Cardiomyopathy is the disease of the heart muscle. There are a few different types of cardiomyopathy; restrictive, unclassified, hypertrophic, and dilated. Some symptoms in cats include loss of appetite, lethargy, difficulty breathing/panting, and abnormal heart sounds to name a few. If your cat is experiencing one or more of these symptoms you should have your veteruinarian evaluate them. Cardiomyopathy is diagnosed by doing an electrocardiogram to examine the electrical currents in the heart muscles and by doing radiographs and echocardiographs to use images of the heart to visually identify heart enlargment or thickened walls. There can be many causes of cardiomyopathy so it is important to fully assess your pets health from head to toes using multiple diagnostic tools.
