Echocardiographic measurements in the Irish wolfhound: reference values for the breed

Abstract

Out of 400 Irish wolfhounds cardiologically examined, echocardiographic measurements of 262 normal dogs were analyzed to obtain reference values for the breed. Based on regression analysis, several echocardiographic parameters showed significant linear correlation with body weight and with age, but coefficients of determination were low. Therefore, due to a high individual variability of echocardiographic measurements in adult Irish wolfhounds, the predictive value of body weight for echocardiographic measurements was clinically not relevant. Sex had no influence on echocardiographic values. For the estimation of myocardial function, end-systolic volume index (ESVI) (mean, 29.0 ml/m2 +/- standard deviation [SD], 5.9 ml/m2) was determined for the group of 262 normal dogs.
