Brief Summary:
Evaluation of the effect of CPAP (continuous positive airway pressure ) treatment in PAH (pulmonary arterial hypertension) and CTEPH (chronic thromboembolic pulmonary hypertension) patients suffering from sleep disordered breathing.

Condition or disease Intervention/treatment Phase
Sleep-Disordered Breathing Pulmonary Arterial Hypertension Chronic Thromboembolic Pulmonary Hypertension Device: CPAP Not Applicable

Detailed Description:

The primary endpoint of the study is to evaluate the effect of CPAP therapy on pulmonary vascular resistance in PAH and CTEPH patients suffering from sleep disordered breathing.

The secondary endpoints are the effect of CPAP on right atrium and right ventricle diameter and ejection fraction measured by echocardiography, 6 minutes walk distance, NYHA class, QOL, endothelial function, sympathetic activity and prognosis.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 44 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Sleep Disordered Breathing in Precapillary Pulmonary Hypertension: Effect of CPAP Treatment
Study Start Date : April 2014
Estimated Primary Completion Date : April 2019
Estimated Study Completion Date : April 2019

Arm Intervention/treatment
cpap treatment
patients randomized to the 'no cpap' arm will not be treated by CPAP
Device: CPAP
Treatment with CPAP for six months in the CPAP arm.

No Intervention: no cpap
patients randomized to the 'cpap' arm will be treated by CPAP

Primary Outcome Measures :
  1. Change in PVR (pulmonary vascular resistance) [ Time Frame: change in PVR from inclusion at 6 months ]
