Comparison of long-term clinical outcome after sirolimus-eluting stent implantation in patients with and without hemodialysis.
Poor clinical outcomes for hemodialysis (HD) patients compared to non-HD patients after coronary intervention have been reported. Although coronary intervention using sirolimus-eluting stents (SESs) might be expected to reduce restenosis in HD patients, little is known about the efficacy of the SESs. The purpose of the present study was to compare the clinical and angiographic outcomes of HD patients with non-HD patients after SES implantation. The study population consisted of 170 consecutive patients (234 lesions) who had undergone successful coronary SES implantation. The patients were classified into 2 groups, an HD group (18 patients, 27 lesions) and a non-HD group (152 patients, 207 lesions). The incidence of any clinical event was significantly higher in the HD group than in the non-HD group (50.0% versus 12.5%, P < 0.0001). Target lesion revascularization was necessary in 6 patients (33.3%) in the HD group and in 7 patients (4.6%) in the non-HD group (P < 0.0001). The Cox proportional-hazards regression model on cardiac events identified HD patients (P = 0.0301, hazard ratio = 2.704) as an explanatory factor. Moreover, the Cox proportional-hazards regression model on target lesion revascularization identified HD (P = 0.0004, hazard ratio = 6.921) and in-stent re-stenosis lesion (P = 0.0293, hazard ratio = 3.323) as explanatory factors. The present study suggests that compared with non-HD patients, HD patients with coronary artery disease treated by SESs have a poorer clinical outcome.
