倾向性得分匹配分析认为ACEI/ ARB类药物可增加对比剂急性肾损伤的发生率

2013-07-01 MedSci MedSci原创

血管紧张素转换酶(ACE)抑制剂和血管紧张素受体拮抗剂(ARB)在对比剂急性肾损伤(AKI)的病理生理学上的作用是有争议的,且现有的文献也是相互矛盾的。

背景:血管紧张素转换酶(ACE)抑制剂和血管紧张素受体拮抗剂(ARB)在对比剂急性肾损伤(AKI)的病理生理学上的作用是有争议的,且现有的文献也是相互矛盾的。

研究设计:一项回顾性倾向得分匹配研究,分析ACE抑制剂/ARB疗法对造影剂导致AKI发展的效果。

地点及受试者:使用倾向得分匹配,在11447例接受冠脉血管造影(CAG)或经皮冠状动脉介入治疗的患者中,对符合纳入标准的1322 例接受ACE抑制剂/ARB的受试者和5299例未接受者进行配对分析。

预测因素:基于处方使用的ACE抑制剂/ARB和造影剂导致AKI的危险因素。

结局指标:造影剂导致AKI的发生率。采用AKIN的标准定义造影剂导致AKI:在暴露造影剂48小时内血清肌酐水平绝对增加≥ 0.3 mg/dL或从基线值相对增加≥50%。

指标:基线血清肌酐、血红蛋白、白蛋白水平;造影剂的量;术前药物治疗及CAG后的血清肌酐水平。

结果:64%接受CAG的患者被处方以ACE抑制剂/ ARB治疗。在倾向性得分匹配后,ACE抑制剂/ARB使用者造影剂导致AKI的发病率增加(11.4%vs.6.3%,P<0.001)。在多元分析中,非匹配队列中使用ACE抑制剂/ ARB类药物仍然是造影剂导致AKI的一个独立的、显著的预测因子(OR,1.39;95%CI,1.10-1.76;P = 0.06)。在匹配的队列中,ACE抑制剂/ ARB类药物的使用也与造影剂导致AKI较高的OR值(校正后)相关(OR,1.43;95%CI,1.06-1.94;P = 0.02)。

局限性:在单一的中心进行的回顾性研究。

结论:在CAG过程中应用ACE抑制剂/  ARB类药物可增加造影剂导致的急性肾损伤的发生率。仍需要进一步的随机对照研究来确认ACE抑制剂/ARB疗法对造影剂导致的AKI发展的作用。
