Background and Purpose: As endovascular therapy (EVT) occupies a growing role in the management of acute ischemic stroke (AIS), contrast-induced nephropathy (CIN) associated with consecutive contrast media administration for vascular imaging and distal subtraction angiography is an emerging concern. We investigated the incidence, risk factors and clinical outcome of CIN in AIS patients who underwent EVT. Methods: Multicenter data from the ASIAN KR registry collected between January 2011 and Mar 2016, on consecutive patients who received EVT for AIS, were analyzed. Diagnostic criteria for CIN were: an absolute increase in serum creatinine (SCr) by ≥0.3 mg/dL from baseline within 48 hours after EVT; or a relative increase in SCr levels by ≥50% from baseline. Results: Of 721 patients, 616 patients (85%) were eligible for this study. CIN was diagnosed in 47 (7.6%), and was more associated with history of hypertension (p=0.011), history of diabetes mellitus (DM) (p=0.002), and higher initial NIHSS score (16.6 vs. 18.7 p=0.006). In multivariable analysis, independent risk factors of CIN were hypertension history (OR 2.465, 95% CI 1.027-5.919, p=0.043), DM history (1.978, 1.023-3.822, p=0.042), initial NIHSS score (1.071, 1.014-1.132, p=0.014), initial SCr level (1.603, 1.159-2.217, p=0.004) and duration from puncture to final angiography (1.006 per minute, 1.000-1.012, p=0.045). In multiple logistic regression, CIN was an independent risk factor of poor clinical outcome (modified Rankin Scale at 3 months 4-6; 3.782, 1.770-8.083, p=0.001) after adjusting age, sex, initial NIHSS, hypertension history, DM history, onset to puncture time and successful reperfusion. Conclusions: CIN is not uncommon and associated with poor clinical outcome after EVT in AIS. Clinicians should be aware that key factors associated with an increased likelihood of CIN are hypertension history, DM history, abnormal SCr level, higher NIHSS score and longer procedure duration.

Background and Purpose: There is limited information on symptomatic intracranial hemorrhage (sICH) in stroke patients without thrombolysis. This study aimed to evaluate the risk factors of sICH and the association between sICH and the prognosis at 3 and 12 months in acute ischemic stroke patients without thrombolysis.Methods: Data originated from the Chinese Acute Ischemic Stroke Treatment Outcome Registry. Univariate analysis and multivariate logistic regression were used to screen the risk factors of sICH. Multivariable logistic regression models were used to assess the association of sICH with poor outcome and all-cause mortality.Results: Totally, 9,484 patients were included, of which 69 (0.73%) had sICH. Atrial fibrillation (odds ratio [OR], 3.682; 95% confidence interval [CI], 1.945–6.971; p < 0.001), history of tumors (OR, 2.956; 95% CI, 1.115–7.593; p = 0.024), and the National Institutes of Health Stroke Scale (NIHSS) score on admission ([6–15: OR, 2.344; 95% CI, 1.365–4.024; p = 0.002] [>15: OR, 4.731; 95% CI, 1.648–13.583; p = 0.004]) were independently associated with sICH. After adjustment of the confounders, patients with sICH had a higher risk of poor outcome (OR, 1.983; 95% CI, 1.117–3.521; p = 0.018) at 3 months and that of all-cause mortality at 3 (OR, 6.135; 95% CI, 2.328–16.169; p < 0.001) and 12 months (OR, 3.720; 95% CI, 1.513–9.148; p = 0.004).Conclusion: sICH occurred in 0.73% of acute ischemic stroke patients without thrombolysis and was associated with a worse prognosis at 3 and 12 months. Atrial fibrillation, history of tumors, and NIHSS score at admission were independent risk factors of sICH.

