is extensive evidence regarding preoperative testing and perioperative interventions
bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Importance of exercise tolerancebull Exercise tolerance is one of the most important determinants of
perioperative risk and the need for invasive monitoring If a patient can walk a mile without becoming short of breath than the probability of extensive coronary artery disease is small Alternatively if patients become dyspneic associated with chest pain during minimal exertion then the probability of extensive coronary artery disease is high Reilly and colleagues demonstrated that the likelihood of a serious complication occurring was inversely related to the number of blocks that could be walked or flights of stairs that could be climbed7 Exercise tolerance can be assessed with formal treadmill testing or with a questionnaire that assesses activities of daily living

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull The overriding theme of this document is that intervention is rarely necessary to simply lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context
bull The purpose of preoperative evaluation is not to give medical clearance but rather to perform an evaluation of the patientrsquos current medical status make recommendations concerning the evaluation management and risk of cardiac problems over the entire perioperative period and provide a clinical risk profile that the patient primary physician and nonphysician caregivers anesthesiologist and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

J2008 Feb72(2)195-9bull The purpose of this study was to determine whether the N-terminal pro-brain natriuretic peptide
(NT-proBNP) concentration before operation can be used to predict perioperative cardiovascular complications in elderly patients undergoing noncardiac surgery METHODS AND RESULTS The study group comprised 279 patients older than 60 years who were scheduled for elective surgery The plasma NT-proBNP concentration clinical cardiac indices and left ventricular ejection fraction were measured prior to operation The postoperative cardiac outcomes were followed and predictors for postoperative cardiac risk were identified Cardiovascular complications occurred in 25 patients (90) Age the incidence of prior ischemic heart disease or congestive heart failure and the plasma NT-proBNP concentration were significantly higher in patients with perioperative cardiovascular complications than in those without Using receiver operating characteristic analysis to predict perioperative cardiovascular events a cut-off value of 201 pgml was identified as the optimal predictor of perioperative complications showing a sensitivity of 800 and specificity of 811 Multivariate analysis revealed that NT-proBNP gt201 pgml (odds ratio (OR) 76 95 confidence interval (CI) 22-266 p=0003) and revised cardiac index gt or =2 (OR 63 95 CI 17-238 p=0007) were independent predictors for perioperative cardiovascular

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull The overriding theme of this document is that intervention is rarely necessary to simply lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context
bull The purpose of preoperative evaluation is not to give medical clearance but rather to perform an evaluation of the patientrsquos current medical status make recommendations concerning the evaluation management and risk of cardiac problems over the entire perioperative period and provide a clinical risk profile that the patient primary physician and nonphysician caregivers anesthesiologist and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

disease and may be useful in the risk stratification of cardiac patients undergoing noncardiac surgery (NCS) The objective of this study was to examine whether BNP levels predict perioperative events in cardiac patients undergoing NCS METHODS Patients undergoing NCS with at least 1 of the following criteria were included a clinical history of congestive heart failure (CHF) ejection fraction lt40 or severe aortic stenosis All patients underwent echocardiography and measurement of BNP performed using the ADVIA-Centaur BNP assay (Bayer HealthCare) Clinical endpoints were death myocardial infarction or pulmonary congestion requiring intravenous diuretics at 30 days of follow-up RESULTS Forty-four patients were entered into the study 15 patients (34) developed cardiac postoperative complications The mean BNP level was 1366 +- 1420 pgml in patients with events and 167 +- 194 pgml in patients without events indicating a highly significant difference (p lt 0001) The ROC area under the curve was 091 (95 CI 083-099)
with an optimal cutoff of gt165 pgml (100 sensitivity 70 specificity) CONCLUSIONS BNP levels may predict perioperative complications in cardiac patients undergoing NCS and the measurement of BNP should be considered to assess the preo

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

Fleisher Lee A MD ++ Platelet Gene Polymorphisms and Cardiac Risk Assessment in Vascular Surgical Patients Anesthesiology 101(6)1291-1297 December 2004bull Results Sixty-five patients (33) experienced one or more ischemic
endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint

bull the presence of a redistribution defect on dipyridamole thallium imaging in patients undergoing peripheral vascular surgery is predictive of postoperative cardiac events In order to increase the predictive value of the test several strategies have been suggested Lung uptake left ventricular cavity dilation and redistribution defect size have all been shown to be predictive of subsequent morbidity10
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

