The aim of the study is to demonstrate the safety and efficacy of the TCD-10023 (Ultimaster) sirolimus eluting stent in patients with acute ST-elevation myocardial infarction (STEMI), by proving superiority with respect to in-stent late loss at 6 months to the Kaname bare metal stent and non-inferiority with respect to Target Vessel Failure (TVF) at 12 months.
