• 【摘要】目的    分析合并终末期肾病（ESRD）的冠状动脉粥样硬化性心脏病（冠心病）患者行冠状动脉旁路移植术(CABG)的早期临床效果及中远期随访结果。方法    收集2010年1月至2017年12月首都医科大学附属北京安贞医院30例需透析治疗的ESRD合并冠心病患者的临床资料，术前肌酐（665±262）μmol/L,肾小球滤过率（8±4）ml/(min·1.73 m2)；平均冠状动脉病变支数(3.1±0.8)支。其中行非体外循环CABG 28例、体外循环下CABG＋二尖瓣成形或置换各1例。分析患者的手术资料、围术期情况、出院用药并完成术后随访。结果    全部患者术后均使用连续肾脏替代透析治疗。平均完成冠状动脉吻合桥数(3.1±0.7)支。主动脉内球囊反搏使用率为33.3%(10/30)。围术期死亡率为10.0%(3/30)，死亡原因包括心功能衰竭2例和顽固性心室颤动1例。术后二次开胸止血率为6.7%(2/30)。围术期心房颤动发生率26.7%(8/30)，心肌梗死发生率为36.7%(11/30)。出院服用联合抗血小板药物治疗占85.2%(23/27)。术后成功随访25例，随访率为92.6%（25/27）；中位随访时间4(1，7)年，全因死亡率为12.0%(3/25)，其中心源性猝死1例，肺部疾病导致死亡2例；不良心脑血管事件发生率为20.0%（5/25）。结论    合并ESRD的冠心病患者行CABG的围术期风险较高，但中远期随访结果较为满意。

• 【Abstract】Objective    To analyze the early and long-term outcomes of coronary artery bypass grafting (CABG) in coronary atherosclerotic heart disease（CHD） patients with end-stage renal disease(ESRD). Methods    Clinical data of 30 ESRD patients who had CABG from January 2010 to December 2017 in Beijing Anzhen Hospital, Capital Medical University were analyzed; the mean creatinine level was （665±262）μmol/L; the mean glomerular filtration rate was （8±4）ml/(min·1.73 m2); the mean number of coronary artery lesions was (3.1±0.8). Twenty-eight patients had off-pump CABG; 1 patient had on-pump CABG plus mitral valvuloplasty; 1 patient had on-pump CABG plus mitral valve replacement. Surgical and perioperative records, discharge medication and follow-up data were analyzed. Results    All patients had continuous renal replacement therapy after surgery. The mean number of bypass grafts was (3.1±0.7). Intra-aortic balloon pump was used in 10 patients(33.3%). The perioperative mortality rate was 10.0%(3/30) including heart failure（2 cases） and ventricular fibrillation（1 case）. Two patients(6.7%) had reoperation for hemorrhage. Perioperative atrial fibrillation and myocardial infarction rates were 26.7%(8/30) and 36.7%(11/30), respectively. Twenty-three patients（85.2%） took antiplatelet drugs after discharge. Twenty-five patients（92.6%） were followed up for 4(1，7) years; the all-cause mortality rate was 12.0%(3/25) including sudden cardiac death（1 case） and pulmonary disease（2 cases）; the cardiovascular adverse event rate was 20.0%（5/25）. Conclusion    CABG procedure has a high risk in CHD patients with ESRD; the mid- and long-term outcomes are good.
