BACKGROUND: Management of atrial fibrillation (AF) at the time of coronary artery bypass grafting (CABG) is a class 1 recommendation. This study evaluated trends in AF management and their association with long-term survival.
METHODS: Patients with paroxysmal or persistent AF who underwent isolated CABG were identified from The Society of Thoracic Surgeons Adult Cardiac Surgery Database (2011-2022) with linkage to Medicare claims for long-term outcomes. Patients were stratified by AF treatment: none, left atrial appendage occlusion (LAAO) only, epicardial ablation (EA), or intracardiac ablation (IA). The primary end point was all-cause mortality; secondary end points included permanent pacemaker placement, stroke, and readmission for AF, bleeding, or heart failure. Long-term mortality was assessed using Kaplan-Meier methods and Cox regression. Nonfatal outcomes were assessed using competing-risk regression with death as the competing event.
RESULTS: Among 59,331 patients, 71.0% had paroxysmal AF, increasing from 56.6% (2011) to 79.6% (2022). AF treatment included none (51.0%), LAAO only (15.3%), EA (25.4%), and IA (8.2%). AF treatment increased from 31.8% to 68.8%, driven by LAAO (1.2%-30.8%). Patients with persistent AF had higher mortality than patients with paroxysmal AF (P < .001). EA showed lower mortality compared with no treatment. IA was associated with higher pacemaker implantation (6.0% vs 3.2%-3.4% in other groups; P < .001). Compared with no treatment, all treatment groups had lower stroke risk (subdistribution hazard ratio, 0.64-0.79; P < .001) and lower AF readmission (subdistribution hazard ratio, 0.85-0.89; P < .05).
CONCLUSIONS: Nearly one-half of patients with AF who underwent CABG receive no treatment. Epicardial ablation was associated with superior long-term survival, and all strategies with were associated lower stroke risk.
