【摘要】 目的 探討血漿腦鈉素(BNP)水平對(duì)心源性呼吸困難的診斷價(jià)值。方法 采用特異性放射免疫法測(cè)定慢性心力衰竭(CHF)引起的呼吸困難患者(n=52)和非CHF引起呼吸困難患者(n=30),以及健康志愿者(正常對(duì)照組,n=28)血漿BNP濃度,并進(jìn)行組間比較。結(jié)果 CHF組BNP濃度均顯著高于非CHF組及正常對(duì)照組[(649.80±141.72)pg/mL比(59.08±18.60)pg/mL和(65.20±16.32)pg/mL,P lt;0.05],而非CHF組與正常對(duì)照組BNP濃度無(wú)顯著差異,不同NYHA心功能分級(jí)患者的血漿BNP濃度隨心功能級(jí)別增加而顯著增高,CHF患者血漿BNP濃度與左室射血分?jǐn)?shù)(LEVF)水平呈顯著負(fù)相關(guān)(r=-0.673,P lt;0.001)。受試者工作特征曲線(ROC曲線)下面積為0.91(0.88~0.98,P lt;0.001),最佳界值(206 pg/mL)時(shí)的敏感性、特異性、陽(yáng)性預(yù)測(cè)值和陰性預(yù)測(cè)值分別為87.2%,86.8%,84.2%和91.8%。結(jié)論 血漿BNP是診斷心源性呼吸困難的一項(xiàng)很有價(jià)值的指標(biāo)。
