Influence of heliogeophysical factors on patients with myocardial infarction

Introduction: Global climate change is already affecting the health, living conditions, and livelihoods of people on all continents. According to many researchers, the deterioration of the patient's condition is manifested after a solar flare, with the onset of a magnetic storm. Aim: The aim of the article is to study the influence of heliogeophysical factors on the development and outcomes of myocardial infarction. Material and methods: Using data on the effect of space weather on a person from France, Germany, China, Israel, Lithuania, Georgia, a number of Russian clinics – wherever patients with ischemic heart disease were observed, during magnetic storms. Results and discussion: An in-depth study of mortality from myocardial infarction in various climatic and geographical regions showed the dependence of the number of deaths on the season of the year and sharp fluctuations in individual meteorological parameters of the weather to a much greater extent in the year of solar activity. Conclusions: It was found that patients with cardiovascular diseases (CVD) are especially susceptible to heliogeophysical disturbances. The number and severity of CVD depend on many environmental factors (atmospheric pressure, air temperature, cloud amount, ionisation, radiation regime, etc.), a reliable and stable relationship of CVD is revealed with chromospheric flares and geomagnetic storms.

STUDY OF THE RELATIONSHIP BETWEEN HELIOGEOPHYSICAL FACTORS AND THE COURSE OF CERTAIN PHYSIOLOGICAL PROCESSES IN INDIVIDUALS WITH DIFFERENT PSYCHOSOMATIC STATUS AS A COMPONENT OF PSYCHOLOGICAL SUPPORT

Тhe purpose of the study: to establish a correlation between the average annual values of the minute volume of blood flow in hypertensive men with different temperaments and high anxiety and solar activity. There were 848 patients with arterial hypertension and 422 healthy individuals. All of them were determined by temperament and anxiety, and the minute volume of blood flow. To compare the calculated method for determining the minute volume of blood flow with the hardware method, the authors measured the minute volume of blood flow in patients using tetrapolar rheography on a 6-NEG device connected with a computer and compared it with the value of the minute volume of blood flow determined by calculation. Data on the dynamics of solar activity in wolf numbers and radio emission at a wavelength of 10.5 cm were obtained from the West-Siberian Department for Hydrometeorology and Environmental Monitoring. During the period of increased solar activity, the body was affected by a complex of factors, including socio-economic factors, together with ionizing radiation of the environment; contribute to a decrease in the coefficient of oxygen utilization by tissues, which caused the development of an adaptive reaction, part of which was an increase in the minute volume of blood flow. A significant correlation was established between solar activity indicators, meteorological factors, and minute blood flow volume, which indicates the possibility of a combined effect of the studied factors on increasing the functional activity of the cardiovascular system.

Correlation between heliogeophysical factors and osmotic pressure of blood plasma in patients with arterial hypertension with different temperament

The relation between heliogeophysical factors and the osmotic pressure of blood plasma in patients with arterial hypertension with different temperaments is analyzed. It is found that with increasing solar activity (Wolf numbers and radio flux wavelength 10,7 cm), is closely related increase in atmospheric pressure, air temperature and γ-background (within normal limits) in the workplace examinees. It was revealed that in choleric and sanguine patients there is a reliable high inverse correlation relationship between heliogeophysical, meteorological factors and total peripheral vascular resistance, while the phlegmatic and melancholic - the average direct and direct high correlation relationship. Antihypertensive therapy with diuretics with increased solar activity, combined with an increase in the atmospheric pressure, γ-background and the air temperature in the workplace, due a decrease in total peripheral vascular resistance at the choleric and sanguine and increase in total peripheral vascular resistance in healthy individuals and phlegmatic patients and melancholic. The presence of significant and reverse correlation relationship between the total peripheral vascular resistance and osmotic pressure of blood plasma in choleric and sanguine and significant, but a direct correlation - the phlegmatic and melancholic indicates the inclusion of an adaptive process various physiological mechanisms, which determines the need to consider the temperament at solar biospheric relations bonds.

