Key result
In patients undergoing isolated off-pump coronary artery bypass grafting, a BMI >31 (OR 3.67), hypertension (OR 3.08), and left atrial size were significant independent predictors of post-operative atrial fibrillation.
Why the study?
Post-operative atrial fibrillation occurs in 20% to 40% of patients after CABG, but a universal pathophysiological concept describing its development is lacking.
Cohort (n=543)
No
Effect estimate: OR 3.6687 (95% CI 2.0554-6.5483)
p-value: p=<0.0001
Left atrial size, hypertension, and a BMI > 31 are significant independent predictors of new-onset atrial fibrillation following off-pump coronary artery bypass grafting.

Guni et al. (2023) conducted a cohort in Post-operative atrial fibrillation (POAF) (n=543). Risk factors (BMI >31, Hypertension, Left Atrial size) vs. Patients without risk factors was evaluated on New-onset post-operative atrial fibrillation (POAF) (OR 3.6687, 95% CI 2.0554-6.5483, p=<0.0001). In patients undergoing isolated off-pump coronary artery bypass grafting, a BMI >31 (OR 3.67), hypertension (OR 3.08), and left atrial size were significant independent predictors of post-operative atrial fibrillation.
