Routine histopathological evaluation of the explanted heart is essential to confirm the etiology of heart failure, especially in cases clinically diagnosed as dilated cardiomyopathy. In addition, routine follow-up through endomyocardial biopsies shows that acute cellular rejection is still a frequent complication after a heart transplant, especially within the first year, and that antibody-mediated rejection has a low incidence in our population.

Our results indicate that atorvastatin, independently of its cholesterol-lowering capacity, lowers the ACE/ACE2 ratio to normal values and attenuates the development of adverse remodeling in the diabetic heart.

Treatment with SPL, through independent glucose effects, reduces the loss of podocytes and the progression of DN morphological changes. These results suggest that these effects are mediated, at least in part, by the inhibition of TGF-β1 mRNA expression.
