Filter by:Stroke is a cruel disease that disproportionately kills and disables African-Americans, Latinos, Chinese-Americans and Korean-Americans; seniors with high blood pressure are at particularly high risk. There is a higher incidence of hemorrhagic stroke in African Americans, Latinos, and Chinese Americans relative to non-Latino whites. Asian-Americans have up to 1.4 higher relative risk of stroke death compared to U.S. non-Latino whites. A critical need therefore exists for a sustainable and scalable mechanism to disseminate culturally-tailored stroke knowledge/prevention education in community-based settings where large numbers of these high-risk ethnic minority older adult groups are regularly served, such as in federally funded Multipurpose Senior Centers (MPCs) that exist across the nation (16 of which are in Los Angeles alone). The overall objective of the proposed study is to develop and test the implementation of a training program for case managers at senior centers to implement a stoke knowledge/prevention education program among four high-risk ethnic minority older adult groups--Korean-American, Chinese-American, African-American, Latinos. We propose to develop a culturally-tailored case manager training curriculum, implement the training at 4 community-based sites, and evaluate the training model using a randomized wait-list controlled trial (n=244) testing the hypothesis that training case managers will decrease older adult participants' stroke risk in a sustainable fashion through increasing their preventative behavior (i.e. increasing their physical activity--mean steps/day--at 1 and 3 months). Findings will inform similar community-academic partnership efforts around stroke and other disease-specific prevention research/interventions; they will also determine next steps in terms of whether this case manager-centric model can be scaled up and deployed in other community-based settings.
The purpose of this study is to improve secondary prevention of ischemic stroke patients by 1. Estimating prevalence and the prognostic significance of frequent premature atrial complexes in ischemic stroke patients in relation to death, recurrent stroke and atrial fibrillation. 2. Characterize ischemic stroke patients by 1. Echocardiographic characteristics 2. Biochemical markers 3. Plaque composition in the carotid arteries - in order to improve risk stratification.
This is a double-blind parallel arm randomized trial aimed to assess efficacy and safety of intravenous Tenecteplase compared to intravenous Alteplase in eligible patients who present with symptoms of acute ischemic stroke within 3 to 4.5 hours from onset.
The purpose of this study is to evaluate the safety and tolerability of high-dose minocycline in the patient population undergoing carotid revascularization procedures, namely carotid endarterectomy (CEA) and carotid artery stenting (CAS). Establishment of safety will facilitate proceeding to a phase II trial. During this trial, patients undergoing carotid revascularization procedures will receive high doses of minocycline with the following schedule (based on previous trials): - Day prior to procedure: 800mg orally (p.o), 700mg p.o. - Day of procedure: 600mg intravenously( i.v.), 500mg p.o. - Day after procedure: 400mg p.o., 400mg p.o. The levels of the drug in the plasma, standard blood tests (complete blood count, creatinine, liver function tests) as well as markers of neuronal injury (Neuron specific enolase, protein- S100b) and inflammation (C-reactive protein) will also be monitored. The patients will be monitored closely for the development of side effects from minocycline. MRI imaging will be used to follow the development of small strokes as a result of the revascularization procedures and their resolution. The patients of this study, all receiving peri-operative minocycline, will be compared with historical controls with regards to development of small strokes and persistent of these strokes on subsequent MRI imaging.
This trial aims to test that intra-arterial injection of autologous bone marrow mononuclear cells in acute ischemic stroke patients is safe and improves neurological outcomes.
The investigators goal is to improve the outcome of patients with acute stroke by inducing mild cerebral hypothermia through surface cooling at the cervical and shoulder regions using EMCOOLS Brain.Pads®. For this project, the investigators can build further on their research group's experience with hypothermia in animal models and invasive cooling in stroke patients. The COOL program will prospectively evaluate safety, feasibility, patient acceptance and efficacy of mild cerebral hypothermia using EMCOOLS Brain.Pads® in a large cohort of patients presenting with acute stroke at the Emergency Department of the Universitair Ziekenhuis Brussel. The application of EMCOOLS Brain.Pads® will be compared to routine clinical practice in a randomized controlled trial. If proven to be safe, feasible, well-tolerated and efficacious in the inhospital setting, future use in prehospital acute stroke care will be incorporated with telemedicine support, as part of the Prehospital Stroke Study at the Universitair ziekenhuis Brussel (PreSSUB).
The purpose of this study is to explore the pharmacological mechanism of Danhong injection in the treatment of acute ischemic stroke.
Specific cardiovascular diseases, such as stroke and heart attack, have been shown to vary by ethnic group. However, less is known about differences between ethnic groups and a wider range of cardiovascular diseases. This study will examine differences between ethnic groups (White, Black, South Asian and Mixed/Other) and first lifetime presentation of twelve different cardiovascular diseases. This information may help to predict the onset of cardiovascular diseases and inform disease prevention strategies. The hypothesis is that different ethnic groups have differing associations with the range of cardiovascular diseases studied.
To assess if information about aortic calcification obtained from routine preoperative ultra low-dose chest CT lowers the postoperative stroke rate in patients undergoing heart surgery by optimizing surgical strategy compared to the normal work-up with a conventional chest X-ray.
Stroke is one of main causes of death and impairment worldwide. Objective of this study is to analyze serum High Sensitivity C-Reactive Protein in acute phase stroke in patients attended at Petróleos Mexicanos Hospital Central Sur de Alta Especialidad and to correlate with stroke extension and clinical features.
