NCT06522269

Brief Summary

To compare the prognosis of patients with hyperacute ischemic stroke (who arrive at the emergency department within 4.5 hours of symptom onset) managed in a standard stroke unit adherent to guidelines versus managed in Emergency Stroke Unit (a new stroke unit based on low-field magnetic resonance imaging).

Outcome Measures

Primary Outcomes (1)

  • The utility-weighted modified Rankin Scale (uw-mRS) at 90 days (± 7 days).

    The utility-weighted modified Rankin Scale (uw-mRS) at 90 days (± 7 days). Scores on the modified Rankin scale range from 0 (no neurologic deficit) to 6 (death).

    at 90 days (± 7 days)

Secondary Outcomes (14)

  • Ordinal (shift) analysis of modified Rankin Scale (mRS) at 90 days (± 7 days).

    at 90 days (± 7 days)

  • Excellent functional outcome (Modified Rankin Scale score, mRS 0-1) at 90 days (± 7 days).

    at 90 days (± 7 days)

  • Good functional outcome (Modified Rankin Scale score, mRS 0-2) at 90 days (± 7 days).

    at 90 days (± 7 days)

  • A 30% reduction (improvement) from baseline to 24 hours in the NIHSS score.

    from baseline to 24 hours in the NIHSS score.

  • The time from symptoms onset to intravenous thrombolysis decision.

    up to 4.5 hours from symptom onset

  • +9 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years;
  • Patients who arrive at the emergency department within 4.5 hours of symptom onset\* (\*Symptom onset is defined by the "last seen normal" principle);
  • Presenting with ischemic stroke symptoms;
  • Pre-stroke mRS score 0-1;
  • Baseline NIHSS score ≥ 5;
  • Eligible for rt-PA/TNK thrombolysis;
  • Informed consent signed.

You may not qualify if:

  • Baseline NIHSS score \< 5;
  • Unable to undergo MRI because of claustrophobia;
  • Patients with cardiac pacemaker/brain pacemaker/insulin pump implantation;
  • Definite contraindication for rt-PA/TNK thrombolysis;
  • Patients with postictal hemiparesis (Todd's paralysis) or those with concomitant neurological/psychiatric conditions who are unable or unwilling to cooperate;
  • Pregnant women, nursing mothers, or reluctance to use effective contraceptive measures during the period of trial;
  • Participation in other interventional randomized clinical trials within 3 months before enrollment;
  • Patients deemed unsuitable for participation in this trial by the investigator or those for whom participation in this trial may result in greater risks.
