Endothelial Microvesicles: A Plasma Biomarker of Futile Recanalization Post Intravenous Thrombolysis in Patients with Stroke

Investigating futile recanalization indicators is very important. Here, we explored plasma endothelial microvesicles (EMVs) as biomarkers for recombinant tissue plasminogen activator (rtPA)-treated acute ischemic stroke. This study prospectively enrolled 195 acute IS patients who underwent rtPA and measured plasma EMVs levels via fluorescence nanoparticle tracking analysis at baseline, 24 h and 90 days. Early futile recanalization was assessed by transcranial Doppler and the National Institutes of Health Stroke Scale. The ROC curves and corresponding areas under the curve (AUC) of the EMVs were analysed. The plasma EMVs levels at baseline and 24 h were positively related to both early and la
