Abstract：Objective To study the value of ABCD3‐I score in predicting the recurrent risk of early ischemic stroke following transient ischemic attack (TIA) .Methods One hundred and sixty‐two TIA patients were divided into low recurrent risk group (n=24) ,moderate recurrent risk group (n=97) and high recurrent risk group (n= 41) according to their ABCD3‐I score .The patients were followed up for 90 days during which the incidence of recurrent ischemic stroke was ob‐served .T he values of ABCD2 ,ABCD3‐I and ESRS score in predicting the recurrent risk of early is‐chemic stroke were assessed by measuring the area under the ROC curve .Results Ischemic stroke reoccurred in 13 (8 .0% ) out of the 162 patients on day 7 after TIA and in 26 (16 .0% ) out of the 162 patients during the 90‐day follow‐up period .T he incidence of recurrent ischemic stroke was significantly higher in moderate and high recurrent risk groups than in low recurrent risk group during the 90‐day follow‐up period (14 .4% vs 0% ,P=0 .037 ,29 .3% vs 0% ,P=0 .002) . The area under the ROC curve of ABCD3‐I was 0 .73 on day 7 after TIA (95% CI:0 .62 -0 .82) and was 0 .71 during the 90‐day follow‐up period (95% CI:0 .60 -0 .79) ,which were higher than that of ABCD2 and ESRS score in predicting the recurrent risk of early ischemic stroke .Conclusion The value of ABCD3‐I score is higher than that of ABCD2 and ESRS score in predicting the re‐current risk of early ischemic stroke following TIA .
