Scientists track hidden blood clues in stroke patients
NCT ID NCT07354321
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at blood markers related to inflammation and clotting in people who have had a stroke or a brain bleed. Researchers want to see how these markers change over time and differ between patients with complications. About 499 adults will give blood samples at five time points and take a memory test at three months. No treatment is given; the goal is to learn more about these conditions.

Inclusion Criteria: * Patients aged 18 years or older * Admitted within 8 hours of an acute ischemic stroke (AIS) due to large-vessel occlusion (LVO) or medium-vessel occlusion (MeVO) of the anterior circulation, with a NIHSS (National Institutes of Health Stroke Scale) score \> 5 (M1, M2, M3, A1, A2, A3, P1, P2) * Or admitted within 36 hours of acute symptoms related to aneurysmal subarachnoid hemorrhage (SAH) Exclusion Criteria: * Patients with pre-existing functional and/or cognitive disability (modified Rankin Scale, mRS \> 1) * Patients under legal protection or guardianship * Patients with secondary hemorrhagic transformation of an acute ischemic stroke Patients with acute ischemic stroke and NIHSS \> 5 without LVO or MeVO of the anterior circulation on imaging will be secondarily excluded. Perfusion imaging will not be performed as part of the research protocol. Excluded patients will be replaced.
