Abstract：Objective To explore the relation between epicardial fat thickness (EFT) and recurrence of atrial fibrillation(AF) after radiofrequency ablation.Methods From January 2016 to April 2018,220 patients over 18 years old diagnosed as persistent AF undergoing radiofrequency ablation were enrolled at Nanjing Pukou Hospital of Traditional Chinese Medicine.EFT was measured by transthoracic echocardiography.All patients were followed up for 6 months after ablation to observe the recurrence of AF.Results During 6-month follow-up,66 patients(30.0％) had AF recurrence and 154 patients represented sinus rhythm without thromboembolism or hemorrhagic complications.Patients with AF recurrence had higher EFT and left ventricular end-diastolic diameter (LVEDD) as compared with patients with sinus rhythm [(8.3 ± 1.1) mm vs (6.2 ± 1.0) rm,(48 ± 3) mm vs (44 ±4) mm] (all P ＜ 0.01).Multiple logistic regression analysis showed that LVEDD (odds ratio =1.332,95 ％ confidence interval:1.011-1.702,P =0.032) and EFT (odds ratio =3.011,95 ％ confidence interval:1.023-8.142,P ＜ 0.001) were independent risk factors of AF recurrence after radiofrequency ablation.Conclusion EFT can be used as a valuable predictor of AF recurrence after radiofrequency ablation.
