[Idiopathic congestive cardiomyopathy. Absence of histopatological for adrenergic hyperactivity (author's transl)].

Extensive histopathological investigation of hearts from patients with idiopathic congestive cardiomyopathy failed to reveal "myofibrillar degeneration", a lesion ascribed specifically to cathecolamine cardiac overstimulation. Morphological support of the theory of adrenergic hyperactivity in the development and progression of this disease is not provided by the present study.
