Usefulness of determining some markers of myocardial damage in sports horses subjected to physical exertion

The aim of the study was to evaluate usefulness determining markers myocardial damage, such as: aspartate aminotransferase, total creatine kinase, cardiac kinase isoenzyme, lactate dehydrogenase, dehydrogenase isoenzyme and peripheral blood lactic acid in sport horses subjected physical exertion. research carried out on 50 three breeds: Ukrainian Riding, Hanoverian Westphalian, aged 4-16 years. In all horses, activity of: concentration were marked before after exercise. It found that exercise tested there an increase damage. On basis conducted research, it demonstrated highest concerned kinase. studies additionally indicate evaluation damage may be useful as a screening test detecting muscle disorders associated with excessive However, should emphasized must considered together results clinical examination additional tests ultrasound electrocardiography.
