TRANSIENT ISCHEMIC ATTACK UPDATE Transient Ischemic Attack: Risk Stratification and Treatment
A major challenge facing the physician evaluating patients with transient ischemic attack is determining which patients are at highest short-term risk of stroke. A number of stratification schemes have been recently developed incorporating easily obtainable clinical information about the individual patient. Further, emerging data suggest a role for brain and vascular imaging in risk stratificat...
متن کاملIs the ABCD score useful for risk stratification of patients with acute transient ischemic attack?
BACKGROUND AND PURPOSE A 6-point scoring system (ABCD) was described recently for stratifying risk after transient ischemic attack (TIA). This score incorporates age (A), blood pressure (B), clinical features (C), and duration (D) of TIA. A score <4 reportedly indicates minimal short-term stroke risk. We evaluated this scoring system in an independent population. METHODS This was a prospectiv...
متن کاملdifferentiation of true transient ischemic attack versus transient ischemic attack mimics.
background: previous literatures have shown a transient ischemic attack (tia) mimic rate of 9-31%. we aimed to ascertain the proportion of stroke mimics amongst suspected tia patients. methods: a prospective observational study was performed in ghaem hospital, mashhad, iran during 2012-2013. consecutive tia patients were identified in a stroke center. the initial diagnosis of ...
متن کاملDiffusion-Weighted Imaging and Diagnosis of Transient Ischemic Attack
OBJECTIVE Magnetic resonance (MR) diffusion-weighted imaging (DWI) is sensitive to small acute ischemic lesions and might help diagnose transient ischemic attack (TIA). Reclassification of patients with TIA and a DWI lesion as "stroke" is under consideration. We assessed DWI positivity in TIA and implications for reclassification as stroke. METHODS We searched multiple sources, without langua...
متن کاملTransient ischemic attacks--definition, risk prediction and urgent management.
Recent evidence suggests that the risk of stroke in first few months after transient ischemic attack is higher than that was previously realized. There are clinical and imaging predictors which help in risk stratifying the patients to identify the high risk group who need immediate hospitalization and urgent evaluation. Recent advances in neuroimaging have revolutionized the evaluation of these...
