121. Diagnostic Usefulness of the ABCD2 Score to Distinguish Transient Ischemic Attack and Minor Ischemic Stroke From Noncerebrovascular Events. The North Dublin TIA Study. Full Text available with Trip Pro

Diagnostic Usefulness of the ABCD2 Score to Distinguish Transient Ischemic Attack and Minor Ischemic Stroke From Noncerebrovascular Events. The North Dublin TIA Study. Transient ischemic attack (TIA) diagnosis is frequently difficult in clinical practice. Noncerebrovascular symptoms are often misclassified as TIA by nonspecialist physicians. Clinical prediction rules such as ABCD(2) improve the identification of patients with TIA at high risk of early stroke. We hypothesized that the ABCD(2 (...) ) score may partly improve risk stratification due to improved discrimination of true TIA and minor ischemic stroke (MIS) from noncerebrovascular events.Consecutive patients with TIA were identified within a prospective population-based cohort study of stroke and TIA. The cohort was expanded by inclusion of patients with MIS and noncerebrovascular events referred to a daily TIA clinic serving the population. Diagnosis was assigned by a trained stroke physician independent of ABCD(2) score.Five hundred

122. Can the ABCD2 Risk Score Predict Positive Diagnostic Testing for Emergency Department Patients Admitted for Transient Ischemic Attack? Full Text available with Trip Pro

Can the ABCD2 Risk Score Predict Positive Diagnostic Testing for Emergency Department Patients Admitted for Transient Ischemic Attack? We sought to determine if the ABCD2 score, typically used for risk stratification, could predict having a positive diagnostic test in patients evaluated acutely for transient ischemic attack.We performed a retrospective cohort study for patients admitted from our emergency department with a new diagnosis of transient ischemic attack confirmed by a neurologist (...) . ABCD2 scores were calculated and patients with a score of > or = 4 were placed in the high-risk cohort. Tests evaluated included electrocardiogram, CT, MRI, MR angiography, carotid ultrasonography, and echocardiography. Specific test findings considered to signify positive diagnostic tests were created a priori.We identified 256 patients with transient ischemic attack for inclusion; 167 (61%) were female, the median age was 60 years (interquartile range, 50 to 72), and 162 (63%) patients had

123. The California, ABCD, and Unified ABCD2 Risk Scores and the Presence of Acute Ischemic Lesions on Diffusion-Weighted Imaging in TIA Patients. Full Text available with Trip Pro

The California, ABCD, and Unified ABCD2 Risk Scores and the Presence of Acute Ischemic Lesions on Diffusion-Weighted Imaging in TIA Patients. Some clinical models, like California ABCD and unified ABCD2 scores, are now available to predict the early risk of stroke after a TIA. Despite the transitivity of symptoms, DWI identified an area of acute brain ischemia in almost half of patients. It would be interesting to know how the presence of DWI abnormalities relates to clinical risk scores (...) to plan other prognostic variables or to recommend the performance of DWI.We prospectively studied 135 consecutive TIA patients visited by the neurologists in our institution. All patients underwent DWI (3.8+/-1.7 days after symptoms onset). Clinical risk scores (California, ABCD, and ABCD2) were calculated prospectively for each patient. The identification of acute ischemic lesions (positive DWI) was related to the presence of clinical features and clinical risk scores.DWI were positive in 67 (49.6

124. ABCD2 Scores and Prediction of Noncerebrovascular Diagnoses in an Outpatient Population. A Case-Control Study. Full Text available with Trip Pro

ABCD2 Scores and Prediction of Noncerebrovascular Diagnoses in an Outpatient Population. A Case-Control Study. Among patients with transient ischemic attack, the ABCD2 score predicts short-term stroke risk. Use of the ABCD2 score assumes the underlying diagnosis to be transient ischemic attack; however, most transient ischemic attack services assess a variety of diagnoses. We hypothesized that patients with low ABCD2 score predominantly have noncerebrovascular diagnoses.Our transient ischemic (...) attack clinics assess all suspected cerebrovascular events referred. Comprehensive clinical and investigation details are prospectively recorded. We collated data for patients seen between August 1992 and January 2005 inclusive. We calculated ABCD2 scores and compared proportions of noncerebrovascular diagnoses for each ABCD2 grade using chi(2) analysis. We ran similar analyses for atrial fibrillation, vascular lesions on brain imaging, and carotid stenosis. We calculated positive predictive value

of stroke after a TIA were the California and ABCD scores. Both scores are based on clinical factors with several key elements in common. However, neither scoring system was devised to predict stroke within 48 hours of TIA, a time period which may be most clinically relevant. In this study[1] published in the Lancet in January, the creators of the California and ABCD scores tested a new system, called the ABCD2 score. In this scoring system, patients receive points for five factors including: age (...) and primary care clinics in California and Oxford. It was found to be a more accurate predictor of stroke than either the California or the ABCD scores. The 2 day risk of stroke after TIA was 0% for patients with an ABCD2 score of 0-1, 1-2% for a score of 2, 0-3% for a score of 3, 2-5% for a score of 4, 3-7% for a score of 5, 4-14% for a score of 6, and 0-50% for a score of 7. Stroke risk at 7 and 90 days was also studied and was found to be higher in patients with higher ABCD2 scores. Based

126. Prognosis in patients with transient ischaemic attack (TIA) and minor stroke attending TIA services in the North West of England: the NORTHSTAR Study Full Text available with Trip Pro

Prognosis in patients with transient ischaemic attack (TIA) and minor stroke attending TIA services in the North West of England: the NORTHSTAR Study The ABCD2 score predicts stroke risk within a few days of transient ischaemic attack (TIA). It is not clear whether the predictive value of the ABCD2 score can be generalised to UK TIA services, where delayed presentation of TIA and minor stroke are common. We investigated prognosis, and the use of the ABCD2 score, in patients attending TIA (...) 30 incident strokes. At least one incident TIA occurred in 100 patients (14%), but only four had a subsequent stroke. In multifactorial analyses, the ABCD2 score was unrelated to the risk of the primary outcome, but predicted the risk of incident stroke: score 4-5: hazard ratio (HR) 3.4 (95% CI 1.0 to 12); score 6-7: HR 4.8 (1.3 to 18). Of the components of the ABCD2 score, unilateral motor weakness predicted both the primary outcome (HR 1.8 (1.2 to 2.8)) and stroke risk (HR 4.2 (1.3 to 14

131. Higher ABCD2 Score Predicts Patients Most Likely to Have True Transient Ischemic Attack. Full Text available with Trip Pro

Higher ABCD2 Score Predicts Patients Most Likely to Have True Transient Ischemic Attack. Some patients diagnosed with transient ischemic attack (TIA) in the emergency department may actually have alternative diagnoses such as seizure, migraine, or other nonvascular spells. The ABCD2 score has been shown to predict subsequent risk of stroke in patients with TIA diagnosed by emergency physicians, but perhaps high ABCD2 scores simply separate those patients with true TIA from those (...) records analyst and determined whether the spell was likely to represent a true TIA. Subsequent strokes within 90 days were identified. ABCD2 scores were calculated for all patients and 2-sided Cochrane-Armitage trend tests were used to assess subsequent risk of stroke.Of the 713 patients reviewed by the expert neurologist, 642 (90%) were judged to likely have experienced a true TIA. Ninety-day stroke risk was 24% (95% CI, 20% to 27%) in the group judged to have experienced a true TIA and 1.4% (0
