Key result
Women undergoing isolated CABG had a significantly lower adjusted risk of new-onset postoperative atrial fibrillation compared to men (OR 0.75; 95% CI 0.64-0.89).
Why the study?
Does female sex affect the incidence and characteristics of new-onset atrial fibrillation after isolated CABG compared to male sex?

Women undergoing isolated CABG have a significantly lower adjusted risk of developing new-onset postoperative atrial fibrillation and experience shorter AF episodes compared to men.
Filardo et al. (2016) conducted a cohort in New-onset atrial fibrillation after coronary artery bypass graft surgery (n=11,236). Female sex vs. Male sex was evaluated on New-onset post-CABG atrial fibrillation (OR 0.75, 95% CI 0.64-0.89). Women undergoing isolated CABG had a significantly lower adjusted risk of new-onset postoperative atrial fibrillation compared to men (OR 0.75; 95% CI 0.64-0.89).
