Summary

Acute myocardial infarction (AMI) remains a major cause of morbidity and mortality, particularly in patients with multivessel coronary artery disease. Although primary percutaneous coronary intervention (PCI) has significantly improved short-term outcomes, these patients remain at high risk of recurrent cardiovascular events due to vulnerable non-culprit plaques. Coronary imaging techniques such as intravascular ultrasound (IVUS), optical coherence tomography (OCT), and angiography-derived indices (QFR, RWS) can identify high-risk lesions, but the optimal management strategy is still debated.

Early and intensive lipid-lowering therapy has been shown to stabilize atherosclerotic plaques. PCSK9 monoclonal antibodies, in combination with statins, provide rapid and profound LDL-cholesterol reduction and may enhance plaque stabilization beyond standard therapy. Small imaging studies suggest favorable effects of PCSK9 inhibitors on fibrous cap thickness and lipid burden, but their impact on clinical outcomes in AMI patients with multivessel disease remains uncertain.

This study aims to evaluate whether very early in-hospital administration of a PCSK9 inhibitor, in addition to standard care, can reduce major adverse cardiovascular events (MACE) over 12 months compared with standard lipid-lowering therapy alone. The trial will also explore imaging-based markers of plaque vulnerability and functional indices as secondary endpoints, in order to better understand the mechanisms linking lipid lowering, plaque stabilization, and clinical outcomes.

Conditions

  • Acute Myocardial Infarction (AMI)

Interventions

DRUG

Standard Lipid-Lowering Therapy

Participants will receive lipid-lowering therapy according to current clinical guidelines. Treatment will be initiated with statins. Based on follow-up lipid levels, ezetimibe may be added, and PCSK9 inhibitor therapy may be considered if LDL-C goals are not met.

DRUG

Early Intensive Lipid-Lowering Therapy (PCSK9 Inhibitor)

Participants will receive early intensive lipid-lowering therapy with a PCSK9 monoclonal antibody, initiated during the index hospitalization, in addition to statins. Ezetimibe may be added if clinically indicated. The PCSK9 inhibitor will be administered regardless of baseline lipid levels.
