Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for hypertension and cardiovascular disease. OSAS is the frequent underlying disease of secondary hypertension and resistant hypertension. OSAS increases both daytime and night-time ambulatory blood pressures through the activation of various neurohumoral factors including the sympathetic nervous system and the renin–angiotensin–aldosterone system. In particular, OSAS predominantly increases ambulatory BP during sleep compared with the awake period, with the result that OSAS is likely to be associated with the non-dipping pattern (diminished nocturnal BP fall) or riser pattern (higher sleep BP than awake BP) of nocturnal BP.If you have the Symptoms of Sleep Apnea Syndrome--Hypertension, we would say herbal medicine is a safe and effective form of treatment.
