Postoperative atrial fibrillation: Prediction of subsequent recurrences with clinical risk modeling and artificial intelligence electrocardiography

Postoperative atrial fibrillation (POAF) after noncardiac surgery comprises around 13% of all new AF diagnoses in the community and has been associated with increased risk of subsequent stroke and transient ischemic attack compared to those without a history of AF.1-3 However, the management of POAF after non-cardiac surgery, including the indications and approaches to ambulatory rhythm monitoring and oral anticoagulation (OAC) for stroke prophylaxis, remains uncertain. Recent data have also demonstrated that AF tends to recur in about one third of patients with POAF within the first year of the index POAF episode4.
