Key result
Insulin treatment initiated after 12 weeks of diabetes reversed most structural myocardial changes within 6-12 weeks, though scattered myofibril loss and extracellular matrix retention persisted.

Insulin may partially reverse diabetic cardiomyopathy changes in rats; hypothesis-generating and should not alter human practice.
Does insulin treatment reverse structural manifestations of diabetic cardiomyopathy in rats?
Insulin treatment can reverse many, but not all, structural manifestations of diabetic cardiomyopathy in a rat model, suggesting both reversible physiologic adaptations and irreversible degenerative changes.
Ed W. Thompson (1988) studied Diabetic cardiomyopathy. Insulin treatment vs. Untreated diabetes was evaluated on Structural effects upon the contractile and supporting elements of the myocardium. Insulin treatment initiated after 12 weeks of diabetes reversed most structural myocardial changes within 6-12 weeks, though scattered myofibril loss and extracellular matrix retention persisted.
