Stroke is the leading cause of death in China, and large vessel occlusion (LVO) stroke is the type of ischemic stroke with the highest mortality and disability rate. Clinical guidelines recommend early interventions through intravenous thrombolysis, bridging therapy, or endovascular treatment to salvage ischemic brain tissue. Therefore, early identification of LVO stroke is of vital importance for prehospital emergency and referrals. Currently, numerous assessment tools for predicting LVO stroke have been developed, such as the prehospital acute stroke triage (PAST) scale, emergent large vessel occlusion screen (ELVO) scale, Cincinnati prehospital stroke severity scale (CPSSS), emergency medical stroke assessment (EMSA) scale and large artery intracranial occlusion stroke (LARIO) scale. This article focuses on the content and prediction efficiency of these assessment tools developed in recent years for prehospital prediction of LVO stroke, aiming to facilitate their applications in clinical practice.
