Background Accelerated atherosclerosis is a major risk for long-term survivors receiving hemodialysis (HD), with coronary events being the leading cause of mortality. Methods and Results A total of 88 consecutive patients on HD (121 lesions) who underwent percutaneous coronary intervention (PCI) with sirolimus-eluting stents (SES) were compared with 78 patients on HD (95 lesions) who received bare metal stents (BMS) in the preceding 1 year. The primary endpoint was angiographic restenosis defined as ≥50% diameter stenosis at 6-8 months follow-up after PCI. The angiographic restenosis rate at follow-up was 22.2% in the SES group and 24.4% in the BMS group. No difference was detected in the restenosis rate between the 2 groups (p=0.73). When including both HD and non-HD patients, the independent predictors for restenosis after SES implantation were treatment with HD (hazard ratio (HR) 3.12; 95% confidence interval (CI) 1.23-7.95; p=0.016), incidence of hyperlipidemia (HR 3.93; 95%CI 1.12-13.7; p=0.032), coronary calcification (HR 2.78; 95%CI 1.12-6.91; p=0.027), and implantation of multi-stents (HR 4.14; 95%CI 1.70-10.1; p=0.0017). Conclusions Even if treated with SES, patients with end-stage renal failure on HD are at high risk of restenosis after PCI.
