Aim. To study the prevalence of cognitive and emotional impairment following a minor ischemic stroke compared to an age-matched group with non-ST-elevation myocardial infarction (NSTEMI). Methods. We included patients aged 18-70 years with a minor ischemic stroke defined as modified Rankin Scale (mRS) 0-2 at day 7 or at discharge if before and age-matched NSTEMI patients with the same functional mRS. We applied a selection of cognitive tests and the patients completed a questionnaire comprising of Hospital Anxiety and Depression scale (HADS) and Fatigue Severity Scale (FSS) at follow-up 12 months after the vascular event. Results of cognitive tests were also compared to normative data. Results. 325 ischemic stroke and 144 NSTEMI patients were included. There was no significant difference in cognitive functioning between ischemic stroke and NSTEMI patients. Minor stroke patients and to a lesser extent NSTEMI patients scored worse on more complex cognitive functions including planning and implementation of activities compared to validated normative data. For the minor stroke patients the location of the ischemic lesion had no influence on the result. The prevalence of anxiety, depression, and fatigue was significantly higher in the stroke group compared to the NSTEMI group. Depression was independently associated with reduced cognitive function. Discussion and Conclusion. Minor ischemic stroke patients, and to lesser degree NSTEMI patients, had reduced cognitive function compared to normative data, especially executive functioning, on 12-month follow-up. The difference in cognitive function between stroke and NSTEMI patients was not significant. Depression was associated with low scores on cognitive tests highlighting the need to adequately address emotional sequelae when considering treatment options for cognitive disabilities.

ObjectiveEvidence about whether neutrophil counts or neutrophil ratio is associated with new stroke is scant. The aim of this study is to assess the association of neutrophil counts or neutrophil ratio with a new stroke in patients with minor stroke or TIA.MethodsWe derived data from the Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events trial. Patients with a minor stroke or TIA were categorized into 4 groups according to the quartile of neutrophil counts or neutrophil ratio. The primary outcome was a new stroke (ischemic or hemorrhagic), and secondary outcomes included a new composite vascular event (stroke, myocardial infarction, or death resulting from cardiovascular causes) and ischemic stroke during the 90-day follow-up. We assessed the association between neutrophil counts, neutrophil ratio, and risk of new stroke.ResultsA total of 4,854 participants were enrolled, among whom 495 had new strokes at 90 days. Compared with the first quartile, the second, third, and fourth quartiles of neutrophil counts were associated with increased risk of new stroke (adjusted hazard ratio 1.40 [95% confidence interval (CI) 1.05–1.87], 1.55 [95% CI 1.17–2.05], and 1.69 [95% CI 1.28–2.23], respectively, p for trend <0.001). Similar results were observed for the endpoint of composite events and ischemic stroke. Parallel results were found for neutrophil ratio.ConclusionHigh levels of both neutrophil counts and neutrophil ratio were associated with an increased risk of new stroke, composite events, and ischemic stroke in patients with a minor ischemic stroke or TIA.

Purpose and Objective: There have been limited reports that focused on cognitive impairment in acute ischemic stroke after endovascular treatment. The aim of this study, therefore, was to investigate cognitive function in patient after endovascular treatment in acute phase and at 6 months follow-up. Method: In this prospective study, from December 2016 to November 2018, the patients who were diagnosed as ischemic stroke with occlusion of the internal carotid artery and of the middle cerebral artery and treated with endovascular treatment were enrolled. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA-J) test within 5 days of onset and at 6 months follow-up. We defined cognitive impairment as a score of <24 in MoCA-J. Results: 150 patients were enrolled. MoCA-J was feasible in 69 patients (median 76 years; 49 female) (46%), in acute phase (Figure A). 63 patients (91%) had cognitive impairment and no significant differences were found in the naming and the abstraction domains between MoCA-J <24 group and ≧24 group. At 6 months follow-up, 48 patients (median 72 years; 12 female) were assessed with MoCA-J and 35 patients (73%) had cognitive impairment. However, only one patient scored less at 6 months follow-up than in acute phase (Figure B), which resulted in the significant increase in the median MoCA-J score (7 vs. 21, P<0.05) (Figure C) and in all the domains except for the language (P=0.078) (Figure D). Conclusion: In acute phase of ischemic stroke after endovascular treatment, MoCA-J was feasible in about 45%, in which 91% had cognitive impairment. However, at 6 months follow-up, the median MoCA-J score was significantly higher and less number of patients had cognitive impairment. The present results suggest that cognition recovers with time after endovascular treatment in ischemic stroke.

