Abstract:Objective To compare the long-term curative effects of radiofrequency ablation (RFA) and antiarrhythmic drugs (AAD) in treatment of persistent atrial fibrillation (AF).Methods The patients with persistent AF (n=60), with disease course from 3 months to 9 months and left atrial anteroposterior diameter<45 mm and LVEF>50%, were chosen from Department of Cardiology in People's Hospital of Inner Mongolian Autonomous Region from Jan.2010 to Mar.2016.The patients were divided, according to therapeutic methods, into RFA group (n=30) received RFA treatment including circumferential pulmonary vein isolation and linear ablation, and control group (n=30) treated with AAD.All patients were followed up for an average 3 y after treatment.Whether the patients could maintain sinus rhythm for long time was analyzed in 2 groups after discharged from hospital.Results There were 23 male cases and 7 female cases aged from 47 to 72 with an average age= (59.8±7.1) years old in RFA group.There were 20 male cases and 10 female cases aged from 48 to 73 with an average age= (62.8±6.5) years old in control group.The difference in sex, age, left atrial diameter (LAD) and LVEF had no statistical significance between 2 groups (all P>0.05).The long-term effective rate was 46.7%in RFA group and 16.7%in control group (P=0.012).Conclusion The long-term effective rate is higher in patients with persistent AF treated with RFA than that in those treated with AAD.
