The purpose of this clinical study is to determine whether the addition of an oral Factor XIa Inhibitor to Aspirin and Clopidogrel is more effective than standard therapy in secondary stroke prevention. The safety of this treatment will also be studied.
Recent prospective observational data has established that distal blood flow compromise measured using noninvasive quantitative magnetic resonance angiography (QMRA) identifies a high risk subgroup of patients with symptomatic atherosclerotic vertebrobasilar (VB) steno-occlusive disease, serving as an imaging biomarker for future stroke risk. The currently proposed study aims to determine if an endovascular intervention, submaximal balloon angioplasty, can be performed with adequate safety in this high risk subgroup of flow-compromised patients with VB stenosis. The study will also examine as secondary aims, the effect of the intervention on distal flow augmentation and on subsequent posterior circulation ischemic events.
TELECAST-TIA is a prospective single-center study evaluating guideline-based transient ischemic attack (TIA) treatment at an Acute Stroke Ready Hospital (ASRH) pre- and post-initiation of a specialist telestroke inpatient rounding service. TELECAST-TIA will study the following clinical endpoints: diagnostic stroke evaluation, secondary stroke prevention, health screening and evaluation, stroke education, inpatient complications, and stroke recurrence rates. Additional relevant non-clinical data will include patient and provider satisfaction scores, transfer patterns, and a cost analysis.
Stroke is a significant medical problem with 150,000 events occurring per year in the UK and incurring healthcare costs of £4 billion per year. Fifty percent of strokes will leave a lasting disability on first manifestation and 10-15% (roughly 16,500 per year) are unheralded ischaemic events in previously asymptomatic Carotid artery disease. Carotid Artery Disease is caused by the formation of an atherosclerotic plaque in the vessel. Stroke or TIA occurs when plaque or adherent thrombus breaks off and embolises to the brain, blocking off its blood supply. Hence, a carotid plaque is said to be symptomatic if it has caused a Stroke or TIA in the territory of the brain supplied by that vessel in the previous six months. Currently, the degree of stenosis (narrowing) of the artery by doppler ultrasound is the main assessment performed. Doppler ultrasound measures stenosis and elevation of blood flow velocity in the artery prior to surgical intervention. However, it has been shown that the degree of stenosis is a poor predictor of stroke as many asymptomatic patients have severe stenosis and many symptomatic patients have moderate stenosis. Stenosis is a two dimensional assessment of a 3-D structure. Other features of the plaque should be considered including the volume of the carotid plaque and its constituents. Carotid Plaque Volume has been measured in 339 individuals, with plaque volume being higher in symptomatic than asymptomatic individuals. In this study, plaque volume did not correlate with stenosis degree. No studies have been conducted measuring the change in carotid plaque volume and morphology following a stroke. This pilot study will perform serial duplex scans on recently symptomatic individuals over a 12 week period and observe the changes in Plaque Volume and morphology. This will attempt to prove that carotid plaque volume is a better predictor of stroke than stenosis. The investigators will also aim to identify other plaque features that may have an important role in predicting stroke risk. Documenting the timescale of change in plaque volume will aid us in defining appropriate timescales for treating the symptomatic population and when those having medical management's risk has returned to baseline. Observing the change in plaque immediately after stroke will improve our knowledge of the changes in plaques that lead to symptoms and may in the future help us predict which patients with asymptomatic carotid stenosis need operation.
This study will test the feasibility of a home blood pressure telemonitoring (HBPTM) system in patients with minor stroke or TIA in the past year. The telemonitoring system will consist of a blood pressure machine and an online survey to submit blood pressure measurements. The investigators want to test whether patients can persistently use the telemonitoring system with ease and whether telephone instructions for blood pressure medications from the research nurse can be correctly understood. A secondary purpose of this study is to look at the effects of telemonitoring in blood pressure and stroke recurrence.
The CARDIOSTROKE is a randomized trial comparing mobile-device assisted control of hypertension together with screening of occult atrial fibrillation to standard care in patients with recent ischemic stroke or transient ischemic attack.
Study design is a perspective, multi-center, historial control study of acute ischemic stroke patients. For achieving the target of diagnosis and treatment KPI (Key performance indicator) of AIS patients and improving the defects of the traditional working mode, our center developed the medical records data acquisition and KPI statistics system based on computer scan. This method guarantee the authenticity of the data, It computes the KPI of the corresponding medical institutions in the corresponding period and gives feedback on a regular basis. This study aims to explore whether this new working mode can continuously improve the overall KPI of all hospitals in Zhejiang province, and thus reflect the improvement of quality and standardization of medical service in AIS patients.
Ischemic stroke occurs when an artery to the brain is blocked. If the artery remains blocked for more than a few minutes, the brain cells may die. This is why immediate medical treatment is critical. Luotai® is the brand name of Panax notoginseng finished product. 2 kinds of formulation are available, the lyophilized powder for Injection and gelatin based soft capsule. They are being used for decreasing incidence of cerebral infarction or ischemic stroke. This study will be conducted as an observational study, regarding the safety, effectiveness of Luotai treatment in acute ischemic stroke patients. This study will be carried out in approximately 360 patients with acute stroke in 6 hospitals in Vietnam - Bạch Mai Hospital, 108 Military Hospital, 103 Military Hospital, Trung Vuong Hospital, Phu Tho General Hospital, 115 Hospital. STUDY PROCEDURES: Participants will be enrolled in an unbiased manner (by consecutive sampling) and consecutive sampling method. The investigators will record participants' information required by the Case Report Form. The study which last for about 3 months, and in each of the visit, the information will be collected includes informed consent, demographic data, ischemic stroke assessment, concomitant medication, adverse reactions. A travel transportation allowance of VND 300,000 will be given for each visit. Participants will receive Luotai and other medications according to the local hospital practice in accordance with the terms of the local marketing authorization in Vietnam. The recommended dosage of Luotai is: Luotai™ injectable lyophilized powder for consecutive 14 days, Luotai soft capsules for 65 days. The participation of the study is fully voluntarily. Patients decide not to participate in the study will not be disadvantaged in any way. All collected information from participants is protected as confidential. The results of the study may be published in medical literature, but participants will not be identified. This study does not include any procedure/test that there were not indicated according to local clinical practice. There is no specific associated risks or discomforts in this study related to the participation. The results of this research may guide in further understanding the Ischemic Stroke.
Interventions to improve health behaviour in patients with resent acute stroke are not well established. This study will evaluate the feasibility and effect of an early initiated counselling intervention targeting smoking, physical activity, and adherence to preventive medication, with regular follow-up sessions, in patients with acute minor stroke or transient ischemic attack who are discharged home.
Large-artery stenosis plays an important role in the occurrence of ischemic stroke. The primary purpose of this study is to evaluate the efficacy and safety of intensive antiplatelet therapy versus standard antiplatelet therapy and early intensive statin therapy (80mg atorvastatin) versus delayed intensive statin therapy (40mg atorvastatin) and intensive antiplatelet combined with early intensive statin therapy (80mg atorvastatin) versus standard antiplatelet combined with delayed intensive statin therapy (40mg atorvastatin) in reducing the risk of stroke at 90 days in patients with acute and high-risk symptomatic extracranial or intracranial arterial stenosis.
