RELATIONSHIP OF PARAMETERS OF CENTRAL HEMODYNAMICS AND ARTERIAL STIFFNESS WITH COGNITIVE FUNCTIONS IN PATIENTS WITH ESSENTIAL HYPERTENSION

Objective: To conduct a correlation analysis of central hemodynamics and arterial stiffness parameters with cognitive functions in patients with essential hypertension (EH). Design and method: The study included 111 male and female patients with grades I–III AH according to the classification (ESC/ESH, 2018). The average age of the patients was 54.6±10.8 years, the average duration of AH was 8.8±5.52 years. The state of arterial stiffness was assessed by applanation tonometry using the SphygmoCor apparatus (AtCor Medical, Australia). Cognitive functions were assessed using neuro-psychological tests: the Mini-Cog test (drawing a clock, reproducing words) and the Montreal Cognitive Assessment Scale (MOCA). Results: The correlation analysis between the parameters of central hemodynamics and arterial stiffness revealed a negative correlation between the pulse wave velocity (PWV) and the severity of cognitive impairment, in particular, with the overall Mini-Cog score (R=-0.24, p=0.01), as well as central pulse pressure (CPP) with a total score on the Mini-Cog test (R=-0.27, p=0.007). Conclusions: Thus, an increase in pulse wave velocity and central pulse pressure correlates with the severity of cognitive impairment in EH patients.
