Who might be able to join this trial:
For the Symptomatic Group (people who have had a stroke or related event):
- People between 30 and 85 years of age
- People who have had a recent stroke shown on a specific type of brain scan (MRI), caused by a clot travelling from a narrowed artery in the brain (at least 60% narrowed), and where tiny clots moving through the blood have been detected using a specialised ultrasound test
- People who have no medical reason preventing them from having the imaging tests used in this study
- People who understand what the study involves and have given their written agreement to take part
For the Asymptomatic Group (people with a narrowed brain artery but no stroke):
- People between 30 and 85 years of age
- People who have a severely narrowed artery in the brain (more than 60% narrowed, detected on MRI scan) but have no signs of stroke in the area supplied by that artery on brain scans
- People in whom no tiny moving clots have been detected on the specialised ultrasound test
- People who have no medical reason preventing them from having the imaging tests used in this study
- People who understand what the study involves and have given their written agreement to take part
Who may not be able to join:
- People whose stroke was caused by something other than narrowing of the brain arteries — for example, a clot from the heart, a condition called Moyamoya disease, or disease of very small blood vessels
- People who also have a significant narrowing (more than 50%) in a large artery in the neck called the internal carotid artery
- People with a higher risk of bleeding — including those with an active stomach ulcer, a major bleed anywhere in the body within the past 30 days, a low platelet count, or a blood clotting problem (confirm with trial site for specific test values)
- People with a health condition that would make it difficult to follow the study's requirements or complete the full study
