Modern Approach to Arterial Hypertension in the Circumpolar and Arctic Regions. Literature Review

A new approach to the problem of significant youthification of arterial hypertension and its fast progression in non-indigenous populations of the polar and arctic regions has been presented. The hypertension progression in high latitudes is combined with influence of climate change biological stressful pace in the Arctic area and influence of adverse space, geophysical, weather, chronobiologi-cal factors. Research scientists of the Russian polar and arctic regions have identified a number of leading elements of the northern climatic-geographic chronic stress which make the main contribution to formation and progression of hypertension in the North. The most characteristic manifestations of climatic-geographic stress in uncomfortable and extreme regions of the North and Siberia are reactions of the central nervous and endocrine systems, metabolic changes and development of "oxidative stress". In addition to these manifestations the polisindromatic climatic stress may include: deficit of detoxification processes and barrier organs, northern metabolic type disorders, northern tissue hypoxia, immune deficiency, blood hypercoagulation, multiple endocrine disorders, regenerative and plastic failure, violation of electromagnetic homeostasis, functional dissymmetry of interhemispheric relations, desynchronosis, emotional stress, meteopathies. Obviously, creation of advanced innovative preventive and therapeutic technologies to reduce spread of hypertension among population in the polar and arctic regions require active study of the northern stress mechanisms' role in progression of this severe cardiovascular pathology.
