Background: Thromboelastography (TEG) provides an integrated measurement of blood coagulation function and has been reported to be a useful tool for predicting clinical outcomes in patients with cardiovascular diseases. We aimed to investigate the application of TEG on admission for predicting early neurological deterioration (END) in patients with acute ischemic stroke and its potential correlation with the evolution of ischemic lesions. Methods: Among patients consecutively admitted between January 1, 2016, and September 31, 2017, those presenting with mild and moderate acute ischemic stroke (National Institutes of Health Stroke Scale [NIHSS] score ≤14) within 24 h of stroke onset were identified and included in this study. TEG was performed on the first day of admission. END was defined as an increase of ≥1 on subitems of the NIHSS or the emergence of new symptoms within 72 h of admission. Demographics, lab test results, and TEG values were compared according to whether END occurred. A multiple logistic regression model was then developed to investigate the predictive power of TEG for END. Receiver operating characteristic (ROC) curves were then plotted to evaluate the optimal cutoff values. Results: Of the 246 eligible patients (mean age 65.3 ± 12.9 years, 73.6% male), END was identified in 72 (29.3%) patients. Patients with END corresponded to a higher proportion of females, a more prevalent history of diabetes mellitus (DM), higher baseline NIHSS scores, higher serum high-sensitivity C-reactive protein (hsCRP) levels, and significantly shorter R on TEG (4.0 ± 1.0 vs. 4.7 ± 1.2 min, p < 0.001). In further comparisons stratified by R tertiles, significant trends were found between shorter R and being female and older and being more likely to exhibit diffusion weighted imaging progression on follow-up MRI. After adjusting for female sex, baseline NIHSS score, DM, and hsCRP, the lower tertile of R (R ≤3.8 min) was strongly associated with END (OR 3.556, 95% CI 1.165–10.856, p < 0.001). ROC analysis demonstrated that R ≤3.45 min had the best predictive value for END with 87.9% sensitivity and 40.3% specificity. Conclusion: Decreased R time on admission TEG is associated with END within 3 days in patients with acute ischemic stroke.

Early Neurological Deterioration

Background and Aims. Metabolic syndrome (MetS) has been associated with occurrence and prognosis of ischemic stroke. This study aimed to evaluate whether an association exists between MetS and early neurological deterioration (END) following acute ischemic stroke and the possible role inflammatory biomarkers play.Methods and Results. We conducted a prospective cohort investigation that involved 208 stroke patients within 48 hours from symptom onset. MetS was determined by the modified National Cholesterol Education Program/Adult Treatment Panel III criteria. END was defined as an increase of⩾1 point in motor power or⩾2 points in the total National Institutes of Health Stroke Scale (NIHSS) score within 7 days. Univariate logistic regression analysis showed that patients with MetS had a 125% increased risk of END (OR 2.25; 95% CI 1.71–4.86,P=0.005). After adjustment for fibrinogen and high-sensitivity C-reactive protein, MetS remained significantly correlated to END (OR 2.20; 95% CI 1.10–4.04,P=0.026) with a 77% elevated risk per additional MetS trait (OR 1.77; 95% CI 1.23–2.58,P=0.002).Conclusions. This study demonstrated that MetS may be a potential predictor for END after ischemic stroke, which was independent of raised inflammatory mediators.

