Abstract: 目的:探讨冠状动脉心肌桥与缺血性心脏病(IHD)的关系.方法:对用常规方法行选择性冠状动脉造影检出的19例冠状动脉心肌桥的患者临床资料进行回顾性分析.结果:2018例中共检出冠状动脉心肌桥19例,发生率为0.94%.19例中有16例符合IHD的临床诊断标准;其中心肌桥段冠状动脉收缩期狭窄百分比(PSN)等于或大于75%者的心肌桥近段冠状动脉粥样硬化的发生比例(11/13)和严重程度[0~3(2)]均大于PSN小于75%者[(1/6)和1~0(2)],P<0.05.结论:冠状动脉心肌桥可导致缺血性心脏病,心肌桥近段冠状动脉粥样硬化的发生可能与肌桥段冠状动脉收缩期狭窄的程度有关.
