Relationship of vascular complications with endothelial and autonomic dysfunction in patients with obstructive sleep apnea

Abstract

Obstructive sleep apnea is a common pathological condition associated with the occurrence of cardiovascular diseases. The article describes the features of the autonomic (vegetative) nervous system and vascular endothelial function in the examined groups. The paper shows the parameters of heart rate variability, which can be markers of depletion of the body's regulatory systems, a decrease in the adaptation reserve, and the likelihood of developing acute cerebrovascular accident and chronic cerebral ischemia in patients with moderate and severe obstructive sleep apnea.
