Background/Objectives: Cerebrovascular events (CVEs) are a leading cause of intensive care unit (ICU) admissions from the emergency department, often associated with high morbidity and mortality rates. Identifying reliable, non-invasive predictors of mortality in these patients is critical for improving prognostic accuracy and guiding therapeutic strategies. This retrospective cohort study evaluates the predictive value of the optic nerve sheath diameter (ONSD), measured using magnetic resonance imaging (MRI), in determining mortality among ICU patients with CVEs. Methods: This single-center, retrospective observational study included 102 patients diagnosed with CVEs and admitted to the ICU at Gaziantep City Hospital between October 2023 and March 2024. This study adhered to the Declaration of Helsinki. Ethics approval was obtained from Gaziantep Islam Science and Technology University (Decision No. 394.36.08), and the requirement for informed consent was waived due to the retrospective design. The sample size was determined using G-Power 3.1.9.4. Results: A statistically significant positive correlation was observed between the ONSD and mortality (p = 0.002). Patients with higher ONSD values demonstrated an increased mortality risk, underscoring the potential prognostic value of ONSD measurements in this population. Conclusions: MRI-based ONSD measurement offers a non-invasive method for predicting mortality in ICU patients with CVEs. Its integration into routine diagnostic protocols could enhance clinical decision-making and patient outcomes. Further multicenter studies are warranted to validate these findings and standardize ONSD measurement techniques. [ABSTRACT FROM AUTHOR]

Background and Objectives: This study aimed to investigate the clinical significance of sarcopenia, defined by the cross-sectional area of the masseter muscle (CSA-M), as an early marker for sarcopenia diagnosis and its association with mortality in patients with cerebrovascular events (CVE). Materials and Methods: In this retrospective cohort study, 120 patients aged 65 years or older with CVE admitted to Bilkent City Hospital between September 2020 and September 2023 were included. Patients with malignancy, prior CVE, or incomplete data were excluded. Parameters such as CSA-M measured via brain CT, Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores, Nutritional Risk Score (NRS), duration of ICU and hospital stays, and 28-day mortality were evaluated. The CSA-M thresholds for sarcopenia were defined as <400 mm2 for men and <300 mm2 for women. Results: Sarcopenia prevalence was significantly associated with prolonged ICU (27.0 ± 33.1 days vs. 16.5 ± 22.4 days, p = 0.042) and hospital stays (34.8 ± 38.4 days vs. 21.3 ± 22.3 days, p = 0.017). Right and left CSA-M values were significantly lower in sarcopenic patients (p < 0.001). ROC analysis revealed CSA-M cut-off values of <300 mm2 (AUC = 0.82) for men and <295 mm2 (AUC = 0.83) for women as strong predictors of sarcopenia. Multivariate regression analysis showed a significant association between CSA-M and 28-day mortality (p < 0.05). Sarcopenia also correlated with lower albumin levels, a higher prevalence of ischemic stroke, and increased mechanical ventilation needs. Conclusions: CSA-M measured via brain CT is a reliable marker for sarcopenia and a predictor of clinical outcomes in CVE patients. Early identification and management of sarcopenia could improve patient prognosis. Further research is warranted to explore its potential in broader clinical contexts. [ABSTRACT FROM AUTHOR]

Background/Aim: Transient ischaemic attack (TIA) is characterised by a temporary neurological dysfunction resulting from focal ischaemia in the brain, spinal cord or retina without acute infarction. These episodes typically last less than 24 hours and are significant predictors of subsequent ischaemic strokes. Hypertension is a major risk factor for cerebrovascular events, and primary aldosteronism (PA) is recognised as a common cause of secondary hypertension. This case report presents a male patient with secondary hypertension due to Conn Syndrome, a form of PA, who experienced a TIA manifesting as left leg weakness, underscoring the heightened stroke risk associated with secondary hypertension. Case Report: A 78-year-old male with secondary hypertension caused by Conn Syndrome presented with an episode of left leg weakness that resolved within 24 hours. After ruling out other potential causes such as metabolic disturbances, infections, and structural brain lesions, he was diagnosed with TIA and treated with dual antiplatelet therapy. A carotid ultrasound revealed significant stenosis, leading to a referral for carotid endarterectomy. Long-term management included clopidogrel monotherapy and optimising hypertension control. Conclusion: This case highlights the increased stroke risk in patients with Conn Syndrome-related hypertension, emphasising the importance of early recognition and optimising hypertension management in patients with secondary hypertension to prevent future cerebrovascular events.

Background/Objectives: Cerebrovascular events, such as strokes, are often preceded by the rupture of atherosclerotic plaques in the carotid arteries. This work introduces a novel approach to predict the occurrence of such events by integrating computational fluid dynamics (CFD), structural analysis, and machine learning (ML) techniques. The objective is to develop a predictive model that combines both imaging and non-imaging data to assess the risk of carotid atherosclerosis and subsequent cerebrovascular events, ultimately improving clinical decision-making. Methods: A multidisciplinary approach was employed, utilizing 3D reconstruction techniques and blood-flow simulations to extract key plaque characteristics. These were combined with patient-specific clinical data for risk evaluation. The study involved 134 asymptomatic individuals diagnosed with carotid artery disease. Data imbalance was addressed using two distinct approaches, with the optimal method chosen for training a Gradient Boosting Tree (GBT) classifier. The model's performance was evaluated in terms of accuracy, sensitivity, specificity, and ROC AUC. Results: The best-performing GBT model achieved a balanced accuracy of 88%, with a ROC AUC of 0.92, a sensitivity of 0.88, and a specificity of 0.91. This demonstrates the model's high predictive power in identifying patients at risk for cerebrovascular events. Conclusions: The proposed method effectively combines CFD, structural analysis, and ML to predict cerebrovascular event risk in patients with carotid artery disease. By providing clinicians with a tool for better risk assessment, this approach has the potential to significantly enhance clinical decision-making and patient outcomes. [ABSTRACT FROM AUTHOR]

Abstract Background and purpose Cerebrovascular events during thrombolysis in cardiac arrest (CA) caused by pulmonary embolism (PE) is a life-threatening condition. However, the balance between cerebrovascular events and thrombolytic therapy in PE-induced CA remains a great challenge. Methods In this study, we reported three unique cases regarding main concerns surrounding cerebrovascular events in thrombolytic therapy in PE-induced CA. Results The patient in the case 1 treated with thrombolysis during CPR and finally discharged neurologically intact. The patient in the case 2 received delayed thrombolysis and died eventually. The patient in the case 3 was contraindicated to thrombolysis due to the complication of subarachioid hemorrahage and died within days. Conclusions Our case series highlights three proposed approaches to consider before administering thrombolysis as a treatment option in PE-induced CA patients: (1) prolonging the resuscitation, (2) administering thrombolysis promptly, and (3) ruling out cerebrovascular events.

