Prevalence of Cardiac Disorders in Canines-A Clinical Study

The aimed study was to evaluate the prevalence of cardiac disorders in canines based on clinical presentation, laboratory, electrocardiographic, radiographic, two dimensional echocardiography, M-mode echocardiography and color flow doppler. The overall prevalence of cardiac disorders in dogs was 1.77% and it was 56.21% among dogs exhibiting clinical manifestations suggestive of heart disease. The highest prevalence was recorded in male, Labrador retriever between 510 years of age and lowest in female, Dachshund less than 5 years of age. Exercise intolerance and cough were the significant clinical manifestations. On radiography, cardiomegaly and pulmonary edema were the major findings observed of electrocardiography, elevated R wave was the significant observation. Echocardiography revealed dilated cardiomyopathy, an acquired heart disease as more prevalent cardiac disorder in canines.
