摘要 随机选取因胸痛而行冠状动脉(冠脉)造影检查的患者56例,根据冠脉造影结果,41例确诊冠心病的患者被分为1支病变组、2支病变组和3支病变组,另外15例排除冠心病者作为对照组。采用组织多普勒成像技术测定各组二尖瓣环室间隔、心室侧壁、前壁与下壁四个位点的收缩期、舒张早期和晚期组织运动速度,比较对照组与各病变组二尖瓣环收缩期(Sa)、舒张早期(Ea)、舒张晚期(Aa)组织运动速度和Ea/Aa。结果显示,对照组与各病变组之间的Sa与Aa相比,P均>0.05,Ea和Ea/Aa相比,P均<0.05;三个病变组的Sa、Ea、Aa和Ea/Aa相比,P均>0.05。认为冠心病患者心室舒张功能先于收缩功能受损,采用组织多普勒成像技术检测二尖瓣环组织运动速度,可为评价冠脉病变患者的心室功能提供参考依据。
