Stroke, Volume 53, Issue Suppl_1, Page AWP209-AWP209, February 1, 2022. Background:The optimal timing for the initiation of anticoagulation in patients with acute ischemic stroke (AIS) related to atrial fibrillation (AF) remains uncertain. Observational studies assessing early anticoagulant initiation (≤14 days after index AIS) have provided conflicting results from the early use of non-vitamin K oral anticoagulants (NOACs) or vitamin K antagonists (VKAs).Methods:We performed a meta-analysis of prospective observational studies and RCTs to assess the efficacy and safety of early anticoagulation in AF-related AIS. We also compared the efficacy and safety between NOAC and VKA regimens. A random-effects model was used to pool the individual risk ratios (RRs) and corresponding 95% confidence intervals (CIs) between the two groups. Recurrent ischemic stroke was defined as the primary outcome.Results:Nine eligible studies (7 observational, 2 RCTs) were identified, including 6,840 patients with AF-related AIS (pooled mean baseline NIHSS score: 5.5; 95%CI: 3.7-7.2) who received early anticoagulation. The overall ischemic stroke recurrence rate was 5% (95%CI: 3.3-7%) and differed (p=0.05) between studies reporting anticoagulation initiation within a week (2.5%, 95%CI: 0.2-7.4%) or two weeks (6.7%, 95%CI:4.6-9.1%) from index event. The corresponding proportions of patients experiencing a fatal outcome, symptomatic or asymptomatic ICH were 4% (95%CI: 1.6-7.5%), 1.2% (95%CI: 0.3-2.6%) and 13.2% (95%CI: 6.4-22.1%), respectively. Of the 2 identified RCTs, 136 and 135 patients were randomized to early anticoagulation with NOAC or VKA, respectively. Both groups had a similar risk for ischemic stroke recurrence (RR=0.78; 95%CI: 0.32, 1.91; p=0.59). No significant differences were uncovered between early NOAC or early VKA treatment initiation for the outcomes of mortality (RR=0.57; 95%CI: 0.11, 2.97; p=0.51), symptomatic ICH (RR=0.38; 95%CI: 0.02, 9.10; p=0.55) or asymptomatic ICH (RR=1.10; 95%CI: 0.73, 1.67; p=0.64).Conclusions:Preliminary evidence from RCTs on early anticoagulation after AF-related AIS suggest that NOACs have comparable efficacy to VKAs in preventing ischemic stroke recurrence. Large scale RCTs are warranted to evaluate the potential superiority of NOACs in terms of safety endpoints.

Stroke, Volume 53, Issue Suppl_1, Page AWMP73-AWMP73, February 1, 2022. Background and Purpose:Cardiac surgery is indicated in more than half of patients with infective endocarditis (IE); however, it is performed in only 60% of the indicated cases. Majority of patients with surgical indications who were denied surgery due to certain reasons die within 30 days. Intracranial hemorrhage (ICH) is one of the main causes for denial of surgery despite the presence of surgical indications. We aimed to evaluate the impact of early surgery (within 30 days) in IE-patients with ICH on postoperative outcome and to elucidate the risk of 30-day mortality in patients for whom surgery was denied.Methods:Three libraries (MEDLINE, EMBASE and Cochrane Library) were assessed for studies evaluating the postoperative outcome in early vs. late surgery in IE-patients with preoperative ICH. The primary outcome was all-cause mortality, and the secondary outcome was neurological deterioration. Inverse variance method and random model were performed.Results:We identified 16 studies including 355 patients. Nine studies examined the impact of surgical timing (early vs. late) and were included in the meta-analyses. Only one study examined the fate of IE-patients with ICH who were treated conservatively despite of having an indication for cardiac surgery, showing higher mortality rates than those who were operated (11.8 % vs. 2.5 %). We found no significant association between early surgery, regardless of its definition, and a higher mortality (relative risk [RR]= 1.46; 95% confidence interval [CI]: 0.98-2.17). However, early surgery was associated with higher risk for neurological deterioration (RR= 1.97; 95% CI: 1.15-3.38).Conclusions:Cardiac surgery for IE within 30 days of ICH was not associated with higher mortality, but with increased rate of neurological deterioration. Thirty-day mortality in IE-patients with ICH for whom surgery was denied has not yet been sufficiently investigated. This patient group should be analysed in future studies in more detail.