Objective. To assess the progression of carotid artery (CA) stenoses, the relationship to cerebrovascular events and lipid metabolism disorders in patients in the long-term period of coronary artery bypass surgery (CABG).Materials and methods. The prospective study included 152 patients, males, median age 57 years, of whom 37% had identified < 50% СA stenosis. Neuropsychological screening, duplex scanning of brachiocephalic arteries with colored Doppler blood flow mapping and lipid metabolism parameters evaluation were performed in all patients before and at 5-7 years after surgery. Statistical analysis was performed using the Statistica 10 program (StatSoft, Inc., USA).Results. It was found that the number of patients with CA stenosis increased to 57%, the incidence of acute ischemic stroke was 5% cases, dementia – 2.5% at 5-7 years after CABG. Also, in the group of CA stenoses, the number of cases of mild cognitive impairment increased from 18% to 23%. Only a small proportion of patients reached the target lipid concentrations, and none of patients with CA stenoses reached the target level of LDL. One-third of all patients examined at 5-7 years after CABG refused to take statins.Conclusion. In the long-term postoperative period of CABG (after 5-7 years) there was an increase in the number of patients with CA stenoses, some patients had ischemic strokes and dementia. At the same time, only a small proportion of patients with lipid was able to reach the optimal values recommended for CABG patients, and patients with CA stenoses were unable to reach the target cholesterol LDL concentrations.

Objectives: We clarified the characteristics and risk factors of CVEs in young SLE patients. Method: We retrospectively reviewed the medical records of patients younger than 50 years of age diagnosed with SLE and first CVEs from 1995 to 2020 in a tertiary medical center in Taiwan. We collected data on the patient characteristics before the CVE and reviewed the laboratory data obtained during the period. At a ratio of 1:3, cases and controls were matched with sex, SLE diagnosis age, diagnosis year, and SLE duration. Results: We enrolled 43 CVE SLE patients and matched 129 non-CVE SLE controls. The median age at the time of the CVE was 39 years. Around 70% of young-aged CVE involved the cerebral lobes of frontal (∼30%), parietal (∼20%), occipital (∼10%), and temporal (∼10%). The peak incidence period for hemorrhagic CVE was within 1st year of SLE diagnosis (37%); in contrast, during the 2nd to 5th year of SLE diagnosis (25%) for ischemia CVEs. Hyperlipidemia (odds ratio [OR] = 19.36, p = 0.002), anti-phospholipid syndrome (APS) (OR = 41.9, p = 0.0068), a lower hemoglobin level (OR = 0.66, p = 0.0192), and a higher SLE Disease Activity Index (SLEDAI-2k) score (OR = 1.22, p = 0.0019) were independent risk factors for CVEs in young SLE patients. Conclusion: Hyperlipidemia, APS, low Hb level, and high SLEDAI-2k significantly increase the risk of young-aged SLE patients developing CVE.

Objectives: While the link between carotid plaque composition and cerebrovascular vascular (CVE) events is recognized, the role of calcium configuration remains unclear. This study aimed to develop and validate a CT angiography (CTA)–based machine learning (ML) model that uses carotid plaques 6-type calcium grading, and clinical parameters to identify CVE patients with bilateral plaques. Material and methods: We conducted a multicenter, retrospective diagnostic study (March 2013–May 2020) approved by the institutional review board. We included adults (18 +) with bilateral carotid artery plaques, symptomatic patients having recently experienced a carotid territory ischemic event, and asymptomatic patients either after 3 months from symptom onset or with no such event. Four ML models (clinical factors, calcium configurations, and both with and without plaque grading [ML-All-G and ML-All-NG]) and logistic regression on all variables identified symptomatic patients. Internal validation assessed discrimination and calibration. External validation was also performed, and identified important variables and causes of misclassifications. Results: We included 790 patients (median age 72, IQR [61–80], 42% male, 64% symptomatic) for training and internal validation, and 159 patients (age 68 [63–76], 36% male, 39% symptomatic) for external testing. The ML-All-G model achieved an area-under-ROC curve of 0.71 (95% CI 0.58–0.78; p <.001) and sensitivity 80% (79–81). Performance was comparable on external testing. Calcified plaque, especially the positive rim sign on the right artery in older and hyperlipidemic patients, had a major impact on identifying symptomatic patients. Conclusion: The developed model can identify symptomatic patients using plaques calcium configuration data and clinical information with reasonable diagnostic accuracy. Clinical relevance: The analysis of the type of calcium configuration in carotid plaques into 6 classes, combined with clinical variables, allows for an effective identification of symptomatic patients. Key Points: • While the association between carotid plaques composition and cerebrovascular events is recognized, the role of calcium configuration remains unclear. • Machine learning of 6-type plaque grading can identify symptomatic patients. Calcified plaques on the right artery, advanced age, and hyperlipidemia were the most important predictors. • Fast acquisition of CTA enables rapid grading of plaques upon the patient's arrival at the hospital, which streamlines the diagnosis of symptoms using ML.

Abstract Background Few evidence-based prediction models have been developed for predicting major adverse cardiovascular and cerebrovascular events (MACCE) in patients aged 65 years or older undergoing noncardiac surgery. In this study, we aimed to analyze the risk factors for perioperative MACCE in patients aged 65 years or older undergoing noncardiac surgery and construct a prediction model. Methods In this nested case–control study, a total of 342 Chinese patients who were aged ≥ 65 years and underwent medium- or high-risk noncardiac surgery in our hospital were included. There were 84 cases with MACCE (the MACCE group) and 258 without MACCE (the control group). Univariable logistic regression analysis was performed to identify the risk factors for MACCE. Least absolute shrinkage and selection operator (LASSO) regression was used to screen the variables. Nomogram was constructed using the selected variables. Machine learning methods, including Decision Tree, XGBoost, Support Vector Machine, K-nearest Neighbor, and Neural network, was used to establish, validate, and compare the performance of different prediction models. Results A prediction model based on nine variables, including age ≥ 85 years, history of ischemic chest pain, symptoms of decompensated heart failure, high-risk surgery, intraoperative minimum systolic blood pressure, postoperative systolic blood pressure, Cr levels over 2.0 mg/dL, left ventricular ejection fraction, and perioperative blood transfusion, was constructed. This LASSO logistic regression model showed good discriminatory ability to predict MACCE (area under the curve = 0.89; 95% confidence interval, 0.818 – 0.963) and fit to the test set (Hosmer–Lemeshow, χ2 = 7.4053, P = 0.4936). The decision curve analysis showed a positive net benefit of the new model. Compared with logistic regression model, the XGBoost model showed better prediction ability (area under the curve = 0.903). A preoperative prediction model based on five variables, including age ≥ 85 years, symptoms of decompensated heart failure, ischemic chest pain, high-risk type of surgery and Cr levels over 2.0 mg/dL was also constructed. This model showed good discriminatory ability to predict MACCE before surgery (area under the curve = 0.720 [95% CI, 0.591–0.848]. Both models compared with the modified RCRI score had improvement in reclassification. Conclusion By analyzing Chinese patients aged ≥ 65 years undergoing medium- or high-risk noncardiac surgery, the risk factors for perioperative MACCE were identified. Then, simple prediction models were constructed and validated, which showed good prediction performance and may be used as a decision-making assistant tool for clinicians. These findings provide a basis for preventing and improving the perioperative management of MACCE.

