Achieving and maintaining a similar level of development, due to changes in the usual (from a physiological point of view) way of life, and therefore, development and enormous spread of diseases, especially cardiovascular system. Heart as the main circulating pump body primarily suffering from such naplevateltion attitude. Such common problems as coronary artery disease and Clinical - myocardial infarction, - is the cause of the greatest number of deaths in the world.
