The ABCD2 score is routinely used in assessment of transient ischaemic attack (TIA) to assess the risk of developing stroke. There remains uncertainty regarding whether the ABCD2 score could be used to help predict extent of carotid artery stenosis (CAS). 
How useful is the ABCD 2 TIA score in predicting and preventing stroke ? ¿
Background and objectives: Independent validations of the ABCD2 score used to predict stroke development have reported conflicting results, and besides expert opinion as to proper diagnostic approachExpand
Prevalence and risk factors of symptomatic carotid stenosis in patients with recent transient ischaemic attack or ischaemic stroke in the Netherlands
TLDR
It was found that higher age, male sex, White ethnicity, retinal ischaemia and current smoking were important risk factors for symptomatic internal carotid artery stenosis. Expand
Visualisation of Integrated Patient-Centric Data as Pathways: Enhancing Electronic Medical Records in Clinical Practice
TLDR
A methodology to integrate patient-centric data from different EMR systems into clinical pathways that represent the history of all patient interactions with the hospital during the course of a disease and beyond is created. Expand

Performance of the ABCD and ABCD2 Scores in TIA Patients with Carotid Stenosis and Atrial Fibrillation
TLDR
The ABCD and ABCD2 risk scores appear to identify patients with ≧50% carotid stenosis or AF who are at high risk of stroke, and these findings should be interpreted with caution due to the small number of outcomes among these subgroups. Expand
Correlation of ABCD2 score with degree of internal carotid artery stenosis: an observational pilot study.
TLDR
Because no correlation between ABCD2 scores and the degree of ICA stenosis was found, all patients with carotid territory TIA should undergo urgent imaging of theCarotid arteries because a high proportion of these patients may benefit from RACE. Expand
A simple score (ABCD) to identify individuals at high early risk of stroke after transient ischaemic attack
TLDR
Although further validations and refinements are needed, the ABCD score can be used in routine clinical practice to identify high-risk individuals who need emergency investigation and treatment. Expand
Population-Based Study of ABCD2 Score, Carotid Stenosis, and Atrial Fibrillation for Early Stroke Prediction After Transient Ischemic Attack: The North Dublin TIA Study
TLDR
The ABCD2 score had predictive utility in patients with TIA suspected by nonspecialists, and low scores occurred in several patients with stroke recurrences, suggesting that caution is needed before using the score in isolation. Expand
ABCD2 Score and Large-Artery Atherosclerosis
TLDR
Compared to patients in the low- risk ABCD2 scores, the patients with medium- to high-risk ABCD1 scores are more likely to have symptomatic and asymptomatic vascular stenotic lesions, however, 1 in 5 patients with low-riskABCD2 score has symptomatic stenosis, indicating ABCD 2 score does not identify all patients with symptomaticstenotic lesions.

Validation and refinement of scores to predict very early stroke risk after transient ischaemic attack
TLDR
Existing prognostic scores for stroke risk after TIA validate well on multiple independent cohorts, but the unified ABCD(2) score is likely to be most predictive. Expand
Triaging TIA/minor stroke patients using the ABCD2 score does not predict those with significant carotid disease.
TLDR
The ABCD(2) score was unable to identify TIA/minor stroke patients with a higher prevalence of clinically important ipsilateral carotid disease. Expand
Guidelines for the Primary Prevention of Stroke: A Statement for Healthcare Professionals From the American Heart Association/American Stroke Association
TLDR
Evidence-based recommendations are included for the control of risk factors, interventional approaches to atherosclerotic disease of the cervicocephalic circulation, and antithrombotic treatments for preventing thrombosis and thromboembolic stroke. Expand
Screening for carotid artery stenosis: U.S. Preventive Services Task Force recommendation statement.
TLDR
The U.S. Preventive Services Task Force examined the evidence on the natural history of CAS, systematic reviews of the accuracy of screening tests, observational studies of the harms of screening and treatment of asymptomatic CAS, and randomized, controlled trials of the benefits of treatment for CAS with carotid endarterectomy. Expand
Prognostic value of the ABCD² clinical prediction rule: a systematic review and meta-analysis.
TLDR
The ABCD² is a useful CPR, particularly in relation to 7-day risk of stroke, and there is a non-significant trend towards over-prediction of stroke in all risk categories at 90 days. Expand
