PET/MR in Post Stroke Cardiac Inflammation Study
Patients with stroke have a 25x higher risk of cardiovascular complications within the first 30 days of the event compared to individuals without stroke. The mechanisms behind these complications are not well understood. Evidence suggests that inflammation plays a central role. With the present proof-of-concept prospective cohort study, the investigators aim to demonstrate that patients develop cardiac inflammation after stroke by performing positron emission tomography (PET) magnetic resonance imaging (MRI) of the heart within 15 days after stroke. As a secondary aim, the investigators will evaluate whether post-stroke cardiac inflammation persists at 3 months after stroke. The control group will be comprised of age- and sex-matched individuals without stroke.

• Patients with acute ischemic stroke in the right or left MCA territory, admitted to University Hospital, London Health Sciences Centre (LHSC) or evaluated at LHSC's Urgent TIA and Stroke Prevention Clinic. Acute ischemic stroke is defined as acute onset focal symptoms matching an acute brain infarct documented on a Head CT or on diffusion weighted imaging (DWI) MRI of the brain showing restricted diffusion.
