摘要 目的探讨血浆B型钠尿肽(BNP)浓度对心功能的评价作用及其在诊断充血性心力衰竭(CHF)中的临床应用。方法采用化学发光微粒子酶免疫分析法测定92例CHF患者、45名正常对照者血浆BNP浓度。依据美国纽约心脏病协会(NYHA)分级方案对心力衰竭患者进行心功能分级。结果CHF组血清BNP浓度为(376.2±153.5)pg/mL,明显高于对照组[(16.2±9.7)pg/mL](P<0.05)。CHF组NYHA分级Ⅰ级血浆BNP浓度为(23.5±10.6)pg/mL、Ⅱ级为(106.8±85.1)pg/mL、Ⅲ级为(430.1±198.6)pg/mL、Ⅳ级为(782.5±263.2)pg/mL,各组间比较差异均有统计学意义(P<0.05)。结论CHF患者血浆BNP水平随着心力衰竭严重程度的增加而升高。BNP可以客观准确评价心功能,可以作为临床诊断CHF的实验室指标之一。
