Available studies and information on the regulatory effect of the autonomic nervous system (ANS) in pregnancy are insufficient and contradictory due to a variety of research methods of ANS, the lack of a single standardized approach to the assessment of the functional tone of the ANS departments, and interpretation of the results. The aim of the study is investigation and predictive assessment of clinical and laboratory data in pregnant women with suprasegmental autonomic dysfunction with or without hypertension to determine the main directions of effective prevention of the nervous system damage. The material of the study included 206 pregnant women diagnosed with the syndrome of autonomic dysfunction in different variants. Age ranged from 17 to 47 years. All pregnant women had the following laboratory tests: general clinical tests, biochemical blood tests, including prothrombin index, fibrinogen, von Willebrand factor activity. The clinical and laboratory data were analyzed in pregnant women with autonomic dysfunction with or without hypertension. According to the results, it was found that in all groups of pregnant women a sympathetic effect prevails. This study showed that in the group of normotensive pregnant women, the main symptom is venous dysfunction, which poses a risk of an adverse course of cerebrovascular disease.
