[Possibilities of the evaluation of autonomic regulation of cardiac activity in patients with ischemic heart disease using non-invasive methods of examination].

Vegetative control of the heart was assessed on the basis of cardiac rhythm (CR) and stroke volume parameters in the course of an active orthostatic test and bicycle ergometry in 508 myocardial infarction patients and 30 normal subjects. Central hemodynamic parameters and CR spectrum were examined with respect to phases of sleep in 125 coronary patients and 25 normal subjects. Coronary patients showed a disrupted vegetative CR regulation, which was chiefly parasympathetic (reduced CR response to an active orthostatic position and rationed exercise, and a smaller share of high-frequency constituent of the CR energy spectrum).

[Method of quantitative evaluation of functional status and its dynamics among patients with ischemic heart disease during treatment at the Palanga health resort].

The evaluation of functional status of coronary patients has been made by means of a computerized numerical scoring system, using the results of clinical examination, functional cardiovascular and cerebrovascular tests, and psychosocial tests. The effectiveness of rehabilitation and secondary preventive programs for coronary patients treated at a health resort are rated on the basis of a difference between their functional status at the starting and finishing points of the program, as well as the resulting functional status after the program is over.
