Abstract
BACKGROUND Covert atrial fibrillation (AF) is a major cause of cryptogenic stroke. This study investigated whether a dose-dependent relationship exists between the frequency of premature atrial contractions (PACs) and AF detection in patients with cryptogenic stroke using an insertable cardiac monitor (ICM). METHODS We enrolled consecutive patients with cryptogenic stroke who underwent ICM implantation between October 2016 and September 2020 at 8 stroke centers in Japan. Patients were divided into 3 groups according to the PAC count on 24-hour Holter ECG: ≤200 (group L), >200 to ≤500 (group M), and >500 (group H). We defined a high AF burden as above the median of the cumulative duration of AF episodes during the entire monitoring period. We evaluated the association of the frequency of PACs with AF detection using log-rank trend test and Cox proportional hazard model and with high AF burden using logistic regression model, adjusting for age, sex, CHADS2 score. RESULTS Of 417 patients, we analyzed 381 patients with Holter ECG and ICM data. The median age was 70 (interquartile range, 59.5-76.5), 246 patients (65%) were males, and the median duration of ICM recording was 605 days (interquartile range, 397-827 days). The rate of new AF detected by ICM was higher in groups with more frequent PAC (15.5%/y in group L [n=277] versus 44.0%/y in group M [n=42] versus 71.4%/y in group H [n=62]; log-rank trend P<0.01). Compared with group L, the adjusted hazard ratios for AF detection in groups M and H were 2.11 (95% CI, 1.24-3.58) and 3.23 (95% CI, 2.07-5.04), respectively, and the adjusted odds ratio for high AF burden in groups M and H were 2.57 (95% CI, 1.14-5.74) and 4.25 (2.14-8.47), respectively. CONCLUSIONS The frequency of PACs was dose-dependently associated with AF detection in patients with cryptogenic stroke.

Abstract
Although low-dose direct oral anticoagulants (DOACs) are recommended for patients at high risk of bleeding complications, it remains unclear whether the dose reduction in real-world setting is also appropriate in patients after large-vessel occlusion (LVO) stroke. This study hypothesized that patients with atrial fibrillation (AF) and LVO receiving low-dose DOACs have an increased risk of ischemic and hemorrhagic events. The study aimed to assess 1 year morbidity and mortality in patients treated with standard-dose and low-dose apixaban after LVO stroke. A post hoc analysis was performed using the acute LVO registry data, which enrolled patients with AF and LVO who received apixaban within 14 days of stroke onset. The incidences of ischemic events (ischemic stroke, acute coronary syndrome, acute myocardial infarction, and systemic embolism), major bleeding events, and death from any cause were compared between patients receiving standard- and low-dose apixaban. Of 643 patients diagnosed with LVO, 307 (47.7%) received low-dose apixaban. After adjustment for clinically relevant variables, no significant differences were observed in the incidence of ischemic events (adjusted hazard ratio [aHR]: 2.12, 95% confidence interval [CI] 0.75-6.02), major bleeding events (aHR: 1.17, 95% CI 0.50-2.73), and death from any cause (aHR: 1.95, 95% CI 0.78-4.89) between patients receiving standard- and low-dose apixaban. No significant differences were observed in the incidence of ischemic events, major bleeding events, or death from any cause between patients with AF and LVO receiving standard- and low-dose apixaban.

Abstract
BACKGROUND Patients with acute ischemic stroke and active cancer have more severe neurological symptoms, elevated risks of stroke recurrence, and death compared with the general population. We examined whether von Willebrand factor (vWF) antigen levels at stroke onset were associated with the poor outcomes of patients with stroke and cancer. METHODS AND RESULTS Using data from 90 patients with acute ischemic stroke and active cancer who were registered in the SCAN (Ischemic Stroke in Patients With Cancer and Neoplasia) study, a prospective multicenter, observational study in Japan, we divided patients into 2 groups according to their median vWF antigen levels (high, n=46; or low, n=44). The high-vWF group had a significantly higher initial National Institutes of Health Stroke Scale score (median, 7 [interquartile range, 3-11.25] versus 3 [interquartile range, 1-8.5]; P<0.05) and a significantly higher incidence of cryptogenic stroke (32 [70%] versus 16 [36%]; P<0.01) and venous thromboembolism (7 [15%] versus 0 [0%]; P<0.01), as well as multiple lesions (28 [62%] versus 12 [27%]; P<0.001), than the low-vWF group. We observed no significant difference in the rate of stroke recurrence within 1 year between the groups. However, increased vWF levels were an independent predictor of death within 1 year of stroke onset, after adjusting for potential confounders (odds ratio, 6.77 [95% CI, 1.49-30.78]; P<0.05). CONCLUSIONS Elevated vWF antigen levels were associated with adverse outcomes in patients with cancer-associated stroke and may represent a useful biomarker to guide future therapeutic interventions.

Abstract
BACKGROUND Atrial fibrillation (AF) is known to be a strong risk factor for stroke. However, the risk of stroke recurrence in patients with cryptogenic stroke with AF detected after stroke by an insertable cardiac monitor (ICM) is not well known. We sought to evaluate the risk of ischemic stroke recurrence in patients with cryptogenic stroke with and without ICM-detected AF. METHODS AND RESULTS We retrospectively reviewed patients with cryptogenic stroke who underwent ICM implantation at 8 stroke centers in Japan. Cox regression models were developed using landmark analysis and time-dependent analysis. We set the target sample size at 300 patients based on our estimate of the annualized incidence of ischemic stroke recurrence to be 3% in patients without AF detection and 9% in patients with AF detection. Of the 370 patients, 121 were found to have AF, and 110 received anticoagulation therapy after AF detection. The incidence of ischemic stroke recurrence was 4.0% in 249 patients without AF detection and 5.8% in 121 patients with AF detection (P=0.45). In a landmark analysis, the risk of ischemic stroke recurrence was not higher in patients with AF detected ≤90 days than in those without (hazard ratio, 1.47 [95% CI, 0.41-5.28]). In a time-dependent analysis, the risk of ischemic stroke recurrence did not increase after AF detection (hazard ratio, 1.77 [95% CI, 0.70-4.47]). CONCLUSIONS The risk of ischemic stroke recurrence in patients with cryptogenic stroke with ICM-detected AF, 90% of whom were subsequently anticoagulated, was not higher than in those without ICM-detected AF.

Abstract
BACKGROUND The effect of nutritional status on survival in ischemic stroke patients with active cancer remains unclear. METHODS This study retrospectively evaluated ischemic stroke patients with active cancer admitted to a university hospital in Japan between 2006 and 2016. Patients were followed for 2 years after stroke. The controlling nutritional status (CONUT) score was used to classify undernutrition degree into 4 groups: normal, light, moderate, and severe. Survival rates were compared using the Kaplan-Meier method. Hazard ratio (HR) and 95 % confidence intervals (CIs) for mortality were calculated using Cox regression models. RESULTS A total of 158 patients (31 % women; median age: 71 years) were analyzed. Of these, 47 % had distant metastasis. The median (interquartile range) National Institute of Health Stroke Scale and CONUT scores were 4 (1-10) and 5 (3-7), respectively. Kaplan-Meier curve indicated that patients with poorer nutritional status had worse outcomes (overall log-rank test, p < 0.001). The univariable Cox regression analysis showed that the HR (95 % CI) for the light, moderate, and severe groups were 1.14 (0.45-2.86), 3.01 (1.27-7.12), and 2.94 (1.10-7.84), respectively. This statistical significance did not persist after adjustment for potential confounders (HR [95 % CI] for the light, moderate, and severe groups were 0.95 [0.36-2.49], 1.56 [0.57-4.28], and 1.34 [0.37-4.92], respectively). Past stroke, distant metastasis, and plasma D-dimer levels on admission were independent predictors of prognosis. CONCLUSIONS This single-center, retrospective study suggests that nutritional status serves as a prognostic indicator for ischemic stroke patients with active cancer. However, the effect is not statistically independent.

Abstract
BACKGROUND An insertable cardiac monitor (ICM) and transesophageal echocardiography (TEE) are useful for investigating potential embolic sources in cryptogenic stroke, of which atrial fibrillation (AF) is a critical risk factor for stroke recurrence. The association of left atrial appendage flow velocity (LAA-FV) on TEE with ICM-detected AF is yet to be elucidated. METHODS CRYPTON-ICM (CRYPTOgenic stroke evaluation in Nippon using ICM) is a multicenter registry of cryptogenic stroke with ICM implantation, and patients whose LAA-FV was evaluated on TEE were enrolled. The primary outcome was the detection of AF (> 2 min) on ICM. Receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off of LAA-FV, and factors associated with ICM-detected AF were assessed. RESULTS A total of 307 patients (age 66.6 ± 12.3 years; 199 males) with median follow-up of 440 (interquartile range 169-726) days were enrolled; AF was detected in 101 patients. The lower-tertile LAA-FV group had older age, more history of congestive heart failure, and higher levels of B-type natriuretic peptide (BNP) or N-terminal proBNP (all P < 0.05). On ROC analysis, LAA-FV < 37.5 cm/s predicted ICM-detected AF with sensitivity of 26.7% and specificity of 92.2%. After adjustment for covariates, the lower tertile of LAA-FV (hazard ratio [HR], 1.753 [1.017-3.021], P = 0.043) and LAA-FV < 37.5 cm/s (HR 1.987 [1.240-3.184], P = 0.004) predicted ICM-detected AF. CONCLUSIONS LAA-FV < 37.5 cm/s predicts AF. TEE is useful not only to evaluate potential embolic sources, but also for long-term detection of AF on ICM by measuring LAA-FV in cryptogenic stroke. http://www.umin.ac.jp/ctr/ (UMIN000044366).

