Background: Previous studies have found that patients with TIA discharged from the emergency department (ED) have low rates of testing and treatment for secondary stroke prevention. Secondary Stroke Prevention Clinics (SPCs) were established in Ontario to increase access to diagnostics, treatment, and risk factor education programs for patients at risk of stroke. We aimed to characterize the management of patients with transient ischemic attack (TIA) and ischemic stroke referred to the SPCs following discharge from the ED. Method: The Ontario Stroke Registry performed a chart audit of 40 of 41 operational SPCs between April 1, 2011 and March 31, 2012. We included patients discharged from the ED and referred to a SPC with a diagnosis of probable stroke or TIA, and evaluated processes of best practice care. Using encrypted health card numbers, we linked to administrative databases to identify 7, 30 and 90 day outcomes after the index event. Results: Our study sample included 8,501 patients discharged from the ED and referred to a SPC with probable stroke/TIA. After evaluation in the SPC, 1,902 were given a final diagnosis of TIA and 1,126 ischemic stroke. The median age was 72 years and 46.6% were female. The median time from ED discharge to clinic visit was 8 days for TIA patients and 7 days for ischemic stroke patients. The majority of patients (>92%) received neuroimaging, carotid imaging and antithrombotic therapy, and rates of treatment were similar in those with TIA and stroke. The rate of death or recurrent stroke admission at 30 days was 3.6% among patients with confirmed ischemic stroke, and 0.4% in those with TIA. Conclusion: Ontario patients with TIA and ischemic stroke discharged from the ED with stroke secondary prevention clinic follow up receive high quality best practice secondary stroke prevention care. Further work will examine whether TIA patients discharged from EDs without SPC follow up have similar care and outcomes.

Introduction: Aspirin is one of the most commonly used medications for cardiovascular disease and stroke prevention. Many older patients who present with a first or recurrent stroke are already on aspirin monotherapy, yet little evidence is available to guide antithrombotic strategies for these patients. Method: Using data from the American Heart Association Get With The Guidelines-Stroke Registry, we described discharge antithrombotic treatment pattern among Medicare beneficiaries without atrial fibrillation who were discharged alive for acute ischemic stroke from 1734 hospitals in the United States between October 2012 and December 2017. Results: Of 261,634 ischemic stroke survivors, 100,016 (38.2%) were on prior aspirin monotherapy (median age 78 years; 53% women; 79.4% initial stroke and 20.6% recurrent stroke). The most common discharge antithrombotics (Figure) were 81 mg aspirin monotherapy (20.9%), 325 mg aspirin monotherapy (18.2%), clopidogrel monotherapy (17.8%), and dual antiplatelet therapy (DAPT) of 81 mg aspirin and clopidogrel (17.1%). Combined, aspirin monotherapy, clopidogrel monotherapy, and DAPT accounted for 86.8% of discharge antithrombotics. The rest of 13.2% were discharged on either aspirin/dipyridamole, warfarin or non-vitamin K antagonist oral anticoagulants with or without antiplatelet, or no antithrombotics at all. Among patients with documented stroke etiology (TOAST criteria), 81 mg aspirin monotherapy (21.2-24.0%) was the most commonly prescribed antithrombotic for secondary stroke prevention. The only exception was those with large-artery atherosclerosis, in which, 25.3% received DAPT of 81 mg aspirin and clopidogrel at discharge. Conclusion: Substantial variations exist in discharge antithrombotic therapy for secondary stroke prevention in ischemic stroke with prior aspirin failure. Future research is needed to identify best management strategies to care for this complex but common clinical scenario.

