[Indicators of spiroveloergometry and the sympathetic-adrenal system in patients with exertion-induced angina pectoris with different types of circulation].
The response of the cardiorespiratory and sympathoadrenal (SA) systems to exercise in coronary heart disease patients was found to depend on the hemodynamic type of circulation and the initial activity of the SA system. In patients with the hyperkinetic type of the circulation showing a high initial activity of the SA system and the absence of its response to exercise, the authors observed an increased consumption of oxygen both at rest and during mild exercise which indicated that oxygen expenditure in these patients was ineffective, and subsequently led to a reduction in their capacity to do physical work. Patients with the hypokinetic circulation type and an initially low activity of the SA system exhibited a considerable elevation in the activity of the hormonal component of the SA system during exercise. The maximum oxygen consumption during exercise in these patients was significantly lower than in patients with other types of the blood circulation.
