[Parameters of hemodynamics and red cell redox-status in old patients with ischemic heart disease]

Red cell redox-status and hemodynamic changes were studied in 60 old patients with ischemic heart disease. The treatment consisted of standard therapy (ST), ST + amino acid composition (glutaminic acid, glycine, cysteine) or preductal (15, 30 and 15 patients, respectively). Glutathione levels, activity of glutathione-transferase, reductase, peroxidase, catalase, Cu-, Zn-superoxide dismutase, red cell levels of malonic dialdehyde, hemodynamic parameters according to echo-CG and ECG monitoring were estimated before the treatment and 20 days after it. Endogenic antioxidant defense/hemodynamic parameters correlation coefficients were calculated. Close correlations were not found. However, ST + amino acid composition demonstrated the weakest correlations between the antioxidant defense and hemodynamics, while ST + preductal produced the greatest number of correlations. It is suggested that amino acids promote search for the antioxidant system's optimum while ST + preductal promotes closer correlations between red cell redox status and hemodynamic parameters.
