Fisiopatología de la hipertensión asociada al síndrome de apnea obstructiva del sueño: Evidencia de estudios clínicos y modelos animales de hipoxia crónica intermitente
There is a well established relationship between the obstructive sleep apnea syndrome and hypertension. Current evidence suggests that the increase in arterial pressure is secondary to an enhanced sympathetic tone through peripheral chemoreflexes triggered by intermittent hypoxic stimulation of the...
