Study of left ventricular sphericity index in healthy and dilated Cardiomyopathy affected dogs

The study was conducted at Teaching Veterinary Clinical Complex Parel, Mumbai Veterinary College, and Bai Sakarbai Dinshaw Petit Hospital. The present research focused on study of Left Ventricular Sphericity Index (LVSI) in two groups of dogs i.e healthy dogs and those affected by Dilated Cardiomyopathy (DCM). Echocardiographic examinations were performed to analyse cardiac geometry changes using the LVSI. The control group comprised dogs without abnormalities, while the DCM group included dogs with DCM symptoms and heart enlargement. Results revealed that the LVSI was significantly lower in DCM-affected dogs (1.29 ± 0.03) compared to healthy dogs (1.95 ± 0.04), indicating ventricular enlargement. Echocardiography confirmed this trend, showing a substantial increase in left ventricular diastolic diameter (LVDd) in the DCM group. This study enriches the understanding of cardiac remodelling, contributing to the diagnosis and management of Dilated Cardiomyopathy in veterinary practice.
