18F-deoxyglucose (FDG) PET-CMD
Monocentric, Prospective, Uncontrolled Pilot Study of Extra Cardiomyocytary Fixation Profile in 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography in Patients With Dilated Cardiomyopathy.
18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) may have application in a promising tool for identification of myocardial inflammation in patients with dilated cardiomyopathy (DCM).Therefore, the purpose of the study is to confirm the hypothesis of the fixation of FDG in non cardiomyocyte cells in a number of patients with DCM, to specify the frequency and describe the different binding profiles in comparison with MRI data.
Patients will perform an ethologic evaluation of a non ischemic DCM with in a cardiac MRI.
All patients will have with in 4 weeks after the MRI a 18F-fluorodeoxyglucose (FDG) PET. A high fat and low carbohydrate diet and an heparin injection will be prescribed to patients before this FDG PET.
Patients will be identified as FDG+ or FDG -. The clinical status of the patient will be completed by a 12 months evaluation.

Determine the percentage of patients with a diagnostic potential of the 18F-FDG PET in the detection of a significant non-cardiomyocyte hypermetabolism
Time Frame: 12 months
|
We want to objective a significant hypermetabolic extra-cardiomyocyte by 18F-FDG PET examination, in favor of myocardial inflammation in patients with DCM diagnosed for more than two weeks without new ventricular arrhythmias or second AVB or third degree, and who responded to the usual treatment in the first two weeks of treatment.
