Objective. To study heart rhythm variability (HRV) in ethnic groups of pregnant women with and without arterial hypertension during all gestation period. Design and methods. 100 pregnant Russian and Buryat women with arterial hypertension formed the main group. The control group included 100 healthy pregnant women with a normal current of pregnancy, without arterial hypertensions. All subjects underwent Holter ECG monitoring («Incart», «Kardiotechnika-04-BP-3», Russia). Results. There is a significant decrease in time parameters of rhythm variability n pregnant Buryat women with arterial hypertension in the second trimester. In the third trimester of pregnancy heart rhythm variability is higher in hypertensive women compared to those without hypertension. In Russian population indicators of heart rate variability do not vary during the day. In an ethnic group of women with arterial hypertension an increase of indicators of low and high frequencies due to the prevalence of vascular sympathetic regulation is observed in the first trimester of pregnancy. Conclusions. Pregnant women of the Buryat population with arterial hypertension have lower heart rhythm variability in the first and second trimesters of pregnancy. In Russian population the variability parameters do not change.

Objective. To analyze heart rhythm variability, hemodinamics, pro- and anti-inflammatory plasma cytokines production in pregnant women. General clinical examination was carried out in both groups, echocardiography, Holter monitoring with subsequent calculation of generally accepted heart rate variability indices were performed. The circadian heart rate index (ratio day/night) was calculated. It was found that pregnancy-induced hypertension was accompanied by impaired cytokine balance. Altered immune homeostasis has been established to be a leading factor in the pattern of gestational complications.

The objective of this work was to study circadian rhythms of the indicators of the spectral analysis of the heart rate variability in case of depression. Materials and methods. A total of 37 patients, with a mean age of 46.7±10.3 years, were examined. According to the International Classification of Disease, 10th revision (ICD-10), endogenous depression was diagnosed for all of them (F 31.3–31.4, F 32.0–32.2, F 33.0–33.2). To assess the variability of the heart rhythm, the spectral analysis was used. The patients were examined at 1 AM, 7 AM, 1 PM, 7 PM prior to the beginning of treatment, following one week, and upon leaving the inpatient department. The control group consisted of 15 mentally healthy people. Results. Before the beginning of treatment, desynchronization of circadian rhythms of the indicators studied and the sleep-wake cycle, the increase in the spectrum power within lowfrequency (LF) range, and the decrease in the spectrum power within high-frequency (HF) range were observed. Reduction of depression symptoms was followed by resynchronization of the rhythms under study, with a spectrum power within LF range being increased and that within HF range – decreased. Conclusions. Changes in depression symptoms and chronobiological disorders testify to their close pathogenetic link.

Adaptive Reactions

According to modern data, the cardiovascular system is a kind of indicator of the organism's adaptive activity, and the structure of the heart rhythm carries information about the development of adaptive reactions in response to irritating factors of the external and internal environment.The aim of the study – to investigate the functional state of the autonomic nervous system in pregnant women who have harmful habits by evaluating and analyzing the parameters of heart rate variability in order to prevent complications of non-delivery of gestational process.Materials and Methods. The study involved 73 pregnant women, 53 of them were pregnant (the main group) who had malignant habits in history. Before studying adaptive reactions in pregnant women, a study of cardiac rhythm variability was performed in practically healthy non-pregnant women of reproductive age (25.3±2.2) years). The control group consisted of 20 pregnant women without any harmful habits. Determination of heart rate variability was performed on the basis of peripheral heart rate recording, which included measuring the sequence of RR intervals for 5 minutes, followed by mathematical analysis using the PlsMntr software product.Results and Discussion. It was established that in the main group, in the complicated failure to pass the gestational process, violations of cardiac rhythm variability were detected in 59.7 % of cases. There is an increase in the frequency of very low frequency (VL F) waves (43.5 % relative to control, p<0.05), indicating a predominance of humoral and metabolic rate of regulation of the cardiac rhythm. At the threat of premature births, a decrease in the particle (LF) is observed at 36.6 %, a decrease in the share of high-frequency waves (НF) by 30.8 %. Taking into account the results of the study, one can speak of a decrease in the tone of the sympathetic and parasympathetic nervous system, reducing the influence of the reflexive vegetative level of regulation, which, in turn, indicates the depletion of regulatory mechanisms and the lack of an adaptive protective effect of n.vagus on the heart.Conclusions. Our innovative low-invasive method of evaluating the adaptive reactions of the organism through the determination and analysis of indicators of cardiac rhythm variability in pregnant women with the existing harmful habits offers us the opportunity to observe manifestations of functional stress of regulatory systems of pregnant women, preceding the development of complication of non-delivery of gestational process.

