Predictors of the recurrence of AF
Univariate and multivariate analyses were performed to identify the predictors of the recurrence of AF after CA. The results of the Cox regression analysis are presented in Table 2. In the multivariate analysis, LA reverse remodeling (hazard ratio, 0.19; 95% confidence interval, 0.08–0.46; p<0.01) and early recurrence during the blanking period (hazard ratio, 3.03; 95% confidence interval 1.12–8.12; p=0.027) were independently associated with the recurrence of AF after CA.
The Kaplan-Meier analysis showed that patients who achieved LA reverse remodeling had significantly fewer recurrences of AF after CA than those who did not (Figure 3).
