Active clinical trials for "Ischemic Attack, Transient"

The TASK (Treating Anxiety after StroKe) trial is a feasibility randomized controlled trial. It aims to evaluate the feasibility of i) web-enabled trial procedures, and ii) the TASK intervention in stroke and TIA patients

Interventions to improve health behaviour in patients with resent acute stroke are not well established. This study will evaluate the feasibility and effect of an early initiated counselling intervention targeting smoking, physical activity, and adherence to preventive medication, with regular follow-up sessions, in patients with acute minor stroke or transient ischemic attack who are discharged home.

The investigators will conduct a proof-of-concept randomized controlled trial study to provide preliminary evidence of efficacy of a resistance exercise training program for maintaining white matter health and improving cognitive function in older adults with vascular cognitive impairment, defined as the presence of cognitive impairment combined with cerebral small vessel disease, compared with a stretch and relaxation program.

The objective of the CANOPY trial is to assess the continued safety and effectiveness of the RX Acculink Carotid Stent System under commercial use in subjects at standard risk for adverse events from Carotid Endarterectomy (CEA) enrolled by physicians with a range of carotid stenting experience.

The purpose of this study is to evaluate the safety and efficacy of telcagepant in the treatment of acute migraine in participants with stable vascular disease. Acetaminophen/paracetamol (APAP) will be used as an active comparator in this study. The primary hypothesis of this study is that telcagepant 300 mg is superior to placebo.

This study evaluates the feasibility and effectiveness of an oropharyngeal exercise (O-PE) regimen in treating post-stroke obstructive sleep apnea, as an alternative therapy to continuous positive airway pressure (CPAP). Eligible patients will be randomized (1:1) to treatment using a pre-specified schedule of O-PEs vs. a sham control arm.

Ticagrelor is a reversible and direct-acting oral antagonist of the P2Y12 (Purinergic receptor P2Y, G-protein coupled, 12) receptor for adenosine diphosphate, which provides faster, greater, and more consistent P2Y12 inhibition than Clopidogrel in patients with acute coronary syndrome, irrespective of the genetic variants affecting Clopidogrel metabolism. It is still undefined whether combination therapy of Ticagrelor and Aspirin is more effective than Clopidogrel and aspirin for minor stroke and transient ischemic attack (TIA). The primary purpose of the PRINCE trial is to evaluate the anti-platelet effects of a 3-month regimen of ticagrelor initiated with 180 mg loading dose followed by 90 mg twice/day combined with aspirin 100 mg/day during first 21 days versus a 3-month regimen of clopidogrel initiated with 300 mg loading dose of followed by 75 mg/day combined with aspirin 100 mg/day during first 21 days when initiated within 24 hours of symptom onset in high-risk transient ischemic attack or minor stroke.

The main objective of this study is to compare the incidence of detected atrial fibrillation (AF) in cryptogenic stroke patients by a single lead ECG device with the incidence of detected AF by a 7-Day Holter ECG.

Rationale: To date, anticoagulant therapy in acute stroke has also been limited by excess hemorrhagic events. The oral anticoagulant dabigatran is a novel agent, which has been shown to be associated with much lower intracranial hemorrhage rates. It has been suggested that this agent may provide the superior benefits of anticoagulation in acute stroke, without the concomitant increase in hemorrhage risk associated with heparin/LMWH or warfarin. Study Design: DATAS II is a randomized, open label blinded endpoint trial. Participants (n=300) with TIA or ischemic stroke (NIHSS score <9) will be enrolled within 48 hours of symptom onset from approximately four (4) health care centres across Canada. All participants will have an MRI with DWI lesion volume < 25 ml. Participants will be randomized 1:1 to treatment with dabigatran for 30 days or ASA 81 mg daily (current standard of care). All stroke patients will initially be screened with a non-contrast CT scan of the brain. The first MRI will be performed within 48 hours of symptom onset. Imaging studies will be repeated at day 30. All patients will be assessed clinically at Day 30 and Day 90. Study Aims: Establish the safety of early anticoagulation with the novel oral anticoagulant dabigatran in acute cerebrovascular syndrome patients. Identify the rate of both symptomatic and asymptomatic hemorrhagic transformation (HT) associated with these treatments. Identify predictors of HT associated with acute dabigatran treatment. Hypothesis: The Investigators hypothesize that symptomatic HT rates in dabigatran and ASA treated patients will not be significantly different. Study outcomes: The primary outcome is the rate of symptomatic hemorrhagic transformation (HT), defined as a parenchymal hematoma, which is >30% of the infarcted area on DWI, with substantial space- occupying effect, associated with clinical worsening (≥4 point increase in National Institutes of Health Stroke Scale (NIHSS) score) within 5 weeks of treatment initiation. The major secondary outcome the rate of asymtomatic HT see on day 30 MRI sequence.

The Stroke CTI study is a 3 arm randomized, controlled trial designed to assess the effectiveness of a nurse practitioner (NP) only and a NP and health coach (HC) community transitions intervention (CTI) in reducing secondary stroke risk by helping patients lower their systolic blood pressure.
