presented with DWI lesions. These patients had higher National Institute of Health Stroke Scale and ABCD2 scores and presented more frequently with vessel occlusion and perfusion deficits, but had similar functional outcome at 3 months. Taken together, high-resolution DWI provides evidence of ischemic brain injury in the majority of TIA patients. ANN NEUROL 2019;86:452-457.© 2019 The Authors.

62. Is Transient Ischemic Attack a Medical Emergency? OHTAC Recommendation

, where patients can be evaluated and treated urgently, results in lower rates of stroke and disability than conventional treatment. About half of strokes following TIA occur within the first 48 hours; therefore, patients with TIA should be evaluated as early as possible within 24 hours of first call to medical attention. Patients at high risk of stroke may require admission to a stroke unit for further evaluation and appropriate treatment. This review showed that patients with an ABCD2 score of 4 (...) or higher have significantly higher rates of stroke or recurrent TIA if they receive standard treatment and are discharged from an ED, compared to patients who are hospitalized. This may indicate that higher-risk patients need more comprehensive, intensive investigation and management than lower-risk patients. At the same time, this analysis identified limitations to the use of ABCD2 risk scores in assessing which patients are at higher risk of stroke. ABCD2 risk scores do not reflect the absence

attributable to sodium intake >2.0 g/d, representing nearly 1 in 10 (9.5%) of all CVD deaths. Between 2003 and 2012, certain aspects of diet quality improved in the United States, including increases in whole grains and reductions in sugar-sweetened beverages. The prevalence of both children and adults meeting the dietary goals improved between 2003 to 2004 and 2011 to 2012. The prevalence of ideal levels of diet (healthy diet score >80) increased from 0.2% to 0.6% in children and from 0.7% to 1.5 (...) % in adults. During this period, the proportion of youths aged 5 to 19 years with poor scores on the dietary metric for cardiovascular health decreased steadily from 69.2% to 54.6%, whereas for adults, the decrease was from 50.3% to 41.0%. Although healthier diets cost modestly more than unhealthful diets, comparing extremes of unhealthful versus healthful food-based diet patterns, the more healthful patterns cost on average ≈$1.50 per day more. Similarly priced options are also common; in a comparison

64. Reducing time-to-unit among patients referred to an outpatient stroke assessment unit with a novel triage process: a prospective cohort study. (PubMed)

for effective triage as medical intervention for true TIA/minor stroke is time-sensitive and TIA unit spots are a finite resource.Prospective cohort study design utilizing patient referral data and TIA unit arrival times from a regional fast-track TIA unit on Vancouver Island, Canada, accepting referrals from emergency departments (ED) and general practice (GP). Historical referral cohort (N = 2942) from May 2013-Oct 2014 was triaged using the ABCD2 score; prospective referral cohort (N = 2929) from Nov (...) 2014-Apr 2016 was triaged using the novel system. A retrospective survival curve analysis, censored at 28 days to unit arrival, was used to compare days to unit arrival from event date between cohort patients matched by low (0-3), moderate (4-5) and high (6-7) ABCD2 scores.Survival curve analysis indicated that using the novel triage system, prospectively referred TIA/minor stroke patients with low and moderate ABCD2 scores arrived at the unit 2 and 1 day earlier than matched historical patients

66. Antiplatelet vs R-tPA for Acute Mild Ischemic Stroke

with alteplase for acute ischemic stroke within 4.5 hours from stroke onset. Minor stroke is usually defined as NIHSS score ≤ 3 or 5,although it accounts for 1/2-2/3 of AIS, the evidence of thrombolysis is insufficient. A study from Canada shows that 28.5% of patients with minor stroke who have not receive rt-pa thrombolytic therapy are unable to walk independently when discharged. Based on such a consideration,the PRISMS study further compares the efficacy and safety of thrombolytic therapy (...) even if the patient's condition has worsened, is clinically more puzzling. The CHANCE study in 2013 shows that the efficacy of aspirin with clopidogrel is superior to aspirin alone with minor stroke (NIHSS < 3) or TIA(ABCD2 < 4). The POINT study in 2018 further confirmed the efficacy and safety of intensive antithrombotic therapy within 12 hours of onset with minor stroke. Based on the above discussion, this study aims to explore the efficacy and safety of aspirin with clopidogrel vs alteplase

Evaluation was initiated within 12 h among 201 (57%) patients. After logistic regression, OBP referral was by comparison with ED the only independent factor associated with an evaluation delay >12 h (OR 5.7, 95% CI: 3.5-9.3, p < 0.0001). Conclusion: Our results suggest that preliminary assessment by OBP may increase the delay

72. Uncertainty as a Key Influence in the Decision To Admit Patients with Transient Ischemic Attack. (PubMed)

administrative data to identify admission rates and chart review data to identify ABCD2 scores (a tool to classify stroke risk after TIA).Providers' decisions to admit TIA patients were related to uncertainty in several domains: lack of a facility TIA-specific policy, inconsistent use of ABCD2 score, and concerns about facilities' ability to complete a timely workup. There was a disconnect between staff perceptions about TIA admission and facility admission rates. According to chart review data, staff (...) at facilities with higher admission rates in FY 2011 reported consistent reliance on ABCD2 scores and related guidelines in admission decision-making.Many factors contributed to decisions regarding admitting a patient with TIA; however, clinicians' uncertainty appeared to be a key driver. Further quality improvement interventions for TIA care should focus on facility adoption of TIA protocols to address uncertainty in TIA admission decision-making and to standardize timely evaluation of TIA patients

80. Coated-platelets predict stroke at 30 days following TIA. (PubMed)

Coated-platelets predict stroke at 30 days following TIA. To examine the potential for coated-platelets, a subset of highly procoagulant platelets observed on dual agonist stimulation with collagen and thrombin, for predicting stroke at 30 days in patients with TIA.Consecutive patients with TIA were enrolled and followed up prospectively. ABCD2 scores were obtained for each patient. Coated-platelet levels, reported as percent of cells converted to coated-platelets, were determined at baseline (...) value of 0.16 (95% CI 0.06-0.26), and negative predictive value of 0.98 (95% CI 0.96-1.0). The adjusted hazard ratio of incident stroke in patients with coated-platelet levels ≥51.1% was 10.72 compared to those with levels <51.1%. ROC analysis showed significant improvement in the predictive ability of the coated-platelet model compared to ABCD2 score (AUC 0.78 ± 0.07 vs 0.54 ± 0.07, p = 0.01).These findings suggest a role for coated-platelets in risk stratification for stroke at 30 days after TIA.©
