[Obstructive sleep apnea syndrome. Diagnostic strategies in various clinical settings]

Obstructive Sleep Apnea Syndrome (OSAS) is a common disease, whose prevalence and expression may vary depending on the associated pathology, age or gender. Thus, the prevalence of OSAS is up to 80% in case of refractory hypertension. This led up to individualize clinical presentation of clusters, although currently, the individualization of these different phenotypes did not conduct to a specific care or predict different evolution. Offering the best strategy for the right patient remains an important objective. However, the frequent association of OSAS and various metabolic diseases, and thus induced cardiovascular risk factors, is to be considered in the therapeutic care and judgment of the response to established treatments. By acting on all components in pathological cause in these patients with OSAS, a combined support will thus permit optimal beneficial effect.
