Abstract

The purpose of the research was to study the age features of rheological and hemostatic blood properties dependence on the influence of cosmic and heliogeophysical factors (solar, geomanetic activity, high-energy particle fluxes of solar and cosmic origin) in 220 patients with hypertension, aged 30-69 years. The analysis included the following hemostatic and hemorheological parameters: clotting time, duration of bleeding, prothrombin index, ADP-induced platelet aggregation, blood viscosity. The study was conducted under background conditions and under conditions of the modeled weakening of the geomagnetic field. When analyzing the influence of heliogeophysical factors on hemostatic and rheological parameters in the background conditions the greatest number of significant correlations, indicating to the increased blood clotting at the increase in solar activity, as well as to the association of hemostatic processes with the intensity of solar protons and electrons was observed in the age groups 50-59 years and 60-69 years. The most pronounced reaction with a decrease in blood viscosity and weakening of its dependence on the solar activity at short-term incubation of blood samples in hypo geomagnetic installation were identified in the older age group (60-69 years). In general, strengthening of rheological and hemostatic blood properties dependence on heliogeophysical factors with increasing age was revealed. The role of changing human sensitivity to solar and geomagnetic activity in the conditions of the annual weakening of the magnetic field in the process of premature aging is under discussion.
