【摘要】 目的　探讨冠状动脉心肌桥 (心肌桥 )的特征和心肌桥与缺血性心脏病 (IHD)的关系。方法　回顾性分析接受冠状动脉造影的 2 398例患者 ,其中共检出心肌桥 2 2例。结果　心肌桥检出率为 0 92 % ;心肌桥最常出现在左前降支 ;心肌桥段冠状动脉收缩期狭窄是最主要征象 :心肌桥近段冠状动脉粥样硬化检出率为 5 4 5 % ;有心肌桥患者临床均表现出不同程度心绞痛和心肌梗死。结论　冠状动脉收缩期狭窄是心肌桥最主要征象 ;冠状动脉心肌桥可导致缺血性心脏病。更多还原

【Abstract】 Objective To investigate the characteristics of coronary artery in myocardium bridge and the correlation between myocardium bridge and ischemic heart disease (IHD) Methods We found 22 patients with myocardium bridge in 2?398 patients receiving coronary arteriongraphy by a retrospective analysis Results Positive rate of myocardium bridge was 0 92% Usually, the left anterior coronary artery had been involved, with the main sign of constructive stenosis, and 54 5% of the nearby coronary arteries in myocardium bridge area were with atherosclerosis Clinically, all the 22 patients were having symptoms of angina or myocardial infarction Conclusion Constructive stenosis is the major character of myocardium bridge The construction of coronary in myocardium bridge results in ischemic heart disease更多还原