Purpose : Radiotherapy (RT) is a recognized risk factor for cerebrovascular (CV) disease in children and in adults with head and neck cancer. We aimed to investigate whether cerebral RT increases the risk of CV disease in adults with primary brain tumors (PBT). Methods: We retrospectively identified adults with a supratentorial PBT diagnosed between 1975 and 2006 and with at least 10 years follow-up after treatment. We analyzed demographic, clinical, and radiological features with special attention to CV events. We also described CV events, vascular risk factors, and intracranial artery modifications in a cross-sectional study of irradiated patients alive at the time of the study. Results: A total of 116 patients, treated with RT (exposed group), and 85 non-irradiated patients (unexposed group) were enrolled. Stroke was more frequent in irradiated PBT patients than in the unexposed group (42/116 (36%) vs 7/85 (8%); p < 0.001), with higher prevalence of both ischemic (27/116 (23%) vs 6/85 (7%); p = 0.004) and hemorrhagic (12/116 (10%) vs 1/85 (1%); p = 0.02) stroke. In the irradiated group, patients with tumors near the Willis Polygon were more likely to experience stroke (p < 0.016). Fourty-four alive irradiated patients were included in the cross-sectional study. In this subgroup, intracranial arterial stenosis was more prevalent (11/45, 24%) compared to general population (9%). Conclusions: Stroke prevalence is increased in long-surviving PBT patients treated with cranial RT. Implications for cancer survivors: CV events are frequent in long survivors of PBT treated with cerebral RT. We propose a check list to guide management of late CV complications in adults treated with RT for PBT. [ABSTRACT FROM AUTHOR]

Patients receiving transcatheter aortic valve implantation (TAVI) are elderly with multiple comorbidities and at increased risk of perioperative cerebrovascular events. Retinal vasculature represents a surrogate of central nervous system circulation and is noninvasively achievable by retinal imaging. The aim of this study was to evaluate the applicability of retinal angiography of microvascular complications and association to cerebral ischemic events during TAVI. One hundred patients (male 54%, age: median 82 years, range 64–95 years) undergoing TAVI were recruited for this study. Imaging of retinal vasculature was evaluated with a handheld fundus camera before, during and 1 month after. Cerebrovascular events were determined as a part of contemporary clinical evaluation with cerebral CT and CTA imaging when symptoms occurred. Altogether 66/100 patients (66%) were included in the analysis. In-hospital ischemic event (transient ischemic attack, cerebral infarction) was observed in 1/66 patient (1.5%). Retinal vascular abnormalities occurred in 8/66 patients (12.1%); 4/66 patients (6.1%) were detected with a cholesterol plaque in the retinal artery, 2/66 (3%) a capillary leakage, 1/66 (1.5%) and optic disk hemorrhage and 1/66 (1.5%) a macular bleeding. No significant association between retinal vasculature abnormalities and cerebrovascular events was detected mainly due to the low event rate. Perioperative evaluation of cerebrovascular ischemia with noninvasive imaging of retinal vasculature is possible in most patients undergoing TAVI. More data is needed to evaluate the association of cerebrovascular events and retinal microvascular abnormalities during the procedure. [ABSTRACT FROM AUTHOR]

Silent cerebral infarction (SCI) is a neuronal injury without a clinically apparent stroke or transient ischaemic attack. Left atrial cardiomyopathy is closely associated with SCI. P wave changes in the electrocardiogram (ECG) provide significant information about the development of atrial cardiomyopathy. This study evaluated the role of P wave parameters and indices and a novel ECG parameter in predicting SCI, future cerebrovascular events, and atrial fibrillation/flutter. A total of 272 patients were retrospectively screened and divided into two groups according to SCI. Cerebrovascular events and atrial fibrillation/flutter were defined as the study's outcomes. P wave parameters, indices, and a novel ECG parameter called the P wave ratio (PWR) were calculated from ECGs, and the relationship between SCI and outcomes was investigated. The maximum P wave duration (PWD), P wave dispersion (PWdisp), PWD measured from the D2 lead (PWDD2), P wave peak time measured from the D2 lead (PWPTD2), PWPT measured from the V1 lead (PWPTV1), and P wave terminal force (PWTFV1) were significantly longer in the SCI group. Both partial and advanced inter atrial block (IAB) were significantly high in the SCI group. The novel parameter P wave ratio (PWR) was significantly longer in the SCI group (0.55 ± 0.08 vs. 0.46 ± 0.09; p < 0.001). In multivariate regression analysis, PWdisp (OR: 1.101, p < 0.001), PWPTD2 (OR: 1.095, p = 0.017), and PWR (OR: 1.231, p < 0.001) were found to be independent predictors of SCI. Cox regression analysis revealed that the PWR (HR 1.077; 95% CI 1.029–1.128; p = 0.001) was associated with cerebrovascular events and atrial fibrillation/flutter. In our study, we observed that PWR could be a valuable parameter for predicting SCI and future cerebrovascular events. [ABSTRACT FROM AUTHOR]

The novel Coronavirus disease (COVID-19) is associated with an increased risk of cerebrovascular events. About 1,228 cases of severe COVID-19 were hospitalized in the West Kazakhstan Medical University Hospital, in Aktobe, Kazakhstan, 1.22% (N=15) of whom were clinically diagnosed with acute cerebrovascular events and were included in the current study. COVID-19 was diagnosed using a nasopharyngeal polymerase chain reaction (PCR) test, blood count, inflammatory markers, and chest computerized tomography. The diagnosis of acute cerebrovascular events was based on the clinical manifestation. The participants' data were reviewed to detect the prevalence of acute cerebrovascular events and the inflammatory markers associated with COVID-19 infection. The mean age of the participants was 66.9 years (±11.07), 53% (N=8) of them were male, while 47% (N=7) were female. Moreover, 13% (N=2) presented a history of cerebrovascular events, 87% (N=13) of the participants had hypertension, 47% (N=7) had coronary heart disease, 33% (N=5) had diabetes mellitus (DM), 13% (N=2) had cardiac arrhythmia, and 13% (N=2) had chronic obstructive pulmonary disease (COPD). The C-reactive protein was high in 100% (N=15) of participants, D-dimer in 87% (N=13) of them, and both the ferritin and interleukin-6 were high in 60% (N=9) of the participants. SARS-CoV-2 causes a systemic inflammatory response, and the presence of comorbidities increases the risk of acute cerebrovascular events in COVID-19-infected individuals. The elevated inflammatory markers in severely COVID-19-infected individuals support the inflammatory "cytokine storm" response theory. [ABSTRACT FROM AUTHOR]

Aortic valve stenosis (AS) is a common heart valve disease in the elderly population, and its pathogenesis remains an interesting area of research. The degeneration of the aortic valve leaflets gradually progresses to valve sclerosis. The advanced phase is marked by the presence of extracellular fibrosis and calcification. Turbulent, accelerated blood flow generated by the stenotic valve causes excessive damage to the aortic wall. Elevated shear stress due to AS leads to the degradation of high-molecular weight multimers of von Willebrand factor, which may involve bleeding in the mucosal tissues. Conversely, elevated shear stress has been associated with the release of thrombin and the activation of platelets, even in individuals with acquired von Willebrand syndrome. Moreover, turbulent blood flow in the aorta may activate the endothelium and promote platelet adhesion and activation on the aortic valve surface. Platelets release a wide range of mediators, including lysophosphatidic acid, which have pro-osteogenic effects in AS. All of these interactions result in blood coagulation, fibrinolysis, and the hemostatic process. This review summarizes the current knowledge on high shear stress-induced hemostatic disorders, the influence of AS on platelets and antiplatelet therapy. [ABSTRACT FROM AUTHOR]

