Abstract: | Objectives : We sought to determine if differences existed in in‐hospital outcomes, long‐term rates of target vessel revascularization (TVR), and/or long‐term mortality trends between patients with diabetes mellitus undergoing percutaneous coronary intervention (PCI) with either a drug‐eluting stent(s) (DES) or a bare metal stent(s) (BMS). Background : Short‐ and long‐term clinical outcomes of patients with diabetes mellitus undergoing PCI with DES versus BMS remain inconsistent between randomized‐controlled trials (RCTs) and observational studies. Methods : Data were collected prospectively on diabetics undergoing PCI with either DES or BMS from January 2000 to June 2008. Demographic information, medical histories, in‐hospital outcomes, and long‐term TVR and mortality trends were obtained for all patients. Results : A total of 1,319 patients were included in the study. Diabetics receiving DES had a significant reduction in index admission MACE compared to diabetics receiving BMS. Using multivariable adjustment, after a mean follow‐up of 2.5 years (maximum 5 years), diabetics who received DES had a 38% decreased risk of TVR compared to diabetics with BMS HR 0.62 (95% CI: 0.43–0.90)]; diabetics with DES had an insignificant adjusted improvement in long‐term survival compared to diabetics with BMS HR 0.72 (95% CI: 0.52–1.00)]. These long‐term survival and TVR rates were confirmed using propensity scoring. Conclusions : The use of DES when compared with BMS among diabetics undergoing PCI is associated with significant improvement in long‐term TVR, with an insignificant similar trend in all‐cause mortality. The long‐term results of this observational study are consistent with prior RCTs after adjusting for confounding variables. © 2010 Wiley‐Liss, Inc. |