Abstract
We report a case of an 80-year-old woman with botulism from 2020 in Osaka, Japan. The patient complained of dysarthria and dizziness. On the same day, the patient developed respiratory failure, and was intubated and placed on mechanical ventilation. Subsequently, ophthalmoparesis and quadriparesis progressed rapidly. Ten days after onset, the patient failed to respond to any external stimulation. Blood tests showed anemia, and computed tomography revealed undiagnosed cervical cancer. Initially, diagnosis of neuromuscular junction disorder and acute motor neuropathy, including paraneoplastic syndrome, were considered. However, intravenous immunoglobulin therapy and plasma exchange were ineffective. A fecal sample on day 30 showed a large number of C. botulinum spores. On day 34, a mouse bioassay revealed botulinum toxin type A in the patient's serum; therefore, a botulinum antitoxin was administered. Later, the patient's muscle strength was gradually improved. However, severe muscle paralysis persisted, and the patient died of cachexia owing to cervical cancer on day 196. The etiology of this case was unknown because no contaminated food was identified during an inspection of the patient's home. Fecal 16S rRNA gene sequencing revealed dysbiosis of the intestinal microbiota with abundant Enterococcus species. Long-lasting excretion of substantial botulinum spores even on day 30 indicated colonization of C. botulinum in the intestinal tract. This case suggests that C. botulinum colonization with co-existing intestinal dysbiosis may be associated with severe and prolonged symptoms of botulism.

Abstract
Aims Current guidelines recommend measuring carotid intima-media thickness (IMT) at the far wall of the common carotid artery (CCA). We aimed to precisely quantify associations of near vs. far wall CCA-IMT with the risk for atherosclerotic cardiovascular disease (CVD, defined as coronary heart disease or stroke) and their added predictive values. Methods and results We analysed individual records of 41 941 participants from 16 prospective studies in the Proof-ATHERO consortium {mean age 61 years [standard deviation (SD) = 11]; 53% female; 16% prior CVD}. Mean baseline values of near and far wall CCA-IMT were 0.83 (SD = 0.28) and 0.82 (SD = 0.27) mm, differed by a mean of 0.02 mm (95% limits of agreement: -0.40 to 0.43), and were moderately correlated [r = 0.44; 95% confidence interval (CI): 0.39-0.49). Over a median follow-up of 9.3 years, we recorded 10 423 CVD events. We pooled study-specific hazard ratios for CVD using random-effects meta-analysis. Near and far wall CCA-IMT values were approximately linearly associated with CVD risk. The respective hazard ratios per SD higher value were 1.18 (95% CI: 1.14-1.22; I² = 30.7%) and 1.20 (1.18-1.23; I² = 5.3%) when adjusted for age, sex, and prior CVD and 1.09 (1.07-1.12; I² = 8.4%) and 1.14 (1.12-1.16; I²=1.3%) upon multivariable adjustment (all P < 0.001). Assessing CCA-IMT at both walls provided a greater C-index improvement than assessing CCA-IMT at one wall only [+0.0046 vs. +0.0023 for near (P < 0.001), +0.0037 for far wall (P = 0.006)]. Conclusions The associations of near and far wall CCA-IMT with incident CVD were positive, approximately linear, and similarly strong. Improvement in risk discrimination was highest when CCA-IMT was measured at both walls.

Abstract
Background Limited data exist on the prognostic factors for patients with ischemic stroke and active cancer. Methods and Results We conducted a prospective, multicenter, observational study in Japan, including patients with acute ischemic stroke and active cancer, to investigate the prognostic factors. We followed up the patients for 1 year after stroke onset. The patients were divided into 2 groups according to cryptogenic stroke and known causes (small-vessel occlusion, large-artery atherosclerosis, cardioembolism, and other determined cause), and survival was compared. The hazard ratios (HRs) and 95% CIs for mortality were calculated using Cox regression models. We identified 135 eligible patients (39% women; median age, 75 years). Of these patients, 51% had distant metastasis. A total of 65 (48%) and 70 (52%) patients had cryptogenic stroke and known causes, respectively. Patients with cryptogenic stroke had significantly shorter survival than those with known causes (HR [95% CI], 3.11 [1.82-5.32]). The multivariable Cox regression analysis revealed that distant metastasis, plasma D-dimer levels, venous thromboembolism (either deep venous thrombosis or pulmonary embolism) complications at stroke onset were independent predictors of mortality after adjusting for potential confounders. Cryptogenic stroke was associated with prognosis in univariable analysis but was not significant in multivariable analysis. The plasma D-dimer levels stratified the prognosis of patients with ischemic stroke and active cancer. Conclusions The prognosis of patients with acute ischemic stroke and active cancer varied considerably depending on stroke mechanism, distant metastasis, and coagulation abnormalities. The present study confirmed that coagulation abnormalities were crucial in determining the prognosis of such patients.

Abstract
Blood-brain barrier (BBB) disruption contributes to brain injury and neurological impairment. Tight junctions (TJs) and cell-cell adhesion complexes develop between endothelial cells in the brain to establish and maintain the BBB. Occludin, the first transmembrane protein identified in TJs, has received intense research interest because numerous in vitro studies have suggested its importance in maintaining BBB integrity. However, its role in maintaining BBB integrity after ischemic stroke is less clear owing to the lack of in vivo evidence. This study aimed to investigate the dynamics and function of occludin across the acute and chronic phases after stroke using occludin-deficient mice. By photochemically induced thrombosis model, the expression of occludin was decreased in brain endothelial cells from ischemic lesions. The neurological function of occludin-deficient mice was continuously impaired compared to that of wild-type mice. BBB integrity evaluated by Evans blue and 0.5-kDa fluorescein in the acute phase and by 10-kDa fluorescein isothiocyanate-labeled dextran in the chronic phase was decreased to a greater extent after stroke in occludin-deficient mice. Furthermore, occludin-deficient mice showed decreased claudin-5 and neovascularization after stroke. Our study reveals that occludin plays an important role from the acute to the chronic phase after ischemic stroke in vivo.

Abstract
BACKGROUND AND OBJECTIVES Intracranial artery stenosis is the predominant etiology of ischemic stroke in the Asian population. Furthermore, the presence of the RNF213 p.R4810K variant, which is a susceptibility gene for moyamoya disease, increases the risk of ischemic stroke attributable to large-artery atherosclerosis. Accordingly, we hypothesized that this genetic variant may affect the long-term outcome of intracranial artery stenosis in the East Asian population. We thus aimed to examine the effect of this variant on the long-term progression and prognosis of intracranial artery stenosis. METHODS Using a prospective database, we identified adult patients with intracranial artery stenosis who underwent periodic MRI examinations for >5 years. We evaluated stenosis progression using a validated visual grading system. We excluded patients diagnosed with moyamoya disease at the time of initial MRI. Genotyping of RNF213 p.R4810K was performed at the end of the follow-up period. RESULTS Among 52 eligible patients, 22 (42%) were carriers of the RNF213 p.R4810K variant. The median follow-up duration was 10.3 years. During the follow-up period, progression of intracranial artery stenosis was observed in 64% variant carriers and 27% noncarriers. There was a significant association of the variant with time to progression of intracranial artery stenosis (hazard ratio [HR] 3.31, 95% CI 1.38-7.90, p = 0.007), and time to the composite endpoint of symptomatic stroke and transient ischemic attack (HR 3.70, 95% CI 1.15-11.86, p = 0.028), but not to symptomatic stroke alone (HR 2.18, 95% CI 0.62-7.74, p = 0.23). Two variant carriers with progression were newly diagnosed with moyamoya disease. DISCUSSION Our findings indicated that the RNF213 p.R4810K variant increases the risk of intracranial artery stenosis progression.

Abstract
A 53-year-old woman with severe coronavirus disease 2019 (COVID-19) pneumonia was admitted and treated with intravenous unfractionated heparin for thromboprophylaxis under general anesthesia with mechanical ventilation. She developed right hemiparesis after hospitalization due to a large hemorrhagic infarction. Her platelet count decreased from 243,000/μL at administration to 121,000/μL. Anti-platelet factor 4-heparin antibody testing was positive according to a latex immunoturbidimetric assay. She was therefore diagnosed with heparin-induced thrombocytopenia. We immediately stopped the heparin and started argatroban; the platelet count recovered, and thrombosis did not relapse. Physicians should consider heparin-induced thrombocytopenia as a cause of ischemic stroke in patients with COVID-19 infection.

