Pathogenesis of Dilated Cardiomyopathy

Pathogenesis and therapy of autoimmunity-induced dilated cardiomyopathy.

Myocarditis and dilated cardiomyopathy can potentially originate from autoimmune responses. Although genetic predisposition, viral infection, molecular mimicry, and oxidative stress are potential contributing factors to dilated cardiomyopathy, the underlying mechanism (s) has not been fully elucidated. Autoantibodies (AABs) against cardiotropic targets such as ss-adrenergic receptors, mitochond...

Viral infection and the pathogenesis of dilated cardiomyopathy.

Long-term follow-up studies of patients with suspected viral myocarditis reveal progression to dilated cardiomyopathy (DCM) in a significant number of cases. Thus, an underlying viral etiology has been hypothesized in the pathogenesis of ongoing heart disease that leads to DCM. Recent application of molecular biology in clinical diagnosis has strengthened this hypothesis. By use of probe hybrid...

Dilated Cardiomyopathy

Background. Immunization with cardiac myosin induces experimental autoimmune heart disease in genetically predisposed mice. These mice produce heart-specific autoantibodies, some of which are directed against the cardiac myosin isoform. Methods and Results. We have reported the presence of circulating heart-specific autoantibodies in 26% of patients with idiopathic dilated cardiomyopathy (DCM) ...
