Brief Summary

The high prevalence (9% in men and 4% in women) of sleep apnea / hypopnea syndrome (SAHS) in adults is now well documented as well as its cardiovascular repercussions. Previous studies showed a conclusive link between SAHS and severe cardiovascular diseases such as hypertension, myocardial infarction, heart failure and stroke.Then, SAHS is a public health issue in adults.

In this context, early detection of such a disease is crucial if the management is tailored to the patient, the practitioner's choice of therapy moving towards continuous positive airway pressure (CPAP) or mandibular advancement device. The detection is based on full nocturnal polysomnography or polygraphic recordings. Polysomnography remains the gold standard but it is a time consuming and costly examination. Polygraphic recording is a test that allows simplified the diagnosis of severe patients, but may not be sufficient for mild form of SAHS. Thus, the SAHS is a pathology under-diagnosed and under-treated. The validation of a technique for identifying patients most at risk to either limit the number of polysomnographic examination is requested.

Detailed Description

In this perspective, the development of a product screening sleep related breathing disorders for physicians, cardiologists, internists (not specialized sleep experts) would fill this need. It allows for a reliable first screening for their patients in parallel with a routine cardiological examination. Imposing a minimal human and material, the ECG Holter recorder "VistaO2" (NOVACOR, Rueil-Malmaison, France) is a device designed to meet these requirements. This device fits into the daily management of patients with cardiac arrhythmias or sinus/atrioventricular conduction disorders, and of patients suffering myocardial infarction (arrhythmic risk stratification, detection of silent myocardial ischemia).

Analysis of heart rate variability (HRV) has already shown interest in screening SAHS. We therefore wish to evaluate the performance of the analysis of data from the screening tool VistaO2 face what the gold standard synchronized polysomnography.
