Background and Purpose— Limited data exist concerning obesity survival in patients after acute stroke. The objective of this study was to investigate the association between with first-ever Methods— Patients were prospectively investigated based on a standard diagnostic protocol over period 16 years. Evaluation performed admission, at 7 days, 1, 3, 6 months discharge, yearly thereafter for up 10 years divided into 3 groups according body mass index (BMI): normal weight (<25 kg/m 2 ),...
To develop and validate a simple, integer-based score to predict functional outcome in acute ischemic stroke (AIS) using variables readily available after emergency room admission.Logistic regression was performed the derivation cohort of previously independent patients with AIS (Acute Stroke Registry Analysis Lausanne [ASTRAL]) identify predictors unfavorable (3-month modified Rankin Scale >2). An point-scoring system for each covariate fitted multivariate model generated by their...
Recent case-series of small size implied a pathophysiological association between coronavirus disease 2019 (COVID-19) and severe large-vessel acute ischemic stroke. Given that strokes are typically associated with poor prognosis can be very efficiently treated recanalization techniques, confirmation this putative is urgently warranted in large representative patient cohort to alert stroke clinicians, inform pre- in-hospital pathways. We pooled all consecutive patients hospitalized...
The NAVIGATE ESUS randomized clinical trial found that 15 mg of rivaroxaban per day does not reduce stroke compared with aspirin in patients embolic undetermined source (ESUS); however, it substantially reduces risk atrial fibrillation (AF).OBJECTIVE To analyze whether is associated a reduction recurrent among who have an increased AF.DESIGN, SETTING, AND PARTICIPANTS Participants were stratified by predictors AF, including left diameter, frequency premature contractions, and HAVOC score,...
The coronavirus disease 2019 (COVID-19) pandemic has been placing an overwhelming burden on health systems, thus threatening their ability to operate effectively for acute conditions in which treatments are highly time sensitive, such as cerebrovascular disorders and myocardial infarction. As part of effort reduce the consequences this outbreak service delivery stroke patients, European Stroke Organisation undertaken a survey aimed at collecting information provision care during...
The purpose of the European Stroke Organisation–Karolinska Update Conference is to provide updates on recent stroke therapy research and give an opportunity for participants discuss how these results may be implemented into clinical routine. meeting started 22 years ago as Karolinska Update, but since 2014 it a joint conference with Organisation. Importantly, provides platform discussion Organisation guidelines process recommendations committee specific topics. By this, adds direct influence...
To measure the global impact of COVID-19 pandemic on volumes IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at height (March 1 to June 30, 2020) compared with 2 control 4-month periods.We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, 457 centers. Diagnoses were identified by their ICD-10 codes or classifications in databases.There 91,373 admissions immediately before 80,894 during months, representing an...
The effect of early as compared with later initiation direct oral anticoagulants (DOACs) in persons atrial fibrillation who have had an acute ischemic stroke is unclear.We performed investigator-initiated, open-label trial at 103 sites 15 countries. Participants were randomly assigned a 1:1 ratio to anticoagulation (within 48 hours after minor or moderate on day 6 7 major stroke) (day 3 4 stroke, 12, 13, 14 stroke). Assessors unaware the trial-group assignments. primary outcome was composite...
The management of patients with stroke is often multidisciplinary, involving various specialties and healthcare professionals. Given the common shared risk factors for cardiovascular disease, input may also be required from teams, as well patient caregivers next-of-kin. Ultimately, central to all this, requiring a coordinated uniform approach priorities post-stroke management, which can consistently implemented by different multidisciplinary professionals, part 'journey' or 'patient...
One in six ischaemic stroke patients has an embolic of undetermined source (ESUS), defined as a with unclear aetiology despite recommended diagnostic evaluation. The overall cardiovascular risk ESUS is high and it important to optimize strategies prevent recurrent other events. aim clinicians when confronted patient not only but also any medical condition identify the actual cause amongst list potential differential diagnoses, order secondary prevention. However, specifically ESUS, this may...
Direct oral anticoagulants (DOACs) reduce the rate of thromboembolism in patients with atrial fibrillation but benefits and risks survivors intracerebral haemorrhage are uncertain. We aimed to determine whether DOACs risk ischaemic stroke without substantially increasing recurrent haemorrhage. PRESTIGE-AF is a multicentre, open-label, randomised, phase 3 trial conducted at 75 hospitals six European countries. Eligible were aged 18 years or older spontaneous haemorrhage, fibrillation, an...
Stroke registries are valuable tools for obtaining information about stroke epidemiology and management. The Acute STroke Registry Analysis of Lausanne (ASTRAL) prospectively collects epidemiological, clinical, laboratory multimodal brain imaging data acute ischemic patients in the Centre Hospitalier Universitaire Vaudois (CHUV). Here, we provide design methods used to create ASTRAL present baseline our (2003 2008).All consecutive admitted CHUV between January 1, 2003 December 31, 2008 with...
CHADS2 and CHA2DS2-VASc scores are used to assess stroke risk in patients with atrial fibrillation (AF). We investigated whether these associated outcome non-AF patients.Consecutive acute first-ever ischemic but without AF were classified into subgroups according prestroke followed up for 5 years. The end points death, recurrence, a composite of major cardiovascular events.Among 1,756 (aged 67.2 ± 12.3 years, 68.2% males), there 258 (14.7%), 617 (35.3%), 878 (50.0%) low, intermediate, high...
A new clinical construct termed embolic stroke of undetermined source (ESUS) was recently introduced, but no such population has been described yet. Our aim is to provide a detailed descriptive analysis an ESUS derived from large prospective ischemic registry using the proposed diagnostic criteria.The criteria by Cryptogenic Stroke/ESUS International Working Group were applied Athens Stroke Registry identify all patients. defined as radiologically confirmed nonlacunar brain infarct in...
Several data indicate that migraine, especially migraine with aura, is associated an increased risk of ischemic stroke and other vascular events. Of concern whether the in migraineurs magnified by use hormonal contraceptives. As prevalence high women reproductive age, it common to face issue contraceptive clinical practice. In this document, we systematically reviewed about association between use. Thereafter a consensus procedure among international experts was done develop statements...
