Obstructive Sleep Apnoea
Conditions
Brief summary
The aim of the study was to determine the long term effects of compliance with positive airway pressure therapy on blood pressure in both hypertensive and normotensive patients with obstructive sleep apnoea hypopnoea syndrome.
Detailed description
Scientific data about the causal role of obstructive sleep apnoea hypopnoea syndrome (OSAHS) in the development of systemic hypertension and the effects of positive airway pressure (PAP) treatment on blood pressure (BP) control are continuously increasing; however they are controversial. We aimed to determine the long term effects of compliance with PAP therapy on BP in both hypertensive and normotensive patients with OSAHS.
Interventions
Positive Airway Pressure (PAP) is a non-invasive machine providing air pressure f to prevent the collapse of the oropharyngeal walls and the obstruction of airflow during sleep, which occurs in obstructive sleep apnea hypopnea syndrome.
