Brain and Vascular Imaging Improve Prediction of Early Stroke After TIA

A risk score incorporating imaging with ABCD² variables refines stroke risk prediction.

Transient ischemic attack (TIA) confers a high short-term risk for stroke. However, most TIA patients are not at impending stroke risk, so identifying those at highest risk could improve clinical outcomes while optimizing the use of generally limited resources. ABCD², a validated prediction scale, uses clinical features at the time of presentation to stratify early stroke risk among TIA patients, but mounting data suggest that incorporating imaging information into this score may boost predictive accuracy (JW Neurol Apr 29 2008).

In this pooled multivariate logistic regression analysis of 2654 TIA patients from eight centers, researchers created two new scores, ABCD³ and ABCD³-I. The ABCD³ score (range, 0–9 points) incorporates ABCD² score v…
