Abstract | BACKGROUND: METHODS AND RESULTS: A total of 757 patients who underwent radiofrequency catheter ablation of AF were divided into heart failure (HF, n=79) and non-HF (n=678) groups; RDW was assessed as a predictor after catheter ablation in each. During a 22.3-month follow-up period, the baseline RDW in the HF group was greater in the recurrence group than in the non-recurrence group (14.5±2.0% vs. 13.5±0.9%, P=0.013). In contrast, no significant difference in RDW at baseline was found in the non-HF group between the recurrence and non-recurrence groups (13.3±0.8% vs. 13.2±0.8%, P=0.332, respectively). Multivariate analysis demonstrated that RDW (hazard ratio 1.20, 95% confidence interval 1.01-1.40, P=0.034) was an independent predictor of AF recurrence in the HF group. The cut-off values of RDW for the recurrence of AF and major adverse events in the HF group were 13.9% and 14.8%, respectively. CONCLUSIONS: High RDW is an independent predictor for the recurrence of AF and major adverse events in patients with HF after catheter ablation. RDW is a potential noninvasive marker in AF patients complicated with HF. (Circ J 2016; 80: 627-638).