Background: Non-occlusive thrombus in an intracranial artery in acute ischemic stroke is an uncommon occurrence. We compared the clinical course and outcome of intracranial subocclusive to occlusive thrombi. Methods: We conducted a review of patients who presented with acute ischemic stroke and received CT angiogram at a single comprehensive stroke center from January 2018 to December 2019. Patients with intracranial subocclusive thrombus were compared to a control group with complete occlusion matched for occlusion location. Subocclusive thrombus was reviewed by two raters on CT angiography, disagreement resolved by consensus. Patient and stroke characteristics and the clinical course were analyzed. Neurological deterioration was defined as an increase in NIH Stroke Scale (NIHSS) score > 4 compared from baseline to 48 hours. Good outcome at discharge was defined as modified Rankin Score of ≤2. Results: Among 1151 acute ischemic strokes, there were 896 patients with CT angiograms. Sixteen out of 896 (1.8%) patients had intracranial subocclusive thrombus. Thirty-two with comparable intracranial occlusions were identified. In the subocclusive group, 3 of 16 (19%) of received acute endovascular intervention, compared to 13 of 32 (41%) in the occluded group. Sex, median age or time from last known well to hospital arrival did not differ between the two groups. The subocclusive thrombus group had less severe strokes, with median NIHSS score at arrival 3 compared to 8.5 in the occlusion group (p<0.01) and median NIHSS at discharge 1 compared to 5.5 in the occlusive group (p<0.01). Frequency of neurological deterioration in hospital did not differ between the subocclusive and occluded groups at 48 hours (15% vs 15% p=1.00). The subocclusive group was associated with a good outcome at discharge, OR 0.5.71, 95% confidence interval 1.41-23.1. Conclusion: Intracranial subocclusive thrombus in acute ischemic stroke has a more mild presentation compared to complete intracranial occlusion without a high rate of neurological deterioration.

Objective:To explore the association between blood pressure (BP) levels after endovascular thrombectomy (EVT) and the clinical outcomes of acute ischemic stroke (AIS) patients with large vessel occlusion (LVO).Methods:A study was eligible if it enrolled AIS patients older than 18 years, with an LVO treated with either successful or unsuccessful EVT, and provided either individual or mean 24-hour systolic BP values after the end of the EVT procedure. Individual patient data from all studies were analyzed using a generalized linear mixed-effects model.Results:A total of 5874 patients (mean age: 69±14 years, 50% women, median NIHSS on admission: 16) from 7 published studies were included. Increasing mean systolic BP levels per 10 mm Hg during the first 24 hours after the end of the EVT were associated with a lower odds of functional improvement (unadjusted common OR=0.82, 95%CI:0.80-0.85; adjusted common OR=0.88, 95%CI:0.84-0.93) and modified Ranking Scale score≤2 (unadjusted OR=0.82, 95%CI:0.79-0.85; adjusted OR=0.87, 95%CI:0.82-0.93), and a higher odds of all-cause mortality (unadjusted OR=1.18, 95%CI:1.13-1.24; adjusted OR=1.15, 95%CI:1.06-1.23) at 3 months. Higher 24-hour mean systolic BP levels were also associated with an increased likelihood of early neurological deterioration (unadjusted OR=1.14, 95%CI:1.07-1.21; adjusted OR=1.14, 95%CI:1.03-1.24) and a higher odds of symptomatic intracranial hemorrhage (unadjusted OR=1.20, 95%CI:1.09-1.29; adjusted OR=1.20, 95%CI:1.03-1.38) after EVT.Conclusion:Increased mean systolic BP levels in the first 24 hours after EVT are independently associated with a higher odds of symptomatic intracranial hemorrhage, early neurological deterioration, three-month mortality, and worse three-month functional outcomes.

Introduction: Hemorrhagic transformation (HT) after acute ischemic stroke (AIS) may contribute to neurologic deterioration. The current radiologic classification of HT is qualitative and distinguishes petechial hemorrhagic infarction from parenchymal hematoma (PH-1 and PH-2). However, this grading scheme is subjective and may not accurately reflect the impact of HT on neurological status and outcome. We sought to evaluate whether the volume of hemorrhage was a better marker of deterioration. Methods: We evaluated AIS patients with follow-up CT imaging from a prospective stroke genetics study. HT seen within 36 hours of AI was classified using ECASS criteria. In addition, we outlined all confluent areas of hemorrhage to derive hemorrhage volume (HV). We calculated ΔNIHSS as the difference between baseline and 24-hour NIHSS. Early neurological deterioration (END) was defined as ΔNIHSS of -4 points or more. Association of radiologic HT grade and HV with ΔNIHSS and END were analyzed using linear regression and receiver-operating-curve testing. Results: We analyzed 948 stroke patients with median NIHSS 7 (IQR 4-14), 64% receiving tPA and ΔNIHSS +2 (IQR 0-5). 294 (31%) had HT (146 HI1, 63 HI2, 42 PH1 and 43 PH2). HT was associated with higher baseline NIHSS but not with tPA treatment or ΔNIHSS. END occurred in 113 (12%) including 46 with HT (16%) vs. 67 (10%) without HT (p=0.02). Amongst those with HT, the radiologic grade was not associated with ΔNIHSS or END (20% of PH2, 20% of PH1 vs. 15% of HI1/HI2, p=0.40). However, greater HV was associated with ΔNIHSS (adjusting for baseline NIHSS and tPA, estimate -1.5 point per 10-ml, p=0.0001) and with END (those with END had median HV 7 vs. 3-ml, p=0.001). A cut-off of 12-ml had 45% sensitivity and 90% specificity for END (AUC of 0.72). Conclusion: We demonstrated that while HT was associated with a higher risk of END, the ECASS classification alone did not distinguish those who worsened. It appears that hemorrhage volume may better predict worsening NIHSS and END with moderate sensitivity.

