Anterior myocardial infarction with coronary thrombus formation secondary to acute coronary vasospasm. A case report

Abstract

An acute myocardial infarction in a young man when there was no fixed atherosclerotic lesion in the coronary arteries is reported. Soon after the myocardial infarction the patient was shown to have thrombosis in the anterior descending branch of the left coronary artery but this later disappeared. In view of recurrent angina pectoris, provocation tests were undertaken with ergometrine maleate, cold pressor and hyperventilation. Both the drug and the hyperventilation provoked coronary spasm accompanied by angina pectoris but no ECG evidence of ischaemia.
