摘要 目的探讨氯沙坦对冠心病冠状动脉介入诊疗患者肾功能的保护作用及机制。方法 221例接受冠状动脉造影(CAG)或经皮冠状动脉介入术治疗(PCI)的冠心病患者随机分为三组。对照组(72例)术前不服用氯沙坦;低剂量组(74例)及高剂量组(75例)术前1 d开始分别晨服氯沙坦50、100 mg,1次/d。分别于术前和术后24h检测各组血尿酸(SUA)、肌酐(Scr)、尿素氮(BUN)、肾素活性、血管紧张素Ⅱ(AngⅡ)及醛固酮水平,采用MDRD方法估算肾小球滤过率(eGFR);采用ELISA法检测血清和尿液中性粒细胞明胶酶相关脂质运载蛋白(NGAL)和半胱氨酸蛋白酶抑制物C(CysC)水平。记录对比剂急性肾损伤(CIAKI)发生率。随访90 d观察用药依从性并记录临床事件。结果三组共发生CIAKI 8例,其中对照组、高剂量组各2例,低剂量组4例。与对照组相比,低剂量组和高剂量组术后血SUA和BUN均降低(P均<0.01),呈剂量依赖性;对照组术后血Scr、血NGAL和血Cysc升高、eGFR降低(P均<0.05),低剂量组术后血CysC升高(P<0.05)。结论氯沙坦可降低冠心病患者介入诊疗术后血尿酸水平,改善肾功能,其机制可能与阻断肾素—血管紧张素系统、降低围手术期血尿酸水平有关。
