Abstract
The present study was conducted to study the prevalence of cardiac ailments and to compare
echocardiographic parameters with the control healthy animal in an endeavour to establish standardized
echocardiographic parameters for dogs vis-à-vis correlate with the body weight to diagnose the cardiac
ailment like DCM and HCM with affluence.The present study was conducted on 30 clinical cases (22 Male,8 Female)
belonging to various canine breeds (more Labrador breed of dogs) which encompassed 12 (40%) clinically
healthy control dogs and 18 (60%) dogs with cardiac ailments. The patients were subjected to meticulous
physical, clinic-physiological, radiographic and electrocardiographic examinations before categorising
them to different groups like healthy control group and experimental group, respectively. Experimental
group was further subdivided into DCM and HCM groups based upon echocardiographic findings [DCM-
14 (77.78%) and HCM-4 (22.22%)]. All the patients under the study were subjected to two-dimensional Bmode,
M-mode and Doppler echocardiographic examinations. Mean values of various echocardiographic
parameters were compared statistically across all groups. Echocardiographic parameters from healthy
control groups were correlated with body weight and to establish a regression equation to standardise
different echocardiographic parameters.Prevalence was more among male Labrador with age more than 5 years of age. A significant
difference (P 0.5) linear correlations of echocardiographic parameters against bodyweight was
detected for LVIDs, LVIDd, Ao, LVEdA4C, LVEsA4C, LMV, EDV and ESV. Whereas, statistically
significant (P 0.5) linear correlations was observed between
echocardiographic parameters and body weight (BW) for LVIDs, LVIDd, Ao, LVEdA4C, LVEsA4C,
LMV, EDV and ESV. Whereas, statistically significant (P < 0.05) negative linear strong correlations
among body weight (BW) and echocardiographic parameters was observed for RI only
