Introduction. Etiology of acute ischemic stroke (AIS) is known to significantly influence management, prognosis, and risk of recurrence.Objective. To determine if ischemic stroke subtype based on TOAST criteria influences mortality.Methods. We conducted an observational study of a consecutive cohort of patients presenting with AIS to a single tertiary academic center.Results. The study population consisted of 500 patients who resided in the local county or the surrounding nine-county area. No patients were lost to followup. Two hundred and sixty one (52.2%) were male, and the mean age at presentation was 73.7 years (standard deviation, SD = 14.3). Subtypes were as follows: large artery atherosclerosis 97 (19.4%), cardioembolic 144 (28.8%), small vessel disease 75 (15%), other causes 19 (3.8%), and unknown 165 (33%). One hundred and sixty patients died: 69 within the first 30 days, 27 within 31–90 days, 29 within 91–365 days, and 35 after 1 year. Low 90-, 180-, and 360-day survival was seen in cardioembolic strokes (67.1%, 65.5%, and 58.2%, resp.), followed for cryptogenic strokes (78.0%, 75.3%, and 71.1%). Interestingly, when looking into the cryptogenic category, those with insufficient information to assign a stroke subtype had the lowest survival estimate (57.7% at 90 days, 56.1% at 180 days, and 51.2% at 1 year).Conclusion. Cardioembolic ischemic stroke subtype determined by TOAST criteria predicts long-term mortality, even after adjusting for age and stroke severity.

Although statins are established therapy for the secondary prevention of ischemic stroke, factors associated with adherence to statin treatment following ischemic stroke are not well known. To address this, we assessed the 6-month statin adherence using 8-item Morisky Medication Adherence Scale-8 in patients with acute ischemic stroke. Of 991 patients, 65.6% were adherent to statin at 6-month after discharge. Multiple logistic regression analysis showed that patients’ awareness of hyperlipidemia (OR 1.62; 95% CI 1.07–2.43), large artery stroke subtype (versus non-large artery stroke, OR 1.79; 95% CI 1.19–2.68), and alcohol drinking habits (OR 1.64; 95% CI 1.06–2.53) were positively associated, while high statin dose (versus low dose, OR 0.6; 95% CI 0.40–0.90) and higher daily number of medication pills (OR 0.93; 95% CI 0.88–0.97) were found to have a negative association with self-reported good adherence to statin medication after acute ischemic stroke. However, stroke severity and diagnosis of hyperlipidemia were not associated with adherence. These results suggest that educational and motivational interventions may enhance statin adherence because modifiable factors were associated with statin adherence.

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.

ObjectiveWe evaluated the association between admission HbA1c and subsequent risk of composite vascular events, including stroke, myocardial infarction, and vascular death, in patients with acute ischemic stroke and diabetes.MethodsPatients who had a transient ischemic attack or an acute ischemic stroke within 7 days of symptom onset, and diabetes were included in a retrospective cohort design using the stroke registry of the Clinical Research Center for Stroke in Korea. The association between admission HbA1c and composite vascular events, including stroke, myocardial infarction (MI), and vascular death, during one-year follow-up was estimated using the Fine-Gray model. The risk of composite vascular events according to the ischemic stroke subtype was explored using fractional polynomial and linear-quadratic models.ResultsOf the 18567 patients, 1437 developed composite vascular events during follow-up. In multivariable analysis using HbA1c as a categorical variable, the risk significantly increased at a threshold of 6.8%–7.0%. The influence of admission HbA1c level on the risk of composite vascular events was pronounced particularly among those in whom fasting glucose at admission was ≤130 mg/dL. The optimal ranges of the HbA1c associated with minimal risks for composite vascular events was the lowest for the small vessel occlusion subtype (6.6, [95% confidence internal [CI], 6.3–6.9]), compared to the large artery atherosclerosis (7.3 [95% CI, 6.8–7.9]) or the cardioembolic subtype (7.4[95% CI, 6.3–8.5]).ConclusionIn patients with ischemic stroke and diabetes, the risks of composite vascular events were significantly associated with admission HbA1c. The optimal range of the admission HbA1c was below 6.8%–7.0%, and were different according to the ischemic stroke subtype.

