Background. Lacunar stroke (LS) accounts for a quarter of all ischemic strokes and is considered to have a benign prognosis. However, 20-30% of patients experience worsening of neurological deficit in hours or days after stroke onset. Mechanisms of progression are not known and no reliable clinical predictor has been identified. Aim of this study was to explore vascular risk factors and baseline clinical or laboratory features potentially associated with progression in LS. Methods. We performed a retrospective analysis of consecutive patients with LS admitted to the Stroke Unit of Careggi University Hospital (Florence, Italy) between January 2002 and December 2010. Patients were included in the study if they presented with a lacunar syndrome according to OCSP classification and/or small vessel disease according to TOAST classification and/or a lacunar infarct on neuroimaging consistent with the clinical deficit. Patients were divided into “progressive” and “non progressive”. Progression was defined as an increase of at least one point on one of the motor items of the NIHSS during the first 72 hours after stroke onset. Factors associated with progression after univariate analysis were entered into a multiple logistic regression model in order to select independent determinants of progression. Results. Out of 1502 patients with ischemic stroke admitted during the study period, 156 met the inclusion criteria. Thirty-nine (25%) patients showed neurological worsening. Latency of progression was 25.7 hours. Patients who progressed were younger than those who did not (mean age: 67.9±10.7 vs 70.6±13.0). There were no significant differences for single vascular risk factors distribution, laboratory parameters and baseline stroke severity comparing the two groups. When considering the presence of one versus more than one factor among hypertension, diabetes, smoking and hypercholesterolemia, the risk of progression increased with increasing number of risk factors: neurological worsening was observed in 0% (0/17) of patients with no risk factor, 24% (15/62) of those with one risk factor and 31% (24/77) of those with more than one risk factor (p=0.025). After adjustment for univariate predictors (age, sex, diastolic hypertension and lesion location in pons or internal capsule), the presence of multiple vascular risk factors maintained an independent effect on progression: risk of progression increased with an OR=1.7 (95%IC=1.1-2.8) for any additional risk factor. Conclusion. Our results suggest that a high risk factors profile is associated with an increased risk of progression. Translating this observation into a hypothetical pathological setting, it could support the hypothesis of mural atheroma involving the parent artery and proximal portion of the perforating arteries, eventually leading to the progressive enlargement of the ischemic area as a putative mechanism of progressive LS.

Objective: To determine risk factors in different pathogenic subtypes of ischemic stroke in Tashkent hospital registry and to compare with the data of other stroke registers.Design: Prospective observational study.Participants: 300 adults aged 18 years or over who suffered first-ever acute ischemic stroke, of them, the data of 100 patients with atherothrombotic, lacunar and cardioembolic strokes were analyzed.Main outcome measures: Mathematically significant differences and not significant differences but interesting from other point of view. Categorical variables are expressed as frequencies and percentages. Differences were regarded as statistically significant when the P value was less than 0.05 (P<0.05).Results: Of 100 patients with acute first-ever ischemic stroke at the median age of 62.63±4.68 (interquartile range 25-92) years, 57% were men and 43% were women. Depending on aetiology and stroke subtype, all the patients were divided into three groups: 42 patients with atherothrombotic stroke, 41 – with lacunar stroke, and 17 patients with cardioembolic stroke. Atherothrombotic stroke developed often in people over 60 years old, while lacunar stroke prevailed at the younger age. Stroke cases increased in people over 51 years old. Although men were more likely to suffer strokes than women, stroke incidence was equal in both sexes with increasing of age (over 60 years old), especially in atherothrombotic stroke, testifying to that women live longer. Combination of cerebral atherosclerosis and hypertension was the most significant risk factor for stroke. Atherosclerosis was the main aetiological factor for ischemic stroke, independently of its pathogenic heterogeneity. Diabetes mellitus was an independent risk factor for all stroke subtypes, which in most cases worsened the course and outcome of stroke. Hypertension was the leader aetiological factor for lacunar stroke. In these patients, we also should consider the presence of other risk factors, e.g. severe large vessel obstructions, se-triglycerol ≥2 mmol/L, etc. Cardioembolic stroke developed mainly because of cardiac thrombosis and valve pathology, which were often associated with chronic diseases of other organs, worsening the course and outcome of stroke. Despite of high prevalence of myocardial infarction in men, women were more likely to develop cardioembolic stroke.Conclusions: This study found simultaneous influence of many risk factors (multifactorial disease) in the development of ischemic stroke. The more course and influence of the underlying disease and risk factor, the higher stroke risk and severity, especially in the absence or inadequate previous therapy of underlying disease before the stroke index. We have noted a high prevalence of under-diagnosis of vascular risk factors at levels of primary and secondary care. We recommend for improved public awareness of vascular risk factors and better diagnostic and treatment facilities aimed at addressing those factors at levels of primary and secondary healthcare. Larger population-based studies may provide additional data on stroke incidence and outcome among Uzbeks.

