Abstract:
The Age, Blood Pressure, Clinical Features, Duration, and Diabetes plus Dual TIA (ABCD 3 -I) score is recommended to predict the risk of early stroke after transient ischemic attack. The aim of this study was to validate the predictive value of the ABCD 3 -I score and compare the accuracy of the Age, Blood Pressure, Clinical Features, Duration, and Diabetes (ABCD 2 ) and ABCD 3 -I scores in a Chinese population. Methods— Data were prospectively collected from patients who had transient ischemic attack, as defined by the World Health Organization time-based criteria. ABCD 2 and ABCD 3 -I scores were available within 7 days of the index transient ischemic attack. The predictive outcome was stroke occurrence at 90 days. The receiver-operating characteristic curves were plotted, and the C statistics were calculated as a measure of predictive ability. The comparison of the area under the receiver-operating characteristic curve (area under the curve) was performed by Z test. Results— Among 239 eligible patients, the mean age was 57.4±13.32 years, and 40.2% of the patients were women. The incidence of stroke at 90 days was 12.1%, which ranged from 0% in patients with lower ABCD 3 -I scores (0–3) to 40.91% in those with higher scores of 8 to 13 ( P for trend 〈 0.0001). Moreover, the C statistic of ABCD 3 -I scores (0.825; 95% confidence interval, 0.752–0.898) was statistically higher than that of ABCD 2 scores (0.694; 95% confidence interval, 0.601–0.786; P 〈 0.001). Conclusions— The ABCD 3 -I score had a higher predictive value than the ABCD 2 score for assessing the risk of early stroke after transient ischemic attack in a Chinese population.
