Feline cardiomyopathies are of several kinds.
Dilated and Hypertrophic Cardiomyopathies are the most common. In addition to the above specific cardiomyopathies, cats can also develop valvular disorders, some of which are idiopathic in etiology. . The remainder of this discussion will focus on the anatomical and physiological manifestations, the diagnosis and proposed treatment of Feline Hypertrophic Cardiomyopathy. The idiopathic form of HCM may have a heritable basis, possibly aberrant genes encoding for altered sarcomeric proteins. Evidence suggesting this is based upon limited studies in Main Coon, Persian and American Shorthair breeding populations.