Recently, weeks after the COVID-19 prevalence, there were reports of brain involvement and neurologic presentations in the COVID-19. We present five cases of COVID-19 and cerebrovascular events. A 34-year-old woman with IVH and ischemic stroke. A 60-year-old man with multiple small hemorrhagic foci and mild IVH in the occipital horn. A 63-year-old woman with large left parietooccipital intracerebral hemorrhage (ICH) and IVH. A 56-year-old man with left hemispheric and midbrain ICH, lateral ventricular IVH, and hydrocephalus. A 85-year-old woman with right parietal hemorrhagic infarct. The coagulation profile was normal in all of them. The chest CT scan showed the typical ground-glass appearance of COVID-19. Recently, there were reports of brain involvement and neurologic presentations in the COVID-19. These reports and the present study necessitate the aimed and designed studies with emphasis on neurologic presentations in COVID-19 patients to illustrate the exact effects of coronavirus-2 on the central nervous system.

BackgroundPrimary cardiac tumors are often benign and commonly present as cardiac myxomas (CMs) or papillary fibroelastomas (CPFEs). There is a paucity of prognostic indicators for tumor burden or potential for embolic cerebrovascular events (CVEs). This study was performed to address these gaps.MethodsMedical records at the University of Florida Health Shands Hospital between 1996 and 2021 were screened to identify patients with CMs or CPFEs. Clinical features, echocardiographic reports, and CVE outcomes were quantitatively assessed.ResultsA total of 55 patients were included in the study: 28 CM (50.9%) and 27 CPFE (49.1%) patients. Baseline patient characteristics were similar among patients. The neutrophil–lymphocyte ratio was correlated (p 3.0 at the follow-up were significantly associated with 5-year CVE recurrence. Left atrial enlargement and a neutrophil–lymphocyte ratio >3.0 at the follow-up remained significantly associated with 5-year CVE recurrence in multivariate analysis.ConclusionThe neutrophil–lymphocyte ratio may prognosticate tumor size and recurrence of neurologic events. An increased risk of CVE within 5 years of mass resection is almost exclusive to patients initially presenting with CVEs.

INTRODUCTION: This study aimed to assess the impact of coronary artery bypass grafting (CABG) on outcomes in elderly patients compared to younger patients. METHOD: An observational case-control study was conducted involving 535 patients, divided into two groups: older adults (=75 years) and younger adults (<75 years). All patients underwent CABG following a similar protocol. The primary endpoints focused on early post-procedure outcomes, including in-hospital mortality and the duration of ICU or hospital stay. Patients were followed up for six months, and secondary study endpoints included long-term mortality, left ventricular ejection fraction, re-hospitalization rates, and repeated revascularization. RESULTS: 535 patients who underwent CABG were enrolled in this study. The smoking habit was significantly higher among younger adults (38.2% vs. 12.5%, P=0.001). Hypertension was more prevalent among older adults than younger adults (75% vs. 60%, P=0.044). LDL cholesterol serum levels were higher among younger adult patients (94.9±32.5 vs. 80.9±32.9, P=0.028). In-hospital death was not significantly different between younger and older adults (2.8% vs. 5.0%, P=0.34). Mortality in the six-month follow-up was non-significantly higher in the elderly (2.1% vs. 8.1%, P=0.06). A significant proportion of patients in both groups (46.9% in younger patients vs. 40% in older ones, P=0.40) received dual antiplatelet therapy (DAPT) prior to CABG due to a recent myocardial infarction and receipt of a new stent, but without increased major bleeding in both groups. CONCLUSION: CABG should be considered a viable treatment option for elderly patients with acceptable operative risk in current clinical practice. [ABSTRACT FROM AUTHOR]

Abstract Background Cerebral atherosclerosis (AS) leads to high risk of cerebrovascular events. This study aims to evaluate the diagnostic performance of serum microRNA-130a-3p (miR-130a-3p) in cerebral AS patients, and construct a logistic risk model for 2-year cerebrovascular events on the basis of the prognostic potential of miR-130a-3p. Methods Serum samples were collected from 74 cerebral AS patients and 62 control individuals, and miR-130a-3p expression was investigated using reverse transcription quantitative PCR. Risk factors related with cerebral AS were assessed using a logistic regression analysis, and the receiver operating characteristic analysis was performed to evaluate the diagnostic value of miR-130a-3p. The relationship between miR-130a-3p and cerebrovascular events was analyzed using a Kaplan–Meier method, and a logistic risk model was constructed for 2-year cerebrovascular events. Results Cerebral AS patients had elevated serum miR-130a-3p compared with controls (P

We sought to develop a new simple but effective tool for estimating surgical risk.Patients and Methods: Using a nested case-control study design, we recruited 105 patients who experienced MACCEs and 481 patients without MACCEs during hospitalization from 10,507 patients undergoing major noncardiac surgery in Beijing Chaoyang hospital. Least absolute shrinkage and selection operator (LASSO) regression and likelihood ratio were applied to screen 401 potential features for logistic regression. A nomogram was constructed using the selected variables.Results: Chronic heart failure, valvular heart disease, preoperative serum creatinine > 2.0 mg/dL, ASA class, neutrophil count and age were most associated with in-hospital MACCEs among all the factors. A new prediction model established based on these showed a good discriminatory ability (AUC, 0.758 [95% confidence interval (CI), 0.708– 0.808] and a well-performed calibration curve (Hosmer–Lemeshow χ2 = 7.549, p = 0.479), which upheld in the 10-fold cross-validation (AUC, 0.742 [95% CI, 0.718– 0.767]. This model also demonstrated an improved performance in comparison to the modified Revised Cardiac Risk Index (RCRI) score (increase in AUC by 0.119 [95% CI, 0.056– 0.180]; NRI, 0.445 [95% CI, 0.237– 0.653]; IDI, 0.133 [95% CI, 0.087– 0.178]. The decision curve analysis showed a positive net benefit of our new model.Conclusion: Our nomogram, which relies upon simple clinical characteristics and laboratory tests, is able to predict MACCEs in patients undergoing major noncardiac surgery. This prediction shows better discrimination than the standardized modified RCRI score, laying a promising foundation for further large-scale validation.Keywords: major adverse cardiovascular events, cerebrovascular events, perioperative period, risk assessment, cardiac risk indexes

