Ildstad F, et al. - Using data obtained by telephone follow-up and registry data from the Norwegian Stroke Register, researchers evaluated stroke risk at 1 week, 3 months, and 1 year following transient ischemic attack (TIA), and determined the predictive value of the dichotomized ABCD² score (0–3 vs 4–7) at each time point. They conducted a prospective, multicenter study in Central Norway that included patients with a TIA within the previous 2 weeks from October 2012 to July 2014. The cumulative stroke incidence in 1 week, 3 months, and 1 year of TIA was 0.9%, 3.3%, and 5.4%, respectively. The accuracy of the ABCD² score provided by c-statistics at 7 days, 3 months, and 1 year was 0.62, 0.62, and 0.64, respectively. Overall, they found a low risk of stroke after TIA. The ABCD² score did not distinguish between low- and high-risk patients reliably, suggesting that it might be less useful in populations with a low risk of stroke after TIA.
