Outcomes of postoperative atrial fibrillation (AF) after noncardiac surgery are not well defined. ⋯ Among patients undergoing noncardiac surgery, new-onset postoperative AF compared with no AF was associated with a significant increased risk of stroke or TIA. However, the implications of these findings for the management of postoperative AF, such as the need for anticoagulation therapy, require investigation in randomized trials.
