摘要 目的探究老年慢性心力衰竭患者血浆和肽素(copeptin)水平及临床意义。方法将150例老年慢性心力衰竭患者设为观察组,根据美国纽约心脏病协会(NYHA)分级分为Ⅱ级、Ⅲ级和Ⅳ级三个亚组;随访1年,根据随访期间有无心血管不良事件分为良好组和不良组。另选择50例健康志愿者作为对照组。检测各组左室射血分数(LVEF)、左室舒张末期内径(LVEDd)、血浆copeptin、N末端B型利钠肽原(NT-pro BNP)水平。结果观察组copeptin、NT-pro BNP、LVEDd水平显著高于对照组,LVEF水平显著低于对照组(均P<0.05);不同心功能分级亚组间copeptin、NT-pro BNP、LVEF、LVEDd比较差异显著(P<0.05),心功能分级越高,copeptin、NT-pro BNP、LVEDd水平越高,LVEF水平越低;不良组患者copeptin、NT-pro BNP、LVEDd水平显著高于良好组,而LVEF水平显著低于良好组(均P<0.05);Pearson相关分析显示,copeptin与NT-pro BNP、LVEDd呈显著正相关,与LVEF呈显著负相关(P<0.05)。结论 copeptin在老年慢性心力衰竭患者血浆高表达,可作为早期诊断、病情严重程度和预后判断的指标。
