British research suggests that continuous positive airway pressure (CPAP) therapy appears to improve structural and functional changes in left ventricular (LV) function that result from moderate-to-severe obstructive sleep apnea (OSA). The study noted that CPAP therapy resulted in a reduction of posterior wall thickness, and an improvement in LV ejection fraction, systolic velocity, and diastolic LV impairment parameters among patients with OSA.
