In 24 TIA patients, we investigated the following parameters in relation with stroke maturation: ABCD2 score, smoking habits, blood profile, HbA1C, dyslipidemia, coagulation factors, carotid echography, electrocardiography, cardiac echography, chest X-ray, neurological symptom/signs, imaging, and recurrence of neurological symptom on follow-up.
Patients with both multiple infarctions and ABCD2 ≥4 were associated with approximately 15.5-fold risk of stroke at 90 days (28.8% vs. 2.1%, HR =15.455, 95% confidence interval [CI], 7.946-30.057, p <0.001), compared with those with no infarction or ABCD2 <4.
Of the 35 identified studies on ABCD2 and ABCD3-I, 6 studies (7364 participants) directly compared the diagnostic accuracies of ABCD2 and ABCD3-I scores for occurrence of a future stroke.
