Endothelial Dysfunction, Hypertension, Obstructive Sleep Apnea
Conditions
Brief summary
The aim of this study is to examine how effective CPAP treatment and treatment with nebivolol are respectively on reducing blood pressure and on endothelial dysfunction in patients suffering from obstructive sleep apnea and hypertension.
Interventions
8 weeks of Nebivolol treatment (5mg/day)
8 weeks of CPAP treatment
