Abstract
INTRODUCTION Intracranial large artery disease (ICLAD) is a common cause of ischaemic stroke and is associated with the risk of recurrent vascular events in the short term. We compared the incidence of various long-term vascular outcomes between ischaemic stroke patients with and without ICLAD. METHODS This was a longitudinal observational study of acute ischaemic stroke patients who were followed up serially for recurrent stroke, myocardial infarction or vascular death up to a median of 86 months. Transcranial colour-coded Doppler was used in the diagnosis of ICLAD. RESULTS Among the 581 ischaemic stroke patients studied (median age 63 ± 11 years, male 71%), 354 (60.9%) had ICLAD. In regression analyses adjusting for covariates, patients with ICLAD were more likely to have long-term composite vascular outcomes (hazard ratio [HR] 1.44, 95% confidence interval [CI] 1.02-2.03, P = 0.041), myocardial infarction (HR 2.89, 95% CI 1.71-4.91, P < 0.001) and vascular death (HR 3.52, 95% CI 1.67-7.52, P = 0.001) but not recurrent stroke (HR 1.10, 95% CI 0.72-1.70, P = 0.652), at a median of 86 months as compared to patients without ICLAD. CONCLUSION Our findings of poor prognostic impact of ICLAD on long-term recurrent vascular events after ischaemic stroke provide evidence for the need of specific, emphasised screening and secondary prevention, especially for coronary artery disease in this high-risk group.

Development and validation of a clinical prediction model for ischemic stroke recurrence after successful stent implantation in symptomatic intracranial atherosclerotic stenosis. J Clin Neurosci 2024; 123:137-147. [PMID: 38574685 DOI: 10.1016/j.jocn.2024.03.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/18/2024] [Accepted: 03/28/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE This study aimed to analyze the risk factors for recurrent ischemic stroke in patients with symptomatic intracranial atherosclerotic stenosis (ICAS) who underwent successful stent placement and to establish a nomogram prediction model. METHODS We utilized data from a prospective collection of 430 consecutive patients at Jining NO.1 People's Hospital from November 2021 to November 2022, conducting further analysis on the subset of 400 patients who met the inclusion criteria. They were further divided into training (n=321) and validation (n=79) groups. In the training group, we used univariate and multivariate COX regression to find independent risk factors for recurrent stroke and then created a nomogram. The assessment of the nomogram's discrimination and calibration was performed through the examination of various measures including the Consistency index (C-index), the area under the receiver operating characteristic (ROC) curves (AUC), and the calibration plots. Decision curve analysis (DCA) was used to evaluate the clinical utility of the nomogram by quantifying the net benefit to the patient under different threshold probabilities. RESULTS The nomogram for predicting recurrent ischemic stroke in symptomatic ICAS patients after stent placement utilizes six variables: coronary heart disease (CHD), smoking, multiple ICAS, systolic blood pressure (SBP), in-stent restenosis (ISR), and fasting plasma glucose. The C-index (0.884 for the training cohort and 0.87 for the validation cohort) and the time-dependent AUC (>0.7) indicated satisfactory discriminative ability of the nomogram. Furthermore, DCA indicated a clinical net benefit from the nomogram. CONCLUSIONS The predictive model constructed includes six predictive factors: CHD, smoking, multiple ICAS, SBP, ISR and fasting blood glucose. The model demonstrates good predictive ability and can be utilized to predict ischemic stroke recurrence in patients with symptomatic ICAS after successful stent placement.

Abstract
BACKGROUND Risk factors and functional outcome of hemorrhagic transformation (HT) after mechanical thrombectomy (MT) are to be elucidated in patients with acute large vessel occlusion stroke. METHODS We retrospectively analyzed data from 88 patients who underwent MT treatment. Independent risk factors of hemorrhagic infarction (HI), parenchymal hematoma (PH) and symptomatic intracranial hemorrhage (sICH) were implemented to determine. Association between HI, PH, sICH and mortality at 90 days after treatment were analyzed. RESULTS Of 88 patients, 44.3%had HT (N.=39). 64.1% had HI (N.=25), 35.9% had PH (N.=14) and 12.5% had sICH (N.=11). Independent risk factors for HI were associated with higher NIHSS Score (OR 1.190; 95% CI 1.073~1.319, P=0.001, per 1 score increase), history of coronary heart disease (OR 4.645; 95% CI 1.092~19.758, P=0.038), and use of intravenous thrombolysis (OR 3.438; 95% CI 1.029~11.483, P=0.045). Independent risk factors for PH were associated with higher NIHSS Score (OR 1.227; 95% CI 1.085~1.387, P=0.001, per 1 score increase) and history of oral antiplatelet and/or anticoagulation drugs (OR 6.694; 95% CI 1.245~35.977, P=0.027). Independent risk factors for sICH were associated with higher NIHSS Score (OR 1.393; 95% CI 1.138~1.704, P=0.001, per 1 score increase), increased systolic blood pressure (OR 1.061; 95% CI 1.006~1.120, P=0.030, per 1 mmHg increase) and history of coronary heart disease (OR 13.699; 95% CI 1.019~184.098, P=0.048). Patients who had PH were more likely to cause mortality at 90 days (OR 10.15; 95% CI 1.455~70.914, P=0.019). CONCLUSIONS Higher NIHSS Score was associated with HI, PH, and sICH. History of coronary heart was associated with HI and sICH. Use of intravenous thrombolysis was associated with HI. History of oral antiplatelet and/or anticoagulation drugs was associated with PH. Increased systolic blood pressure was associated with sICH. PHs was remarkably associated with mortality at 90 days.

