Key result
Preoperative left atrial dysfunction, indicated by decreased LA strain (10% vs 24%, P<0.001) and strain rate, is an independent predictor of postoperative atrial fibrillation after CABG.
Why the study?
Does preoperative left atrial dysfunction assessed by speckle tracking echocardiography predict postoperative atrial fibrillation in patients undergoing CABG?

May support preoperative LA strain for post-CABG AF risk assessment; leaves open its role in guiding interventions pending prospective studies.
Gabrielli et al. (2011) conducted a cohort in Coronary artery disease undergoing CABG (n=70). Left atrial dysfunction (evaluated by strain and strain rate) vs. Normal left atrial function was evaluated on Postoperative atrial fibrillation (POAF) (p=<0.001). Preoperative left atrial dysfunction, indicated by decreased LA strain (10% vs 24%, P<0.001) and strain rate, is an independent predictor of postoperative atrial fibrillation after CABG.