Introduction: Ischemic stroke is the cause for major morbidity and mortality in reversible cerebral vasoconstriction syndrome (RCVS). While there is evidence to suggest that ischemic stroke in RCVS is associated with proximal vasoconstriction, it is still unclear why some patients develop ischemic lesions. The aim of this study was to evaluate the risk factors and outcomes of ischemic stroke in RCVS. Methods: We utilized the Nationwide Readmissions Database 2016-2017 to identify all hospitalizations with the discharge diagnosis of RCVS. Occurrence of acute ischemic stroke was identified. Hospitalizations with the diagnosis of hemorrhagic stroke were excluded. Survey design methods were used to generate national estimates. Independent predictors of ischemic stroke were analyzed using multivariable logistic regression analysis with results expressed as odds ratio (OR) and 95% confidence intervals (CI). Results: Among the total 1,065 hospitalizations for RCVS during the study period (mean±SD age: 49.0±16.7 years, female 69.7%), 267 (25.1%) had occurrence of acute ischemic stroke. Patients with ischemic stroke were more likely to have history of hypertension (OR 2.33, 95% CI 1.51-3.60), diabetes (OR 1.81, 95% CI 1.11-2.98), and tobacco use (OR 1.64, 95% CI 1.16-2.33) and less likely to have a history of migraine (OR 0.56, 95% CI 0.35-0.90). Patients with stroke were more likely to develop cerebral edema. They also had longer hospital stay, higher hospital charges, and lower likelihood of being discharged to home or inpatient rehabilitation facility. They had higher in-hospital mortality rate, the difference was however not statistically significant. Conclusion: In conclusion, ischemic stroke affects nearly 25% of patients with RCVS and is associated with an increased rate of other neurologic complications and worse functional outcomes. Patients with traditional cerebrovascular risk factors might have a higher predisposition for developing the ischemic lesions.

OBJECTIVE Tandem occlusions continue to represent a major challenge in patients with acute ischemic stroke (AIS). The anterograde approach with proximal to distal revascularization as well as the retrograde approach with distal to proximal revascularization have been reported without clear consensus or standard guidelines. METHODS The authors performed a comprehensive search of the PubMed database for studies including patients with carotid occlusions and tandem distal occlusions treated with endovascular therapy. They reviewed the type of approach employed for endovascular intervention and clinical outcomes reported with emphasis on the revascularization technique. They also present an illustrative case of AIS and concurrent proximal cervical carotid occlusion and distal middle cerebral artery occlusion from their own experience in order to outline the management dilemma for similar cases. RESULTS A total of 22 studies were identified, with a total of 790 patients with tandem occlusions in AIS. Eleven studies used the anterograde approach, 3 studies used the retrograde approach, 4 studies used both, and in 4 studies the approach was not specified. In the studies that reported Thrombolysis in Cerebral Infarction (TICI) grades, an average of 79% of patients with tandem occlusions were reported to have an outcome of TICI 2b or better. One study found good clinical outcome in 52.5% of the thrombectomy-first group versus 33.3% in the stent-first group, as measured by the modified Rankin Scale (mRS). No study evaluated the difference in time to reperfusion for the anterograde and retrograde approach and its association with clinical outcome. The patient in the illustrative case had AIS and tandem occlusion of the internal carotid and middle cerebral arteries and underwent distal revascularization using a Solitaire stent retrieval device followed by angioplasty and stent treatment of the proximal cervical carotid occlusion. The revascularization was graded as TICI 2b; the postintervention National Institutes of Health Stroke Scale (NIHSS) score was 17, and the discharge NIHSS score was 7. The admitting, postoperative, and 30-day mRS scores were 5, 1, and 1, respectively. CONCLUSIONS In stroke patients with tandem occlusions, distal to proximal revascularization represents a reasonable treatment approach and may offer the advantage of decreased time to reperfusion, which is associated with better functional outcome. Further studies are warranted to determine the best techniques in endovascular therapy to use in this subset of patients in order to improve clinical outcome.

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.

