Sphynx cat instance of cat breed
Hypertrophic cardiomyopathy
The breed does have instances of the genetic disorder hypertrophic cardiomyopathy (HCM). Other domestic cat breeds prone to HCM include Persian, Ragdoll, Norwegian Forest cat, Siberian cats, British Shorthair and Maine Coon; however, any domestic cat including mixed breeds can acquire HCM. Studies are being undertaken to understand the links in breeding and the disorder. Cats are screened for HCM disease with echocardiography (ultrasound of the heart), as well as with additional tests determined by the veterinarian cardiologist including electrocardiogram (EKG, ECG), chest radiographs (X-rays), and/or blood tests.The Sphynx cat has a high rate of heart disease, either as HCM or mitral valve dysplasia. In a 2012 study of 114 Sphynx cats, 34% were found to have an abnormal heart, with 16 cats having mitral valve dysplasia and 23 cats having HCM. These prevalences were found in cats with an average age of 2.62 years. Male cats developed more severe disease than female cats and often developed it earlier, at an average age of 19 months for males and 29 months for females. Since the prevalence of genetic heart disease is high in this breed, many breeders will recommend screening for HCM yearly.
As HCM progresses into an advanced stage, cats may experience congestive heart failure (CHF) or thromboembolism.
