[Effect of interplanetary and geomagnetic disturbances on the increase in number of clinically serious medical pathologies (myocardial infarct and stroke)].
We determined with high accuracy the effect in intense geomagnetic storms on myocardial infarction an brain-stroke pathologies. We analysed the large set of data collected in Moscow from 1979 to 1981, we cleaned up the data by the first harmonic of the annual variation, and by the first three harmonics of the 7-day variations (7.0; 3.5; 2.3 days). We found that geomagnetic storms, producing large decreases in the cosmic ray intensity, increase the infarction rate by a factor 1.13 with a statistical confidence of 9 sigma and the brain stroke rate by a factor 1.07 with a statistical confidence of 4.5 sigma.
