Filter by:The primary objective of the study is to compare the effect of 90-day treatment with ticagrelor (180 mg [two 90 mg tablets] loading dose on Day 1 followed by 90 mg twice daily maintenance dose for the remainder of the study) vs acetylsalicylic acid (ASA)-aspirin (300 mg [three 100 mg tablets] loading dose on Day 1 followed by 100 mg once daily maintenance dose for the remainder of the study) for the prevention of major vascular events (composite of stroke, myocardial infarction [MI], and death) in patients with acute ischaemic stroke or transient ischaemic attack (TIA).
Our study aimed to examine a possible association between Restless legs syndrome and cerebrovascular disease, by examining patients during hospitalization for acute stroke or transient ischemic attack, in a matched case-control design.
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.
This study is to determine the clinical and neuroimaging characteristics of Transient Ischemic Attacks in Korean populations.
Stroke is the leading cause of disability, third leading cause of death, and one of the most resource-intensive diseases among Americans. African-Americans (AA) have a stroke rate nearly double that of Euro-Americans (EA), and AA who experience a first-ever stroke are younger, have greater stroke disability, more post-stroke complications, and slower recovery compared to EA.
Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.
Objective: Demonstrate the safety of early use of dabigatran following TIA/minor stroke. Background: Although aggressive antithrombotic therapy has been shown to reduce the number of new ischemic events following stroke/TIA, this has always been offset by an increase in the risk of hemorrhagic transformation. Dabigatran is much safer than previously tested antithrombotic agents, with respect to intracranial bleeding and therefore offers a unique treatment opportunity in these high-risk patients. TIA/minor stroke represent the largest group of cerebrovascular disease patients. A short-term intervention such as 30 days of dabigatran treatment has the potential for a very large impact from the population health perspective, given the number of patients who may be treated if a benefit can be demonstrated. Study design: This is an open label, single arm study. Patients with TIA/minor stroke (National Institutes of Health Stroke Scale (NIHSS) score </=3) who can be treated within 24 hours of symptom onset will be eligible. All patients will be treated with dabigatran for 30 days. The dose of dabigatran will be determined by age and renal function (patients >80 years old and/or with GFR 30-50 ml/min will received 110 mg bid, and all other patients will receive 150 mg BID).The primary endpoint is symptomatic hemorrhagic transformation. Patients (n=50) with TIA/minor stroke, defined as having a National Institutes of Health Stroke Scale Score of </=3, will undergo an MRI, including diffusion-weighted imaging (DWI), as well as gradient recall echo (GRE) sequences, which will be used to assess for hemorrhagic transformation. Patients will have a repeat MRI examination at 7 and 30 days to assess for hemorrhagic transformation and new lesion development. The primary endpoint of of phase I is symptomatic hemorrhagic transformation, defined as a parenchymal hematoma on the day 7 MRI scan (GRE sequence), associated with clinical worsening (>/=4 point increase in National Institutes of Health Stroke Scale (NIHSS) score). If dabigatran can be used safely in this population, a second phase aimed at demonstrating the rate of new ischemic lesion development following TIA can be reduced with aggressive antithrombotic therapy. A randomized open-label, blinded endpoint evaluation design will be employed. The investigators hypothesize that dabigatran therapy administered within 24 hours of symptom onset will reduce the rate of new ischemic lesions, relative to standard care, one week and 30 days after onset.
Patient suffering a Transient Ischemic Attack (TIA) or stroke are subsequently at high risk of a new stroke, however, poor adherence to secondary prevention medications occurs frequently within this patient group. The purpose of this study is to evaluate whether a complex tailored pharmacist intervention will lead to increased adherence to secondary stroke prevention medications and less new stroke events when compared to a usual care group. Interventions focus on motivational interviewing, medication review and telephone follow up.
Patients suffering from symptomatic carotid artery stenosis, transient ischemic attacks (TIAs), amaurosis fugax or stroke receive either Revacept (single dose) plus antiplatelet monotherapy or monotherapy alone. Patients receive a single dose of trial medication by intravenous infusion for 20 minutes. Patients are followed up one and three days after treatment, at 3 months and by a telephone interview at 12 months.
A natural form of vitamin E called tocotrienol (TCT), found in many common foods such as barley, decreases stroke size in animal models. Vitamin E has blood-thinning properties and lowers cholesterol, which make it a potential therapy for stroke prevention, though these effects are less well characterized for TCT. We plan to conduct two trials (I & IIA) to determine the effects of orally supplemented TCT on platelet function and cholesterol.
