A 65-year-old man admitted with a diagnosis of acute myocardial infarction with recurrently preceded anginal symptoms. He had experienced coronary angiography several years ago, and was diagnosed as vasospasticangina. But his medical compliance was poor. At emergent coronary angiography, spontaneous spasm of the proximal circumferential branch appeared, and his electrocardiography showed typical ST elevation in the leads of II , III, aVF, at the same time. Intracoronary nitroglycerin resolved the coronary spasm and we could find no abnormal region in any other coronary artery. His left ventriography showed broad inferior and lateral dysfunction. From these clinical profiles, his left ventricular dysfunction seemed to be caused by recurrent vasospasm. This is a rare case which shows a direct evidence that coronary vasospasm caused acute myocardial infarction.
