Drug-coated balloon versus drug-eluting stent for young adults with STEMI

Drug Coated Balloon vs. Drug Eluting Stent in Young Patients With STEMI: The DCB-STEMI Randomized Trial

Phase 3 Interventional National Institute of Cardiovascular Diseases, Pakistan · NCT07229248

This study tests whether a paclitaxel-coated balloon works as well as a drug-eluting stent for adults under 50 who have a STEMI and undergo primary PCI.

What this trial studies

This is a single-center, randomized controlled Phase 3 trial at the National Institute of Cardiovascular Diseases (Karachi) comparing a paclitaxel-coated balloon (3.0 µg/mm² with 30-second inflation) to standard drug-eluting stents in young adults (<50 years) presenting with STEMI undergoing primary PCI. Participants are randomized to receive either the drug-coated balloon or a DES, with the primary endpoint of 1-year vessel-oriented cardiac events (VOCE). The trial enrolls stable patients with low SYNTAX scores and total ischemic time under 8 hours, while excluding those with severe multivessel disease, high SYNTAX scores, ESRD, or complex lesions. The design tests a 'leave nothing behind' strategy intended to avoid permanent implants, potentially shorten dual antiplatelet therapy, and reduce long-term device-related complications.

Who should consider this trial

Good fit: Adults aged 18–50 with first-presentation STEMI who are stable (Killip I–II), have low SYNTAX scores, total ischemic time under 8 hours, and are undergoing primary PCI are the intended candidates.

Not a fit: Patients with severe multivessel disease, intermediate or high SYNTAX scores, complex lesion anatomy, end-stage renal disease, or hemodynamic instability (Killip III–IV) are unlikely to be eligible or to benefit from the DCB strategy.

Why it matters

Potential benefit: If successful, this approach could reduce lifelong stent-related risks, shorten the duration of dual antiplatelet therapy, and lower rates of restenosis and stent thrombosis in younger STEMI patients.

How similar studies have performed: Observational studies, meta-analyses, and reports including a JACC: CVI analysis have suggested comparable outcomes between DCB and DES in STEMI, but randomized Phase 3 evidence specifically in young patients is limited.
