Background: Knowing which areas of the brain are most vulnerable to acute ischemic stroke can focus care on more effective, targeted therapies. By displaying lesion incidence, these susceptible regions are clearly illustrated and can be correlated with characteristics common to that population. While previous studies created DWI lesion atlases, we aimed to map the spatio-temporal topology of multi-modal MRI sequences from a large cohort of stroke patients onto a standard atlas coordinate system. Methods: Pre-treatment ADC and perfusion-weighted imaging (PWI) and post-treatment FLAIR MRI sequences for 241 acute ischemic stroke patients which were retrospectively processed. Lesion locations were circumscribed semi-automatically on the ADC and FLAIR images. Perfusion parameters were extracted from the PWI images using Bayesian hemodynamic parameter estimation. To account for anatomical variation, custom software was created to co-register the MRIs onto an atlas. Decomposing by NIHSS score items, the software then created probabilistic maps by overlaying and averaging the subgroup’s lesions and parameters within the atlas. Results: An multi-dimensional set of annotated, co-registered stroke images for ADC, PWI and FLAIR sequences was established. Incidence maps based on NIHSS score items displayed anatomic localization of presenting symptoms in various imaging modes, before and after reperfusion or other therapies (Figure). A software suite was produced that co-registers, atlases, and calculates incidence maps for any set of images. Conclusions: A framework to obtain spatial incidence maps was applied to ADC, PWI and FLAIR MRI of ischemic stroke. This instrument can co-register any annotated imaging parameters and compute lesion maps for any metric of interest. This novel atlasing method may be used to elucidate stroke etiology, predict lesion progression and identify optimal treatments based on individual imaging features at presentation.

Background: Stroke in cancer patients is not rare, but is a devastating event with high mortality. However, the predictors of mortality in stroke patients with cancer have not been well addressed. D-dimer could be a useful predictor because it can reflect both thromboembolic events and advanced stages of cancer. In this study, we evaluate the possibility of D-dimer as a predictor of 30-day mortality in stroke patients with active cancer. Methods: We included 210 ischemic stroke patients with active cancer. The data of 30-day mortality were collected by reviewing medical records. We also collected follow-up D-dimer levels in 106 (50%) participants to evaluate the effects of treatment response on D-dimer levels. Results: Of the 210 participants, 30-day mortality occurred in 28 (13%) patients. Higher initial NIHSS score, D-dimer levels, CRP levels, frequent cryptogenic mechanism, systemic metastasis, multiple vascular territory lesion, hemorrhagic transformation, and larger infarct volume were related to 30-day mortality. In the multivariate analysis, D-dimer [adjusted OR (aOR) = 2.19; 95% CI, 1.46-3.28, P < 0.001] predicted 30-day mortality after adjusting for confounders. Initial NIHSS score (aOR = 1.07; 95% CI, 1.00-1.14, P = 0.043) and hemorrhagic transformation (aOR = 3.02; 95% CI, 1.10-8.29, P = 0.032) were also significant independently from D-dimer levels. In the analysis of D-dimer changes after treatment, the mortality group showed no significant decrease of D-dimer levels, despite treatment, while the survivor group showed opposite responses. Conclusions: D-dimer levels may predict 30-day mortality in acute ischemic stroke patients with active cancer.

Procedural Time

Background: Recent single center studies have suggested that “procedural time” independent of “time to procedure” can affect outcomes of acute ischemic stroke patients undergoing endovascular treatment (ET). We performed a pooled analysis from three ET trials to determine the effect of procedural time on angiographic and clinical outcomes. Objective: To determine the relationship between procedural time and clinical outcomes among acute ischemic stroke patients undergoing successful recanalization with ET. Methods: We analyzed data from SWIFT, STAR and SWIFT PRIME trials. Baseline demographic and clinical characteristics, NIHSS score on admission, intracranial hemorrhage rates and mRS at 3 months post procedure were analyzed. TICI scale was used to grade post procedure angiographic recanalization. Procedural time was defined by the time interval between groin puncture and recanalization. We estimated the procedural time after which favorable clinical outcome was unlikely even after recanalization (futile) after age and NIHSS score adjustment. Results: We analyzed 301 patients who underwent ET and had near complete or complete recanalization (TICI 2b or 3). The procedural time (±SD) was significantly shorter in patients who achieved a favorable outcome (mRS 0-2) compared with those who did not achieve favorable outcome (44±25 vs 51±33 minutes, p=0.04). Table 1. In the multivariate analysis (including all baseline characteristics with a p value <0.05 as independent variables), shorter procedural time was a significant predictor of lower odds of unfavorable outcome (OR 0.49, 95% CI 0.28, 0.85, p=0.012). The rates of favorable outcomes were significantly higher when the procedural time was <60 minutes compared with ≥60 minutes (62% vs 45%, p=0.020). Conclusion: Procedural time in patients undergoing mechanical thrombectomy for acute ischemic stroke is an important determinant of favorable outcomes in those with near complete or complete recanalization.

