![]() Clinical scores have moderate prognostic accuracy for stroke after TIA. Among clinical items of each score, duration of symptoms, previous TIA, hemiparesis, speech disturbance, gait disturbance, previous cerebral ischemic lesions, and known carotid artery disease were independent predictors of stroke. ![]() Considering the best cut-off of each score, only ABCD 2 > 3 showed a sensitivity of 100% only in the prediction of stroke within 7 days. AUROCs ranged from 0.66 to 0.75, without statistically significant differences at each time-point. ABCD 2, ABCD 2-I, and OTTAWA scores were significantly higher in patients who developed a stroke. Thirty-nine (7.7%) had a stroke within 1 year from the TIA: 9 (1.7%) and 24 (4.7%) within 7 and 90 days, respectively. Five hundred three patients were included. Single-centre, retrospective study including patients with TIA admitted to the Emergency Department of our third-level, University Hospital, between 20. The objective is to compare the accuracy of ABCD 2, ABCD 2-I, and OTTAWA scores in the prediction of a stroke at 7, 90 days, and 1 year in patients presenting with TIA. Many clinical prediction scores have been proposed to assess the risk of stroke after TIA however, studies on their clinical validity and comparisons among them are scarce. Transient ischemic attack (TIA) is a neurologic emergency characterized by cerebral ischemia eliciting a temporary focal neurological deficit.
