Abstract TMP110: Antithrombotic Therapy and Risk of Stroke Recurrence in Children With Congenital and Acquired Cardiac Disease

Background: Antithrombotic therapy (ATT) is currently recommended for stroke prevention in pediatric cardioembolic arterial ischemic stroke (CE-AIS) where the risk of recurrence is high. Methods: We conducted a retrospective study of a prospectively enrolled cohort of neonates and children with radiologically-confirmed cardioembolic arterial ischemic stroke (CE-AIS) from January 2003 - December 2017. We evaluated the clinical and radiographic predictors of hemorrhagic transformation (HT) and stroke recurrence to assess the safety and efficacy of ATT. Results: Eighty-two children met inclusion criteria [53.7% males and 28% neonates; median age 0.43 (IQR: 0.08 - 4.23) years]. Stroke recurred in 11 children at a median of 32 days (IQR: 5.5 - 93) from the index event. Most recurrent infarcts were silent (n=6; 54.5%) and found on follow-up neuroimaging with an average follow-up interval of 4.1 ±3 .5 years. Procedure-related recurrence took place in 1 (9.1%) child. Ten (90.9%) children were receiving antithrombotic therapy at the time of recurrence: 8 (72.7%) were on anticoagulant therapy (ACT) and 2 (18.2%) were on a combination of antiplatelet (ATP) and ACT. HT occurred in 20 of 82 children (24.4%), all of whom were receiving ACT, 5 (6.1%) of whom were symptomatic. Four (4.9%) had systemic hemorrhage. There was no difference in the frequency of stroke recurrence between those with and without HT [3 (15.0%) vs. 8 (12.9%); p=1.00]. Children with univentricular physiology were less likely to have HT [15% vs. 43.5%; p=0.03] and had higher rates of recurrent stroke, prior to definitive cardiac repair, despite receiving ATT. Stroke recurrence was highest in those with cyanotic congenital heart disease (CHD) pre-surgery (3/11), cyanotic CHD post-palliative surgery with residual right-to-left-shunt (3/11) and in those with cardiomyopathy (4/11). HT was not associated with ATP vs. ACT use nor combination therapy. Conclusion: ATT appears to be relatively safe in children with CE-AIS. However, ATT warrants further optimization to prevent stroke recurrence, particularly in those with single ventricle physiology and reduced left ventricular function.

Vessel Infiltration

Introduction: The incidence of stroke is higher in patients with malignancy, especially within a few months of diagnosis and in more aggressive cancers. This phenomenon may be explained by an inherent hypercoagulable state, tumor embolism, vessel infiltration, or as a side effect from cancer treatment. Notably, stroke in cancer patients is associated with poor functional outcomes and reduced survival. Currently, however, there are no clear guidelines for antithrombotic management for prevention of recurrent strokes in these patients. Methods: We conducted a single-center retrospective chart review from 2013-2019. All adult patients with an ischemic stroke occurring with active malignancy and who then received either a direct oral anticoagulant (DOAC) or low molecular weight heparin (LMWH) were included. Patients with hemorrhagic stroke, an intracranial malignancy, or who were immediately admitted to hospice were excluded. Results: A total of 55 patients were included with a mean age of 71.8 years (range 28-96), 60% females, 87.3% first-time strokes, and 54.9% with metastatic disease. After stroke, 25 patients received a DOAC and 30 received LMWH for anticoagulation with a mean follow-up of 403 days. Between these two groups, most presentation and treatment characteristics were similar except for baseline hypertension, hyperlipidemia, additional initiation of an antiplatelet, and follow-up time. There was no difference in either stroke recurrence (DOAC vs LMWH: OR 2.61 [0.51-13.45], p=0.252) or time to recurrent stroke (DOAC vs LMWH: HR 1.68, p=0.446), but both analyses required adjustment for additional initiation of an antiplatelet—which was significantly protective regardless of anticoagulation choice (p=0.021* and p=0.017*, respectively). There was a trend towards improved survival if placed on a DOAC (HR 0.27, p=0.051), even after adjusting for metastatic disease. Conclusions: In this initial study of cancer patients with ischemic stroke, anticoagulation choice made no difference on stroke recurrence; however, addition of an antiplatelet agent was significantly protective. There was also a trend towards improved survival on a DOAC. Additional prospective data incorporating a larger sample size could further validate these findings.

