The task of the study was to elucidate the effect of moderate exercise on heart rate variability (HRV) in women who regularly take kinesitherapy courses. Materials and methods. Studies were conducted on 72 women with essential hypertension (EH), divided into 2 subgroups: first (EH-1) included 37 women suffering from stage II EH and under medical therapy, the second (EH-2) consisted of patients who underwent along with medication treatment, regular courses of kinesitherapy. To evaluate the characteristics of HRV, a photoplethysmography method was used. The following indicators were used: SDRR is the standard deviation of all cardiointervals, RMSSD is the square root of the average sum of squares of cardiointerval differences, LF - is the oscillation power in the low frequency range, due to the activity of the sympathetic section, HF - is the power in the high frequency range, associated with respiratory movements and caused by vagal activity, LF/HF - is the power ratio, reflecting sympathetic balance, CVI - nonlinear parasympathetic index, CSI - nonlinear sympathetic index. Results. It was established that the average heart rate in women of both groups is approximately the same, while all other indicators (with the exception of LF/HF and CSI) were significantly higher in patients EH-2 group. In patients EH-2 group, there is a significantly larger value of SDRR, RMSSD, LF, HF. In the frequency analysis, no increase in the total power of cardiointerval oscillations and autonomic balance (LF/HF) was detected. A pronounced increase in the nonlinear parasympathetic index (CVI) has been shown, while the sympathetic index (CSI) remained unchanged. Conclusion. Regular use of kinesitherapy courses helps to increase the tone of the parasympathetic division of the autonomic nervous system, which is significantly depressed in EH.
Objective. To investigate the effect of the quantitative ratios of different types of white blood cells on the cardiovascular system in healthy individuals and patients with essential hypertension (EH). Materials and methods. The study was performed on 102 women suffering EH. The control group consisted of 30 healthy patients. Results. In women with EH, both non-engaged (EH-1) and regularly engaged in kinesitherapy (EH-2), compared with the control group, the total content of leukocytes was increased, as well as the ratios of NEUTR/EOS, LYM/EOS, LYM/BAS and EOS/BAS. In hypertensive patients increased stroke volume and end-diastolic left ventricular volume, cardiac output, increased mass and the index of left ventricular mass. In EH-1 patients group, the balance of velocity distribution in the microcirculatory bed changes to fast interlayer processes. In patients with EH-2, these changes are much less pronounced. In healthy women and patients with EH, significant relationships between leukocyte ratios and the level of systolic diastolic, mean, pulse pressure, cardiohemodynamics, hemodynamic indices were found. Conclusion. Regular practice of kinesitherapy brings the condition of cardiohemodynamics, hemodynamic indices, as well as the investigated correlations to the characteristic of healthy women. These data suggest an important role of the relationship of various leukocyte populations in the pathogenesis of EH.
