PET / CT With 18F-FDG (18F-fluorodeoxyglucose Positron Emission Tomography/Computed Tomography): Does it Optimize the I 123-MIBG (Iodine 123 Metaiodobenzylguanidine) Imaging Results in the Search for Discriminating Factors for the Implementation of an Implantable Defibrillator for Primary Prevention in Patients With Heart Failure of Ischemic Origin?

Overview
Brief Summary
The main objective of this study is to determine among the patients included a subpopulation that does not need a defibrillator.
This will be done by comparing the number of discordant segments (mismatch) between patients who have a severe arrhythmia (ventricular tachycardia or ventricular fibrillation) with appropriate electrical therapy within 3 years of monitoring and others. "Mismatch" in the definition of this objective is the usual definition: score 3.4 in I123-MIBG (Iodine 123 metaiodobenzylguanidine) and PET at 0,1,2.

Outcomes
Primary Outcomes
Presence/absence of a triggering of the defibrillator within 3 years of follow up
Time Frame: 3 years
The primary endpoint is the triggering of the defibrillator within 3 years of follow up. Mismatch segments will be studied as predictors of arrhythmia.
