[New data on the mechanisms of adaptation to physical load in ischemic heart disease and their use in rehabilitating myocardial infarct patients].
Oxygen consumption during physical exercise was examined in post-myocardial infarction patients and normal subjects. Similar exercise caused different oxygen consumption in patients of different functional categories. Once the steady state is reached, patients belonging to more favourable functional categories have increased oxygen consumption, as compared to normal subjects, which enables them to cope with fairly great physical stress. In patients belonging to poor functional categories, oxygen consumption decreases during exercise, preventing them from reaching greater levels of physical stress and resulting in "oxygen debt" which only subsides after exercise is over. Therefore, two types of adaptation to physical stress were identified in coronary patients, which is of practical relevance to programs of physical rehabilitation for myocardial infarction survivors.
