Faced with a grandparent, really any older adult, complaining of chest pain, the emergencypediatrician is not required to have an in-depth knowledge of adult internal medicine toeffectively perform an initial evaluation and commence investigation and treatment. Theapproach to these patients requires the recognition of chest pain as a potential hallmark of alife-threatening illness, including myocardial infarction. A standardized approach to anyadult with chest pain should include the efficient delivery of basic diagnostic and therapeuticinterventions that should be available even in a specialized pediatric institution. Timelytransfer to an adult facility to complete the assessment and to exclude life-threateningcauses is essential to maximize the outcome of these patients.Clin Ped Emerg Med 6:222-228 ª 2005 Elsevier Inc.

Accompanying a sick or injured child to the Emer-gency Department (ED) can be upsetting and
stressful for any caregiver. In these circumstances, agrandparent may complain of symptoms that are new orare related to a known illness. Chest pain is one suchsymptom and may result from disease in a variety of bodysystems. In addition, pain severity does not necessarilyreflect the seriousness of the underlying disease process.
A grandparent with chest pain presents a challenge tothe emergency pediatrician who may not have greatexperience or confidence in caring for ill adults and whomay not have immediate access to a specialist in adultemergency medicine or internal medicine. The increasingincidence of teenage pregnancies in recent decades meansthat bgrandparentsQ may not always be elderly. The rangeof potential causes of chest pain to consider in thedifferential diagnosis is, therefore, much greater. Even inthe finest adult treatment facility, the cause of chest painmay not always be quickly determined in the ED.
Etiology of Chest Pain in theGrandparentAs in children, chest pain in adults ranges in se-
riousness from innocent to life-threatening. Chest pain

accounts for 5% of adult ED visits and is therefore a
more common presenting complaint in that population
compared with children. Faced with a grandparentcomplaining of chest pain, the emergency pediatrician
must assume that the cause is life-threatening until
proved otherwise, and arrange to transfer the patient to
an adult facility for further assessment at the earliest
opportunity. Common causes of chest pain, both life-
threatening and non–life-threatening, are shown in
Table 1. The most critical causes of adult chest pain
that should be considered by the emergency pediatri-cian follow below.

presentation suggestive of acute myocardial ischemia

and encompasses myocardial infarction and unstable
angina. It is the commonest life-threatening cause of
acute chest pain presenting to the ED. The diagnosis ofACS is based on symptoms including the nature and
site of the chest pain, risk factors, electrocardiogram
(ECG) findings, and biochemical markers such as
troponin. Table 2 demonstrates that the nature of
acute chest pain and associated risk factors may be

unhelpful in distinguishing ACS from other life threat-
ening causes.
Approximately, 2 million people are admitted to the
hospital in the United States each year for evaluation of
acute chest pain. Of these, about 30% are diagnosed as
having unstable angina or a myocardial infarction.
Myocardial infarction is the leading cause of death inadults in the United States. Up to 8% of patients
presenting with a myocardial infarction are inappropri-
ately discharged from EDs, and the mortality in this
group is approximately double that of patients who are
admitted [1].
Myocardial Infarction
This is a common cause of adult chest pain. One in 6 adult
patients with chest pain has a myocardial infarction, and
the risk is higher in elderly patients [2]. The emergency
pediatrician does not need to be an expert in ECG
interpretation to pursue this diagnosis. Up to 50% of
patients with a myocardial infarction do not have
diagnostic changes on the initial ECG; thus, distinguish-
ing between a diagnosis of unstable angina and amyocardial infarction is difficult. Serial ECGs over sev-
eral hours may show the evolution of ST-segment
changes diagnostic of myocardial infarction. The pres-
ence of ST-segment changes, including ST elevation
greater than 1 mm in 2 leads (Figure 1), mandates rapid
transfer to an adult facility for early fibrinolytic therapy,
ideally within 6 hours of the onset of pain. Similarly, left
bundle-branch block (Figure 2) may be new and resultfrom myocardial infarction.
Unstable Angina
The likelihood of myocardial infarction and death is
increased by the development of unstable angina. This

