다국어 초록 (Multilingual Abstract)

A l0-month-old, neutered male, British shorthair cat was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of tachypnea, anorexia and depression which onset were two days ago. On physical examination, increased respiratory rate and no murmur were found. A complete blood count indicated thrombocytosis. Results from a serum biochemical profile demonstrated elevations in CK, ALP, BUN and Ca, and decreases in sodium, potassium and chloride. Thoracic radiographs revealed patchy interstitial opacity increase and left atrium enlargement. Echocardiographs showed the evidences of hypertrophic cardiomyopathy which were hypertrophy of diastolic interventricular septum and left ventricular free wall. Other findings on echocardiography were the reverse E:A ratio(tranmitra1 inflow pattern) and absence of systolic anterior motion of mitral valve. Electrocardiographs demonstrated wide P and R wave, which mean left atrium enlargement and left bundle branch block, respectively. Medications including furosemide (2mg/kg), enalapril (0.25mg/kg), and spironolactone (1mg/kg) were prescribed twice a day and orally. Client education about exercise restriction and possibility of aggressive progress was given. Clinical signs suggestive of thromboembolism were developed on 6th day after showing tachypnea; right forelimb lameness, bilateral hindlimb lameness, loss of femoral pulse and severe pain. After all, euthanasia was performed at local animal hospital, according to the owner's request.
