摘　　要：目的探讨多层螺旋CT冠状动脉成像评价心肌桥与冠状动脉粥样硬化关系的应用价值。方法选取100例拟诊为冠心病行多层螺旋CT冠状动脉成像扫描的患者,评价其心肌桥的长度、厚度及其伴随的动脉粥样硬化情况。并按心肌桥存在与否分为心肌桥组与无心肌桥组,比较两组动脉粥样硬化的发生率。结果 100例患者中30例发现心肌桥(30.0%),左前降支(LAD)段的发生率最高。LAD的心肌桥组与无心肌桥组相应节段的冠状动脉狭窄程度比较,差异有统计学意义(χ2=13.0481,P<0.05)。结论心肌桥不能仅视为解剖变异,而应引起临床医生的重视,心肌桥可能是评估冠心病的危险因素之一。Objective To explore the application value of multi slice spiral CT coronary artery imaging to evaluate the relationship between myocardial bridge and coronary atherosclerosis. Methods Multi slice spiral CT scan was under- went in 100 patients with suspected coronary heart disease,length and thickness of myocardial bridge and atherosele- rosis accompanied by myocardial bridge was evaluated.Then patients were divided into the myocardial bridge group and no myocardial bridge group,incidence of coronary atherosclerosis was compared. Results Among 100 subjects,30 subjects （30.0%） were found to have myocardial bridge,incidence of left anterior descending （LAD） artery was highest. The degree of coronary artery stenosls of the corresponding segments in the myocardial bridge group and no myocardial bridge group of LAD was c0mpared, and there was a statistical difference between the two groups （X2=13.0481 ,P〈0.05）. Conclusion Myocardial bridge is not only regarded as the anatomic variation,and it should be paid more attention by clinicians,myocardial bridge may be one of the risk factors for the assessment of coronary artery disease.
