Abstract
Degeneration of the heart muscle in cardiomyopathic (CM) hamsters follows a staging pattern which thus far has received little explanation. The ventricular myosin changes with time course of the disease (1) and the impaired responsiveness to catecholamines (2) in these animals are two untoward features that led us to investigate the thyroid function. It is commonly accepted that the pathologic changes in myopathic hearts become evident after 30 days of age (3–7). This stands for a depressed oxidative metabolism or changes in activity of ATPases which concur to the necrotizing process (8, 9). Similar metabolic inadequacies have been equally observed in hypothyroid or diabetic hearts (10, 11) and it seemed all important to appraise the vulnerability of heart muscle cells in hamsters as it may relate to thyroid function.
