Brief Summary:
The study is about exploring physiological angiogenesis linked to tissue repair in patients with acute heart infarction or chronic heart ischemia by means of 68Ga-NODAGA-RGD PET/CT imaging.

Condition or disease Intervention/treatment Phase
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

Detailed Description:

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.
