目的探讨超声指标--心肌机能指数(Tei)与血浆脑钠肽(BNP)水平鉴别收缩性心力衰竭(SHF)及舒张性心力衰竭(DHF)的临床应用价值.方法入选心力衰竭患者67例,按照左室射血分数(LVEF)分为SHF(LVEF<50%)及DHF组(LVEF≥50%).32名健康者为对照组,测常规超声指标及Tei指数,并采用ELISA法测得血浆BNP水平.结果与对照组相比,DHF及SHF组Tei指数、BNP显著增高(P<0.01);心力衰竭两组相比,Tei指数、BNP在SHF组显著升高(0.63±0.11)比(0.82±0.20)ng/L,P<0.01;713.38ng/L,比1345.86ng/L,P<0.05,且二者呈显著正相关(r=0.71,P<0.01).结论 Tei指数、BNP在心力衰竭患者显著升高,二者可鉴别SHF及DHF.
