Late recurrence of atrial fibrillation
Among the 2737 patients included in this analysis, 2070 (75.6%) were
free from AF, whereas 667 (24.4%) experienced a late recurrence of AF.
The follow-up for the AF nonrecurrence group and AF recurrence group was
4175 and 1573 person-years, respectively. Table 1 lists the patient
characteristics of the AF nonrecurrence and AF recurrence groups.
Compared with the AF recurrence group, the AF nonrecurrence group
exhibited a significantly lower rate of persistent AF (34.7% vs.
45.3%, P < 0.001), dyslipidemia (34.9% vs. 39.3%,P = 0.039), nonischemic myocardiopathy (3.1% vs. 5.3%, P= 0.01), warfarin use (17.5% vs. 29.4%, P < 0.001),
continuation of OAC use (35.3% vs. 67.2%, P < 0.001),
AAD use (21.3% vs. 27.9, < 0.001), and smaller baseline LAD
(39.7 ± 6.4 mm vs. 41.5 ± 6.4 mm, P < 0.001).