Background and Purpose Despite administration of evidence-based therapies, residual risk of stroke recurrence persists. This study aimed to evaluate the residual risk of recurrent stroke in acute ischemic stroke or transient ischemic attack (TIA) with adherence to guideline-based secondary stroke prevention and identify the risk factors of the residual risk.Methods Patients with acute ischemic stroke or TIA within 7 hours were enrolled from 169 hospitals in Third China National Stroke Registry (CNSR-III) in China. Adherence to guideline-based secondary stroke prevention was defined as persistently receiving all of the five secondary prevention medications (antithrombotic, antidiabetic and antihypertensive agents, statin and anticoagulants) during hospitalization, at discharge, at 3, 6, and 12 months if eligible. The primary outcome was a new stroke at 12 months.Results Among 9,022 included patients (median age 63.0 years and 31.7% female), 3,146 (34.9%) were identified as adherence to guideline-based secondary prevention. Of all, 864 (9.6%) patients had recurrent stroke at 12 months, and the residual risk in patients with adherence to guidelinebased secondary prevention was 8.3%. Compared with those without adherence, patients with adherence to guideline-based secondary prevention had lower rate of recurrent stroke (hazard ratio, 0.85; 95% confidence interval, 0.74 to 0.99; P=0.04) at 12 months. Female, history of stroke, interleukin-6 ≥5.63 ng/L, and relevant intracranial artery stenosis were independent risk factors of the residual risk.Conclusions There was still a substantial residual risk of 12-month recurrent stroke even in patients with persistent adherence to guideline-based secondary stroke prevention. Future research should focus on efforts to reduce the residual risk.

Stroke is cardiovascular disease that causes the world's highest disability and is the most prevalence disease after heart disease and cancer. Stroke is caused by circulatory disorders with 80% of the sufferers are diagnosed with ischemic stroke and 20% of them are diagnosed with hemorrhagic stroke. Patients who survive from the first stroke have high risk to have recurrent stroke. American Heart Association/American Stroke Association and Perhimpunan Dokter Spesialis Syaraf Indonesia recommend secondary stroke prevention therapy including antiplatelet/anticoagulant, antihypertensive agents, and antidislipidemia to minimalize the risk of recurrent stroke. Secondary stroke prevention therapy is only the first step. Patients need to be adhere to those therapies. The non-adherence will increase the risk of recurrent stroke. The study aimed to determine factors which causing the non-adherence to secondary prevention therapy in patients with ischemic stroke. This was a case control study with concecutive sampling method by interviewing patients who met the inclusion criterias i.e., had been diagnosed and were inpatients due to ischemic stroke, but in the time of interview patients were outpatients, patients were able to communicate and agree to participate in the study.Data was analized by bivariate / chi square test and multivariate logistic regression test. During the study period, 184 respondents met the inclusion criterias. Factors affecting non-adherence in the use of secondary prevention therapy were No one reminded to take medicine p = 0.03; OR 4.51, denial of the disease p = 0,036 OR 214, and tired of taking medicine p = 0,045 OR 1,97.

The Canadian Stroke Best Practice Consensus Statement: Secondary Stroke Prevention during Pregnancy, is the first of a two-part series devoted to stroke in pregnancy. This document focuses on unique aspects of secondary stroke prevention in a woman with a prior history of stroke or transient ischemic attack who is, or is planning to become, pregnant. Although stroke is relatively rare in this cohort, several aspects of pregnancy can increase stroke risk during or immediately after pregnancy. The rationale for the development of this consensus statement is based on the premise that stroke in this group requires a specifically-tailored management approach. No other broad-based, stroke-specific guidelines or consensus statements exist currently. Underpinning the development of this document was the concept that maternal health is vital for fetal wellbeing; therefore, management decisions should be based on the confluence of two clinical considerations: (a) decisions that would be made if the patient was not pregnant and (b) decisions that would be made if the patient had not had a stroke. While empirical research in this area is limited, this consensus document is based on the best available literature and guided by expert consensus. Issues addressed in this document include general management considerations for secondary stroke prevention, the use of antithrombotics, blood pressure management, lipid management, diabetes care, and management for specific ischemic stroke etiologies in pregnancy. The focus is on maternal and fetal health while minimizing risks of a recurrent stroke, through counseling, monitoring, and the safety of select pharmacotherapy. These statements are appropriate for health care professionals across all disciplines.