Abstract Background: Venous thromboembolism (VTE) prophylaxis with low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) is recommended in acute ischemic stroke patients, but most studies comparing LMWH and UFH are limited in methodology or sample size. The PREVAIL study was designed to assess the superiority of enoxaparin over UFH for VTE prophylaxis in acute ischemic stroke patients and to evaluate efficacy and safety according to stroke severity. Methods: Patients with acute ischemic stroke, confirmed by CT scan, and unable to walk unassisted due to motor impairment of the leg were enrolled in this prospective, open-label, parallel group, multicenter study. Patients from 15 countries were randomized within 48 h of stroke symptoms to receive enoxaparin 40 mg SC qd or UFH 5000 IU SC q12h for 10±4 days. Patients were stratified by NIH Stroke Scale score (NIHSS; severe ≥14, less severe &lt;14). The primary efficacy endpoint was the composite of symptomatic or asymptomatic deep-vein thrombosis (DVT), symptomatic pulmonary embolism (PE), or fatal PE during treatment. DVT was confirmed primarily by venography, or ultrasonography when venography was not practical. PE was confirmed by VQ or CT scan, or angiography. Primary safety endpoints included clinically significant intracranial and major extracranial bleeding. Results: 1762 acute ischemic stroke patients were randomized. Characteristics were similar between groups; mean age was 66.0±12.9 yrs, mean NIHSS score was 11.3. In the efficacy population, enoxaparin (n=666) and UFH (n=669) were given for a mean of 10.5±3.2 days. Enoxaparin resulted in a 43% relative reduction in the risk of the primary efficacy endpoint compared with UFH (10.2% vs 18.1%; RR 0.57; 95% CI 0.44–0.76; p=0.0001, adjusted for NIHSS score). Incidences of VTE events are shown in Table 1. Reductions in the primary endpoint remained significant in patients with a NIHSS score ≥14 (16.3% vs 29.7%, p=0.0036) and &lt;14 (8.3% vs 14.0%, p=0.0043). The composite of clinically significant intracranial and major extracranial bleeding was low and not significantly different between groups (Table 1). Conclusion: Enoxaparin 40 mg qd is superior to UFH q12h for reducing the risk of VTE in acute ischemic stroke patients, with no significant difference in clinically relevant bleeding. The reduction in VTE risk was consistent in patients with a NIHSS score ≥14 or &lt;14.

