Colchicine in Belgium in Patients With Coronary Artery Disease After Percutaneous Coronary Intervention

Summary

The main aim of this trial is to determine whether there are fewer cardiovascular events when patients with coronary artery disease take a low dose of colchicine of 0.5 mg daily on top of optimal standard treatment after treatment with PCI, compared with placebo in combination with optimal standard treatment. More specifically, we aim to investigate the benefits of a daily low dose of colchicine in patients with coronary artery disease after treatment with PCI, to confirm that a daily low dose of colchicine helps prevent additional incidents in coronary artery disease, and to identify a subgroup of patients with CAD who are at increased risk for cardiovascular events and could benefit most from colchicine.
