Drug-Eluting Balloon or Drug-Eluting Stent in Acute Myocardial Infarction: A Randomized Controlled Trial

In the experimental arm, a drug-coated balloon (DCB) with a concentration of 3 μg of Paclitaxel per 1 mm² will be used in patients with STEMI following successful lesion preparation (defined as residual stenosis ≤30%, TIMI flow grade 2-3, and absence of flow-limiting dissection). If the result after DCB treatment is unsatisfactory, a bailout drug-eluting stent (DES) will be implanted.

If the patient is randomized to the DES treatment arm, a second-generation drug-eluting stent (DES) will be implanted using standard techniques.
