Cardiovascular disease in rabbit with hypothyroidism
Correlation between the decreased T4 concentration and reduced fractional shortening
The effects of T4 are mainly manifested by positive ino- and chronotropism. The syndrome accompanying hypothyroidism in rabbits (impaired myocardial contractility and reduced ejection capacity) is caused by a deficiency of thyroid hormones - especially T4. This study aims to determine the frequency of reduced fractional shortening in rabbits with hypothyroidism
The study group consisted of a total of 41 animals: 15 males and 26 females, ranging in age from 2 months to 8 years, with echocardiogram showing reduced fractional shortening (<30%), with normal results of heamatological and biochemical tests. Blood was collected in order to measure T4 level. Echocardiographic examinations ...
