Using platelet markers and blood flow analysis to predict stroke recurrence in patients with narrowed arteries
Official title: Platelet Expression of FcgammaRIIa and Arterial Hemodynamics to Predict Recurrent Stroke in Intracranial Atherosclerosis
Funded at University of California Los Angeles · NIH-11049115 · Data updated 2026-11-12
This study is looking at how certain markers in your blood and how blood flows in your arteries can help predict if you might have another stroke after experiencing a minor stroke or TIA, and it's for people who have recently had these types of strokes.

Who could benefit from this research
✓Could help
Ideal candidates for this research are individuals who have experienced a minor stroke or TIA due to significant narrowing of the arteries in the brain.
✕Less likely to help
Patients who have not experienced a stroke or TIA, or those with other unrelated medical conditions, may not benefit from this research.
What this research studies
This research investigates how specific markers on platelets and the flow of blood in arteries can help predict the risk of recurrent strokes in patients who have experienced a minor stroke or transient ischemic attack (TIA) due to intracranial atherosclerosis. By analyzing patient-specific CT angiography and computational fluid dynamics, the study aims to develop a precision model that quantifies the risk of future ischemic events. The research will involve recruiting a diverse group of 250 participants who have recently suffered from acute cerebral ischemia, allowing for a comprehensive understanding of the factors contributing to stroke recurrence.
Why it matters
Potential benefit: If successful, this research could lead to improved strategies for preventing recurrent strokes in at-risk patients.
How similar studies have gone: Previous research has shown promising results in using platelet markers and blood flow analysis to predict cardiovascular events, indicating that this approach may be effective.