Background: Carotid artery stenosis (CAS) may cause many cerebrovascular diseases, and a biomarker for screening and monitoring is needed. This study focused on the clinical significance of long-chain non-coding RNA (lncRNA) non-coding RNA activated by DNA damage (NORAD) in patients with CAS and aimed to search for potential biomarkers of CAS., Methods: Eighty-six asymptomatic patients with CAS and 60 healthy individuals were enrolled, with corresponding clinical data and serum samples collected. The expression of NORAD was detected by reverse transcription-quantitive PCR (RT-qPCR). All patients were followed up for 2 years to collected the occurrence data of cerebrovascular events, and Kaplan-Meier and Cox regression were used for data analysis. Receiver operator characteristic curve was used to analyze the diagnostic value of NORAD in distinguishing CAS patients from healthy people, and to evaluate the prediction accuracy of NORAD., Results: NORAD is overexpressed in the serum of CAS patients, and associated with patients' hypertension, TC, LDL-C levels and stenosis degree. NORAD has high sensitivity (88.37%) and specificity (80.00%) in the identification of CAS patients (AUC = 0.917). NORAD was independently related to the occurrence of cerebrovascular events (HR = 2.435, P  = .003). a logistic regression risk model for predicting cerebrovascular events was constructed with the parameters including NORAD, TC and LDL., Conclusion: NORAD can be used as a diagnostic and prognostic biomarker for CAS, and NORAD, total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C) can be independently correlated to predict cerebrovascular events., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Lenvatinib is the standard treatment for radioiodine-refractory differentiated thyroid cancer (RR-DTC). Thromboembolic (TE) side effects are quite rare (1–3% of treated patients) in clinical trials. Nevertheless, patients with predisposing factors are at a higher risk of developing cardiovascular adverse events. Reduction of lenvatinib starting dose and cardiologic counselling to provide appropriate supportive therapies are usually recommended for high-risk patients. From 2016 to 2022, we analyzed a series of 16 patients who were consecutively treated at our institution. All except one patient received a reduction in their dosage after two cycles of therapy because of toxicities, and four patients (25%) suffered from TE. The observed incidence in our patient sample seemed to be higher than expected. We hypothesized that our patient sample might be at higher risk probably because of the heavy prior loco-regional treatments performed. [ABSTRACT FROM AUTHOR]

Asymptomatic patients with a remote history of transient ischemic attack (TIA) or stroke are not well studied as a separate population from asymptomatic patients with no prior history of TIA or stroke. We compared in-hospital outcomes after transcarotid artery revascularization (TCAR) and transfemoral carotid artery stenting (TFCAS) among symptomatic patients, patients with a remote history of neurologic symptoms, and asymptomatic patients. Data from patients in the Vascular Quality Initiative database who underwent TCAR (January 2017 to April 2020) or TFCAS (May 2005 to April 2020) were analyzed. Symptomatic status was defined as TIA and/or stroke occurring within 180 days before the procedure. Asymptomatic status was divided into patients with no history of TIA/stroke (asymptomatic) and patients with a history of TIA/stroke occurring more than 180 days before the procedure (remote history of neurologic symptoms). The Student t -test and Pearson χ2 test were used to compare baseline patient characteristics and outcomes. Multivariate logistic regression was used to adjust for significant between-group differences in baseline characteristics. There were 7158 patients who underwent TCAR (symptomatic: 2574, asymptomatic: 3689, and asymptomatic with a remote history of neurologic symptoms: 895) and 18,023 patients who underwent TFCAS (symptomatic: 6195, asymptomatic: 10,333, and asymptomatic with a remote history of neurologic symptoms: 1495). Regardless of symptom status, the mean patient age was 73 years for TCAR and 69 years for TFCAS. A total of 64% of patients in the study were male and 36% of patients were female. The mean long-term follow-up data ranged between 208 and 331 days within the three patient groups. Carotid stenosis patients with a remote history of neurologic symptoms had higher rates of TIA, stroke, TIA/stroke, stroke/death, and stroke/death/myocardial infarction than asymptomatic patients, and these rates were similar to those of symptomatic patients. Comparing TCAR and TFCAS among patients with a remote history of neurologic symptoms, there were statistically significant reductions in the odds of stroke/death (odds ratio: 0.46, 95% confidence interval: 0.27-0.84, P =.011) and stroke/death/myocardial infarction (odds ratio: 0.51, 95% confidence interval: 0.30-0.87, P =.013) after TCAR. This was likely driven by the increased rate of death after TFCAS in patients with a remote history of neurologic symptoms (0.9%) compared with asymptomatic patients (0.6%). Asymptomatic patients with a remote history of TIA/stroke do not have the same outcomes as asymptomatic patients without a history of TIA/stroke and are at higher risk of adverse in-hospital events. Patients with a remote history of TIA/stroke have increased risk of in-hospital death after TFCAS and may benefit from TCAR. [ABSTRACT FROM AUTHOR]

Background: Disparities in treatment and outcomes of infective endocarditis (IE) between people who use drugs (PWUD) and non-PWUD have been reported, but long-term data on cardiovascular and cerebrovascular outcomes are limited. We aim to compare 5-year rates of mortality, cardiovascular and cerebrovascular events after IE between PWUD and non-PWUD. Methods: Using data from the TriNetX Research Network, we examined 5-year cumulative incidence of mortality, myocardial infarction, heart failure, atrial fibrillation/flutter, ventricular tachyarrhythmias, ischemic stroke, and intracranial hemorrhage in 7132 PWUD and 7132 propensity score-matched non-PWUD patients after a first episode of IE. We used the Kaplan–Meier estimate for incidence and Cox proportional hazards models to estimate relative risk. Results: Matched PWUD were 41 ± 12 years old; 52.2% men; 70.4% White, 19.8% Black, and 8.0% Hispanic. PWUD had higher mortality vs. non-PWUD after 1 year (1–3 year: 9.2% vs. 7.5%, p = 0.032; and 3–5-year: 7.3% vs. 5.1%, p = 0.020), which was largely driven by higher mortality among female patients. PWUD also had higher rates of myocardial infarction (10.0% vs. 7.0%, p < 0.001), heart failure (19.3% vs. 15.2%, p = 0.002), ischemic stroke (8.3% vs. 6.3%, p = 0.001), and intracranial hemorrhage (4.1% vs. 2.8%, p = 0.009) compared to non-PWUD. Among surgically treated PWUD, interventions on the tricuspid valve were more common; however, rates of all outcomes were comparable to non-PWUD. Conclusions: PWUD had higher 5-year incidence of cardiovascular and cerebrovascular events after IE compared to non-PWUD patients. Prospective investigation into the causes of these disparities and potential harm reduction efforts are needed. [ABSTRACT FROM AUTHOR]

BackgroundLong-term risk and predictors of cerebrovascular events following sepsis hospitalization have not been clearly elucidated. We aim to determine the association between surviving sepsis hospitalization and cerebrovascular complications in adult sepsis survivors.MethodWe searched MEDLINE, Embase, Scopus, Web of Sciences, Cochrane library, and Google scholar for studies published from the inception of each database until 31 August 2022.ResultsOf 8,601 screened citations, 12 observational studies involving 829,506 participants were analyzed. Surviving sepsis hospitalization was associated with a significantly higher ischemic stroke [adjusted hazard ratio (aHR) 1.45 (95% CI, 1.23–1.71), I2 = 96], and hemorrhagic stroke [aHR 2.22 (95% CI, 1.11–4.42), I2 = 96] at maximum follow-up compared to non-sepsis hospital or population control. The increased risk was robust to several sensitivity analyses. Factors that were significantly associated with increased hazards of stroke were: advanced age, male gender, diabetes mellitus, hypertension, coronary artery disease, chronic heart failure, chronic kidney disease, chronic obstruction pulmonary disease, and new-onset atrial fibrillation. Only diabetes mellites [aHR 1.80 (95% CI, 1.12–2.91)], hypertension [aHR 2.2 (95% CI, 2.03–2.52)], coronary artery disease [HR 1.64 (95% CI, 1.49–1.80)], and new-onset atrial fibrillation [aHR 1.80 (95% CI, 1.42–2.28)], were associated with > 50% increase in hazards.ConclusionOur findings showed a significant association between sepsis and a subsequent risk of cerebrovascular events. The risk of cerebrovascular events can be predicated by patient and sepsis-related baseline variables. New therapeutic strategies are needed for the high-risk patients.

