NCT01371669

Brief Summary

In the investigators study, and regarding results of small cohorts in the literature, the investigators hypothesize that hypoxemia is frequent in IPAH and CPEPH. The investigators will explore these patients with a one night polysomnography and transcutaneous capnography, searching for hypoxemia and hypercapnia and by determining its physiopathologic mechanisms.

Outcome Measures

Primary Outcomes (1)

  • hypoxemia during the night

    prevalence of nocturnal hypoxemia in IPAH and CPEPH

    at the inclusion

Secondary Outcomes (2)

  • Predictors: physical, functional and hemodynamical data

    at the inclusion

  • Physiopathologic mechanisms: causes of nocturnal hypoxemia: hypoventilation, sleep disordered breathing, shunting, V/Q mismatch

    at the inclusion

Study Arms (1)

IPAH or CPEPH

Idiopathic pulmonary arterial hypertension (IPAH) or pulmonary hypertension associated with chronic post-embolic pulmonary hypertension (CPEPH)

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with IPAH or CPEPH hospitalized in our pulmonary department for a standard follow-up. They have to be in a stable condition, as defined by the New York Heart Association classes for dyspnea and the six minutes walking test. Furthermore, no changes in medical therapy could have been made during the last three months.

You may qualify if:

  • Patient aged 18 to 75 years
  • Patient with IPAH ot CPEPH stable for at least 3 months. Stability is defined by the New York Heart Association classes for dyspnea and the six minutes walking test (6MWT). Furthermore, no changes in medical therapy had occured during the last three months.
  • Patients who signed informed consent

You may not qualify if:

  • Patients with secondary PH associated with other pathologies outside CPEPH ( sclerodermia, systemic lupus erythematous, portal hypertension, chronic HIV infection...)
  • Patients who had a functional and/or a hemodynamic degradation during the last 3 months or a change in pulmonary hypertension treatment
  • Patients with obstructive or restrictive ventilatory disorder with a Ventricular Ejection Fraction \<60% predicted
  • Women without effective contraception
  • Patients with a Body Mass Index above 35 kg/m2
  • Patient not affiliated to a social security scheme
