Filter by:The hypothesis of this study is that "the poor metabolizer or intermediate metabolizer of the cytochrome P450 2C19 genotype in patients with acute ischemic stroke is associated with increased risk of composite cardiovascular events (recurrent stroke, myocardial infarction, cardiovascular death) compared to those who of extensive metabolizer of the cytochrome P450 2C19 genotype".
This study is designed to compare the safety, performance and efficacy of blood clot (thrombus) removal in subjects presenting with acute ischemic stroke with the NeVa versus the Solitaire stent retrievers.
The current study has the potential to improve rehabilitation during the subacute phase of a stroke, aiming to reduce the individual's disabilities and risk of falling, enhance health promoting physical activity and independence in ADL.
Use of intravenous(IV) thrombolysis and intra-arterial(IA) recanalization treatment has been rapidly increasing, However, despite of the treatment, recanalization rates are 22.6 - 70% and only 30-50% of patients show meaningful clinical improvements. Mechanisms of futile recanalization may include 1) large ischemic core, 2) poor collateral, and 3) presence of comorbidity. In this regards, developing selection criteria using acute stroke imaging and comorbidity is warranted. The investigators will recruit the consecutive acute stroke patients who received IV thrombolysis and/or IA recanalization treatment. This study will perform with prospective design to develop CT-based clot, core and collateral scores and a comorbidity index for selecting stroke patients who are at high risks by the treatment. The investigators will firstly establish the CT-based scores and comorbidity index using a pre-existing cohort database. Using these CT-based and comorbidity index, the investigators will validate them in a multi-center prospectively cohort.
This proposal is a prospective, single-center, dose-escalation safety, tolerability, feasibility and potential efficacy study of transcranial direct current stimulation (tDCS) in acute stroke patients with substantial salvageable penumbra due to a large vessel occlusion before and after endovascular therapy.
The main objective of the study will be to investigate whether treatment with non-invasive vagus nerve stimulation (nVNS) on top of best medical practice in acute ischemic stroke patients results in less infarct growth in the penumbra and smaller infarct volumes compared with those of patients not treated with nVNS. The study will be a prospective randomized clinical trial with blinded outcome assessment (PROBE design). 150 patients will be randomized to nVNS with the gammaCore Sapphire™ device on top of best medical practice versus best medical practice alone (including intravenous thrombolysis and/or thrombectomy if indicated). If patients are randomized to nVNS, two stimulations of two minutes each will be applied in the neck every 15 minutes in the first 3 hours. Thereafter two stimulations will be applied every 8 hours over the next 5 days or until discharge, whichever occurs first. The stimulation side in the neck will be the radiological side of the stroke. The primary endpoint will be the final infarct volume on MRI scan on day 5 of patients treated with nVNS compared with those of patients not treated with VNS.
In the present prospective, multicentric, randomized, double-blind, parallel, saline-controlled phase II clinical study; the investigators plan to evaluate the efficacy of sovateltide (IRL-1620 or PMZ-1620) therapy along with standard supportive care in patients of acute ischemic stroke.
This was a prospective, multicentric, randomized, double blind, parallel, saline controlled Phase II clinical study to compare the safety and efficacy of PMZ-1620 (INN: Sovateltide) therapy along with standard supportive care in patients of acute ischemic stroke.
Interventionnal Study to investigate the accuracy of our clinical based algorithm performed by using a visioconference device to assess the eligibility of acute recanalisation treatment (intraveinous thrombolysis (IVT) and/or mechanical thrombectomie (TM). Clinical identification of type of treatment is needed is pre-hospital triage of these patients.
This innovative study will address scientific and clinical areas relatively unexplored in chronic stroke that could lead to greater recovery of walking. Ischemic Conditioning (IC) is a non-invasive, simple procedure that improves motor function, exercise performance and cardiovascular function in healthy controls, but it has never been applied to the stroke population. We postulate that IC enhances the recruitment of motoneurons and results in positive neural adaptations, improves vascular endothelial function and peripheral blood flow, and together these improvements result in an increased capacity to exercise and faster walking speed. Future studies will examine the effects of IC and traditional therapy at different time points of recovery post stroke, durability of IC, molecular mechanisms of neural and cardiovascular adaptation and the efficacy compared with other adjuncts.