Stroke, Volume 53, Issue Suppl_1, Page ATP208-ATP208, February 1, 2022. Introduction:Hypertrophic cardiomyopathy (HCM) predisposes to adverse cerebrovascular events (ACEs) including ischaemic stroke, transient ischaemic attack (TIA), thromboembolic event (TEE) and peripheral embolism (PE). Concomitant atrial fibrillation (AF), which is more prevalent in the HCM population, confers even higher risk. Our aims are to report the prevalence of ACEs in HCM patients and to determine the additional clinical risks of AF on the prognosis of this population.Methods:A systematic literature search was performed on PubMed, Scopus, Embase/ Ovid and Cochrane library from inception to 20thMarch 2021. No limitations on language or date of publication were applied. The primary outcome of this review was to examine and compare the prevalence of ischaemic stroke in the HCM population with or without AF. Secondary outcomes were to identify their risk of non-stroke clinical outcomes such as TIA, non-specified TEE and PE. Non-specified TEE in our paper only referred to thromboembolic events whereby their types were not specified in the included studies. Meta-analysis was performed using StataSE 16 software, and heterogeneity was assessed usingI2test.Results:A total of 713 studies were identified, and 35 articles with 42,570 patients were included. The pooled prevalence of stroke/ TIA was 7.45% (95% confidence interval [CI] 5.80 – 9.52,p= 0.000) across 24 studies in the overall HCM population of 37,643 patients. AF contributed to a significantly higher risk of non-specified TEE (Risk ratio [RR] 4.49, 95% CI 1.88 – 10.73,p= 0.0007,I2= 87.0) and total stroke/ TIA (RR 3.26, 95% CI 1.75 – 6.08,p= 0.0002,I2= 76.0) in our study population. Within the apical HCM (ApHCM) population, the prevalence of stroke/ TIA was 9.30% (95% CI 6.64 – 12.87,p= 0.316).Conclusion:Our study concludes that concomitant AF diagnosis increases the risk of developing thromboembolic events and the stroke-related mortality rate. Although the prevalence of stroke/ TIA in the ApHCM subtype was slightly higher than the overall HCM population, further studies investigating the clinical outcomes of HCM subtypes are warranted.

Stroke, Volume 53, Issue Suppl_1, Page A135-A135, February 1, 2022. Background:Endovascular thrombectomy is the gold standard treatment for acute ischemic strokes with large vessel occlusions (LVO). Manual image analysis is often time consuming and requires clinicians to be skilled in reading perfusion scans, as well as vessel images. RapidAI software has an automated processor to detect LVO of the middle cerebral artery and is analyzed in this study. A novel metric, number-needed-to-review (NNR), is introduced to assess the clinical efficiency of this software.Methods:This is a retrospective review of patients with a suspected ischemic stroke and an image processed by RapidAI software from 11/1/2020 to 4/30/2021 at a regional hospital system. Only M1 LVOs were included. Sensitivities, specificities, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the following: Rapid LVO detection, gaze deviation (GD), hyperdense sign (HDS), Tmax >6 seconds, and NIHSS at presentation. The NNR was calculated for an M1 occlusion.Results:559 patients were included in this study. M1 occlusion was detected in 42 (7.5%) cases. Rapid LVO detection software was found to have a sensitivity of 71%, specificity of 94%, PPV of 49%, and NPV of 92% for a M1 occlusion. When both GD and HDS were combined with Rapid LVO, the specificity and PPV increased to 100% for a M1 occlusion. A negative LVO software combined with either a low (6s) or high (6s) Tmax threshold were found to have a specificity and PPV of 100% for no M1 occlusion. The combination of GD, HDS, Rapid LVO+ (for M1 occlusion) and Rapid LVO- with a low Tmax threshold (for no M1 occlusion) yielded 24 images NNR per 100 cases. When the combination of GD, HDS, Rapid LVO+ was combined with Rapid LVO- and a high Tmax threshold, the NNR per 100 cases was 16. With the addition of NIHSS6s threshold, the NNR is significantly decreased. As few as 9 images per 100 would be needed to be manually reviewed by a clinician during stroke triage.