Introduction: Cerebral vein thrombosis (CVT) is associated with an increased risk of subsequent venous thromboembolism. It is unknown whether the risk of pulmonary embolism (PE) after CVT is similar to that of PE after deep venous thrombosis (DVT). Methods: We performed a retrospective cohort study using administrative claims data from all emergency department visits and hospitalizations in California from 2005-2011, New York from 2006-2013, and Florida from 2005-2013. We identified patients with CVT or DVT as well as the primary outcome of PE using previously validated International Classification of Diseases, Ninth Revision, Clinical Modification ( ICD-9-CM ) codes. In order to minimize misclassification error, patients with both CVT and DVT during the same index hospitalization were excluded and patients with CVT were censored at the time of development of DVT and vice versa. Kaplan-Meier survival statistics and Cox proportional hazards models were used to compare the risk of PE after CVT versus after DVT while adjusting for demographics, vascular risk factors, and the Elixhauser comorbidity index. Results: We identified 4,450 patients with CVT and 217,589 patients with DVT. During a mean follow-up of 2.0 (±1.7) years, 124 patients with DVT developed a PE and 18,698 patients with DVT developed a PE. Patients with CVT were younger (mean age 45 vs 63), more often female (71% vs 52%), more often pregnant, and had fewer vascular risk factors than patients with DVT. During the index hospitalization, the rate of PE was 1.5% (95% confidence interval [CI], 1.1-1.8%) in patients with CVT and 6.2% (95% CI, 6.1-6.3%, p<0.001) in patients with DVT. By 5 years, the cumulative rate of PE after CVT was 3.7% (95% CI, 3.0-4.4%) compared to 10.5% (95% CI, 10.3-10.6%, p<0.001) after DVT. After adjustment for demographics and comorbidities, CVT was associated with a significantly lower hazard of PE when compared to DVT (hazard ratio, 0.31; 95% CI, 0.26-0.38). Conclusion: In a large, heterogeneous population, we found that the risk of PE after CVT was significantly lower than that of PE after DVT. Among patients with CVT, the greatest risk for PE was apparent during the index hospitalization.

Introduction: The AHA notes that more than 76% of strokes are the first occurrence. There are class 1 recommendations for the management of common risk factors such as atrial fibrillation (AF), hyperlipidemia (HLD), hypertension (HTN), diabetes (DM), and vascular disease. The purpose of this study is to investigate the percentage of large vessel strokes that are potentially preventable with adequate management of vascular risk factors. Methods: A retrospective chart review was conducted on all patients undergoing endovascular therapy (EVT) from 2012-2019. Data was collected on vascular risk factors present prior to admission including HTN, DM, HLD, AF, and smoking. Preventable stroke was defined as having at least one of the following: untreated AF, untreated HLD, poorly controlled HTN (presence of left ventricular hypertrophy on transthoracic echo), history of vascular disease not on an antiplatelet agent, poorly controlled DM (A1c>10), current smoking. Groups were compared based on age, sex and 90 day functional outcomes, with favorable outcome defined as mRS ≤ 2. Results: Our sample included 396 patients who underwent EVT (mean age 65, 50% female). 42% of patients with Afib were not on anticoagulation, 31% of patients with HLD were untreated, 39% of patients with HTN were poorly controlled, 27% of patients with a history of vascular disease were not on an antiplatelet, 14% of patients with DM were poorly controlled, and 46% of all patients were smokers. In total, 78% of patients had at least 1 poorly controlled risk factor and 37% had at least 2. There was no difference in rates of preventable stroke between males and females (48% vs 52%, p=0.30) and between age groups above and below 70 (40% vs 60%, p=0.68). 64% of patients with well controlled risk factors had a favorable outcome compared to 51% with at least one poorly controlled risk factor (p=0.03). Conclusions: Our data suggests that despite guidelines on management of vascular risk factors, a large number of these are poorly controlled prior to admission for large vessel stroke, leading to a potentially preventable procedure. Not only could improved primary prevention save the wide array of resources utilized in EVT, but it could also influence long term outcomes in this cohort of patients.

