Exercise-Induced Angina with Intermittent ST-Segment Elevation.

Exercise-induced ST segment elevation. Electrocardiographic, angiographic, and scintigraphic evaluation.

Two hundred and fifteen patients with previous myocardial infarction were investigated between four and six months after the acute episode by computer assisted 12 lead exercise electrocardiography. Thirty-six (17%) out of this group showed ST segment elevation over the infarct zone, reflected by leads presenting with "QS" configuration. They were further investigated by serial thallium-201 scin...

Coronary arterial spasm as a cause of exercise-induced ST-segment elevation in patients with variant angina.

Four patients with variant angina pectoris exhibited reproducible exercise-induced chest pain and ST-segment elevation. Coronary arterial spasm was documented with arteriography during exercise-induced ST-segment elevation (three patients) or after intravenous administration of ergonovine maleate (one patient). Our observations show that in patients with variant angina exercise can trigger coro...

Reciprocal ST-segment depression associated with exercise-induced ST-segment elevation indicates residual viability after myocardial infarction.

OBJECTIVES We evaluated the clinical significance of reciprocal ST-segment depression associated with exercise-induced ST-segment elevation for detecting residual viability within the infarcted area. BACKGROUND Although the relation between residual viability and exercise-induced ST-segment elevation has been described, there are no reports focusing on the relation between myocardial viabilit...

Left and right heart haemodynamics during spontaneous angina pectoris. Comparison between angina with ST segment depression and angina with ST segment elevation.

The function of both right and left sides of the heart was studied during spontaneous attacks of angina pectoris at rest in 7 patients showing ST depression (type I) and 4 showing ST elevation (type II) during the attack. In none of the 44 type I attacks and 29 type II attacks which were recorded did circulatory changes; the latter were different in the two groups. Type I attacks showed: a) a b...