Abstract
Background The major risk factors for atherosclerotic cardiovascular disease differ by race or ethnicity but have largely been defined using populations of European ancestry. Despite the rising prevalence of cardiovascular disease in Africa there are few related data from African populations. Therefore, we compared the association of established cardiovascular risk factors with carotid-intima media thickness (CIMT), a subclinical marker of atherosclerosis, between African, African American, Asian, European, and Hispanic populations. Methods and Results Cross-sectional analyses of 34 025 men and women drawn from 15 cohorts in Africa, Asia, Europe, and North America were undertaken. Classical cardiovascular risk factors were assessed and CIMT measured using B-mode ultrasound. Ethnic differences in the association of established cardiovascular risk factors with CIMT were determined using a 2-stage individual participant data meta-analysis with beta coefficients expressed as a percentage using the White population as the reference group. CIMT adjusted for risk factors was the greatest among African American populations followed by Asian, European, and Hispanic populations with African populations having the lowest mean CIMT. In all racial or ethnic groups, men had higher CIMT levels compared with women. Age, sex, body mass index, and systolic blood pressure had a significant positive association with CIMT in all races and ethnicities at varying magnitudes. When compared with European populations, the association of age, sex, and systolic blood pressure with CIMT was weaker in all races and ethnicities. Smoking (beta coefficient, 0.39; 95% CI, 0.09-0.70), body mass index (beta coefficient, 0.05; 95% CI, 0.01-0.08) and glucose (beta coefficient, 0.13; 95% CI, 0.06-0.19) had the strongest positive association with CIMT in the Asian population when compared with all other racial and ethnic groups. High-density lipoprotein-cholesterol had significant protective effects in African American (beta coefficient, -0.31; 95% CI, -0.42 to -0.21) and African (beta coefficient, -0.26; 95% CI, -0.31 to -0.19) populations only. Conclusions The strength of association between established cardiovascular risk factors and CIMT differed across the racial or ethnic groups and may be due to lifestyle risk factors and genetics. These differences have implications for race- ethnicity-specific primary prevention strategies and also give insights into the differential contribution of risk factors to the pathogenesis of cardiovascular disease. The greatest burden of subclinical atherosclerosis in African American individuals warrants further investigations.

Abstract
Objective The underlying pathophysiology varies according to stroke subtype. However, stroke heterogeneity among patients with systemic lupus erythematosus (SLE) remains unstudied. We hypothesized that the contribution of SLE to stroke might vary according to its subtype and investigated the associations of SLE and various stroke subtypes. Methods Diagnostic codes and electronic medical records were used to identify 70 patients with SLE who developed acute cerebral infarction or intracerebral hemorrhaging at four tertiary referral hospitals between 2008 and 2018. Intracerebral hemorrhaging was classified as lobar or deep, while cerebral infarction was classified according to the SSS-TOAST criteria. Physician notes were used to identify SLE activity, and their prevalences were compared among stroke subtypes. Outcomes were collected from the patients' medical records. Results The most common stroke subtype in patients with SLE was that of undetermined causes (31%), followed by small artery occlusion (16%), cardioaortic embolism (13%), other causes (11%), lobar hemorrhaging (10%), deep hemorrhaging (10%), and large artery atherosclerosis (9%). Stroke onset occurred during a period of high SLE activity in 21 patients (30%). The proportion of patients with high SLE activity varied according to stroke subtype (p=0.039) and was highest for cerebral infarction with undetermined causes. Stroke recurrence or death was observed in 40% of patients within 5 years after the initial stroke onset. Conclusion The contributions of SLE to stroke varied significantly according to the stroke subtype. Given the unfavorable prognosis, close stroke subtype-specific observation by rheumatologists and stroke specialists is recommended after stroke events.

Abstract
AIM The ring finger protein 213 gene (RNF213) p.R4810K variant is a major susceptibility gene for intracranial arterial stenosis in East Asia. We hypothesized that if intracranial arterial stenosis is induced by a non-atherosclerotic mechanism similar to moyamoya disease, the patients with RNF213 p.R4810K variant may have a lower cumulative atherosclerotic burden than the non-carriers. METHODS A total of 112 participants with intracranial arterial stenosis were enrolled in this multicenter cross-sectional study. We compared the prevalence of atherosclerotic risk factors and three different cardiovascular risk scores (Essen Stroke Risk Score, Framingham Risk Score, and Suita Risk Score) between the RNF213 p.R4810K variant carriers and non-carriers. Patients with moyamoya disease were excluded from the study. RESULTS The RNF213 p.R4810K variant carriers were younger than the non-carriers (P<0.001). The prevalence of each atherosclerotic risk factor was not significant, but it tended to be lower in the variant carriers. The Essen Stroke Risk Score (carriers: 2.3±1.5 vs. non-carriers: 2.9±1.5, P=0.047), Framingham Risk Score (10.7±6.4 vs. 15.3±6.2, P=0.001), and Suita Risk Score (35.4±15.8 vs. 48.7±15.2, P<0.001) were significantly lower in the variant carriers. Among the three risk scores, the Suita score showed the highest predictive accuracy for the variant carriers. CONCLUSIONS RNF213 p.R4810K variant carriers have a lower cumulative atherosclerotic burden than non-carriers among patients with intracranial arterial stenosis. New therapeutic approaches beyond the standard management of atherosclerotic risk factors are required to prevent the development of intracranial arterial stenosis.

Abstract
Abstract
Background and objective
Living alone is reported as an independent risk factor for worse clinical outcomes after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Manifestations of psychological stress such as depression and anxiety in patients living alone is thought to be associated with subsequent cardiovascular events. The impact of living alone on the psychological factors of patients may be differ depending on their living environment. However, comparison of the effects of living alone in different living environment on the prognosis of patients with ACS has not been reported.
Purpose
The aim of the present study was to compare the clinical effect of living alone on clinical outcomes in patients with ACS between urban area and rural area.
Methods
Data from a multi-center, observational study of consecutive patients who underwent emergency PCI for ACS between January 2012 and December 2016 were analyzed. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE). MACCE was defined as composite of cardiovascular death, ACS, and stroke.
Results
In this study, 1349 patients were enrolled and divided into two population according to their living environment: urban area population (n=417), and rural area population (n=932). In urban area population, 87 patients (20.9%) were living alone, and 330 (79.1%) were living together. In rural area population, 169 (18.1%) were living alone, and 763 (81.9%) were living together. There are no significant differences in baseline characteristics between the living alone group and the living together group in both urban area population and rural area population. During a median follow-up period of 2.1 years, Kaplan-Meier curves showed the living alone group had higher risk of MACCE than the living together group in urban area population (log-rank, p=0.01). On the other hands, there are no significant differences in the incidences of MACCE between two groups in rural area population (p=0.86). After adjustment for other covariates, the living alone was significantly associated with MACCE (hazard ratio [HR], 2.83; 95% confidential interval [CI], 1.16–6.91; p=0.02) compared with the living together group in urban area population. However, in rural area population, the living alone group was not significantly associated with MACCE (HR, 1.02; 95% CI, 0.66–1.57; p=0.92) compared with the living together group.
Conclusion
Living alone was significantly associated with worse clinical outcomes after emergency PCI of ACS in urban area but not in rural area.

Abstract
Abstract
Background and objective
Percutaneous coronary intervention (PCI) with metallic coronary stent (bare-metal stents [BMS] and drug-eluting stents [DES]) implantation is most frequently performed therapeutic procedures for coronary artery disease. In-stent restenosis (ISR) is a critical drawback of metallic coronary stents. Incidence of ISR has been reported in up to 30% after BMS implantation. The use of DES has greatly reduced the proportion of restenosis compared with the BMS. However, ISR still remains the primary concern after PCI even in the contemporary DES era, and thought to be associated with worse clinical outcomes. However, comparative data on ISR and de novo lesions are rare.
Purpose
The aim of the present study was to compare the clinical outcomes after PCI for the de novo lesion and the ISR lesion.
Methods
We performed a retrospective analysis of patients who underwent PCI between 2013 and 2020. The incidences of major adverse cardiac and cerebrovascular events (MACCE) and all-cause death were evaluated. MACCE was defined as composite of cardiovascular death, non-fatal myocardial infarction, and stroke.
Results
In this study, 1538 patients were enrolled and divided into two groups: PCI for de novo lesion group (n=1258, 81.8%), and PCI for ISR lesion group (n=280, 18.2%). Patients in the ISR lesion group were significantly older and had higher prevalence of hypertension, diabetes mellitus, dyslipidemia and chronic kidney disease than patients in the de novo lesion group. During a median follow-up period of 1.9 years, Kaplan-Meier curves showed no significant differences in the incidences of MACCE (log-rank, p=0.86) and all-cause death (p=0.84) between two groups. After adjustment for other covariates, PCI for ISR lesion were not significantly associated with MACCE (hazard ratio [HR], 1.10; 95% confidential interval [CI], 0.61–1.97; p=0.76) and all-cause death (HR, 0.93; 95% CI, 0.56–1.56; p=0.79)
Conclusion
PCI for the ISR lesion was not associated with worse clinical outcomes compared with PCI for the de novo lesion.

