Brief Summary

To compare the door-to-puncture time of patients with hyperacute ischemic stroke (between 4.5-6 hours after the onset of symptoms) treated in a standard stroke unit adherent to guidelines versus treated in Emergency Stroke Unit (a new stroke unit based on low-field magnetic resonance imaging).

Detailed Description

Mechanical thrombectomy is an effective reperfusion therapy for patients with acute ischemic stroke due to large vessel occlusion. Faster door-to-puncture time (DPT) is associated with significantly better clinical outcomes. With the development of low-field magnetic resonance imaging, it is poised to play an increasingly significant role in the early diagnosis and management of acute ischemic stroke. This prospective, multicenter, week-wise randomized controlled trial will compare the door-to-puncture time of patients with hyperacute ischemic stroke (between 4.5-6 hours after the onset of symptoms) 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).
