Quality of Sleep of Patients With Predominant Central Sleep Apnea Syndrome(SAS) Whose EF > 45% Treated by ASV (FACIL-VAA)

Observational Multicenter Cohort Study of French Patients With a Central or Combined Syndrome of Sleep Apnea With a Predominant Central SAS Treated by Adaptive Servo-Ventilation

The main goal of this French multicenter observational cohort study is to prospectively collect data assessing the impact of the Adaptative Servo-Ventilation treatment on the quality of sleep of patients with central or combined sleep apnea syndrome (SAS) out of Heart Failure (HF) with altered ejection fraction, with a predominant central SAS.

Study Overview

• Status: Completed
• Conditions: Heart Failure With Preserved Ejection Fraction; Central Sleep Apnea
• Intervention / Treatment: Device: Adaptative Servo Ventilation

Study Population

Patients With Central or Combined Sleep Apnea Syndrome (SAS) Out of Heart Failure (HF) With Altered Ejection Fraction, With a Predominant Central SAS.

Description

Inclusion Criteria:

• Patient over 18 years

• Naive patient to treatment with positive pressure with AHIc > 15 requiring the establishment of an ASV to a central or combined SAS without any systolic HF (LVEF ≤ 45%) with predominant central SAS.

  • OR Patient with a predominant obstructive SAS ( ≤ 50% central event ) whose Continuous Positive Airway Pressure treatment (CPAP) does not allow adequate control of the central events: treated for at least 1 month CPAP with a residual central apnea hypopnea index greater than or equal to 10 events per hour (AHI global> 15, which AHIc ≥ 10) pressure to control obstructive events ( IAHo <5 ) controlled by polygraphy or polysomnography with a pressure test <10 cm H2O.
• Before inclusion, for patients who have previously been treated with CPAP, a PSG diagnosis will be made after a period of wash-out of CPAP of a 1-week period.
• Patient affiliated to the national social security (beneficiary or assignee ).
• Patient being aware of the information form and signed informed consent.

Exclusion Criteria:

• Patients with against -indication for the use of ASV :

  • History of massive epistaxis.
  • Diseases related to barotrauma particularly pneumothorax and pneumo- mediastinum.
  • Suspicions of meningeal gaps or trauma history of the prior stage of the skull base.
  • Shortness of breath or hypercapnia deemed incompatible by the doctor with the ASV treatment.
• Patients with predominant obstructive sleep apnea (OSA) (> 85% obstructive events ).
• Standardized central SAS by the Continuous Positive Airway Pressure
• Patients with a diagnosis of systolic heart failure (LVEF ≤45 %) with a predominant central SAS ( > 50% central events ).
• Person deprived of liberty by judicial or administrative decision, person under a legal protection measure (pregnant or lactating women, patients under guardianship)
• Lack of signature for the information form and the informed consent form.
