Colchicine for cardiovascular secondary prevention: evidence from recent trials and meta-analyses

Abstract

PURPOSE OF REVIEW: Residual inflammatory risk remains an important driver of recurrent vascular events despite contemporary lipid-lowering and antithrombotic therapies. Low-dose colchicine is the first widely available anti-inflammatory therapy to be incorporated into contemporary guidelines for secondary prevention in coronary artery disease. This review summarizes contemporary evidence on the efficacy and safety of low-dose colchicine for secondary prevention. RECENT FINDINGS: Large randomized trials have demonstrated that colchicine reduces recurrent ischemic events in patients with chronic coronary disease and after myocardial infarction. Recent trials in acute myocardial infarction and stroke populations, however, have produced heterogeneous results. Nevertheless, contemporary meta-analyses consistently demonstrate reductions in major adverse cardiovascular events (MACE), driven mainly by fewer myocardial infarctions, strokes, and coronary revascularizations. Safety data are reassuring, with no consistent excess in serious infection, cancer, pneumonia, or noncardiovascular death, although gastrointestinal intolerance remains the most common adverse effect. SUMMARY: Low-dose colchicine has established residual inflammation as an actionable target in secondary prevention of vascular events in patients with chronic coronary disease or recent myocardial infarction. Ongoing trials will clarify colchicine's role across broader vascular indications. Future work should also focus on implementing the use of colchicine for prevention of clinical events in patients with coronary artery disease in clinical practice.
