Long-Term Clinical Outcomes and Stent Thrombosis of Sirolimus-Eluting Versus Bare Metal Stents in Patients with End-Stage Renal Disease: Results of Korean Multicenter Angioplasty Team (KOMATE) Registry.

Background: There are still controversies about long-term clinical outcomes of sirolimus-eluting stents (SES) versus bare metal stents (BMS) implantation in patients with end-stage renal diseases (ESRD). Objective: To compare long-term outcomes in patients with (ESRD) following SES versus BMS implantation. Methods: Between March 2003 and July 2005, a total of 54 patients (80 lesions) with ESRD undergoing SES implantation [SES-ESRD] were enrolled and compared with 51 patients (54 lesions) with ESRD receiving BMS during the same periods [BMS-ESRD] in the Korean Multicenter Angioplasty Team Registry. The primary outcome was the composite of death, myocardial infarction (MI), or any stent thrombosis (ST) according to the Academic Research Consortium definition during a 3-year follow-up. Results: The cumulative 3-year rate of composite of death, MI, or ST of the SES-ESRD group (24%) was nearly similar with that of the BMS-ESRD group (24%, P = 1.000). The 3-year rates of death (26% vs. 24%, P = 0.824) or MACE (37% vs. 43%, P = 0.331) in the SES-ESRD did not differ significantly from those in the BMS-ESRD. However, the SES-ESRD showed a sustained lower 3-year TVR rate (9%), compared with BMS-ESRD (24%, P = 0.042). The rate of any ST in SES-ESRD was not significantly higher than that in the BMS-ESRD (17% vs. 14%, P = 0.788). There was no significant difference in the rate of late or very late ST between SES-ESRD (15%) versus BMS-ESRD group (10%, P = 0.557). Conclusions: SES did not increase the risks for death, MI, or any ST in patients with ESRD during the long-term follow-up, compared with BMS. [ABSTRACT FROM AUTHOR]
