Aim. To study the effect of class III antiarrhythmic drugs (amiodarone and sotalol), and the β-blocker bisoprolol on the spectral parameters of heart rate variability in patients with different forms of atrial fibrillation (AF).Material and methods. Spectral analysis of heart rate variability of 5-minute electrocardiography intervals was used. The study included patients with newly diagnosed AF and having a duration of the disease from 6 months to 8 years. Arterial hypertension, coronary artery disease, myocardial infarction (in history), conduction disorders and type 2 diabetes mellitus were diagnosed as comorbidities. The following parameters were calculated: the total power (TP) of the spectrum, the power of very low frequencies (VLF), low frequencies (LF) and high frequencies (HF).Results. In the group of patients with newly diagnosed AF without concomitant diseases after administration of amiodarone, VLF prevails in the spectrum structure, which indicates a significant role of humoral factors in the regulation of heart rate. The power of LF, reflecting the activity of the sympathetic nervous system, prevails over HF power after administration of amiodarone. In patients with newly diagnosed AF, having concomitant diseases, sympathetic influences prevail over parasympathetic ones by 3.6 times after administration of amiodarone. In the group of patients who have reduced the number of comorbidities, the LF/HF decreases and is only 1.66 after administration of amiodarone. The decrease in the number of negative factors is also accompanied by an increase in the influence of the vagus nerve on the activity of the heart. In the study of the effects of sotalol, the LF/HF in this group was twice lower in the group of patients with long-term AF. In patients receiving bisoprolol as antiarrhythmic therapy, the proportion of LF in the group of patients with newly diagnosed AF is 2 times lower, and the proportion of HF is twice higher than in the group of patients with long-term AF.Conclusion. The effect of antiarrhythmic drugs on the spectral parameters of heart rate variability depends on the duration AF. The presence of concomitant diseases of the cardiovascular system can significantly change the effect of antiarrhythmic drugs on the spectral parameters of heart rate variability and is accompanied by an increase in sympathetic activity. In patients with newly diagnosed AF, amiodarone and sotalol cause a similar effect – the predominance of sympathetic influence; when using bisoprolol, the predominant influence belongs to the vagus nerve. In patients with long-term AF, the opposite effect of drugs is observed: the use of amiodarone is accompanied by a more pronounced influence of the vagus nerve, and bisoprolol – the predominance of sympathetic influence. When using sotalol, sympathetic influences also prevail, more pronounced in patients with newly diagnosed AF.

Spectral analysis of heart rate variability gives an idea of the role of the autonomic nervous system in the regulation of chronotropic heart function. This method can be used to evaluate the effectiveness of drug therapy. Drug therapy should be carried out taking into account the individual clinical form of atrial fibrillation. Information about the vegetative status of the patient will undoubtedly increase the effectiveness of treatment. In this study, spectral parameters were studied in patients with atrial fibrillation. The effect of sotalol on the spectral parameters of heart rate variability was studied.

Background: The concept of metabolic syndrome (MetS) as a cluster of risk factors of type 2 diabetes and cardiovascular diseases has undergone some evolutionary transformations over the past years. Integrating the autonomic dysfunction into the pathogenesis of MetS creates the possibility of including a range of nosologies affecting treatment and clinical manifestations of pathologies belonging to MetS into the MetS cluster. The purpose of this work is to determine the involvement of autonomic dysfunction in the pathogenesis of associated pathological conditions in patients and MetS. Methods: A cross-sectional study was conducted. The sample consisted of 158 patients with metabolic syndrome. The patients underwent a physical examination, including BMI; a blood chemistry test with the determination of the hormonal status (insulin, testosterone, dihydrotestosterone); a 24-hour monitoring of blood pressure (BP); an assessment of heart rate variability; studies showing the presence of gastric reflux (рН-measurement) or its damaging impact (endoscopy); men were tested with the IPSSQOL questionnaire and underwent transrectal ultrasound of the prostate and ultrasound of the bladder. Results: It is revealed that because of MetS, the occurrence of cardiac autonomic neuropathy reaches 37.5%. Some features of gastroesophageal reflux disease in patients with MetS are shown. Regurgitation prevails in the structure of complaints. In case of fibrogastroduodenoscopy, an endoscopynegative form of the disease occurs in 38%. According to the data of daily pH-measurement, when DeMeester score is high, in the supine position, 25% of the time accounts for alkaline reflux (рН > 7). It is found out that young men experience the enlargement of prostate volume and size; according to the IPSS questionnaire, the scores correspond to the initial manifestations of hyperplastic diseases of the prostate gland due to insulin resistance and normal level of androgens. Conclusions: The paper demonstrates that the autonomic dysfunction of the nervous system (on a par with insulin resistance) is the main link in the development of MetS. This provides the basis for including the mentioned states – cardiac autonomic neuropathy, lower urinary tract symptoms, and gastroesophageal reflux disease – into the MetS cluster..

