Coronary stent restenosis, which emerges in late periods after implantation, has not been completely abolished. Our aim was to investigate the restenosis rates of Ephesos coronary stents. In all, 96 patients (66 men) with 135 Ephesos coronary stents were included. Control angiograms were performed after 160 +/- 60 days. Quantitative coronary analysis was performed during the procedure and control angiogram. The stents were divided into 2 groups according to the presence or absence of restenosis. Groups were compared with clinical and angiographic variables. Restenosis was observed in 31 (23%) of 135 stents. Preprocedure percent diameter stenosis was higher (P = .02), whereas minimum lumen diameter ( P = .02), mean age (P < .001), and hypertension incidence ( P = .043) was less, and there was a trend toward smaller stent size ( P = .054) in the restenosis group. By multivariate analysis, age <50 years (P < .001) and stent size <3.0 mm (P = .016) were independent predictors of restenosis. Ephesos coronary stents seems to have acceptable restenosis rates.
