Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy is the most commonly seen cardiovascular disease in cats.  In cats suffering from HCM, the walls of the heart become progressively thicker and thicker. The thickening interferes with the ability of the heart to pump blood.  For now, the cause remains unknown.  Please read this article for clinical signs.  HCM Defined, written by by Arnold Plotnick MS, DVM, ACVIM, ABVP

HCM Scanning (Echocardiography Screening)

A single normal echocardiogram does not guarantee a cat is free of disease. Therefore Sphynx should be screened on a routine basis.

Sphynx cats currently in or retired from breeding programs should have annual echocardiograms.  Non breeding Sphynx should be scanned every 12 – 18 months to catch the thickening of the heart while there is time to treat the disease. Echocardiographic screening and the reporting of results and pedigrees to the Sphynx HCM Databases will also help reduce the incidence of HCM within the Sphynx breed if enough breeders and pet owners are involved.
