The study aimed to identify the initial signs of immune violations at professional athletes with the mitral valve prolapse. Material and methods. For establishment of frequency of occurrence of the mitral valve prolapse as manifestations of a displaziya of connecting fibers among professional athletes 541 persons were surveyed (329 young men and 212 girls), an average age was 22,4±1,2 and 21,3±1,3 years respectively. The athletes were exposed to the echocardiography doppler in a prone position on the left side. The immune status of athletes estimated indicators of cellular and humoral immunity: quantity of leukocytes, lymphocytes, phagocyte activity of leukocytes, T indicators — and V-cellular immunity. Phagocyte activity of leukocytes (monocytes and neutrophils) blood was estimated on an indicator of a phagocyte index — number of leukocytes (at %), capable to phagocyte a test-microbe (epidermal staphylococcus). Results. The mitral valve prolapse was revealed at 132 people (24,4%), 74 young men (22,5%) and 58 girls (27,4%). At athletes with a prolapse (132 people) had changes in the immune system, being shown in decrease of levels of im-munoglobulins, total of leukocytes in comparison with athletes without prolapse are revealed. Conclusions. At athletes with the mitral valve prolapse (especially at girls) in the course of adaptation to long and considerable physical activities changes are more often shown from immune system, than athletes without heart pathology. In particular, the total of leukocytes, level of immunoglobulins A and M decreases.
