[Prognosis of hypertrophic and dilated cardiomyopathy].

Hypertrophic and dilated cardiomyopathies are a heterogeneous disease, both clinically and genetically. Hypertrophic cardiomyopathy(HCM) is important causes of sudden cardiac death and death from congestive heart failure, although HCM has a relatively benign prognosis. The prognosis of dilated cardiomyopathy(DCM) has improved due to advances in earlier diagnosis and therapy, however, sudden cardiac death and death from congestive heart failure still occur in DCM. Accordingly, it is of importance to know possible risk factors on risk stratification for a high-risk group in HCM and DCM. Possible risk factors may contribute to the construction of therapeutic strategies for the prevention of sudden cardiac death or death from congestive heart failure in patients with HCM and DCM.