Background. Atrial Fibrillation is one of the most common arrhythmias. Despite the different attitude to the pharmacotherapy of Atrial Fibrillation, the problem of selection of adequate antiarrhythmic therapy for the prevention and treatment of persistent Atrial Fibrillation remains relevant and is of great interest to researchers. For the effective selection of drugs in the treatment of arrhythmia can be successfully used the method of spectral analysis of heart rhythm variability. Aims: to study the effect of antiarrhythmic drug Sotalol and β-adrenoblocker Bisoprolol on the spectral parameters of heart rhythm variability in patients with Atrial Fibrillation. Methods. 167 patients with Atrial Fibrillation of both sexes aged 46 to 94 years were examined. The study included patients with the first diagnosed Atrial Fibrillation, and with persistent Atrial Fibrillation during of 6 months to 8 years. Arterial hypertension has diagnosed in all patients. Also, patients were diagnosed with coronary heart disease with a history of myocardial infarction and without myocardial infarction. Spectral analysis of heart rhythm variability was conducted in patients with Atrial Fibrillation. Therapy in patients was performed with the antiarrhythmic drug Sotalol (80−160 mg, orally) and Bisoprolol (2.5−5 mg, orally). Results. Spectral analysis of heart rhythm variability in patients Atrial Fibrillation using Sotalol showed that the proportion of VLF in patients with the first diagnosed Atrial Fibrillation is more than half of the spectrum, whereas in patients with persistent Atrial Fibrillation this parameter is 18%, the proportion of LF is higher in patients with persistent Atrial Fibrillation. The coefficient LF/HF in patients with persistent Arial Fibrillation is two times lower than in patients with the first diagnosed Atrial Fibrillation. Spectral analysis of heart rhythm variability in patients Atrial Fibrillation using Bisoprolol, it was shown that the proportion of LF in patients with the first diagnosed Atrial Fibrillation was 2 times lower, and the proportion of HF was twice higher than in patients with persistent Atrial Fibrillation. Conclusions. In this study, a spectral analysis of heart rate variability in patients with Atrial Fibrillation, who receive antiarrhythmic drug therapy with sotalol and bisoprolol, was carried out. It was found that humoral factors play a significant role in patients with the first diagnosed Atrial Fibrillation during sotalol therapy, the role of the vagus in this group of patients is minimal, while in patients with bisoprolol therapy the vagus has a dominant effect on the activity of the heart.

The use of the spectral analysis of the heart rate variability to assess the effectiveness of therapy is of great attention of researchers and doctors. This method allows you to get knowledge of the influence of the autonomic nervous system on the heart activity, which is an important factor for the manifestation of the effects of antiarrhythmic drugs. In this study, we studied the effect of antiarrhythmic drugs of class III amiodarone and sotalol on spectral indices of the heart rate variability in patients with atrial fibrillation. The power of slow frequencies prevailed in the structure of the spectrum with the introduction of amiodarone and sotalol. This suggests that the sympathetic nervous system have a predominant influence on the heart.

Background: Statins are currently used for secondary prevention of Coronary Heart Disease (CHD), as the lipid-lowering therapy with them is proven safe and effective. Objective: The purpose of this research is to investigate the dose-dependent effect of statins used for secondary prevention of coronary heart disease, as well as mechanisms of quantitative and qualitative changes in lipoproteins, fatty acids and cholesterol in the blood and tissues of people of both sexes. Methods: In a clinical trial (n=125, of which 89 patients belong to group 1 and 36 to group 2) and an experiment on laboratory animals (n = 100), simvastatin reduced the total level of fatty acids in blood plasma, when given in the amount that was within the therapeutic dose range. Results: This effect was achieved through a drug-induced improvement in the capacity of hepatic cells to absorb Low-density (LDL) and Very-low-density (VLDL) lipoproteins. Conclusions: Considering the formation of saturated fatty acids, statin performed better in males. With Omega-3 polyunsaturated fatty acids involved, changes in lipoproteins, cholesterol and fatty acids (liver and myocardium) were similar to those caused by small doses of a statin drug. Effects of the combination of bisoprolol and acetylsalicylic acid were completely different from those caused by the use of statin.

The pathophysiology of the intervertebral discs plays a significant role in the people’s life quality. There is not adequate research done in the pathogenesis and treatment of intervertebral disc degeneration. Alternately, self-educated physiology offers a novel and noninvasive method to reverse the degenerated discs. In this single case study, report attempts have been made to highlight the effect of the self-educative physiology, on magnetic resonance imaging investigations, of progressive healing, on the degenerated intervertebral discs. Based on this novel method, an effort has been made to review literature on the degeneration of intervertebral discs and available mode of treatments and then to propose a hypothesis for the biochemical mechanisms of healing. The idea is that transforming growth factor-β1 from seminal plasma secretions may contribute to releasing the osteogenic protein- 1 which induces nucleus pulposus and annulus fibrosus cells in intervertebral discs for repairs. In addition, the patient’s medical history is presented with background information.

Background: Oxidative stress and amyloid deposition are tightly interconnected pathological features of Alzheimer disease. In this respect, both amyloid production and aggregation may be stimulated by oxidative stress and also the increase of pathogenic β-amyloid and its aggregated form lead to oxidative stress progression. Therefore, the search for potential drugs with both antioxidant and antiaggregation properties are of great interest. Methods: In this study, we described the stereospecific synthesis of alkaloid securinine aminoderivatives. Results: We showed that the newly synthesized compounds possess antioxidant and metal-chelating properties. Indeed, we report that one compound has inhibitory effects towards μ-amyloid aggregation. Conclusion: Based on these results, aminoderivatives of securinine scaffold are promising compounds for development of new drugs for the treatment of neurodegenerative diseases.
