Abstract: | BACKGROUND: It remains unclear whether sirolimus-eluting stents (SES) have an advantage over bare metal stents (BMS) in patients on dialysis. METHODS AND RESULTS: Percutaneous coronary intervention (PCI) using SES was performed in 54 dialysis patients with 69 lesions. A control group for comparison comprised 54 consecutive dialysis patients with 58 lesions who underwent PCI using BMS. Angiographic and clinical follow-ups were scheduled at 9 months. After the procedure, minimum lumen diameter (MLD) was similar between the 2 groups. At follow-up, the SES group had a higher MLD than the BMS group (1.98+/-0.83 mm vs 1.50+/-0.78 mm, p<0.01). In-stent restenosis rate was lower in lesions treated with SES than in those with BMS (22% vs 40%, p=0.048). However, there was no significant difference between the 2 groups for in-segment restenosis (31% vs 43%, p=0.3). During follow-up, there was no significant difference in the incidence of death, myocardial infarction or target lesion revascularization (TLR) (14% vs 21%, p=0.4) between the SES and BMS groups. CONCLUSIONS: In this retrospective study, SES, in comparison with BMS, reduced in-stent restenosis in patients on dialysis. However, in-segment restenosis and TLR were not statistically different between lesions treated with SES and those with BMS. |
