DIAGNOSIS IN HYPERTROPHIC CARDIOMYOPATHY
DOMESTIC CAT: CLINICAL RESEARCH

V. N. Plysiuk, M. I. Tsvilikhovski

Abstract.To date, the diagnosis of diseases of small animals meet high demands. Pet symptoms received on physical examination methods are not reliable confirmation of any form of cardiomyopathy in a domestic cat. Recently, more and more doctors recognize that the probability of detecting hypertrophic cardiomyopathy during physical examination is extremely low. Confirmation of the diagnosis of hypertrophic cardiomyopathy forms require additional diagnostic methods. Application of new methods of examination such as ultrasound, and use the known methods of research animals - radiography and electrocardiography, enable authentic assessment malfunction of the heart and abnormalities in its anatomy.

The aim of this work was to study the phenotypic manifestations of hyper-trophic cardiomyopathy in the domestic cat using instrumental methods of research.

Radiography and electrocardiography data make it possible to fix the pathological changes that are the result of hypertrophic cardiomyopathy. But these data do not allow to verify and classify the existing type of cardiomyopathy.

Echocardiography is currently the only non-invasive method of clinical examination of animals with cardiomyopathy, which allows you to determine abnormalities in the anatomy of the heart, to confirm the diagnosis and classify the type of cardiomyopathy.

Because of myocardial hypertrophy in patients with cats reduced left ventricular cavity. As a result of this reduced stroke and minute volume of blood, which leads to body tissue hypoxia. Compensatory mechanisms at the same time becoming increasing myocardial contractility (myocardial hyperkinesis development) and heart rate (tachyarrhythmia development).
