INFLUENCE OF LOCAL CRUSTAL HETEROGENEITY ON THE RESIDENTS’ MORBIDITY OF THE NORTHERN URBANIZED TERRITORIES

Abstract

The aim: to reveal the influence of local crustal heterogeneity peculiarities on the course of visceral diseases in the conditions of the northern urbanized territory in the context of Surgut city. Methods. Frequency of patients' medical aid appealability depending on their residence - upper local crustal heterogeneity or upper solid was studied. Besides, comparative average monthly frequency of patients' appealability with acute coronary syndrome and acute cerebrovascular accident, residents of upper local crustal heterogeneity or upper solid was also studied. Medical records of 6 932 patients were analyzed (cardiovascular diseases included). Results. A significant predominance of frequency of appealability among patients with cerebrovascular accident (in 1,5 times), angor pectoris (in 1,4 times), myocardial infarction (in 1,4 times), hypertensive disease attack (in 1,3 times) (p < 0,001), living in the zones of local crustal heterogeneity in comparison with those living upper solid was revealed. Frequency of patients' appealability with acute coronary syndrome and acute cerebrovascular accident living upper local crustal heterogeneity prevails in the periods of geomagnetic activity increase (p < 0,05 and p < 0,01 respectively). Conclusions. Negative effect of geomagnetic field of the Earth's fault zones on cardiovascular system morbidity of the population was revealed. The results of the carried out medico-ecological study open a prospect for a more enhanced study of the ecologically dependent public health from a new perspective of the organism's interaction with geophysical factors.
