Why the study?
Is new-onset postoperative atrial fibrillation associated with an increased risk of stroke or TIA in patients undergoing noncardiac surgery?
Is new-onset postoperative atrial fibrillation associated with an increased risk of stroke or TIA in patients undergoing noncardiac surgery?
New-onset atrial fibrillation after noncardiac surgery is associated with an increased risk of subsequent stroke or TIA, highlighting the need for randomized trials to determine the role of anticoagulation in this population.
May heighten postoperative stroke vigilance after noncardiac surgery; leaves open anticoagulation benefit pending randomized trials.
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.
