摘要 目的:分别用脉冲血流频谱多普勒测量法(传统法)和脉冲组织多普勒测量法(TDI法)测算Tei指数,比较两种方法测得的Tei指数在诊断心力衰竭时的临床应用价值。方法:测量97例研究对象的Tei指数,其中左室射血分数下降的心力衰竭组(HfrEF组)35例,左室射血分数正常的心力衰竭组(HfnEF组)34例,对照组28例。结果:传统法:Tei指数在轻度HfrEF组与中重度HfrEF组之间有统计学差异(P<0.05);TDI法:Tei指数在对照组与HfnEF组间及轻度HfnEF组与中重度HfnEF组间有统计学差异(P<0.05)。结论:当患者室壁运动均匀时,TDI法测量Tei指数诊断价值可能优于传统法;但是当患者存在有不同室壁间的节段性搏动异常时,传统法则优于TDI法。
