Diabetes mellitus has worse outcome after percutaneous coronary intervention.We assessed stent thrombosis (ST), major adverse cardiac events (MACE), and major bleeding rates at 1 year after implantation of sirolimus-eluting stents (SES) in patients with diabetes mellitus in a large multicenter registry.From May 2006 to April 2008, 15,147 unselected consecutive patients were enrolled at 320 centers in 56 countries in a prospective, observational registry after implantation of1 SES. Source data were verified in 20% randomly chosen patients at>100 sites. Adverse events were adjudicated by an independent Clinical Event Committee.Complete follow-up at 1 year was obtained in 13,693 (92%) patients, 4,577 (30%) of whom were diabetics. Within diabetics, 1,238 (9%) were insulin-treated diabetics (ITD). Diabetics were older (64 vs. 62 years, P<0.001), with higher incidence of major coronary risk factors, co-morbidities, and triple-vessel coronary artery disease. Coronary lesions had smaller reference vessel diameter (2.880.46 vs. 2.930.45 mm, P<0.001) and were more often heavily calcified (26.1% vs. 22.6%, P<0.001). At 1 year, diabetics had higher MACE rate (6.8% vs. 3.9%, P<0.001) driven by ITD (10.6% vs. 5.5%, P<0.001). Finally, diabetics had significant increase in ST (1.7% vs. 0.7%, P<0.001), principally owing to ITD (3.4% vs. 1.1%, P<0.001). There was an overall low risk of major bleeding during follow-up, without significant difference among subgroups.In the e-SELECT registry, diabetics represented 30% of patients undergoing SES implantation and had significantly more co-morbidities and complex coronary lesions. Although 1-year follow-up documented good overall outcome in diabetics, higher ST and MACE rates were observed, mainly driven by ITD. 2015 Wiley Periodicals, Inc.
