Enzyme Immunoassay of Antibodies to Endogenous Bioregulators for Evaluating the Risk of Heart Disease

Abstract

The levels of natural antibodies to β-endorphin, bradykinin, histamine, dopamine, and serotonin were measured in 271 cardiological patients in order to evaluate the severity of their clinical status. The patients were distributed into groups differing by the course of the pathological process. The levels of natural antibodies to all antigens were maximum in patients with cardiosclerosis: the content of antibodies to β-endorphin surpassed the control by 46%, to histamine by 62%, to bradykinin by 36%, to dopamine by 49%, and to serotonin by 65%.
