Myocardial Infarction, Acute Myocardial Reperfusion Chronic Ischemic Heart Disease | Other: 68Ga-NODAGA-RGD PET/CT Diagnostic Test: 82-Rb PET/CT as part of standard care, not a comparator | Not Applicable |
Several animal studies have demonstrated the expression of αvβ3 integrins on the surface of the endothelium present in neovessels in formation, especially during neoangiogenesis after myocardial ischemic injury.
68Ga-NODAGA-RGD is a positron-emission-tomography (PET) ligand targeted towards αvβ3 integrins. αvβ3 integrins could potentially act as a biomarker for the follow-up of heart infarction.
In the present study, 68Ga-NODAGA-RGD PET/CT imaging is a tool to understand and evaluate tissue repair after heart lesion and its evolution allowing a better management of patients with occluded artery.
Three groups of patients are included : patients with acute infarction, patients with acute infarction requiring reperfusion treatment and patients with chronic ischemic occlusion.
Each patient would benefit from a 82Rb (82rubidium) PET/CT as part of standard management and from a 68Ga-NODAGA-RGD PET/CT as part of the present study.
Patients from groups 1 and 2 will have 3 sets of both exams : one after the ischemic event, one at one month and another at 3 months post event.
Patients form group 3 will have a set of both exams before reperfusion treatment and one at 2 months after reperfusion.