Background: A major cause of ischemic stroke (IS) worldwide, especially in Asia, is intracranial atherosclerotic stenosis (ICAS), which is also associated with the high risk of recurrent stroke. Objective: The aim of our study was to determine the natural history of symptomatic ICAS ischemic stroke (ICAS IS) patients. Materials and Methods: We collected data on acute ICAS IS patients beyond the hyperacute IS phase to determine stroke recurrence and mortality at a tertiary care neurology hospital. Data were collected on basic demographics and traditional risk factors such as hypertension, coronary artery disease, diabetes mellitus, tobacco abuse, and hyperlipidemia, and statistical analysis was done. The primary endpoint was to measure the unfavorable outcome as defined by recurrent stroke or death from any cause. Results: The mean follow-up time for the total 87 patients was 24.5 months. Nine patients (10.3%) had an unfavorable outcome in the follow-up period; 2 (2.3%) of them had recurrent IS. Age was a predictor of the unfavorable outcome ( P = .0025), whereas hyperlipidemia was present more in patients with the favorable outcome ( P = .033). There was a tendency for patients with poor outcomes to have a higher National Institutes of Health Stroke Scale at their onset of stroke. Conclusions: Aggressive medical treatment was associated with a relatively low risk of recurrent stroke in our ICAS IS population. This study provides groundwork for larger studies that can take into account clinical and newer imaging techniques to improve secondary prevention in ICAS IS patients.

Background and Purpose— Emboli in embolic stroke of undetermined source (ESUS) may originate from various potential embolic sources (PES), some of which may respond better to anticoagulation, whereas others to antiplatelets. We analyzed whether rivaroxaban is associated with reduction of recurrent stroke compared with aspirin in patients with ESUS across different PES and by number of PES. Methods— We assessed the presence/absence of each PES (atrial cardiopathy, atrial fibrillation, arterial atherosclerosis, left ventricular dysfunction, cardiac valvulopathy, patent foramen ovale, cancer) in NAVIGATE-ESUS (New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source) participants. Prevalence of each PES, as well as treatment effect and risk of event for each PES were determined. Results by number of PES were also determined. The outcomes were ischemic stroke, all-cause mortality, cardiovascular mortality, and myocardial infarction. Results— In 7213 patients (38% women, mean age 67years) followed for a median of 11 months, the 3 most prevalent PES were atrial cardiopathy (37%), left ventricular disease (36%), and arterial atherosclerosis (29%). Forty-one percent of all patients had multiple PES, with 15% having ≥3 PES. None or a single PES was present in 23% and 36%, respectively. Recurrent ischemic stroke risk was similar for rivaroxaban- and aspirin-assigned patients for each PES, except for those with cardiac valvular disease which was marginally higher in rivaroxaban-assigned patients (hazard ratio, 1.8 [95% CI, 1.0–3.0]). All-cause mortality risks were similar across treatment groups for each PES while too few myocardial infarctions and cardiovascular deaths occurred for meaningful assessment. Increasing number of PES was not associated with increased stroke recurrence nor all-cause mortality, and outcomes did not vary between rivaroxaban- and aspirin-assigned patients by number of PES. Conclusions— A large proportion of patients with ESUS had multiple PES which could explain the neutral results of NAVIGATE-ESUS. Recurrence rates between rivaroxaban- and aspirin-assigned patients were similar across the spectrum of PES. Registration— URL: https://www.clinicaltrials.gov ; Unique identifier: NCT02313909.

BackgroundNew-onset headache after stroke is common among adult stroke survivors. However, pediatric data are limited. The primary aim of this study was to investigate the prevalence of new-headache after pediatric ischemic stroke. Secondary outcomes were to describe the characteristics of patients experiencing poststroke headache and the association between poststroke headache and stroke recurrence.MethodsWe conducted a single-center retrospective study on children aged 30 days to 18 years with a confirmed radiographic diagnosis of arterial ischemic stroke (AIS) from January 1, 2008, to December 31, 2016. Patients were identified from an internal database, with additional data abstracted from the electronic medical record. Poststroke headache (occurring >30 days after stroke) was identified through electronic searches of the medical record and confirmed by chart review.ResultsOf 115 patients with confirmed AIS, 41 (36%) experienced poststroke headache, with headache developing a median of 6 months after stroke. Fifty-one percent of patients with poststroke headache presented to the emergency department for headache evaluation; 81% of the patients had an inpatient admission for headache. Older age at stroke (odds ratio [OR] 21.5; p = 0.0001) and arteriopathy (OR 8.65; p = 0.0029) were associated with development of poststroke headache in a multivariable analysis. Seventeen patients (15%) had a recurrent stroke during the study period. Poststroke headache was associated with greater risk for stroke recurrence (p = 0.049).ConclusionsRemote poststroke headache is a common morbidity among pediatric stroke survivors, particularly in older children. Headaches may increase health care utilization, including neuroimaging and hospital admissions. We identified a possible association between poststroke headache and stroke recurrence.

