    Abstract:
    OBJECTIVES: The goal of this study was to demonstrate superiority of sirolimus-eluting stents (SES) over bare-metal stents (BMS) and of abciximab over no abciximab in primary percutaneous coronary intervention (PCI). BACKGROUND: Drug-eluting stents (DES) are increasingly used in primary PCI, but the recommendations for use in primary PCI are based on a few randomized controlled trials with selected patients. The usefulness of abciximab in primary PCI is not established. METHODS: Nine hundred seven patients referred to the Catharina Hospital were randomized to SES or BMS, and to abciximab or no abciximab in a prospective, randomized, open 2 × 2 factorial trial with blinded evaluation. Primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), defined as the composite of death, myocardial infarction (MI), stroke, repeat revascularization, and bleeding at 1 year (stent arm) and the composite of death, target vessel MI, target vessel revascularization (TVR), and bleeding at 30 days (abciximab arm). RESULTS: At 1 year, the rate of MACCE was lower in the SES arm (16.5% vs. 25.8%, p = 0.001), mainly driven by less repeat revascularization (9.8% vs. 16.8%; p = 0.003) and without influencing the cumulative incidence of death and MI (5.2% vs. 5.8%; p = 0.68). At 30 days, the rate of the composite of death, target vessel MI, TVR, and bleeding was lower in the abciximab arm (8.2% vs. 12.4%, p = 0.04), mainly driven by less TVR due to less stent thrombosis (1.2% vs.7.4%, p < 0.001). However, bleeding complications occurred more frequently in the abciximab group (5.7% vs. 2.8%, p = 0.03). CONCLUSIONS: Primary PCI with SES reduces adverse events at 1 year, mainly by reduction of repeat revascularization, whereas abciximab reduces early stent thrombosis, at the expense of more bleeding complications.
