Edlow JA. Managing patients with transient ischemic attack. Ann Emerg Med. 2018;71(3):409-415.
Transient ischemic attack (TIA) is a neurologic emergency with tremendous public health significance, and appropriate risk stratification has important ramifications. A TIA patient often presents without any neurologic deficit, but the incidence of a clinically significant acute ischemic stroke 48 hours later is reportedly as high as 4.8%. Rapidly implementing multiple interventions (“secondary stroke prevention”) can reduce the outcome of stroke by up to 80%. This article reviews the management of neurologically intact patients diagnosed with TIA in the emergency department (ED). Clinical diagnosis, risk stratification, diagnostic testing, treatment, and disposition are also reviewed.