Abstract
Abstract
Background
Fractional Flow Reserve (FFR) derived from coronary computed tomography angiography (CCTA) enables anatomical and hemodynamical assessment of coronary artery disease. CT-FFR, which can be acquired on-site workstation using fluid structure interaction during the multiple optimal diastolic phase, has an incremental diagnostic value over conventional CCTA. However, few studies are focused on investigating the appropriate measurement location of CT-FFR, considering the prognosis, using CCTA as a standalone modality.
Purpose
The aim of this study is to assess the clinical impact on CT-FFR with an appropriate measurement.
Methods
A total of 370 consecutive patients who underwent CCTA in a single-heartbeat scan with a phase window of 70% to 99% of the R-R interval, showing 50–90% stenosis of at least one major epicardial vessel measuring ≥1.8 mm in diameter on CCTA were retrospectively analyzed and followed during a median follow up 2.9 years. CT-FFR values were measured at three points: 1, 2 cm distal to a target lesion (CT-FFR1cm, 2cm) and the vessel terminus (CT-FFRlowest), and a CT-FFR value ≤0.80 was considered abnormal. The endpoint was MACE, a composite of cardiac death, non-fatal MI, and unplanned revascularization.
Results
The incidence of MACE occurred in 8.4% (31/370) of the whole patients, including four cardiac deaths, ten all cause deaths, two non-fatal MI, and twenty unplanned revascularization. The Kaplan-Meier survival analysis demonstrated a significantly higher cumulative MACE rate in patients with positive CT-FFR1cm and 2cm than those with negative CT-FFR1cm and 2cm, while there was no significant difference between negative and positive in CT-FFRlowest, among patients with negative CT-FFR1cm and 2cm (Figure 1). Among 221 patients, who did not perform early revascularization within 90 days from CCTA, there was no significant difference in CT-FFRlowest in the incidence of MACE. In contrast, the risk of MACE was significantly higher in both positive CT-FFR1cm and CT-FFR2cm (Figure 2).
Conclusion
From a view point of clinical outcome for patients with moderate to severe stenosis on CCTA, a CT-FFR value when measured at 1-to-2 cm distal to a target lesion could be feasible for the deferral of unnecessary invasive coronary angiography safely. Moreover, CT-FFR1–2cm showed better risk stratification measurement rather than CT-FFRlowest, based on future adverse cardiac event.

Near-infrared spectroscopy (NIRS) and intravascular ultrasound (IVUS) are useful imaging modalities to identify lipid-rich plaque (LRP) which is associated with an increased risk of future cardiovascular events in individuals undergoing PCI. Pathological studies have raised concerns that treating LRP with stents may impair vascular healing. However, the impact of stent implantation to LRP lesions was less known. Moreover, little information is available about changes in the extent of LRP at before and after PCI.
Purpose
The aim of this study was to investigate changes in LRP by NIRS between pre- and post-stent implantation, and to evaluate an association among impact of LRP by NIRS at pre- and post-stenting and late lumen loss (LLL) by angiography.
Methods
We studied 175 lesions in 149 patients who underwent PCI under NIRS-IVUS guidance and follow-up angiography at 8-month later from 2017 to 2020. Plaque characteristics on IVUS, the extent of LRP [defined as a long segment with a 4-mm maximum lipid core burden index (maxLCBI4mm)] on NIRS, and quantitative coronary angiography measurements were analyzed. We evaluated a change of the extent of LRP between pre- and post-stenting at index PCI procedure, and association between the extent of LRP and a 8-month LLL at follow-up coronary angiography. A large LRP was defined as maxLCBI4mm>400 at pre-stenting.
Results
Mean age was 64.5 years old, and 123 (82%) patients were male. The prevalence of large LRP was 51% and median plaque burden at minimum lumen area was 81%. The extent of LRP at culprit lesion significantly decreased from pre- to post-stenting (median maxLCBI4mm [interquartile range (IQR)]: 407 [199, 580] to 133 [13, 319], p<0.001) (Figure 1). In multivariable liner regression analysis, independent predictors for the reduction of LRP were a pre-stenting LRP (β coefficient = −57.0, 95% confidence interval (CI) [−65.1 to −48.8], p<0.001) and plaque burden (β coefficient = −30.0, 95% CI [−56.6 to −3.4], p<0.001), respectively. On the other hands, patient comorbidities, lipid profile and inflammatory markers were not associated with the reduction of LRP (all p>0.05). Median LLL at follow-up angiogram was 0.17 [0.07–0.35] mm. Both the extent of pre- and post-stenting LRP were not associated with LLL (r=0.018, p=0.80 and r=0.022, p=0.76, respectively) (Figure 2). In addition, there was no significant difference in LLL between the post-stenting large and non-large LRP (median [IQR] 0.18 [0.08–0.35] vs. 0.17 [0.07–0.35]; P=0.95).
Conclusions
This study showed coronary stent implantation significantly reduced the NIRS-derived LRP in patients undergoing PCI. Although the extent of pre-stenting LRP and IVUS plaque burden predicted the reduction of LRP, the extent of pre- and post-stenting LRP were not associated with LLL. These findings suggest that stent implantation for LRP, even in a large LRP, is safe and does not affect LLL.

Abstract
Abstract
Background
Asians have a much lower incidence of adverse coronary events than Caucasians, and the characteristics of vulnerable plaque might be different among the ethnics.
Purpose
The aim of this study was to investigate the clinical characteristics of lipid-rich plaque (LRP) in the Asian population and we also aimed to distinguish the characteristics of an acute coronary syndrome (ACS) culprit lesion and a chronic coronary syndrome (CCS) culprit lesion. Furthermore, we evaluated the association between lipid core burden index (LCBI) and cardiovascular risk factors, lipid profiles, and inflammatory biomarkers, as determined in vivo by near infrared spectroscopy intravascular ultrasound (NIRS-IVUS) imaging in patients undergoing percutaneous coronary intervention (PCI).
Methods
We evaluated 207 patients (ACS, n=75; CCS, n=132) who underwent PCI under NIRS-IVUS. Plaque characteristics and the extent of LRP [defined as a long segment with a 4-mm maximum LCBI (maxLCBI4mm)] on NIRS in de-novo culprit and non-culprit segments were analyzed.
Results
The mean age was 65 years old and 82% of patients were male. The ACS culprit lesions had a significantly higher maxLCBI4mm (median [interquartile range (IQR)]: 533 [385–745] vs. 361 [174–527], p<0.001) than the CCS culprit lesions. Whereas, no significant difference was seen in maxLCBI4mm between ACS and CCS non-culprit lesion segments (246 [53, 342] vs. 185 [37, 350], p=0.47) (Figure 1). Receiver-operating characteristic analysis showed that the NIRS maxLCBI4mm could distinguish the ACS culprit segment from the CCS culprit segment, with a sensitivity of 73% and a specificity of 69% (c-statistic = 0.69; p<0.001, cut-off value of max LCBI4mm = 408) (Figure 2). On multivariate logistic analysis, a large LRP (defined as maxLCBI4mm ≥400) was the strongest independent predictor of the ACS culprit segment (odds ratio, 3.87; 95% confidence interval, 1.95–8.02). In non-culprit segments, 19.8% of patients had at least one large LRP without a small lumen. No significant correlation was found between the extent of LRP and circulating lipid profiles and inflammatory makers biomarkers (hs-CRP, IL-6, TNF-α) in both the culprit and non-culprit lesion segments, whereas the extent of LRP was positively correlated with IVUS plaque burden (r=0.24, p<0.001).
Conclusions
We confirmed that NIRS-IVUS plaque assessment could be useful to differentiate ACS from CCS culprit lesions, and that a threshold maxLCBI4mm ≥400 was clinically suitable in Japanese patients. No systemic surrogate markers were found to be associated with the extent of LRP by NIRS in culprit and non-culprit segments. Consequently, we believe that direct intravascular evaluation of coronary plaque characteristics remains important for identification of high-risk LRP.

Abstract
Introduction Dysregulation of the RING finger protein 213 (RNF213) gene impairs vascular formation in experimental animal models. In addition, vascular abnormalities in the circle of Willis are associated with cerebrovascular disease. Here, we evaluated the relationship between the East Asian founder variant RNF213 p.R4810K and consequent anatomical variations in the circle of Willis in cerebrovascular disease. Patients and Methods The present study is an observational cross-sectional study. It included patients with acute anterior circulation non-cardioembolic stroke admitted to our institution within 7 days of symptom onset or last-known-well from 2011 to 2019, and those who participated in the National Cerebral and Cardiovascular Center Biobank. We compared anatomical variations of the vessels constituting the circle of Willis between RNF213 p.R4810K (c.14429G > A) variant carriers and non-carriers using magnetic resonance angiography and assessed the association between the variants and the presence of the vessels constituting the circle of Willis. Patients with moyamoya disease were excluded. Results Four hundred eighty-one patients [146 women (30%); median age 70 years; median baseline National Institutes of Health Stroke Scale score 5] were analyzed. The RNF213 p.R4810K variant carriers (n = 25) were more likely to have both posterior communicating arteries (PComAs) than the variant non-carriers (n = 456) (56% vs. 13%, P < 0.01). Furthermore, variant carriers were less likely to have an anterior communicating artery (AComA) than non-carriers (68% vs. 84%, P = 0.04). In a multivariate logistic regression analysis, the association of RNF213 p.R4810K variant carriers with the presence of both PComAs and the absence of AComA remained significant. Conclusion Our findings suggest that the RNF213 p.R4810K variant is an important factor in determining anatomical variations in the circle of Willis.