Abstract
Background Atherosclerosis of brain- and heart-supplying arteries (BHAs) are risk indicators for patients with ischemic stroke, but the atherosclerosis burden (AB) of intracranial, cervical, aortic, and coronary arteries in each and in total have not been simultaneously evaluated, and the associations with vascular risk remain unknown. Methods and Results With computed tomography angiography, single-territory AB was triple ranked on the basis of the number of arterial segments with a significant atherosclerotic lesion. The total AB (TAB) of BHAs was triple ranked on the basis of the number of arterial territories with a significant atherosclerotic lesion, or according to the sum of 4 single-territory AB rank-scores. After a 12-month follow-up of 395 patients with ischemic stroke, a composite outcome of ischemic stroke, myocardial infarction, and vascular death occurred in 10.9%. The single-territory AB of intracranial, cervical, aortic, and coronary arteries showed distinct strata patterns and different associations with vascular risk. The score-based TAB of BHAs predicted vascular risk (crude hazard ratios [95% CIs]: per level increase, 2.35 [1.54-3.58]; median versus low, 3.37 [1.45-7.82]; high versus low, 6.00 [2.36-15.24]) independently of vascular risk factors and single-territory AB, providing more prognostic information than the TAB of BHAs measured by the number of significantly atherosclerotic territories. Vascular events occurred in 3.0%, 13.6%, and 22.6% of patients in the low (41.8%), median (44.8%), and high (13.4%) strata of the score-based TAB of BHAs, respectively. Conclusions The single-territory AB of intracranial, cervical, aortic, or coronary arteries might be not reliable for vascular risk stratification in patients with ischemic stroke, and evaluating the TAB of BHAs by quantitatively integrating the single-territory AB is advisable.

Abstract
Early neurological deterioration (END) is associated with a poor survival after mechanical thrombectomy (MT) in acute ischemic stroke (AIS). To assess risk factors and functional outcomes of END after MT in patients, we analyzed data from 79 patients who received MT with large-vessel occlusion. END after MT in patients is defined as an increase of two points or more in the National Institute of Health Stroke Scale (NIHSS) score, compared with the best neurological status within 7 days. The mechanism of END can be classified into: AIS progression, sICH, and encephaledema. A total of 32 AIS patients (40.5%) had END after MT. Risk factors for END after MT included: history of oral antiplatelet and/or anticoagulation drugs before MT (OR = 9.56,95% CI = 1.02-89.57), higher NIHSS score when admitted to hospital (OR = 1.24, 95% CI = 1.04-1.48), under the subtype of atherosclerotic stroke (OR = 17.36, 95% CI = 1.51-199.56), ASITN/SIR< 2 (OR = 15.78, 95% CI = 1.65-151.26), and prolonged period from AIS onset to the first revascularization (OR = 1.01, 95% CI = 1.00-1.02). AIS patients who had END at early stages were more likely to experience poor outcomes (Modified Rankin Scale [mRS] >2) at 90 days after MT (OR = 6.829, 95% CI = 1.573-29.655). Thus, AIS patients who had experienced END at early stages were more likely to have poor outcomes (mRS >2) at 90 days after MT, and the risk factors of END were connected to the mechanism of END.

Abstract
AIMS The basilar artery (BA) geometry and plaque characteristics may play an important role in the development of atherosclerosis. This study was performed to explore the relationship between the mid-BA angle and plaque characteristics and its effect on pontine infarction using high-resolution magnetic resonance imaging and three-dimensional time-of-flight magnetic resonance angiography. METHODS In total, 77 patients with BA plaques were included in this study. According to the presence of acute pontine infarction on diffusion-weighted imaging, the patients were divided into a pontine infarction group and pontine non-infarction group. The mid-BA angle, plaque burden, stenosis ratio, positive remodeling, and intraplaque hemorrhage were evaluated to investigate their effects on stroke. RESULTS The pontine infarction group had a greater plaque burden, stenosis ratio, positive remodeling, and mid-BA angle than the pontine non-infarction group. The correlation between the plaque burden and mid-BA angle was the highest (r=0.441, P<0.001). Multivariate logistic regression analysis showed that the plaque burden (odds ratio, 1.164; 95% confidence interval, 1.093-1.241; P<0.001) was an independent risk factor for pontine infarction. CONCLUSION The mid-BA angle may increase the incidence of pontine infarction by increasing the plaque burden.

Abstract
Background Intracranial atherosclerotic stenosis (ICAS) is a primary cause of ischemic stroke. In addition to dyslipidemia, inflammation has been recognized as a potential pathogenesis of atherosclerosis. It remains unknown whether there is a link between transthyretin and ICAS as an inflammatory index. Methods Consecutive patients with acute ischemic stroke admitted to the Second Affiliated Hospital of Wenzhou Medical University between January 2019 and June 2020 were retrospectively analyzed. Blood samples were collected from all patients within 24 h of admission to detect their serum transthyretin levels. ICAS was defined as at least one intracranial artery stenosis on vascular examination with a degree of stenosis ≥50%. Multivariable logistic regression analysis was used to identify independent factors associated with ICAS. Restricted cubic spline models were used to depict patterns in the association between serum transthyretin levels and ICAS. Results In total, 637 patients with acute ischemic stroke were included in this study, of whom 267 (41.9%) had ICAS. Compared with the patients without ICAS, serum transthyretin levels in patients with ICAS were significantly lower (226.3 ± 56.5 vs. 251.0 ± 54.9 mg/L; p < 0.001). After adjusting for potential confounders, patients in the lowest tertile showed a significant increase in ICAS compared to those in the highest tertile (odds ratio, 1.85; 95% confidence interval, 1.12–3.05; p = 0.016). This negative linear association is also observed in the restricted cubic spline model. However, this association may only be observed in men. Age, National Institutes of Health Stroke Scale score, hemoglobin A1c level, and low-density lipoprotein cholesterol level were independently associated with ICAS. Conclusions Decreased serum transthyretin levels are associated with a more severe ICAS burden in patients with acute ischemic stroke. Our findings suggest that transthyretin may play a role in the pathogenesis of ICAS and provide insight into the control of inflammation for the treatment of ICAS.

