Patient Characteristics
A total of 1346 patients underwent first catheter ablation for AF during
this period, including 896 (66.5%) male patients and 450 (33.4%)
female patients. Table 1 shows comparison of baseline characteristics of
men and women. The female patient group was older at the time of
ablation (66.2y vs 62.4y; p<0.001] compared to male
patients. Women had higher CHA2DS2-VASc
scores (3 vs 2; p<0.001) than men at the time of ablation,
expectedly, given that female gender in the current guidelines confers a
CHA2DS2-VASc point. There was no
statistically significant difference in two groups in terms of BMI, DM,
HTN, hyperlipidemia, CHF, stroke history, or CKD. In our study
population, women had smaller LA diameter as compared to men (4.3 vs
4.5cm; p=0.024), and slightly reduced left-ventricular ejection fraction
(LVEF) values (55.9% vs 58.4%; p<0.001).
