摘要 目的探讨外周血B型钠尿肽(BNP)、超敏C-反应蛋白(CRP)与老年慢性心力衰竭患者左心室重构的关系。方法以58例慢性心力衰竭患者(试验组)及20例心脏功能正常的健康体检者(对照组)作为研究对象,比较2组BNP、超敏CRP浓度变化。并应用心脏彩色超声心动图测定所有入选人群的左心室舒张末内径(LVDd)、左房内径(LAD)、左心室收缩末内径(LVDs)、左心室后壁厚度(LVPWT),室间隔厚度(IVST)、左心室射血分数(LVEF)等,利用以上数值根据公式计算左心室心肌重量指数(LVMI),讨论BNP与老年慢性心力衰竭患者左心室重构的关系。结果试验组血清BNP、超敏CRP明显高于对照组(P<0.01);试验组LVDd、LAD、IVST、LVPWT均显著高于对照组(P<0.05或<0.01)。试验组LVEF明显低于对照组(P<0.05),试验组LVMI显著高于健康对照组(P<0.01);BNP浓度与LVEF呈负相关(P<0.05),并与LVDd、LAD、IVST、LVPWT、E/A、LVMI、左心室结构及功能异常呈正相关(P<0.05或<0.01);与超敏CRP浓度呈正相关(P<0.05)。多因素逐步回归分析显示,BNP浓度水平升高是心力衰竭患者左心室重构的独立预测因素之一。结论慢性心力衰竭患者由于存在心脏病理及病理生理改变,使心脏发生结构的重构和非特异性炎性反应,致外周血BNP及超敏CRP浓度显著升高,并且与左心室重构程度密切相关。