Background and purposeTo determine the initial factors, including patient characteristics, stroke etiology and severity, time factors, and imaging findings, that could affect the clinical outcome of patients with acute ischemic stroke (AIS) caused by basilar artery occlusion (BAO) where successful recanalization was achieved via mechanical thrombectomy.MethodsBetween March 2011 and December 2014, 35 patients with AIS caused by BAO received MRI/MR angiography-based mechanical thrombectomies, and recanalization was achieved with a Thrombolysis In Cerebral Infarction score of >2b. The patients were divided into a good outcome group (n=19), defined as those with a modified Rankin Scale (mRS) score of 0–2 at 3 months after stroke onset, and a poor outcome group (n=16), defined as a mRS score of 3–6. The differences between the groups were analyzed.ResultsInitial National Institutes of Health Stroke Scale (NIHSS) score (good vs poor: 17.9±8.9 vs 27.6±8.5, p=0.003), posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) based on initial diffusion-weighted images (DWI) (good vs poor: 7.8±1.6 vs 5.4±1.8, p=0.001), pc-ASPECTS based on contrast staining on the post-thrombectomy control CT (good vs poor: 9.2±1.5 vs 6.3±2.2, p<0.001), and presence of contrast staining in the brainstem on that CT (good vs poor: 15.8% vs 81.6%, p<0.001) were significantly different between the groups.ConclusionsPatients with AIS caused by BAO with a lower initial NIHSS score, fewer lesions on initial DWI, and less contrast staining on the post-thrombectomy control CT have higher probabilities of a good clinical outcome after successful recanalization via a mechanical thrombectomy.

Background: CT angiography (CTA) and CT perfusion (CTP) are important diagnostic tools in acute ischemic stroke. We investigated the prognostic value of CTA and CTP for clinical outcome and determined whether they have additional prognostic value over patient characteristics and non-contrast CT (NCCT). Methods: We included 1,374 patients with suspected acute ischemic stroke in the prospective multicenter Dutch acute stroke study. Sixty percent of the cohort was used for deriving the predictors and the remaining 40% for validating them. We calculated the predictive values of CTA and CTP predictors for poor clinical outcome (modified Rankin Scale score 3-6). Associations between CTA and CTP predictors and poor clinical outcome were assessed with odds ratios (OR). Multivariable logistic regression models were developed based on patient characteristics and NCCT predictors, and subsequently CTA and CTP predictors were added. The increase in area under the curve (AUC) value was determined to assess the additional prognostic value of CTA and CTP. Model validation was performed by assessing discrimination and calibration. Results: Poor outcome occurred in 501 patients (36.5%). Each of the evaluated CTA measures strongly predicted outcome in univariable analyses: the positive predictive value (PPV) was 59% for Alberta Stroke Program Early CT Score (ASPECTS) ≤7 on CTA source images (OR 3.3; 95% CI 2.3-4.8), 63% for presence of a proximal intracranial occlusion (OR 5.1; 95% CI 3.7-7.1), 66% for poor leptomeningeal collaterals (OR 4.3; 95% CI 2.8-6.6), and 58% for a >70% carotid or vertebrobasilar stenosis/occlusion (OR 3.2; 95% CI 2.2-4.6). The same applied to the CTP measures, as the PPVs were 65% for ASPECTS ≤7 on cerebral blood volume maps (OR 5.1; 95% CI 3.7-7.2) and 53% for ASPECTS ≤7 on mean transit time maps (OR 3.9; 95% CI 2.9-5.3). The prognostic model based on patient characteristics and NCCT measures was highly predictive for poor clinical outcome (AUC 0.84; 95% CI 0.81-0.86). Adding CTA and CTP predictors to this model did not improve the predictive value (AUC 0.85; 95% CI 0.83-0.88). In the validation cohort, the AUC values were 0.78 (95% CI 0.73-0.82) and 0.79 (95% CI 0.75-0.83), respectively. Calibration of the models was satisfactory. Conclusions: In patients with suspected acute ischemic stroke, admission CTA and CTP parameters are strong predictors of poor outcome and can be used to predict long-term clinical outcome. In multivariable prediction models, however, their additional prognostic value over patient characteristics and NCCT is limited in an unselected stroke population.

