Abstract
OSAS (obstructive sleep apnoea syndrome) is the most common type of sleep apnoea, characterised by obstruction of the upper airways during sleep, causing the absence or reduction of airflow, although there is respiratory muscular activity. It contributes to the occurrence of multiple complications such as hypertension, obesity, diabetes mellitus, cardiac and cerebral pathology, metabolic damage. The objective of this study was to evaluate the major comorbidities associated with OSAS in a group of 101 clinically diagnosed and polysomnographic patients with OSAS at “Marius Nasta” Institute in Bucharest during 2014-2015. The obtained results revealed a very high prevalence of ENT disorders, hypertension, dyslipidaemia and gastroesophageal reflux. Also, among these patients, there was an increased incidence of rhythm disorders (17.8%), such as RBB, ESSV, FiA, but also of ischaemic heart disease (16.83%).