(NT-proBNP) concentration before operation can be used to predict perioperative cardiovascular complications in elderly patients undergoing noncardiac surgery METHODS AND RESULTS The study group comprised 279 patients older than 60 years who were scheduled for elective surgery The plasma NT-proBNP concentration clinical cardiac indices and left ventricular ejection fraction were measured prior to operation The postoperative cardiac outcomes were followed and predictors for postoperative cardiac risk were identified Cardiovascular complications occurred in 25 patients (90) Age the incidence of prior ischemic heart disease or congestive heart failure and the plasma NT-proBNP concentration were significantly higher in patients with perioperative cardiovascular complications than in those without Using receiver operating characteristic analysis to predict perioperative cardiovascular events a cut-off value of 201 pgml was identified as the optimal predictor of perioperative complications showing a sensitivity of 800 and specificity of 811 Multivariate analysis revealed that NT-proBNP gt201 pgml (odds ratio (OR) 76 95 confidence interval (CI) 22-266 p=0003) and revised cardiac index gt or =2 (OR 63 95 CI 17-238 p=0007) were independent predictors for perioperative cardiovascular

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

endpoints (2 death 5 myocardial infarction 20 troponin+ 22 electrocardiogram+) The Pro33 (adjusted odds ratio [OR] 24 [95 confidence interval 12ndash62]) and Met145 (OR 34 [14ndash93]) genotypes were independent predictors of composite ischemic outcome by multivariate regression as were diabetes mellitus (OR 40 [17ndash125]) abdominal aortic surgery (OR 41 [17ndash144]) and thoracoabdominal aortic surgery (OR 64 [27ndash238]) The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 135 P lt 0001) of an ischemia prediction model The derived risk assessment tool had a receiver operator characteristic curve of 073 (065ndash081) compared with 064 (057ndash074) for a model excluding genetic factors (P = 004) A significant relation between the GPIb[alpha] polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint
Dobutamine stress testbull Dobutamine stress echocardiography has been suggested as the best
preoperative test in several recent meta-analyses11 The appearance of new or worsened regional wall motion abnormalities is considered a positive test The advantage of this test is that it is a dynamic assessment of ventricular function Dobutamine echocardiography has also been studied and was found to have among the best positive and negative predictive values Poldermans et al demonstrated that the group at greatest risk were those who demonstrated regional wall motion abnormalities at low heart rates12 The presence of 5 or more segments of new regional wall motion abnormalities denotes a high risk group who did not benefit from perioperative beta blockade in one trial13 Beattie and colleagues performed a meta-analysis of stress echocardiography versus thallium imaging and demonstrate that stress echocardiography has better negative predicative characteristics11 A moderate-to-large perfusion defect by either test predicted postoperative MI and death

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull OBJECTIVE To investigate the combined beneficial effect of statin and beta-blocker use on perioperative mortality and myocardial infarction (MI) in patients undergoing abdominal aortic aneurysm surgery (AAA) BACKGROUND Patients undergoing elective AAA-surgery identified by clinical risk factors and dobutamine stress echocardiography (DSE) as being at high-risk often have considerable cardiac complication rate despite the use of beta-blockers METHODS We studied 570 patients (mean age 69+-9 years 486 males) who underwent AAA-surgery between 1991 and 2001 at the Erasmus MC Patients were evaluated for clinical risk factors (agegt70 years histories of MI angina diabetes mellitus stroke renal failure heart failure and pulmonary disease) DSE statin and beta-blocker use The main outcome was a composite of perioperative mortality and MI within 30 days of surgery RESULTS Perioperative mortality or MI occurred in 51 (89) patients The incidence of the composite endpoint was significantly lower in statin users compared to nonusers (37 vs 110 crude odds ratio (OR) 031 95 confidence interval (CI) 013-074 p=001) After correcting for other covariates the association between statin use and reduced incidence of the composite endpoint remained unchanged (OR 024 95 CI 010-070 p=001) Beta-blocker use was also associated with a significant reduction in the composite endpoint (OR 024 95 CI 011-054) Patients using a combination of statins and beta-blockers appeared to be at lower risk for the composite endpoint across multiple cardiac risk strata particularly patients with 3 or more risk factors experienced significantly lower perioperative events CONCLUSIONS A combination of statin and beta-blocker use in patients with AAA-surgery is associated with a reduced incidence of perioperative mortality and nonfatal MI particularly in patients at the highest risk

