[Disorders of nitrogen metabolism in circulatory insufficiency]

The state of nitrogen metabolism was studied on the basis of clinical observations and nitrogen metabolism indices in 102 patients with circulatory insufficiency occurring against the background of rheumatic heart diseases, atherosclerotic cardiosclerosis and chronic corpulmonale. Nitrogen metabolism disorders were found in all stages of circulatory insufficiency. These disorders may be the cause of these patients' resistance to therapy.
