Filter by:To date, the investigators have successfully employed a radiotracer (18F-sodium fluoride) as a marker of necrotic inflammation in human atherosclerosis. The investigators aim to further the mechanistic understanding of atherothrombosis by studying the activation of glycoprotein IIb/IIIa receptors in cardiovascular thrombus using the novel platelet radiotracer (18F-GP1). Binding of 18F-GP1 to activated platelets in venous and arterial thrombi has already been demonstrated in pre-clinical studies and a phase 1 trial in man. If successful, this study would define the role of the glycoprotein IIb/IIIa receptor within in vivo thrombosis across a range of cardiovascular diseases.
Aerobic conditioning is very important after stroke as it may reduce the risk of subsequent stroke and overall mortality. High-intensity interval training (HIIT), in which aerobic training workload is varied between lower and higher intensity bouts within a training session, is known to be effective for maximizing aerobic capacity in healthy individuals and those with cardiac disease. HIIT has not been studied extensively in adults with stroke, but it could be an efficient way to maximize aerobic capacity in this population. Furthermore, using heart rate response to establish training intensity may lead to underestimation of target intensity after stroke because blood pressure medications may blunt the heart rate response. Ventilatory threshold is an alternate method of establishing training intensity and is derived independently of heart rate response. The investigators hypothesized that a 10-week program of treadmill HIIT with intensity based on ventilatory threshold would be feasible in adults at least 6 months post-stroke, and would increase aerobic capacity.
Creatine monohydrate is important for sustaining phosphocreatine stores in tissues such as muscle and brain. Phosphocreatine is an important source of energy in these tissues. Supplementation with creatine monohydrate is effective in healthy and clinical populations for improving muscle and brain function. The purpose of our study is to determined whether creatine supplementation is effective during resistance training for improving muscle and brain function in people recovering from stroke.
The purpose of the project is to investigate specific markers in blood samples from patients with stroke (ischemic or hemorrhagic). This could hopefully help in the early diagnostic to separate patients with ischemic stroke from those with hemorrhagic stroke as treatment are different and patients need to come quickly to the correct treatment site.
Early mobilization was thought to be effective in patients with acute ischemic stroke. As the essential component of stroke unit care, early mobilization has already been part of routine clinical practice. However, it is uncertain that which and when medical service focusing on functional recovery should be delivered after the emergency interventions for stroke. Besides, the optimal time window, for delivering early mobilization after acute ischemic stroke, has not been verified with strong evidence.
Researchers are trying to determine if subjects with lack of access to healthy food and a long term health problem, are helped by a weekly box of healthy groceries and nutrition education.
Stroke is the 4th leading cause of mortality in Hong Kong. It also carries considerable socioeconomical consequences due to disability. Ischemic stroke can be classified by the TOAST classification, which includes large artery atherosclerosis, cardioembolism, small-artery occlusion and other causes (1). Among which, intracranial atherosclerosis (ICAS) had been major cause of acute ischemic stroke (AIS) in the Asia Pacific. It was estimated as high as 24.1% of AIS or transient ischemic attacks (TIAs) were attributed to ICAS in China (2). Management of ICAS related strokes has been challenging owing to its high rate of recurrence despite medical therapy. Recent randomized clinical trial suggested that aggressive medical therapy may result in reduction in recurrence compared with historical cohorts (3). Our group has previously observed a 2.5-fold increase in atrial fibrillation related stroke over a 15-year period (4). The inverstigator also observed a decline in ICAS related AIS as well as its recurrent stroke risk throughout the recent years. Possible mechanisms include better management of metabolic risk factors and aggressive secondary prevention. Other possible reasons are increased atrial fibrillation (AF), small vessel disease (SVD) or other stroke mechanisms. This study is aim to find the evolution of different stroke subtypes in relation to the characteristics of our stroke population over a 15-year period. This may influence territorial prevention strategy.
The investigators propose to evaluate the feasibility of Better Living After Stroke through Technology (BLAST) to help stroke survivors and family members return back to their productive and meaningful lives by proactively 1) helping them set their activity goals using ACS, 2) assessing their behavioral/functional capabilities using FBP, 3) recognizing symptoms indicative potential secondary stroke risks, 4) engaging support from online/community resources, and 5) offering tailored self-management recommendations using evidence-based strategies on how to achieve their activity goals and avoid secondary stroke based on their capabilities, stroke-related symptoms and available social resources.
The investigators will investigate the efficacy of a newly developed functional exercise device (FitMi Plus) for people in the chronic stage after a stroke compared to the FitMi Basic (i.e. without functional exercises). FitMi Plus combines objects commonly used during activities of daily living with sensors that can track and record the patient's direction and degree of movement as they perform specific functional tasks described on a computer.
Patients with stroke in the brain, due to central nervous system damage, lack of correct action patterns, limited joint movement of upper limbs, affecting the patient's performance. The Kinesio taping effect is to facilitate the muscle activity of upper limb. This program is intended to provide a treatment for patients with chronic stroke, and to observe their upper limb movements before and after using the Kinesio taping.
