Myocardial bridge refers to the myocardial tissue with which the coronary artery is partly covered. Though it has long been regarded to be benign, patients with myocardial bridges may present with myocardial ischemia, acute coronary syndromes, coronary spasm, sudden cardiac arrest or even sudden death.
In present study, we reviewed four cases with myocardial bridge and no stenosis of coronary artery, which included acute coronary syndrome and sudden cardiac arrest.
These cases indicated that cardiac events in patients with myocardial bridge may be associated with coronary spasm, myocardial supply/demand mismatch or cardiac arrest.
心肌桥是指部分覆盖冠状动脉的心肌组织。尽管长期以来一直被认为是良性的，但心肌桥患者可能会出现心肌缺血、急性冠状动脉综合征、冠状动脉痉挛、心脏骤停甚至猝死。
在本研究中，我们回顾了4例冠状动脉无狭窄的心肌桥病例，其中包括急性冠状动脉综合征和心脏骤停。
这些病例表明，心肌桥患者的心脏事件可能与冠状动脉痉挛、心肌供需不匹配或心脏骤停有关。