Introduction: Head and neck vasculopathies are the most frequent identifiable cause of childhood arterial ischemic stroke, and abnormal vascular imaging is associated with higher risk of stroke recurrence. Despite this, little is known about how vasculopathy subtype impacts risk of both initial and recurrent stroke. In this single-center retrospective analysis, we analyze differences in stroke recurrence by vasculopathy subtype. Methods: Using ICD codes, we identified children treated for a head or neck vasculopathy at our tertiary care center between 2003 and 2019. Inclusion criteria included imaging-confirmed head or neck vasculopathy diagnosed between the ages of 28 days and 18 years. Retrospective chart review was carried out with attention to vasculopathy subtype and occurrence/recurrence of stroke and TIA. Results: Ninety-three patient met inclusion criteria, including 55 who experienced a stroke. Five-year stroke recurrence rates differed significantly by vasculopathy subtype (n=28, p=0.030, Fisher exact test), as patients with moyamoya disease (MMD) and sickle cell, Down syndrome, or neurofibromatosis-related vasculopathy experienced higher recurrence rates. There was a non-significant increased rate of stroke recurrence among patients with secondary versus primary MMD. Conclusions: Children with primary and secondary MMD have a higher risk of stroke recurrence than children with other vasculopathy subtypes. Further studies are needed to evaluate the effect of vasculopathy etiology and other radiographic and clinical characteristics on stroke recurrence risk so that appropriate treatment strategies can be implemented early in these high-risk patients.

Patient Case

Introduction : Case report: 63 year old African American woman with history of hypertension presented with acute onset of expressive aphasia. Her neurologic exam and NIHSS was significant for moderate aphasia with paraphasic errors and impairment of repetition. She was outside the treatment window for IV thrombolytic therapy. CT angiography of the head and neck in the ED showed moderate 60–70% stenosis of the left internal carotid artery secondary to a carotid web. She was admitted to the stroke service and started on DAPT with ASA and clopidogrel. MRI brain was obtained, which confirmed a small acute infarct in the posterior margin of the left sylvian fissure. Methods : Intervention and Follow‐up: Vascular surgery and interventional neurology were consulted to discuss the treatment options for the patient’s carotid web. Give the unique nature of the patient’s web with its triple lumen appearance, carotid endarterectomy (CEA) was favored over stenting, and the patient underwent left CEA. There were no immediate complications, and she was continued on DAPT for 21 days, then ASA monotherapy. One month follow‐up carotid dopplers of the left ICA showed patent flow without significant stenosis. On follow‐up evaluations at 3 and 12 months, the patient’s speech deficits had improved significantly and she reported no new stroke‐like symptoms. Results : Literature Review: Carotid webs (CaW) may be a potentially underrecognized cause of ischemic strokes. CaW are thin, fibrous tissue that extends from the wall of the carotid artery into the lumen in a shelf‐like projection. It is believed to be a variant of fibromuscular dysplasia. It is hypothesized that blood stasis on the downstream surface of the web may result in thrombus formation and thromboembolic stroke. The optimal treatment for CaW remains unclear, however there is some evidence to suggest that antiplatelet therapy alone may be insufficient to prevent recurrent stroke, with rates of recurrent stroke of 30–50% from a systematic literature review. Furthermore, there have been no reports of CaW positive remodeling over time, so patients likely remain at elevated risk for ischemic stroke without intervention. Conclusions : Discussion: Case series as well as systematic literature review have shown high rates of stroke recurrence in CaW patients treated with medical therapy alone. Data is still limited, however, CEA and carotid artery stenting (CAS) appear to be safe and effective revascularization procedures for CaW, with potentially significant reduction in recurrent stroke risk. CEA was preferred in our patient case due to the triple‐lumen appearance of the carotid web (Figure). CaW is a relatively underappreciated cause of ischemic strokes and the optimal management is not well‐established, however medical therapy alone appears to be sub‐optimal with high rates of stroke recurrence. Our patient case shows that carotid revascularization can be safe may be effective in preventing stroke recurrence.

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.

