Filter by:A pilot trial for assessing early microvascular alterations after aneurysmal subarachnoid hemorrhage using dynamic 18F-FDG PET/CT. The primary endpoint will be the measure of early changes in cerebral glucose uptake reflecting microperfusion.
The purpose of this study is to try to find the best dose of the new drug BAY 2433334 to give to participants and to look at how well BAY 2433334 works on top of antiplatelet therapy in patients following a recent non cardioembolic ischemic stroke which occurs when a blood clot that has not formed in the heart travelled to the brain. BAY 2433334, works by blocking a step of the blood clotting process in our body and thins the blood and is a so called oral FXIa inhibitor.
Acute ischemic stroke (AIS) has the characteristics of high morbidity, high mortality, high disability rate and high recurrence rate. Progressive cerebral infarction (PIS) is a subtype of AIS, accounting for 10% - 40%. Because of the gradual aggravation of neurological deficit symptoms, it has a higher rate of disability and death, which brings heavy mental and economic burden to families, society and the country. The progress of acute cerebral infarction is generally within 6 hours to 1 week after the onset of the disease. At present, it is considered that thrombus prolongation is one of the important pathogenesis of PIS. Heparin can reduce the incidence of post-stroke embolism, but its benefits are offset by the risk of hemorrhage due to the high risk of hemorrhage. The 2013AHA guidelines in the United States do not recommend it as a routine anticoagulant therapy. Therefore, reducing the risk of bleeding is the key to the anticoagulation therapy of PIS. Argatroban is a new thrombin inhibitor. Its mechanism of action is to bind and inactivate thrombin (factor Ⅱ a) directly.Compared with traditional anticoagulants, argatroban not only has the advantages of good anticoagulant effect and rapid onset, but also has high safety. Therefore, this study aims to verify the clinical efficacy of Argatroban in the treatment of PIS in a large population. In this study, 628 patients are expected to be enrolled into the study group. The experimental group and the control group are selected by dynamic random method. Both groups are given standard medical treatment, including routine antiplatelet, blood pressure control, statins to stabilize plaque, etc. The control group is only given standard medical treatment. In the experimental group, Argatroban is used on the basis of standard medical treatment. Both groups are treated for 7 days, and the second-class prevention standard medical treatment is given from the 8th to the 90th day. The main outcome measure is the good prognosis rate at the third month after PIS. The good prognosis was defined as the modified Rankin Scale (mRS) ≤ 3.
This study aims to investigate whether Remote Ischemic Conditioning (RIC) improves rheo-erythrocrine dysfunction in acute ischemic stroke
The purpose of this study is to examine the feasibility and effectiveness of a lower extremity telerehabilitation protocol with aims to improve lower extremity recovery among community-living stroke survivors across Canada.
Randomized controlled phase II trial to test the safety and preliminary efficacy of a dual thrombolytic treatment consisting of a small intravenous (IV) bolus of alteplase followed by IV infusion of mutant pro-urokinase against usual treatment with IV alteplase in patients presenting with ischemic stroke.
The aim of this study is to assess the use of ASPECTS and stroke biomarkers to predict the outcome and cognitive impairment in acute ischemic stroke.
This study will examine the feasibility and effect of a program that combines exercise and feedback from a wearable device on upper limb movement practice and function in individuals with stroke.
Thrombolysis and endovascular thrombectomy are the most efficient treatments for acute ischemic stroke patients in time window. Although sufficient recanalization after thrombectomy is more than 80%, HERMES study indicated that nearly half of the ischemic stroke patients under thrombectomy suffered obvious disability. Artery reocclusion, hemorrhagic transformation, and no-reflow phenomenon are among the most important reasons of poor prognosis of acute ischemic stroke patients. The investigators speculate that a combination of argatroban, edaravone, and glucocorticoid may be helpful in preventing artery reocclusion, hemorrhagic transformation, and no-reflow phenomenon. This study intends to explore the safety, feasibility and efficacy of thrombectomy with sufficient recanalization bridged by intra-arterial cocktail therapy in acute ischemic stroke patients.
Thrombolysis and endovascular thrombectomy are the most efficient treatments for acute ischemic stroke patients in time window. However, sufficient recanalization (mTICI2b-3) can 't be acquired in all patients under thrombectomy. The EXTEND-IA TNK study indicated that tenecteplase before thrombectomy was associated with a higher incidence of reperfusion and better functional outcome than alteplase among patients with ischemic stroke treated within 4.5 hours after symptom onset. This study intends to explore whether a combination of thrombectomy and intra-arterial TNK administration can increase recanalization rate after the first attempt of thrombectomy device pass for ischemic Stroke.
