[Use of indicators of anaerobic metabolism in the evaluation of the functional reserve of the cardiovascular system in patients operated on in the past for congenital heart defects].

The correlation of most important parameters of the central hemodynamics with the intensity of anaerobic metabolism was studied in 65 patients operated on having congenital heart diseases and in 37 healthy patients under increased physical exercise. A mild decrease of the functional reserve of the cardiovascular system (by 7-15%) was revealed in the patients as compared with the control group.