Managing the grandparent with chest pain 225
Aortic DissectionThis most commonly occurs in the thoracic aorta, withblood dissecting between the vessel intima and media,
generally as a result of an intimal tear. It is initially
misdiagnosed in up to 40% of cases and is diagnosed at
postmortem in up to one third. In-hospital mortality is
approximately 30%. There are no clinical features that
accurately distinguish aortic dissection from ACS.
The diagnosis should always be considered in the
presence of acute chest pain, which may be associatedwith back pain. The pain may be out of proportion to
other clinical findings and require large amounts of
analgesia. Hypertension may be present, and the systolic
blood pressure may be significantly higher in the left arm
than in the right if the dissection extends into the origin
of the brachiocephalic trunk. The ECG, which usually is
normal or shows nonspecific changes, is often not helpful
in making this diagnosis.
Pulmonary EmbolismIn 90% of cases, the source of a pulmonary embolism
(PE) is a deep vein thrombosis in a lower limb. Risk
factors include recent injury or surgery, immobility,
malignancy, hypercoagulability, and a history of throm-
boembolism. For untreated PE, the mortality is approx-
imately 30%.
No specific symptoms or signs are diagnostic of a PE,and the ECG is not helpful in 85% of cases. In a minority of
patients, the ECG may show an S wave in lead I (SI), a Q
wave in lead III (Qa), a T wave in lead III (Ta) (Figure 3),
or a right bundle-branch block (Figure 4). The clinical
presentation of PE ranges from mild dyspnea, with or
without chest pain, to cardiovascular collapse. The
diagnosis should be considered in any grandparent with
pleuritic chest pain, dyspnea, and tachypnea. The goldstandard for diagnosis is pulmonary angiography or axial
computerized tomography of the pulmonary arteries [3,4].
PericarditisInfectious causes of pericarditis include viruses, bacteria,
mycobacteria, and fungi. Inflammation of the pericardium
can occur during a viral illness or, afterward, as a result of
an autoimmune response to the viral illness. Sometimes,
pericarditis occurs in the presence of HIV infection.
Symptoms of pericarditis may include chest pain, dysp-
nea, and fever. The chest pain may be positional and may
worsen with inspiration. Electrocardiogram changes
include depression of the PR segment and elevation of
the ST segment in all leads except aVR and V1, where
reciprocal changes are seen (Figure 5).
Tension PneumothoraxThis can occur in a grandparent who puts their grand-
child’s clinical assessment ahead of their own when bothhave been injured. It can also occur if a grandparent,
perhaps at the younger end of the age spectrum, is a
cocaine smoker. Cocaine use by any route can also result
in myocardial infarction.
Evaluation of a Grandparent withChest Pain in the Pediatric EDThe history is the most significant part of the evaluationbecause there are often no abnormal clinical signs. Even
after a comprehensive history and physical examination,
with supporting investigations such as an ECG, the
diagnosis may still prove to be elusive to the emergency
pediatrician, and later to the general emergency physician
or specialist in internal medicine. It is reassuring to
remember that most patients presenting to an ED with
chest pain do not have significant disease. It is essential,however, to maintain a high index of suspicion that the
cause of chest pain could be life-threatening.
HistoryEstablishing the history of a grandparent’s chest pain
follows the same principles as in children. History taking
must be concise yet comprehensive, and include past and
concurrent medical history, recent surgery or trauma,
risk factors for cardiovascular disease, social history(which may be relevant to safe discharge), and use of
both prescription and nonprescription drugs.
The nature and location of chest pain can indicate the
underlying cause in some patients, but in most cases,
the diagnosis will remain unclear (Table 2). Asso-
ciated symptoms, including back pain, cough, diapho-
resis, dyspnea, and nausea and vomiting, should be
elicited. A history of collapse or loss of consciousnessshould be sought.

may reflect anxiety, severity of the pain, or cardiovas-
cular compromise. Ill appearance should always causeimmediate concern for the presence of a life-threat-
ening disorder.
Vital Signs
Remember that children are not small adults and adults are
not large children. Physiological parameters that are

normal in children may reflect serious hemodynamic
instability in adults. A pulse rate more than 100 perminute represents tachycardia in an adult and could result
from a cardiac problem, such as pericarditis. A weak
thready pulse is a sinister finding and indicates impending
cardiac failure or deteriorating cardiac function.A blood pressure of 90/60 mm Hg is certainly accept-
able in a 5-year-old but may represent cardiogenic shock,