Background. Searching for new strategies for the rehabilitation of adolescents with obesity and comorbid arterial hypertension (AHT) before significant pathological changes development in the cardiovascular system remains the urgent challenge. Objective. The aim of the study was to examine the effect of interval hypoxic training (IHT) on blood pressure (BP) levels in adolescents with overweight / obesity and comorbid AHT. Methods. Adolescents aged 14-17 years with body mass index SDS ≥ 1 and grade I AHT (mean level of systolic and/or diastolic BP ≥ 95th percentile for population of corresponding age, sex and height) have been randomized to the group «aerobic training» (treadmill walking) and “aerobic training + IHT” (usage of hypoxicator in intermittent operation cycles). All patients were on subcaloric diet (10% reduction in caloric intake for given age). Primary outcome measure was the difference between groups on systolic/diastolic BP levels according to 24-hour BP monitoring after completion of training program (10 classes each). The effects of IHT on body composition (bioelectrical impedance analysis), heart rate variability and psychoemotional state (Spielberger scale, assessment of health, activity and mood) were further estimated. Results. 43 patients were assigned to the index group, and 42 — to the control group. 67 patients have completed the research program. 5 patients (12%) from the IHT group and 13 patients (31%; p = 0.029) from the control group prematurely discontinued participation in the trial due to poor exercise tolerance. The groups were comparable in baseline systolic and diastolic BP. Decrease in BP occurred in both groups after 10 workouts. There were no differences in decrease value: mean difference for SBP was 2.4 mm Hg (95% CI -6.6 ... 1.8), for DBP — 0.2 mm Hg (-3.6 ... 4.0). However, the incidence of reaching the targeted SBP (< 95th percentile for the corresponding age and sex) after completion of the treatment was recorded in 66% patients in the experimental group and in 42% patients in the control group (p = 0,047). Positive dynamics in several indicators of heart rate variability and psychoemotional state were mentioned in the IHT group. Conclusion. The IHT implementation in the complex of rehabilitation program for adolescents with overweight / obesity and AHT has no additional positive effect on BP levels. However, the incidence of reaching the targeted SBP (< 95th percentile for the corresponding age and sex) after completion of the treatment was recorded in 66% patients in the experimental group and in 42% patients in the control group (p = 0,054).

The article discusses the use of a neural network analysis of heart rate variability for the diagnosis of immobilization syndrome and post-intensive care syndrome (PICS) in patients with disorders of consciousness for monitoring the quality of the rehabilitation process. It is shown that there are statistical differences between the curves characterizing the heart rate variability of healthy patients and patients with impaired consciousness. The use of a neural network allows to automatically evaluate the severity of the immobilization syndrome and Post Intensive Care Syndrome, as well as the effectiveness of measures for their prevention and the overall quality of the work of medical personnel.

