What are the prognosis and prognostic factors for mortality in patients with idiopathic dilated cardiomyopathy in Japan?
A nationwide survey in Japan identified five independent predictors of mortality in idiopathic dilated cardiomyopathy, which can be combined into a clinical predictive score.
Miura et al. (2008) conducted a cohort in Idiopathic dilated cardiomyopathy (n=1,554). Observational (Prognostic factors) was evaluated on 5-year survival rate (for those diagnosed in 1998). In a nationwide Japanese cohort of patients with idiopathic dilated cardiomyopathy, the 5-year survival rate was 78.6%, with male sex, older age, higher NYHA class, higher LVD index, and lower LVEF identified as independent predictors of mortality.
