Cardiomyopathy is characterized by progressive deterioration of the heart muscle; a large number of human genes have been implicated in the development of cardiomyopathy. Multiple different forms of familial cardiomyopathy have been modeled in Drosophila, including dilated cardiomyopathy (FBhh0000134), familial hypertrophic cardiomyopathy (FBhh0000409), and familial restrictive cardiomyopathy (FBhh0000425). A number of human genes are implicated in more than one form of cardiomyopathy; for these cases, reports of experimental results in flies have been organized by causative gene (see Related Diseases section, below) and cross-referenced under specific disease categories.
Cardiomyopathy associated with a high-fat diet (FBhh0000483) or a high-sugar diet (FBhh0000482) has also been studied in Drosophila. For a number of neurodegenerative or syndromic diseases that are associated with cardiomyopathy, that aspect of the disease has been investigated in flies; see Parkinson disease 2 (FBhh0000008), Huntington disease (FBhh0000003), and Noonan syndrome (FBhh0000131).

Cardiomyopathy refers to diseases of the heart muscle. The heart muscle becomes enlarged; it may become thick and more rigid or it may stretch and become thinner. As the condition worsens, the heart becomes weaker and less able to pump blood through the body and maintain a normal electrical rhythm. The result can be heart failure or irregular heartbeats (arrhythmias). The main types of cardiomyopathy are: (1) dilated cardiomyopathy, (2) hypertrophic cardiomyopathy, (3) restrictive cardiomyopathy and (4) arrhythmogenic right ventricular dysplasia.
