Angiographic and clinical outcomes in patients with versus without diabetes mellitus after revascularization with BioMime sirolimus-eluting stent

Drug-eluting stents (DES) significantly improved angiographic and clinical outcomes compared with bare-metal stents in patients with diabetes. The clinical effects of BioMime sirolimus-eluting stent (SES) in patients with diabetes have not been evaluated. Therefore, we compared the efficacy of BioMime DES in coronary artery disease (CAD) patients with versus without diabetes.This prospective analytical study compared angiographic in-segment late loss and clinical effectiveness of BioMime SES stents in treating patients with (patients: 77 and lesions: 83) versus without (patients: 154 and lesions: 162) diabetes. The purpose of this study was the comparison of angiographic in-segment late loss at 12 months. Major adverse cardiac events (MACEs) were also monitored as secondary outcomes 24 months after the index procedure.Of 231 patients enrolled in the study, the mean age was 63.3 years and 153 patients were male. Angiographic follow-up rate was 84.8% (patients: 196) and intravascular ultrasound (IVUS) follow-up rate was 67.9% (patients: 157) at 12 months. Diabetic patients were comparable to nondiabetic patients for 12-month in-segment late loss (0.01 ± 0.31 mm for the nondiabetes group versus 0.04 ± 0.11 mm for the diabetes group; P = 0.158; P < 0.05). At 24 months, MACEs, including death, myocardial infarction and ischemic-driven target lesion revascularization were not statistically different between the two treatment groups.BioMime SES stents in treating patients with diabetes were comparable in reducing angiographic restenosis at 12 months and MACEs at 24 months compared to nondiabetic patients with CAD.