Stroke, Volume 53, Issue Suppl_1, Page AWMP49-AWMP49, February 1, 2022. Background:D-dimer has been evaluated as an independent marker of ischemic stroke. The non-existence of a clear consensus and pooled data about the use of D-dimer as a predictive biomarker for assessing the risk of stroke recurrence led us to perform this systematic review and meta-analysis.Methods:Studies reporting the risk of stroke recurrence with varying degrees of high D-dimer levels were screened through August 2021 using PubMed/Medline, Scopus, EMBASE and Web of Science databases and relevant keywords. Random effects models by Dersimonian & Laird were used for meta-analysis and subgroup analysis. I2statistics were used for heterogeneity assessment. The leave-one-out method was used for sensitivity analysis.Results:This systematic review included 5040 patients from 9 studies consisting of >60% males. There was a high burden of cardiovascular comorbidities, smoking and diabetes in stroke patients with or without associated diagnoses and high D-dimer levels. Compared to low D-dimer levels, higher plasma D-dimer levels were associated with ~80% (aOR 1.79, 95% CI: 1.24-2.59) increased risk of stroke recurrence. The odds of stroke recurrence were significantly high in the stroke cohorts including patients with mean age

Stroke, Volume 53, Issue Suppl_1, Page AWMP97-AWMP97, February 1, 2022. Background and Purpose:Recent evidence suggests that patients with atrial fibrillation (AF) detected after stroke (AFDAS) may have a lower prevalence of cardiovascular comorbidities and lower risk of stroke recurrence than AF known before stroke (KAF). We performed a systematic search and meta-analysis to compare the characteristics of AFDAS and KAF.Methods:We searched PubMed, Scopus, and EMBASE for articles reporting differences between AFDAS and KAF until 30-June-2021. We performed random- or fixed-effects meta-analyses to evaluate differences between AFDAS and KAF in demographic factors, vascular risk factors, prevalent vascular comorbidities, structural heart disease, stroke severity, insular cortex involvement, stroke recurrence, and death.Results:We included 21 studies comprising 22,566 patients with ischemic stroke or transient ischemic attack. Patients with AFDAS had a lower CHA2DS2-VASc score (standardized mean difference [SMD] -0.47, 95% confidence interval [95% CI] -0.60, -0.34), and lower prevalence of vascular comorbidities including coronary artery disease (odds ratio [OR] 0.50, 95%CI 0.42, 0.61), congestive heart failure (OR 0.37, 95% CI 0.31, 0.44), peripheral artery disease (OR 0.44, 95%CI 0.29, 0.68), and previous stroke (RD 0.38, 95% CI 0.25, 0.58). Patients with AFDAS had a higher left ventricular ejection fraction (SMD 0.25, 95% CI 0.20, 0.30) and smaller mean atrial diameter (SMD -0.65, 95% CI -0.99, -0.31) than those with KAF. There were no differences in age, sex, stroke severity, or death rates between AFDAS and KAF. There were not enough studies to report differences in insular cortex involvement between AF types.Conclusions:We found significant differences in the prevalence of vascular comorbidities, structural heart disease, and stroke recurrence rates between AFDAS and KAF, suggesting that they constitute different clinical entities within the AF spectrum.

Stroke, Ahead of Print. Stroke disproportionately affects racial minorities, and the level to which stroke treatment practices differ across races is understudied. Here, we performed a systematic review of disparities in stroke treatment between racial minorities and White patients. A systematic literature search was performed on PubMed to identify studies published from January 1, 2010, to April 5, 2021 that investigated disparities in access to stroke treatment between racial minorities and White patients. A total of 30 studies were included in the systematic review. White patients were estimated to use emergency medical services at a greater rate (59.8%) than African American (55.6%), Asian (54.7%), and Hispanic patients (53.2%). A greater proportion of White patients (37.4%) were estimated to arrive within 3 hours from onset of stroke symptoms than African American (26.0%) and Hispanic (28.9%) patients. A greater proportion of White patients (2.8%) were estimated to receive tPA (tissue-type plasminogen activator) as compared with African American (2.3%), Hispanic (2.6%), and Asian (2.3%) patients. Rates of utilization of mechanical thrombectomy were also lower in minorities than in the White population. As shown in this review, racial disparities exist at key points along the continuum of stroke care from onset of stroke symptoms to treatment. Beyond patient level factors, these disparities may be attributed to other provider and system level factors within the health care ecosystem.

