After the veterinarian performs a thorough history and physical exam, he or she will listen to the heart and lungs with a stethoscope. Next, the cat's heart rate will be assessed, and certain blood tests may be given to determine the presence of any underlying diseases or medical conditions.
Chest x-rays will reveal changes in the heart size and abnormalities such as fluid in the lungs, which would result from heart failure. The best way for the veterinarian to evaluate the type of heart disease present is by performing an ultrasound of the heart. This test is optimal because it is noninvasive and can distinguish between the different types of heart disease. A heart ultrasound, clinically known as an echocardiogram, can be performed by a veterinary cardiologist, veterinary radiologist, or others with special training in conducting this procedure.
