- Abstract
Fourteen patients with variant angina underwent ergonovine testing during diagnostic coronary angiography. The clinical electrocardiographic or angiographic manifestations of coronary artery spasm could not be reproduced in six of these patients. Five patients had chest pain and transient ST-segment elevation within 4 days of the ergonovine study, including three who developed coronary spasm in the catheterization laboratory. It appears that the sensitivity of ergonovine testing in the diagnosis of coronary spasm is lower than previously emphasized.
