[摘要] 目的 分析血浆BNP针对不同类型老年心力衰竭患者用以预测急性失代偿心衰(ADHF)的价值。 方法 选择2015年6月～2016年6月期间在我院心内科住院的患者228例(含心功能正常者40例)作为研究对象，将心衰患者按照心脏超声结果分为左室射血分数降低心衰(HFrEF)组94例和左室射血分数正常心衰(HFpEF)组94例，分别测定其初始血浆BNP值。 结果 心衰患者BNP水平均显著高于心功能正常者(P<0.05)，针对心衰患者而言，HFrEF组血浆BNP水平显著高于HFpEF组。半年随访过程中，两组患者均未发生死亡，HFrEF组因ADHF再次入院30例(31.91%)，HFpEF组因ADHF再次入院31例(32.98%)，(P>0.05)。 结论 心衰患者失代偿前BNP升高，BNP升高可作为预测ADHF的重要指标，具有极大的推广应用价值。

    [Abstract] Objective To explore and analyze the value of plasma BNP in predicting acute decompensated heart failure (ADHF) in patients with different types of elderly heart failure. Methods A total of 228 patients(including patients with normal heart function) in our hospital from June 2015 to June 2016 were enrolled in the study. Heart failure patients were divided into heart failure with reduced ejection fraction (HFrEF) group (n=94) and heart failure without reduced ejection fraction (HFpEF) group (n=94) ......
