Platelet markers and blood flow to predict recurrent stroke in intracranial artery disease

Official title: Platelet Expression of FcgammaRIIa and Arterial Hemodynamics to Predict Recurrent Stroke in Intracranial Atherosclerosis

Funded at University of Southern California · NIH-11504575 · Data updated 2026-11-12

Researchers will look at how a platelet protein (FcγRIIa) and blood flow patterns from CT angiography predict who might have another stroke after a minor stroke or TIA caused by intracranial artery disease.

Who could benefit from this research

Could help

Adults with acute cerebral ischemia due to 50-99% intracranial atherosclerotic disease diagnosed on CTA.

Less likely to help

Patients without intracranial artery disease or with non-ischemic etiologies may not benefit from this risk model.

What this research studies

This study will combine patient-specific imaging data with blood test results to create a personalized risk model for recurrent stroke after ICAD. It will measure FcγRIIa expression on platelets and use CTA-derived wall shear stress calculations to understand how these factors interact with anti-platelet therapy and platelet reactivity. The project plans to enroll about 250 adults with acute ischemia within 72 hours of onset across six sites with diverse populations, and follow them to assess recurrent events over time. The goal is to identify high-risk patients and inform precision prevention strategies.

Why it matters

Potential benefit: If successful, the work could lead to personalized prevention strategies that reduce the risk of another stroke in ICAD patients.

How similar studies have gone: Early data suggest platelet FcγRIIa expression and wall shear stress may identify those at higher risk, but this multi-site model is novel in its integration for ICAD.
