Key result
Old age (OR 1.062, p=0.000) and low ejection fraction (OR 0.980, p=0.008) were independent risk factors for postoperative atrial fibrillation, which occurred in 30.94% of patients after isolated CABG.
Why the study?
Postoperative atrial fibrillation is a common complication after CABG that prolongs hospitalization and increases expenses, and perioperative risk factors may predict its occurrence.
What are the independent risk factors for postoperative atrial fibrillation in patients undergoing isolated CABG?
Population
6229 patients in preoperative sinus rhythm undergoing isolated CABG
Comparison
Patients with POAF vs patients without POAF
Design
Retrospective study

May identify perioperative POAF predictors for risk stratification; leaves open prospective validation before guiding prophylaxis.

What are the independent risk factors for postoperative atrial fibrillation in patients undergoing isolated CABG?
Odds Ratio: 1.062
p-value: p=0.000
Old age and low ejection fraction are independent risk factors for postoperative atrial fibrillation after isolated CABG, which occurs in approximately 31% of patients.
Zhou et al. (2024) conducted a cohort in Postoperative atrial fibrillation after CABG (n=6,229). Old age and low ejection fraction was evaluated on Postoperative atrial fibrillation (POAF) (OR 1.062, p=0.000). Old age (OR 1.062, p=0.000) and low ejection fraction (OR 0.980, p=0.008) were independent risk factors for postoperative atrial fibrillation, which occurred in 30.94% of patients after isolated CABG.
