ABCD3-I and ABCD2 Scores in a TIA Population with Low Stroke Risk.

Objectives: We aimed to evaluate the ABCD3-I score and compare it with the ABCD2 score in short- (1 week) and long-term (3 months; 1 year) stroke risk prediction in our post-TIA stroke risk study, MIDNOR TIA.

Materials And Methods: We performed a prospective, multicenter study in Central Norway from 2012 to 2015, enrolling 577 patients with TIA. In a subset of patients with complete data for both scores ( = 305), we calculated the AUC statistics of the ABCD3-I score and compared this with the ABCD2 score.

Stroke risk after transient ischemic attack in a Norwegian prospective cohort.

Background: Transient ischemic attack (TIA) is a risk factor of stroke. Modern treatment regimens and changing risk factors in the population justify new estimates of stroke risk after TIA, and evaluation of the recommended ABCD stroke risk score.

Methods: From October, 2012, to July, 2014, we performed a prospective, multicenter study in Central Norway, enrolling patients with a TIA within the previous 2 weeks.