Abstract
The formation of atherosclerotic plaques is the root cause of various cardiovascular diseases (CVDs). Effective CVD interventions thus call for precise identification of the plaques to aid clinical assessment, diagnosis, and treatment of such diseases. In this study, we introduce a dual-target sequentially activated fluorescence reporting system, termed in-sequence high-specificity dual-reporter unlocking (iSHERLOCK), to precisely identify the atherosclerotic plaques in vivo and ex vivo. ISHERLOCK was achieved by creating a three-in-one fluorescent probe that permits highly specific and sensitive detection of lipid droplets and hypochlorous acid via "off-on" and ratiometric readouts, respectively. Based on this format, the upregulated lipid accumulation and oxidative stress-the two hallmarks of atherosclerosis (AS)-were specifically measured in the atherosclerotic plaques, breaking through the barrier of precise tissue biopsy of AS and thus aiding effective CVD stewardship.

Eur J Neurol 2022; 29:2683-2689. [PMID: 35608963 DOI: 10.1111/ene.15418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 04/29/2022] [Accepted: 05/19/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND AND PURPOSE Intracranial atherosclerotic stenosis (ICAS) is a major cause of stroke in Asian countries. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, a hereditary enzyme defect prevalent in Asian countries, has been associated with atherosclerotic cardiovascular disease and worse poststroke outcomes. However, the impact of G6PD deficiency on ICAS remains unclear. We aimed to compare the risk of ICAS in stroke patients with and without G6PD deficiency in a Chinese cohort. METHODS We prospectively and consecutively recruited stroke patients from four centers in China. All patients received intracranial artery assessment by magnetic resonance/computed tomography angiography or digital subtraction angiography, as well as G6PD enzyme evaluation. The prevalence, burden, and characteristics of ICAS were compared between patients with and without G6PD deficiency using multivariate regression analysis. RESULTS Among 1593 patients, 116 (63.7%) of 182 patients with G6PD deficiency and 714 (50.6%) of 1411 patients with normal G6PD levels were identified as ICAS. Age, hypertension, diabetes, and G6PD deficiency were independent predictors of ICAS. Among patients with ICAS, G6PD-deficient individuals were more likely to have multiple (≥2 segments) intracranial stenosis (odds ratio [OR] = 1.87, 95% confidence interval [CI] = 1.25-2.81, p = 0.002). G6PD deficiency increased the risk of ICAS in patients who were male (OR = 1.82, 95% CI = 1.24-2.66, p = 0.002), aged ≥70 years (OR = 2.40, 95% CI = 1.33-4.31, p = 0.004), or hypertensive (OR = 1.88, 95% CI = 1.28-2.77, p = 0.001). CONCLUSIONS Stroke patients with G6PD deficiency have a higher prevalence and ICAS burden than those with normal G6PD, particularly those who are male, older, and hypertensive.

Lipidomics in Understanding Pathophysiology and Pharmacologic Effects in Inflammatory Diseases: Considerations for Drug Development. Metabolites 2022; 12:metabo12040333. [PMID: 35448520 PMCID: PMC9030008 DOI: 10.3390/metabo12040333] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 03/29/2022] [Accepted: 04/04/2022] [Indexed: 01/26/2023] Open
Abstract
The lipidome has a broad range of biological and signaling functions, including serving as a structural scaffold for membranes and initiating and resolving inflammation. To investigate the biological activity of phospholipids and their bioactive metabolites, precise analytical techniques are necessary to identify specific lipids and quantify their levels. Simultaneous quantification of a set of lipids can be achieved using high sensitivity mass spectrometry (MS) techniques, whose technological advancements have significantly improved over the last decade. This has unlocked the power of metabolomics/lipidomics allowing the dynamic characterization of metabolic systems. Lipidomics is a subset of metabolomics for multianalyte identification and quantification of endogenous lipids and their metabolites. Lipidomics-based technology has the potential to drive novel biomarker discovery and therapeutic development programs; however, appropriate standards have not been established for the field. Standardization would improve lipidomic analyses and accelerate the development of innovative therapies. This review aims to summarize considerations for lipidomic study designs including instrumentation, sample stabilization, data validation, and data analysis. In addition, this review highlights how lipidomics can be applied to biomarker discovery and drug mechanism dissection in various inflammatory diseases including cardiovascular disease, neurodegeneration, lung disease, and autoimmune disease.

