The exercise stress test is a useful screening tool for the detection of significant coronary artery disease. Documentation of the patient's symptoms, medications, past and current significant illnesses, and usual level of physical activity helps the physician determine if an exercise stress test is appropriate. The physical examination must include consideration of the patient's ability to walk and exercise, along with any signs of acute or serious disease that may affect the test results or the patient's ability to perform the test. The test report contains comments about the maximal heart rate and level of exercise achieved, and symptoms, arrhythmias, electrocardiographic changes and vital signs during exercise. Despite advances in disease prevention, coronary artery disease remains a major cause of illness and death in the United States. The exercise stress test is a useful tool for detecting coronary artery disease and for evaluating medical therapy and cardiac rehabilitation following myocardial infarction. Stress scintigraphy can be performed with pharmacologic agents instead of exercise if the patient's condition does not allow sufficient physical activity for performing the study. Echocardiography has recently been used in combination with exercise or pharmacologic stress testing as yet another form of noninvasive cardiac evaluation. The Joint Commission on Accreditation of Healthcare Organizations requires that institutions assess competence on the basis of criteria established in the medical staff bylaws. A combined specialty task force, composed of members from the American College of Cardiology ACC , the American College of Physicians and the American Heart Association AHA , in 1996 issued a statement on clinical competence in exercise testing. Equipment requirements for exercise stress testing include a bicycle ergometer or treadmill, a monitor system, a medical crash cart and a defibrillator. Personnel requirements include the examiner and one other person trained in basic cardiac life support, although someone with advanced cardiac life support skills is preferred. Particularly difficult to detect is evidence of fixed stenoses with collateral blood flow, as well as low-grade less than 50 percent stenoses. These abnormalities may not produce sufficient impairment of blood flow to affect the ECG. Some studies indicate that low-grade stenoses are often the source of spontaneous thrombosis, leading to the sudden development of significant stenosis, infarction and sudden death because such lesions do not have the benefit of collateral blood flow. An exercise stress test would not be helpful in detecting this type of lesion. The estimation of the pretest probability of a significant fixed stenosis should be based on the patient's age, gender, symptoms, concurrent medical conditions, medications and physical examination, as well as on the clinician's diagnostic experience with symptoms of myocardial ischemia. This information is helpful for determining the potential utility of an exercise stress test for a given patient. Consideration may be given to obtaining this test when patients present with symptoms of coronary artery disease, including the classic anginal symptoms of chest pressure or pain that occurs with or without exertion. Atypical presentations or anginal equivalents, such as shortness of breath or dyspnea on exertion, are also appropriate indications for this study.

Patients with coronary artery disease who have undergone surgical intervention or are receiving medical therapy can perform an exercise stress test when they are medically stable and symptom-free. The study can be used to assess the effectiveness of treatment. After myocardial infarction, patients may be candidates for exercise stress testing at a low level of exercise to determine functional capacity and identify any ECG changes or symptoms during exercise. With this information, the clinician is often able to prescribe an exercise regimen or more aggressive therapy, or to select the appropriate tests for further evaluation. In addition, the American College of Sports Medicine ACSM recommends an exercise stress test for all women 50 years of age and older and all men 40 years of age and older who plan to engage in vigorous exercise. The ACSM does not recommend exercise stress testing for asymptomatic healthy persons who are not planning vigorous exercise, regardless of the person's age. An exercise stress test may also be considered in asymptomatic patients who have two or more risk factors for coronary artery disease or a concurrent chronic disease, such as diabetes, that carries a high risk of coronary disease. Patients with valvular disorders except those with hemodynamically significant aortic stenosis may undergo an exercise stress test to evaluate their functional capacity, the effectiveness of treatment, their symptom complex or the need for surgical inter
