摘要 目的探究血浆和肽素水平与左心室射血分数正常的心力衰竭(HFNEF)之间的关系。方法选取中国人民解放军第八九医院HFNEF患者97例作为HFNEF组,并按纽约心脏病协会(NYHA)分级,将97例患者分为Ⅰ~Ⅱ级组(34例)、Ⅲ级组(32例)、Ⅳ级组(31例)3个亚组,选取同期30例健康体检者和30例射血分数减低的心力衰竭患者作为对照。所有入选者均经心脏超声心动图检查,并测定血浆和肽素、氨基末端脑钠肽前体(NT-ProBNP)等项目水平。结果 (1)HFNEF各亚组血浆和肽素与健康对照组对比,明显升高(P<0.05),且随心力衰竭程度加重而升高(P<0.05)。(2)HFNEF各亚组血浆NT-ProBNP水平与健康对照组对比,明显升高(P<0.05),且随心力衰竭程度加重而升高(P<0.05)。(3)随心力衰竭程度加重,HFNEF各亚组间超声心动图E/A值逐渐减小,HFNEF各亚组间比较差异有统计学意义(P<0.05)。(4)血浆和肽素水平与超声心动图E/A值呈负相关(r=-0.475,P<0.05),与血浆NT-ProBNP水平呈正相关(r=0.583,P<0.05)。结论血浆和肽素水平在HFNEF中明显升高,可作为HFNEF诊断及判断严重程度的客观指标。
