Viable Myocardium: Blood Antioxidative Defense and Content of the Erythrocyte Intracellular Calcium

摘要

It was studied possibility of using of noninvasive stress-test of echocardiography (echo-CG) and electrocardiotopography (EGG-mapping (60 leads)) with dobutamin, and also biochemical and biophysical parameters for diagnostics of hibernating and stunned myocardium at patients with ischemic heart disease (IHD) with a various degree it dysfunction. It was shown, that the stress-tests - echo-CG and EGG-mapping (60 leads) with dobutamin probe have high sensitivity and specificity in diagnostics of convertible myocardium dysfunction left ventricular at the patients with IHD. The data about physic-chemical state of erythrocytes (ratio of the activities superoxide dismutase and glutationperoxidase, content of the erythrocyte intracellular calcium of membranes erylhrocytcs) can be useful for an estimation of a degree oxidative stress in red blood cells at the patients with IHD under hibernation and stunning.
