Effect of wenxin granule on early recurrence after radiofrequency ablation in patients with atrial fibrillation

AIM To discuss the effect of wenxin granule on early recurrence after radiofrequency ablation (RFCA) in patients with atrial fibrillation (AF). METHODSPersistent AF patients were randomized into wenxin granule group (n=35) and control group (n=36). The rate of AF early recurrence, NT-proBNP and left atrial diameter were observed before and 3 months after RFCA. RESULTSThe rate of AF early recurrence in wenxin granule group was significantly lower than in control group (8.6% vs. 30.6%; P<0.05). NT-proBNP and left atrial diameter in wenxin granule group were significantly lower than those in the control group 3 months after RFCA (P<0.05). CONCLUSIONWenxin granule can significantly lower the rate of AF early recurrence after RFCA and reduce NT-proBNP and left atrial diameter in patients with AF.
