Colchicine's Efficacy in MI Patients: Comparing PCI and Non-Reperfusion Approaches

This clinical trial, a prospective, focuses on patients with ST-Elevation Myocardial Infarction (STEMI) requiring Percutaneous Coronary Intervention (PCI) within 12 hours of onset. The study aims to control bias effectively through randomization, evenly distributing confounding factors across two groups. Patients, unknown to both researchers and themselves whether receiving Colchicine or a placebo, will undergo reperfusion therapy and optimal medicinal treatment according to the latest guidelines. The study population includes all STEMI patients in three cities in East Java (Jember, Malang, Tulungagung), selected through purposive sampling. The independent variable is Colchicine administration, while dependent variables include ventricular remodeling assessed by Left Ventricular End-Diastolic Volume (LVEDV) via echocardiography, serum levels of caspase-1, TGF-β, NT pro BNP and Galectin-3. All patients receive standard medical treatment pre-PCI, including aspirin and antiplatelet drugs, with post-PCI Optical Medical Treatment (OMT) following the latest guidelines.

The trial is randomized, double-blinded, and placebo-controlled, with participants divided into four groups: early PCI with Colchicine or placebo, and STEMI without reperfusion, receiving either Colchicine or placebo. This setup allows for a comprehensive comparison across different patient management strategies, exploring Colchicine's potential benefits in post-AMI care and its effects on key inflammatory and fibrotic markers.
