Revelation of a myocardial bridge has been described at coronary angiography. The pathophysiology of myocardial bridging is incompletely understood. It is sometimes associated with overt pathology, as well as it can just be an incidental finding without any significance. It has been also reported an acute myocardial infarction with normal coronary arteries associated with iatrogenic hyperthyroidism. We present a case of acute myocardial infarction in a 28-year-old Italian man with normal coronary arteries, iatrogenic elevated levels of free triiodothyronine and myocardial bridge.
在冠状动脉造影中已经描述了心肌桥的显现。心肌桥的病理生理学尚未完全了解。它有时与明显的病理有关，也可能只是没有任何意义的偶然发现。也有报道称，与医源性甲状腺功能亢进症相关的正常冠状动脉急性心肌梗死。我们报告了一例 28 岁意大利男性的急性心肌梗死病例，其冠状动脉正常，三碘甲状腺原氨酸游离水平升高，存在心肌桥。
