Impact of non-dipping on cardiovascular outcomes in patients with obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) is a risk factor for cardiovascular events. However, it is unclear how OSAS contributes to the events. We investigated the impact of non-dipping on the incidence of cardiovascular events in a retrospective cohort study comprising 251 patients with OSAS.

The relationship between morning hypertension and sleep quality in patients with obstructive sleep apnea syndrome.

This study aimed to investigate the prevalence of abnormal diurnal blood pressure (BP) profiles in patients with obstructive sleep apnea syndrome (OSAS) in relation to the data of a sleep study. Total 103 patients newly diagnosed with OSAS underwent overnight polysomnography and 24-hour ambulatory BP measurements. Patients without morning or nocturnal hypertension (control group), patients with morning hypertension but not nocturnal hypertension (surge-type group), and patients with both morning and nocturnal hypertension (sustained-type group) were compared.
