A 63-year-old man with an acute anterior myocardial infarction demonstrated an intracoronary nonocclusive thrombus distal to the organic stenosis of the left anterior descending coronary artery. One month after the infarction the thrombus was completely dissolved, and spontaneous and provoked spasm occurred overlying the organic stenosis of the coronary artery. Thus coronary spasm superimposed on the atherosclerotic stenosis was suggested as a cause of the thrombus formation that led to myocardial infarction.
一名63岁男性，患有急性前壁心肌梗死，其左前降支冠状动脉器质性狭窄远端出现冠状动脉内非闭塞性血栓。心肌梗死后1个月，血栓完全溶解，在冠状动脉器质性狭窄部位出现自发性和诱发性痉挛。因此，冠状动脉痉挛叠加在动脉粥样硬化狭窄之上被认为是导致心肌梗死的血栓形成的原因。
