Background. The goal of the paper is to study the influence of solar flare activity and geomagnetic storms on the cyclicity of cerebral and coronary vascular catastrophes.
Materials and methods. The authors analyzed medical cards of patients with myocardial infarction (n = 927) and cerebral stroke (n = 942). The dynamics of the Wolf numbers and Aр-index was determined. The method of superposed epochs was used with the calculation of the Spearman's rank correlation coefficient.
Results. Intra-annual dynamics of cerebral and coronary vascular catastrophes morbidity is uneven, has a nonlinear, oscillatory, cyclic character. It reliably correlates with the dynamics of solar flare activity and geomagnetic activity. The morbidity of myocardial infarction is more correlated with geomagnetic activity, while the morbidity of cerebral stroke is with the activity of the Sun. A kind of "delay effect" is found, which is most likely due to the temporary organization of the stress reaction.
Conclusions. The obtained results testify to the influence of solar flare activity and geomagnetic activity on the dynamics of the manifestation of cerebral and coronary vascular catastrophes. The trigger effect of space weather factors is realized through the activation of a stress-realizing system in the diseased organism. To limit the negative effects of solar flares and magnetic storms, a systematic approach is needed.
