Exclusion Criteria:
- Participation in other clinical trials.
- Cardiogenic shock or post-cardiac-arrest resuscitation state.
- Multi-vessel coronary artery disease.
- Severe calcified lesions requiring rotational atherectomy or shock-wave therapy.
- Only compliant or non-compliant plain balloon dilation performed.
- Both DES and DCB applied to the same culprit vessel.
- Culprit lesion located in a coronary bypass graft, or in-stent restenosis / in-stent thrombosis.
- Missing key angiographic or clinical follow-up data.

|---|---|
|
Drug-Coated Balloon (DCB) Cohort
STEMI patients with high thrombus burden who received drug-coated balloon (DCB) as the final revascularization strategy for culprit coronary vessel
|
A drug-coated balloon catheter used for percutaneous coronary intervention in patients with STEMI and high thrombus burden.
The balloon surface is coated with an antiproliferative drug (e.g., paclitaxel) that is transferred to the vessel wall during balloon inflation, inhibiting neointimal hyperplasia.
No permanent metal scaffold is implanted after DCB-only revascularization.
|
|
Drug-Eluting Stent (DES) Cohort
STEMI patients with high thrombus burden who received drug-eluting stent (DES) implantation as the final revascularization strategy for culprit coronary vessel, including bailout DES implantation after DCB.
|
A permanent coronary metal scaffold coated with an antiproliferative drug (e.g., sirolimus, everolimus, zotarolimus, or biolimus) implanted during percutaneous coronary intervention.
The stent maintains vessel patency and the eluted drug inhibits neointimal hyperplasia.
Used for culprit-vessel revascularization in STEMI patients with high thrombus burden, including bailout DES implantation after DCB predilation.

Incidence of immediate slow-flow or no-reflow after PCI
Zeitfenster: Immediately after the index emergency PCI procedure
|
The incidence of immediate slow-flow or no-reflow phenomenon after percutaneous coronary intervention (PCI) with either drug-coated balloon (DCB) or drug-eluting stent (DES).
Slow-flow/no-reflow is defined as TIMI flow grade ≤2 after the procedure in the absence of mechanical obstruction, dissection, or severe spasm.