Definition Of

Background: Thrombolysis is often withheld from acute ischemic stroke patients presenting with mild symptoms; however, up to 40% of these patients end up with a poor outcome when left untreated. Since there is lack of consensus on the definition of minor symptoms, we aimed at addressing this issue by looking for features that would better predict functional outcomes at 3 months. Methods: Among all acute ischemic stroke patients admitted to our Stroke Unit (n = 1,229), we selected a cohort of patients who arrived within 24 hours from symptoms onset, with baseline NIHSS ≤6, not treated with thrombolysis (n = 304). Epidemiological data, comorbidities, radiological features and clinical presentation (NIHSS items) were collected to identify predictors of outcome. Our cohort was tested against minor stroke definitions selected from the literature and a newly proposed one. Results: Three months after stroke onset, 97 patients (31.9%) had mRS ≥2. Independent predictors of poor outcome were age (OR 0.97 [95% CI 0.95-9.99]) and baseline NIHSS score (OR 0.79 [95% CI 0.67-0.94]), while cardioembolic aetiology was negatively associated (OR 3.29 [95% CI 1.51-7.14]). Items of NIHSS associated with poor outcome were impairment of right motor arm (OR 0.49 [95% CI 0.27-0.91]) or the involvement of any of the motor items (OR 0.69 [95% CI 0.48-0.99]). The definition of minor stroke as NIHSS ≤3 and the new proposed definition had the highest sensitivity and accuracy and were independent predictors of outcome. Conclusions: Our study confirmed that in spite of a low NIHSS score, one third of patients had poor outcome. As already described, age and NIHSS score remained independent predictors of poor outcome even in mild stroke. Also, motor impairment appeared a major determinant of poor outcome. The new proposed definition of minor stroke featured the NIHSS score and the NIHSS items that better predicted functional outcome. Awareness that even minor stroke can yield to poor outcome should sensitize patients to arrive early to the ED and neurologists to administer rt-PA.

Abstract Background: Deep vein thrombosis (DVT) is an important complication of ischemic stroke, although the incidence of DVT is regarded as being lower in Asian than in non-Asian patients. Here, we investigated the incidence and factors associated with DVT in Asian patients with ischemic stroke.Methods: Acute ischemic stroke patients received lower extremity ultrasonography (LEUS) to diagnose the presence of DVT. Clinical characteristics and laboratory results, including D-dimer level, were compared between patients with and without DVT. Independent risk factors for DVT were investigated using multivariable analysis. Similar analysis was performed to identify factors associated with elevated D-dimer level (>0.5 mg/dl) in acute ischemic stroke patients.Results: During the study period, 289 patients were enrolled, and 38 (13.1%) showed DVT. Female sex (OR=2.579, 95% CI=1.224–5.432; p=0.013) and a high National Institutes of Health Stroke Scale (NIHSS) score (OR=1.191 95% CI=1.095–1.294; p=0.005) were independently associated with the presence of DVT, although D-dimer level was not. Stroke mechanism, especially cardioembolic stroke (OR=3.777, 95% CI=1.532–9.313; p=0.004; reference: large artery atherosclerosis), NIHSS score (OR=1.087, 95% CI=1.002–1.179; p=0.001) and thrombolysis (OR=12.360, 95% CI 2.456-62.213; p=0.002) were independently associated with elevated abnormal D-dimer levels.Conclusion: The severity of ischemic stroke, but not the D-dimer level, was associated with the presence of DVT in Asian ischemic stroke patients. D-dimer level was influenced by the stroke mechanism. LEUS in patients with severe neurological deficit, rather than screening with D-dimer, may be more beneficial for diagnosing DVT in Asian patients with acute ischemic stroke.

Background: Atrial fibrillation (AF) is the most common cardiac rhythm disorder associated with stroke. Increased risk of stroke is the same regardless of whether the AF is permanent or paroxysmal. However, detecting paroxysmal AF is challenging and resource intensive. We aimed to develop a predictive model for AF in patients with acute ischemic stroke, which could improve the detection rate of paroxysmal AF. Methods: We analyzed 10,034 adult patients with acute ischemic stroke. Differences in clinical characteristics between the patients with and without AF were analyzed in order to develop a predictive model of AF. The associated factors for AF were analyzed using multivariate logistic regression and classification and regression tree (CART) analyses. We used another dataset, which enrolled 860 acute ischemic stroke patients without AF at baseline, to test whether the developed model could improve the detection rate of paroxysmal AF. Among the study population, 1,658 patients (16.5%) had AF. Results: Multivariate logistic regression revealed that sex, age, body weight, hypertension, diabetes mellitus, hyperlipidemia, pulse rate at admission, respiratory rate at admission, systolic blood pressure at admission, diastolic blood pressure at admission, National Institute of Health Stroke Scale (NIHSS) score at admission, total cholesterol level, triglyceride level, aspartate transaminase level, and sodium level were major factors associated with AF. CART analysis identified NIHSS score at admission, age, triglyceride level, and aspartate transaminase level as important factors for AF to classify the patients into subgroups. Conclusions: When selecting the high-risk group of patients (with an NIHSS score >12 and age >64.5 years, or with an NIHSS score ≤12, age >71.5 years, and triglyceride level ≤61.5 mg/dL) according to the CART model, the detection rate of paroxysmal AF was approximately double in the acute ischemic stroke patients without AF at baseline.

