Colchicine and Atherosclerotic Coronary Artery Disease: An Updated Review.

Atherosclerotic coronary artery disease remains a leading cause of morbidity and mortality worldwide, despite advances in lipid-lowering and antithrombotic therapies. Increasing evidence highlights the pivotal role of inflammation in all stages of atherosclerosis, from plaque formation to rupture. Colchicine, a well-known anti-inflammatory drug traditionally used in gout and pericarditis, has emerged as a promising agent in the secondary prevention of cardiovascular events. Recent clinical trials have demonstrated significant reductions in cardiovascular outcomes with low-dose colchicine, especially in patients with stable CAD and following myocardial infarction. This review provides an updated overview of the pathophysiological rationale for colchicine use in atherosclerosis, summarizes key clinical trial data, and discusses potential mechanisms, safety considerations, and future directions.
