摘要 目的探讨老年慢性心力衰竭(CHF)患者血清高敏肌钙蛋白T(hs-cTnT)与心功能变化的关系。方法选取老年CHF136例为心衰组,依据NYHA心功能分级分为4个亚组,Ⅰ级组32例;Ⅱ级组36例;Ⅲ级组31例;Ⅳ级组37例。选取同期老年健康查体者30例为对照组。所有入选对象测血清hs-cTnT及血浆N末端脑钠肽(NT-proBNP)浓度,并行超声心动图检查。结果①心衰组较对照组hs-cTnT浓度显著升高(P<0.001);心衰各亚组间hs-cTnT比较均有显著差异(P均<0.05)且随NYHA分级增加而升高(P<0.001);Ⅰ级组较对照组hs-cTnT浓度升高(P<0.05)。心衰组与对照组比较以及心衰组内各亚组之间比较超声心动图参数、NT-proBNP浓度有显著差异(P<0.05)。②心衰患者Log hs-cTnT与Log NT-proBNP、LAd、LVEDd呈正相关(r分别为:0.424,0.431,0.640,P均<0.05),与LVEF呈负相关(r=-0.477,P<0.05)。结论老年CHF患者无论有无心衰症状hs-cTnT均升高,其升高程度与心衰严重程度正相关,hs-cTnT能较好地反映患者心功能变化。
