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).
