Summary

Trial Goals: 1. Evaluation of Mid- to Long-Term Safety and Effectiveness of Drug-Coated Autoperfusion Balloon Dilatation Catheter (DCAB) versus Conventional Drug coated balloon (DCB) in Patients with ST Segment Elevation Myocardial Infarction (STEMI). 2. Evaluation of Hybrid IVUS-OCT System for Intraoperative Evaluation of DCAB or Conventional DCB Treatment Safety and Effectiveness for De Novo Lesions During Emergency Percutaneous Coronary Intervention (PCI) in Patients with STEMI. The primary outcome is late lumen loss (LLL) assessed at 9 months following emergency PCI, measured using quantitative coronary angiography (QCA).

Conditions

• ST Segment Elevation Myocardial Infarction (STEMI)

Interventions

Type	Name	Description
DEVICE	Drug Coated Autoperfusion Balloon Dilatation Catheter（DCAB）	In the experimental arm, under the assessment and guidance of IVUS-OCT, STEMI patients with successfully prepared lesions will be treated with a drug-coated autoperfusion balloon dilatation catheter (DCAB). Successful lesion preparation is defined as post-pretreatment residual stenosis ≤ 30%, no type C dissections, intravascular imaging confirming no significant residual plaque burden at the dissection site, no transverse expansion \> 60°, no longitudinal expansion \> 2 mm, no dissection involving the media or adventitia, and no location at the stent distal end. There should be no hematoma and no significant thrombus (TIMI thrombus burden grade ≤ 2). If the angiographic and intravascular imaging results after DCAB treatment are unsatisfactory, an emergency drug-eluting stent (DES) will be implanted.
DEVICE	Conventional Drug coated balloon (DCB)	In the control arm, under the assessment and guidance of IVUS-OCT, STEMI patients with successful lesion preparation (residual stenosis ≤ 30%, no type C dissections, no significant residual plaque burden, no dissection involving the media or adventitia, no transverse expansion \> 60°, no longitudinal expansion \> 2 mm, no location at the stent distal end, no hematoma, TIMI thrombus burden grade ≤ 2) will be treated with a conventional DCB coated with 3 μg/mm2 paclitaxel. If angiographic and intravascular imaging results are unsatisfactory, a bailout DES will be implanted.
