Postoperative Atrial Fibrillation - What Do We Really Know?
Key result
Beta-blockers with adjunctive amiodarone reduce postoperative atrial fibrillation following cardiac surgery.
Why the study?
Postoperative atrial fibrillation is a common complication after cardiac surgery with multifactorial pathogenesis and unclear optimal prevention and treatment strategies.
Population
Patients undergoing cardiac surgery at risk for or developing POAF

Implication
May support beta-blocker plus amiodarone for POAF prevention; leaves open optimal regimens and anticoagulation need.
Key Points
- To review the incidence, risk factors, underlying pathophysiological mechanisms, and clinical management strategies for postoperative atrial fibrillation.
- Reviewed clinical evidence addressing the incidence, clinical predictors, and biological mechanisms of postoperative atrial fibrillation (POAF).
- Assessed pharmacological interventions, symptom-guided rate versus rhythm control approaches, and surgical ablation therapies used in cardiac surgery settings.
- POAF occurs in 20% to 60% of cardiac surgery patients, driven by advanced age, preexisting cardiac and pulmonary comorbidities, and systemic inflammation triggered by cardiopulmonary bypass.
- Prophylactic regimens utilizing beta-blockers combined with adjunctive amiodarone show substantial reductions in POAF incidence and associated adverse outcomes.
- Because POAF is predominantly a transient condition, individualized symptom control is prioritized, and the bleeding hazards of full anticoagulation may outweigh its preventive benefits.

I
Intervention
Pharmacological prevention (beta-blockers, amiodarone), rate vs rhythm control, and surgical ablation
Beta-blockers with adjunctive amiodarone are effective for preventing POAF, while the transient nature of the condition suggests anticoagulation risks may outweigh benefits.
