One‐year outcome from an all‐comers population of patients with ST ‐segment elevation myocardial infarction treated with biolimus‐eluting stent with biodegradable polymer

OBJECTIVES: To evaluate the performance of biolimus-eluting stent (BES) in patients with ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) in a real world clinical scenario. BACKGROUND: Randomized studies suggest that the BES with biodegradable polymer is more effective and safe than early generation coronary stents in patients with STEMI. METHODS: We included all consecutive STEMI patients undergoing PCI in this prospective, multicenter registry. The primary endpoint of the study was the rate of major adverse cardiac events (MACE), a composite of cardiac death, recurrent myocardial infarction and ischemia-driven target vessel revascularization at 1-year follow-up. RESULTS: Between June and December 2012 we enrolled 311 STEMI patients. The primary endpoint occurred in 3.2% (95% confidence interval: 1.6-5.8) of patients: cardiac death, re-infarction, and ischemia-driven TVR occurred in 2.3%, 1.3%, and 0.6% of patients, respectively. One-year MACE-free survival was 96.8% ± 1.0%. CONCLUSIONS: In a real-world cohort of STEMI patients undergoing PCI, the use of BES is associated with good 1-year clinical outcome. These results confirm and expand previous findings showing the efficacy and safety of BES in the setting of randomized trials.
