Abstract
A study on influence of right and left lateral recumbency on Vertebral Heart Score
(VHS) in Pug breed of dogs (12) presented to Veterinary College Hospital, Hassan was
carried out in a period of one year. In this study, the overall occurrence of cardiac diseases
was 1.28% in dogs, irrespective of breeds. The occurrence of cardiac disease in Pug breed
of dogs was 16.98%, highest in age group of 2-6 years (68.68%) and in female dogs
(66.66%). The VHS in healthy Pug breed of dogs (Group A) was 10.28 + 0.20v and 10.08
+ 0.19v in right and left lateral recumbency, respectively. VHS in Pug breed of dogs with
cardiac diseases (Group B) was 11.63 + 0.24v and 11.41 + 0.21v in right and left lateral
recumbency, respectively which was significantly greater than VHS of Group A. The VHS
was subjectively correlated with the findings of thoracic radiography, electrocardiography
and echocardiography. The right lateral VHS was significantly greater than left lateral VHS
in both the groups. There was statistically non-significant variation in physiological
parameter (temperature, except heart rate and respiratory rate), clinical parameter (BCS),
haematological parameters (TEC, Hb, PCV, TLC and DLC) and biochemical parameters
(serum creatinine, ALT and BUN) within and between the groups. VHS is the easily
applicable, interpretable, non-invasive and accurate method for diagnosing cardiac
disorders in dogs using thoracic radiographs. The VHS provided radiographic cardiac
silhouette incorporating all chambers. The electrocardiography provided the electrical
activities of the heart and echocardiography provided myocardial function and intracardiac
morphology. Therefore, the combination of all these techniques will aid in
assessing the severity and significance of known heart disease and helps to evaluate the
therapeutic efficiency.