Background: Use of IV tPA has increased over time, as has the adherence to the NQF endorsed performance measure for receipt of IV tPA within 3 hours. Little is known about trends in the reasons for patient ineligibility for IV tPA. This study examines trends in reasons for not providing IV tPA over time and by race and gender among acute ischemic stroke patients in the Paul Coverdell National Acute Stroke Registry (PCNASR), a quality improvement program for acute stroke implemented by state health departments. Methods: There were 13,164 PCNASR patients enrolled from 2008- 2010 with a clinical diagnosis of acute ischemic stroke with documentation of LKW and who arrived within 2 hours of LKW. Cochran-Armitage tests were used to test for trend on accepted reasons for not providing IV tPA within 3 hours of time last known well (LKW). Chi-square tests were used to test for differences among reasons between men and women and between non-Hispanic whites and minorities. Multiple reasons for not giving tPA could be selected. Results: Among 13,164 acute ischemic patients admitted between 2008 and 2010 with documentation of LKW and who arrived within 2 hours of LKW, 3781 (28.7%) received IV tPA, 7284 (55.3%) had documented reasons for not receiving IV tPA, and 2099 (16.0%) did not receive IV tPA. Contraindications to IV tPA, advanced age, rapid improvement and inability to determine eligibility increased over time. Mild stroke decreased over time. Conditions with warning, advanced age, limited life expectancy and family refusal were more common in women; mild stroke and rapid improvement were more common in men. Contraindications were more common in minorities; advanced age, mild stroke and rapid improvement, and family refusal were more common in non-Hispanic whites. When advanced age was selected, 46.6% of patients were over age 90 and 3.4% were under age 80. When stroke too mild was selected, 44.8% of patients had missing NIHSS scores, 42.1% of scores were 0-4, 8.8% were 5-9, and 4.3% were ≥ 10. The three most common reasons for not providing tPA were rapid improvement (40.9%), mild stroke (33.0%), and contraindications (29.2%) in 2010. Conclusions: More than half of ischemic stroke patients arriving within 2 hours of LKW were ineligible to receive IV tPA. There was little use of advanced age for patients under age 80. Documentation of stroke too mild was not substantiated by an NIHSS score in nearly half of patients. Better documentation of NIHSS score should be provided.

Background & Purpose: Studies have shown that patients who do not receive IV t-PA due to mild and rapidly improving stroke symptoms (MaRISS) are often not discharged home. The purpose of this study was to identify whether presenting symptoms and response to initial dysphagia screen can predict which patients not treated with IV tPA due to MaRISS have an unfavorable outcome. Methods: Acute ischemic stroke (AIS) patients presenting to hospitals participating in the Georgia Coverdell Acute Stroke Registry and not treated with IV t-PA due to MaRISS alone from January 1, 2009 through December 31, 2013 were included in this analysis. Patients who were unable to ambulate or needed assistance to ambulate prior to admission were excluded. Presenting symptoms and response to dysphagia screen were collected from retrospective chart review at participating hospitals. Multivariable regression analysis was used to identify factors associated with a lower likelihood of favorable outcome, defined as discharge to home. During the study period, < 1% of patients presenting to participating hospitals with MaRISS within the 3 hour time window received IV t-PA. Results: Of 841 AIS patients who did not receive IV-tPA due to MaRISS [median NIHSS 1 (Q1-Q3: 0-3)], 160 (19%) did not have a favorable outcome. Factors associated with lower likelihood of a favorable outcome included increasing NIHSS score (per unit OR 0.89, 95% CI 0.84 to 0.93), weakness as the presenting symptom (OR 0.50, 95% CI 0.30 to 0.84), and a failed dysphagia screen (OR 0.43, 95% CI 0.23 to 0.80). Conclusion: Nearly 1 in 5 AIS patients presenting with MaRISS were not discharged to home. Among AIS patients who present with MaRISS and do not receive IV thrombolytic therapy, baseline characteristics including increasing NIHSS score and weakness as a presenting symptom, and a failed dysphagia screen were all associated with a lower likelihood of discharge to home. Given the low rate of patients presenting during the study period, a prospective randomized trial to evaluate IV t-PA treatment focusing on this subgroup of patients is warranted.

