  • Abstract
  • Look Inside

Thirty-seven patients with resting angina pictoris and coronary arterial spasm confirmed by coronary angiography were examined. Coronary arterial spasm was evidenced by coronary angio-graphy during their spontaneous attacks in 9 patients or induced attacks by ergometrine maleate (26 patients) or hyperventilation (2 patients). Seventeen patients had history of effort angina as well as angina at rest.

Master's two step test and/or multistage tread-mill exercise test were performed in all patients. Twenty-one of 37 patients had positive exercise test. There was no statistical difference in the percentage of exercise-positive patients between those who had significant organic stenosis and those who had not. The location of ST changes in 21 patients with positive exercise test was identical to that during spontaneous attacks orthat induced coronary arterial spasm, and the site of ischemic ST changes corresponded to the loca-tion of coronary arterial spasm documented by coronary angiography. Among those with posi-tive exercise test, 12 patients had no significant stenosis, indicating that coronary arterial spasm could be induced by exercise test.
