Filter by:The clinical and radiological data of patients with an acute ischemic stroke treated with intravenous thrombolysis (IVT) or intraarterial thrombolysis (IAT) in a Swiss stroke unit are assessed in a Swiss Multicenter Thrombolysis Registry. Like in clinical routine, a clinical evaluation takes place in a 3-months follow-up. Furthermore quality of life is assessed with a standardized questionnaire. The aim of the registry is to compare the safety and efficacy of IVT and IAT in patients with acute ischemic stroke. The registry also helps to improve in-hospital-management of stroke patients.
The primary study objective is to assess the feasibility of using the MindFrame System to safely and effectively restore blood flow in a thrombotic neurovascular occlusion in patients experiencing an ischemic stroke.
1. Circulating bone marrow and blood vessel precursors home in to sites of ischemia and aid regeneration of injured tissue 2. Increasing the number of circulating precursors will improve in regeneration of damaged brain following ischemic stroke.
This study involves treating patients that have suffered an acute ischemic stroke with the medication donepezil (Aricept ®). The hypothesis is that taking donepezil (FDA-approved for the treatment of Alzheimer's Disease) for the first 90 days following a stroke enhances recovery.
The purpose of this study is to determine the safety, tolerability, and to explore the possible benefit of extended-release niacin (Niaspan®) in attempting to improve the recovery of patients after ischemic stroke.
Iron overload has been associated with greater brain injury in ischemia/reperfusion experimental stroke models and ischemic stroke patients, especially in those treated with thrombolytic treatment. Deferoxamine administration, an iron chelator, offers a neuroprotective action in ischemia/reperfusion animal models. Primary objective: To evaluate the security and tolerability of deferoxamine endovenous treatment in acute ischemic stroke patients treated with iv. tPA. Secondary objectives: To study pharmacokinetics of deferoxamine given by endovenous bolus (10 mg/Kg) followed by 72-hour continuous intravenous infusion (20, 40 o 60 mg/Kg). To evaluate the deferoxamine effect in clinical outcome, infarct volume and hemorrhagic transformation and brain edema development. Methodology: Double-blind, randomized, placebo controlled, dose-finding phase II clinical trial. Study stages: 1st: bolus+20 mg/Kg/day vs. Placebo (n=15:5); 2nd: bolus+40 mg/Kg/day vs. Placebo (n=15:5); 3rd: bolus+60 mg/Kg/day vs placebo (n=15:5). These doses will be increased according to security results of the previous stage. Patients will be continuously monitored in stroke units. Laboratory parameters will be measured at baseline, 24h, 72h and 30 days to evaluate adverse events related to the drug. Serum deferoxamine and feroxamine concentrations will be measured along time after the injection in a subgroup of patients to the pharmacokinetics study. CT scan will be performed at 24-36h to assess hemorrhagic transformation and brain edema. The NIH Stroke Scale will be evaluated during hospitalization, and the Rankin score at discharge and 3 months. If deferoxamine demonstrate to be secure and well tolerated treatment in acute stroke patients, it may be a new therapy option to lower the brain injury after ischemia and reperfusion.
To compare the effect of losartan vs amlodipine-based antihypertensive therapy on atherosclerotic inflammatory markers and cerebrovascular regulation in Ischemic stroke patients.
Our overall goal is to advance the state of functional brain imaging in aphasia, and then to apply the method to an intensive, imitation-based treatment for non-fluent aphasia.
This is a prospective study including acute ischemic stroke patients aged 18 to 90. Multidetector raw CT is performed in acute ischemic stroke patients. Heart, neck vessels and brain arteries are studied during the same acquisition. Results are compared with the standard methods including transesophageal echocardiography (TEE), Doppler ultrasound (DUS) and MR angiography (MRA) of neck vessels. The main criteria is the ability of CT to classify the stroke etiology correctly according to the TOAST classification in comparison with the standard methods.
The specific objectives of this thesis are in a cohort of patients with an acute ischemic stroke, 1. To establish the degree of coronary arteriosclerosis. 2. To describe left ventricular systolic and diastolic function in relation to changes of NT-proBNP.
