ECG Dispersion Mapping in Preclinical Diagnosis of Cardiovascular Diseases.

The aim of the study was to develop a method for diagnosing pre-nosological changes in the electrophysiological state of the myocardium in patients with somatoform dysfunction of the autonomic nervous system (SDANS) and risk factors for cardiovascular diseases using the ECG dispersion mapping method. MATERIALS AND METHODS: The study involved 109 male patients, 58 of them with SDANS, and 51 were healthy subjects. The patients with SDANS had the following risk factors for cardiovascular diseases, in decreasing order: stress (71% of cases), low physical activity (59%), smoking (57%), overweight and obesity (43%), anxiety (41%), low consumption of vegetables and fruit (36%), lack of extra aerobic physical activity (36%), excessive alcohol consumption (34%), depression (26%), total cholesterol ≥5 mmol/L (23%), and heart rate ≥80 (9% of the cases). All the subjects underwent clinical examination, laboratory investigation, ECG, ECG dispersion mapping, heart rate variability monitoring. RESULTS: Using the method of ECG dispersion mapping allowed a way for diagnosing pre-nosological changes in the electrophysiological state of the myocardium in male patients with SDANS, the basis of the pathogenesis of which is formed by the tension of the regulatory systems. Correlation between the total score according to the developed method, the RRNN value after 4 min of staying in orthostasis, and the "Myocardium" integral index has been proved. The diagnostic sensitivity of the proposed method with a threshold score of 8 was 80%, specificity - 70.8%. CONCLUSION: The developed method for assessing pre-nosological changes in the electrophysiological state of the myocardium which includes cardiovascular risk factors with a reclassifying potential, proves the development of pre-nosological changes in patients with SDANS in response to daily physical strain. The changes are associated with the tension of the electrophysiological state of the myocardium, an increased activity of the sympathetic division of the ANS being one of its pathogenetic mechanisms.

[Postoperative cerebral dysfunction]. / Posleoperatsionnaia mozgovaia disfunktsiia.

AIM: To study the structure, risk factors and methods of prevention of postoperative brain dysfunction on the example of coronary artery bypass surgery with cardiopulmonary bypass. MATERIAL AND METHODS: The study included 77 patients who undergone elective coronary artery bypass surgery at the beating heart (22 patients) or with cardiopulmonary bypass (55 patients, including 24 patients, who received cerebroprotective treatment with cytoflavin in the preoperative period). All patients underwent dynamic (pre- and postoperative) neurological, neuropsychological, instrumental examinations. RESULTS: The postoperative cerebral dysfunction was diagnosed in 34 (44,2%) patients. The frequency of the clinical types of postoperative cerebral dysfunction significantly differed: perioperative stroke - 3 (3,9%) cases, symptomatic delirium of the early postoperative period - 11 (14,3%) cases, delayed cognitive impairment - 28 (36,4%) cases. The risk factors of postoperative cerebral dysfunction after the coronary artery bypass surgery with cardiopulmonary bypass were identified. Preventive preoperative use of the neuroprotective drug cytoflavin reduces the severity of delayed cognitive impairment after the coronary artery bypass surgery with cardiopulmonary bypass and has a good safety profile. CONCLUSION: An analysis of the literature data and the results of our own studies show that postoperative cerebral dysfunction is the nosological entity with various etiological factors, pathogenetic mechanisms and the characteristic clinical types, which has an effect on the outcome of surgical treatment.

[Neurophysiologic mechanisms of combat post-extreme state of health].

The effects of ecological and occupational stress (EOS) on brain neurodynamics of Soviet and Afghanistan servicemen have been studied. The investigations have been made in Afghanistan. Neurophysiological characteristics of traumatic stress and consequences of combat trauma were studied in patients wounded in Afghanistan, in the acute phase as well as since 0.5-3 years after leaving the battlefield. The combined effect of combat situation, hot climate, highlands and desert forms EOS. It does not cause an adaptation process in servicemen. EOS is characterized by changes in bioelectrical indices of brain in interhemispheric relations both as a whole and in isolated rhythm components of EEG, by activating the stress limiting system. It exhibits pathopsychological and autonomic components which remain significant during 3 years after leaving the combat conditions. The formation of a general adaptation syndrome is prevented in explosion trauma under the influence of EOS.

