ABCD2 Score Might Be Poor Predictor of Stroke Risk

Sensitivity of the score was poor in a cohort of emergency department TIA patients with a 1.8% incidence of stroke at 7 days.

The ABCD2 score (Age, Blood pressure [BP], Clinical features, Duration of symptoms, and Diabetes) was developed to predict which patients with transient ischemic attack (TIA) might be at high risk for stroke, but it has not been prospectively validated in a large study. In this prospective, multicenter Canadian study, researchers assessed the accuracy of the ABCD2 score in 2056 patients (mean age, 68) with emergency department diagnoses of TIA or minor stroke.

Physicians completed ABCD2 data forms and calculated the score for each patient. (The score assigns 1 point each for age ≥60, BP ≥140/90 mm Hg, impaired speech without weakness, duration of symptoms 10–59 minutes, and diabetes and assigns 2 points each for unilateral weakness and durat…
