Objective: Frequent hypoxic episodes and arousal during sleep in obstructive sleep apnea syndrome (OSAS) result in increased nocturnal blood pressure, which in turn may lead to sustained hypertension. Patients with severe OSAS exhibit attenuated nocturnal blood pressure (BP) dipping, as well as marked and rapid BP elevation in the morning shortly after waking. We examined the prevalence of masked hypertension and morning BP surge in patients with OSAS, and the relationship between the severity of OSAS and abnormal circadian BP patterns.
Methods: We performed 24-hour ambulatory BP monitoring in the absence of anti... view more»