ObjectiveGiven the potential therapeutic effect of vascular disease control timing to reduce dementia risk, we investigated the age-related influences of vascular risk factor burden on brain structure throughout the lifespan.MethodsWe studied participants from the community-based prospective Framingham Heart Study. Overall vascular risk factor burden was calculated according to the Framingham Stroke Risk Profile, a validated algorithm that predicts stroke risk. Brain volume was estimated by MRI. We used cross-sectional data to examine how the strength of association between vascular risk factor burden and brain volume changed across each age decade from age 45–54 years through to 85–94 years (N = 2,887). Second, we leveraged up to 40 years of longitudinal data to determine how the strength of association between vascular risk factor burden and brain volume changed when vascular risk factors were examined at progressively earlier ages (N = 7,868).ResultsIn both cross-sectional and longitudinal analyses, higher vascular risk factor burden was associated with lower brain volume across each age decade. In the cross-sectional analysis, the strength of this association decreased with each decade of advancing age (p for trend < 0.0001). In longitudinal analysis, the strength of association between vascular risk factor burden and brain volume was stronger when vascular risk factors were measured at younger ages. For example, vascular risk factor burden was most strongly associated with lower brain volume in later life when vascular risk factors were measured at age 45 years.ConclusionVascular risk factors at younger ages appear to have detrimental effects on current and future brain volume.

Abstract BACKGROUND Patients with high-grade gliomas (HGG) often receive anti-angiogenic therapy with bevacizumab to slow disease progression and/or palliate neurological symptoms. Bevacizumab has been associated with an increased risk of two major vascular complications: venous thromboembolism (VTE) and intracranial hemorrhage (ICH). We sought to identify clinical, pathologic, and radiographic variables correlated with risk of either event occurring in patients with HGG receiving bevacizumab. METHODS We retrospectively identified 94 patients with HGG who received bevacizumab at our center from 2015-2021. Variables included demographics, performance status, IDH, MGMT, vascular risk factors, baseline anti-coagulant/anti-platelet use, concurrent chemotherapy, and presence of macrobleeds on MRI (&gt;1 cm3 susceptibility) at the time of bevacizumab initiation. We conducted competing risk analysis using subdistribution hazard models with death as competing risk for ICH or VTE. The effects of covariates on the incidence of hemorrhage or VTE were evaluated in univariate and multivariate settings. RESULTS Of 94 patients, 36 (38.3%) and 27 (28.7%) developed VTE and ICH, respectively. 31 (33%) did not develop either. ICH and VTE events occurred after a mean of 4.46 and 5.94 cycles of bevacizumab, respectively. 20 had baseline anti-platelet/anticoagulant use, and 16 had prior VTEs. Patients with macrobleeds on MRI had a larger HR of developing acute hemorrhage [HR=2.368 (1.112, 5.043), p=0.0254]. Patients older than 50 trended toward larger HR of developing VTE in univariate analysis that approached significance [HR=1.799 (0.889, 3.637), p=0.1023]. Sex, performance status, IDH, MGMT, vascular risk factors, baseline anticoagulant/anti-platelet use and concurrent chemotherapy were not significantly associated with occurrence of VTE. CONCLUSIONS The presence of macrobleeds on MRI is associated with increased risk of developing acute ICH while on bevacizumab. Older age at diagnosis of HGG may be associated with an increased risk of VTE in patients receiving bevacizumab. Larger studies are needed to confirm these findings.

