Filter by:The overall goal of this study is to minimize morbidity due to Atrial Fibrillation (AF). The specific objective is to develop and implement a rational and personalized approach to AF risk estimation that can inform management decisions with ischemic stroke. The investigators propose to develop a clinical AF risk estimation tool in the electronic health record and to test the effectiveness of implementing a clinical AF risk estimation tool into care for use by stroke neurologists during the care of acute ischemic stroke patients at Massachusetts General Hospital. The investigators will evaluate cardiac monitoring utilization calibrated to AF risk by stroke neurologists using a custom electronic health record (EHR) notification module. The investigators hypothesize that cardiac rhythm monitoring utilization will be positively correlated with the predicted risk of AF.
The cerebral collateral circulation refers to the subsidiary network of vascular channels that stabilize cerebral blood flow when principal conduits fail. Collateral status differs among patients with acute ischemic stroke. Relatively sparse attention has been devoted to the role of baseline collateral circulation in patients with acute ischemic stroke who are candidates for revascularization. This study aim to investigate the correlation between baseline collateral circulation and the likelihood of opening of an arterial occlusion, the extent of reperfusion, tissue injury and clinical impairment.
Evaluation of the safety and tolerability of escalating doses of NR1 administered intracerebrally at a single time-point post-injury to subjects with chronic ISS with or without cortical stroke.
Proof-of concept clinical trials have indicated that the sphingosine-1-phosphate receptor modulator fingolimod may be efficacious in attenuating brain inflammation and improving clinical outcomes in patients with acute ischemic stroke as a single therapy beyond 4.5 hours of disease onset, or in combination with alteplase within 4.5 hours of disease onset. This study aim to determine whether fingolimod enhance the action of endovascular treatment for acute ischemic stroke
It is known that atrial fibrillation after stroke significantly increases the risk of stroke or systemic embolism. Accordingly, efforts have been made to detect hidden atrial fibrillation and apply treatment using anticoagulants instead of antiplatelet agents. The conventional method used to screen for atrial fibrillation in stroke patients who did not have atrial fibrillation at first admission is 24-hour Holter monitoring. This study will compare the detection rate of atrial fibrillation with discontinuous ECG monitoring three times a day and 72 hours of single-lead ECG patch monitoring compared with the conventional Holter test.
Previous study showed that the proportions of hemorrhagic Infarction after intravenous thrombolysis were 24.2% and 32.5% in the control group and the alteplase group, and most of them were asymptomatic. Hemorrhagic Infarction was a part of the natural progression after acute ischemic stroke. Previous study have shown no significant relationship between hemorrhagic Infarction and poor outcome in acute ischemic stroke (AIS) patients. In this study, a randomized controlled trial will be conducted to explore the efficacy and safety of early antiplatelet therapy after hemorrhagic infarction in acute ischemic stroke treated with intravenous thrombolysis.
This is a pilot, monocentric clinical investigation to evaluate the suitability of StrokeWave in distinguishing haemorragic from ischaemic strokes. The StrokeWave is a microwave device which employs a novel technique to generate images by processing very low power (<1mW) microwaves. The trial design has been developed in order not to interfere with thw standard diagnostic approach used for the hyperacute stroke patients, nor to modify the usual standard timing of the routine assessment.
This observational study as an objective of characterizing the population of patients treated within the neurovascular unit of the Pierre Wertheimer hospital (Hospices Civils de Lyon) in order to determine their phenotype (age, sex, risk factors, etc.) and its evolution over time. It also aims to assess the management of ischemic stroke (IS) in the neurovascular unit of Pierre Wertheimer Hospital. We will assess in particular the pre-hospital and hospital care times, the type of medical care (thrombolysis and / or thrombectomy) as well as the efficiency of this care (effective recanalization, outcome of patient, etc.).
Stroke is the first cause of death among Spanish women and main cause of disability. Reperfusion therapies of the occluded artery remain the only useful approach in acute ischemic stroke. However, the efficacy of these strategies is highly time-dependent and due to the need of neuroimaging (CT or MRI) to differentiate between ischemic and hemorrhagic stroke, impossible to be performed at the pre-hospital level. The investigators aim to set-up a point of-care (POC) device to validate a biomarker panel differentiating ischemic and hemorrhagic stroke at the pre-hospital level using a blood sample and to validate a second biomarker panel for the early identification of patients with large vessel occlusions (LVO), which are candidates for mechanical thrombectomy. For that, the investigators will recruit a 300 patients' cohort with pre-hospital blood samples using available POCs for each of those markers.
This study is aimed to elucidate the factors affecting the remodeling process of arteriolosclerosis under current practice recommendations. Such knowledge may improve the understanding of cerebral small vessel disease (cSVD) mechanism, define pharmacological therapy and suggest treatment target.
