BACKGROUND: Few data are available on diabetic patients undergoing percutaneous coronary intervention (PCI) in the context of unprotected left main coronary artery (ULMCA) disease. The main goal of this study was to present the long-term relative benefits of using drug-eluting stent (DES) instead of bare-metal stent (BMS) for diabetic patients submitted to percutaneous ULMCA treatment in a large real world multicenter registry. METHODS: The GISE-SICI registry is a retrospective, observational multicenter registry promoted by the Italian Society of Invasive Cardiology in which 19 high-volume participating centers enrolled 1,453 consecutive patients who underwent PCI on ULMCA between January 2002 and December 2006. From the registry, a total of 398 consecutive patients with diabetes mellitus who underwent DES (n = 321) or BMS (n = 77) implantation were analyzed, with extensive multivariable adjustments. RESULTS: At 3-years, use of DES in diabetic patients resulted in no significant differences with respect to death (HR 0.56, 95% CIs 0.24-1.28), myocardial infarction (HR 0.82, 95% CIs 0.21-3.26), and the composite end-point of death or myocardial infarction (HR 0.56, 95% CIs 0.27-1.20). Conversely, DES were associated with significant reduction of target lesion revascularization (TLR, HR 0.33; 95% CIs 0.14-0.80, P = 0.001) rates. CONCLUSIONS: Patients presenting with ULMCA disease in the context of diabetes mellitus who are treated with stent-supported PCI have a significant reduction in the rate of TLR with no increased risk of death or myocardial infarction.
