TIA-to-Stroke Risk Prediction Easy As A-B-C-D2

TIA-to-Stroke Risk Prediction Easy As A-B-C-D² - CME Teaching Brief® - MedPage Today: "The ABCD2 score is based on age, blood pressure, clinical features, diabetes, and TIA duration. It predicts stroke risk during the two-day window during which half of subsequent strokes occur, the researchers said.

Although the study validated the utility of both the existing California and ABCD scales, the new tool is likely to be more useful for emergency management and creates a single standard for use in clinical care and public education, Dr. Johnston and colleagues said.

'Identifying those at highest and lowest risk of stroke in the first days and weeks after a TIA would allow more appropriate utilization of costly secondary prevention strategies, including hospitalization,' they wrote.

'The California Score was developed to predict stroke within 90 days and the ABCD score predicts seven-day stroke risk, whereas the two-day stroke risk is often most relevant for decisions about necessity of emergent evaluation and observation,' they added."
