【摘要】 目的 分析心肌桥的临床特征。方法 回顾性分析住院患者362例行选择性冠状动脉造影检出的52例心肌桥患者的临床特征。结果 心肌桥在冠状动脉造影检出率为14.36%;心肌桥最常出现在左前降支;心肌桥患者临床表现出不同程度的心绞痛、心律失常、心肌梗死及不同程度的心电图、E/A、CTnI、vWF:Ag改变;药物、PCI及手术可治疗心肌桥患者。结论(1)心肌桥可以引起心肌缺血症状;(2)心肌桥可继发动脉粥样硬化的形成;(3)左心室肥厚、高血压、糖尿病和心肌病与心肌桥的临床发生有关;(4)有症状的心肌桥首选药物治疗，无效时考虑PCI及手术治疗。

    【Abstract】 Objective To study the clinical manifestation of myocardial bridge.Methods A restrospective analysis was made on the data of the clinical manifestation of52patients with myocardial bridge out of362patients undergoing coronary angiography.Results Positive rate of myocardial bridge was14.36%.Usually，the left anterior coronary artery has been involved.Clinically，all the52patients were having symptoms of angina or myocardial infarcˉtion，severe arrhythmia，ECG，E/A，CTnI，vWF:Ag.The prognosis of myocardial bridge is good.Conclusion (1)

    The construction of coronary myocardial bridge result in ischemic heart disease.(2)Myocardial bridge tends to promote the atherosclerosis of the vessels.(3)Left ventricular wall hypertrophy ......
