摘　　要：目的 探讨64层螺旋CT冠状动脉成像对心肌桥相关冠状动脉粥样硬化的应用价值.方法 回顾性分析829例患者CT冠状动脉检查的资料.按年龄分为青年、中年、老年3组,分析心肌桥的检出率、肌桥相关血管粥样硬化的发生率及粥样斑块的性质.结果 829例患者检出肌桥204例,检出率24.6%.肌桥合并冠状动脉粥样硬化86例,其中肌桥相关血管粥样硬化60例.肌桥近段粥样硬化发生率高于远段血管（P＆lt;0.05）.青年组、中年组与老年组的肌桥检出率无差异（P＞0.05）,但3组中肌桥相关血管粥样硬化的发生率及粥样斑块的性质不同 （P＆lt;0.05）.结论 多层螺旋CT对心肌桥及肌桥相关冠状动脉粥样硬化的诊断价值较高.伴有肌桥的冠状动脉粥样硬化的发生率与年龄相关,斑块性质随年龄增长有所不同.Objective To discuss the application value of 64-slice spiral computed tomography coronary angiography for myocardial bridge related coronaryatherosclerosis. Methods To retrospective analysis the data of a total of 829 patients underwent CT coronary artery inspection. According to the patient＇s age we divided patients into 3 groups, including a young group, a middle-aged group and an old group, and then analyzed the detection rate of myocardial bridge, and the incidence of myocardial bridge related vascular scleratheroma, and the nature of atherosclerotic plaque. Results A total of 204 cases of myocardial bridge were found in 829 patients, the detection rate was 24.6%; and 86 of them also having got coronaryatheroselerosis, among them 60 were myocardial bridge related vascular scleratheroma, proximal myocardial bridge had a higher incidence of plaque than distal myocardial bridge （P〈0.05）. The detection rate of myocardial bridge had no statistical difference in the young, middle aged and old group（P〉0.05）, but the incidence of atheromatous plaque related myocardial bridge and the nature of plaque were different among the 3 groups, the difference was statistically significant（ P〈0.05 ）. Conclusion Multi-slice spiral computed tomography has a high diagnostic value for myocardial bridge and it related coronary atherosclerosis. The incidence of coronary atherosclerosis with myocardial bridge is related to age, and the nature of the plaque is different with the growth of the age.