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses

bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

J2008 Feb72(2)195-9bull The purpose of this study was to determine whether the N-terminal pro-brain natriuretic peptide
(NT-proBNP) concentration before operation can be used to predict perioperative cardiovascular complications in elderly patients undergoing noncardiac surgery METHODS AND RESULTS The study group comprised 279 patients older than 60 years who were scheduled for elective surgery The plasma NT-proBNP concentration clinical cardiac indices and left ventricular ejection fraction were measured prior to operation The postoperative cardiac outcomes were followed and predictors for postoperative cardiac risk were identified Cardiovascular complications occurred in 25 patients (90) Age the incidence of prior ischemic heart disease or congestive heart failure and the plasma NT-proBNP concentration were significantly higher in patients with perioperative cardiovascular complications than in those without Using receiver operating characteristic analysis to predict perioperative cardiovascular events a cut-off value of 201 pgml was identified as the optimal predictor of perioperative complications showing a sensitivity of 800 and specificity of 811 Multivariate analysis revealed that NT-proBNP gt201 pgml (odds ratio (OR) 76 95 confidence interval (CI) 22-266 p=0003) and revised cardiac index gt or =2 (OR 63 95 CI 17-238 p=0007) were independent predictors for perioperative cardiovascular

undergoing noncardiac surgery Crit Care Med 2007 Aug35(8)1876-81
bull OBJECTIVE In patients with cardiovascular disease or organ failure elevated plasma concentrations of the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine (ADMA) are associated with an increased risk of future cardiovascular events We aimed to investigate elevated plasma ADMA concentrations as a prospective risk marker for adverse events in patients undergoing noncardiac surgery DESIGN Prospective observational study SETTING Two tertiary care centers PATIENTS Four hundred and two patients scheduled for elective noncardiac surgery INTERVENTIONS None MEASUREMENTS AND MAIN RESULTS Patients were followed for 30 days after surgery for a predefined composite end point (death myocardial infarctionacute coronary syndrome acute heart failure severe arrhythmia embolism or thrombosis) Plasma ADMA concentrations at baseline were determined by high-performance liquid chromatography ADMA was only weakly (-02 lt tau lt 02) correlated with other risk markers and risk scores In univariate logistic regression per 01-micromolL increment in plasma ADMA concentration the odds ratio to experience the primary end point increased by 126 (95 confidence interval 110-145 p = 001) In a multivariate logistic regression model adjusting for age gender current smoking plasma creatinine hypertension diabetes ischemic heart disease highly sensitive C-reactive protein revised cardiac risk index type of surgery high-risk surgery ASA class and study center ADMA was found to be an independent risk marker

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis

bull Our data suggest that perioperative mortality is surprisingly low (lt2) in patients with clinically stable HFmdash regardless of EFmdashundergoing elective noncardiac surgery
bull At 1 year crude mortality rates for patients with HF with reduced EF (135) or with preserved EF (63) were significantly higher than for controls (31) However we found no evidence to suggest that the immediate postoperative period was associated with a significantly higher risk of death than the subsequent months This raises the possibility that the long-term postoperative mortality rate that we observed in the patients with HF particularly those with low EF represents the background mortality expected in patients with chronic illnesses
bull Our findings contrast with previous studies that have focused on the perioperative outcomes of patients with HF

bull Abstractbull Background Current perioperative cardiac risk assessment tools use historic
and surgical factors to stratify patient risk Polymorphisms in platelet glycoprotein (GP) IIIa and GPIb[alpha] are associated with myocardial ischemic risk in nonsurgical settings but their relation to perioperative ischemia is unclear The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors
bull Methods One hundred ninety-six patients who underwent infrainguinal abdominal aortic or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIb[alpha] Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis
