Postoperative Atrial Fibrillation After Cardiac Surgery: Prevention and Management
\n(Society of Thoracic Surgeons -STS 2026)<\/p>\n
Key Points:<\/p>\n
\u2022\u2060 \u2060Postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery
\n\u2022\u2060 \u2060Typically occurs within the first 3\u20134 days postoperatively<\/p>\n
\u2022\u2060 \u2060Incidence:
\n\u2013 Up to 50% in combined CABG + valve surgery
\n\u2013 20\u201330% after isolated CABG
\n\u2013 30\u201340% after isolated valve procedures<\/p>\n
\u2022\u2060 \u2060Key Prevention Strategies:
\n\u2013 Beta-blockers = standard of care
\n\u2013 Amiodarone for high-risk patients
\n\u2013 Consider magnesium, corticosteroids, or colchicine in selected cases<\/p>\n
\u2022\u2060 \u2060Practical Amiodarone Prophylaxis:
\n\u2013 200 mg twice daily perioperatively
\n\u2013 Then 200 mg once daily<\/p>\n
\u2022\u2060 \u2060Management:
\n\u2013 Unstable patients \u2192 electrical cardioversion
\n\u2013 Stable patients \u2192 rate or rhythm control
\n\u2013 Anticoagulation based on individual stroke and bleeding risk<\/p>\n
\u2022\u2060 \u2060Anticoagulation:
\n\u2013 Usually short-term (4\u20136 weeks), as POAF is often transient
\n\u2013 Long-term only if AF persists or stroke risk is high<\/p>\n
\u2022\u2060 \u2060Bottom Line:
\n\u2013 POAF is common but preventable
\n\u2013 Early prophylaxis improves outcomes<\/p>\n
