Continuous positive airway pressure therapy for patients with obstructive sleep apnea and coronary artery disease

Figure 3 Impact of continuous positive airway pressure therapy on clinical outcomes in patients with obstructive sleep apnea. A: In patients with obstructive sleep apnea without established coronary artery disease (CAD), continuous positive airway pressure (CPAP) therapy reduces the risk of future cardiovascular events. However, in those with preexisting CAD, the prognostic benefit of CPAP remains unproven despite the physiological rationale; B: Among patients already receiving CPAP therapy, continuation is associated with improved survival compared with treatment discontinuation, highlighting the importance of long-term adherence in optimizing patient outcomes. CPAP: Continuous positive airway pressure; CAD: Coronary artery disease; OSA: Obstructive sleep apnea.
