Echocardiography and Radiography Study of Left Heart Dilated Cardiomyopathy in Small Breed of Dogs

Dilated cardiomyopathy (DCM) is one of the most common cardiac diseases in dogs. If this disease is not detected and treated in time, it may cause the death of the affected animal. For this reason, its timely diagnosis is very important. This study was also carried out to investigate and identify the echocardiographic and radiographic indicators of dogs with DCM by sex, sterility status, breed, age and weight. For this purpose, using echocardiography and radiography, various parameters of the left ventricle and VHS (Vertebrae Heart Scale) of all dogs with DCM were measured. The results showed that the highest rate of prevalence was related to male dogs, not sterilized, terrier, age group 6-9 years and weight 5-10 kg. The findings of echocardiography showed that between the parameters of IVSs and LVDs in male and female DCM dogs, EF and FS of different sterility status, LVD and RVD of different breeds, all parameters measured in different weights and EF, LVDd and LVDs are a statistically significant difference in different ages. The average VHS of dogs with breed, age, sterility status and different weights with DCM were significantly different from each other. Also, the findings showed that gender has no effect on VHS change. Therefore, knowing the population with DCM disease, and other diagnostic imaging findings related to it, can help in the early diagnosis of this disease. After that, the findings of this research can be considered as a valid reference in the examination of different dogs with DCM.
