Study of Cardiac Lesions Angiogenesis by 68Ga-NODAGA-RGD Cardiac PET

Status Terminated

Clinical Trial 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.

Clinical Trial 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. ;
