Filter by:The purpose of this study is to examine the role of Hyperbaric Oxygen Therapy (HBOT) in improving neurological function in patients who are 6 to 36 months post ischemic stroke.
Confirm central blood pressure reduction effect of Fimasartan, Valsartan and Atenolol and compare correlation with the measured peripheral (central blood pressure, pulse wave velocity, and flow-mediated dilation) and cerebral blood flow factors (transcranial doppler findings, cerebral blood flow volume) in acute ischemic stroke patients with hypertension.
This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care. In the intervention group TNK-tPA is given as a single, intravenous bolus (0.25mg/Kg) immediately upon randomization. Maximum dose 50mg. The control group will receive antiplatelet agent(s) as decided by the treating physician. Antiplatelet agent(s) choice will be at the treating physician's discretion. TEMPO-2 Coordinating Centre is located in Calgary, AB, Canada. There will be approximately 50 sites participating worldwide. Dr. Shelagh Coutts is the Principal Investigator.
Anticoagulants are generally recognized as a necessary therapy to prevent the recurrence of ischemic stroke in patients with non-valvular atrial fibrillation (NVAF), but in some patients they also cause bleedings, particularly intracranial hemorrhage. One of the independent predictors of intracerebral hemorrhage is the presence of cerebral microbleeds (CMBs); a high incidence of intracerebral hemorrhage is reported in patients with multiple CMBs. Recent study suggested that patients who had CMBs at baseline developed more new CMBs after 2 years (26%), compared with patients (12%) who did not have CMBs at baseline. However, there has been no study on the progression of CMBs in patients receiving so-called novel oral anticoagulants (NOACs). This study tests the hypothesis that the incidence of hemorrhagic stroke is lower in patients receiving NOACs (dabigatran, rivaroxaban, apixaban, and edoxaban) than in those receiving warfarin, and this difference reflects the difference in the effects of warfarin and NOACs on the progression of CMBs. Towards this goal, we enroll 200 patients with at least one CMB detected by 1.5 T MRI (T2*WI) at baseline, who treated with NOACs or warfarin for 12 months. Primary endpoint is the proportion of subjects with an increased number of CMBs at Month 12 of treatment with NOACs or warfarin. If the results of this study support the efficacy of NOACs in preventing increase of CMBs, this would be of great interest to domestic and overseas clinicians, in view of the potential therapeutic impact, including that for primary prevention of ischemic stroke.
Patients who suffer an ischemic stroke in the occipital lobe often experience Visual Field defects. Visual Field defects are negatively correlated to falling, institutionalisation, rehabilitation outcome and quality of life. Patients are often not properly examined and seldom receive rehabilitation. NOR-OCCIP aims to evaluate the Natural history of Visual Field defects after occipital infarction and to determine whether rehabilitation is effective.
The primary goal of this project is to carry out a trial comparing pre-hospital diagnosis and treatment of patients with stroke symptoms using a Mobile Stroke Unit (MSU) with subsequent transfer to a Comprehensive Stroke Center (CSC) Emergency Department (ED) for further management, to standard pre-hospital triage and transport by Emergency Medical Services (EMS) to a CSC ED for evaluation and treatment (Standard Management-SM).
This will be a randomized double blind placebo-controlled pilot study using a repeated measures design in which participants with acute ischemic stroke and upper extremity weakness are randomized to either drug or placebo
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