[PMID: 35135065 PMCID: PMC8829474 DOI: 10.5853/jos.2021.02355] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 11/19/2021] [Indexed: 11/11/2022] Open
Abstract
Background and Purpose Oral anticoagulants are needed in stroke patients with atrial fibrillation (AF) for the prevention of recurrent stroke. However, the risk of major events or bleeding may be greater in stroke patients than in those without, because the presence of cerebral atherosclerosis or small vessel disease may increase these risks. This study aimed to investigate the outcomes of apixaban-treated stroke patients with AF and assess whether these factors are associated with the outcome.
Methods This was a sub-analysis of stroke patients with AF enrolled in a prospective, open-label, multicenter, post-marketing surveillance study in South Korea, who were treated with apixaban and underwent magnetic resonance imaging (MRI) (Clinical trial registration: NCT01885598).
Results A total of 651 patients (mean age, 72.5±8.7 years) received apixaban for a mean duration of 82.7±37.4 weeks. Fifty-three bleeding events occurred in 39 patients (6.0%), and 10 (1.5%) experienced major bleeding. Seventeen patients (2.6%) had major events (stroke, n=15, 2.3%; all ischemic), systemic embolism (n=1, 0.2%), and death (n=3, 0.5%). MRI data showed no significant association between white matter ischemic changes and microbleeds, and major events or bleeding. Patients with cerebral atherosclerotic lesions had a higher rate of major events than those without (4.6% [n=10/219] vs. 1.7% [n=7/409], P=0.0357), which partly explains the increased prevalence of major outcomes in this group versus patients without stroke (0.7%, P=0.0002).
Conclusions Apixaban is generally safe for patients with ischemic stroke. Increased primary outcomes in stroke patients may in part be attributed to the presence of cerebral atherosclerotic lesions, suggesting that further studies are needed to establish therapeutic strategies in this population.

Abstract
OBJECTIVE We present an update of the Spanish Society of Neurology's recommendations for prevention of both primary and secondary stroke in patients with dyslipidaemia. DEVELOPMENT We performed a systematic review to evaluate the main aspects of the management of dyslipidaemias in primary and secondary stroke prevention and establish a series of recommendations. CONCLUSIONS In primary prevention, the patient's vascular risk should be determined in order to define target values for low-density lipoprotein cholesterol. In secondary prevention after an atherothrombotic stroke, a target value <55mg/dL is recommended; in non-atherothombotic ischaemic strokes, given the unclear relationship with dyslipidaemia, target value should be established according to the vascular risk group of each patient. In both primary and secondary prevention, statins are the drugs of first choice, and ezetimibe and/or PCSK9 inhibitors may be added in patients not achieving the target value.

Abstract
BACKGROUND In ischemic stroke patients with active cancer, cryptogenic stroke has worse prognosis than stroke by conventional mechanisms. However, the individual effects of intracranial atherosclerosis (ICAS) or atrial fibrillation (AF) on the prognosis of these patients have not been studied. AIMS Therefore, we aimed to investigate the effects of ICAS and AF on the prognosis of ischemic stroke patients with active cancer. METHODS We included ischemic stroke patients with active cancer between 2010 and 2020. Early neurological deterioration (END) was defined as an increase of ≥ 1 in the motor NIHSS score, or ≥ 2 in the total NIHSS score within 72 hours of admission. Unfavorable outcomes were defined as a score of ≥ 3 on the 3-month modified Rankin Scale. RESULTS In total, 116 ischemic stroke patients with active cancer were evaluated. In multivariable analysis, ICAS was positively associated with END (adjusted odds ratio [aOR] = 4.56, 95% confidence interval [CI]: 1.52-13.70), and this association showed a quantitative relationship according to the degree of stenosis of ICAS (stenosis group: aOR = 4.24, 95% CI: 1.31-13.72; occlusion group, aOR = 5.74, 95% CI: 1.05-31.30). ICAS was also closely related to unfavorable outcomes (aOR = 6.33, 95% CI: 1.15-34.79). In contrast, AF showed no significant association with END or unfavorable outcomes. Our data showed that patients with ICAS had larger and more severe initial stroke lesions, and poorer prognosis than those without. CONCLUSIONS ICAS, but not AF, was closely associated with poor prognosis in ischemic stroke patients with active cancer.

Cerebral arteriosclerosis stenosis predicts poor short-term prognosis in non-valvular atrial fibrillation related cardioembolic stroke treated by reperfusion therapy. Clin Neurol Neurosurg 2021; 207:106738.

Abstract
BACKGROUND AND PURPOSE We aimed to investigate the association between cerebral arteriosclerosis stenosis (CAS) and the short-term prognosis of non-valvular atrial fibrillation (NVAF) related cardioembolic stroke treated by reperfusion therapy. METHODS The data of 195 consecutive NVAF related cardioembolic stroke patients were retrospectively collected. We defined poor functional outcome as a modified Rankin scale (mRS) score of > 2 at 90 days. RESULTS Patients with CAS were more likely to be older (75.5 ± 6.8 vs. 72.5 ± 9.2 years, p = 0.001), more current smokers (35.6% vs. 24.1%, p = 0.018), with hypertension (88.1% vs. 65.6%, p < 0.001), diabetes mellitus (50.0% vs. 20.0%, p = 0.020), dyslipidemia (33.9% vs. 23.6%, p = 0.029), previous history of stroke (30.5% vs. 19.5%, p = 0.012), and congestive heart failure (32.2% vs. 22.6%, p = 0.041). Patients with CAS had higher National Institutes of Health Stroke Scale (NIHSS) (18 [13, 22] vs. 15 [9, 19], p < 0.001), and 90-day mRS scores (5 [3, 6] vs. 3[2, 5], p < 0.001). Multivariate logistic regression analysis showed that CAS (odds ratio [OR] 3.184, 95% confidence interval [CI] 1.314-7.713, p = 0.01), NIHSS score on admission (OR 1.228 [per 1 point], 95% CI 1.146-1.316, p < 0.001), congestive heart failure (OR 2.850, 95% CI 1.108-7.331, p = 0.030), and current smokers (OR 2.841, 95% CI 1.102-7.326, p = 0.031) were independent predictors of a poor functional outcome at 90 days. CONCLUSION We should give the coexistence of CAS and NVAF related cardioembolic stroke proper attention. CAS was an independent factor for predicting the short-term prognosis of NVAF associated cardioembolic stroke patients treated by reperfusion therapy.