Early Neurological Deterioration

Background Early neurological deterioration occurs in approximately 10% acute ischemic stroke patients after thrombolysis. Over half of the early neurological deterioration occurred without known causes and is called unexplained early neurological deterioration. Aims We aimed to explore the development of early neurological deterioration at 24 h after thrombolysis, and whether it could be predicted by the presence of baseline hypoperfusion in lenticulostriate arteries territory in acute ischemic stroke patients. Methods We retrospectively reviewed our prospectively collected database of acute ischemic stroke patients in the unilateral middle cerebral artery territory who had baseline perfusion image and received thrombolysis. Unexplained early neurological deterioration was defined as ≥ 2 points increase of National Institutes of Health Stroke Scale (NIHSS) from baseline to 24 h, without known causes. Hypoperfusion lesions in different territories were identified on perfusion maps. Results A total of 306 patients were included in analysis. Patients with pure lenticulostriate arteries hypoperfusion (defined as the presence of hypoperfusion in lenticulostriate artery territory, but not in middle cerebral artery terminal branch territory) were more likely to have unexplained early neurological deterioration than others (27.6% vs. 6.1%; OR, 5.974; p = 0.001), after adjusting for age, baseline NIHSS and onset to treatment time. Conclusions Patients presenting hypoperfusion in pure lenticulostriate arteries territory were easier to experience unexplained early neurological deterioration.

Background and Purpose— In Japan, nearly half of ischemic stroke patients receive edaravone for acute treatment. The purpose of this study was to assess the effect of edaravone on neurological symptoms in patients with ischemic stroke stratified by stroke subtype. Methods— Study subjects were 61 048 patients aged 18 years or older who were hospitalized ≤14 days after onset of an acute ischemic stroke and were registered in the Japan Stroke Data Bank, a hospital-based multicenter stroke registration database, between June 2001 and July 2013. Patients were stratified according to ischemic stroke subtype (large-artery atherosclerosis, cardioembolism, small-vessel occlusion, and cryptogenic/undetermined) and then divided into 2 groups (edaravone-treated and no edaravone). Neurological symptoms were evaluated using the National Institutes of Health Stroke Scale (NIHSS). The primary outcome was changed in neurological symptoms during the hospital stay (ΔNIHSS=NIHSS score at discharge−NIHSS score at admission). Data were analyzed using multivariate linear regression with inverse probability of treatment weighting after adjusting for the following confounding factors: age, gender, and systolic and diastolic blood pressure at the start of treatment, NIHSS score at admission, time from stroke onset to hospital admission, infarct size, comorbidities, concomitant medication, clinical department, history of smoking, alcohol consumption, and history of stroke. Results— After adjusting for potential confounders, the improvement in NIHSS score from admission to discharge was greater in the edaravone-treated group than in the no edaravone group for all ischemic stroke subtypes (mean [95% CI] difference in ΔNIHSS: −0.46 [−0.75 to −0.16] for large-artery atherosclerosis, −0.64 [−1.09 to −0.2] for cardioembolism, and −0.25 [−0.4 to −0.09] for small-vessel occlusion). Conclusions— For any ischemic stroke subtype, edaravone use (compared with no use) was associated with a greater improvement in neurological symptoms, although the difference was small (<1 point NIHSS) and of limited clinical significance.
