摘　　要：目的探讨心肌桥合并冠状动脉粥样硬化患者的临床及冠脉造影特征。方法收集2005-2009年在我院经选择性冠状动脉造影证实的42例心肌桥患者的临床资料，根据造影结果将患者分为单纯性心肌桥组（19例）与心肌桥合并冠状动脉粥样硬化组（23例），分析比较两组临床特点和造影结果。结果两组在性别及冠心病危险因素上差异无统计学意义，但心肌桥合并冠状动脉粥样硬化狭窄组存在2个或2个以上冠心病危险因素的概率要明显高于单纯心肌桥组。冠状动脉粥样硬化多发生于邻近心肌桥部位，其临床上多表现为急性冠脉综合征。结论心肌桥可能导致其邻近部位发生冠状动脉粥样硬化损伤并加速其进展。心肌桥合并冠状动脉粥样硬化患者可能发生更为严重的临床事件。Objective To investigate the clinical and angiographie characteristics of the patients with myocardial bridges （MB） in addition to atheresclerotie lesion found on coronary angiography. Methods The present study included 42 patients with MB found on coronary angiographies performed in our hospital from 2005 to 2009. Based on the findings on angiography, the patients were subdivided into two groups： patients had myocardial bridges（n=19） only and patients had MB in addition to atheroselerotie lesion（n=23）.The graphic and clinical characteristics of both groups were compared. Results There were no differences between two groups in distribution of gender and risk factors of coronary artery disease. Frequency of two or more risk factors for coronary artery disease in a particular patient was significantly higher in the group MB＋AS. Atherosclerotic nalTowing developed in proximaly to the MB. Clinically, acute coronary syndrome was more frequently in group MB＋AS. Conclusion Myocardial bridges may initiate the development of atherosclerotie lesion or may facilitate progression of atherosclerosis in the proximal segment of the vessel. The risk of acute coronary syndrome rises when atherosclerosis is superimposed on MB.
