Peculiarities of hemodynamics in students with different levels of emotional balance depending on the type of their nervous system

The aim of this paper is to study correlations between the anxiety level and hemodynamic parameters, as well as correlation relationships between hemodynamic parameters depending on the primary vegetative tonus in young people. Materials and Methods. The study enrolled 47 students of the medical university (34 females and 14 males) aged 19-23. The mean age of students was 20.0±1.2 years. Spielberger-Hanin test was used to determine the anxiety level. An oscillometric method was used for blood pressure measurement (OMRON automatic blood pressure monitor, ESH/ESC protocol). The authors measured stroke volume, minute blood volume, mean hemodynamic blood pressure, cardiac index, and specific peripheral vascular resistance. Methods of correlation analysis were used to examine the tested indices. Statistical processing of the obtained data was carried out using computer packages Excel and Statistica Advanced 10 for Windows RU. Results. It was established that 23.42 % of university junior students have a very high (>45 points) reactive anxiety level. The average reactive anxiety level as a whole was 40.0±1.2 points. A high level of personal anxiety (46-71 points) was detected in 36.17 % of students. A higher level of reactive anxiety was detected in persons with dominance of the sympathetic department. A high level of personal anxiety was detected in 45.83 % of students with dominance of vagotonic type of involuntary nervous system. Correlation between anxiety and hemodynamic parameters depend both on the anxiety level and the dominant type of vegetative regulation. The highest degree of correlation was found between the anxiety level and hemodynamic parameters in persons with vagotonic type of vegetative regulation. Conclusion. A correlation was established between the anxiety level and the functional state of central hemodynamics. The difference in correlation of central hemodynamics parameters depended on a primary vegetative tonus.
