Stroke, Transient ischemic attack: ABCD score for predicting risk of evolving to stroke
DISEASE INTERVENTION COMPARISON RESULTS
Stroke. 2010 Apr;41(4):667-73 Systematic Review
IN stroke, ischemic, transient ischemic attack, risk of evolving to stroke The Use of
ABCD and ABCD2 modified scores: age, hypertension, clinical deficit, duration of symptoms (and diabetes)
As Prognostic Item

no comparison
To predict risk of stroke at 7 days: AUC 0.72 for both scores. However, predictive value varied significantly between studies

To identify patients at high-risk of having an stroke in the following 30 days: 0% risk if score < 3; 3.5% and 7.6% scores 3 and 4; 21% score = 5; 31% score = 6.

To identify patients at high-risk of having an stroke in the next 7 days: 0.4% risk if score < 5, 12% if = 5, 31% if = 6.
Stroke. 2010 May;41(5):844-50 Cohorts
IN stroke, ischemic, transient ischemic attack, risk of evolving to stroke The Use of
ABCD2 modified score (age, hypertension, clinical deficit, duration of symptoms and diabetes) or carotid stenosis
As Prognostic Item

no comparison
To accurately predict risk of stroke at 90 days in confirmed cases of TIA: 24% of patients with TIA recurrence or stroke had low ABCD2 scores. Presence and severity of carotid stenosis was more predictive.

ABCD2 modified score, in patients undergoing systematicaly central nervous system and carotid artery imaging
As Prognostic Item

To predict risk of stroke at 7 nor at 90 days: 2.1% in the low-risk group, 2.1% in the intermediate-risk group, and 3.6% in the high-risk group.

To discriminate between patients needing or not urgent treatment: 20% of patients with an score < 4 required consideration for emergency treatment, sensibility 62%

To identify patients at high-risk of having an stroke in the following 2 days: 1% risk if score 1-3; 4.1% score 4-5; 8.1% score 6-7. Also good stratification at 7 and 90 days.