Background: Polyvascular disease (PolyVD) and interleukin (IL)-6 are associated with poor outcomes in patients with stroke respectively. However, whether combined PolyVD and elevated IL-6 levels would increase the risk of poor outcomes of stroke patients is yet unclear.Methods: Data were obtained from the Third China National Stroke Registry (CNSR-III). PolyVD was defined as acute ischemic stroke (AIS) or transient ischemic attack (TIA) with coronary artery disease (CAD) and/or peripheral artery disease (PAD). Patients were divided into four groups according to the combination of vascular beds number (non-PolyVD or PolyVD) and IL-6 levels (IL-6 < 2.64 pg/mL or IL-6 ≥ 2.64 pg/mL). The primary outcome was a recurrent stroke at 1-year follow-up. Cox proportional hazard models were employed to identify the association of the combined effect of PolyVD and IL-6 with the prognosis of patients.Results: A total of 10,773 patients with IL-6 levels and 1-year follow-up were included. The cumulative incidence of recurrent stroke was 9.87% during the 1-year follow-up. Compared to non-PolyVD and IL-6<2.64 pg/mL patients, patients had non-PolyVD with IL-6 ≥ 2.64 pg/mL (HR 1.245 95%CI 1.072–1.446; P < 0.001) and PolyVD with IL-6 <2.64 pg/mL (HR 1.251 95%CI 1.002–1.563; P = 0.04) were associated with an increased risk of recurrent stroke during 1-year follow-up. Likewise, patients with PolyVD and IL-6 ≥ 2.64 pg/mL (HR 1.290; 95% CI 1.058–1.572; P = 0.01) had the highest risk of recurrent stroke at 1-year follow-up among groups.Conclusion: PolyVD and elevated IL-6 levels are both associated with poor outcomes in patients with AIS or TIA. Moreover, the combination of them increases the efficiency of stroke risk stratification compared with when used alone. More attention and intensive treatment should be given to those patients with both PolyVD and elevated IL-6 levels.

Abstract Purpose The study aimed to identify echocardiographic, hemodynamic and biochemical predictors of unfavourable prognosis after ischemic strokes of undetermined etiology (ESUS) in patients (pts) at age <65. Methods Out of 520 ischemic stroke pts we selected 64 pts diagnosed with ESUS [mean age 54 (SD: 47–58) years, 42% males] and additional 36 without stroke but with similar risk profile, which were treated as a reference group [age 53 (SD: 47–58) years, 61% males]. All pts underwent echocardiography, non-invasive assessment of hemodynamic parameters using SphygmoCor tonometer (Atcor Med., Australia), HDL subfraction distribution using Lipoprint (Quantimetrix) as well as measurements of selected biomarkers. Follow-up was 12 months. Results At 12-month follow-up 9% of patients had died, and recurrent ischemic stroke also occurred in 9% of patients - only in the ESUS group (Figure). Patients who died had significantly lower levels of LDL and HDL cholesterol (included HDL-8 and -9 subfractions) and higher level of triglicerides (p=0.01, p=0.01, and p=0.02; respectively), lower level of adiponectin (p=0.01), lower value of mean early diastolic (E') mitral annular velocity (p=0.04) and lower diastolic blood pressure (p=0.04). The atrial fibrillation (AF) occurred in 10% of pts during the 12 months (log-rang, p=0.254) (Figure). The log-rank test showed that ESUS group had a significantly poorer outcome of AF in the first 2 months after hospitalization compared to reference group (11% vs 5%, p=0.041). Based on a Kaplan-Meier analysis, the outcome of re-hospitalizationin the 1st year was 28% (18/64) in the ESUS group and 17% (6/36); log-rank, p=0.058. In the multivariate analysis mean early diastolic (E') mitral annular velocity (odds ratio [OR] 0.75, 95% confidence interval [CI]: 0.6–0.94; p=0.01) was significantly associated with CV hospitalizations assessed at 12-month follow-up. The only independent predictor of AF occurrence in the 12-month follow-up was lower value of Tissue Doppler-derived right ventricular systolic excursion velocity S' (OR 0.65, 95% Cl 0.45–0.93; p=0.01). The only independent predictor of recurrent stroke was the ratio of peak velocity of early diastolic transmitral flow to peak velocity of early diastolic mitral annular motion as determined by pulsed wave Doppler (E/E') (OR 0.75, 95% CI: 0.6–0.94; p=0.01). E/E' ratio was also independently associated with composite endpoint consisting of death, hospitalization and recurrent stroke (OR 1.90, 95% CI 1.1–3.2, p=0.01). Kaplan-Meier Analysis - survival and AF Conclusions The indices of diastolic dysfunction are significantly associated with unfavourable prognosis after ESUS. There is a robust role for outpatient cardiac monitoring especially during first 2 months after ESUS to detect potential AF.

