Association Between Serum Uric Acid Levels and Atrial Fibrillation Risk

Abstract

Background: Several studies were published to assess the association between serum uric acid levels and atrial fibrillation risk, but no consistent results were reported. We performed a meta-analysis to evaluate the evidence of the association between hyperuricemia and atrial fibrillation risk. Material/Methods: Pubmed and Embase databases were searched for prospective cohort studies assessing the association between hyperuricemia and atrial fibrillation risk. Relative risks (RRs) with corresponding 95% confidence intervals (95%CIs) were pooled using random-effect of meta-analysis to assess the risk of atrial fibrillation in individuals with hyperuricemia. Results: Six cohort studies were finally included into the meta-analysis. Meta-analysis of those 6 studies showed that hyperuricemia was significantly associated with increased risk of atrial fibrillation (RR = 1.49, 95%CI 1.24-1.79, P Conclusions: Based on the currently available data, hyperuricemia is associated with increased risk of atrial fibrillation