Antiplatelet therapy is key to prevent recurrences in patients with an acute or prior non-cardioembolic stroke or transient ischemic attack (TIA). The narrow balance between the risks of ischemic recurrence and major bleeding is a relevant clinical dilemma in this population. This review covers the current evidence on antiplatelet therapy for patients with non-cardioembolic stroke or TIA. Randomized controlled trials of antithrombotic strategies for patients with these conditions were searched in Pubmed/Medline from 1970 to 2022. Numerous randomized controlled trials have defined the current indications to the use of antiplatelet drugs for patients with non-cardioembolic ischemic stroke or TIA. For the management of these subjects, single antiplatelet therapy with aspirin or clopidogrel, or the combination of aspirin and dipyridamole, is usually recommended. After an acute stroke or TIA, a short course of dual antiplatelet therapy with aspirin in combination with clopidogrel or ticagrelor should be considered. The risk of bleeding might be higher with ticagrelor, but a direct comparison with clopidogrel is not available in this setting. The introduction of newer strategies, such as dual-pathway inhibition with aspirin and a direct oral anticoagulant (including emerging factor XI inhibitors under clinical development) may open a new research avenue in this challenging area.

Background: Cerebral atherosclerosis (AS) leads to high risk of cerebrovascular events. This study aims to evaluate the diagnostic performance of serum microRNA-130a-3p (miR-130a-3p) in cerebral AS patients, and construct a logistic risk model for 2-year cerebrovascular events on the basis of the prognostic potential of miR-130a-3p.Methods: Serum samples were collected from 74 cerebral AS patients and 62 control individuals, and miR-130a-3p expression was investigated using reverse transcription quantitative PCR. Risk factors related with cerebral AS were assessed using a logistic regression analysis, and the receiver operating characteristic analysis was performed to evaluate the diagnostic value of miR-130a-3p. The relationship between miR-130a-3p and cerebrovascular events was analyzed using a Kaplan-Meier method, and a logistic risk model was constructed for 2-year cerebrovascular events.Results: Cerebral AS patients had elevated serum miR-130a-3p compared with controls (P < 0.001). Serum miR-130a-3p had diagnostic value (AUC = 0.899), and could significantly improve the diagnostic accuracy of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in cerebral AS patients (AUC = 0.992). High serum miR-130a-3p was independently related with high probability of cerebrovascular events (HR = 1.993, 95% CI = 1.205-2.897, P = 0.006), and a logistic risk model was constructed based on serum miR-130a-3p, hs-CRP, TC and LDL-C.Conclusion: All the findings indicated that high serum miR-130a-3p had diagnostic potential to screen cerebral AS, and predicted the probability of cerebrovascular events after AS. The logistic risk model based on miR-130a-3p may provide an efficient method to predict 2-year cerebrovascular events in AS patients. [ABSTRACT FROM AUTHOR]

Background: Vinpocetine as a neuroprotective agent is effective in acute ischemic stroke in some randomized controlled trials (RCTs). Since the last systematic review has been published in 2008, which didn't find conclusive evidence favoring its use, two more RCTs have also been completed. Methods: Relevant electronic databases were searched with a suitable combination of Medical Subject Headings terms to detect publications describing RCTs exploring the safety and efficacy of vinpocetine in patients with acute ischemic stroke. The risk of bias was determined by using the Cochrane Collaboration's tool for assessing the risk of bias in RCTs after full-text review and relevant data extraction. Higgins and Thompson's I2 method was used to assess heterogeneity in studies. The presence of publication bias was assessed by Egger's test. We used a random effect model when I2 was more than 50% and a fixed-effect model for other parameters. Results: Four placebo-controlled RCTs enrolling a total of 601 and 236 patients in vinpocetine and placebo groups, respectively, were included. The number of patients with death or significant disability was lower in the vinpocetine group than that in the placebo group at both 1 and 3 months (relative risk 0.80, 95% confidence interval [CI] 0.65–0.99 and relative risk 0.67, CI 0.48–0.92, p = 0.04 and 0.02, respectively). The degree of disability in participants at 1 month and 3 months was also lower in vinpocetine group than that in the placebo group (standardized mean difference (SMD) 0.49, 95% CI 0.03–0.95 and SMD 1.22, CI 0.23–2.24, p = 0.001 and 0.04, respectively). Change in mini-mental state examination score compared with baseline at trial enrolment was also better in the vinpocetine group than in the placebo group (pooled weighted mean difference 0.92, 95% CI 0.02–1.82, p = 0.04). Conclusions: Vinpocetine has some promising efficacy in patients with ischemic stroke when used in the acute stage in reducing the disability, but presently there is not enough evidence to suggest that it also reduces case fatality. More double-blind, placebo-controlled RCTs of adequate sample size are needed before making recommendations for the routine administration of vinpocetine for all patients with acute ischemic stroke.

