Abstract
En 中文
Background. Colchicine is an anti-inflammatory drug with promising efficacy for preventing cardiovascular events. We aimed to assess the pooled effect of colchicine on ischemic stroke among patients with established atherosclerotic cardiovascular diseases. Methods. PubMed, Scopus, Web of Science, and the Cochrane Library were systematically searched from the inception to August 5, 2024. A random-effects (DerSimonian-Laird) model was used to conduct this meta-analysis. The inclusion criteria were as follows: (I) being a randomized controlled trial; and (II) measuring the efficacy of colchicine compared to placebo for preventing ischemic stroke among those with established atherosclerotic cardiovascular diseases. Results. We identified 13 eligible clinical trials with 24900 participants. Colchicine significantly decreased the risk of ischemic stroke (relative risk (RR) 0.85, 95% confidence interval (CI) (0.72, 0.99), I2=2.92%) among those with established atherosclerotic cardiovascular diseases. Colchicine was more effective when used at 0.5 mg/day (RR 0.86, 95% CI (0.75, 0.99)), prescribed for more than 30 days (RR 0.86, 95% CI (0.75, 1.00)) or for more than 90 days (RR 0.65, 95% CI (0.46, 0.92)), or administered for patients with acute coronary syndrome (RR 0.46, 95% CI (0.23, 0.92)). In addition, colchicine was more effective in studies with a sample size of more than 500 patients, consistent with sensitivity analysis, which indicated that the results relied on large-sized clinical trials. Conclusion. Colchicine may decrease the risk of ischemic stroke among patients with established atherosclerotic cardiovascular diseases, particularly after long-term use; however, future studies are needed due to inconsistencies between existing trials.
