Sleep-Disordered Breathing in Chronic Thromboembolic Pulmonary Hypertension

There is evidence for a high prevalence of Sleep Disorder Breathing (SDB) in patients with Chronic Thromboembolic Pulmonary Hypertension (CTEPH). Central Sleep Apnea, Cheyne-Stokes Breathing and Obstructive Sleep Apnea appear to occur in CTEPH. However, there is no information on the impact of CTEPH treatment modalities on concomitant SDB. Furthermore, the use of PAP therapy in CTEPH has not yet been investigated. CTEPH is a rare and serious disease and there may be a bidirectional association of SDB and CTEPH.

This study plans to investigate the prevalence of SDB in CTEPH and compare it to datasets of large epidemiological studies on SDB. Furthermore, the impact of CTEPH treatment on SDB will be analyzed and CTEPH patients for possible PAP treatment will be defined.

Treatment and study plan

Riociguat

Drug

Patients will be treated with Riociguat according to guidelines (2015 ERS/ESC guidelines for the diagnosis and treatment of pulmonary hypertension) and manufacturers recommendation.

Other names: Adempas

Pulmonary Endarteriectomy

Procedure

Patients will receive Pulmonary Endarteriectomy if they are suitable for this procedure according to the recommendation of the local CTEPH board. Patients must also consent to this surgical procedure.

Other names: PEA

Ballon Pulmonary Angioplasty

Procedure

Patients will receive Ballon Pulmonary Angioplasty if they are suitable for this procedure according to the recommendation of the local CTEPH board (e.g. not suitable for PEA). Patients must also consent to this procedure.The BPA will be accomplished in several interventions.

Other names: BPA

Primary outcomes

  1. AHI change under CTEPH treatment

    Time frame: 6 months

    Change from baseline AHI (Apnoe-Hypopnoe Index, events/h) after 6 months of CTEPH treatment

Secondary outcomes

  1. Number of patients with persisting elevated AHI (= ≥15/h) after CTEPH treatment

    Time frame: Time point: 6 months after the individual start of the CTEPH treatment

    Patients with persisting elevated AHI will be assessed for further PAP treatment
