Myocardial Infarction Clinical Trial
Official title:
Neuroinflammation After Myocardial Infarction - Imaging Substudy
The purpose of the study is to see if positron emission tomography and magnetic resonance imaging (PET/MRI) with an investigational drug called [18F]DPA-714 will show inflammation in the brain after a heart attack. This study may help physicians and researchers better understand the role of brain inflammation in heart disease and develop new treatments to protect the brain.
The primary objective of this study is to measure the concentration and the regional brain distribution of activated brain microglia/macrophages using the PET ligand [18F]DPA-714 in individuals with recent AMI. The basic premise is that AMI leads to systemic inflammation that includes inflammation in the brain. The PET tracer [18F]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation. The estimates of brain TSPO binding in patients with recent AMI will be compared to a matched group of patients who have undergone a recent elective PCI procedure. ;