Background: Atrial fibrillation (AF) is associated with an increased risk of heart failure (HF), stroke, and death. Although fibrillation cycle length (FCL) is used as a surrogate for atrial refractoriness, its impact on outcomes remains unclear. This study aimed to identify predictors of cardiovascular events, including FCL, in patients with long-standing persistent AF. Methods: The study included 190 consecutive patients with long-standing persistent AF (mean age 74 years, 74% male). Patients with valvular AF or hemodialysis-dependent end-stage renal disease and those on anti-arrhythmic drugs were excluded. The primary composite outcome was occurrence of cardiovascular events (myocardial infarction, HF), cerebrovascular events (stroke, transient ischemic attack), and all-cause death. FCL was calculated by fast Fourier transformation analysis of fibrillation waves in the surface electrocardiogram. Results: Over a median follow-up of 2.6 years, the primary outcome occurred in 31 patients (cardiovascular events, n = 18; cerebrovascular events, n = 8; all-cause death, n = 5). In multivariate analysis, longer FCL and history of HF were independent predictors of these outcomes. In a Cox proportional hazards model adjusted for age, sex, and history of HF, patients with an FCL > 160 ms (cut-off determined by receiver-operating characteristic curve analysis) were at increased risk of the outcome (hazard ratio 12.9; 95% confidence interval 4.99–44.10; p < 0.001). Conclusions: FCL was independently associated with cardiovascular outcomes in patients with long-standing persistent AF. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed at retrospectively evaluating full-body computed tomography (CT) examinations for the prevalence of cerebrovascular events in patients with suspected sepsis treated in the intensive care unit (ICU). Methods: All full-body CT examinations, i.e., both cranial CT (cCT) and body CT including chest, abdomen and pelvis, for focus search in septic patients over a 12-months period were identified from three ICUs, using full-text search. From this retrospective cohort, we fully analyzed 278 cCT examinations for the occurrence of acute cerebral findings. All acute cerebrovascular events were independently reviewed by two blinded readers. Clinical and laboratory findings were extracted. The data were statistically analyzed using contingency tests. Results: In our population of patients with suspected sepsis, 10.8% (n = 30/278) were identified to have major cerebral events, including 7.2% (n = 20/278) major cerebrovascular events and 4.3% (n = 12/278) generalized parenchymal damage. 13.4% (n = 22/163) of patients with a severe coma as compared with non-severe coma, 4.4% (n = 3/68), showed a major cerebral event (p = 0.04). Patients referred from the cardiology/nephrology ICU ward showed major cerebral events in 16.3% (n = 22/135), as compared with 4.9% (n = 3/61) in patients from pulmonary ICU and 6.1% (n = 5/82) major cerebral events with surgical referral (p = 0.02). Conclusion: Our study provides further evidence that septic patients may suffer from cerebral events with relevance to their prognosis. Severe coma and the referring ward were associated with acute cerebral conditions. Full-body CT has the advantage of both detecting of septic foci and possibly identifying ischemic or hemorrhagic stroke in this vulnerable patient population. [ABSTRACT FROM AUTHOR]

BackgroundMoyamoya is a rare progressive cerebral arteriopathy, occurring as an isolated phenomenon (moyamoya disease, MMD) or associated with other conditions (moyamoya syndrome, MMS), responsible for 6–10% of all childhood strokes and transient ischemic attacks (TIAs).MethodsWe conducted a retrospective multicenter study on pediatric-onset MMD/MMS in Italy in order to characterize disease presentation, course, management, neuroradiology, and outcome in a European country.ResultsA total of 65 patients (34/65 women) with MMD (27/65) or MMS (38/65) were included. About 18% (12/65) of patients were asymptomatic and diagnosed incidentally during investigations performed for an underlying condition (incMMS), whereas 82% (53/65) of patients with MMD or MMS were diagnosed due to the presence of neurological symptoms (symptMMD/MMS). Of these latter, before diagnosis, 66% (43/65) of patients suffered from cerebrovascular events with or without other manifestations (ischemic stroke 42%, 27/65; TIA 32%, 21/65; and no hemorrhagic strokes), 18% (12/65) of them reported headache (in 4/12 headache was not associated with any other manifestation), and 26% (17/65) of them experienced multiple phenotypes (≥2 among: stroke/TIA/seizures/headache/others). Neuroradiology disclosed ≥1 ischemic lesion in 67% (39/58) of patients and posterior circulation involvement in 51% (30/58) of them. About 73% (47/64) of patients underwent surgery, and 69% (45/65) of them received aspirin, but after diagnosis, further stroke events occurred in 20% (12/61) of them, including operated patients (11%, 5/47). Between symptom onset and last follow-up, the overall patient/year incidence of stroke was 10.26% (IC 95% 7.58–13.88%). At last follow-up (median 4 years after diagnosis, range 0.5–15), 43% (26/61) of patients had motor deficits, 31% (19/61) of them had intellectual disability, 13% (8/61) of them had epilepsy, 11% (7/61) of them had behavioral problems, and 25% (13/52) of them had mRS > 2. The proportion of final mRS > 2 was significantly higher in patients with symptMMD/MMS than in patients with incMMS (p = 0.021). Onset age 2 at follow-up (p = 0.0106 and p = 0.0009, respectively).ConclusionsMoyamoya is a severe condition that may affect young children and frequently cause cerebrovascular events throughout the disease course, but may also manifest with multiple and non-cerebrovascular clinical phenotypes including headache (isolated or associated with other manifestations), seizures, and movement disorder. Younger onset age and stroke before diagnosis may associate with increased risk of worse outcome (final mRS > 2).

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the novel coronavirus that is causing the ongoing coronavirus disease 2019 (COVID-19) pandemic, was first reported in late 2019. Since then, an unprecedented amount of new knowledge has emerged about this virus and its treatment. Although the reported symptoms of COVID-19 are primarily respiratory with acute respiratory distress syndrome, SARS-CoV-2 has also been shown to affect other organs, including brain, and there are growing reports of neuropsychiatric symptoms due to COVID-19. There are two suggested pathways for how COVID-19 can affect the brain and mind: the direct impact on the brain and impact mediated via stress. Direct impact on the brain is manifested as encephalitis/encephalopathy with altered mental status (AMS) and delirium. In this paper, we summarize evidence from studies of previous outbreaks and current data from the COVID-19 pandemic that describe how COVID-19 is associated with an increased prevalence of anxiety, stress, poor sleep quality, obsessive-compulsive symptoms, and depression among the general population during the pandemic. In addition, we summarize the current evidence that supports how COVID-19 can also impact the CNS directly and result in delirium, cerebrovascular events, encephalitis, unspecified encephalopathy, AMS, or peripheral neurologic disorders.

Objective: White matter lesions (WMLs) increase the risk of stroke, stroke recurrence, and death. Higher plasma aldosterone concentration (PAC) increases the risk of stroke, acute myocardial infarction, and hypertension. The objective is to evaluate the relationship between PAC and cerebrovascular events in patients with hypertension and WMLs., Methods: We conducted a retrospective cohort study that included 1041 participants hospitalized. The outcome was new-onset cerebrovascular events including intracerebral hemorrhage and stroke. A Cox regression model was used to evaluate the relationship between baseline PAC and the risk of cerebrovascular events., Results: The mean age of participants was 60.9 ± 10.2 years and 565 (53.4%) were males. The median follow-up duration was 42 months (interquartile range: 25-67), and 92 patients experienced new-onset cerebrovascular events. In a multivariate-adjusted model, with PAC as a continuous variable, higher PAC increased the risk of cerebrovascular events; patient risk increased per 1 (hazard ratio [HR: 1.03], 95% confidence interval [CI]: 1.01-1.06, P < .01), per 5 (HR: 1.17, 95% CI: 1.06-1.31, P < .01), and per 10 ng/dL (HR: 1.41, 95%: 1.14-1.75, P < .01) increase in PAC. When PAC was expressed as a categorical variable (quartile: Q1-Q4), patients in Q4 (HR: 2.12, 95% CI: 1.18-3.79, P < .05) exhibited an increased risk of cerebrovascular events compared to Q1. Restrictive spline regression showed a linear association between PAC and the risk of new-onset cerebrovascular events after adjusting for all possible variables., Conclusions: Our study identified a linear association between PAC and the risk of new-onset cerebrovascular events in patients with hypertension and WMLs., Competing Interests: Disclosure The authors have no multiplicity of interest to disclose., (Copyright © 2024 AACE.

