Outline of Final Research Achievements

Dilated cardiomyopathy (DCM) is a refractory disease whose diagnosis is not easy because its causes are various. We studied about usefulness of endomyocardial biopsy for the diagnosis of dilated cardiomyopathy. Immunostaining of myocardial structural proteins makes the diagnosis of specific cardiomyopathy such as arrhythmogenic right ventricular cardiomyopathy. We are able to investigate the pathogenesis of DCM by evaluation of sarcomere structure using electron microscopy. Moreover, necessary gene analysis in addition to pathogical diagnosis and clinical characteristics allows us to diagnosis lamin cardiomyopathy. Finally, those data is useful for the selection of therapy for several type of DCM.
