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: 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 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.

Abstract Studies on the association of C-reactive protein (CRP) with all-cause mortality in acute ischemic stroke patients have yielded conflicting results. The objective of this meta-analysis was to evaluate the prognostic value of CRP elevation in predicting all-cause mortality amongst patients with acute ischemic stroke. We searched the original observational studies that evaluated the association of CRP elevation with all-cause mortality in patients with acute ischemic stroke using PubMed and Embase databases until 20 January 2018. Pooled multivariate-adjusted hazard ratio (HR) with 95% confidence intervals (CI) of all-cause mortality was obtained for the highest compared with the lowest CRP level or per unit increment CRP level. A total of 3604 patients with acute ischemic stroke from eight studies were identified. Acute ischemic stroke patients with the highest CRP level were independently associated with an increased risk of all-cause mortality (HR: 2.07; 95% CI: 1.60–2.68) compared with the lowest CRP category. The pooled HR of all-cause mortality was 2.40 (95% CI: 1.10–5.21) for per unit increase in log-transformed CRP. Elevated circulating CRP level is associated with the increased risk of all-cause mortality in acute ischemic stroke patients. This meta-analysis supports the routine use of CRP for the death risk stratification in such patients.

Background: Inflammation plays a role in the pathophysiology of cerebral ischemic and also an initial response to brain injury. Inflammation involving Blood and Brain Barrier disturbance, leukocyte infiltration, endothelial cells activation, oxidant and inflammatory mediator buildups which can develop rapidly within hours and can cause secondary injury to brain tissues Objectives: To determine the correlation between Neutrophil-to-Lymphocyte Ratio (NLR) and High Sensitivity C Reactive Protein (hsCRP) with severity and outcome in acute ischemic stroke patients Methods: This study used a cross-sectional design approach. Sampling was done at H. Adam Malik General Hospital Medan and taken as many as 38 subjects. NLR and hsCRP were examined on the first day of admission. Severity was assessed by using the National Institutes of Health Stroke Scale and the outcome was assessed by using the Modified Ranking Scale on the first and fourteenth day of admission. The data analysis used the contingency coefficient correlation test and gamma test. Results: Demographic characteristics of the subjects are; the average age is 62 years old, the highest educational level is high school graduate, and the most occupation is unemployed. There is a positive, moderate, and significant correlation between NLR and severity of acute ischemic stroke (r=0.511; p=0.001). There is a positive, moderate, and significant correlation between NLR and the outcome of acute ischemic stroke (r=0.463; p=0.001). There is a positive, very strong, and significant correlation between hsCRP and severity of acute ischemic stroke (r=0.896; p=0.001). There is a positive, strong, and significant correlation between hsCRP and outcome of acute ischemic stroke (r=0.624; p=0.001) Conclusions: There is a positive and significant correlation between NLR and hsCRP with severity and outcome in acute ischemic stroke patients.

Background and Purpose: Early neurological deterioration (END) occurs in 10-40% of acute ischemic stroke (AIS) patients and has been associated with worse outcome. Recent improvements in treatment may have reduced the prevalence of END. A single early control or repeated observations have been applied to detect END close to occurrence, in order to improve the poor outcome associated with END, as clinical interventions may still be effective. Deterioration detected through repeated observations may be transitory or lead to END. Our aim was to study outcome after END and transitory deterioration (TD). Methods: In acute ischemic stroke patients, key Scandinavian Stroke Scale (SSS) items were scored 12 times from admission to 72 h. END was defined as ≥2 point decrease in any key SSS item from admission to 72 h. Early deterioration episode was defined as similar worsening between two consecutive assessments within 72 h, and TD as early deterioration episode in patients without END. Main outcome measures were odds ratios (OR) for worse functional outcome (including death) measured by modified Rankin scale at 90 days for END and TD compared with stable patients. Results: 368 patients were included. 13.9% had END and 28.3% had TD. Both deterioration groups were associated with worse outcome at 12 weeks compared with stable patients, with ORs of 35.1 (95% CI 8.8-140) for death/dependency and 5.8 (95% CI 1.8-19.4) for death in END patients and ORs of 2.3 (95% CI 1.1-4.8) for death/dependency and 1.9 (95% CI 0.5-6.3) for death in patients with TD. LOS increased by 6.4 days for END (p < 0.001) and 1.1 days for TD (p = 0.014) compared with stable patients. Conclusion: We found a strong association between END and worse outcome, and even TD doubled the OR for death/dependency compared to stable patients. Early deterioration episodes identified through frequent observations are therefore clinically significant and such frequent observations may detect worsening sufficiently close to occurrence for potentially effective treatment to be applied.

Abstract Background Susceptibility weighted imaging (SWI) provides an approximate assessment of tissue perfusion and shows prominent hypointense cortical veins in the ischemic territory because of the increased concentration of deoxyhemoglobin. We aimed to evaluate whether asymmetrical prominent cortical vein sign (APCVS) on SWI can predict early neurological deterioration (END) in acute ischemic stroke patients with severe intracranial arterial stenosis or occlusion (SIASO). Methods One hundred and nine acute ischemic stroke patients with SIASO who underwent SWI were retrospectively recruited. END was defined as an increase in the National Institutes of Health Stroke Scale score ≧2 points despite standard treatment in the first 72 h after admission. The APCVS was defined as more and/or large vessels with greater signal loss than those in the opposite hemisphere on SWI. Results Thirty out of the 109 (27.5%) patients developed END. Sixty (55.0%) patients presented with APCVS on SWI. APCVS occurred in 24 (80%) patients with END, whereas it only occurred in 36 (45.6%) patients without END (P = 0.001). Patients with APCVS were more likely to have END (40.0%, vs. 12.2%, P = 0.001) than those without END. Multivariate logistic regression indicated that APCVS (OR = 4.349, 95% C.I. = 1.580–11.970, P = 0.004) was a significant predictor of END in acute ischemic stroke patients with SIASO, adjusted for previous stroke history and acute infarct volume. Conclusions In acute ischemic stroke patients with SIASO, the APCVS might be a useful neuroimaging marker for predicting END, which suggests the importance of evaluation of perfusion status.