Intracranial arterial stenosis in Caucasian versus Chinese patients with TIA and minor stroke: two contemporaneous cohorts and a systematic review. J Neurol Neurosurg Psychiatry 2021; 92:jnnp-2020-325630. [PMID: 33785575 PMCID: PMC8142447 DOI: 10.1136/jnnp-2020-325630] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 12/21/2020] [Accepted: 01/04/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Intracranial arterial stenosis (ICAS) is an important cause of stroke worldwide. Separate reports in Caucasians and Asians with stroke/transient ischaemic attack (TIA) have suggested lower ICAS prevalence in Caucasians, but there has been no direct comparisons of the two ethnic groups with the same criteria to define ICAS. METHODS Acute minor stroke or TIA patients in two cohorts respectively recruiting patients in Oxford (2011-2018, predominantly Caucasians) and Hong Kong (2011-2015, predominantly Chinese) were compared. ICAS was defined as ≥50% stenosis/occlusion in any major intracranial artery in MR/CT angiography. Prevalence, distribution and risk factors of ICAS were compared between the two cohorts. We also systematically reviewed literature on ICAS prevalence in stroke/TIA patients in different populations. RESULTS Among 1287 patients from Oxford and 691 from Hong Kong (mean age 69 vs 66), ICAS prevalence was higher in Chinese than in Caucasians (43.0% vs 20.0%; OR 3.02; 95% CI 2.47 to 3.70; p<0.001), independent of age (age-adjusted OR 3.73; 95% CI 3.00 to 4.63; p<0.001) and vascular risk factors (multivariable-adjusted OR 3.21; 95% CI 2.56 to 4.02; p<0.001). This ethnic difference was greater (p interaction=0.005) at age <70 years (OR 5.33; 95% CI 3.79 to 7.50; p<0.001) than at ≥70 years (OR 2.81; 95% CI 2.11 to 3.74; p<0.001). ICAS prevalence increased with age and with vascular risk factors in both cohorts, with equivalent prevalence in Chinese aged <60 years and Caucasians aged ≥80, and in Chinese with no vascular risk factor and Caucasians with two vascular risk factors. ICAS locations also differed between Chinese and Caucasian patients. CONCLUSIONS Chinese are more susceptible to ICAS than Caucasians, with an earlier onset age and a higher prevalence, independent of vascular risk factors.

Infarct Recurrence in Intracranial Atherosclerosis: Results from the MyRIAD Study. J Stroke Cerebrovasc Dis 2020; 30:105504. [PMID: 33276302 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105504] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 10/05/2020] [Accepted: 11/21/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Intracranial atherosclerotic disease (ICAD) is a common cause of ischemic stroke with a high risk of clinical stroke recurrence. Multiple mechanisms may underlie cerebral ischemia in this condition. The study's objective is to discern the mechanisms of recurrent ischemia in ICAD through imaging biomarkers of impaired antegrade flow, poor distal perfusion, abnormal vasoreactivity, and artery-to-artery embolism. METHODS This prospective multicenter observational study enrolled patients with recent (≤21 days) ischemic stroke or transient ischemic attack (TIA) caused by ICAD with 50-99% stenosis treated medically. We obtained baseline quantitative MRA (QMRA), perfusion MRI (PWI), transcranial Doppler vasoreactivity (VMR), and emboli detection studies (EDS). The primary outcome was ischemic stroke in the territory of the stenotic artery within 1 year of follow-up; secondary outcomes were TIA at 1 year and new infarcts in the territory on MRI at 6-8 weeks. RESULTS Amongst 102 of 105 participants with clinical follow-up (mean 253±131 days), the primary outcome occurred in 8.8% (12.7/100 patient-years), while 5.9% (8.5/100 patient-years) had a TIA. A new infarct in the territory of the symptomatic artery was noted in 24.7% at 6-8 weeks. A low flow state on QMRA was noted in 25.5%, poor distal perfusion on PWI in 43.5%, impaired vasoreactivity on VMR in 67.5%, and microemboli on EDS in 39.0%. No significant association was identified between these imaging biomarkers and primary or secondary outcomes. CONCLUSIONS Despite intensive medical management in ICAD, there is a high risk of clinical cerebrovascular events at 1 year and an even higher risk of new imaging-evident infarcts in the subacute period after index stroke. Hemodynamic and plaque instability biomarkers did not identify a higher risk group. Further work is needed to identify mechanisms of ischemic stroke and infarct recurrence and their consequence on long-term physical and cognitive outcomes.

