We report here a young male athlete who had an acute myocardial infarction after strenuous exercise. Coronary angiography clearly demonstrated thrombus formation within a prominent myocardial bridge. Periarterial resection surgery was performed, which resulted in resolution of the angiographic "milking" effect of muscle bridge. Our observation, along with previous reports, suggests that myocardial bridges should be added to the list of known causes of sudden death or myocardial infarction in young persons after strenuous exercise. Thrombus formation within a myocardial bridge may be a potential mechanism whereby this anatomic curiosity may cause a tragic clinical event.
我们在此报告一名年轻男性运动员，其在剧烈运动后发生急性心肌梗死。冠状动脉造影清楚地显示在一个明显的心肌桥内形成了血栓。进行了动脉周围切除术，这使得肌肉桥的血管造影“挤奶”效应得以消除。我们的观察结果以及之前的报告表明，心肌桥应被列入年轻人剧烈运动后猝死或心肌梗死已知病因的清单中。心肌桥内血栓形成可能是这种解剖学异常情况导致悲惨临床事件的一种潜在机制。
