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.
