摘要 目的探讨血浆脑钠肽(BNP)浓度的检测对呼吸困难患者的临床意义。方法2004年9月至2005年10月有呼吸困难患者63例。左心衰竭组30例。非心源性呼吸困难组23例,其中肺源性呼吸困难19例。另统计合并肺源性心脏病的慢性肺源性呼吸困难10例。均经干式快速免疫荧光法定量分析检测BNP。结果(1)血浆BNP水平在左心衰竭组及非心源性呼吸困难组分别为(1165.0±1128.3)pg/ml、(49.3±44.6)pg/ml(P<0.01),(2)左心衰患者心功能Ⅳ级、Ⅲ级、Ⅱ级组血浆BNP(pg/ml)水平分别是1702.8±649.3、607.9±344.1、108.8±101.1,两两相比均P<0.01,(3)肺源性呼吸困难患者合并肺源性心脏病与不合并肺源性心脏病组血浆BNP浓度分别为(504.9±500.9)pg/ml、(54.5±46.4)pg/ml(P<0,05),(4)心源性呼吸困难组与合并肺源性心脏病的肺源性呼吸困难组比较,P>0.05。结论呼吸困难患者测定血浆BNP对鉴别左心衰竭与非心源性呼吸困难有重要价值。血BNP水平随NYHA心功能分级程度的加重显著增高。血浆BNP浓度可作为一项慢性肺源性呼吸困难是否合并肺源性心脏病早期诊断的指标。肺源性心脏病患者与左心衰竭患者比较血浆BNP水平无显著差异。