Purpose: To investigate the incidence and clinical characteristics of recurrent stroke beyond 30 days after uncomplicated angioplasty and stenting for symptomatic intracranial stenosis. Methods: Primary endpoints in SAMMPRIS (Stenting and Aggressive Medical Management for the Prevention of Recurrent Ischemic Stroke) after 30 days past enrollment were defined as ischemic stroke in the territory or any stroke or death within 30 days of a subsequent revascularization procedure. Endpoints were independently and blindly adjudicated. Study records and imaging studies of subjects randomized to the stent arm with post-30 day primary endpoints were reviewed. Instent restenosis (ISR) was categorized as severe (>70%), moderate (50-69%) or mild (< 50%) based on consensus of two reviewers. Findings were categorized as definite, probable, or indeterminate based on imaging modality and study quality. Results: 224 subjects were randomized to the stent arm and 33 suffered a primary endpoint within 30 days of enrollment. Nineteen of the remaining 191 subjects (9.9%) suffered a primary endpoint during follow up (median follow up of 32.4 months). Eighteen had an ischemic stroke in the territory and one had a symptomatic intracranial hemorrhage after repeat angioplasty for in stent restenosis (ISR). In the 18 patients with ischemic stroke, the vascular imaging findings were: complete stent occlusion in 2 (1 of these was acutely revascularized and severe underlying ISR was identified), severe ISR by catheter angiography in 5, severe ISR or occlusion by computed tomographic angiography (CTA) in 1, probable ISR by CTA or magnetic resonance angiography (MRA) in 3, moderate stenosis on angiography in 2 (1 with ISR and 1 with a residual stenosis), indeterminate in 2, normal in 2, and not done in 1. Lesion locations included: distal internal carotid (6), petrous carotid (1), basilar (5), middle cerebral (6), and vertebral (1) arteries. Median time to recurrent stroke was 7.7 months from enrollment (2.2 to 28.2 months). Conclusions: The incidence of recurrent stroke beyond 30 days after uncomplicated angioplasty and stenting in the SAMMPRIS trial was nearly 10% over a mean follow-up of almost 3 years. In stent restenosis was associated with the majority of recurrent strokes.

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.

The 2018 update of the Canadian Stroke Best Practice Recommendations for Acute Stroke Management, 6th edition, is a comprehensive summary of current evidence-based recommendations, appropriate for use by healthcare providers and system planners caring for persons with very recent symptoms of acute stroke or transient ischemic attack. The recommendations are intended for use by a interdisciplinary team of clinicians across a wide range of settings and highlight key elements involved in prehospital and Emergency Department care, acute treatments for ischemic stroke, and acute inpatient care. The most notable changes included in this 6th edition are the renaming of the module and its integration of the formerly separate modules on prehospital and emergency care and acute inpatient stroke care. The new module, Acute Stroke Management: Prehospital, Emergency Department, and Acute Inpatient Stroke Care is now a single, comprehensive module addressing the most important aspects of acute stroke care delivery. Other notable changes include the removal of two sections related to the emergency management of intracerebral hemorrhage and subarachnoid hemorrhage. These topics are covered in a new, dedicated module, to be released later this year. The most significant recommendation updates are for neuroimaging; the extension of the time window for endovascular thrombectomy treatment out to 24 h; considerations for treating a highly selected group of people with stroke of unknown time of onset; and recommendations for dual antiplatelet therapy for a limited duration after acute minor ischemic stroke and transient ischemic attack. This module also emphasizes the need for increased public and healthcare provider’s recognition of the signs of stroke and immediate actions to take; the important expanding role of paramedics and all emergency medical services personnel; arriving at a stroke-enabled Emergency Department without delay; and launching local healthcare institution code stroke protocols. Revisions have also been made to the recommendations for the triage and assessment of risk of recurrent stroke after transient ischemic attack/minor stroke and suggested urgency levels for investigations and initiation of management strategies. The goal of this updated guideline is to optimize stroke care across Canada, by reducing practice variations and reducing the gap between current knowledge and clinical practice.
