The prevalence of<unk>  is unknown at the moment and has not been fully defined. About 20 families from around the world, whose members suffer from cardiogential syndrome, have been found in literature. However, the prevalence of familial dilated cardiomyopathy ranges from 30 to 50% cases, with 40% having an identifiable genetic cause. Dilated cardiomyopathy was originally classified as a rare disease, but the possibility of a familiar substrate was ignored. Dilated cardiomyopathy was later found to be a major cause of heart failure, especially among young patients. Dilated cardiomyopathy began to be identified as a systemic condition rather than an isolated disease. Even despite these major efforts and contributions, the incidence and prevalence of dilated cardiomyopathy remain unknown.
