Abstract:
Objective Many studies have proved that the ABCD 2 score can be used to predict early stroke risk after transient ischemic attack ( TIA) , but few reports are seen on its predictive value for early stroke risk after TIA in different types of circulation . This article aimed to evaluate the ABCD 2 score in predicting early stroke risk following anterior or posterior circulation TIA . Methods Patients with definitely diagnosed TIA consecutively included in Nanjing Stroke Registration System from September 2011 to December 2012 were classified into anterior and posterior circulation TIAs .Various risk factors were collected and a 90-day follow-up was conduc-ted.The ABCD2 score was obtained from each patient and its predictive value assessed using the receiver operating characteristic curve. Results A total of 204 patients were analyzed in the study , including 59 (28.9%) females, 143 with anterior and 61 with posterior circulation TIA, aged 63.7 ±11.2 years.There were no statistically significant differences in the incidence rate of stroke within 90 days between the anterior and posterior circulation TIAs (11.2% vs 9.8%, P=0.776).The mean ABCD2 score was re-markably higher in the anterior than in the posterior circulation TIA (3.7 ±1.5 vs 2.5 ±1.3, P<0.001).The area under the curve (AUC) in predicting stroke risk was 0.711 for the former (95%CI:0.575-0.847, P=0.006) and 0.555 for the latter (0.298-0.820, P=0.637). Conclusion The ABCD2 score can predict early stroke risk in anterior but not in posterior circulation TIA .
