目的:通过检测房间隔缺损血浆氮末端脑钠肽前体(N-terminal pro-brain natriureticpeptide, NT-proBNP)浓度,研究NT-proBNP与肺动脉高压关系,为临床评估先心病相关性肺动脉高压的程度提供参考.方法:入选2010年6月~2012年10月我院心内科导管室房间隔缺损患者80例为实验组,男40例,女40例,年龄18~49岁.另选20例健康正常人作为对照组,年龄18~49岁.依据肺动脉平均压(mPAP)分为5组:正常PAH组(n=20)、轻度PAH组(n=20)、中度PAH组(n=20)、重度PAH组(n=20),正常对照组(n=20).所有患者均行右心导管检查,测右心房、右心室压力、肺动脉收缩压(SPAP)、肺动脉平均压(MPAP)、全肺阻力(PVR).采用电化学发光法测定患者右心导管检查前血浆NT-proBNP浓度,分析其与肺动脉压力的相关性及在诊断不同程度肺动脉高压时的敏感性和特异性.
