Comparison of the new Canadian score to ABCD2 for TIA risk stratification in a common clinical setting

Abstract

INTRODUCTION Patients who have a TIA are at high risk of subsequent stroke, especially in the short term. The degree of risk is usually determined using clinical scores, most commonly ABCD2. Recently, a new score (Canadian TIA Score) has been proposed, which may be better in terms of prediction, and which includes more variables, both clinical and instrumental (i.e. presence of AF, carotid stenosis, any infarction on CT). We aimed at evaluating whether the two scores were reproducible, using data from our admission registry.
