Preoperative Left Atrial Strain Reservoir and the Risk of Postoperative Atrial Fibrillation After Major Lung Resection: A Prospective Single-Center Study
Main finding · POAFResult — go to the resultHazard ratio 9.28 95% CI 3.28–26.24Authors' conclusion
In patients undergoing major lung resection, preoperative LASr assessment may help identify those at low risk of POAF. LASr ≥ 33% was associated with a very low likelihood of POAF
Study context
- Population
- Adults scheduled for major lung resection, tertiary university hospital in France, September 2021–September 2023
- Participants
- 156 adults
- Exposure
- Preoperative LASr < 33% vs ≥ 33%
- Outcome
- POAF
