[Effect of natural factors on the occurrence of cardiovascular diseases].
The effect of natural environmental factors (indexes of solar activity, geomagnetic disturbances, as well as meteorologic parameters: air temperature and humidity, and atmospheric pressure) on the occurrence of cardiovascular diseases in Ukraine as a whole and in Kiev was analyzed. It is shown that, contrary to the stereotype, the yearly dynamics of cardiovascular diseases in 1980-1990 is in opposite phase with the solar activity cycle. Similar results were obtained for the monthly dynamics of cardiovascular diseases in the period from June 1991 to June 1993. The relative influence of five environmental factors (in complex) on the daily dynamics of cardiovascular diseases for the same period was calculated. The role of heliogeophysical factors becomes especially evident if the daily level of cardiovascular diseases within some month of the year is considered. This result may be interesting for medicinal practice and forecasting of cardiovascular diseases.
