摘要
目的观察血管紧张素转换酶抑制剂(ACEI)对单侧动脉粥样硬化性肾动脉狭窄(ARAS)患者肾功能的影响。方法结合临床表现及肾动脉造影结果诊断单侧ARAS患者共49例,分为ACEI组20例与对照组29例。记录基础血压,检测Ser、BUN、Alb,以MDRD公式计算估计肾小球滤过率(eGFR),行肾动脉彩超检查测量肾脏阻力指数(RI)。每月测量血压,每6个月复查Scr、Urea、Alb并计算eGFR,观察两组患者随访期间肾功能变化。结果两组患者试验前一般临床资料元显著性差异。平均随访9.9个月,随访期间两组血压均无明显变化(P>0.05)。与试验前比,对照组eGFR无明显变化[(74.5±18.3)ml·min-1·(1.73m2)-1比(73.2±15.7)ml·min-1·(1.73m2)-1,P>0.05];而ACEI组eGFR下降明显[(69.3±14.6)ml·min-1·(1.732)-1比(63.5±16.4)ml·min-1·(1.73m2)-1,P<0.01]。观察结束时,ACEI组eGFR低于对照组[(63.5±16.4)ml·min-1·(1.73m2)-1比(73.2±15.7)ml·min-1·(1.73m2)-1,P<0.05]。ACEI组eGFR下降率(△eGFR%)明显高于对照组(-9.1%±6.8%比-0.6%±10.7%,P<0.01)。Pearson相关检验显示,基础eGFR、对侧肾脏RI与△eGFR%显著相关(r分别为0.583、-0.668,P<0.01)。结论对于单侧ARAS患者,当基础肾功能受损时,应用ACEI可能会导致肾功能下降,故应用时宜慎重,并定期监测肾功能。
