Аннотация:In this work the relationship between emergency medical calls for myocardial infarction in
Yakutsk (subauroral geomagnetic latitudes) and parameters of the space weather near maximum (1992) and minimum (1998) geomagnetic activity is studied. The comparison of the seasonal behavior of the number of calls with the simultaneous seasonal behavior of deaths from myocardial infarctions at low latitudes (Bulgaria) exhibited significant differences. Namely, in Bulgaria, the maximum and minimum of infarctions were observed in winter and in summer, respectively; in Yakutsk, several observed maximums coincided with the sharp and considerable increase in planetary geomagnetic activity. An analysis of experimental results made it possible to suppose that, in subauroral latitudes, unlike low latitudes, a major role in the increase in the number of infarctions is played by the increase in geomagnetic activity, namely, by the appearance of night magnetospheric substorms, which are also observed in subauroral latitudes in magnetically disturbed times. Substorms are always accompanied by irregular geomagnetic Pi1 pulsations with periods of 0.5–3 Hz. These pulsations can be biotropic, like stable quasi-sinusoidal geomagnetic Pc1 pulsations in middle and low latitudes.
