Significant risk factors for stroke were: age, previous TIA, atrial fibrillation (AF), oral anticoagulant (OAC) treatment, hypertension treatment, and the ABCD2 items speech impairment, unilateral weakness, and diabetes mellitus. Of the unique patients, 545 had one or more strokes (3.9%), corresponding to 34 events per 1,000 person years. The mortality for all TIA patients during the follow-up time was 7.1%. ![]() The follow-up time varied between 0 and 819 days, with an average of 417 days. The predictive value of the ABCD2 score was assessed by calculating the area under the receiver operating characteristics curve.Ī total of 15,068 TIA episodes occurred in 14,102 patients. Cox's regression was used for risk evaluation. Stroke occurrence was monitored via Riksstroke. Data from Riksstroke's TIA module, and the national cause-of-death register, for the years 20 were used in this study. ![]() Riksstroke is the national stroke registry in Sweden. ![]() ![]() We also wanted to assess the predictive value of the ABCD2 score in this context. The purpose of this study was to investigate the other stroke risks in the longer term, after the implementation of a more active approach to TIA. Almost 10 years ago, the results of the EXPRESS and SOS-TIA studies called for a more rapid management of TIA patients. In the absence of active management, the stroke risk after a transient ischemic attack (TIA) may be high.