secondary to a myocardial infarction, in a 55-year-oldgrandparent complaining of central crushing chest pain.Manual recording of the blood pressure may be necessaryin the ill grandparent with chest pain, because automateddigital recording can be inaccurate.
Hypertension associated with chest pain, with adiastolic blood pressure greater than 90 mm Hg, couldbe the result of anxiety, pain, or serious pathology. Asystolic blood pressure difference of greater than 20 mmHg between the upper limbs can result from aorticdissection. Radial-femoral delay may also be found inaortic dissection.
A respiratory rate of 30 may be normal in a smallchild, but in a 60-year-old grandparent with pleuriticchest pain, it may result from hypoxia in the presenceof a PE. A low oxygen saturation, which does notimprove with supplemental oxygen, could suggest thediagnosis of a PE. The grandparent with pericarditis orpneumonia, for example, can be febrile, but thetemperature may be low in the seriously ill. It is alsoimportant to recognize that normal vital signs in agrandparent with chest pain do not exclude a life-threatening condition.
Cardiorespiratory System
Examination is frequently normal and may not be helpful
toward making the diagnosis. Signs of injury to the chest
wall may point to the presence of a pneumothorax, or a
pulmonary or cardiac contusion resulting in chest pain,before further examination is completed. Paradoxical
filling of the neck veins in inspiration, Kussmaul’s sign,
suggests a diagnosis of PE or pericarditis, but is a rare
finding in clinical practice.
Crackles or wheezes in the lung fields must be
interpreted according to a grandparent’s presenting
symptoms and history. Cardiac failure compromising
oxygenation can point to a provisional diagnosis ofmyocardial infarction, especially if associated with hypo-
tension. Heart murmurs are unlikely to be helpful in
reaching a diagnosis. A pericardial rub, best heard at the
lower left sternal border, with the patient sitting forward
in full expiration, is pathognomonic of pericarditis.
Management of a Grandparentwith Chest Pain by theEmergency PediatricianThe early management of the adult who presents with
chest pain should result in the following interventions.
OxygenSupplemental oxygen should be commenced in all
patients suspected of having a life-threatening cause of
their pain. High concentrations of oxygen are beneficial
to most patients and can be life saving. A minority of
patients with chronic obstructive pulmonary disease
depend on hypoxia to stimulate respiration. The oxygen
can then be titrated according to respiratory rate and
effort, level of consciousness, and oxygen saturation,
which should be maintained around 90% [5].
Intravenous AccessBlood samples should be obtained when intravenous
access is established. These should include a completeblood cell count and electrolytes. Subsequent evaluation
may also be aided by obtaining a baseline creatine kinase
or troponin level. A sickle test should be performed if
previously undiagnosed sickle cell disease is suspected of
causing chest pain. A clotting screen and a cross-match
sample are essential if aortic dissection is suspected. If the
children’s hospital does not routinely perform some of
these baseline studies, the labeled blood samples canaccompany the patient to the receiving adult ED. It is
imperative that such samples be clearly identified
and timed.
Pain ManagementWhen ACS is suspected, reversal of cardiac ischemia bynitroglycerin can provide effective pain control. Patientswith a history of angina may have tried their ownnitroglycerin without effect. If not, 0.4 mg of nitro-glycerin should be given sublingually, if available, andrepeated every 5 up to 15 minutes as needed. Nitro-glycerin is also beneficial in the presence of hypertension.It is important for the emergency pediatrician toremember that administration of nitroglycerin within24 hours of the patient taking sildenafil (Viagra) orsimilar agents is likely to precipitate hypotension andshould be avoided.
Intravenous morphine, titrated to patient need inincrements of 2 mg, should be considered for those with
severe chest pain. Morphine is typically a fast-acting and
effective intervention for severe pain, particularly in those
who fail to achieve relief with nitroglycerin. Morphine
can also be beneficial in the presence of concurrent
pulmonary edema. Pediatricians should be aware that a
recent published study has raised concerns about the
safety of the routine use of morphine in ACS, advisingthat pain relief be primarily addressed with nitroglycerin
[6]. An anti-inflammatory drug such as ibuprofen should
be considered if pericarditis is suspected.
Therapy Beneficial to OutcomeAntiplatelet therapy in the form of aspirin (325 mg)
reduces mortality independently of thrombolytic therapy
and should be given at the earliest opportunity to all
patients suspected of having ACS and not currently taking
salicylates [7]. As aspirin is rarely used in pediatric care, it
might not be readily available in the pediatric ED. For this

scenario alone, aspirin should be stocked in all EDs,
including those in specialized pediatric facilities, so as not
to delay its administration. Intravenous furosemide (20
mg) can improve oxygenation and should be considered
when acute cardiac failure is present.
Appropriate MonitoringAn initial ECG should be obtained promptly upon any
adult’s presentation with any chest pain. Cardiac mon-
itoring should be commenced at the earliest opportunity
to detect arrhythmias and should be continued during
transfer to an adult facility. If transfer is delayed, the ECG
should be repeated every 30 to 60 minutes. Pulse,
respiratory rate and blood pressure, including differential
blood pressures in the arms if aortic dissection is
suspected, should be recorded every 15 minutes, and
oxygen saturation recorded continuously.
Chest RadiographyThe chest radiograph is frequently not helpful in ex-
plaining the cause of chest pain. A widened mediastinum
is seen in less than 50% of patients with aortic dissection.
Other abnormalities, including aortic calcification and
dilatation of the thoracic aorta, are nonspecific in aiding
the diagnosis. An unsuspected pneumothorax or pneumo-
nia may be seen on chest x-ray. Obtaining a chest
radiograph should not delay transfer to an adult ED.
Rapid Safe Transfer to an Adult EDThe patient should be transported by paramedics in anadvanced life support–equipped vehicle to a nearbycapable adult ED for further assessment and treatment.
Initiation of Basic and Advanced Life Supportin the Event of Cardiac ArrestAlgorithms for basic and advanced life support in anadult, recommended by the American Heart Association[8], should be followed. The algorithms are the same asthose for an older child, over 8 years, and require thesame drugs and equipment, which should be readilyavailable in the pediatric ED.
SummaryThe etiology of acute undifferentiated chest pain in agrandparent may be difficult to establish, even for
a specialist in adult emergency care or internal medi-cine. Faced with such a patient, the emergency pedia-trician should focus on measures that provide afoundation for excluding life-threatening illness andoptimizing outcome. Such measures, as discussed in thispaper, should be well within the capability of allemergency pediatricians.
