Results
This study included a total of 2293 patients undergoing catheter
ablation for the first time, with 1441 males and 852 females (Figure 1).
Within this group, 145 patients underwent additional catheter ablation
procedures during the follow-up period. In the present cohort, the
average age of the patients was 59.88 ± 10.61 years; 37.9% had
persistent AF; the duration from diagnosis to ablation was 36.17 ± 39.08
months; the CHA2DS2-VASc and HAS-BLED
scores were 1.88 ± 1.56 and 0.51 ± 0.66, respectively; and 46.7% of
patients underwent non-PV ablation. Females were significantly higher
than males in terms of age, duration from diagnosis to ablation,
CHA2DS2-VASc scores, HAS-BLED scores,
and the prevalence of hypertension and vascular diseases; however, they
had a significantly lower proportion of persistent AF and underwent
non-PV ablation procedures less frequently (Table 1). After 1:1 PSM, the
variables were comparable among groups (Supplementary Table S1).
