New-onset postoperative atrial fibrillation management and outcomes: the VISION Cardiac Surgery cohort
Main finding · Stroke or vascular deathResult — go to the resultAdjusted hazard ratio 1.32 95% CI 0.99–1.77Authors' conclusion
New-onset POAF occurs in a third of patients after cardiac surgery; its antithrombotic and antiarrhythmic management varies. Patients with POAF have increased risks of both clinical AF and of all-cause death in the year following surgery.
