CORONARY ARTERY CORONARY ARTERY DISEASEDISEASE
Coronary Artery DiseaseCoronary Artery DiseaseAtherosclerosis◦ An active process by which blockages develop in
heart arteries due to the build up of plaques (cholesterol, platelets, inflammatory cells)
Clinical presentation varies◦ Asymptomatic◦ Chest pain◦ Shortness of breathGoal of treatment is to slow the development of significant blockages
Clinical PresentationClinical Presentation
AsymptomaticAngina = chest pain◦ Stable-occurs with exertion◦ Unstable-occurs at rest
“Heart Attack”= Myocardial Infarction◦ Heart muscle cells die due to lack of oxygen◦ Different types
Risk FactorsRisk Factors
AgeGenderHigh Blood Pressure◦ Systolic (Top number)
Treated versus untreated
SmokingCholesterol◦ Total cholesterol◦ HDL (good) cholesterol
WhatWhat’’s your risk?s your risk?
Framingham Data Risk Calculator10 year risk of “hard cardiac event”◦ Myocardial Infarction (i.e., heart attack)◦ Death due to coronary disease
Patients without known coronary diseaseCoronary artery disease equivalents◦ Diabetes◦ Peripheral Vascular Disease
How is risk calculated?How is risk calculated?
Framingham dataPoints assigned for each risk factor and points summedTotal number of points then correlates to a percentage◦ Percentage is risk of cardiovascular event
over 10 years

Limit sodium to 2400 mg/dayLimit cholesterol to 300 mg/day◦ 200 mg/day if high LDL

ExerciseExercise30 minutes of moderate exercise 4-6 days per weekLight Exercise◦ Desk work◦ Golf◦ Light housework
Moderate Exercise◦ Walking (exercise)◦ Gardening/yard work/farming◦ Cycling◦ Tennis◦ Running◦ Dancing
Heavy Exercise◦ Walking uphill◦ Construction work/physical labor◦ Basketball◦ Football
TreatmentTreatment

VALVULAR HEART VALVULAR HEART DISEASEDISEASE
Calcific (Degenerative) Aortic Valve Calcific (Degenerative) Aortic Valve DiseaseDisease
As valves age, the process of atherosclerosis can affect aortic valve resulting in calcium deposition May result in stenosis or regurgitationSymptoms present in 70-80’sAccelerated in patients with abnormal valves (i.e., bicuspid valves)
HIGH BLOOD HIGH BLOOD PRESSUREPRESSURE
High Blood Pressure High Blood Pressure
“The Silent Killer”Long-standing, untreated high blood pressure damages arteries and veinsLong-term consequences◦ Heart failure◦ Heart attacks◦ Stroke◦ Kidney Failure◦ Blindness
Diagnosis of High Blood PressureDiagnosis of High Blood Pressure
2 or more elevated blood pressures on 2 separate occasions
Metabolic SyndromeMetabolic SyndromeGroup of risk factors which greatly increase risk of developing cardiovascular disease including stroke.Risk Factors◦ Abdominal obesity (abdominal waist
circumference)Men >40 inchesWomen >35 inches
◦ High fasting glucose (>100)◦ High triglycerides (>150)◦ Low HDL (Men<40, Women<50)◦ High blood pressure (>130/85)
RHEUMATIC HEART RHEUMATIC HEART DISEASEDISEASE
Rheumatic Heart DiseaseRheumatic Heart Disease
Begins with “strep throat”Inflammatory process in response to initial infection results in antibodies that attack the connective tissues of the body Approximately 2-4 weeks after initial strep infection, patients present with clinical features of rheumatic fever
Clinical Features of Rheumatic Clinical Features of Rheumatic FeverFever
Pain and swelling in large jointsFeverWeaknessMuscle achesShortness of breathChest painNausea and vomitingHacking coughCircular rashLumps under the skinAbnormal, sudden movements of arms and legsDamage to heart valves may present later and is permanent
Rheumatic Heart DiseaseRheumatic Heart DiseaseEarly recognition and treatment of strep throat has led to a significant decrease in the incidence of rheumatic heart disease in the US and other developed countriesRemains a significant cause of heart disease in developing countriesSymptoms of heart disease may not present until several years after initial Strep infection
TreatmentTreatment
Penicillin to avoid recurrent strep infectionsIf severe valvular disease, require valve replacement
KAWASKIKAWASKI’’S DISEASES DISEASE
KawaskiKawaski’’s Diseases DiseaseInflammation of the small and medium-sized vessels in the body◦ Includes coronary arteriesPresents in early childhood ◦ Ages 2-8Clinical presentation◦ Fever > 5 days◦ Rash◦ Peeling of skin on hands and feet◦ “Pink eye”◦ “Strawberry tongue
TreatmentTreatment
Treatment is designed to stop inflammatory process and prevent long-term sequelae of coronary artery aneurysms.Long-term consequence of Kawaski’s is coronary artery aneuryms which may initially be asymptomatic; however aneurysms may lead to heart attacks later in life.
