Indicators of atrial fibrillation risk in cardiac surgery patients on prophylactic amiodarone.
Atrial fibrillation is a common complication of cardiothoracic surgery (coronary artery bypass graft surgery or cardiac valve repair or replacement). Although predictors of postoperative atrial fibrillation have been explored in patients not receiving prophylactic antiarrhythmic therapy, independent predictors of postoperative atrial fibrillation in patients receiving prophylactic amiodarone have not been elucidated. ⋯ This subanalysis demonstrates some novel predictors of postoperative atrial fibrillation, including diabetes mellitus and postoperative nonsteroidal antiinflammatory drug use. We have also demonstrated that predictors of atrial fibrillation differ when prophylactic amiodarone is used.
