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).