Impact of heliogeophysical factors on the clinical-biochemical indices in pregnant women

<p>The influence of heliogeophysical factors on the clinical and biochemical parameters of pregnant women with easy and complicated births was studied. The influence of the events of the current day and the previous solar and geomagnetic activity on clinical and biochemical parameters of pregnant women with normal and complicated births was revealed. 164 pregnant women aged from 17 to 44 years, living in Barnaul, Altai region, were examined. According to the type of delivery two groups of women were identified:1) women with easy birth (46 people), 2) women with complicated birth (118 people). The following indicators were used to estimate the level of solar and geomagnetic activity: the number of sunspots, the number of Wolff, radiation at a wavelength of 10.7 cm, the average daily magnetic field perturbation (A_p– index), and the local geomagnetic disturbance index (A_k– index). Pregnant women were examined using the following parameters: the number of erythrocytes, leukocytes, blood platelets, leukocyte count, clotting time, erythrocyte sedimentation rate, prothrombin index, hemoglobin, sugar, fibrinogen, bilirubin (direct, indirect and total), total blood protein, and specific gravity. It has been established that the influence of heliogeophysical factors consists of immediate and delayed reactions with different latent periods: among women with normal births the most significant events are the events of the current day, as well as the 3rd, 6th and 7th days before the examination; among women with difficult births - on the 2nd, 4th, 5th and 7th days. Among heliogeophysical factors the average daily disturbance of the Earth's magnetic field has the greatest influence on clinical and biochemical parameters. 60% of the clinical and biochemical parameters analyzed among pregnant women depend on this factor. Clinical and biochemical indicators are less susceptible to heliogeophysical factors among women with complicated births. The coefficient of determination by the factors of solar activity reaches 25% (direct bilirubin) among them; factors of geomagnetic activity - 31.5% (urine protein), whereas in the group of women with normal births the coefficient of determination is 50% (total bilirubin) and 71% (total bilirubin). According to clinical-biochemical indicators 8 types of correlations were found: 1 type – at low level of solar and geomagnetic activity, 4 types – at medium and 3 types at high level. Linear and nonlinear functional dependencies of the indicators on heliogeophysical factors are revealed for each typological group.</p>

Influence of heliogeophysical factors on the minute blood volume in hypertensive patients with different temperament

Correlation between the annual average values of minute volume of blood flow in healthy men with different psychosomatic status, suffering from arterial hypertension, and Solar activity from 1995 to 2015 was investigated. Variations of γ-background during the study period did not exceed the limits of normal regional values (7-9 µr/h). However, the analysis of solar activity dynamics represented periodic increase and a momentary increase by the 2005-2006. With the increase in solar activity and γ-ray background a significant reduction of oxygen utilization coefficient by tissues of healthy individuals and patients with different temperament was noted. The increase in solar activity was followed by an increase in ambient temperature and atmospheric pressure. The study showed a significant increase in minute volume of blood flow in the groups of healthy individuals and patients in the same years as the increase in solar activity and γ-background environment. There has been established a significant correlation relationship between indicators of solar activity, meteorological factors and minute volume of blood flow that indicates on the possibility of combined effects of the studied environmental factors to affect the course of physiological processes in organism of both healthy and hypertension person. Overall, it was reflected in the increase of functional activity of the cardiovascular system (by minute volume of blood flow).

Evaluation of significance of melatonin and some atmospheric and heliogeophysical factors for patients with acute coronary syndrome

Introduction. Changes in melatonin (MT) production affected by earth magnetic field (EMF) were documented, including but not limited to patients with cardiovascular diseases. Thus far, the connection between MT content and atmospheric and heliogeophysical factors with regard to acute coronary syndrome (ACS) patients has not been thoroughly studied and the existing data are controversial. Material and methods. The levels of MT metabolite 6-hydroxymelatonin were measured in urine at night (MTn) and day (MTd) time in 114 ACS and 26 stable angina (SA) patients on days 1-3 of hospital stay. Results. Significant inverse correlation between MTn content and EMF H and D-components (H, D) of EMF was found in ACS patients as well as direct correlation between the MTn levels and solar radiation flux density at a wavelength of 10.7 cm (F-10.7) and the number of sun spots (the Wolf number - W). Significant direct correlation was shown between EMF D-component value, Kp- and Ap- geomagnetic activity indices in ACS patients developing cardiovascular complications. For ACS patients, the risk of development of cardiovascular complications was 1,62 and 1,15 times greater at high Kp- and Ap-indices respectively. Conclusion. Direct connection between MTn level and solar activity factors was observed in ACS patients together with inverse correlation with geomagnetic activity which confirms the influence of heliogeophysical factors on MT production. The risk of developing cardiovascular complications increases at higher Kp-and Ap- indices which proves the effect of heliogeophysical factors on the clinical course of cardiovascular pathology. The MTn content was shown to decrease in winter in these patients.
