BACKGROUND Randomized controlled trials (RCTs) on the use of ranolazine (RN) for prevention and cardioversion of atrial fibrillation (AF) have yielded conflicting results.OBJECTIVE The purpose of this study was to conduct a meta-analysis of RCTs to examine the potential role of RN in the prevention and cardioversion of AF.METHODS PubMed and EMBASE were searched until June 2016. Of 484 initially identified studies, 8 RCTs were finally analyzed.RESULTS The analysis of RCTs showed that RN significantly reduced the incidence of AF compared to the control group in various clinical settings, such as after cardiac surgery, in acute coronary syndromes, and postelectrical cardioversion of AF (relative risk [RR] 0.67, 95% confidence interval [CI] 0.520.87, Z = 3.06, P = .002). Furthermore, a higher conversion rate of AF from the combined use of RN and amiodarone compared to amiodarone alone (RR 1.23, 95% CI 1.081.40, Z = 3.07, P = .002) was clear, with conversion time significantly shorter in RN plus amiodarone compared to the amiodarone group (weighted mean difference [WMD] = 10.38 hours, 95% CI 18.18 to 2.57, Z = 2.61, P = .009).CONCLUSION Our meta-analysis suggests that RN may be effective in AF prevention, whereas it potentiates and accelerates the conversion effect of amiodarone of recent-onset AF. Larger RCTs with long-term follow-up in diverse clinical settings are needed to further clarify the impact of RN on AF therapy.
