Introduction: Obstructive sleep apnea (OSA) is considered as a risk factor for the development and worsening of compensation of arterial hypertension and other cardiovascular diseases. Prevalence of masked and nocturnal hypertension can have a significant negative impact on these patients and these prevalences are not well known.

Aim: To evaluate the prevalence of masked and nocturnal hypertension in patients with OSA.

Materials and methods: In this study, 97 (88 men) patients were enrolled, average age 53.9 ± 9.7 years. OSA was diagnosed with polysomnography and the continuous positive airway pressure therapy has been indicated according to current guidelines. Parameters of OSA (apnea-hypopnea index (AHI), oxygen desaturation index (ODI), % of sleep time
