摘要
目的评价老年慢性心力衰竭(心衰)患者肾小球滤过功能的变化及卡维地洛对老年慢性心衰患者肾功能的影响。方法入选老年慢性心衰患者47例(慢性心衰组),健康体格检查的非慢性心衰患者22例(非慢性心衰组),分别检测血尿酸(SUA)、血肌酐(Scr),C-G法计算肾小球滤过率(GFR),确定显性肾功能不全(ORI)、隐匿性肾功能不全(CRI)、总肾功能不全(TRI)的发生率。慢性心衰组患者再随机分为卡维地洛组和非卡维地洛组,观察卡维地洛治疗3个月后的左室舒张末内径(LVEDD)、左室射血分数(LVEF)及肾小球滤过功能变化。结果慢性心衰组ORI和TRI发生率均高于非慢性心衰组(ORI分别为55.3%和22.7%,x=6.43,P<0.05;TRI分别为80.9%和40.9%,x2=11.01,P<0.01),但CRI发生率的差异统计学意义(25.5%和18.1%,x2=0.45,P>0.05);慢性心衰组SUA、Scr高于非慢性心衰组[SUA分别为(472.8±100.2)和(415.3±71.4) mmol/L,P<0.05;Scr分别为(150.7±68.0)和(108.5±43.2)mmol/L,P<0.01],GFR低于非慢性心衰组[分别为(42.9±20.7)和(59.3±30.1)ml/min,P<0.05)];与治疗前比较,卡维地洛组治疗3个月后的SUA[(407.5±57.7)mmol/L和(476.4±85.2)mmol/L,P<0.013、Scr[(113.5±55.4) mmol/L和(152.0±74.6)mmol/L,P<0.01]均显著下降,GFR升高[(57.9±23.7)ml/min和(45.0±22.6)ml/min,P<0.01];治疗3个月后,卡维地洛组SUA、Scr均显著低于同期的非卡维地洛组(均为P<0.05),GFR高于非卡维地洛组(P<0.01)。结论老年慢性心衰患者肾小球滤过功能下降。在充分抗心衰治疗的基础上,加用卡维地洛可以改善慢性心衰患者的肾小球滤过功能。
