Filter by:Stroke remains the most dangerous and frightening complication of atrial fibrillation (AF). Numerous factors predisposing to peripheral embolism in patients with AF have been well defined, documented and included in the CHA2DS2VASC score. Although proper anticoagulation minimizes the risk attributable to "known" risk factors, stroke may still occur. Thus, "unknown" risk factors may play an important role in stroke risk stratification in patients with AF. The investigators assume that one of the important "unknown" risk factor is left atrial appendage (LAA) morphology. The ASSAM study is planned to include 100 patients after ischemic stroke or transient ischemic attack (TIA) and known status of anticoagulation at the time of stroke. The control group will consist of 100 patients scheduled for AF ablation without a history of stroke or TIA.
PROMISE is a prospective, nationwide, multicenter, longitudinal cohort study, focusing on hospital intravenous thrombolysis process reengineering for acute ischemic stroke (AIS). With a proposed "Reengineered Process Framework" for intravenous thrombolysis process by the PROMISE study steering committee, about 30 medical centers enters would be recruited nationwide, and each center would include consecutive AIS patients with an onset-to-door time (ODT) of less than 3.5 h. The investigators hypothesize that the proposed "Reengineered Process Framework" is suitable and feasible for hospitals in mainland of China; the rate of intravenous rt-PA thrombolysis in ischemic stroke patients with an ODT of less than 3.5 h would be more than 20% or be increased by 40% as compared with baseline; the proportion of patients with a door-to-needle (DNT) time of less than 60 min would be more than 20%, or be with an increase by ≥ 40% as compared with baseline.
Medical progress and modification of lifestyles have prolonged life expectancy, despite the development of chronic diseases. The support and care are often provided by a network of informal caregivers composed of family, friends, and neighbors. They became essential to help maintening the elderly persons to live at home. It has been demonstrated that the importance and the diversity of informal tasks may jeopardize their own physical, mental and social well-being. The aim of the Informal Carers of Elderly Cohort is to define, through a longitudinal study of their life course, the profiles of caregivers of patients with a diagnosis of one of the following diseases: cancer (breast, prostate, colon-rectum), neuro-degenerative diseases (Parkinson's disease, Alzheimer's and similar diseases), neuro-vascular diseases (Cerebrovascular Accident (CVA)), Age-related Macular Degeneration(AMD) and heart disease (heart failure), aged ≥ 60 years old and living in Burgundy or Franche-Comte. By following the different phases of the caregiving relationship from the announcement of the diagnosis, it will be possible to assess the quality of life of caregivers and evaluate the implementation of a pragmatic social action to help informal caregivers through a randomized intervention trial nested in the cohort. Thanks to an analytical and longitudinal definition of the profiles of informal caregivers, this study could gather precise information on their life courses and their health trajectory by identifying the consequences associated with the concept of their role of aid in care. In addition, the randomized intervention trial will explore the efficacy, in terms of quality of life, and efficiency of a social action to support the caregivers. These data will allow to identify strategies that could be used to improve the existing sources of aid and to propose new approaches to help caregivers. This study will provide the opportunity to identify the most relevant means of support and to give an impulse for new healthcare policies.
This study seeks to investigate the capillary index score (CIS) to further improve patient selection of endovascular treatment (EVT) in acute ischemic stroke (AIS). The hypothesis or idea being tested: Patients with favorable CIS who are successfully revascularized with EVT can have successful outcomes with an extended time window for treatment.
Medication adherence is a major factor to prevent vascular recurrence after a first ischemic stroke. Nevertheless, it is suboptimal and the implementation of specific interventions are needed to improve it. A patient - centered and pluriprofessional structured intervention, targeting the medication, introduced at hospital discharge and continued at home (by regular telephone contact) could improve medication adherence one year after stroke. This intervention would consist of semi structured interviews patient-pharmacist at different times during one year after stroke. The information about the therapeutic management of the patient will be shared between healthcare professionals : general practitioners (GP) and community pharmacists (CP), hospital clinical pharmacist (HCP) and physician (HPhys). It will allow for decrease of the recurrent stroke and others cardiovascular complications based on a better adherence to preventive medication. Furthermore the decrease of the iatrogenic events and the improvement of the quality of life of patients may be also associated.
The purpose of this study is to estimate the clinical relevance of monitoring patients with acute ischemic stroke with 48 hours' inpatient cardiac telemetry in relation to evaluate the presence of brief runs of premature atrial complexes and new diagnosed atrial fibrillation. Furthermore to evaluate the prognostic significance of brief runs of premature atrial complexes in relation to develop atrial fibrillation, recurrent stroke/transient ischemic attack and death.
Spasticity is one of the most common disorders in patients with central nervous system diseases such as stroke. Transcranial direct current stimulation stimulation (tDCS) is a noninvasive tool that can be used to modulate cortical excitability of the leg motor area, and the spinal motor circuits as well. Objective:The objectives of this study is to examine the efficacy of anodal tDCS combined with Biodex balance training on lower limbs spasticity in chronic stroke patients using laboratory and clinical assessments.
Neovascularization Induced by Mechanical Barrier disrUption and Systemic erythropoietin in patients with cerebral perfusion deficits (NIMBUS trial)
The cerebrovascular diseases can be approximately divided as two types, namely ischemic and hemorrhagic stroke. Intravenous thrombolysis within 3-4.5 hours is highly recommended for acute ischemic stroke patients. But it's difficult to diagnose the ischemic stroke with the hemorrhagic stroke from the early symptoms and signs. It's with high risk of enlarging the hematoma if the patients with hemorrhagic stroke received the thrombolytic drugs. And time cost by CT or MRI examination is likely to responsible for missing the narrow time window and poor prognosis of stroke patients. Consequently, seeking for a noninvasive, rapid, portable and inexpensive diagnosis method which can sensitively distinguish the stroke type before CT or MRI examination would be very helpful in treating the ischemic stroke patients. Because of the blockage in the cerebral supply artery, the heat from circulatory system will sharply decrease in infracted hemisphere among the ischemic stroke patients. The reduced brain temperature influenced the temperature on the ipsilateral forehead according to the data of our animal and preliminary clinical trial. In contrast, the temperature of the ipsilateral hemisphere showed a mild increase among the ischemic stroke patients in our preliminary experiment. The difference of the temperature tendency on the ipsilateral forehead has a great chance to be an early physical mark. In our study, 30 ischemic stroke patients and 30 hemorrhagic stroke patients will be recruited. In the process of recruitment, the patients with acute stroke attack in no more than 4.5 hours will be collected the temperature at the five point without head coverage, including ipsilateral tempora, ipsilateral forehead, galbella, contralateral forehead, and contralateral tempora. Then the stroke would be recruited into the ischemic and hemorrhagic group according to the later CT or MRI results in the hospital. The accuracy and sensibility of early brain temperature in distinguishing stroke type would be tested in comparison with the diagnosis of imaging examination.
The purpose of this study is to examine the role of Hyperbaric Oxygen Therapy (HBOT) in improving neurological function in patients who are 6 to 36 months post ischemic stroke.
