For example, cardiomyopathy is very often present in cases of undiagnosed feline hyperthyroidism in which the excess thyroid hormones cause the heart to work overtime, thus wreaking havoc on its function over a period of time.
These include defective heart valves, hypertrophic cardiomyopathy (enlarged heart muscle), holes or abnormal openings in the walls of the heart (septal defects), aortic aneurysm, or other congenital heart disease.
Various forms of heart disease often accompany FA, including cardiomyopathy (enlargement of the heart), myocardial fibrosis (formation of fiber-like materials in heart muscles), and cardiac failure.
Other common problems include heart valve dysfunction, thickening of the heart muscle (cardiomyopathy), enlarged spleen and liver, clouding of the cornea, hearing loss, and carpal tunnel syndrome.
In an almost opposite mechanism to dilated cardiomyopathy, the hypertrophic condition results in heart muscle tissue that has thickened to the point of being unable to pump and function properly.
