【摘要】 目的 旨在探讨是否在常规2-DE左室心尖部血栓的出现预示无存活心肌的存在。 方法 80例心肌梗死患者接受DSE检查，根据心室内有无血栓分为血栓组(1组)及无血栓组(2组)，比较两组的室壁运动积分及射血分数。 结果 48例患者被证实高度怀疑有左室血栓(1组)，32例患者无左室血栓(2组)。1组比2组有更高的室壁积分;1组的32例(67%)及2组中8例(25%)患者证明在心尖节段无收缩储备即无存活心肌。 结论 在无存活心肌存在的相应节段左室心尖部血栓更易出现。

    【Abstract】 Objective The aim of this article was to determine whether the presence of left ventricular throm-bus is a marker of nonviable myocardium.Methods Eighty patients with myocardial infarction(MI)were studied by dobutamine stress echocardiography(DSE)left ventricular apical was identified using echocardiographic criteria;thus ......
