What are the effects of statins on atrial fibrillation?
According to a collaborative meta-analysis of published and unpublished evidence from randomized controlled trials, statins have been found to reduce the risk of atrial fibrillation (AF) and other cardiovascular events. The meta-analysis found that statins were associated with a statistically significant reduction in the risk of AF compared to placebo (relative risk 0.81, 95% CI 0.70–0.94; p=0.006). Additionally, statins were also found to reduce the risk of other cardiovascular events such as stroke, myocardial infarction and death from any cause. Further studies are needed to confirm these findings and to determine the optimal dose and duration of statin treatment for AF prevention.
