Hypertrophic Cardiomyopathy

What is Hypertrophic Cardiomyopathy (HCM)?


HCM is the thickening of the left ventricle wall and overall enlargement that can lead to heart failure. It is a common disease that can develop in both purebred and mixed cats. While most cases of HCM are hereditary, there are instances where it can occur for absolutely no reason. This is why HCM screening is so important, especially from reputable breeders. 


There is not a specific test that exists for HCM, however, the heart can be screened, measured, and monitored using an echocardiogram from a veterinary cardiologist. The screening is used as a precautionary measure but does not guarantee that HCM will not occur. 


Bengal-data.com is a database that many breeders have used to contribute HCM data from the genetics of their cats for the public to track.
