Improving sleep apnea does not reduce left heart enlargement in obese people during a weight loss program
Updated
Abstract
Participants with obesity and obstructive sleep apnea had a larger left atrial area (22.4 ± 5.6 cm²) compared to those without obstructive sleep apnea (18.8 ± 3.8 cm²; P = .008).
- Obstructive sleep apnea (OSA) is associated with increased left atrial () area in individuals with severe obesity.
- Average weight reduction after 12 months was 19.0 ± 15.7 kg among participants.
- A significant decrease in the (ΔAHI of -12 ± 14) was observed in participants with OSA after weight reduction.
- Despite improvements in OSA following weight loss, the left atrial area did not significantly decrease.
- No significant associations were found between changes in AHI or body mass index and changes in left atrial area.
