Prognostic Biomarkers for Selective Intra-Arterial Cooling Infusion Combined with Endovascular Thrombectomy in Acute Ischemic Stroke Based on Proteomics and Metabolomics.
Trial Parameters
Brief Summary
Endovascular Thrombectomy has emerged as a pivotal treatment modality for acute ischemic stroke. However, despite successful thrombus removal, a substantial proportion of patients still experience poor outcomes. Selective intra-arterial cooling has shown promise in decelerating stroke progression and providing neuroprotection. This study aims to identify biomarkers associated with the combination of selective intra-arterial cooling infusion and endovascular thrombectomy in the treatment of ischemic stroke by integrating proteomics and metabolomics data. Our study is based on the multicenter RCT study "Safety and Efficacy of Selective Intra-Arterial Cooling Infusion Combined With EVT in Acute Ischemic Stroke." All samples were derived from this experiment. Our objective is to elucidate the molecular mechanisms underlying the prognostic impact of this combined therapeutic approach, providing insights to optimize stroke treatment strategies.
Eligibility Criteria
Inclusion Criteria: * Age ≥18 and ≤80. * Clinical signs consistent with acute ischemic stroke with large vessel occlusion in the anterior circulation (intracranial segment of the internal carotid artery, middle cerebral artery M1 segment) demonstrated with CTA/MRA/DSA. * NIHSS score obtained prior to randomization ≥6 and ≤25. * Modified Rankin Scale ≤ 1 prior to qualifying stroke. * Arterial puncture performed within 24 hours from symptom onset or LKW. * For the patients with symptom onset within 6 hours, the ASPECT score ≥6; for the patientswith onset within 6-24 hours, the therapy should meet the imaging criteria of DAWN or DEFUSE-3 trial. * Patient/Legally Authorized Representative has signed the Informed Consent Form. Exclusion Criteria: * Baseline CT/MRI confirms the presence of multiple vascular territory acute strokes. * Baseline CT/MRI confirms the presence of arterial dissection. * Evidence of intracranial hemorrhage or hemorrhagic transformation before thrombectomy. * Known a