Abstract
Background and Purpose: Once a stroke occurs in a patient with atrial fibrillation (AF), it is likely to be severe. Patients with newly diagnosed AF after stroke and those with known AF before stroke have different background characteristics, yet the difference in stroke severity has not been sufficiently evaluated. In the current study, we compared the stroke severity and in-hospital outcomes between these patient groups. Methods: We retrospectively analyzed a database of 196 patients with acute ischemic stroke and AF between January 2010 and October 2019. We divided the patients into two groups: patients with “newly diagnosed AF” and those with “known AF.” We assessed the stroke severity using the National Institutes of Health Stroke Scale (NIHSS) score on admission and in-hospital outcomes using the modified Rankin Scale (mRS) score at discharge. Results: The proportion of newly diagnosed AF was 33% (64/196). There were no differences in age, hypertension, diabetes mellitus, and past history of heart failure between patients with newly diagnosed AF and those with known AF. Patients with newly diagnosed AF were associated with a lower proportion of male sex (male; 50 vs. 67%, p < 0.05), a lower proportion of past history of stroke (12 vs. 35%, p < 0.01), a lower CHA2DS2-VASc score (median [interquartile range]; 3 [2–4] vs. 3.5 [3–5], p < 0.01), and a lower proportion of pre-stroke oral anticoagulation (5 vs. 59%, p < 0.01). There were no differences in the NIHSS score on admission (12 [4–19] vs. 9 [3–19]) or the mRS score at discharge (3 [1–5] vs. 3 [1–5]). After adjustment for relevant covariates, newly diagnosed AF was not associated with the NIHSS score on admission [adjusted common odds ratio (OR), 0.85; 95% confidence interval (CI), 0.45–1.60] or the mRS score at discharge (adjusted common OR, 1.67; 95% CI, 0.88–3.18). After propensity score matching, newly diagnosed AF was not associated with the NIHSS score on admission (adjusted common OR, 0.91; 95% CI, 0.48–1.73) and the mRS score at discharge (adjusted common OR, 1.77; 95% CI, 0.92–3.43). Conclusion: Stroke severity and in-hospital outcomes in patients with newly diagnosed AF did not differ from those in patients with known AF after adjustment for clinically relevant factors. The importance of detection of latent AF and subsequent anticoagulation in preventing severe stroke should be further emphasized.

Abstract
Early reperfusion after endovascular thrombectomy is associated with an improved outcome in ischemic stroke patients; however, the time dependency in elderly patients remains unclear. We investigated the time–outcome relationships in different age subgroups. Of 2420 patients enrolled in the RESCUE-Japan Registry 2 study, a study based on a prospective registry of stroke patients with acute cerebral large-vessel occlusion at 46 centers, we analyzed the data of 1010 patients with successful reperfusion after endovascular therapy (mTICI of 2b or 3). In 3 age subgroups (< 70, 70 to < 80, and ≥ 80 years), the mRS scores at 90 days were analyzed according to 4 categories of onset-to-reperfusion time (< 180, 180 to < 240, 240 to < 300, and ≥ 300 min). In each age subgroup, the distributions of mRS scores were better with shorter onset-to-reperfusion times. The adjusted common odds ratios for better outcomes per 1-category delay in onset-to-reperfusion time were 0.66 (95% CI 0.55–0.80) in ages < 70 years, 0.66 (95% CI 0.56–0.79) in ages 70 to < 80 years, and 0.83 (95% CI 0.70–0.98) in ages ≥ 80 years. Early reperfusion was associated with better outcomes across all age subgroups. Achieving early successful reperfusion is important even in elderly patients.

Abstract
Background
Thrombosis is a dynamic process, and a thrombus undergoes physical and biochemical changes that may alter its response to reperfusion therapy. This study assessed whether thrombus age influenced reperfusion quality and outcomes after mechanical thrombectomy for cerebral embolism.
Methods
We retrospectively evaluated 185 stroke patients and thrombi that were collected during mechanical thrombectomy at three stroke centers. Thrombi were pathologically classified as fresh or older based on their granulocytes' nuclear morphology and organization. Thrombus components were quantified, and the extent of NETosis (the process of neutrophil extracellular trap formation) was assessed using the density of citrullinated histone H3-positive cells. Baseline patient characteristics, thrombus features, endovascular procedures, and functional outcomes were compared according to thrombus age.
Results
Fresh thrombi were acquired from 43 patients, and older thrombi were acquired from 142 patients. Older thrombi had a lower erythrocyte content (
p
< 0.001) and higher extent of NETosis (
p
= 0.006). Restricted mean survival time analysis revealed that older thrombi were associated with longer puncture-to-reperfusion times (difference: 15.6 minutes longer for older thrombi,
p
= 0.002). This association remained significant even after adjustment for erythrocyte content and the extent of NETosis (adjusted difference: 10.8 minutes, 95% confidence interval [CI]: 0.6–21.1 minutes,
p
= 0.039). Compared with fresh thrombi, older thrombi required more device passes before reperfusion (
p
< 0.001) and were associated with poorer functional outcomes (adjusted common odds ratio: 0.49; 95% CI: 0.24–0.99).
Conclusion
An older thrombus delays reperfusion after mechanical thrombectomy for ischemic stroke. Adding therapies targeting thrombus maturation may improve the efficacy of mechanical thrombectomy.

Abstract
Background:
Thrombus formation is a dynamic process and the structure of thrombus changes with time. We examined the effect of thrombus age on the quality of reperfusion and prognosis in mechanical thrombectomy for acute ischemic stroke.
Methods:
We examined 185 patients who underwent mechanical thrombectomy in 3 stroke centers between January 2015 and December 2019, and pathologically evaluated their retrieved thrombi. Thrombi were classified according to histologically accepted definitions as: fresh, with intact granulocytes; and older, with organization or lytic changes characterized by areas of colliquation necrosis and karyorrhexis of granulocytes. The extent of neutrophil extracellular trap formation (NETosis) in thrombi was assessed on the basis of the density of citrullinated histone H3 positive particles. Baseline characteristics, time to successful reperfusion (eTICI 2b or more), thrombus feature, and functional outcome were compared between the patients with fresh and older thrombi.
Results:
Fresh thrombi were obtained from 43 patients (23%), and older thrombi, from 142 patients (77%). The stroke subtypes and onset-to-puncture time did not significantly differ between the two groups. The erythrocyte content was higher, whereas the density of macrophages and extent of NETosis were lower in the fresh thrombi. Fresh thrombi were associated with shorter time from puncture to recanalization (median, 48 vs. 62 min, P = 0.004; Figure), and fewer passes before reperfusion (median, 1 vs. 2; P < 0.001). In the multivariate analysis, favorable outcome (mRS ≤ 2) was observed more often in patients with fresh thrombi (adjusted OR, 2.76; 95% CI, 1.20-6.32).
Conclusions:
An older thrombus necessitated longer procedure time and more device passes, which deteriorate the functional outcome of patients with acute ischemic stroke. Thrombus maturation may contribute to resistance to mechanical thrombectomy.

Abstract
Objective To compare the impact of intensive blood pressure (BP) lowering right after intracerebral hemorrhage (ICH) on clinical and hematoma outcomes among patients from different geographic locations, we performed a prespecified subanalysis of a randomized, multinational, 2-group, open-label trial to determine the efficacy of rapidly lowering BP in hyperacute ICH (Antihypertensive Treatment of Acute Cerebral Hemorrhage [ATACH]-2), involving 537 patients from East Asia and 463 recruited outside of Asia. Methods Eligible patients were randomly assigned to a systolic BP target of 110 to 139 mm Hg (intensive treatment) or 140 to 179 mm Hg (standard treatment). Predefined outcomes were poor functional outcome (modified Rankin Scale score 4–6 at 90 days), death within 90 days, hematoma expansion at 24 hours, and cardiorenal adverse events within 7 days. Results Poor functional outcomes (32.0% vs 45.9%), death (1.9% vs 13.3%), and cardiorenal adverse events (3.9% vs 11.2%) occurred significantly less frequently in patients from Asia than those outside of Asia. The treatment-by-cohort interaction was not significant for any outcomes. Only patients from Asia showed a lower incidence of hematoma expansion with intensive treatment (adjusted relative risk [RR] 0.56, 95% confidence interval [CI] 0.38–0.83). Both Asian (RR 3.53, 95% CI 1.28–9.64) and non-Asian (RR 1.71, 95% CI 1.00–2.93) cohorts showed a higher incidence of cardiorenal adverse events with intensive treatment. Conclusions Poor functional outcomes and death 90 days after ICH were less common in patients from East Asia than those outside of Asia. Hematoma expansion, a potential predictor for poor clinical outcome, was attenuated by intensive BP lowering only in the Asian cohort. ClinicalTrials.gov Identifier NCT01176565. Classification of Evidence This study provides Class II evidence that, for patients from East Asia with ICH, intensive blood pressure lowering significantly reduces the risk of hematoma expansion.

Abstract
Abstract
Background
Inflammatory status pre-percutaneous coronary intervention (PCI) and post-PCI has been reported not only associated with poor prognosis, but also to impair renal function. Statins reduce cardiovascular events by lowering lipids and have anti-inflammatory impacts, but residual inflammatory risk (RIR) exists. It remains unclear that the synergistic effect of RIR and chronic kidney disease (CKD) on long-term clinical outcome in stable coronary artery disease (CAD) patients undergoing PCI in statin era.
Aim
The aim of this study was to investigate the long-term combined impact of RIR evaluating hs-CRP at follow-up and CKD among stable CAD patients undergoing PCI in statin era.
Methods
This is a single-center, observational, retrospective cohort study assessing consecutive 2,984 stable CAD patients who underwent first PCI from 2000 to 2016. We analyzed 2,087 patients for whom hs-CRP at follow-up (6–9 months later) was available. High residual inflammatory risk was defined as hs-CRP >0.6 mg/L according to the median value at follow up. Patients were assigned to four groups as Group1 (high RIR and CKD), Group2 (low RIR and CKD), Group3 (high RIR and non-CKD) or Group4 (low RIR and non-CKD). We evaluated all-cause death and major adverse cardiac events (MACE), defined as a composite of cardiovascular (CV) death, non-fatal myocardial infarction (MI) and non-fatal stroke.
Results
Of patients (83% men; mean age 67 years), there were 299 (14.3%) patients in group 1, 201 (9.6%) patients in group 2, 754 (36.1%) patients in group 3, and 833 (39.9%) patients in group 4. The median follow-up period was 5.2 years (IQR, 1.9–9.9 years). In total, 189 (frequency, 16.1%) cases of all-cause death and 128 (11.2%) MACE were identified during follow-up, including 53 (4.6%) CV deaths, 27 (2.4%) MIs and 52 (4.8%) strokes. The rate of all-cause death and MACE in group 1 was significantly higher than other groups (p<0.001, respectively). There was a stepwise increase in the incidence rates of all-cause death and MACE. After adjustment for important covariates, the presence of high RIR and/or CKD were independently associated with higher incidence of MACE and higher all-cause mortality. (shown on figure).
Conclusion
The presence of both high RIR and CKD conferred a synergistic adverse effect on the risk for long-term adverse cardiac events in patients undergoing PCI.

