Background-This study sought to determine whether the 1-year differences in major adverse cardiac event between a stent eluting biolimus from a biodegradable polymer and bare-metal stents (BMSs) in the COMFORTABLE trial (Comparison of Biolimus Eluted From an Erodible Stent Coating With Bare Metal Stents in Acute ST-Elevation Myocardial Infarction) were sustained during long-term follow-up. Methods and Results-A total of 1161 patients were randomly assigned to biolimus-eluting stent (BES) and BMS at 11 centers, and follow-up rates at 2 years were 96.3%. A subgroup of 103 patients underwent angiography at 13 months. At 2 years, differences in the primary end point of cardiac death, target-vessel myocardial infarction, and target lesion revascularization continued to diverge in favor of BES-treated patients (5.8%) compared with BMS-treated patients (11.9%; hazard ratio=0.48; 95% confdence interval, 0.31-0.72; P<0.001) with a signifcant risk reduction during the second year of follow-up (hazard ratio 1-2 years=0.45; 95% confdence interval, 0.20-1.00; P=0.049). Differences in the primary end point were driven by a reduction in target lesion revascularization (3.1% versus 8.2%; P<0.001) and target-vessel reinfarction (1.3% versus 3.4%; P=0.023). The composite of death, any reinfarction and revascularization (14.5% versus 19.3%; P=0.03), and cardiac death or target-vessel myocardial infarction (4.2% versus 7.2%; P=0.036) were less frequent among BES-treated patients compared with BMS-treated patients. The 13-month angiographic in-stent percent diameter stenosis amounted to 12.0±7.2 in BES- and 39.6±25.2 in BMS-treated lesions (P<0.001). Conclusions-Among patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention, BES continued to improve cardiovascular events compared with BMS beyond 1 year.
