[Aspects of acclimatization of the human body to acute and chronic high-altitude hypoxia].
Exposure of human body to high altitude environment initiate reaction which could be result whether of adaptation or of exhaustion. The purpose is to establish the human body environment which enables regeneration of own cells. Therefore, mechanism of reestablishment of prevention and recognition of symptoms and signs of insufficient adaptability on high altitude are of great interest for clinical and other medical investigators. Special position in research refers on cardiovascular system. Results show, according to effect of only one factor-catecholamines, that in course of physical training on high altitude, could be expected, cardiac muscle hypertrophy. It is proved, that under special circumstances catecholamines stimulate synthesis of proteins what enables faster regeneration of the cells. However, under conditions of myocardial ischemia, uncontrolled loading of these patients could lead to deterioration of heart function appearance of cardiac insufficiency.