Stroke, Volume 53, Issue 2, Page 319-327, February 1, 2022. Background and Purpose:Recent evidence suggests that young women (18–45 years) may be at higher risk of ischemic strokes than men of the same age. The goal of this systematic review is to reconcile and synthesize existing evidence of sex differences among young adults with ischemic strokes.Methods:We searched PubMed from January 2008 to July 2021 for relevant articles and reviews and consulted their references. We included original studies that (1) were population based and (2) reported stroke incidence by sex or sex-specific incidence rate ratios of young adults ≤45 years. We excluded studies that (1) omitted measurements of error for incidence rates or incidence rate ratios, (2) omitted age adjustment, and (3) were not in English. Statistical synthesis was performed to estimate sex difference by age group (≤35, 35–45, and ≤45) and stroke type.Results:We found 19 studies that reported on sex-specific stroke incidence among young adults, including 3 that reported on overlapping data. Nine studies did not find a statistically significant sex difference among young adults ≤45 years. Three studies found higher rates of ischemic stroke among men among young adults ≥30 to 35 years. Four studies found more women with ischemic strokes among young adults ≤35 years. Overall, in young adults ≤35 years, the estimated effect size favored more ischemic strokes in women (incidence rate ratio, 1.44 [1.18–1.76],I2=82%) and a nonsignificant sex difference in young adults 35 to 45 years (incidence rate ratio, 1.08 [0.85–1.38],I2=95%).Conclusions:Overall, there were 44% more women ≤35 years with ischemic strokes than men. This gap narrows in young adults, 35 to 45 years, and there is conflicting evidence whether more men or women have ischemic strokes in the 35 to 45 age group.

Stroke, Volume 53, Issue 2, Page 328-337, February 1, 2022. Background and Purpose:Stroke is one of the leading causes of mortality, and women are impacted more from stroke than men in terms of their absolute number and in having worse outcomes. A growing number of studies have explored the association between pregnancy complications, pregnancy outcomes, and stroke. Limited studies, however, have investigated links involving infertility, miscarriage, and stillbirth, which could plausibly be associated via a background of endocrine conditions, endothelial dysfunction, and chronic systematic inflammation. This review aims to summarize current evidence and provide up-to-date information on the associations of infertility, miscarriage, and stillbirth, with stroke incidence.Methods:A comprehensive literature search was conducted for cohort and case-control studies on associations between infertility, miscarriage, stillbirth, and stroke up to September 26, 2020. Seven databases were searched: PubMed, Embase, Cochrane, CINIHL, PsyclNFO, Wanfang, and CNKI. Random-effects models were used to estimate the pooled hazard ratios (HRs) and 95% CIs.Results:Sixteen cohort studies and 2 case-control studies enrolling 7 808 521 women were included in this meta-analysis. Women who had experienced miscarriage or stillbirth were at higher risk of stroke (miscarriage: HR, 1.07 [95% CI, 1.00–1.14]; stillbirth: HR, 1.38 [95% CI, 1.11–1.71]) than other women. The HRs of stroke for each additional miscarriage and stillbirth were 1.13 (95% CI, 0.96–1.33) and 1.25 (95% CI, 1.06–1.49), respectively. In subgroup analysis, increased risk of stroke was associated with repeated miscarriages and stillbirths (miscarriage ≥3: HR, 1.42 [95% CI, 1.05–1.90]; stillbirth ≥2: HR, 1.14 [95% CI, 1.04–1.26]). Associations between infertility and stroke were inconsistent and inconclusive (HR, 1.07 [95% CI, 0.87–1.32]).Conclusions:Miscarriage and stillbirth are associated with increased risk of stroke among women, which could be used as a contributing risk factor to help identify women at higher risk of stroke.

