Abstract This study aimed to first, determine typical M-mode and 2D echocardiographic measurements in apparently healthy Persian cats as well as their correlation with gender, age and body weight. Second, in apparently healthy Persian cats, asses the normal M-mode and 2D echocardiographic measurements obtained from right lateral recumbence position and comparing them to standing position. Thirdly, evaluate the prevalence of hypertrophic cardiomyopathy in apparently healthy Persian cats. M-mode echocardiography was performed on 78 apparently healthy Persian cats of both genders (24 males and 54 females) ranging in age from 2 to 14 years and weighing (2-5) kg. The measurements were performed from the heart’s right parasternal long axis left ventricular outflow tract perspective. The parameters recorded were: Left ventricular internal dimension, interventricular septal thickness and left ventricular posterior wall thickness during diastole and systole, left atrial diameter, aortic root diameter, left ventricular systolic functional parameters, and indices and mitral valve parameters. When the posterior wall of the left ventricle measured ≥ 6 mm (Silva, A. C., et al 2013) at the end of diastole, it was determined that there was left ventricular hypertrophy. To detect the apparently healthy Persian cats with hypertrophic cardiomyopathy, a separate group was formed for Persian cats whose posterior wall during end of diastole was ≥ 6 mm. Position found to have no influence on echocardiographic measurements where. Gender had statistically significant on heart rate (p=0.002), with females having a higher heart rate than males. Age had effect on left ventricle posterior wall during diastole (LVPWd). Gender, age and body weight had no statistically significance on LVID during diastole and systole, IVS during diastole and systole, LAD and AOD. Posterior wall during diastole was found to be increased by increasing age and posterior wall during systole was also increase by increasing body weight. Hypertrophic cardiomyopathy (HCM) was identified in 12 (15.3%) of the 78 examined cats. Apparently normal cats should be screened for HCM. |
