Reevaluating New-Onset Atrial Fibrillation After CABG: Insights from Long-Term Continuous Monitoring

Highlight

• New-onset atrial fibrillation (AF) incidence within one year post-CABG is nearly 48%, significantly higher than previous reports.
• The burden of AF episodes detected is remarkably low, especially beyond 30 days after surgery.
• Findings suggest current guidelines recommending 60 days of oral anticoagulation after new-onset AF post-CABG may warrant reconsideration.
• Long-term continuous ECG monitoring with insertable cardiac monitors provides critical insights into AF dynamics following cardiac surgery.
