摘要
目的 :探讨慢性心力衰竭 (心衰 )患者血清脑利钠肽 (BNP)水平变化及其临床意义。方法 :用酶联免疫吸附法 (ELISA)检测 72例慢性心衰患者 (心衰组 )和 30例健康成人 (对照组 )血清BNP 32浓度 ,并动态观察心功能分级 (NYHA)Ⅲ级、Ⅳ级患者治疗2wk后BNP 32水平变化。比较不同NYHA分级与不同病因的BNP水平差异 ,以及治疗前后的动态变化。结果 :(1)心衰组BNP水平 85 8.7±32 6 .9ng·L-1明显高于对照组 10 9.3± 37.6ng·L-1(P <0 .0 1)。心衰组和对照组的BNP水平的 95 %可信区间 (CI)分别为 781.9~ 935 .5ng·L-1和 95 .3~12 3.3ng·L-1,相互之间无交叉。 (2 )血清BNP水平对慢性心衰的诊断界值为 12 0ng·L-1时 ,其灵敏度和特异性分别为 10 0 %和 87%。 (3)NYHAⅡ级、Ⅲ级和Ⅳ级的BNP水平分别为 6 38.5± 2 2 4 .5、878.0±334.0和 10 4 5 .8± 5 85 .1ng·L-1(P <0 .0 1) ,BNP水平与NYHA分级呈正相关 (r =0 .818,P <0 .0 1) ,与原发病无相关性 (P >0 .0 5 )。 (4 )BNP水平较高的患者预后差 ,治疗后BNP水平下降者疗效较好 ,反之疗效差。结论 :BNP水平对慢性心衰患者的诊断、病情和治疗效果评估、预后判断具有重要临床意义。