Microvasculature of the retina is considered an alternative marker of cerebral vascular risk in healthy populations. However, the ability of retinal vasculature changes, specifically focusing on retinal vessel diameter, to predict the recurrence of cerebrovascular events in patients with ischemic stroke has not been determined comprehensively. While previous studies have shown a link between retinal vessel diameter and recurrent cerebrovascular events, they have not incorporated this information into a predictive model. Therefore, this study aimed to investigate the relationship between retinal vessel diameter and subsequent cerebrovascular events in patients with acute ischemic stroke. Additionally, we sought to establish a predictive model by combining retinal veessel diameter with traditional risk factors. We performed a prospective observational study of 141 patients with acute ischemic stroke who were admitted to the First Affiliated Hospital of Jinan University. All of these patients underwent digital retinal imaging within 72 hours of admission and were followed up for 3 years. We found that, after adjusting for related risk factors, patients with acute ischemic stroke with mean arteriolar diameter within 0.5-1.0 disc diameters of the disc margin (MAD 0.5-1.0DD ) of ≥ 74.14 μm and mean venular diameter within 0.5-1.0 disc diameters of the disc margin (MVD 0.5-1.0DD ) of ≥ 83.91 μm tended to experience recurrent cerebrovascular events. We established three multivariate Cox proportional hazard regression models: model 1 included traditional risk factors, model 2 added MAD 0.5-1.0DD to model 1, and model 3 added MVD 0.5-1.0DD to model 1. Model 3 had the greatest potential to predict subsequent cerebrovascular events, followed by model 2, and finally model 1. These findings indicate that combining retinal venular or arteriolar diameter with traditional risk factors could improve the prediction of recurrent cerebrovascular events in patients with acute ischemic stroke, and that retinal imaging could be a useful and non-invasive method for identifying high-risk patients who require closer monitoring and more aggressive management., Competing Interests: None

BACKGROUND: Outcome and management differ depending on localisation and extent of aortic dissection. Malperfusion sydrome may be associated with reduced survival for patients with acute type 1 aortic dissection. Coronary and neurologic malperfusions may present high-risk subgroups. Malperfusion syndromes may benefit from immediate open aortic repair to restore true lumen perfusion. METHOD: A total of 81 patients were analysed retrospectively in the study who underwent surgery between 2013 and 2023 in our third-care hospital. From 81 type 1 aortic dissection patients, 12 patients had total arch replacement, 16 patients had Bentall operation and the others had ascending aorta and hemiarch replacement. From these 81 dissection patients, the cerebrovascular complications were evaluated in the follow-up period at least two years after primary surgery. Results: The two patients had cerebrovascular events at the long-term follow-up period. Conclusions: We should follow up the type 1 dissection patients who had the false lumen pathologies of the arch branches more curiously. The cerebrovascular event due to the false lumen thromboembolic sources are the main reason for these events. [ABSTRACT FROM AUTHOR]

Background: Antithrombotic therapy (ATT) in patients with infective endocarditis (IE) is challenging., Objectives: The authors evaluated the impact of anticoagulant and antiplatelet therapy on clinical endpoints in IE patients., Methods: We performed a systematic review and meta-analysis comparing IE patients with prior and/or ongoing use of ATT vs those without any ATT during IE course. Primary outcome was reported in-hospital cerebrovascular events. Secondary outcomes were in-hospital mortality, intracranial hemorrhage (ICH), systemic thromboembolism (ST), and mortality within 6 months., Results: Twelve studies, with a total of 12,151 patients, were included. The primary endpoint was not different comparing 10,115 IE patients with or without prior anticoagulation (OR: 1.10; 95% CI: 0.56-2.17; P  = 0.77) or comparing 838 IE patients with or without prior antiplatelet (OR: 0.90; 95% CI: 0.61-1.33; P  = 0.61). In-hospital mortality was lower in IE patients with prior anticoagulation compared to those without (OR: 0.74; 95% CI: 0.57-0.96; P  = 0.03). There was no difference in reported ICH rates between patients with or without prior anticoagulation (OR: 0.54; 95% CI: 0.27-1.09; P  = 0.09) or between patients with or without prior antiplatelet (OR: 0.35; 95% CI: 0.11-1.10; P  = 0.07). The rate of ST was lower in IE patients with prior antiplatelet therapy compared to those without (OR: 0.53; 95% CI: 0.38-0.72; P  < 0.01)., Conclusions: ATT in IE patients was not associated with higher frequency of cerebrovascular events or ICH. Moreover, we found that the use of anticoagulation was associated with decreased in-hospital mortality and the use of antiplatelets was associated with decreased ST. Due to the limitations of this study, these results should be interpreted cautiously showing the necessity of a randomized setup., Competing Interests: Dr Caldonazo was funded by the 10.13039/501100001659Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) Clinician Scientist Program OrganAge funding number 413668513, by the 10.13039/501100005971Deutsche Herzstiftung (DHS, German Heart Foundation) funding number S/03/23 and by the Interdisciplinary Center of Clinical Research of the Medical Faculty Jena.

Objective: To assess the prevalence and impact of cerebrovascular risk factors (CRF) on cerebrovascular events (CVE) in patients with giant cell arteritis (GCA)., Methods: Analysis of the patients diagnosed with GCA identified in the Spanish Hospital Discharge Database between 2016 and 2018., Results: 8,474 hospital admissions from patients diagnosed with GCA were identified. 3.4% of the admissions were motivated by CVE (stroke in 2.8% and transient ischemic attack in 0.6%). When compared with the admissions due to other causes, the patients who suffered from CVE presented a higher rate of male sex (36.2% vs 43.5%, p=0.007), hypertension (66.9% vs 74.4%, p=0.004), diabetes (27.6% vs 33.7%, p=0.016) and atherosclerosis (6.6% vs 10.2%, p=0.0.017). After adjustment, male sex (OR=1.35, 95% CI 1.06-1.72) and mainly hypertension (OR=1.44, 95% CI 1.11-1.90) were associated with a higher risk of CVE., Conclusion: Hypertension, along with male sex, was the strongest risk factor for cerebrovascular events in GCA patients. In these high-risk patients, antiplatelet therapy should be re-considered and evaluated in prospective studies., (Copyright © 2023 The Author(s). Published by Elsevier España, S.L.U.

Transcatheter aortic valve replacement (TAVR) has become a first-line treatment for severe aortic stenosis with intermediate to high-risk population with its use increasingly expanding into younger and low-risk cohorts as well. Cerebrovascular events are one of the most serious consequential complications of TAVR, which increase morbidity and mortality. The most probable origin of such neurological events is embolic in nature and the majority occur in the acute phase after TAVR when embolic events are most frequent. Cerebral embolic protection devices have been designed to capture or deflect these emboli, reducing the risk of peri-procedural ischaemic events. They also carry the potential to diminish the burden of new silent ischemic lesions during TAVR. Our review explores different types of these device systems, their rationale, and the established clinical data., Competing Interests: Disclosure: The authors have no conflicts of interest to declare., (Copyright © The Author(s), 2023.
