Description
Summary:Introduction Obstructive sleep apnea (OSA) is a common disorder with important clinical consequences. Many studies have proven that OSA is one of the most important causes of secondary hypertension. Masked hypertension (MH) is defined as a presence of normal office blood pressure together with abnormal results in 24 h ambulatory blood pressure monitoring (ABPM). The prevalence of this condition in patients with OSA is not well defined. Continuous positive airway pressure (CPAP) is the most effective method of OSA therapy. The influence of CPAP therapy on prevalence of masked hypertension is not well known. The aim of this study was to evaluate the influence of CPAP therapy on prevalence of MH in patients with OSA. Materials and methods 43 patients (40 men) were included, average age 54.2 ± 10.5. All of these patients were evaluated using polysomnography with diagnosis of OSA, average apnea-hypopnea index (AHI) 60.6 ± 23.6. Patients were treated with CPAP for one year. Patients with low compliance (CPAP usage
