title: [Changes in the structural characteristics and ATPase activity of the erythrocyte membranes in angiographically verified coronary artery lesion].
abstract: Structural characteristics and Na, K-ATPase activity of erythrocyte membranes were studied by the spin probe method in patients with an angiographically verified damage to the coronary arteries. The rise of the cholesterol/phospholipid ratio in patients with coronary heart disease was associated with the increased orderliness of the fatty acid chains of erythrocyte membrane lipids, leading to inhibition of Na, K-ATPase activity. The data point to the same line of changes in erythrocyte membranes and smooth muscle cells during the development of coronary heart disease.