<b><i>Background:</i></b> The impact of gender on acute ischemic stroke, in terms of presentation, severity, etiology, and outcome, is increasingly getting recognized. Here, we analyzed the gender-related differences in etiology and outcome of ischemic stroke in South India. <b><i>Methods:</i></b> Patients with first ever ischemic stroke within 1 week of onset presenting to the Comprehensive Stroke Care Centre, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, India, were included in our study. Clinical and risk factor profile was documented. The stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS) at onset, and stroke subtype classification was done using Trial of Org 10172 in Acute Ischemic Stroke criteria. The 3-month functional outcome was assessed using the modified Rankin Scale (mRS) with excellent outcome defined as an mRS ≤2. <b><i>Results:</i></b> Of the 742 patients, 250 (33.7%) were females. The age, clinical profile, and rate of reperfusion therapies did not differ between the genders. Women suffered more severe strokes (mean NIHSS 9.5 vs. 8.4, <i>p</i> = 0.03). While large artery atherosclerosis was more common in men (21.3% vs. 14.8%, <i>p</i> = 0.03), cardioembolic strokes secondary to rheumatic heart disease were more common in women (27.2% vs. 19.7%, <i>p</i> = 0.02). Men had a better 3-month functional outcome compared to women (68.6% vs. 61.2%, <i>p</i> = 0.04), but was not statistically significant after adjusting for confounders. <b><i>Conclusion:</i></b> Our data, from a single comprehensive stroke unit from South India, suggest that stroke in women are different, yet similar in many ways to men. Guideline-based treatment can result in comparable short-term outcomes, irrespective of admission stroke severity.

Background: There is limited data about ischemic stroke in India. We characterized the clinical profile, risk factors and predictors of outcome after stroke in the Indian population, and investigated regional variations. Methods: The Indo-US Stroke Registry and Infrastructure Development Project, jointly funded by NINDS and the Indian Department of Biotechnology, currently includes 5 geographically diverse centers in North and South India and one in Boston, USA. Trained MD co-investigators and research coordinators prospectively collect data on consecutive adult patients with imaging-confirmed ischemic stroke <2 weeks after symptom onset. Data is entered into a central web-based electronic database. Results: From Nov-2012 to Jun-2013, 967 patients were enrolled. Mean age 59.7±13.9 yrs (range 20-92), 66% males. The patient population was 65% Hindu, 21% Sikh, 7% Christian, 6% Muslim, and 0.3% Jain; 58% had government health insurance. Only 3% arrived via EMS. Stroke risk factors included hypertension (66%), diabetes (39%), hyperlipidemia (20%), CAD (16%), atrial fibrillation (7.4%, rheumatic heart disease (5%). In addition to cigarette smoking (20%), exposure to beedi, hukkah, and smokeless tobacco (paan) was common (13%). The median admission NIHSS score was 9 (IQR, 5-15). Stroke subtypes using the automated ‘Causative Classification of Stroke’ program were large-artery atherosclerosis 31%, cardio-embolism 24%, small-vessel disease 15%, other defined causes 6%, and undetermined 24%. There were several regional differences, eg. hyperlipidemia, North 5% vs South 42% (p<0.001), good outcome (discharge mRS 0-2), North 45% vs South 57, p<0.001). Multivariate logistic regression analysis adjusting for age, gender and stroke severity showed that large artery atherosclerosis (OR 2.24, CI 2.18-2.37, p=0.02) and MCA territory strokes (OR 3.48, CI 2.02-3.67, p<0.0001) were predictors of poor outcome (mRS 3-6). Conclusions: The data provide insights about stroke in a large developing country. Resources are needed to address risk factors, regional differences, and develop the infrastructure for stroke care in India.

