Abstract

67 patients with angina at rest associated with transient ST segment elevation performed maximal exercise (bicycle) test and underwent coronary arteriography. Exercise electrocardiogram was normal in 24 (group I), exhibited ST elevation in 22 patients (group II) and ST depression in 21 patients (group III). It is concluded that the exercise electrocardiogram can display ischemic changes in patients with variant angina. ST segment depression is a more common finding in patients with multivessel disease, while ST elevation is more frequent in those with single-vessel involvement. In patients with normal coronary arteries or with minor atherosclerotic changes, the exercise test can precipitate anginal pain associated with ST segment elevation. Evidence of spasm of the right coronary artery in 2 such patients during exercise-induced ST segment elevation provides a logical explanation for the phenomenon. Thus, coronary vasoconstriction may be triggered also by exertion and plays a role in exercise-induced angina associated with ST segment elevation.
