Impact of diabetes mellitus on angiographic and clinical outcomes after early generation drug-eluting stent implantation

A relationship between coronary artery disease and diabetes has been established. Moreover, for patients with coronary artery disease, diabetes has long been considered a poor prognostic factor for percutaneous coronary intervention (PCI) using bare-metal stents or drug-eluting stents (DES). Patients with diabetes have an increased risk of mortality and repeat revascularization compared with nondiabetic patients after PCI. However, the very long-term impact of diabetes after early generation DES is still uncertain. In this study, we evaluate a recent publication, which assessed the angiographic and clinical outcomes of patients with diabetes versus nondiabetic patients after PCI using early generation DES.
