Clinical Characteristics of Patients with Early or Late Recurrence
In the Non-CF group, there was no significant difference in the baseline patient characteristics, RF delivery time, and delivered RF energy between the patients with and without ER (data not shown). On the other hand in the CF group, the patients with ER included a higher proportion of females, had a longer disease duration of PAF, higher pre-operative plasma brain-type natriuretic peptide (BNP) level, longer RF delivery time, and larger amount of RF delivery than those without ER (Female, 42.9% vs. 24.9%, p=0.001; disease duration of PAF, 41.2 ± 41.4 vs. 25.5 ± 24.4 months, p<0.001; BNP, 66.9 ± 58.7 vs. 43.5 ± 33.1 pg/ml, p<0.001; RF delivery time, 2185.4 ± 585.2 vs. 1963.4 ± 476.1 sec., p=0.017; amount of RF energy, 56349.7 ± 14616.6 vs. 52239.3 ± 12397.5 J, p=0.070).
In the Non-CF group, the baseline patient characteristics was not different between those with and those without LR (data not shown). In the CF group, the disease duration of PAF was longer in patients with LR than in those without LR (37.4 ± 34.6 vs. 30.3 ± 34.6 months, p = 0.005), and the prevalence of hypertension, the CHA2DS2-VASc score, and pre-procedural BNP level were higher in those with than in those without LR(Hypertension, 66.2% vs. 49.8%, p=0.013; CHA2DS2-VASc score, 2.2 ± 1.2 vs. 1.8 ± 1.2, p=0.042; BNP, 62.2 ± 51.2 vs. 50.3 ± 45.2 pg/ml, p=0.026).
