Patients with Coronary Artery Disease or At High Cardiovascular Risk: Measuring Compliance with Treatment for Obstructive Sleep Apnea Syndrome

Recruiting now

Conditions studied: Obstructive Sleep Apnea, Coronary Disease, Cardiovascular Diseases

In brief

Obstructive sleep apnea (OSA) is a sleep disorder characterised by partial or total obstruction of the oro-pharyngeal carrefour during sleep. It is found in between 4% and 25% of the general population and in 40 to 80% of patients with cardiovascular diseases. Continuous positive airway pressure (CPAP) is the standard treatment for OSA and its efficacy has already been demonstrated in this particular population. However, this treatment is not always accepted or sufficiently tolerated. The mandibular advancement device (MAD) is therefore an alternative treatment for OSA, validated by the French National Authority for Health and particularly relevant in this population because it is generally better tolerated. The aim of our study was to assess compliance, tolerance and usability of CPAP and MAD in patients with coronary artery disease and moderate (Apnea-Hypopnea Index AHI 15-30) to severe (AHI\>30) OSA.

You may qualify if…

• Target population: with coronary artery disease or at very high risk of coronary artery disease:
• Patients with coronary artery disease with or without co-morbidities (smoking, diabetes, hypertension, dyslipidaemia, renal insufficiency, overweight, emerging factors including anxiety-depression, shift workers, etc.).
• Hypertensive patients at high cardiovascular risk (target organ damage such as LVH or albuminuria)
