Beschrijving
Inclusion Criteria:
- Age ≥ 18 years.
- First electrocardiogram on arrival shows ST-segment elevation ≥ 2 mm in at least two contiguous anterior leads, or sum of ST-segment elevation ≥ 4 mm in anterior leads.
- Ischemic symptoms (chest pain, chest tightness, upper abdominal discomfort, left shoulder radiation, etc.) onset to hospital arrival between ≥ 4 hours and ≤ 12 hours, and planned for primary PCI.
- Coronary angiography confirms the infarct-related artery is the proximal left anterior descending (LAD) (before the first septal branch or first diagonal branch) with TIMI flow grade 0 (total occlusion).
- Patient or legal representative provides written informed consent.
Exclusion Criteria:
- Established cardiogenic shock (systolic blood pressure < 90 mmHg without inotropes/vasopressors, or requiring vasopressors to maintain systolic blood pressure ≥ 90 mmHg, AND blood lactate > 2.0 mmol/L).
- Severe heart failure: Killip class ≥ III, or requiring non-invasive/invasive positive pressure ventilation before enrollment.
- Malignant arrhythmias, including cardiac arrest, ventricular fibrillation, ventricular flutter, pulseless ventricular tachycardia, or high-grade atrioventricular block.
- Severe mechanical complications (e.g., free wall rupture, ventricular septal defect, acute severe mitral regurgitation).
- Contraindications to IABP (severe peripheral vascular disease, aortic dissection, known aortic aneurysm, moderate-to-severe aortic regurgitation).
- Prior myocardial infarction or known chronic heart failure (left ventricular ejection fraction < 50%).
- Prior coronary artery bypass grafting (CABG).
- Stroke within 1 month, or history of hemorrhagic stroke at any time.
- Active gastrointestinal bleeding within 3 months, or gastrointestinal diseases with increased bleeding risk.
- Received thrombolytic therapy for this episode.
- Initiation of any mechanical circulatory support (IABP, Impella, ECMO) before coronary angiography.
- Severe hepatic insufficiency (Child-Pugh C, or ALT >5×ULN with total bilirubin >3×ULN), renal insufficiency (eGFR < 15 mL/min/1.73 m² or chronic dialysis), or end-stage disease with life expectancy < 1 year.
- Pregnancy or lactation.
- Currently participating in another interventional trial.

Experimenteel: Prophylactic IABP + PPCI
Participants randomized to this arm will receive prophylactic intra-aortic balloon pump counterpulsation before primary percutaneous coronary intervention (PPCI), followed by standard PPCI and guideline-directed medical therapy.
|
Intra-aortic balloon counterpulsation initiated before opening the infarct-related artery and maintained according to protocol.
Standard primary percutaneous coronary intervention for infarct-related artery reperfusion.
|
|
Actieve vergelijker: Standard PPCI Alone
Participants randomized to this arm will receive standard PPCI and guideline-directed medical therapy without routine prophylactic IABP.
Rescue IABP may be used only if clinically indicated according to protocol.
|
Standard primary percutaneous coronary intervention for infarct-related artery reperfusion.
