Summary

Pathophysiology of acromegaly cardiomyopathy is yet unclear and a specific treatment have not been indicated. It was already demonstrated the positive impact of phosphodiesterase type 5A (PDE5A) inhibition in several models of cardiomyopathy and in a model of endocrine cardiomyopathy due to type 2 diabetes mellitus. In this patients with diabetic cardiomyopathy it was demonstrated an improvement in cardiac kinetic, geometry and performance parameters and reduction of the ambulatory measurement of waist circumference.

This represents the first study that evaluate heart remodeling and performance changes and metabolic/immunological/molecular parameters after 5-months of Tadalafil 20 mg in Acromegaly cardiomyopathy.

The proposed research will test whether phosphodiesterase 5A inhibition could become a new target for antiremodeling drugs and to discover molecular pathways affected by this class of drugs and a network of circulating markers (miRNA) for the early diagnosis of acromegaly cardiomyopathy.

We hypothesize that:

* the signal molecules cGMP and cAMP could underlie the hypertrophic/profibrotic triggers related to this model of endocrine cardiomyopathy and that chronic inhibition of PDE5, activating cGMP signaling pathways, could improve cardiac remodeling due to acromegaly
* PDE5 inhibition could have a role in lipolytic regulation;
* neuroendocrine (e.g. natriuretic peptides) and metabolic markers and chemokines (e.g. MCP-1, TGF-ß) might relate with left ventricular (LV) remodeling in Acromegaly;
* there are neuroendocrine (e.g. natriuretic peptides), metabolic markers and chemokines (e.g. MCP-1, TGF-ß) related to cardiac disease in Acromegaly;
* miRNA expression \[miR-208a, 499, 1, 133, 126, 29, 233, 222, 4454\] might relate with LV remodeling in Acromegaly.
