Background : To date, it remains unknown whether different types of new‐generation drug‐eluting stents have a differential impact on long‐term outcomes in diabetic patients. Methods and Results : In this historical cohort study (two Italian centers), we analyzed 400 diabetic patients with 553 coronary lesions treated with new‐generation CoCr zotarolimus‐eluting stents (R‐ZES: 136 patients, 196 lesions) or everolimus‐eluting stents (EES: 264 patients, 357 lesions) between October 2006 and August 2012. Primary endpoint was the occurrence of major adverse cardiac events (MACE) over a 2‐year follow‐up period. MACE was defined as all‐cause mortality, any myocardial infarction (MI) and/or target lesion revascularization (TLR). Multivessel revascularization, intervention for restenotic lesion and use of intravascular ultrasound were significantly higher in the R‐ZES group, whereas small stent (≤2.5 mm) deployment was significantly higher in the EES group. At 2‐year follow‐up, there was no significant difference in occurrence of MACE (R‐ZES vs EES: 22.8% vs 18.9%, P = 0.39). Similarly, no significant differences were observed in the composite endpoint of all‐cause mortality/MI (10.0% vs 10.3%, P = 0.86) or TLR (12.4% vs 7.4%, P = 0.11). Adjustment for confounders and baseline propensity‐score matching did not alter the aforementioned associations. Conclusion : After 2 years of follow up similar outcomes (MACE, all‐cause mortality/MI, TLR) were observed in real‐world diabetic patients, including those with complex lesions and patient characteristics, treated with R‐ZES and EES. © 2015 Wiley Periodicals, Inc.
