[摘要] 目的 研究强化阿托伐他汀钙治疗对经皮冠状动脉介入术后造影剂肾病的干预作用,并探讨其作用机制及其发生的相关因素。 方法 入选104例冠心病患者,根据围术期他汀治疗方案的不同,将其分为强化他汀治疗组(A组,54例)、常规他汀治疗组(B组,50例),所有患者经皮冠状动脉介入治疗术前及术后1 d均检测超敏C反应蛋白(hs-CRP)、胱抑素C(Cys-C)和血肌酐(Scr)水平。 结果 术前两组患者Scr、Cys-C、hs-CRP水平比较差异无统计学意义(P > 0.05),术后第1天A组患者Cys-C、hs-CRP、Scr水平均显著低于B组(P < 0.05)。术后A组有1例(1.85%)患者出现造影剂肾病,B组有4例(8.00%)患者出现造影剂肾病,差异有高度统计学意义(P < 0.01)。经过Logistic回归分析显示,年龄、术前Cys-C、术前hs-CRP、高血压、糖尿病为造影剂肾病发生的危险因素。 结论 阿托伐他汀钙早期干预对经皮冠状动脉介入术后患者的肾功能具有保护作用;年龄、术前Cys-C、hs-CRP、高血压、糖尿病等为造影剂肾病发生的独立危险因素。

[Abstract] Objective To explore the effect of high-dose Atorvastatin Calcium in preventing radiographic contrast nephropathy after percutaneous coronary intervention and to discuss its mechanism and related risk factors. Methods One hundred and four cases of patients with coronary heart disease were selected, according to the differences of statins therapeutic regimen in perioperative period, they were divided into intensive statin group (group A, n = 54) and conventional statin group (group B, n = 50). The serum creatinine (Scr), cystain C (Cys-C), high sensitivity C-reactive protein (hs-CRP) of all patients were respectively calculated before percutaneous coronary intervention and one day after percutaneous coronary intervention. Results ①Before operation, the differences of Scr, Cys-C and hs-CRP between two groups were not statistically significant (P > 0.05). On the first day after operation, the levels of Cys-C, hs-CRP, and Scr of group A were significantly lower than those of group B (P < 0.05). After operation, there was one patient (1.85%) with contrast induced nephropathy in group A, 4 patients (8.00%) with contrast induced nephropathy in group B, the difference was statistically significant (P < 0.01). Logistic analysis showed that age, preoperative Cys-C, hs-CRP, hypertension, diabetes were the risk factors of contrast induced nephropathy. Conclusion Early intervention of Atorvastatin Calcium has a protective effect on renal function of patients with percutaneous coronary intervention. Age, preoperative Cys-C, hs-CRP, hypertension and diabetes are the independent risk factors for radiographic contrast nephropathy.

近年来,随着疾病谱的变化,冠心病业已成为威胁广大人民群众生命的主要疾病。自20世纪70年代以来,经皮冠状动脉介入治疗(PCI)取得了长足的进步和发展,疗效不断提高,治疗范围逐渐扩大,安全性也不断提高,大大减少了病死率。然而,PCI随之带来的重要并发症之一——造影剂肾病已成为临床出现肾功能衰竭的一个很重要的原因[1]。自他汀问世以来,其对冠心病的治疗预防发生了颠覆性的革命,发表于2007年JACC上的他汀与冠心病的研究表明,如果在围术期增加他汀剂量,进行他汀强化治疗,可以明显减少围术期再发心血管事件及造影剂肾病的发生[2]。然而,由于ARMYDA-ACS样本数量较小,缺乏大规模多中心的研究,因此国内外关于强化他汀对造影剂肾病的预防及治疗效果仍有争议。本研究旨在对阿托伐他汀强化治疗预防PCI术后造影剂肾病的临床效果做出评价。……p>
