Predictors of arrhythmia recurrence
In a multivariable model adjusting for the age, body mass index (BMI), CHA2DS2VASc score, AF type and duration, obstructive sleep apnea (OSA), chronic obstructive pulmonary disease (COPD), left ventricular ejection fraction (LVEF), and index RF vs. CB ablation, only LA size was independently associated with ATA recurrence at 1year. Each increment of 1 cm in LA size was associated with a 1.6-fold greater risk of ATA recurrence [HR=1.64, CI: 1.15-2.34, p<0.01] (Table 3).