Stroke, Volume 53, Issue 2, Page 345-354, February 1, 2022. Background and Purpose:Women have worse outcomes than men after stroke. Differences in presentation may lead to misdiagnosis and, in part, explain these disparities. We investigated whether there are sex differences in clinical presentation of acute stroke or transient ischemic attack.Methods:We conducted a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Inclusion criteria were (1) cohort, cross-sectional, case-control, or randomized controlled trial design; (2) admission for (suspicion of) ischemic or hemorrhagic stroke or transient ischemic attack; and (3) comparisons possible between sexes in ≥1 nonfocal or focal acute stroke symptom(s). A random-effects model was used for our analyses. We performed sensitivity and subanalyses to help explain heterogeneity and used the Newcastle-Ottawa Scale to assess bias.Results:We included 60 studies (n=582 844; 50% women). In women, headache (pooled odds ratio [OR], 1.24 [95% CI, 1.11–1.39]; I2=75.2%; 30 studies) occurred more frequently than in men with any type of stroke, as well as changes in consciousness/mental status (OR, 1.38 [95% CI, 1.19–1.61]; I2=95.0%; 17 studies) and coma/stupor (OR, 1.39 [95% CI, 1.25–1.55]; I2=27.0%; 13 studies). Aspecific or other neurological symptoms (nonrotatory dizziness and non-neurological symptoms) occurred less frequently in women (OR, 0.96 [95% CI, 0.94–0.97]; I2=0.1%; 5 studies). Overall, the presence of focal symptoms was not associated with sex (pooled OR, 1.03) although dysarthria (OR, 1.14 [95% CI, 1.04–1.24]; I2=48.6%; 11 studies) and vertigo (OR, 1.23 [95% CI, 1.13–1.34]; I2=44.0%; 8 studies) occurred more frequently, whereas symptoms of paresis/hemiparesis (OR, 0.73 [95% CI, 0.54–0.97]; I2=72.6%; 7 studies) and focal visual disturbances (OR, 0.83 [95% CI, 0.70–0.99]; I2=62.8%; 16 studies) occurred less frequently in women compared with men with any type of stroke. Most studies contained possible sources of bias.Conclusions:There may be substantive differences in nonfocal and focal stroke symptoms between men and women presenting with acute stroke or transient ischemic attack, but sufficiently high-quality studies are lacking. More studies are needed to address this because sex differences in presentation may lead to misdiagnosis and undertreatment.

Stroke, Ahead of Print. Depression and anxiety each affect around 1 in 3 people during the first year after a stroke. Suicide causes the death of about 3 to 4/1000 stroke survivors during the first 5 years. This narrative review describes the best available evidence for the epidemiology of depression, anxiety, and suicide; their prevention; and the treatment of anxiety and depression. We conclude with directions for future research.

Stroke, Ahead of Print. Background and Purpose:Optimizing speech and language therapy (SLT) regimens for maximal aphasia recovery is a clinical research priority. We examined associations between SLT intensity (hours/week), dosage (total hours), frequency (days/week), duration (weeks), delivery (face to face, computer supported, individual tailoring, and home practice), content, and language outcomes for people with aphasia.Methods:Databases including MEDLINE and Embase were searched (inception to September 2015). Published, unpublished, and emerging trials including SLT and ≥10 individual participant data on aphasia, language outcomes, and time post-onset were selected. Patient-level data on stroke, language, SLT, and trial risk of bias were independently extracted. Outcome measurement scores were standardized. A statistical inferencing, one-stage, random effects, network meta-analysis approach filtered individual participant data into an optimal model examining SLT regimen for overall language, auditory comprehension, naming, and functional communication pre-post intervention gains, adjusting for a priori–defined covariates (age, sex, time poststroke, and baseline aphasia severity), reporting estimates of mean change scores (95% CI).Results:Data from 959 individual participant data (25 trials) were included. Greatest gains in overall language and comprehension were associated with >20 to 50 hours SLT dosage (18.37 [10.58–26.16] Western Aphasia Battery–Aphasia Quotient; 5.23 [1.51–8.95] Aachen Aphasia Test–Token Test). Greatest clinical overall language, functional communication, and comprehension gains were associated with 2 to 4 and 9+ SLT hours/week. Greatest clinical gains were associated with frequent SLT for overall language, functional communication (3–5+ days/week), and comprehension (4–5 days/week). Evidence of comprehension gains was absent for SLT ≤20 hours,
