[Anaerobic threshold in patients with chronic circulatory insufficiency].

To evaluate the severity of chronic circulatory insufficiency (CCI), 12 healthy subjects and 69 patients with cardiovascular diseases underwent exercise testing. Parameters such as anaerobic threshold (AT) and peak oxygen consumption (peak VO2) were measured by respiratory gas analysis to assess the circulatory insufficiency. AT decreased with an increase in New York Heart Association functional class and amounted to 18.

[Body water compartments of patients with chronic heart failure and the refractory edema syndrome].

Using modern methods of investigation body water spaces were studied in 44 persons: 12 healthy ones and 32 patients with various degrees of heart failure. Significant changes in the content and distribution of water with regard to a degree of decompensation were revealed. Dilatation of the volume of extracellular fluid (VEF) was observed in patients with noticeable peripheral edemas as a result of an increase in the volume of circulating plasma (VCP) and an increase in the volume of interstitial fluid (VIF).

[Clinical and hemodynamic effectiveness of isolated ultrafiltration in the treatment of patients with severe cardiac insufficiency].

A study was made of the clinical and hemodynamic efficacy of a session or a course of isolated ultrafiltration (IUF) and a relationship of changes of the central and peripheral hemodynamics with the activity of the renin-aldosterone system in patients with severe cardiac insufficiency. Two groups of patients were singled out differing in their hemodynamic and hormonal response to the first IUF session that might be due to a different level of adaptation mechanisms acting in the interference in disturbed homeostasis.
