Long-term clinical outcomes after sirolimus-eluting stent implantation in dialysis patients.

There is little information about long-term (> 1 year) outcomes after sirolimus-eluting stent (SES) implantation in dialysis patients. Percutaneous coronary intervention (PCI) using SES was performed in 63 dialysis patients with 77 lesions. A control group for comparison was composed of 45 consecutive dialysis patients with 62 lesions who received PCI using bare metal stents (BMS). Clinical follow-up duration was 21.7 +/- 8.4 months in the SES group and 32.1 +/- 9.2 months in the BMS group (P < 0.01). There was no significant difference in the in-segment restenosis rate (30% versus 40%, P = 0.20) between the 2 groups. The 3-year mortality (22.5% versus 22.2%, P = 0.75), myocardial infarction (3.8% versus 4.9%, P = 0.93), target lesion revascularization (24.7% versus 31.0%, P = 0.61), and stent thrombosis rates (3.8% versus 2.4%, P = 0.73) were not significantly different between the SES and BMS groups. Compared to BMS, SES do not improve long-term clinical outcomes in dialysis patients.
