Abstract
Even in the drug-eluting stent era, adverse cardiac events, including restenosis after percutaneous coronary intervention (PCI), have been more frequently seen in patients on hemodialysis (HD) than in non-HD patients. The objective of this study was to compare the sirolimus-eluting stent (SES) and everolimus-eluting stent (EES) for prevention of adverse cardiac events, including restenosis, in HD patients. A total of 100 consecutive patients on HD who underwent PCI were enrolled and randomly assigned to receive SES or EES. Although there was no difference between the 2 groups in baseline patient and lesion characteristics, the angiographic restenosis rate at 8-month follow-up was 21.2% in the SES group and 8.7% in the EES group (P = 0.041). Significant differences were also seen in % diameter stenosis (%DS), minimal lumen diameter, and late lumen loss at 8-month follow-up (P = 0.0024, P = 0.0040, and P = 0.033, respectively). During the 1-year follow-up, major adverse cardiac events occurred in 11 (22.0%) patients in the SES group and in 5 (10.0%) patients in the EES group (P = 0.10). The use of EES was as safe as that of SES. Moreover, EES significantly prevented restenosis in patients on maintenance HD compared with SES.
