Brief Summary

The goal of this observational study is to understand acute anterior circulation large artery occluded minor stroke (LVO-MIS) evolution using magnetic resonance spectroscopic imaging evaluation. The main questions it aims to answer are:

  1. 1.Neurometabolic predictors of early neurological deterioration and functional outcome;
  2. 2.Temporal and spatial dynamic changes of the neurometabolites from the acute stage (within 24 hours), through the subacute stage (5-7 days), to the chronic stage (90 days);
  3. 3.Temporal and spatial dynamic changes of the neurotransmitters GABA, glutamate, and glutamine from the acute stage to the chronic stage;
  4. 4.Brain regions exhibiting changes in whole-brain metabolic network connectivity.

Outcome Measures

Primary Outcomes (1)

  • Early neurological deterioration

    It is defined as an increase of ≥4 points from baseline NIHSS at hospital arrival, and excluding non-ischemic causes such as hemorrhagic transformation and epilepsy.

    24 hours

Secondary Outcomes (4)

  • Neurological functional outcome

    90 days

  • Composite Temporal and spatial dynamic changes of the neurometabolites

    acute stage (within 24 hours), the subacute stage (5-7 days) and the chronic stage (90 days)

  • Composite Temporal and spatial dynamic changes of the neurotransmitters

    acute stage (within 24 hours), the subacute stage (5-7 days) and the chronic stage (90 days)

  • Changes in whole-brain metabolic network connectivity

    acute stage (within 24 hours), the subacute stage (5-7 days) and the chronic stage (90 days)

Study Arms (1)

LVO-MIS

Acute minor ischemic stroke induced by large vessel occlusion (LVO-MIS) within 24 hours

Sampling MethodNon-Probability Sample
Study Population

Patients who are older than 18 years of age diagnosed with acute mild ischemic stroke with large vessel occlusion (LVO-MIS) within 24 hours of onset will be enrolled into the study.

You may qualify if:

  • Adult (age ≥ 18 years) patients presenting with symptoms consistent with acute ischemic stroke due to occlusion of the intracranial internal carotid artery and/or M1 or M2 segment of the middle cerebral artery;
  • Patients with mild symptoms at admission (National Institutes of Health Stroke Scale (NIHSS)\<6);
  • Baseline multimodal-CT imaging, including NCCT, CTA and CTP, performed at the trial-site hospital;
  • Time from symptom onset or last known normal to enrollment is less than 24 hours;
  • Patient or legal representative willing to comply with protocol requirements and data collection procedures, understand and sign informed consent.

You may not qualify if:

  • A pre-incident mRS ≥ 1 point before onset;
  • Previous clear history of cerebral infarction, cerebral hemorrhage, brain tumor and other diseases that affect cerebral metabolism;
  • Intolerance or non-cooperation with magnetic resonance examination;
  • Severe cardiac, hepatic, renal impairment or other systemic serious advanced diseases;
  • Pregnancy or lactation;
  • Life expectancy is less than 3 months;
  • Other conditions that, in the opinion of the investigator, are not suitable for participation in this study or may pose a significant risk to the patient (such as inability to understand and/or comply with study procedures and/or follow-up due to psychiatric disorders, cognitive or emotional disorders).