Abstract
Abstract
Background
Obesity has the adverse prognostic impact in the general population, whereas paradoxical effect of obesity has been reported in patients with heart failure. Several studies have suggested the same obesity paradox in patients undergoing transcatheter aortic valve implantation (TAVI), however, they included limited number of underweight patients.
Purpose
The aim of this study was to clarify the effect of underweight on outcome following TAVI.
Methods
We retrospectively analyzed consecutive 1,027 patients undergoing TAVI between April 2010 and June 2019. The patients were categorized according to body mass index (BMI) as follows: underweight (<18.5 kg/m2, n=150), normal weight (18.5 to 25 kg/m2, n=657), and overweight (>25 kg/m2, n=220). BMI was defined as body weight (kg) divided by the square of body height (m) measured at the hospital admission. We compared the short- and mid-term outcome after TAVI among three groups, and all clinical events were accordance with Valve Academic Research Consortium-2 criteria.
Results
Underweight patients were more often female, and had a higher prevalence of hypertension, dyslipidemia, peripheral artery disease, anemia, and hypoalbuminemia. They also presented lower ejection fraction, smaller aortic valve area, and higher surgical risk score. In procedural findings, device unsuccess and major vascular complication more occurred in underweight patients, but 30-day mortality was equivalent among three groups. The mid-term survival of the underweight was inferior to the other two groups (figure).In the multivariate analysis, female (hazard ratio [HR] 0.52, 95% confidence interval [CI] 0.37–0.73, P=0.0002), atrial fibrillation (HR 2.22, 95% CI 1.56–3.17, P<0.0001), albumin value (HR 0.37 per 1-g/dl increase, 95% CI 0.25–0.55, P<0.0001), Society of Thoracic Surgeons score (HR 1.06 per 1% increase, 95% CI 1.02–1.06, P=0.0039), 30-day combined endpoint (HR 2.12, 95% CI 1.33–3.38, P=0.0017), and underweight (HR 1.59, 95% CI 1.04–2.37, P=0.026) were associated with the survival after TAVI.
Conclusion
The underweight had a worse mid-term prognosis, representing the obesity paradox in the TAVI population.

Abstract
OBJECTIVES As the number of patients with left ventricular assist device (LVAD) implantation has been increasing, treatment of LVAD-related ischemic stroke is becoming a critical issue. We sought to clarify the features of mechanical thrombectomy in LVAD-related stroke with large vessel occlusion. METHODS In a multi-center, retrospective case-control study, we compared 20 LVAD-related strokes with 33 non-LVAD strokes, all of which had large vessel occlusion in the anterior circulation treated with mechanical thrombectomy. A comparative histopathological examination of the retrieved thrombi was also performed. RESULTS Successful reperfusion was achieved in 75% of the LVAD-related strokes. The time from onset to reperfusion was similar to that of non-LVAD strokes, but the total number of device passes required for reperfusion (median, 2.5 versus 1, P = 0.01) and the incidences of post-procedural parenchymal and subarachnoid hemorrhage (25% versus 3%, P = 0.02 and 55% versus 15%, P = 0.01, respectively) were higher in LVAD-related strokes. Symptomatic intracranial hemorrhage occurred in 4 patients (20%) with LVAD-related strokes. The histopathological analysis revealed that the ratio of erythrocyte components was significantly lower in thrombi retrieved from patients with LVAD-related stroke than in those with non-LVAD stroke (19 ± 6% versus 41 ± 17%, P = 0.01). CONCLUSIONS Mechanical thrombectomy is feasible in patients with LVAD-related stroke. However, repetitive device passes are needed to achieve successful reperfusion mainly because of the structurally organized thrombi, and the higher risk of hemorrhagic complications should be considered, while offering this therapeutic alternative.

Abstract
BACKGROUND AND PURPOSE Evidence regarding sex differences in clinical outcomes and treatment effect following intracerebral hemorrhage is limited. Using the ATACH-2 trial (Antihypertensive Treatment in Intracerebral Hemorrhage-2) data, we explored whether sex disparities exist in outcomes and response to intensive blood pressure (BP)-lowering therapy. METHODS Eligible intracerebral hemorrhage subjects were randomly assigned to intensive (target systolic BP, 110-139 mm Hg) or standard (140-179 mm Hg) BP-lowering therapy within 4.5 hours after onset. Relative risk of death or disability corresponding to the modified Rankin Scale score of 4 to 6 was calculated, and interaction between sex and treatment was explored. RESULTS In total, 380 women and 620 men were included. Women were older, more prescribed antihypertensive drugs before onset, and had more lobar intracerebral hemorrhage than men. Hematoma expansion was observed less in women. After multivariable adjustment, the relative risk of death or disability in women was 1.19 (95% CI, 1.02-1.37, P=0.023). The relative risk of death or disability between intensive versus standard BP-lowering therapy was 0.91 (95% CI, 0.74-1.13) in women versus 1.13 (95% CI, 0.92-1.39) in men (P for interaction=0.11), with inconclusive Gail-Simmon test (P=0.16). CONCLUSIONS Women had a higher risk of death or disability following intracerebral hemorrhage. The benefit of intensive BP-lowering therapy in women is inconclusive, consistent with the overall results of ATACH-2. Registration: URL: https://www.clinicaltrials.gov.

Abstract
Atherosclerosis - the pathophysiological mechanism shared by most cardiovascular diseases - can be directly or indirectly assessed by a variety of clinical tests including measurement of carotid intima-media thickness, carotid plaque, -ankle-brachial index, pulse wave velocity, and coronary -artery calcium. The Prospective Studies of Atherosclerosis -(Proof-ATHERO) consortium (https://clinicalepi.i-med.ac.at/research/proof-athero/) collates de-identified individual-participant data of studies with information on atherosclerosis measures, risk factors for cardiovascular disease, and incidence of cardiovascular diseases. It currently comprises 74 studies that involve 106,846 participants from 25 countries and over 40 cities. In summary, 21 studies recruited participants from the general population (n = 67,784), 16 from high-risk populations (n = 22,677), and 37 as part of clinical trials (n = 16,385). Baseline years of contributing studies range from April 1980 to July 2014; the latest follow-up was until June 2019. Mean age at baseline was 59 years (standard deviation: 10) and 50% were female. Over a total of 830,619 person-years of follow-up, 17,270 incident cardiovascular events (including coronary heart disease and stroke) and 13,270 deaths were recorded, corresponding to cumulative incidences of 2.1% and 1.6% per annum, respectively. The consortium is coordinated by the Clinical Epidemiology Team at the Medical University of Innsbruck, Austria. Contributing studies undergo a detailed data cleaning and harmonisation procedure before being incorporated in the Proof-ATHERO central database. Statistical analyses are being conducted according to pre-defined analysis plans and use established methods for individual-participant data meta-analysis. Capitalising on its large sample size, the multi-institutional collaborative Proof-ATHERO consortium aims to better characterise, understand, and predict the development of atherosclerosis and its clinical consequences.

Abstract
Objectives: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary small vessel disease, with reported frequencies of 2-5/100,000 individuals. Recently, it has been reported that some patients with NOTCH3 gene mutations show atypical clinical symptoms of CADASIL. Assuming that CADASIL is underdiagnosed in some cases of lacunar infarction, this study was designed to examine the prevalence of NOTCH3 gene mutations in the patients at highest risk who were admitted for lacunar infarctions. Methods: From January 2011 to April 2018, 1,094 patients with lacunar infarctions were admitted to our hospital, of whom 31 patients without hypertension but with white matter disease (Fazekas scale 2 or 3) were selected and genetically analyzed for NOTCH3 gene mutations (Phase 1). Furthermore, 54 patients, who were 60 years or younger, were analyzed for NOTCH3 mutations (Phase 2). NOTCH3 exons 2–24, which encode the epidermal growth factor-like repeat domain of the NOTCH3 receptor, were analyzed for mutations by direct sequencing of genomic DNA. Results: Three patients presented NOTCH3 p.R75P mutations: two in the Phase 1 and one in the Phase 2 cohort. Among patients aged 60 years or younger and those without hypertension but with moderate-to-severe white matter lesions, the carrier frequency of p.R75P was 3.5% (3/85), which was significantly higher than that in the Japanese general population (4.7KJPN) (odds ratio [95% CI] = 58.2 [11.6–292.5]). All three patients with NOTCH3 mutations had family histories of stroke, and the average patient age was 51.3 years. All three patients also showed white matter lesions in the external capsule but not in the temporal pole. The CADASIL and CADASIL scale-J scores of the three patients were 6, 17, 7 (mean, 10.0) and 13, 20, 10 (mean, 14.3), respectively. Conclusion: Among patients hospitalized for lacunar infarctions, the p.R75P prevalence may be higher than previously estimated. The NOTCH3 p.R75P mutation may be underdiagnosed in patients with early-onset lacunar infarctions due to the atypical clinical and neuroimaging features of CADASIL. Early-onset, presence of family history of stroke, external capsule lesions, and absence of hypertension may help predict underlying NOTCH3 mutations despite no temporal white matter lesions.