Introduction and Purpose: Our aim was to review the characteristics of transient ischemic attack (TIA) and minor ischemic stroke patients monitored for atrial fibrillation (AF) epidoses detection within the first 4weeks after stroke to assess AF predictors. Materials and Methods: TIA and minor ischemic stroke patients (nihss≤ 5) were selected from CRYPTO-AF database. CRYPTO-AF is a prospective multicentre registry of patients with cryptogenic stroke older of 55 year-old. Monitoring started within the first 72 hours from stroke symptoms onset and was prolonged for 4 weeks. Clinical, cardiographic and blood test parameters of patients included were reviewed. Fisher exact and Mann Whitney tests were used to analyze categorical and continuous data. Results: In our cohort of 152 transient and minor ischemic stroke patients, 55.9% were men, mean age 73.18±10.24 and median NIHSS score was 2.31(0-5). A total of 30 patients (20.3%) were diagnosed with AF in the first month of monitoring, 6 patients (5.7%) within the first 3 days, 14 patients (13.3%) between 3 days and to 2 weeks of monitoring, and 14 partientes (12.4%) between the second and the fourth week. In these transient and minor ischemic stroke patients, age (p< 0.031), left atrial volume index (p< 0.023), the appearance of isolated extrasystoles during monitoring (p< 0.021), Type B natriuretic peptide (p< 0.011) and the longitudinal strain (p< 0.019) appeared as independet precitors of AF. However in the multivariate analysis adjusted for the above variables, only left atrial strain (OR 0.89, 95% CI: 0.797-0.991, p< 0.034) independently predicts AF detection. Conclusions: In our serie, only the left atrial strain appeared as a indepent predictor of AF. Given the known pathophysiology of TIA and minor ischemic stroke, the description of AF predictors would help to identify those patients who would benefit from completing a longer monitoring. More studies are needed to identify these predictors.

An easily scoring system to predict the risk of cognitive impairment after minor ischemic stroke has not been available. We aimed to develop and externally validate a nomogram for predicting the probability of post-stroke cognitive impairment (PSCI) among hospitalized population with minor stroke. Moreover, the association of Trimethylamine N-oxide (TMAO) with PSCI is also investigated. We prospectively conducted a developed cohort on collected data in stroke center from June 2017 to February 2018, as well as an external validation cohort between June 2018 and February 2019. The main outcome is cognitive impairment defined as &lt;22 Montreal Cognition Assessment (MoCA) score points 6 – 12 months following a minor stroke onset. Based on multivariate logistic models, the nomogram model was generated. Plasma TMAO levels were assessed at admission using liquid chromatography tandem mass spectrometry. A total of 228 participants completed the follow-up data for generating the nomogram. After multivariate logistic regression, seven variables remained independent predictors of PSCI to compose the nomogram included age, female, Fazekas score, educational level, number of intracranial atherosclerotic stenosis (ICAS), HbA1c, and cortical infarction. The area under the receiver-operating characteristic (AUC-ROC) curve of model was 0.829, C index was good (0.810), and the AUC-ROC of the model applied in validation cohort was 0.812. Plasma TMAO levels were higher in patients with cognitive impairment than in them without cognitive dysfunction (median 4.56 vs. 3.22 μmol/L; p ≤ 0.001). In conclusion, this scoring system is the first nomogram developed and validated in a stroke center cohort for individualized prediction of cognitive impairment after minor stroke. Higher plasma TMAO level at admission suggests a potential marker of PSCI.

Introduction: Revascularization is a robust therapy for acute ischemic stroke, but animal studies suggest that reperfusion edema may attenuate its beneficial effects. In stroke patients, early reperfusion consistently reduces infarct volume and improves long-term functional outcome, but there is little clinical data available regarding reperfusion edema. We sought to elucidate the relationship between reperfusion and brain edema in a patient cohort of moderate to severe stroke. Methods: Seventy-one patients enrolled in the Echoplanar Imaging Thrombolysis Evaluation Trial (EPITHET) with serial brain magnetic resonance imaging and perfusion-weighted imaging (PWI) were analyzed. Reperfusion percentage was calculated based on the difference in PWI lesion volume at baseline and follow-up (day 3-5). Midline shift (MLS) was measured on the day 3-5 fluid attenuated inversion recovery (FLAIR) sequence. Swelling volume and infarct growth volume were assessed using region-of-interest analysis on the baseline and follow-up DWI scans based on our prior methods. Results: Greater percentage of reperfusion was associated with less MLS (Spearman ρ = -0.46; P <0.0001) and reduced swelling volume (Spearman ρ = -0.56; P <0.0001). In multivariate analysis, reperfusion was an independent predictor of less MLS ( P <0.006) and decreased swelling volume ( P <0.0054), after adjusting for age, baseline NIHSS, admission blood glucose, baseline DWI volume, and IV tPA treatment. Conclusions: Reperfusion is associated with reduced brain edema as measured by MLS and swelling volume. While our data do not exclude the possibility of reperfusion edema in certain circumstances, in stroke patients, reperfusion following acute stroke is predominantly linked to less brain swelling.

