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

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.
