[The immune system in coronary atherosclerosis]

A considerable imbalance in humoral and cellular factors of immunity characterized by high B-cell activity associated with a relative T-cell deficiency has been revealed in patients with coronary heart disease. Immunological imbalance is characteristic for all the clinically pronounced forms of coronary heart disease, forming long before obvious lesions of the coronary arteries. This makes it possible to regard patients without coronarographically documented atherosclerosis as having functional form of the process pathogenetically identical to atherosclerosis according to immunological criteria.
