Idiopathic Dilated Cardiomyopathy


Idiopathic dilated cardiomyopathy
Dilated cardiomyopathy


A disease of the heart muscle, normally beginning in the heart’s left ventricle (the heart’s main pumping chamber). The ventricle stretches and thins and is unable to pump blood as a healthy heart can. Not all patients experience symptoms, but for some it can be life-threatening.




Due to the lack of a large-scale, epidemiological study based on modern diagnostic criteria and imaging technology, the true prevalence of DCM has yet to be determined.  Many researchers and clinicians agree that the likely prevalence of DCM is more common than 1 in 2700 persons, and that it may be under-diagnosed.
