210 patients with ischemic heart disease and heart failure, stage I, HA, IIB, aged 60 to 74 years, have been examined. The effect of HBO on central hemodynamics, gas composition and acid-base balance has been assessed. It has been established that HBO is associated with a definite tendency towards cardiac output normalization, as well as hemodynamic economization associated with accelerated heart rate and more adequate correlation between cardiac output and peripheral vascular resistance. The analysis of gas exchange and acid-base balance parameters indicates HBO-induced acidotic shifts. The data of polarographic studies demonstrate that increased metabolic activity is typical not only of the cardiac muscle but of other tissues as well. A favourable effect of HBO on oxygen tissue supply in patients with ischemic heart disease and heart failure is to a certain extent due to stimulation of peripheral circulation and its capillary compartment.
