1、【摘要】目的:探讨慢性心衰患者血清脑利钠肽前体(NT-proBNP)水平与不同NYHA心功能分级、左室射血分数(LVEF)、左室舒张期末内径(LVEDd)的相关性。方法:83例心力衰竭住院患者,使用酶联免疫法测定其血清NT-proBNP水平,超声心动图测定LVEF及LVEDd,分析患者NT-proBNP水平与不同心功能分级及上述指标的相关性。结果:(1)不同NYHA心功能分级组患者血清NT-proBNP水平(pg/ml)差异有显著性[Ⅰ级:162.5(128.0,633.0),Ⅱ级:1202.5(587.0,2350.0),Ⅲ级:3374.0(2169.0,4442.0)
2、,Ⅳ:10403.5(7241.0,17697.0),P<0.05~<0.01],其水平与心功能分级呈正相关(r=0.797,P<0.0001);(2)NT-proBNP与LVEF呈负相关(r=-0.438,P<0.0001);(3)NT-proBNP与LVEDd呈正相关(r=0.437,P<0.0001)。结论:NT-proBNP测定是临床诊断心力衰竭的有效辅助方法之一,总体上可反映心力衰竭的严重程度。【关键词】心力衰竭,充血性;利钠肽,脑;心室功能,左 correlationbetweenserumNT-proBNPandcardiacfunctioninpatien
