摘要
目的探讨正常成年人血液中N端脑钠肽前体(NT-proBNP)的正常水平;研究心衰患者血液中NT-proBNP水平与心功能分级和左心室射血分数(LVEF)的关系,探讨NT-proBNP对心衰的诊断价值。方法选取2004年6月至2006年4月在北京医院门诊、急诊就诊和住院的心衰患者140例,正常对照组40例。心衰的诊断以临床症状、体征、心电图和超声心动检查为依据。使用Roche电化学发光免疫分析的原理检测对照组和心衰患者血中NT-proBNP的浓度。心功能分级按照纽约心脏病协会(NYHA)对心衰患者进行分级。结果受试正常人的参考水平低于国外人群;心衰患者NT-proBNP的浓度与心功能分级呈正相关;心衰患者的NT-proBNP浓度与LVEF呈负相关;不同病因造成的同级心衰中,急性心梗患者NT-proBNP最高,房颤组的NT-proBNP低。结论用NT-proBNP评价心功能状态具有客观性和灵敏性,对早期诊断心衰有帮助,应成为临床应用的常规检测指标。建议建立正常中国人的NT-proBNP参考范围。
