The aim of this study is to determine the diagnostic yield of continuous 7-day Holter ECG for detecting covert paroxysmal atrial fibrillation in patients with recent embolic stroke or transient ischemic attack (TIA) of undetermined cause after completion of a standard clinical work up including an initial 24-hour Holter monitoring.
In a double blind placebo-controlled cross-over study the effect of tadalafil on blood flow velocity in the large arteries of the brain, cortical brain oxygenation, peripheral endothelial function, and endothelial biomarkers will be tested in patients with lacunar stroke caused by cerebral small vessel disease.
Ischemic stroke is the leading cause of acquired disability among adults, and one of the main causes of death. In Switzerland, the approved time window for stroke treatment with intravenous thrombolysis after symptom onset is 4.5 h. Even within the 4.5 h time-window, however, the benefit of treatment strongly decreases as time passes. Moreover, only around 10% patients receive thrombolytic treatment, since patients with stroke arrive too late to the hospital (prehospital delay). Despite efforts to educate the community on the symptom of stroke, prehospital delay did not decrease over time, and the reasons remain incompletely understood. Prehospital delay reduces the proportion of patients with ischemic stroke treated with thrombolysis, and reduces the odds of favorable outcome among the minority treated with thrombolysis. This prospective cohort study aims at understanding the causes of prehospital delay among patients with acute ischemic stroke. Trained study-nurses will interview, at the bedside, patients and proxies along a standardized questionnaire on prehospital delay. Avoiding modificables causes of prehospital delay may increase the thrombolysis rate and improve outcomes after stroke.
Physical activity level is an important determinant of quality of life in persons post-stroke. There is a lack of knowledge regarding the effects of aerobic training on physical activity levels in subjects post-stroke. Therefore, the primary objective will be to investigate the effects of aerobic treadmill training on physical activity levels and sedentary behavior in subjects post-stroke. The secondary aim will be to investigate the effects of the training on cardiorespiratory fitness, endurance, depression, mobility, quality of life, and participation. A randomized controlled trial with blinded assessment will assign eligible participants to either: 1) aerobic treadmill training (experimental group, at 60-80% of heart rate reserve), or 2) overground walking (control group, below 40% of heart rate reserve). Both groups will receive 40-minute training sessions three times/week over 12-weeks, in groups of 2-4 participants, by a trained physiotherapist. Primary outcomes: physical activity levels and sedentary behavior (Multisensor SenseWear Mini® and Human Activity Profile). Secondary outcomes: cardiorespiratory fitness (peak oxygen uptake (VO2peak) and ventilatory threshold), endurance, depression, mobility, quality of life, and participation. The effects of the trainings will be analyzed from the collected data and intention-to-treat analysis. Between-groups differences will be measured by two-way ANOVA with repeated measures considering the baseline, post-training, and a 4-week follow-up. The results of this trial will likely provide valuable new information about the effects of aerobic treadmill training in improving physical activity levels and sedentary behavior, through changes in cardiorespiratory fitness, for individuals following stroke.
This study is a 12-month, double-blind, randomized, placebo-controlled trial. The purpose of this study is to determine whether ginseng is effective in the prevention of atherosclerosis and subsequent ischemic stroke. High-risk patients with severe atherosclerosis in the major intracranial arteries and extracranial carotid artery were enrolled.
To evaluate the hypothesis that direct transfer to an Endovascular Stroke Center, compared to transfer to the closest Local Stroke Center, offers a better outcome in the distribution of the modified Rankin Scale scores at 90 days in acute ischemic stroke patients with clinically suspected Large Vessel Occlusion identified by Emergency Medical Services (EMS).
Stroke is one of the leading causes of death and disability in the UK and currently costs the country £7bn per year. There is an overwhelming need to accurately and rapidly triage patients to allow best use of finite NHS specialist resources for the treatment of stroke. A simple blood test of substances (the purines) that result from cellular metabolism and are produced in excess when brain cells are starved of oxygen and glucose (as occurs during a stroke) is proposed. The sensors designed by the investigators are used to measure blood purines during a procedure in which blood flow to the brain is reduced to allow surgical interventions on the major arteries that supply the brain. Previous studies by the investigators have shown that as soon as blood flow to the brain is reduced, purines are produced within minutes and are detectable in systemic arterial blood. The current project will now compare the levels of purines in the blood of stroke patients and controls. The purines will be measured on admission to hospital and 24 hours later. The occurrence and magnitude of a stroke will be determined by an MRI scan given between 24 and 72hrs after admission. This study will establish whether purines are elevated in the blood of stroke patients on admission to hospital compared to healthy controls, and whether this correlates with the size of the stroke and damage to the brain.
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
The Programme is focused on adult patients of any gender and age more than 18 y.o., with the next conditions: 1. Acute cerebrovascular events (ACE, ischemic stroke or intracerebral hemorrhage - specialty neurology) 2. Acute myocardial infarction (AMI, specialty cardiology) 3. Patients after total hip replacement (THR, specialty orthopaedia) The program is performed in the in-patient and out-patient rehabilitation departments in 13 regions of the Russian Federation (total 244 departments).
