Recurrence after atrial fibrillation (AF) ablation is still common. This study aimed to evaluate the predictive abilities of AF duration and early recurrence (ER) discriminate high-risk patients for recurrence. We enrolled 1,763 consecutive with who were scheduled receive index radiofrequency catheter (RFCA) from January 2016 August 2021 in Dalian, China. Long (LAFD) was considered if course lasted ≥ 12 months. ER defined as any tachycardia (AT) or event longer than 30 s occurring within a 3-month post-RFCA. Late occurred 643 (36.5%) at median 35 months RFCA. Multivariate analysis identified LAFD (hazard ratio (HR): 1.80, 95% confidence interval (CI): 1.38-2.35, p < 0.001) (HR: 2.34, CI: 1.82-3.01, strong independent predictors late non-paroxysmal AF. Similarly, 1.48, 1.20-1.84, 3.40, 2.68-4.30, significantly associated paroxysmal Receiver operating curve analyses revealed that CAAP-AF (CAD, Atrial diameter, Age, Persistent longstanding AF, Antiarrhythmic drugs failed, Female) had highest predict power [area under ROC (AUC) 0.586]. The addition score improved risk discrimination 0.586 0.686. independently prediction performance model by ER.
