Abstrakt: Abstract  Obstructive sleep apnea (OSA) and increased left atrial volume (LAV) both independently increase cardiovascular mortality. We hypothesized that treatment of OSA with continuous positive airway pressure (CPAP) may decrease LAV. We retrospectively identified 47 OSA patients receiving CPAP who had echocardiograms done before and after polysomnography. Compliance was defined as CPAP use at-least five nights weekly and 5 h per night. The compliant group (n = 23) had a significant decrease in diastolic blood pressure (DBP; 4.4 ± 8.9 mmHg, p p n = 24). LAV data were available in 13 compliant and 20 noncompliant patients. LAV decreased nonsignificantly (3.54 ± 16.6 mL, n = 13, p = 0.65) in CPAP-compliant patients, while it increased (15.47 ± 22.3 mL, n = 20, p  [ABSTRACT FROM AUTHOR]
