Abstract：Objective To investigate the influencing factors of recurrence of chronic atrial fibrillation (CAF) after radiofrequency ablation (RFA). Methods CAF patients (n=110) were chosen from the Department of Cardiology of the Seventh People’s Hospital of Zhengzhou City from June 2016 to Mar. 2018, and their recurrence situations were retrospectively analyzed after RFA. The influencing factors of CAF recurrence were analyzed by applying multi-factor Logistic regression analysis. Results During the follow-up period for 3 months, the recurrence was occurred in 49 cases. The comparison in general data between recurrence group and non-recurrence group showed that there were greatly significant statistical differences in left atrial anteroposterior diameter (LAAPD) and left atrial diameter index (LADI, P<0.05). The results of multi-factor Logistic regression analysis indicated that LAAPD (OR=1.194, 95%CI: 1.097~1.299, P<0.01), LADI (OR=2.669, 95%CI: 1.032~6.903, P=0.043) and persistent atrial fibrillation (OR=0.071, 95%CI: 0.021~0.246, P<0.01) were influencing factors of CAF recurrence in CAF patients after RFA. Conclusion The types of atrial fibrillation, LAAPD and LADI are influencing factors of CAF recurrence in CAF patients after RFA. In order to reduce CAF recurrence rate and improve RFA success rate, the ablation strategy should be optimized.
