Abstract
We investigated transient ischemic attack (TIA) patients who were admitted to our hospital within 48 hours to clarify their risk of an acute stroke within 90 days using the ABCD2 score. An acute ischemic stroke occurred in 8 patients (5%, stroke group) within 7 days of the onset of TIA (median, 2.5 days), and half of these were lacunar infarctions. The blood pressure (BP) on admission in the stroke group was significantly higher than that in the non-stroke group. Multivariate analysis revealed that the total but not the individual items (age, BP, clinical features, duration of symptoms, diabetes mellitus) of the ABCD2 score tended to be a risk factor for ischemic stroke early after admission. The frequency of patients with both atrial fibrillation and arterial stenosis/occlusion was significantly higher in the stroke group than in the other group. It seems that a high BP, high ABCD2 score, and a combination of atrial fibrillation and occlusive arterial disease are risk factors for acute strokes in TIA patients.
