The aim of this study is to know whether CABG with complete revascularization and similar graft selection can provide equivalent long-term benefits for patients on and not on hemodialysis. Methods: Between 2004 and 2018, 746 patients underwent isolated CABG, of which 106 were on hemodialysis. Propensity matching on baseline characteristics, graft types and on/off-pump CABG was performed to compare clinical outcomes between patients on (n = 102) and not on (n = 102) hemodialysis. Results: Complete revascularization was achieved in all patients. The mean follow-up was 112.5 ± 46.6 months. Off-pump rates (hemodialysis vs non-hemodialysis, 93/102 vs 94/102, p > 0.999) and graft selections (distal anastomoses: 3.7 ± 1.4 vs 3.8 ± 1.5, p = 0.377, ITA grafts: 1.4 ± 0.6 vs 1.5 ± 0.6, p = 0.560, arterial grafts: 1.9 ± 0.9 vs 2.0 ± 0.8, p = 0.658, vein grafts: 0.69 ± 0.63 vs 0.65 ± 0.70, p = 0.513) were well balanced between the groups. Hospital mortality was higher in patients on hemodialysis than in those not on hemodialysis (5/102 vs 1/102, p = 0.212). The Kaplan-Meier analysis revealed that cardiac death (without non-cardiac causes) was significantly more common in patients on hemodialysis than in those not on hemodialysis (p = 0.018). However, there were no significant differences in deaths due to ischemic heart disease (p = 0.327), repeated revascularization (p = 0.542), myocardial infarction (p = 0.783), and heart failure requiring admission (p = 0.371). Conclusion: CABG with complete revascularization and similar graft selection provides equivalent long-term benefits with regard to the prevention of adverse cardiac events due to ischemic heart disease in patients on and not on hemodialysis.展开更多
