Key result
Postoperative atrial fibrillation within seven days after cardiac surgery was associated with a significantly increased risk of thromboembolic stroke during hospital admission (adjusted OR 3.01; 95% CI 1.13-8.00).
Why the study?
The authors aimed to study the association between POAF and thromboembolic stroke and determine risk factors for thromboembolic stroke after cardiac surgery.
Is postoperative atrial fibrillation associated with an increased risk of thromboembolic stroke in adult cardiac surgery patients?

Is postoperative atrial fibrillation associated with an increased risk of thromboembolic stroke in adult cardiac surgery patients?
Odds Ratio: 3.01 (95% CI 1.13–8)
Postoperative atrial fibrillation within seven days of cardiac surgery is associated with a three-fold increased risk of early thromboembolic stroke during hospital admission.
POAF triples early stroke risk after cardiac surgery; extends prior associations and supports anticoagulation trials in this population.

Pierik et al. (2021) conducted an observational in Cardiac surgery (n=910). Postoperative atrial fibrillation (POAF) vs. No postoperative atrial fibrillation was evaluated on Thromboembolic stroke during hospital admission (adjusted OR 3.01, 95% CI 1.13-8.00). Postoperative atrial fibrillation within seven days after cardiac surgery was associated with a significantly increased risk of thromboembolic stroke during hospital admission (adjusted OR 3.01; 95% CI 1.13-8.00).