Abstract
BACKGROUND Chemotherapy may be a cause of cancer-associated stroke, but whether it increases stroke risk remains uncertain. We investigated how chemotherapy affects stroke risk in cancer patients. METHODS Of 27,932 patients in a hospital-based cancer registry (which contains clinical data on all patients treated for cancer at Osaka University Hospital) screened between 2007 and 2015, medical records of 19,006 patients with complete data were investigated. A validated algorithm was used to identify stroke events within 2 years of cancer diagnosis. Patients were divided based on whether their initial treatment plan included chemotherapy. The association between chemotherapy and stroke was analyzed using the Kaplan-Meier method and stratified Cox regression. RESULTS Of 19,006 patients, 5,887 (31%) were in the chemotherapy group. Stroke occurred in 44 (0.75%) and 51 (0.39%) patients in the chemotherapy and nonchemotherapy group, respectively. Kaplan-Meier curve analysis showed that patients in the chemotherapy group had a higher stroke risk than those in the nonchemotherapy group (hazard ratio [HR] 1.84; 95% confidence interval [CI] 1.23-2.75). However, this difference was insignificant after adjustment for cancer status using inverse probability of treatment weighting with propensity scores (HR 1.20; 95% CI 0.76-1.91). Similarly, in the stratified Cox regression model, chemotherapy was not associated with stroke after adjustment for cancer status (HR 1.26; 95% CI 0.78-2.03). CONCLUSION In our study, the elevated stroke risk in cancer patients who received chemotherapy was presumably due to advanced cancer stage; chemotherapy was not associated with the increased risk of stroke.

Abstract
BACKGROUND Neurological deterioration (ND) has a major influence on the prognosis of intracerebral hemorrhage (ICH); however, factors associated with ND occurring after 24 h of ICH onset are unknown. METHODS We performed exploratory analyses of data from the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 trial, which compared intensive and standard blood pressure lowering treatment in ICH. NDs were captured on the adverse event case report form. Logistic regression analysis was performed to examine the independent predictors of late ND. RESULTS Among 1,000 participants with acute ICH, 82 patients (8.2%) developed early ND (≤24 h), and 64 (6.4%) had late ND. Baseline hematoma volume (adjusted OR [aOR] per 1-cm3 increase 1.04, 95% CI 1.02-1.06, p < 0.0001), hematoma volume increase in 24 h (aOR 2.24, 95% CI 1.23-4.07, p = 0.008), and the presence of intraventricular hemorrhage (IVH; aOR 2.38, 95% CI 1.32-4.29, p = 0.004) were independent predictors of late ND (vs. no late ND). Late ND was a significant risk factor for poor 90-day outcome (OR 3.46, 95% CI 1.82-6.56). No statistically significant difference in the incidence of late ND was noted between the 2 treatment groups. CONCLUSIONS Initial hematoma volume, early hematoma volume expansion, and IVH are independent predictors of late ND after ICH. Intensive reduction in the systolic blood pressure level does not prevent the development of late ND.

Abstract
OBJECTIVE To determine whether frequent premature atrial contractions (PAC) predict atrial fibrillation (AF) in cryptogenic stroke patients, we analyzed the association between frequent PACs in 24-h Holter electrocardiogram recording and AF detected by insertable cardiac monitoring (ICM). METHODS We retrospectively analyzed a database of 66 consecutive patients with cryptogenic stroke who received ICM implantation between October 2016 and March 2018 at 5 stroke centers. We included the follow-up data until June 2018 in this analysis. We defined frequent PACs as the upper quartile of the 66 patients. We analyzed the association of frequent PACs with AF detected by ICM. RESULTS Frequent PACs were defined as >222 PACs per a 24-h period. The proportion of patients with newly detected AF by ICM was higher in patients with frequent PACs than those without (50% [8/16] vs. 22% [11/50], p < 0.05). Frequent PACs were associated with AF detection and time to the first AF after adjustment for CHADS2 score after index stroke, high plasma -B-type natriuretic peptide (BNP; >100 pg/mL) or serum -N-terminal pro-BNP levels (>300 pg/mL), and large left atrial diameter (≥45 mm). CONCLUSION High frequency of PACs in cryptogenic stroke may be a strong predictor of AF detected by ICM.

Abstract
Introduction:
Chemotherapy may be a cause of cancer-associated stroke, but whether it increases stroke risk remains uncertain. We aimed to clarify the impact of chemotherapy on stroke risk in cancer patients.
Methods:
We investigated 27,932 patients enrolled in a hospital-based cancer registry at Osaka University Hospital between 2007 and 2015. The registry collects clinical data, including cancer status (site and stage), on all patients treated for cancer. Of them, 19,006 patients with complete data were included. A validated algorithm was used to identify stroke events within 2 years of cancer diagnosis. Patients were divided based on whether their initial treatment plan included chemotherapy. The association between chemotherapy and stroke was analyzed using the Kaplan-Meier method and stratified Cox regression.
Results:
Of the 19,006 patients, 5,887 (31%) patients were in the chemotherapy group. Non-targeted chemotherapy was used in 5,371 patients. Stroke occurred in 44 patients (0.75%) in the chemotherapy group and 51 patients (0.39%) in the no-chemotherapy group. Kaplan-Meier curve analysis showed that patients in the chemotherapy group had a higher stroke risk than patients in the no-chemotherapy group (HR 1.84; 95% CI 1.23-2.75; Figure [A]). However, this difference was insignificant after adjustment for cancer status using inverse probability of treatment weighting with propensity scores (HR 1.20; 95% CI 0.76-1.91; Figure [B]). Similarly, in the stratified Cox regression model, chemotherapy was not associated with stroke after adjustment for cancer status (HR 1.26; 95% CI 0.78-2.03). These findings were consistent with analysis wherein the effect of chemotherapy was treated as a time-dependent covariate (HR 1.02; 95% CI 0.55-1.88).
Conclusions:
In this population, the elevated stroke risk in cancer patients who received chemotherapy was presumably due to advanced cancer stage; chemotherapy was not associated with the increased risk of stroke.

Abstract
Background and Purpose- Carotid artery stenosis is common in the elderly and contributes to cognitive impairment and dementia. Cortical cerebral microinfarcts (CMIs) play an important role in vascular cognitive impairment and dementia. We aimed to investigate the association between CMIs on 3T magnetic resonance imaging and clinical and radiological features, including plaque morphology, and cognitive function in patients with carotid stenosis. Methods- Eighty-nine patients with >30% carotid stenosis on ultrasound were prospectively enrolled, and underwent brain and carotid artery magnetic resonance imaging. CMIs were rated according to predetermined criteria based on 3D-double inversion recovery and fluid-attenuated inversion recovery images. Results- CMIs were identified in 26 patients (29%; median number 0, range 0-9). Poisson regression models adjusted for age and sex revealed that CMIs were associated with intraplaque hemorrhage (rate ratio, 1.95; 95% CI, 1.26-3.18), lacunar infarcts (rate ratio, 1.54; 95% CI, 1.00-2.44), and cortical infarcts (rate ratio, 3.22; 95% CI, 2.20-5.00). These associations were also observed in asymptomatic patients (n=64). Of 81 patients with unilateral carotid stenosis, the prevalence and number of CMIs were significantly higher in the hemisphere ipsilateral to the carotid stenosis than in the contralateral hemisphere ( P=0.005 and P<0.001, respectively). The presence of CMIs was associated with poor cognitive function. Conclusions- Our results indicate that vulnerable carotid plaque increases the risk of CMIs and subsequent cognitive impairment. Carotid atherosclerosis could be a potential therapeutic target for cognitive impairment.

