Background: The aim was to ascertain the 1-year clinical outcomes of 1,234 patients who underwent implantations of sirolimus-eluting stents (SES) for acute myocardial infarction (MI) in the multinational e-SELECT registry. Methods: Fifteen thousand and one hundred and forty-seven patients treated with SES were entered in the e-SELECT registry, of whom 1,234 presented within <24 hours of onset of acute MI. Results: At 1 year, the rates of major adverse cardiac events (MACE) (5.5% vs. 4.8%; P = 0.28) were similarly low in the acute and no acute MI groups. The rates of definite/probable stent thrombosis (ST) were higher in the acute MI group (2.1%vs; 0.88%, P < 0.001). ST was a strong independent predictor of death at 1 year (HR 13.4; 95% CI 5.0, 36.0; P < 0.001) and MI (HR 58.9; 95% CI 26.9, 129.1; P < 0.001). Dual antiplatelet therapy (DAPT) compliance at 6 months was 96.0% in the acute MI versus 94.5% in the no acute MI group (P = 0.03). Conclusion: In selected patients presenting within <24 hours of acute MI onset and highly compliant with DAPT, SES implantation was associated with similar rates of MACE, though higher rates of ST, as compared to no acute MI patients. Condensed abstract In the e-SELECT registry which included 15,147 patients treated with sirolimus-eluting stent (SES), we ascertained the 1-year clinical outcomes of 1,234 patients who presented within <24 hours of acute MI onset. In acute MI patients SES implantation was associated with similar rates of MACE, though higher rates of ST, as compared to no acute MI patients (MACE: 5.5% vs. 4.8%; P = 0.28; ST: 2.1 vs. 0.88%, P < 0.001).
