Left Atrial Strain to Predict Postoperative Atrial Fibrillation in Patients Undergoing Off-pump Coronary Artery Bypass Graft
Authors' conclusion
LAS R is a significant predictor of POAF
Study context
- Population
- Patients undergoing off-pump CABG (off-pump coronary artery bypass grafting (OPCABG)), tertiary care hospital
- Participants
- 103 patients
- Exposure
- Postoperative atrial fibrillation (POAF) vs No POAF
- POAFn = 24
- Outcome
- POAF prediction by left atrial strain (LAS)