Abstract Purpose of review To elucidate the intertwining of vascular events, vascular disease and vascular risk factors and COVID-19. Recent findings Strokes are a leading cause of disability and death worldwide. Vascular risk factors are important drivers of strokes. There are unmodifiable vascular risk factors such as age and ethnicity and modifiable vascular risk factors. According to the INTERSTROKE study, the 10 most frequent modifiable vascular risk factors are arterial hypertension, physical inactivity, overweight, dyslipidaemia, smoking, unhealthy diet, cardiac pathologies, diabetes mellitus, stress/depression and overconsumption of alcohol. Also, infection and inflammation have been shown to increase the risk of stroke. There is high-quality evidence for the clinical benefits of optimal primary and secondary stroke prevention. The COVID-19 pandemic brought a new perspective to this field. Vascular events, vascular disease and vascular risk factors—and COVID-19—are strongly intertwined. An increased risk of vascular events—by multifactorial mechanisms—has been observed in COVID-19 patients. Also, a higher rate of infection with COVID-19, severe COVID-19 and bad outcome has been demonstrated in patients with pre-existing vascular disease and vascular risk factors. Summary At present, we suggest that regular interactions between healthcare professionals and patients should include education on COVID-19 and on primary and secondary vascular prevention in order to reduce the burden of disease in our ageing populations.

Background: Understanding about risk factors of stroke based on its pathology is very important. Previous study about the vascular risk factors in patients with stroke in Indonesia is very limited.Aims and Objective: Measure the comparison between traditional vascular risk factors in patients with hemorrhagic stroke and non-hemorrhagic (ischemic) stroke.Materials and Methods: This was a nested case-control study using secondary data from electronic medical record and electronic stroke registry of Bethesda Hospital Yogyakarta Indonesia. The stroke was diagnosed with standard way by well-trained neurologist and confirmed with CT Scan. The traditional risk factors were defined systematically. We used Dupont Power and Sample Size calculation software and StatCal EpiInfo software with significance level 0,05.Result: The data of 200 subjects consisted of 100 patients with hemorrhagic stroke and 100 patients with non-hemorrhagic stroke. Hypertension was main vascular risk factor in both Group but it was more common in hemorrhagic stroke (OR: 2,528, 95% CI: 0,069 ; 0,316, p < 0,002). Dyslipidemia was a protective factor against hemorrhagic stroke (OR: 0,147, 95% CI: 1,415 ; 4,516, p < 0,001). Diabetes was more common in ischemic stroke compared with hemorrhagic stroke (68% and 32%) respectively.Conclusion: Hypertension, dyslipidemia, and diabetes were modifiable traditional vascular risk factors which significantly had effect on stroke. Asian Journal of Medical Sciences Vol.8(6) 2017 5-8

Introduction The impact of sleep disordered breathing (SDB) on arterial intima-media thickness (IMT), a surrogate measure for cardiovascular disease, remains uncertain, in part because of the potential for non-SDB vascular risk factor interactions. In the present study, we determined predictors for common carotid (CCA) and femoral (CFA) artery IMT in an adult, sleep clinic cohort where non-SDB vascular risk factors (particularly diabetes) were eliminated or controlled. Methods We recruited 296 participants for polysomnography (standard SDB severity metrics) and CCA/CFA ultrasound examinations, followed by a 12 month vascular risk factor minimisation (RFM) and continuous positive pressure (CPAP) intervention for participants with a range of SDB severity (RFM Sub-Group, n = 157; apnea hyponea index [AHI]: 14.7 (7.2–33.2), median [IQR]). Univariable and multivariable linear regression models determined independent predictors for IMT. Linear mixed effects modelling determined independent predictors for IMT change across the intervention study. P<0.05 was considered significant. Results Age, systolic blood pressure and waist:hip ratio were identified as non-SDB predictive factors for CCA IMT and age, weight and total cholesterol:HDL ratio for CFA IMT. No SDB severity metric emerged as an independent predictor for either CCA or CFA IMT, except in the RFM Sub-Group, where a 2-fold increase in AHI predicted a 2.4% increase in CFA IMT. Across the intervention study, CCA IMT decreased in those who lost weight, but there was no CPAP use interaction. CFA IMT, however, decreased by 12.9% (95%CI 6.8, 18.7%, p = 0.001) in those participants who both lost weight and used CPAP > = 4hours/night. Conclusion We conclude that SDB severity has little impact on CCA IMT values when non-SDB vascular risk factors are minimised or not present. This is the first study, however, to suggest a potential linkage between SDB severity and CFA IMT values.

