Cardiovascular disease is the leading cause of death in patients who have chronic kidney disease or end-stage renal disease and are undergoing hemodialysis. Chronic kidney disease is a recognized risk factor for premature atherosclerosis. Unfortunately, most major randomized clinical trials that form the basis for evidence-based use of revascularization procedures exclude patients who have renal insufficiency. Retrospective, observational studies suggest that patients with end-stage renal disease and severe coronary occlusive disease have a lower risk of death if they undergo coronary revascularization rather than medical therapy alone. Due to a lack of prospective studies, however, the relative merits of percutaneous versus surgical revascularization are merely a matter of opinion. Several small, retrospective studies have shown that coronary artery bypass grafting is associated with higher procedural death but better long-term survival than is percutaneous coronary intervention. This difference appears to result from poor long-term results of percutaneous coronary intervention in patients who have chronic kidney disease or end-stage renal disease.Because randomized trials comparing percutaneous coronary intervention and coronary artery bypass grafting have included patients undergoing balloon angioplasty and placement of bare-metal stents, their conclusions are suspect in the era of drug-eluting stents. In this review, we discuss different revascularization options for patients with chronic kidney disease, the outcomes of revascularization procedures, and the risk factors for adverse outcomes.
心血管疾病是慢性肾脏病或终末期肾病且正在接受血液透析患者的主要死因。慢性肾脏病是公认的过早发生动脉粥样硬化的危险因素。不幸的是,构成基于循证使用血运重建术基础的大多数主要随机临床试验都将肾功能不全患者排除在外。回顾性观察研究表明,终末期肾病和严重冠状动脉闭塞性疾病患者接受冠状动脉血运重建而非单纯药物治疗时,死亡风险较低。然而,由于缺乏前瞻性研究,经皮血运重建与外科血运重建的相对优点只是一个观点问题。几项小型回顾性研究表明,冠状动脉旁路移植术与较高的手术死亡率相关,但与经皮冠状动脉介入治疗相比,长期生存率更高。这种差异似乎是由于慢性肾脏病或终末期肾病患者经皮冠状动脉介入治疗的长期效果较差所致。由于比较经皮冠状动脉介入治疗和冠状动脉旁路移植术的随机试验纳入了接受球囊血管成形术和裸金属支架置入术的患者,在药物洗脱支架时代,其结论值得怀疑。在本综述中,我们讨论了慢性肾脏病患者的不同血运重建选择、血运重建术的结果以及不良结局的危险因素。
