Hypertrophic Cardiomyopathy (HCM) in Cats

Did you know that Hypertrophic Cardiomyopathy (HCM) is the number one form of heart disease in cats? HCM can affect all breeds, but is commonly seen in the Cornish Rex, Maine Coon, and Ragdoll breeds. HCM causes a thickening of the heart muscle making the main pump become small in size and creating less room for blood flow. The disease can cause abnormal dilation of the left atrium and abnormal blood flow in the heart. As a result the cat can develop congestive heart failure, irregular heartbeat, blood clots and even sudden death. HCM is often referred to as the ‘occult’ silent killer in cats because of its ability to go undetected and kill suddenly. Screenings are available to determine the presence of HCM in cats that are to be bred. Screening is also available for cats that have heart murmurs or other heart related illnesses. For more information, consult with your Rochester, NY veterinarian.
