1、2011年8月第49卷第24期·论著·卡维地洛对老年慢性心力衰竭患者心功能的影响王丽霞徐惠(浙江省诸暨市中医院内二科,浙江诸暨311800)【摘要】目的研究卡维地洛或美托洛尔对老年慢性心力衰竭患者心功能的改善作用及对血清肾上腺素受体自身抗体(Ot、131、132)的影响。方法将72例老年心衰患者随机分为A组和B组,在常规强心、利尿治疗的同时,分别应用卡维地洛和美托洛尔进行治疗,比较两组治疗前和治疗后6个月心脏超声指标和、p1、132受体自身抗体的变化。结果两组的LVEDD、LVEDV、LVSDV值明显降低,LVEF值显著升
2、高(P<0.05),且A组更优于B组(P<0.05),A组的抗抗体、抗B1抗体、抗p2抗体阳性率均较治疗前显著降低(P0.05o结论卡维地洛可有效改善心功能,提高心脏射血分数,改善心室重构,疗效优于美托洛尔,其机制可能与其持久地非选择性地阻断131、B2受体和血管壁Of.1受体,使其最大限度地降低过度激活的神经内分泌因子介导的心肌毒性作用有关。[关键词】心力衰竭;肾上腺素能;自身抗体【中图分类号】R541~61【文献标识码】A【文章编号】1673—9701(2011
