Filter by:The purpose of this study is to investigate the change of cholesterol efflux capacity in patients with coronary artery disease treated with secondary prevention drugs, and the correlation with the prognosis.
The study procedure of simultaneous VFSS and DDS measurement will be completed in one day and the subject will be followed within 2 business days after the study procedure to monitor for adverse events.
Personalized therapy as prophylaxis in ischemic stroke patients is not yet an option. From patients with ischemic heart disease, we know that patients with in vitro high on treatment platelet reactivity (HTPR) have an increased risk of stent thrombosis following per-cutaneous coronary intervention. Other studies have shown association of CYP2C19 genotypes with different responses to the anti platelet drug Clopidogrel. We measure HTPR in ischemic stroke patients on increasing doses of clopidogrel and investigate the CYP2C19 genotype for each patient.
Stroke is the first most common cause of death in China and one of the major causes of functional disability in the adult population.The burden of stoke is significantly increased in China in recent years. In order to investigate the prognosis of stroke, with diagnostic and treatment information of traditional Chinese medicine (TCM), and assess the effectiveness and safety of TCM for stroke in southern China, the investigators will conduct this multicenter prospective registry study in southern China. This study will recruit 10,000 consecutive eligible patients with acute stroke from more than 50 hospitals. 24 months follow-up will be carried out on-site in hospitals and by telephone to track endpoint (including all-cause mortality, composite cerebrovascular and cardiovascular events at one and two year follow up, and neurological and functional assessments).
Incidence of strokes has increased these last 20 years in young population. This rise could be linked to alcohol, tobacco or drug use like cannabis. Cannabis has previously been descripted as a potential factor of reversible vasoconstriction. The main objective is to show that an exhaustive assessment of a stroke facing a young person frequently lead to a diagnostic of reversible vasoconstriction due to cannabis use. Evaluation will focus on prevalence of strokes secondary to a reversible vasoconstriction attributable to cannabis in young subjects. There's a real public healthcare interest in terms of primary and secondary prevention to evaluate the role of cannabis as a risk factor of stroke in young population.
Stroke patients with severe upper limb movement deficits have limited treatment options and often remain severely handicapped at the chronic stage. Recent findings have suggested that poor motor recovery can be due to severe damage of the cortico-spinal tract (CST), the neural fibres connecting the movement regions of the brain to the spinal cord. Hence, to improve recovery of upper limb movements it will be crucial to re-establish and strengthen CST projections. Recent studies provided evidence that closed-loop brain computer interface-driven electrical stimulation of the paretic muscles can induce clinically important and lasting recovery of upper limb function, even in patients with chronic, severe motor affection. In this treatment approach, movement intentions of the patients are detected with electroencephalography and real-time analyses. This triggers an electrical stimulation of affected upper limb muscles. In this study, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to voluntary activation of primary motor cortex, as detected by a brain-computer interface (BCI), can help restore CST projections. This might improve recovery of patients with severe upper limb movement deficits. Treatment will be started within the first 8 weeks after stroke onset.
A stroke is the second cause of deaths after heart attack, one of the most important causes of malfunction as far as adults are concerned and the second as for the frequency cause of dementia. In spite of a possibility of the therapy of stroke ( tissue plasminogen activator) and recognized most of risk factors there is expected that incidence rate on stroke connected with ageing of the society will be growing. It will cause medical and social consequences. There are many of potential causes of cardiac strokes, which are not entirely examined. More over many cryptogenic strokes are presumed to have an embolic etiology, and the frequent cause of these kind of strokes at young age is probably the mechanism of paradoxical embolism through patent foramen ovale. As far as the investigators are concerned, at present there is lack of any recommendations for these scientific hypothesis.
Sickle Cell Disease (SCD) is a rare disease occurring in an estimated 100,000 individuals, often poor and underserved, in the US. Silent and overt strokes contribute significantly to morbidity in adults with SCD, resulting in functional impairment, challenges with school and job performance, and premature death. Five NIH-funded randomized controlled trials have identified therapies to prevent silent and overt strokes in children with SCD, including monthly blood transfusion therapy (for preventing initial and recurrent strokes) and hydroxyurea (for preventing initial strokes). Despite the observation that at least 99% of children with SCD in high-income countries reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with silent strokes and ~10% with overt strokes), no stroke trials have established therapeutic approaches for adults with SCD. For adults with SCD, inadequate evidence-based guidelines exist for secondary stroke prevention strategies. Applying stroke prevention strategies in children may not be effective for stroke prevention in adults with SCD, particularly given the high rate of co-morbidities. Identifying subgroups of adults with SCD and higher incidence coupled with the contribution of established stroke risk factors in the general population (smoking, diabetes, obesity, renal disease) will provide the requisite data required for the first-ever phase III clinical trials focused on secondary stroke prevention in adults.
Stroke is one of the leading causes of death worldwide and the main cause of incapacity. Currently, the only therapies for acute ischemic stroke (AIS) patients are the administration of recombinant tissue plasminogen activator (rt-PA) and/or endovascular treatment. Unfortunately, many patients cannot benefit from these therapies due to contraindications or evolution time. Neuroprotective therapies could not only increase the benefits of available reperfusion therapies but also provide an option for patients who are not candidates for these treatments. Remote ischemic conditioning, consisting on brief episodes of transient limb ischemia, represents a new paradigm in neuroprotection. It can be categorized in pre-, per- or postconditioning, depending on the moment of application. According to studies in coronary ischemia, remote ischemic perconditioning (RIPerC) during the ischemic event is safe, cost-effective, feasible and associated with a reduction in myocardial injury. The investigators aim to conduct a multicentre study (5 university hospitals) of pre-hospital RIPerC in AIS patients (within 8 hours of stroke onset), which would include 572 stroke code activated patients (286 would undergo RIPerC and 286 would be sham). Our hypothesis is that RIPerC would be safe and would induce endogenous neuroprotective phenomena associated with good outcomes in AIS patients whether treated with revascularization therapies or not. Moreover, the development of systemic ischemic tolerance should provide metabolomic and lipidomic signatures that would present an opportunity to find specific molecular markers (biomarkers). The main objectives will be to assess: 1) RIPerC clinical benefits in AIS, 2) whether RIPerC is safe not only in AIS but also in all cases of stroke code activation, 3) whether RIPerC is associated with a reduction in cerebral infarct size and 4) metabolomic and lipidomic signatures of the RIPerC effect.
