Increased left atrial dimension and elevated postoperative levels of inflammatory and oxidative stress markers (IL-6, IL-8, and SOD) are independent predictors of new-onset atrial fibrillation after CABG in elderly patients.
Khokhlunov S Mikhaylovich (2016) conducted an observational in Coronary artery disease (n=81). Left atrium dimension > 39 mm vs. Left atrium dimension ≤ 39 mm was evaluated on New-onset postoperative atrial fibrillation (POAF) (OR 2.1, 95% CI 1.2-3.8, p=0.0004). A left atrium dimension greater than 39 mm independently predicted the development of new-onset postoperative atrial fibrillation (OR 2.1) in elderly patients after coronary artery bypass graft.