[Direct evidences of calcium traffic through pacemaker channel].

Recently, it was shown that pacemaker f/HCN channel might be permeable not only for Na+ and K+, but also for calcium ions. Pacemaker channel HCN2 was expressed in ovarian cell culture of Chinese hamster. In the patch clamp experiments the calcium current with low amplitude 0.06±-0.87 nA and open probability 0.48% (±3.02 at -110 mV, n = 6, Ca2+ 2 mmol) was measured. HCN2-Ca2+ current significantly activated with cyclic adenosinemonophosphate by increasing of open probability and inhibited by specific If-blocker ivabradine. The calcium ion current was also shown in f-channels of neonatal rats ventriculocytes. Thus, the calcium ions conduction through HCN2 and native f-channel at physiological concentrations of extracellular fluid and physiological membrane potentials of cardiomyocytes was demonstrated.

[Regulation of blood circulation in the surgical correction of portal hypertension].

56 patients with portal hypertension were examined who underwent decompressive shunt surgery. Cardiorhytmography and integral rheography body were performed in different stages. In the late postoperative period, there were positive changes in the autonomic regulation of functions: reduced tension index and sympathetic influence on heart rhythm, increases the value of other indicators of heart rate variability. Due to an increase in heart rate and peripheral vascular resistance normalizes blood pressure while reducing the values of cardiac output. There is a further normalization of the reactivity of blood circulation: arterial pressure and vascular resistance during the functional test remained at a constant level of magnitude of shock and cardiac index significantly increased and then decreased to the level of the original values, which corresponds to the reaction apparently healthy. Disorders of regulation, state and reactivity of blood flow in portal hypertension, manifested: 1. Reduction of heart rate variability with a significant increase in sympathetic activity of autonomic nervous system. 2. Reduction of cardiac output and vascular resistance, heart rate, changes in physiological determination of hemodynamic parameters: Blood pressure is determined only by the vessel resistance. 3. Reduction of blood pressure in response to breath holding test.

[Psychoemotional stress and somatic diseases in veterans of special risk units].

Participants of nuclear-powered submarine accident liquidation and special risk units' veterans participating in surface nuclear weapon tests as well as in liquidation of their consequences have been examined. It has been established that functional state of this category of people is difficult to interpret only in the context of radioactive irradiation effect or injuring stress factor exposure. This state is determined by a complex of psychotraumatic factors tending to become aggravated and characterizing by their individual significance and absolute or relative insolvability. In most representatives of this category the disease is manifested by psychopathologic syndrome of neurotic disorders (low spirits, emotional lability, asthenia, anxiety) and somatic disturbances as dysfunction of the cardiovascular, respiratory, digestive and other systems. The results obtained provide the pathogenetic substantiation of efficient ways and methods for rehabilitation of the special risk units' veterans. The data prove the necessity of appropriate correction of cardiovascular disorders in practically healthy servicemen residing under conditions of psychoemotional tension.

[Immunopathogenesis of viral hepatitis C. Immunological markers of the disease progression].

Results of studies of immune response during hepatitis C virus (HCV) infection were reviewed in order to reveal immunologic markers of the disease progression. Genetic heterogeneity of HCV and immunogenetic features of the host determine heterogeneity of immune response to the virus and differences in the course of the disease and outcomes. Spontaneous elimination of HCV-infection in acute phase occurs due to vigorous and sustained multispecific Th1-response toviral antigens. During such response proliferation of virus-specific CD4+ T-cells and secretion of IFN-gamma by them are observed, otherwise chronic hepatitis develops. Great importance in persistence of HCV as well as in quantitative and functional suppression of HCV-specific CD8+ T-cells has increased number of CD4+ CD25+ regulatory T-cells. Cellular immune response plays a key role not only in the elimination of HCV, but also in liver pathology associated with HCV-infection. Progression of the process and shift to its chronic form are also associated with decrease of production of IFN-gamma, alpha, IL-2 by peripheral blood mononuclear cells and increase of TNF-alpha, IFN-gamma, IL-4, IL-2r levels in blood serum.
