目的:观察冠状动脉介入术后患者肾功能变化情况、CIN发生率及其相关危险因素。方法:选择从2009年12月至2010年3月在新疆维吾尔自治区人民医院心内科接受冠状动脉介入术的患者131人,测定介入术前5天内任何一天和术后48小时的Scr,分析CIN危险因素。结果:131例患者中有8例发生CIN,发病率为6.1%,Logistic多因素回归分析均显示糖尿病、年龄大于70岁、LVEF小于45%是CIN发生的独立危险因素。结论:糖尿病、LVEF<45%、年龄>70岁是CIN的独立危险因素。
Objective: To observe the changes of renal function, the incidence of CIN and the related risk factors in patients after coronary intervention. Methods: From December 2009 to March 2010 in the People’s Hospital of Xinjiang Uygur Autonomous Region, patients undergoing coronary intervention in 131 patients were measured at any time within 5 days before intervention and after 48 hours of Scr analysis of CIN risk factor. Results: CIN was found in 8 out of 131 cases and the incidence was 6.1%. Logistic regression analysis showed that diabetes mellitus, age over 70 years old, and LVEF less than 45% were independent risk factors of CIN. Conclusion: Diabetes, LVEF <45%, and age> 70 years old are independent risk factors for CIN.
