摘　　要：【目的】探讨冠脉造影中心肌桥的检出率及其临床意义。【方法】根据冠状动脉造影显示冠状动脉管腔收缩期狭窄判定心肌桥,并根据收缩期狭窄程度分为3级。【结果】447例行冠状动脉造影的患者中共检出心肌桥10例,检出率2.2%,全部位于左前降支。2例在心肌桥近端有粥样硬化病变,管腔固定狭窄达70%以上,置入支架。其他有症状病例经药物治疗,临床症状消失。【结论】冠状动脉造影时收缩期狭窄是判定心肌桥的惟一依据,心肌桥可导致缺血性心脏事件,对有缺血症状者应予适当治疗。[Objective]To study the rate of coronary artery myocardial bridge in coronary angiography and its clinical characteristics. [Medthods]Myocardial bridges were detected only when the systolic narrowing occurred. [Results]Angiographic evidence of myocardial bridges over left anterior descending branch was 10 in 447 patients. The rate of myocardial bridges was 2.2%. Two patients had atherosclerosis in the proximal cor onary arteries to myocardial bridges. Coronary artery myocardial bridges were treated effectively by medicine or stenting. [Conclusion]Systolic narrowing is the important evidence of myocardial bridge in coronary angiography. Myocardial bridge can result in myocardial ischemia. Some treatments are necessary in ischemic c ase.
