Filter by:PROMISE aims at identifying novel diagnostic and prognostic circulating biomarkers for patients with acute stroke and at informing on crucial yet undetected pathophysiological mechanisms driving outcome after stroke by enriching all phenotypic information available from clinical routine with in-depth quantification of the circulating proteome and metabolome as well as other entities.
To explore the pathogenesis of cardiovascular and cerebrovascular diseases through study on cardio-cerebral integration based on multimodal imaging technology, and clinical evaluation of its secondary diseases and intervention treatment. Cardiovascular and cerebrovascular diseases are leading causes of death and disability worldwide. Atherosclerosis of the large arteries of the brain and the heart has received extensive attention and in-depth research. By contrast, the epidemiology of small-vessel disease (SVD) of the brain and heart is less well established. The vascular anatomy of the heart and brain is similar in that conduit arteries are distributed on the surface of these organs with tissue perfusion achieved through deep penetrating arteries. In the heart, SVD involves the deep penetrating coronary arterioles and the subendocardial plexus of microvessels. The clinical sequelae of SVD in the heart include stable and acute coronary syndromes and heart failure in the longer term. SVD in the brain mainly involves small subcortical arterioles. If a vascular occlusion occurs, small lacunar lesions can occur, while long-term chronic ischemia caused by SVD may manifest as vascular cognitive impairment. There is a close relationship between cardiovascular and cerebrovascular diseases, and cardiovascular risk factors are related to the etiology of cerebral SVD. However, whether this relationship has a causal remains unclear. Thus, the study of cardiovascular and cerebrovascular integration based on multimodal imaging technology has important value for the diagnosis, efficacy evaluation, and prognosis judgment of cardiovascular and cerebrovascular diseases.
This study aims to investigate whether a live stream video between the on-call neurologist and the emergency medical services is feasible.
Prognosis of small vessel disease (SVD) depends on the underlying type of SVD and index manifestation. The aim of this prospective, observational cohort study is to determine the risk of different outcome events among patients with SVD according to the type of index presentation.
This is a forward-looking, open, one-arm, and real clinical trial world. The researchers plan to recruit at least 50 qualified patients. The main purpose of this study is to establish a population pharmacokinetic model of ticagrelor , explore the correlation between its blood concentration and the events of ischemia and the adverse effects of hemorrhage, and evaluate the effectiveness and safety of ticagrelor in the treatment of ischemic cerebrovascular disease.
This study aims to evaluate the incidence, clinical characteristics, and short-term prognosis of acute cerebrovascular events occurring in-hospital in patients with arrhythmias following catheter ablation. The goal is to provide evidence supporting the improvement of patient quality of life and reduction of in-hospital acute cerebrovascular complications in patients with post-ablation arrhythmias. This will also contribute to the evidence-based clinical management of such patients.
Objectives: Cerebral small vessel disease (SVD) is a common disease in patients with ischemic stroke and the most common cause of vascular dementia. Blood pressure (BP)-lowering is generally considered neuroprotective. Nevertheless, in patients with severe SVD burden, the optimal BP target is uncertain. Hypothesis: BP-lowering to a systolic BP of 120-129mmHg in ischemic stroke patients with severe SVD is not associated with impaired cerebral perfusion, nor does it associate with worsening of structural connectivity and cognitive function. Design and subjects: One-year trial where patients aged ≥50 with a history of ischaemic stroke and severe cerebral SVD will be randomised (1:1) to a systolic BP target of 120-129mmHg versus 130-140mmHg. Study instruments: At baseline and one-year, all subjects will receive a brain magnetic resonance imaging (MRI) to evaluate their cerebral blood flow (CBF) and white matter integrity. They will also receive neuropsychological batteries to evaluate cognitive functioning. In addition, subjects will receive home BP monitoring with periodic medication changes prescribed by medical doctor to ensure the target BP is achieved. Main outcome measures: Primary end-point is the change in CBF. Secondary end-points include changes in structural connectivity and cognitive performance.
The purpose of this study is to understand more about why young people who were born to a hypertensive pregnancy may have increased risk of high blood pressure and are often at increased risk of heart and blood vessel disease later in life.
This study is aimed at evaluating the potential of transcranial magnetic stimulation in patients with acute severe ischemic stroke with DoC while assessing patients with a hybrid neural network evaluation model. This model may be the basis for initiating individualized closed-loop neuromodulation treatment in patients with DoC.
This clinical trial aims to learn whether blood pressure (BP) guided by individualized cerebral autoregulation (CA) is safe and provides a better prognosis than a fixed target in patients with ischemic stroke after endovascular therapy. The BP of participants will be managed at least 48 hours after revascularization. Researchers will compare the CA-guided BP group with the fixed target BP group to mainly see if individualized BP could help more patients to have their neurological function improved at seven days.
