摘要 目的 探讨心力衰竭(HF)患者N末端B型脑钠钛前体(NT-proBNP)及血浆肌酸激酶同工酶(CK-MB)与肌酸激酶(CK)比值(B/K)的动态变化及临床意义。方法用Staus FirstTMNT-proBNP测定仪快速测定85例不同病因所致的HF患者和50例同期非心血管病对照组患者的NT—proBNP及血浆CK-MB与CK的比值(B/K)。结果HF患者NT-proBNP水平较对照组升高,有统计学意义(P〈0.05);各NYHA分级中CK-MB、CK均在正常范围;而NT.proBNP随心功能不全的加重逐渐升高,心功能Ⅰ~Ⅳ级患者组各组间血浆NT-proBNP差异均有统计学意义(P〈0.05);心功能不全Ⅲ、Ⅳ级患者B/K比值较Ⅰ、Ⅱ级、对照有统计学意义(P〈0.05)。ROC曲线表明:NT-proBNP曲线下面积为0.938,若选取NT—proBNP188pg/ml作为心衰诊断的临界值,敏感性为88.2%,特异性为84%,说明NT-proBNP对HF有较高的诊断效率。结论NT.proBNP检测可作为HF急诊生化项目,可与B/K比值作为HF早期预测及中晚期预后指标。