Favorable Functional Outcome

Background and Purpose: Treatment with Selective Serotonin Reuptake Inhibitors (SSRIs) following acute ischemic stroke was shown to improve functional and motor recovery independently of depression, possibly mediated by long-term mechanisms such as increased brain plasticity. In animal studies, chronic SSRI treatment is superior over short-term SSRI in evoking neurogenesis but the applicability of this observation to humans remains unelucidated. We hypothesized that pre-treatment with SSRI in acute ischemic stroke patients is associated with improved recovery compared to post-stroke SSRI. Subjects and Methods: We performed an exploratory analysis in consecutive acute ischemic stroke patients who were pre-treated or treated de novo either with fluoxetine, citalopram or escitalopram. Effects of SSRI-pre-treatment on short-term clinical (total NIHSS and NIHSS motor items) and functional (mRS) outcome at discharge compared to post-stroke SSRI were assessed using bivariate and multivariate analyses. Results: Of 2653 patients screened, 239 were included (aged 69±14 years, mean±SD; 42% men, baseline median NIHSS 7 [IQR, 10]). Compared to post-stroke SSRI (n=188), in the SSRI pre-treatment group (n=51) favorable functional outcome at discharge (mRS≤2) was more frequent (41% vs. 20%; p=0.002), duration of hospitalization was shorter (median: 7 versus 11 days; p<0.0001), and there was a non-significant trend toward improved motor recovery (decrease in NIHSS motor items ≥2 points or 0-1 at discharge; 63% vs. 49%; p=0.08). However there was no such difference in total NIHSS recovery (≥4 points or 0-1 at discharge; p=n.s.). Pre-treatment with SSRI was an independent predictor of favorable functional outcome (mRS≤2) at discharge (OR: 4.00; 95%CI: 1.68-9.57; p=0.002) after adjusting for age, pre-stroke mRS, baseline NIHSS and IV-thrombolysis. Conclusions: Our data suggest that pre-treatment with SSRI may be linked to early clinical recovery after acute ischemic stroke and support the hypothesis that pre-stroke SSRI might be superior to post-stroke SSRI.

Background: Stroke is a serious public health issue and third leading cause of death worldwide. Hypoalbuminemia is commonly found factor in patients of stroke and is also associated with severe disease as well as pro inflammatory patterns of serum protein electrophoresis. Therefore, further research for understanding the role of Hypoalbuminemia in stroke is important to devise strategies for better management of stroke. Aim : To determine the frequency of hypoalbuminemia in acute ischemic stroke patients based on stroke severity. Methods: This descriptive cross- sectional study was conducted in Shifa International hospital stroke unit for 6 months from May 15, 2018 till Nov 15, 2018. Data was collected from 100 patients using purposive sampling. After taking consent from patient or attendant, the demographic data was collected on a structured proforma. Baseline serum albumin and stroke severity using the NIHSS score was also assessed. All data was entered and analysed using SPSS 21. After descriptive analysis, post stratified Chi Square test was applied for gender and age categories. Results: The mean age of patients was 63.60 ± 11.87 years with 57(57%) male and 43(43%) female cases. The mean serum albumin level was 4.03 ± 0.94 with minimum and maximum values as 1.50 and 5.5. Among cases with minor, moderately severe and with severe stroke, 6(37.5%) cases, 18(25.7%) cases and 6(42.9%) cases had Hypoalbuminemia. The frequency of hypoalbuminemia was statistically same with respect to severity of stroke, p-value > 0.05. Conclusion: This study concludes that the frequency of hypoalbuminemia in acute ischemic stroke patients was diagnosed in almost one third cases, however, no statistical association could be found. Hence, screening for hypoalbuminemia should be done for better management of stroke patients. Keywords: Storke, NIHSS score, serum albumin, hypoalbuminemia, mortality
