Changes in lipid metabolism in cardiac failure in patients with rheumatic heart disease

Aim. The study of lipid metabolism parameters involved in lipid mechanisms of damage and elucidation of their role in disorders of central hemodynamics (CH), microcirculation (MC) and oxygenation (OC) of peripheral tissues in cardiac failure (CF) in rheumatic patients. Materials and methods. In 55 patients with rheumatic heart disease (RHD) with CF measurements were made of serum characteristics of peroxidation-antioxidant balance, activity of phospholipase A2, concentration of nonesterifized fatty acids, total lipids, total phospholipids, total, ether-bound and free cholesterol, skin OC and MC. Tetrapolar chest rheography was followed by calculation CH parameters. Results. CF aggravation occurred in parallel with progression of generalized activation of lipid peroxidation (LPO) and phospholipase A2. LPO activation contributes to inhibition of antioxidant activity and to decline of hypercholetsrolemia. Negative correlation exists between primary LPO products, dienic conjugates and CH. Conclusion. LPO and phospholipase A2 activation are essential in the onset and progression of CF in RHD patients. This should be considered in therapy of such patients.