Abstract
Abstract
Background
The usefulness of fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) evaluation has been confirmed in the determination of revascularization of coronary artery disease. When FFR≤0.8 and iFR≤0.89 were regarded as the criteria for positivity, the discordance was noted in approximately 20%, but this cause has not been well established.
Purpose
The purpose of this study was to investigate the patient background and features on coronary CT angiography (CCTA) showing the discordance between FFR≤0.8 and iFR≤0.89.
Methods
The subjects were consecutive 85 cases with 108 vessels in which stenosis of 30–90% was detected at one vessel of at least 2mm or more in the major epicardial vessels and FFR and iFR was performed within subsequent 90 days, among suspected cases of coronary arterial diseases which underwent CCTA. The factors showing the discordance between FFR and iFR (patient background, coronary artery calcification score, high risk plaque features on CCTA (positive remodeling, low attenuation plaque), plaque characteristics by a plaque analysis software using a new algorithm called labeling method (vessel volume, plaque volume, lumen volume, plaque length, maximum plaque burden, necrotic core area, fibrous area and calcium area) were evaluated using logistic regression analysis on per-patient and per-vessel basis.
Results
There were no significant both FFR and iFR positive definite factors on per-patient basis. The lumen volume/vessel volume (OR: 0.93, 95% CI: 0.88–0.98, P=0.0032) (OR: 0.90, 95% CI: 0.85–0.95, P<0.0001),minimum lumen area (MLA) (OR: 0.59, 95% CI: 0.41–0.85, P=0.0006) (OR: 0.64, 95% CI: 0.44–0.92, P=0.0047), the plaque volume/vessel volume (OR: 1.05, 95% CI: 1.01–1.10, P=0.0114) (OR: 1.09, 95% CI: 1.04–1.15, P=0.0002) and maximum plaque burden (OR: 1.08, 95% CI: 1.01–1.15, P=0.0095) (OR: 1.06, 95% CI: 1.00–1.13, P=0.0406) were significant both FFR and iFR positive definite factors on per-vessels basis. Discordance between FFR≤0.8 and iFR≤0.89 was observed in 23 vessels (21.3%) of 19 patients. In FFR positive and iFR negative group (15 vessels, 13.9%), positive remodeling (PR) (OR: 4.38, 95% CI: 1.13–17.00, P=0.0294) was only significant predictor. In FFR negative and iFR positive group, there was no significant predictors.
Conclusions
In both FFR and iFR, only lumen volume /vessel volume, MLA, plaque volume/vessel volume and plaque burden were significant positive definite factors. As for the discordance between FFR and iFR, PR is significant predictor in FFR positive and iFR negative group.

Abstract
Modified Rankin Scale (mRS) is widely used as an indicator of physical disability after the onset of stroke and a main evaluation scale in clinical stroke trials but sometimes has discrepancies among raters. We designed a Japanese version of simplified mRS questionnaire (J-RASQ) to evaluate mRS using closed question to assess the difference from the original. Currently there are no Japanese version of mRS questionnaire and its validity and reliability assessment has been warranted. Patients with planned visit to our hospital between 60 and 120 days after the onset of cerebral hemorrhage or infarction between August 2017 and March 2018 were recruited. J-RASQ was distributed before the outpatient visit to stroke patients, families or caregivers, and response was obtained. Thereafter, outpatient attending physicians qualified as stroke or neurological specialists evaluated mRS according to the Japanese version of guidance scheme for mRS. Subsequently, 130 patients (mean age, 72 ± 12 years old) were enrolled, and the difference between the two scale scores (mRS vs. J-RASQ) were statistically examined by the κ statistic and the weighted κ statistic. The κ statistic was 0.42 (95% CI, 0.31-0.52), and the weighted κ statistic calculated taking into account the extent of disagreement was 0.78 (95% CI, 0.70-0.86). We conclude that the J-RASQ appears to have decent reliability and is similar to the existing mRS.

Abstract
Background and Purpose- The ring finger protein 213 gene ( RNF213) is a susceptibility gene for moyamoya disease and large-artery ischemic stroke in East Asia. We examined the prevalence and correlates of the RNF213 p.R4810K variant in patients with early-onset ischemic stroke in a Japanese single-center cohort. Methods- We analyzed 70 early-onset stroke patients with intracranial arterial stenosis who developed a noncardioembolic stroke or transient ischemic attack from 20 to 60 years of age. Patients with moyamoya disease were excluded. Results- The RNF213 p.R4810K variant was found in 17 patients (24%), and more often in women than men (38% versus 16%, odds ratio 3.3; 95% CI, 1.1-10.2, P=0.04). The variant was identified in 35% of patients with stenosis in the M1 segment of the middle cerebral artery or the A1 segment of the anterior cerebral artery (odds ratio, 25.0; 95% CI, 1.4-438; P<0.01) but in only one patient (9%) with intracranial posterior circulation stenosis. Conventional atherosclerotic risk factors did not differ between variant carriers and noncarriers. Conclusions- The RNF213 p.R4810K variant is common in early-onset ischemic stroke with anterior circulation stenosis in Japan. Further investigation of the RNF213 gene will provide new insights into pathogenetic mechanisms of early-onset stroke.

Abstract
Introduction:
Left ventricular assist device (LVAD) implantation improves the prognosis of patients with severe heart failure; however, the potential impact of long-term LVAD support on the brain remains unclear. The aim of this case-control study was to examine the characteristics of brain MRI in patients after long-term LVAD support.
Methods:
We retrospectively reviewed consecutive adult patients who underwent continuous-flow LVAD implantation in our hospital from 2010 to 2017, and those who underwent brain MRI after successful LVAD explantation were enrolled in this study. Age- and sex-matched control subjects (1:1) were selected from a pool of normal subjects who underwent MRI examination for screening purposes. The number and location of cerebral microbleeds (CMBs) and superficial siderosis, and the severity of white matter hyperintensity (WMH) and cerebral atrophy were compared between LVAD patients and controls.
Results:
We enrolled 49 LVAD patients and 49 controls. In LVAD patients, cardiomyopathy (84%) was the most common underlying heart disease. Heart transplantation was performed in 46 patients (94%) and 3 removed LVAD due to myocardial recovery. The median age was 41 years (range 19-66), and the median LVAD support time was 32 months (4-52). Nineteen patients developed symptomatic stroke (10 ischemic and 10 hemorrhagic) during LVAD support. Except for one, almost all (98%) LVAD patients had one or more CMBs, and the number of CMBs was much higher in the LVAD patients (mean, IQR: 7, 3-11 vs 0, 0-0: p<0.001) than controls. Superficial siderosis was positive in 15 (31%) of LVAD patients, but not in controls. The severity of WMH was significantly higher both in deep subcortical (p=0.01), and periventricular region (p=0.04) than controls. In quantitative analyses of cerebral atrophy, bicaudate ratio (0.105±0.023 vs 0.089±0.019: p<0.001) and cella-media index (0.160±0.033 vs 0.141±0.024: p<0.001) were significantly higher in LVAD patients than controls.
Conclusions:
Patients after long-term LVAD support showed a high prevalence of CMBs and superficial siderosis, and more severe WMH and cerebral atrophy compared to age- and sex-matched controls. Long-term LVAD support may cause cerebral small vessel disease.

Abstract
Background and purpose:
RING finger protein 213 (
RNF213
) gene is strongly associated with intracranial arterial stenosis as well as Moyamoya disease and its dysregulation is known to impair cerebral perfusion in rodents. We thus investigated the relationship between
RNF213
p.R4810K (c.14429G>A) variant and the anatomical variations of the circle of Willis in cerebrovascular disease.
Methods:
We consecutively enrolled non-cardioembolic stroke or transient ischemic attack patients with (n = 20) or without (n = 80)
RNF213
p.R4810K (c.14429G>A) variation from those who participated in the biobank of our Institute over the past 2 years. Moyamoya disease cases were excluded. We evaluated anatomical variations of the vessels constituting the circle of the Willis, namely, intracranial internal carotid artery, anterior communicating artery (AcomA), anterior cerebral artery A1 segment, posterior communicating artery (PcomA), posterior cerebral artery P1 segment, and middle cerebral artery M1 segment, using maximum intensity projection of a time-of-flight magnetic resonance angiography collected at 3 Tesla.
Results:
The
RNF213
p.R4810K (c.14429G>A) variant carrier had higher frequency of focal narrowing of the M1 segment compared to the non-carrier (50% vs 10%, p<0.01) and an absence of AcomA (15% vs 3.7%, p=0.09). By contrast, unexpectedly, unilateral or bilateral absence of PcomA was significantly less frequent (25% vs 61%, p<0.01). Multivariate analysis adjusted for age and sex showed that the variant carrier state was independently associated with unilateral or bilateral presence of PcomA (odds ratio (OR) 4.44, 95% confidence interval (CI) 1.01 - 20.6, p<0.05) and focal M1 narrowing (OR 3.30, 95% CI 0.82 - 12.6, p=0.09).
Conclusions:
The
RNF
213 p.R4810K (c.14429G>A) variant carrier showed higher frequency of arteriopathy in the anterior circulation accompanied by higher patency rate of PcomA. In the variant carrier, dysplasia of the anterior circulation arteries may lead to compensatory collateral flow from posterior to anterior circulation through PcomA.

Abstract
Background and Purpose:
There is still uncertainty about the underlying mechanism of cortical microinfarcts in patients with carotid artery stenosis. We assessed the association between cortical microinfarcts (CMIs) on 3T MRI and imaging features of carotid and brain MRI.
Methods:
Eighty-nine patients with >50% carotid artery stenosis on carotid ultrasound were prospectively included, and underwent both carotid and brain MRI. CMIs were rated according to pre-determined criteria based on double inversion recovery and 3D FLAIR images.
Results:
We identified 69 CMIs in 26 (29%) patients. Multivariate-adjusted models showed CMIs were associated with intraplaque hemorrhage, and cortical infarct but not with severe stenosis (>70%) or markers of small vessel disease (SVD) such as white matter hyperintensities and cerebral microbleeds. Among 81 patients with unilateral carotid artery stenosis, 18 patients (22%) had 52 CMIs in ipsilateral hemisphere, while 6 patients (6%) had 9 CMIs in contralateral hemisphere. The number of CMIs were significantly higher in the ipsilateral side than in the contralateral side (
P
= 0.005).
Conclusions:
CMIs were associated with intraplaque hemorrhage, cortical infarct, and carotid artery stenosis. These findings suggest artery-to-artery emboli might be the underlying cause of CMIs in patients with carotid artery stenosis.
