A genetic predisposition towards hypertrophic cardiomyopathy appears in some genetic lines of the Maine Coon population. In extreme cases, this condition can result in the sudden death of what appears to be an otherwise healthy animal. It can be detected by regular cardiac ultrasounds of pets between the ages of 3 and 6, the age at which the disease becomes detectable. Responsible breeders, in an effort to reduce the occurrence of HCM, now screen their animals long-term and make this information available to potential pet buyers.

In the past, Taurine deficiency was a common cause of dilated cardiomyopathy in all cats, including Maine Coons. Since the pet food industry started adding Taurine to cat food, this kind of cardiomyopathy is increasingly rare. Taurine-related cardiomyopathy can be cured with the addition of the nutrient to the diet, but genetic HCM causes a permanent enlargement of the left ventricle and is rarely treatable.

Other potential health problems include hip dysplasia and Polycystic Kidney Disease. However, Maine Coons are generally quite healthy and resilient animals.