Background: We have reported 5-year risk of stroke and vascular events after a transient ischemic attack (TIA) or minor ischemic stroke in patients enrolled into the TIAregistry.org, which was an international multicenter-cooperative, prospective registry (N Engl J Med 2018;378:2182-90). We conducted subanalysis on the 5-year follow-up data of Japanese patients in comparison with non-Japanese patients. Methods: The patients were classified into two groups on ethnicity, Japanese (n=345) and non-Japanese (n=3502), and their 5-year event rates were compared. We also determined predictors of five-year stroke in both groups. Results: Death from vascular cause (0.9% vs 2.7%, HR 0.28, 95% CI 0.09-0.89, p=0.031) and death from any cause (7.8% vs 9.9%, HR 0.67, 95% CI 0.45-0.99, p=0.045) were fewer in Japanese patients than in non-Japanese patients, while stroke (13.9% vs 7.2%, HR 1.78, 95% CI 1.31-2.43, p<0.001) and intracranial hemorrhage (3.2% vs 0.8%, HR 3.61. 95% CI 1.78-7.30, p<0.001) were more common in Japanese than non-Japanese patients during five-year follow-up period. Caplan-Meyer curves at five-years showed that the rates of stroke was also significantly higher in Japanese than non-Japanese patients (log-rank test, p=0.001). Predictors for stroke recurrence at five years were large artery atherosclerosis (HR 1.81, 95% CI 1.31-2.52, p<0.001), cardioembolism (HR 1.71, 95% CI 1.18-2.47, p=0.004), multiple acute infarction (HR 1.77, 95% CI 1.27-2.45, p<0.001) and ABCD 2 score 6 or 7 (HR 1.96, 95% CI 1.38-2.78, p<0.001) in non-Japanese patients, although only large artery atherosclerosis (HR 3.28, 95% CI 1.13-9.54, p=0.029) was a predictor for stroke recurrence in Japanese patients. Conclusions: Recurrence of stroke and intracranial hemorrhage were more prevalent in Japanese than non-Japanese patients. Large artery atherosclerosis was a predictor for stroke recurrence not only in non-Japanese patients but also in Japanese patients.

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Introduction: The effects of blood pressure (BP) reduction on clinical outcomes among acute stroke patient remain uncertain. Hypothesis: We tested the effects of immediate BP reduction on death and major disability at 14 days or hospital discharge and 3-month follow-up in acute ischemic stroke patients with and without a previous history of hypertension or use of antihypertensive medications. Methods: The China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) randomly assigned patients with ischemic stroke within 48 hours of onset and elevated systolic BP (SBP) to receive antihypertensive treatment (N=2,038) or to discontinue all antihypertensive medications (N=2,033) during hospitalization. Randomization was stratified by participating hospitals and use of antihypertensive medications. Study outcomes were assessed at 14 days or hospital discharge and 3-month post-treatment follow-up. The primary outcome was death and major disability (modified Rankin Scale score≥3), and secondary outcomes included recurrent stroke and vascular events. Results: Mean SBP was reduced 12.7% in the treatment group and 7.2% in the control group within 24 hours after randomization (P<0.001). Mean SBP was 137.3 mmHg in the treatment group and 146.5 in the control group at day 7 after randomization (P<0.001). At 14 days or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups by subgroups. At the 3-month follow-up, recurrent stroke was significantly reduced in the antihypertensive treatment group among patients with a history of hypertension (odds ratio 0.43, 95% CI 0.24-0.75, P=0.003) and among patients with a history of use of antihypertensive medications (odds ratio 0.41, 95% CI 0.20-0.84, P=0.01). All-cause mortality (odds ratio 2.84, 95% CI 1.11-7.27, P=0.03) was increased among patients without a history of hypertension. Conclusion: Immediate BP reduction lowers recurrent stroke among acute ischemic stroke patients with a previous history of hypertension or use of antihypertensive medications at 3 months. On the other hand, BP reduction increases all-cause mortality among patients without a history of hypertension.

   ASSOCIATION BETWEEN ALTERED HS-CRP LEVELS AND  COGNITIVE FUNCTION OF ISCHEMIC STROKE PATIENTSABSTRACTIntroduction: The incidence of cognitive impairment in acute ischemic stroke patients is increasing. The mechanism of the inflammatory effect, such as  elevated hs-CRP level, a  non-specific inflammatory marker  sensitive to chronic inflammation due to hypoperfusion as well other vascular risk, is thought to have an effect on cognitive function.Aims: To determine the relationship of cognitive function changes in acute phase of ischemic stroke with hs-CRP level changes on day 3 and day 7 after onset.Methods: This was a cross sectional study of 31 first-timer ischemic stroke patients who met inclusion and exclusion criteria. The level of hs-CRP was checked on the 3rd day and 7th day after onset, while MoCA-Ina was assessed on the 7th day after onset. Cognitive disturbance was considered if MoCA <26. Analyses was done using SPSS 2.0Results: The average onset of day 3 Hs-CRP concentration was 0.66 (0.12-16.67)mg/dl and the onset of day 7 was 5.455 (0.14-17.34)mg/dl. The mean change of hs-CRP level between 3 day and 7 day after onset was -0,16 (-3.32-4.95). There was a significant correlation between elevated hs-CRP levels on day 3 and day 7 after onset with cognitive function of acute ischemic stroke patients.Discussion: There was a significant correlation between elevated hs-CRP levels on day 3 and day 7 after onset with cognitive function of acute ischemic stroke patients.Keyword: Acute ischemic stroke, hs-CRP, MoCA-Ina scoresABSTRAKPendahuluan: Insidens penurunan fungsi kognitif pada pasien stroke iskemik akut semakin meningkat.
