ABSTRACT

Background: Transient ischemic attacks (TIA) serve as warning signs of future stroke. The research aims to study the prognostic value of the ABCD2 score after short-term follow-up of patients with a transient ischemic attack and their risk of stroke development during the following (2, 7, 90) days. Results: This prospective observational study included (265) patients who had a transient ischemic attack and who They visited the emergency department at Tishreen University Hospital and their symptoms had not been present for more than 42 hours. The ABCD2 score was calculated for all patients and a brain scan or MRI was performed within 24 hours for all patients. The patients were followed up after (2-7-90) days to evaluate the incidence of New cerebrovascular accidents, the incidence of stroke was 3.4% after 2 days, 5.3% after 7 days, and 7.2% after 90 days of follow-up. The standard point with the highest sensitivity and specificity for predicting the occurrence of stroke was the ABCD2 value = 5, with a sensitivity of 73.3% and a specificity of 65.1% for prediction. With regard to stroke, with regard to the development of stroke, which was on the rise with increasing values of the ABCD2 index, as the low risk group (0-3) recorded 2.1%, and it rose to 10% in the medium risk group (4-5), and it rose to 67.5% in the high risk group. (6-7), and the mortality rate among the study patients was 1.5%, with 4 cases, as no deaths occurred in the low-risk group, while it was distributed between the two groups with medium risk, at a rate of 0.8%, and in the high-risk group, at a rate of 7.5%, with statistical significance (p -value: 0.005).
