Objective: The association between the use of colchicine and the incidence of acute myocardial infarction (AMI) is inconsistent. The main objective of this study was to evaluate the effect of colchicine on the incidence of AMI. Assessment of the incidence of stroke and cardiovascular mortality were secondary endpoints. Methods: A meta-analysis of randomized studies that evaluated the use of colchicine in patients with atherosclerotic disease and reported cardiovascular events was performed, after searching the PubMed/MEDLINE, Embase, Scielo and Cochrane Controlled Trials databases. A fixed or random effects model were used depending on the heterogeneity observed. Results: Seven studies were selected for the analysis of the primary end point (5966 subjects in the colchicine arm and 5948 patients in the control arm). This meta-analysis demonstrated that colchicine therapy was associated with a lower risk of AMI (OR: 0.76, 95% CI: 0.62-0.92; I2 = 15%). Likewise, a significant reduction in the incidence of stroke was observed without a significant effect on cardiovascular mortality with pharmacological intervention. Conclusion: The use of colchicine in patients with atherosclerotic cardiovascular disease was associated with a significant reduction in the incidence of AMI. The incorporation of colchicine into the therapeutic arsenal of cardiovascular disease should be considered by future clinical practice guidelines.