Abstract Background Left ventricular mechanical dyssynchrony (LVMD) is a predictor of many cardiovascular outcomes including ventricular arrhythmias. However, the prognostic value of LVMD in predicting incident atrial fibrillation (AF) in participants from the general population is currently unknown. Purpose The aim of this study was to investigate if LVMD can be used to predict AF and ischemic stroke in the general population. Methods A total of 1282 participants (mean age 57±16 years, 42% male) from the general population underwent a health examination including two-dimensional speckle tracking echocardiography. LVMD was calculated as the standard deviation of the regional time-to-peak strain from the three apical views. The primary endpoint was incident AF at follow-up. All participants with known AF and prior stroke at baseline were excluded (n=84). The secondary endpoint consisted of the composite of AF and ischemic stroke. Results During a median follow-up of 16 years, 148 participants (12%) were diagnosed with incident AF and 88 (7%) experienced an ischemic stroke, resulting in 236 (19%) experiencing the composite outcome. The risk of AF increased incrementally with increasing tertile of LVMD, being approximately 2-fold higher in the 3rd tertile as compared to the 1st tertile (HR 1.79; 95% CI (1.22–2.63), p=0.003; figure). LVMD was a univariable predictor of AF with 7% increased risk per 10ms increase in LVMD (per 10ms: HR 1.07; 95% CI (1.03–1.12), p<0.001). The association remained significant even after multivariable adjustment for age, sex, body mass index, hypertension, diabetes, previous ischemic heart disease, systolic blood pressure, diastolic blood pressure, heart rate, smoking, plasma proBNP, left ventricular ejection fraction <50%, global longitudinal strain, left atrial volume index (LAVI) and E/e' (per 10ms increase: HR 1.06; 95% CI (1.01–1.12), p=0.018). LVMD was also a univariable predictor of the composite outcome of AF and ischemic stroke (per 10ms increase: HR 1.07; 95% CI (1.04–1.11), p<0.001). After multivariable adjustment for the same clinical and echocardiographic parameters, LVMD remained an independent predictor of the composite outcome (per 10ms: HR 1.07; 95% CI (1.03–1.11), p=0.001). Additionally, LVMD provided incremental prognostic information with regard to predicting AF as assessed by a significant increase in the net reclassification improvement (NRI) index beyond the CHARGE-AF score (continuous NRI, 0.300; 95% CI, 0.022–0.503). Furthermore, LVMD provided additional incremental prognostic information, when added to both the CHARGE-AF score and the LAVI (continuous NRI, 0.269; 95% CI, 0.004–0.499). Conclusion In a low risk general population, LVMD provides novel prognostic information on the long-term risk of AF and ischemic stroke. In addition, LVMD provides incremental prognostic information beyond the CHARGE-AF score and LAVI in predicting AF in the general population. Funding Acknowledgement Type of funding source: None

The Relationship

AbstractThe relationship between exercise and stroke recurrence is controversial. This study was designed to test whether an association exists between exercise and ischemic stroke recurrence in first-ever ischemic stroke survivors. Data were collected from January 2010 to June 2016. Baseline information was obtained during face-to-face interviews, and follow-up phone interviews were conducted every 3 months. Exercise type, frequency, intensity, and duration were recorded. Discrete-time survival analysis was used to determine the relationship between exercise and stroke recurrence. 760 first-ever ischemic stroke survivors who were able to exercise were enrolled. After adjusting for covariates, patients who exercised 3.5–7 h per week and more than 7 h per week had a lower relapse risk than patients who did not exercise (3.5–7: OR 0.415; > 7: OR 0.356). Moreover, if the fluctuation of exercise duration was over 4 h, the patients had a higher risk of stroke recurrence than those with variability of less than 2 h (OR 2.153, P = 0.013). Stroke survivors who engage in long-term regular mild exercise (more than 5 sessions per week and lasting on average 40 min per session) have a lower recurrence rate. Irregular exercise increases the risk of stroke recurrence.

Ischemic stroke and transient ischemic attack (TIA) are the most common cerebrovascular disorder and leading cause of death in China. The Effective secondary prevention is the vital strategy for reducing stroke recurrence. The aim of this guideline is to provide the most updated evidence-based recommendation to clinical physicians from the prior version. Control of risk factors, intervention for vascular stenosis/occlusion, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke are all recommended, and the prevention of recurrent stroke in a variety of uncommon causes and subtype provided as well. We modified the level of evidence and recommendation according to part of results from domestic RCT in order to facility the clinical practice.