Introduction: Intravenous alteplase improves functional outcome in patients with acute ischemic stroke. While patients often have better outcomes, other patients may experience recurrent or worsening symptoms. We sought to determine the association between stroke subtype and neurologic deterioration in this study cohort. Methods: Data were abstracted from a prospective quality improvement registry at a comprehensive stroke center. Patients with symptomatic intracranial hemorrhage, no follow-up imaging, code status change to comfort measures only in the first 24 hours, or stroke mimics were excluded. Recurrent cerebrovascular events (RCVE) were defined as any new or worsening symptoms due to cerebral ischemia in the absence of intracranial hemorrhage or an alternative etiology such as infection or seizure. We compared demographic factors, vascular comorbidities, admission blood pressure, medications, use and timing of antithrombotics during hospitalization, admission NIH stroke scale, endovascular intervention, stroke subtype [Cardioembolic, large artery atherosclerosis, small vessel disease, cryptogenic, and other defined (such as dissection, hypercoagulability, cancer related, illicit drug use)], and good 90-day outcome (mRS 0-1) between the two groups using Fisher’s exact test and t-test as indicated. We then performed multivariable logistic regression analyses to determine associations between stroke subtypes and RCVE. Results: We identified 705 patients treated with tPA, and 606 met the inclusion criteria. The rate of RCVE was 5.8% (35/606). In multivariable analyses, when compared to cardioembolic/cryptogenic stroke, RCVE was more common in small vessel disease (adjusted OR 9.51 p=0.029), large vessel disease (adjusted OR 5.60, p=0.033), and other stroke mechanisms (adjusted OR 11.29, p=0.019). RCVE was associated with more disability at 90 days when compared to non-RCVE (median mRS 4, IQR 3 vs. median mRS 3, IQR 2, p = 0.016). Conclusions: Non-cryptogenic/Non-cardioembolic stroke subtypes are associated with early RCVE, and RCVE is associated with long term disability. Studies are needed to confirm our findings and test interventions optimizing stroke prevention strategies in these subtypes.

Introduction Systemic contraceptives increase the risk of ischemic stroke but little is known about the characteristics, mechanisms and long-term outcome post stroke of patients on hormonal contraception. We sought to To assess characteristics and outcome of acute ischemic stroke (AIS) in young women using systemic hormonal contraceptives (SHC) and compare them to strokes in non-contraceptive users. Patients and methods Using the Acute STroke Registry and Analysis of Lausanne (ASTRAL), we analyzed demographics, risk factors, clinical, radiological and treatment data of consecutive female patients of <50 years between 2003 to 2015. We compared groups with and without SHC in a logistic regression analysis. Results Of the 179 female patients of <50 years during the observation period, 57 (39.6%) used SHC, 71.9% of whom, a combined oral contraceptive pill. On logistic regression contraceptive users were significantly younger but had comparable stroke severity. They had less migraine with aura and tobacco use, and more hyperlipidaemia. Also, contraceptive users had significantly less intra and extracranial stenosis and occlusion on arterial imaging, but more focal hypoperfusion on CT-perfusion. Undetermined mechanism of stroke was more frequent with SHC users, whereas rare mechanisms were more frequent in non-users. The contraceptive user group had a more favourable adjusted 12-month outcome with significantly fewer ischemic recurrences after stopping systemic contraception in all. Conclusion Contraceptive users with ischemic strokes are younger and have lesser tobacco use and migraine with aura and more hyperlipidemia. Their stroke mechanism is more often undetermined using a standardised work-up, and their adjusted long-term outcome is more favourable with less stroke recurrence.