Background The long‐term incidence of acute myocardial infarction (AMI) in patients with acute ischemic stroke (AIS) has not been well defined in large cohort studies of various race‐ethnic groups. Methods and Results A prospective cohort of patients with AIS who were registered in a multicenter nationwide stroke registry (CRCS‐K [Clinical Research Collaboration for Stroke in Korea] registry) was followed up for the occurrence of AMI through a linkage with the National Health Insurance Service claims database. The 5‐year cumulative incidence and annual risk were estimated according to predefined demographic subgroups, stroke subtypes, a history of coronary heart disease (CHD), and known risk factors of CHD. A total of 11 720 patients with AIS were studied. The 5‐year cumulative incidence of AMI was 2.0%. The annual risk was highest in the first year after the index event (1.1%), followed by a much lower annual risk in the second to fifth years (between 0.16% and 0.27%). Among subgroups, annual risk in the first year was highest in those with a history of CHD (4.1%) compared with those without a history of CHD (0.8%). The small‐vessel occlusion subtype had a much lower incidence (0.8%) compared with large‐vessel occlusion (2.2%) or cardioembolism (2.4%) subtypes. In the multivariable analysis, history of CHD (hazard ratio, 2.84; 95% CI, 2.01–3.93) was the strongest independent predictor of AMI after AIS. Conclusions The incidence of AMI after AIS in South Korea was relatively low and unexpectedly highest during the first year after stroke. CHD was the most substantial risk factor for AMI after stroke and conferred an approximate 5‐fold greater risk.

Abstract Background Atherosclerosis is a chronic inflammatory process that occurs in the arterial wall. This immuno-inflammatory process plays a role throughout all stages of stroke. Neutrophils, lymphocytes, and platelets are crucial blood cells for innate and adaptive immunity. This study investigated the associations of four types of immuno-inflammatory markers, namely the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and neutrophil count (NC), with clinical outcomes in patients with acute ischemic stroke. Methods In this retrospective study, we enrolled 2903 inpatients with acute ischemic stroke from May 2010 to May 2019. Data included risk factors, laboratory parameters, and clinical features during hospitalization. The National Institutes of Health Stroke Scale (NIHSS), and modified Rankin Scale (mRS) were used to assess stroke severity and outcomes. Results All four immuno-inflammatory markers exhibited positive linear correlations with age, glucose, creatinine, length of hospital stay, NIHSS score on admission, and mRS score at discharge. The levels of the four immuno-inflammatory markers were significantly higher in patients with large-artery atherosclerosis and cardioembolism and were highest in patients with other determined etiology. Patients with levels of immuno-inflammatory markers higher than their cutoff values for unfavorable outcomes also exhibited higher rates of cancer history (except for SII and NC), uremia (except for NC), elevated troponin I, and in-hospital complications. Multivariate analysis including SII revealed that admission NIHSS score ≥ 5, age > 75 years, SII > 724, diabetes mellitus, female sex, elevated troponin I, heart disease, and prior stroke were significant predictors for unfavorable outcomes. These significant predictors were retained after replacing SII > 724 with NLR > 143, PLR > 3.5, or NC > 6 × 10 3 /mL, except for prior stroke. For a basic model comprising seven significant predictors of unfavorable outcomes, the C-statistic was 0.860. The addition of SII, NLR, and PLR to the basic model resulted in a significant improvement in the prediction performance to 0.864, 0.863, and 0.863, respectively. Conclusions Immuno-inflammatory markers provide more useful information than conventional risk factors and other laboratory parameters for the prediction of stroke outcomes. SII > 724 is the most appropriate marker when combined with other predictors.

The Relationship

This study aimed to investigate the relationship between the bispectral index and the National Institutes of Health Stroke Scale (NIHSS) score in patients admitted to the emergency department with a first-time acute ischemic stroke. Methods: This prospective, observational study was conducted with patients admitted to our clinic with acute ischemic stroke symptoms. Patients with known cranial pathologies, such as space- occupying lesions, those with a history of clinically significant cerebrovascular events or sedative drug administration, and those with altered consciousness due to metabolic causes were excluded from the study. The National Institutes Health Stroke Scale scores were recorded by the clinician. Cerebral arterial territories were assessed on DWI and CT. The relationship between the NIHSS score and bispectral index was evaluated. Results: Forty-three patients were included in the study. The mean bispectral index of the cases was 84.23 ± 9.50. There was no significant correlation between the bispectral index values and the NIHSS score (p<0.05). Conclusion: In our study, the bispectral index values were decreased due to ischemic stroke. The results should be reevaluated studies conducted with larger series to reveal the relationship between infarcted territories, NIHSS score, bispectral index, and the GCS score.