The aimof the study was to analyze the impact of the status of cardiac autonomic nervous regulation on the fragmentation activity, development and progression of heart failure, and the long-term prognosis in patients with early ST segment elevation myocardial infarction.Material and Methods. The study included 143 subjects; 54 healthy volunteers were examined to identify normal values of heart rhythm variability parameters. The observation group comprised 89 patients with ST segment elevation myocardial infarction who underwent 24-hour ECG monitoring at day 7 to 9 as well as at 24 and 48 weeks with follow up assessment of heart rate variability and late ventricular potentials. At the time points, the levels of brain natriuretic peptide and highly sensitive C-reactive protein were determined. Patients underwent a 6-min walk test every 12 weeks. The development of repeated cardiovascular events has been monitored as an end-point. Patients were assigned to two groups according to results of heart rhythm variability analysis at day 7–9 after onset of ST segment elevation myocardial infarction: group 1 had normal heart rate variability; group 2 had increased sympathetic impact on rhythm.Results. In group 1, a pronounced regression of the brain natriuretic peptide level was registered 24 week after onset of ST segment elevation myocardial infarction. The value of C-reactive protein decreased in all groups. A favorable transformation of the indices reflecting the fragmentation activity — high-frequency low-amplitude and root mean square — of the myocardium was recorded only in the group with normal heart rate variability parameters. The risk of repeated cardiovascular events during 48 weeks after ST segment elevation myocardial infarction was significantly higher in the group with dominant sympathetic activity than in the group with normal status of the autonomic nervous system.Conclusion. Hypersympathicotonia in the acute period of ST segment elevation myocardial infarction was associated with an increased relative risk of repeated cardiac events and negatively affected the dynamics of laboratory parameters indicative of heart failure development and progression.

Objective. The high prevalence of obesity in employable population dictates the necessity for preclinical diagnosis of diseases associated with it, including the study of the autonomic regulation of heart rhythm. The objective was to study the correlations between the adipocytokine profile and heart rate variability in patients with obesity. Materials and methods. 300 persons were examined, the average age was 46.2 6.4 years; Group 1 was metabolically unhealthy obesity phenotype (MUHOP) 90 patients; group 2 was obesity without metabolic disorders [Ob(+)MD(-)] (MHOP) 50 persons; the control group consisted of 100 healthy respondents. We studied the following indices: blood serum adipocytokines: leptin, insulin, resistin, adiponectin. Heart rate variability was studied using Poly-Spectrum Rhythm 2012 computer electrocardiograph. Results. In the course of the study, decrease in the total heart rate variability and reactivity of the parasympathetic part of the autonomic nervous system in patients from MUHOP group was found, while there were no differences with the control in the MHOP group. It was established that a decrease in the parasympathetic effect on the regulation of heart rhythm is associated with the presence of abdominal obesity, insulin resistance, and an increase in the level of TG, glucose, resistin, and uric acid. Conclusions. The received relationships between indicators of carbohydrate and lipid metabolism, the level of uric acid and adipocytokines with temporal and spectral characteristics of the autonomic nervous system confirm their contribution to the development of autonomic dysfunction in obese persons.

BACKGROUND: Despite the wide prevalence of arterial hypertension in modern society, including in the Russian population, patients sometimes do not suspect the presence of the disease, and among patients with an established diagnosis, drug therapy has low effectiveness. AIMS: Of the study was to study the effect of dry carbon dioxide baths and ozone therapy on heart rate variability and reocardiography in patients with hypertension. MATERIALS AND METHODS: We observed 71 patients with stage I hypertension and grade 12 arterial hypertension. Patients were randomly selected into three groups: in the control group (n=18), patients received complex spa treatment, including diet, physical therapy, massage of the collar area and aromatherapy; in the comparison group (n=20) basic spa therapy and dry carbon dioxide baths; in the main group (n=33) basic spa therapy, ozone therapy and dry carbon dioxide baths. RESULTS: The combined use of dry carbon dioxide baths and ozone therapy in the complex treatment of patients with hypertension in sanatorium conditions is accompanied by a significant improvement in heart rate variability and central hemodynamics. CONCLUSION: Complex spa treatment of patients with hypertension with the additional appointment of dry carbon dioxide baths and ozone therapy helps to reduce the tension of the central mechanisms of regulation of the cardiovascular system, restore vegetative balance and vascular tone.
