Clinical characteristics
After excluding 793 patients, we ultimately studied 2737 from the AF
Frontier Ablation Registry who underwent first catheter ablation of AF
and completed the follow-up more than 3 months after the procedure (Fig.
1). Table 1 shows the study population’s clinical characteristics. The
population’s mean age was 63.4 ± 10.3 years, and 25.6% were female.
Patients with paroxysmal AF accounted for 62.7% of the population, and
the mean CHA2DS2-VASc score was 2.1 ±
1.5. The mean left ventricular ejection fraction (LVEF) was 63.6% ±
9.4%, and the mean left atrial diameter (LAD) was 40.1 ± 6.5 mm.
Warfarin was prescribed less frequently than direct oral anticoagulants
(DOACs) (20.4% vs. 79.6%); 43% of the patients continued to take OACs
throughout the follow-up period, and AADs were prescribed for 27.9% of
the patients at the end of the follow-up.
