[Primary cardiomyopathies and disorders of myocardial energy metabolism: causes or consequences?].

In this review paper, the authors summarize the studies which support the theory that a defect in production of energy by the myocardial cells is a determinant factor in the genesis and/or aggravation of dilated cardiomyopathy. Points that are common to this metabolic theory and to the other pathogenetic mechanisms usually described (notably viral or toxic mechanisms) are presented.
