Purpose of review

Although obstructive sleep apnea (OSA)-associated pulmonary hypertension is not uncommon and carries a worse prognosis if left untreated, it is less well recognized by clinicians. This review provides information on prevalence, pathophysiology, clinical presentation, treatment, and prognosis of pulmonary hypertension in OSA.

Recent findings

The prevalence of pulmonary hypertension in OSA ranges from 17 to 53%. The underlying pathophysiology is complex and yet to be fully understood. Continuous positive airway pressure has been proven to be efficacious in the treatment of OSA-associated pulmonary hypertension.


There is still lack of research in this field. We look forward to more well designed studies to help us understand this disease entity better.