Background and Purpose: Reports indicate an increased risk of ischemic stroke during coronavirus disease 2019 (COVID-19) infection. We aimed to identify patients with COVID-19 and ischemic stroke and explore markers of inflammation, hypercoagulability, and endotheliopathy, a structural and functional disturbance of the vascular endothelium due to a stressor. Methods: This was a retrospective, observational cohort study comparing acute ischemic stroke patients with and without COVID-19 across 3 hospitals. Timing of stroke onset during COVID-19 course and markers of inflammation, hypercoagulability, and endothelial activation were evaluated by COVID-19 status and stroke cause. Results: Twenty-one patients with ischemic stroke were diagnosed with COVID-19 during the study period. Patients with COVID-19 had a similar age and burden of vascular risk factors compared with the control cohort (n=168). We identified a temporal correlation between stroke onset and the peak of acute phase reactants, including CRP (C-reactive protein), ferritin, and d-dimer. In subsets of patients with labs available, embolic stroke of undetermined source was associated with elevated IL (interleukin)-6 (median, 171 [interquartile range, 13–375] versus 8 [4–11], P <0.01) and sIL (soluble IL)-2 receptor (1972 [1525–4720] versus 767 [563–1408.5], P =0.05) levels. Stroke patients with COVID-19 demonstrated elevated levels of endothelial activation markers compared with non-COVID-19 stroke controls (median von Willebrand activity 285.0% [interquartile range, 234%–382%] versus 150% [128%–183%], P =0.034; von Willebrand antigen 330.0% [265%–650%] versus 152% [130%–277%], P =0.007, and factor VIII 301% [289%–402%] versus 49% [26%–94%], P <0.001). Conclusions: Ischemic stroke in patients with COVID-19 is associated with endotheliopathy and a systemic inflammatory response in patients with vascular risk factors. Further research evaluating endothelial and inflammatory markers in the setting of ischemic stroke and COVID-19 in larger, prospective cohorts is needed to validate the findings.

Objectives: The complexity of endovascular revascularization treatment (ERT) in acute ischemic stroke (IS) and the small number of patients eligible for that treatment justifies the development of Stroke Center networks with interhospital transfer of eligible patients. But it is possible that this approach generate “futile“ transfers (i.e. shift of patients who finally do not receive ET) generating unnecessary costs. Our aim is to analyze the frequency of “futile” transfers, the reasons for rejection for ERT and to identify the possible associated factors. Methods: We analyzed a prospective registry of ERT from a Stroke Network integrated by three hospitals with facilities for ERT for acute stroke patients. These hospitals share a common stroke protocol and have established a weekly rotatory shift with inter-hospital transference to the on-call center for ERT in those patients in whom this therapy is indicated, both primarily, after completing IV thrombolysis or in patients attended in outside hospitals (drip and shift). We analyzed: demographic data, vascular risk factors, stroke severity, frequency of prior intravenous thrombolysis, time from stroke onset and reasons for rejection. Study period: 1/02/2012 to 07/05/2013. Results: ERT protocol was activated in 199 patients, receiving ERT 129 (64.8%). 120 (60.3%) patients required inter-hospital transfer, among them 50 (41%) were not finally treated (futile transfer). These were more often male (74.1% vs. 25.9%, P = 0.04), with no differences in age, vascular risk factors, time-lapse from stroke onset or delay of inter-hospital transfer, baseline NIHSS, baseline ASPECTS or rate of prior intravenous thrombolysis between transferred patients treated with ERT and those non-treated. Reasons for rejection were: clinical improvement (16%), arterial recanalization (24%), clinical deterioration (8%); ASPECTS <7 in the 2nd TC (20%), absence of mismatch (20%); delay in shipment (2%), revocation of consent (1%). Conclusions: 40% of shipments for ERT are “futile”. None of the baseline patient characteristics predict this fact, being arterial recanalization and findings in a second imaging test done in the receiving hospital the main reasons for ERT rejection.
