ER was defined as documented recurrence in the blanking period (days 1\u201390), and LR as recurrence in the evaluation period (days 91\u2013365). Freedom from 12-month recurrence was estimated using Kaplan\u2013Meier method. A Cox proportional-hazards regression model, with ER as the primary factor, and adjusted for age, sex, and body mass index, was used to estimate hazard ratios (HRs) and 95% CI. ER was observed in 20.1% (31\/169) of patients (66.1 \u00b1 7.1 years, 35.5% female, 46.6 \u00b1 48.4-month PAF history). Time to first documented ER was 49 (37\u201361) days. Occurrence of LR was 16.7% (23\/138) in patients without ER, 71.0% (22\/31) in those with ER, and 87.0% (20\/23) in patients whose ER onset occurred within the first 2 months. Twelve-month freedom from documented recurrence was significantly lower in patients with ER at 29.0% (95% CI, 13.1\u201345.0%) vs. 82.5% (95% CI, 75.9\u201389.1%) in those without ER (adjusted HR, 7.9; 95% CI, 4.1\u201315.1; P &amp;lt; 0.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>This admIRE subanalysis demonstrated that PAF patients who experience ER after PFA are at a substantially higher risk for LR.
