摘要 目的探讨N端B型脑钠肽(NT-proBNP)检测对心脏病患者左心功能不全的诊断意义。方法对140例无左心功能不全症状或表现不典型的器质性心脏病患者,进行心电图、胸片、超声多普勒及NT-proBNP检测,并与50例无器质性心脏病患者作为正常对照进行比较。结果140例器质性心脏病患者中,39例(27.8%)各项辅助检查证实有左心功能不全,56例(40%)无左心功能不全,前者NT-proBNP均值>2 000 pg/mL,后者均值<400pg/mL,另45例(32.14%)介于400~2 000 pg/mL之间。结论NT-proBNP测定可显著提高无症状的器质性心脏病(400~2 000 pg/mL)左心功能不全的准确性,低值(<400 pg/mL)可排除,高值(>2 000 pg/mL)有诊断意义,但介于低值与高值之间的意义有待进一步探讨。
