In this study, the investigators will evaluate the cardiac structure and function, focusing
on the myocardial water content and interstitial fibrosis, in patients with active acromegaly
in comparison with 1) healthy volunteers, 2) the same acromegalic patients that have received
efficient therapy.
The investigators hypothesize that the myocardial water content in acromegaly is increased as
these patients present with sodium and water retention and that this myocardial water
infiltration will improve with efficient treatment of the disease. They will thus assess
using CMRI, this parameter by measuring the myocardial transverse relaxation time (T2),
reflecting water content in the myocardium.
