摘要 目的探讨血清脑钠肽(BNP)水平变化在慢性心力衰竭患者的临床诊断中的意义.方法用免疫荧光定量测定方法检测40例慢性心力衰竭患者(心力衰竭组)和20例无症状性心力衰竭患者(无症状性心力衰竭组)的血清脑钠肽-32水平,并以20例健康成人作为正常对照组.结果①心力衰竭组、无症状性心力衰竭组和正常对照组的血清脑钠肽-32水平分别为(867.5±310)ng/L、(429.3±138.8)ng/L和(107.3±36.6)ng/L,3组间两两比较差异均有显著性(P均<0.01);心力衰竭组、无症状性心力衰竭组和正常对照组的血清脑钠肽-32水平的95%可信区间分别为788.7~932.5ng/L、370~515.3ng/L和94.2~121.2ng/L相互之间无交叉.②血清脑钠肽-32水平对心力衰竭的诊断界值为120ng/L时,敏感性和特异性分别为100%和87.6%.③心功能(NYHA)Ⅰ级、Ⅱ级、Ⅲ级和Ⅳ级的血清脑钠肽-32水平分别为(437.0±135.8)ng/L、(629.3±238.4)ng/L、(891.2±318.5)ng/L和(1029.1±576.8)ng/L,各级间差异有显著性(P均<0.01);血清脑钠肽-32水平与NYHA分级呈正相关(r=0.823,P<0.01),与原发病无相关(P>0.05).结论血清脑钠肽水平在慢性心力衰竭患者的诊断中具有重要临床意义.
