Abstract

Introduction. The increase in the incidence of cardiovascular pathology (CP) on the background of the increasing extremity of environmental factors observed in recent years requires careful analysis of the relationship between the population’s appealability of this pathology for medical assistance and factors of terrestrial and space weather in various climatic and geographical conditions.

Material and methods. A retrospective analysis of the frequency of ambulance calls (AC) to CP patients, living in the foothill areas, relative to concomitant meteo- and geliogeomagnetic factors was carried out.

Results. There are gender-specific, as well as seasonally specific correlations between the nosologies studied (transitory ischemic attacks (TIA), Ischemic Cardiac Disease (ICD) due to angina) and investigated factors. Significant fluctuations of these factors, their sharp inter-day fluctuations, and interaction effects contribute to an increase in the frequency of calls to the ambulance. In the dynamics of the frequency of calls, the presence of the seasonal component is traced with an emphasis on the winter period, when a spastic type of weather is formed against the background of a decrease in the average daily temperature and an increase in the atmospheric pressure, which has a negative effect on the cardiovascular system, increases risk of cardiovascular accidents. Patients with TIA have high values of systolic BP, Diastolic BP, Pulsed BP, mean BP. Against the background of “acute” meteorological conditions (IWP > 25), Diastolic BP increases, even more, the systolic and cardiac output is significantly reduced. In ICD patients, suffering from angina attacks, the maximum number of ambulance calls is recorded during the winter period due to the negative impact of both the temperature factor and the entire complex of meteorological factors in general. Attacks occurrence in the summer is minimal. 

Conclusion. The data obtained allows predicting the adverse effects of the terrestrial and space weather impact on the human cardiovascular system and taking preventive measures in a timely manner.
