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.
报告了一名年轻男性发生急性心肌梗死,而冠状动脉中并无固定的动脉粥样硬化病变。心肌梗死后不久,患者被发现左冠状动脉前降支有血栓形成,但血栓后来消失了。鉴于复发性心绞痛,采用马来酸麦角新碱、冷加压和过度通气进行激发试验。药物和过度通气均诱发了冠状动脉痉挛并伴有心绞痛,但心电图无缺血证据。