Risk of Recurrence of Symptomatic Intracranial Atherosclerosis in Posterior Circulation Seen to Be Higher Than That in Anterior Circulation in Long-Term Follow-Up. Front Neurol 2020; 11:574926. [PMID: 33240200 PMCID: PMC7677522 DOI: 10.3389/fneur.2020.574926] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Accepted: 10/16/2020] [Indexed: 11/13/2022] Open
Abstract
Background: Intracranial atherosclerotic stenosis (ICAS) is an important cause of ischemic stroke. In Asians, intracranial atherosclerotic disease leads to 33-50% of ischemic events. At present, treatment with medication vs. endovascular therapy (EVT) for symptomatic ICAS (sICAS) patients is still debatable. The clinical prognosis of patients who are not completely free of stroke symptoms despite regular medication and are not eligible for EVT for various reasons, is not yet investigated. Aim: To report the long-term recurrence rate of stroke in a cohort of symptomatic ICAS patients who intended to undergo EVT upon admission but could not for various reasons after digital subtraction angiography (DSA) evaluation. Method: This is a retrospective analysis of consecutive sICAS patients in a single center from January 1, 2016 to August 31, 2017 who underwent DSA assessment alone and were not eligible for further EVT. Demographic information, risk factors related to cerebrovascular disease, clinical comorbidities, medication, imaging data, and long-term outcomes were reported. Results: A total of 218 patients were included in the study; 42 (19.2%) patients had recurrence of stroke/transient ischemic attack (TIA) at the 1-year follow up. Patients were divided into two groups according to lesions in anterior circulation (n = 120) or posterior circulation (n = 98). There was a higher stroke/TIA recurrence rate in the posterior circulation than anterior circulation group (25.5 vs. 14.2%, p = 0.035). Given the advanced age, higher prevalence of coronary heart disease, larger stenosis length, and poorer collateral circulation, the posterior circulation group showed a higher risk of recurrent stroke/TIA and death than the anterior circulation group [HR = 3.092, 95% CI (1.335-7.164), p = 0.0084], after adjusting for all confounding factors in the COX regression model. Kaplan-Meier analysis showed that sICAS recurrence and mortality risk in the posterior circulation group was consistently higher than that in the anterior circulation group (log-rank-test, p = 0.033). Conclusions: Patients with posterior circulation sICAS have higher recurrence risk than those with anterior circulation managed with medication alone. Further, posterior circulation lesion is an independent risk factor for recurrence in sICAS patients.

Plaque characteristics of middle cerebral artery assessed using strategically acquired gradient echo (STAGE) and vessel wall MR contribute to misery downstream perfusion in patients with intracranial atherosclerosis. Eur Radiol 2020; 31:65-75. [PMID: 32740814 DOI: 10.1007/s00330-020-07055-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 04/21/2020] [Accepted: 06/30/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES To assess plaque vulnerability of the middle cerebral artery (MCA) using strategically acquired gradient echo (STAGE) versus high-resolution vessel wall MRI (hr-vwMRI), and explore the relationship between plaque characteristics and misery downstream perfusion. METHODS Ninety-one patients with single MCA atherosclerotic plaques underwent STAGE and hr-vwMRI were categorized into a group with misery perfusion and a group without based on the Alberta Stroke Program Early CT score (MTT-ASPECTS) with a threshold of 6. Plaque characteristics including inner lumen area (IWA), susceptibility, presence of hyperintensity within plaque (HIP), surface irregularity, stenosis degree, remodeling index, lipid ratio, and enhancement grade were compared between the two groups. The vulnerability of each plaque was retrospectively assessed on both STAGE and hr-vwMRI according to the combination of plaque features. Logistic regression analysis and ROC curve were performed to evaluate the effect of plaque characteristics on the presence of misery perfusion. RESULTS Taking hr-vwMRI as the reference, STAGE showed good efficiency in detecting vulnerable plaques. Patients with misery perfusion had less IWA, higher stenosis degree, more irregular surface and HIP, higher enhancement grade, and susceptibility (p < 0.01 for all). Higher susceptibility and stenosis degree were independent predictors for the occurrence of misery perfusion (p = 0.025, p = 0.048). The AUC was 0.900 for the combination of the two variables. CONCLUSION STAGE shows good efficiency to assess MCA plaque vulnerability versus hr-vwMRI. Plaque susceptibility evaluated using STAGE provides incremental value to predict misery perfusion combined with hr-vwMRI plaque features. KEY POINTS • STAGE has good efficiency in evaluating MCA plaque vulnerability versus hr-vwMRI. • Higher plaque susceptibility assessed using STAGE and higher grade luminal stenosis based on hr-vwMRI attribute to misery downstream perfusion. • STAGE provides incremental value on the understanding of plaque vulnerability in addition to conventional hr-vwMRI.

Abstract
Cardiovascular and cerebrovascular diseases, which mainly consist of atherosclerosis (AS), are major causes of death. A great deal of research has been carried out to clarify the molecular mechanisms of AS. However, the etiology of AS remains poorly understood. To screen the potential genes of AS occurrence and development, GSE43292 and GSE57691 were obtained from the Gene Expression Omnibus (GEO) database in this study for bioinformatic analysis. First, GEO2R was used to identify differentially expressed genes (DEGs) and the functional annotation of DEGs was performed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The Search Tool for the Retrieval of Interacting Genes (STRING) tool was used to construct the protein-protein interaction network and the most important modules and core genes were mined. The results show that a total of 211 DEGs are identified. The functional changes of DEGs are mainly associated with the cellular process, catalytic activity, and protein binding. Eighteen genes were identified as core genes. Bioinformatic analysis showed that the core genes are mainly enriched in numerous processes related to actin. In conclusion, the DEGs and hub genes identified in this study may help us understand the potential etiology of the occurrence and development of AS.

