Answer

Exercise stress testing can be useful in establishing the diagnosis of significant obstructive CAD when the diagnosis is in question. Although other clinical findings (eg, dyspnea on exertion, resting electrocardiographic [ECG] tracing abnormalities, or multiple risk factors for atherosclerosis) may suggest the possibility of CAD, the most important clinical finding is a history of chest discomfort or pain. Myocardial ischemia is the most important cause of chest discomfort or pain and is most commonly a consequence of underlying CAD.