Background: Depicting the time trends of ischemic stroke subtypes may inform healthcare resource allocation on etiology-based stroke prevention and treatment. Aim: To reveal the evolving ischemic stroke subtypes from 2004 to 2018. Methods: We determined the stroke etiology of consecutive first-ever transient ischemic attack or ischemic stroke patients admitted to a regional hospital in Hong Kong from 2004 to 2018. We analyzed the age-standardized incidences and the 2-year recurrence rate of major ischemic stroke subtypes. Results: Among 6940 patients admitted from 2004 to 2018, age-standardized incidence of ischemic stroke declined from 187.0 to 127.4 per 100,000 population (p<0.001), driven by the decrease in large artery disease (43.0 to 9.67 per 100,000 population (p<0.001)) and small vessel disease (71.9 to 45.7 per 100,000 population (p<0.001)). Age-standardized incidence of cardioembolic stroke did not change significantly (p=0.2). Proportion of cardioembolic stroke increased from 20.4% in 2004-2006 to 29.3% in 2016-2018 (p<0.001). 2-year recurrence rate of intracranial atherothrombotic stroke reduced from 19.3% to 5.1% (p<0.001) with increased prescriptions of statin (p<0.001) and dual anti-platelet therapy (<0.001). In parallel with increased anticoagulation use across the study period (p<0.001), the 2-year recurrence of AF-related stroke reduced from 18.9% to 6% (p<0.001). Conclusion: Etiology-based risk factor control might have led to the diminishing stroke incidences related to atherosclerosis. To tackle the surge of AF-related strokes, arrhythmia screening, anticoagulation usage and mechanical thrombectomy service should be reinforced. Comparable preventive strategies might alleviate the enormous stroke burden in mainland China.

Abstract Introduction Global longitudinal strain (GLS) via speckle tracking echocardiography (STE) has emerged as a quantitative technique to estimate myocardial function and has been shown to have clinical utility in a variety of settings. The use of this technique in patients with a stroke is limited. Purpose Comparative analysis of myocardial deformation indicators in patients with a stroke, depending on the severity and subtype. Results 230 patients with an acute cerebrovascular accident (132 men and 98 women) were included in our study, with the mean age of 64,9±10,8. Transient ischemic attack (TIA) was diagnosed in 39 (17%), acute ischemic stroke (AIS) in 191 (83%) patients. The type of an ischemic stroke in each patient was classified as one of the following traditional stroke subtypes: large-artery atherosclerosis (LAA) was diagnosed in 85 (44,5%), cardioembolic infarcts were diagnosed in 58 (30,4%), lacunar infarcts were diagnosed in 32 (16,8%) and in 16 (8,4%) the stroke was of another determined or undetermined etiology. There was no significant difference in left ventricular (LV) ejection fraction (EF) between the subgroups of TIA and AIS - 63.0% [60.0; 65.0] and 62.0% [58.0; 65.0], respectively. The LV GLS was within normal limits and amounted to 19.9±2.6 in the TIA group where as in the group of patients with stroke there was a significant (p&lt;0.01) decrease in GLS below standard values - 17.1±3.8. The LV EF showed no significant difference between the groups of stroke subtypes. However, a decrease in GLS was found in the series from cardioembolic infarct &gt; lacunar infarct &gt; LAA - 17.5±3.7 &gt; 16.5±6.5 &gt; 16.2±3.2 (p=0,7). A decrease in GLS was significantly more often observed in male patients. A decrease in the level of GLS in patients with a stroke is associated with duration of type 2 diabetes, stroke severity by the National Institutes of Health Stroke Scale (NIHSS) score, ECG voltage criteria for LVH, increase in heart rate, LV mass/BSA, relative wall thickness (RWT) according to echocardiography. Significant differences in GLS from the size of the stroke focus according to CT scanning/ magnetic resonance imaging were not detected. Conclusion GLS via STE in patients with a stroke correlates with the severity of a stroke, the severity of LV remodeling, risk factors for cardiovascular events and requires a further study to assess the long-term prognosis Funding Acknowledgement Type of funding source: None