Abstract
OBJECTIVES Patients with coronary artery disease (CAD) concomitant with extracranial and intracranial atherosclerotic disease (EICAD) may have an increased risk of stroke and myocardial ischemic events. This study aimed to evaluate the concomitant atherosclerotic lesions in extra- and intracranial arterial beds in patients with CAD. METHODS A total of 1274 patients who underwent coronary angiography due to ischemic heart disease were included. All patients underwent ultrasound screening of the extra- and intracranial arteries before coronary angiography, and the degrees of extracranial carotid artery disease (ECAD) and intracranial cerebral artery disease (ICAD) were recorded. RESULTS A total of 1062 cases of CAD were confirmed. The prevalence of ECAD, ICAD, and EICAD (ECAD combined with ICAD) in patients with CAD was 15.6%, 11.2% and 11.9%, respectively. For patients with 3-vessel disease, the prevalence was 20.5%, 13.8% and 18.1%, and for patients with severe coronary artery stenosis, the prevalence was 15.8%, 12.1% and 13.2%, respectively. The presence and extent of ECAD and ICAD were positively correlated with the number of lesion vessels and degree of CAD. The posterior circulation arteries were more prone to lesions in patients with ECAD, while the anterior circulation arteries were more vulnerable to lesions in patients with ICAD. CONCLUSIONS The prevalence of ECAD, ICAD and EICAD is high in patients with CAD, and the presence of these conditions is positively correlated with the extent and degree of CAD. Evaluations of ECAD and ICAD should be highly recommended for CAD patients to reduce the future risk of cardiovascular diseases.

Abstract
The prevalence of intracranial arterial stenosis (IAS) as well as antinuclear antibody (ANA) positivity was found to be higher in Asians than that in the Western population. To investigate the relation of ANAs with IAS in patients with acute ischemic cerebrovascular disease, we enrolled 2492 patients with acute ischemic stroke or transient ischemic attack into the study. All the patients were categorized into 3 groups according to the IAS burden. Multinomial logistic regression analyses were used in statistical analysis. The positive rate of ANAs in the IAS ≥ 2 group was higher than that in the single IAS group and the no IAS group (p<0.001). The adjusted odds ratio (OR) for IAS ≥ 2 in ANAs-positive patients was 3.737 (95%CI=2.676-5.220, p<0.001) compared with the ANAs-negative patients. ANAs were associated with multiple IAS rather than single IAS in both male and female subgroups. Besides, ANAs were significantly associated with single and multiple IAS in individuals ≤ 60 years. However, ANAs were only associated with two or more IAS in two age groups (between 61 to 75 years and >75 years old). In summary, ANAs are associated with IAS in patients with acute ischemic cerebrovascular disease.

Abstract
ObjectiveTo evaluate the interaction effect of lipoprotein-associated phospholipase A2 (Lp-PLA2) activity on the efficacy and safety of dual/single antiplatelet therapy in patients with and without intracranial arterial stenosis (ICAS) by the Clopidogrel in High-Risk Patients with Acute Non-disabling Cerebrovascular Events trial.MethodsPatients with both MRI analysis and Lp-PLA2 testing results were included in the current subanalysis. The interaction of Lp-PLA2 activity with the effects of dual and single antiplatelet therapy were analyzed through Cox proportional hazards regressions model.ResultsAmong the 797 patients, the mean age was 63.1 ± 10.8 years, 518 (65%) were men, 356 (44.7%) had ICAS, and 441 (55.3%) did not. There were significantly more patients with elevated Lp-PLA2 activity in the ICAS group than in the non-ICAS group (43.8% vs 35.4%, p = 0.02). There was significant interaction between Lp-PLA2 activity levels and the 2 antiplatelet therapies for prevention of stroke recurrences and combined vascular events even after adjustment for confounding factors exclusively for patients with ICAS (p = 0.017, 0.017, respectively), but not for those without (p = 0.332, 0.674, respectively). Compared with aspirin alone, dual antiplatelet therapy significantly reduced the risk of stroke recurrences and combined vascular events (adjusted hazard ratio 0.33 [0.12–0.89], p = 0.028; 0.33 [0.12–0.89], p = 0.028, respectively) for patients with ICAS and nonelevated Lp-PLA2 activity.ConclusionsPresence of both ICAS and nonelevated Lp-PLA2 activity may predict better response to dual antiplatelet therapy in prevention of recurrent strokes and combined vascular events for patients with minor stroke or high-risk TIA.Clinicaltrials.gov identifierNCT00979589.

Abstract
Background: Adipokines have been proven to be associated with atherosclerotic diseases such as ischemic stroke and coronary heart disease. The role of novel adipokines in the development of symptomatic intracranial atherosclerotic stenosis (sICAS) and extracranial atherosclerotic stenosis (sECAS) has not yet been investigated. This study aimed to evaluate the plasma levels of novel adipokines in patients with sICAS and sECAS and their associations with the prognosis of sICAS groups. Methods: A total of 134 patients with acute ischemic stroke attribute to large-artery atherosclerosis (LAA) and 66 age- and sex-matched controls without atherosclerotic stenosis (NCAS) were included in this study. The LAA group was further sub-classified as sICAS (n = 102) and sECAS (n = 32) according to the location of atherosclerosis. Demographics, clinical parameters, angiographical features and plasma levels of novel adipokines (apelin, visfatin, omentin, RBP-4) were assayed and compared among groups. Results: LAA patients had significantly lower levels of omentin [39.92 (30.74–52.61) ng/ml vs. 54.42 (34.73–79.91) ng/ml, P < 0.001] and visfatin [11.32 (7.62–16.44) ng/ml vs. 13.01 (9.46–27.54) ng/ml, P < 0.001] than those in the NCAS group. Multiple logistic regression analysis identified that the lowest tertile of omentin was independently associated with LAA (OR, 3.423; 95% CI, 1.267–9.244, when referenced to the third tertile). Levels of omentin, visfatin and RBP-4 showed no significant difference between sICAS and sECAS groups. However, median concentrations of apelin were lower in sECAS [84.94 (46.88–130.41) ng/mL) than in sICAS [118.64 (93.22–145.08) ng/mL, P = 0.002] and NCAS [114.38 (80.56–162.93) ng/mL, P = 0.004]. Logistic regression analysis showed that the lowermost tertile of apelin was independently associated with sECAS (OR, 5.121; 95% CI, 1.597–16.426) when adjusted for risk factors. As for sICAS patients, spearman coefficient analysis showed no significant correlation between these four adipokines and the severity of sICAS or the number of vessels with intracranial stenoses. Patients with severe stroke had lower levels of apelin (P = 0.005), while the other three adipokines showed no such difference. During follow up, no difference was found between these four novel adipokines and short- and long-term outcome of sICAS. Conclusions: Lower levels of omentin are independent biomarkers of LAA while low apelin plasma levels seem to be risk factors of sECAS.

