Blood Proteome Profiling Identifies Biomarkers in Ischemic Stroke

Capital Medical University80 enrolled

Overview

Endovascular thrombectomy and intravenous thrombolysis have become key therapeutic approaches for acute ischemic stroke. However, due to time window limitations, many patients are unable to receive reperfusion therapy, and the majority only receive supportive treatment. Ischemic stroke-related complications, including edema and infection, gradually subside after 7 days post-stroke, with the patient's condition generally stabilizing. Endogenous repair mechanisms will play a critical role in the coming months. This study aims to predict prognostic biomarkers for ischemic stroke patients who have not undergone reperfusion therapy, using blood proteomics data. All samples in our study are derived from this experiment. Our goal is to elucidate the molecular mechanisms underlying post-reperfusion prognosis and to provide insights for optimizing stroke treatment strategies.

Outcomes

Primary Outcomes

Primary Outcome Measures:

Modified Rankin Scale score (mRS) at 90 days The Modified Rankin Scale (mRS) at 90 days was used to assess functional outcomes. The mRS is a widely utilized scale to measure the degree of disability or dependence in daily activities among stroke patients. Minimum value: 0 (indicating no symptoms or disability) Maximum value: 6 (indicating death) Interpretation: Higher scores represent worse outcomes, reflecting greater levels of disability or mortality.

Time frame: 3 months
