[Progress in research on obstructive sleep apnea syndrome with hypertension]

Obstructive sleep apnea syndrome (OSAS) is a complicated chronic disease caused by certain reasons, characterized by obstruction of the upper airway and apnea or hypopnea during sleep, which can be followed by anoxia, snoring and daytime sleepiness. Recent studies have shown that hypertension is closely connected to OSAS. OSAS can lead to hypertension by several possible mechanisms. The diagnosis of OSAS mainly depends on the medical history, sign, polysomnogram (PSG) result and the frequency of apnea and hypopnea. OSAS can be relieved by continuous positive airway pressure (CPAP), oral orthodontic treatment, medicine, change of lifestyles and others. This brief review focuses on the mechanism of hypertension due to OSAS and the diagnosis criteria and treatment of OSAS.