Abstract
Aims: Coronary artery stenosis (CAS) ≥ 50% frequently coexists in patients with acute ischemic cerebrovascular disease (AICVD), which portends unfavorable outcomes. We sought to examine whether patients with AICVD with CAS had more severe and more diffused cervicocephalic atherosclerosis (CA). Methods: Patients with AICVD were consecutively enrolled and underwent simultaneous computed tomography angiography (CTA) of the coronary and cervicocephalic arteries. A total of 140 patients were divided into “AICVD + CAS” and “AICVD only” groups according to whether CTA showed stenosis of ≥ 50% in at least one coronary arterial segment. The relationship of the presence of CAS with the severity and extent of CA were examined. Results: The CA severity characteristics, including the presence of stenosis ≥ 50% and the grade of the most severe stenotic segment, were not significantly different between the two groups. Regarding the extent of CA, the presence of stenosis ≥ 50% in both sides (adjusted odds ratio [OR]: 4.29, 95% confidence interval [CI]: 1.67–10.98), both extracranial and intracranial (adjusted OR: 5.26, 95% CI: 2.24–12.35), both anterior and posterior circulation (adjusted OR: 5.29, 95% CI: 2.22–12.64), and the number of stenotic segments ≥ 50% in cervicocephalic arteries (adjusted OR: 1.58, 95% CI: 1.28–1.96) were associated with CAS in patients with AICVD, independently of clinical demographics and CA severity characteristics. Conclusion: CA was similarly severe in patients with AICVD with and without CAS, but those with CAS had significantly more diffused CA. The extent of CA and CAS were mutual indicators in patients with AICVD, irrespective of CA severity.

Abstract
BACKGROUND AND AIMS Symptomatic intracranial atherosclerosis (ICAS) is associated with a high risk of stroke recurrence and occurrence of other vascular events. However, ICAS has been poorly studied from its asymptomatic stage. The objective of our study was to determine if subclinical intracranial atherosclerosis is associated with long-term incident vascular events in Caucasians. METHODS The Barcelona-Asymptomatic Intracranial Atherosclerosis (AsIA) Study is a population-based study that enrolled 933 subjects with a moderate-high vascular risk and without history of stroke or coronary disease, and determined the prevalence of asymptomatic ICAS and associated risk factors. At baseline visit, carotid atherosclerosis and ICAS were screened by color-coded duplex ultrasound, and moderate-severe stenosis was confirmed by magnetic resonance angiography. At baseline, 8.9% of subjects had asymptomatic ICAS, of whom 3.3% were moderate-severe. In the longitudinal phase, subjects were prospectively followed-up to assess the incidence of a combined primary endpoint of vascular events (stroke, acute coronary syndrome and/or vascular death). RESULTS After 7.17 years of follow-up, there were 51 incident cerebrovascular events (16 transient ischemic attacks, 27 ischemic, 8 hemorrhagic strokes), 63 incident coronary events and 23 vascular deaths. After multivariate Cox regression analyses adjusted by age, sex, vascular risk and presence of carotid plaques, ICAS was an independent predictor for overall vascular events (HR 1.83 [1.10-3.03], p = 0.020), and moderate-severe intracranial stenosis was also an independent predictor for cerebrovascular events (HR 2.66 [1.02-6.94], p = 0.046). CONCLUSIONS Asymptomatic ICAS is independently associated with the incidence of future vascular events in our population. These findings might have implications for the development of primary prevention strategies.

Abstract
Atherosclerosis is a major cause of ischemic stroke that can be effectively prevented with appropriate lifestyle modifications and control of cardiovascular risk factors. Medical advances in recent years along with aggressive cardiovascular risk factor modifications have resulted in decreased recurrence rates of atherosclerotic stroke. Non-statin lipid-lowering molecules have recently shown clinical benefit and are recommended for very high-risk patients to reduce their risk of stroke. Aggressive hypertension treatment is crucial to reduce atherosclerotic stroke risk. Advances in antithrombotic treatments include combinations of antiplatelets and new antiplatelet agents in the acute phase post-stroke, which carries a high risk of recurrence. Intensive medical treatment has also limited the indications for carotid interventions, especially for asymptomatic disease. Intracranial atherosclerotic disease may provoke stroke through various mechanisms; it is increasingly recognized as a cause of ischemic stroke with advanced imaging and is best managed with lifestyle modifications and medical therapy. The diagnostic search for the vulnerable culprit atherosclerotic plaque is an area of intense research, from the level of the intracranial arteries to that of the aortic arch. Ultrasonography and novel magnetic resonance imaging techniques (high-resolution vessel-wall imaging) may assist in the identification of vulnerable atherosclerotic plaques as the underlying cause in cryptogenic or misdiagnosed non-atherosclerotic ischemic stroke. Vertebrobasilar atherosclerotic disease is less common than carotid artery disease; thus, high-quality data on effective prevention strategies are scarcer. However, aggressive medical treatment is also the gold standard to reduce cerebrovascular disease located in posterior circulation.
