What are the factors associated with atrial fibrillation recurrence?
Several factors have been associated with atrial fibrillation (AF) recurrence, including hyperthyroidism, postoperative status, and end-stage kidney disease. A 2016 study by Gördoğan et al. found that hyperthyroidism, age, and CHA2DS2-VASc score were predictors of AF recurrence in both hyperthyroid and euthyroid patients. A 2018 study by Lowres et al. identified postoperative status, presence of left atrial appendage thrombus, and higher EuroSCORE as independent predictors of AF recurrence in patients discharged in sinus rhythm after cardiac surgery. Additionally, a 2018 study by Park-Hansen et al. found that new-onset of postoperative AF is likely to recur in the absence of other triggers.
