Backgroundfew long-term randomized data on safety and effectiveness of sirolimus-eluting stent (SES) in the ST-segment elevation myocardial infarction (STEMI) setting are available. The aim of the present investigation was to evaluate the 5-year clinical outcome of SES vs bare-metal stent (BMS) implantation in patients with STEMI.Methods320 STEMI patients were randomized to receive SES or BMS. The primary end-point was the incidence of target vessel failure (TVF) at 5-year follow-up. The secondary end-points were the rate of target lesion revascularization (TLR), major adverse cardiovascular events (MACE), death or non-fatal MI and stent thrombosis (ST). Event rates from 1 to 5 years in patients undergoing TLR and those TLR free at 1 year were also investigated.ResultsThe 5-year survival rate free from TVF and TLR was significantly higher in the SES than in the BMS group (85% vs 76% p = 0.038; 92% vs 85% p = 0.045, respectively). The lower incidence of adverse events was achieved in the first year of follow-up. The cumulative incidence of MACE, death or non-fatal MI and ST was comparable in the 2 groups at 5-year follow-up. Moreover death or MI incidence was 5% in the patients who did not experience TLR within 1-year and 16% in those who experience TLR in the same period (p = 0.033). Predictors of death or MI during 5-year follow-up were TLR within 1 year (OR 3.4, 95% CI 1.1-10.1; p = 0.04) and small vessels treatment (OR 4.8 95% CI 1.7-13.0; p = 0.002).ConclusionsThe clinical benefits of SES are maintained up to 5 years without safety concerns.
