摘　　要：目的:分析冠状动脉心肌桥的双源CT特征与临床事件的关系。方法:分析40例心肌桥患者的双源CT资料和临床资料,依据心肌桥是否合并桥前动脉粥样硬化性狭窄将患者分为单纯心肌桥组和复杂心肌桥组,比较2组患者的年龄、性别、收缩压、舒张压、脉压、左心室重量指数、心肌桥长度、LVEF、血糖、血脂等因素,比较上述因素与心肌桥合并桥前狭窄的相关性。结果:复杂心肌桥组收缩压、脉压、左心室重量指数均显著高于单纯心肌桥组(P<0.05),收缩压、脉压、左心室重量指数与心肌桥合并桥前狭窄相关。结论:心肌桥合并桥前动脉粥样硬化性狭窄可以引起急性冠脉综合征,收缩压、脉压、左心室重量指数是合并桥前动脉粥样硬化性狭窄的主要危险因素。Objective：To analyze the relationship between the angiographic features of coronary myocardial bridge（CMB） and its clinical events. Methods：We analyzed the angiographic and clinical data of 40 myocardial bridge patients. Patients were divided into simple CMB group and complex CMB group groups by whether there was atherosclerotic stenosis before myocardial bridge. We compared the age,gender,systolic blood pressure（SBP）,diastolic blood pressure（DBP）,pulse pressure（PP）,left ventricular mass index （LVMI）,length of the bridge,left ventricular ejection fraction,level of blood glucose and total cholesterol of the two groups and then studied if they were related to the degree of CMB pre-stenosis. Results：The SBP,PP,LVMI in the complex CMB group were significantly higher than those in the simple CMB group. The SBP,PP,LVMI were related to the degree of CMB pre-stenosis. Conclusions：The atherosclerotic lesions before CMB may induce acute coronary syndrome in CMB patients. SBP,PP,and LVMI play an important role in pre-CMB atherosclerotic lesions.
