Brief Summary:
An observational, cross-sectional, longitudinal, microdosing Position Emission Tomography (PET) imaging study to investigate platelet derived growth factor receptor beta (PDGFRß) expression in the heart of patients with high or low risk of heart failure after a ST-Elevation Myocardial Infarction (STEMI) after a percutaneous coronary intervention (PCI) with a stent procedure, as well as in patients with heart failure with preserved ejection fraction (HFpEF) and healthy individuals.
Detailed Description:
PDGFRß is a biomarker for pericytes which are identified as the progenitor of myofibroblast and fibroblast responsible for extra-cellular matrix proteins deposition in fibrotic heart. The Positron Emission Tomography (PET) tracer \[68Ga\]Ga-Dodecane tetra acetic acid (DOTA)-Cys-ATH001 is a marker for fibrogenic cells by targeting the surface receptor PDGFRß.
Four cohorts are examined by Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI) or separate Positron Emission Tomography/Computed Tomography (PET/CT) and MRI using the following imaging protocol: 15O-H20 (myocardial perfusion, up to 10 min dynamic PET scan), \[68Ga\]Ga-DOTA-Cys-ATH001 (PDGFRß PET, up to 60 min dynamic + static full body PET scans), and Gd-MRI (extracellular volume in infarct, around 10 min MRI scan).
