The aim of this study was to examine outcomes subsequent to implantation of drug-eluting stents (DESs) and bare-metal stents (BMSs) in patients with diabetes. From January 2002 to June 2005, data from all percutaneous coronary interventions performed in Western Denmark were prospectively recorded. A total of 1,423 consecutive diabetic patients treated with stent implantation (2,094 lesions) were followed up for 15 months. Of these, 871 patients (1,180 lesions) were treated with a BMS, and 552 patients (914 lesions) were treated with a DES. Dual antiplatelet therapy was recommended for 12 months in both treatment groups. Data for death and myocardial infarction (MI) were ascertained from national health care databases. Use of DESs was not associated with increased risk of definite stent thrombosis (adjusted relative risk [RR] 0.76, 95% confidence interval [CI] 0.10 to 3.26) or MI (adjusted RR 0.90, 95% CI 0.53 to 1.52). In the DES group compared with the BMS group, adjusted RRs of target-lesion revascularization (adjusted RR 0.48, 95% CI 0.33 to 0.71), total mortality (adjusted RR 0.66, 95% CI 0.44 to 0.99), and cardiac mortality (adjusted RR 0.53, 95% CI 0.31 to 0.90) decreased by 52%, 34%, and 47%, respectively. In conclusion, use of DESs reduced target-lesion revascularization in diabetic patients receiving routine clinical care. This result was obtained without increased risk of death, stent thrombosis, or MI.
