What this Trial Is About

Stroke remains a major health burden worldwide. Many patients are severely disabled and stay in need of care. Mechanical thrombectomy has dramatically improved outcomes for stroke patients with large vessel occlusions, yet 40-50% of patients with successful recanalization remain severely disabled despite successful recanalization, a scenario called "futile recanalization". One of the causes for this lack of treatment effect is capillary obstruction, or "no reflow", potentially resulting from activated neutrophils and micrometer-sized blood clots. To address this issue, we employ digital holotomographic and atomic force microscopy to investigate the structural and chemical characteristics of blood and clot material in stroke patients and individuals at high risk of developing a stroke. Our study elucidates the association of activated neutrophils and microclots with stroke risk, and may be associated with clinical outcome, stroke ethology and reperfusion failure in patients with stroke. Leveraging label-free microscopy tools, could potentially lead to the discovery of new biomarkers for individualized stroke treatment and prevention, ultimately offering rapid identification of at risk patients and improving clinical outcomes
