Patient demographics (age and sex), vascular risk factors, TIA symptom details, and ABCD2 score were collected by reviewing medical records.
The ABCD2 score combines five clinical variables (age, blood pressure, clinical features, duration of symptoms, and history of diabetes mellitus) into a seven-point scale.
Population-based study of ABCD2 score, carotid stenosis, and atrial fibrillation for early stroke prediction after transient ischemic attack: the North Dublin TIA study.
ABCD3 and ABCD3-I scores are superior to ABCD2 score in the prediction of short- and long-term risks of stroke after transient ischemic attack.
Only 14 (5 percent) were readmitted to our institution within 90 days with further TIA and stroke, and this recurrent stroke risk correlated very strongly with a higher ABCD2 score of 6-7 (p=0.001).
* First, it could be used to calculate the ABCD2 score and quantify future stroke risk to present to the patient.
Sensitivity and specificity of each ABCD2 score for 3rd day stroke risk was calculated.
The ABCD2 score uses clinical features, medical history, and blood pressure to generate a number that can be used to determine the patient's short-term risk of stroke.5
Johnston and others have established that roughly 34% of TIA patients have an ABCD2 score of 0-3, putting them in a low short-term risk category, with an associated 1% risk of stroke within the first 2 days after their TIA.
A young person who is an IV drug user and has a 1-minute spell of diplopia is someone you'd worry about, and yet that person probably has an ABCD2 score of 0," Dr.
He and his coworkers developed the ABCD2 score
through analysis of large patient data sets (Lancet 2007;369:283-92).
If patients agree, they answer a 26-item questionnaire that incorporates the ABCD2 score
, as well as questions that give some hint about the brain territory affected.
