Filter by:The goal of this clinical randomized control trial is to test the effect of home-based motor rehabilitation training participated by caregivers on physical function in patients with ischemic stroke ]. The main question[s] it aims to answer are: - Dose this kind of intervention method can improve the function of ischemic cerebral apoplexy patients is physical activity? - Does this intervention reduce the caregiver-related burden of patients with ischemic stroke? Participants will be randomly assigned to: (1) home-based motor rehabilitation training participated by caregivers (intervention group or (2) routine self-care group (control group). Both groups will receive assessment and health guidance on the day of discharge, with the intervention group receiving an additional home-based training program and supervision. The two groups will be followed up every week after discharge. Researchers will compare two groups to see if has great effects on physical function.
Ischemia is a severe medical condition that occurs when the blood and oxygen supply to a specific part of the body is significantly reduced or completely absent, it can affect any body part, often the legs. It is typically caused by the narrowing or blockage of an artery and can result in severe pain, tissue gangrene, and the potential loss of a limb (Amputation). This condition requires medical intervention and will not improve on its own. To diagnose leg ischemia, the doctor will conduct a thorough vascular clinical examination. Depending on the findings, further imaging tests such as duplex ultrasound, magnetic resonance arteriography (MRA), or computed tomography (CT) may be conducted. In some cases, an arteriogram may be necessary which is an x-ray of the arteries while the dye is injected into the blood vessels. Following the diagnosis, the best management course is recommended by a multidisciplinary team (MDT), considering each patient's disease pattern and overall health. Treatment options include performing a key-hole procedure, called an endovascular procedure (EVT) within the artery, where the vascular surgeon will be using a balloon to widen the artery, and/or a wire-reinforced stent which remains inside the artery serving as a scaffolding to keep it open. The primary aim of the PROMOTE GLASS study is to investigate if the Global Anatomical Staging System (GLASS) score, which is a summation of points given according to the disease pattern as seen on assessment images (Duplex Ultrasound, MRA, and CT scans) can accurately tell if the treatment using catheters and stents inside blood vessels will work well for people with ischemia in their legs. The researchers also want to see if the GLASS score can predict how well patients with ischemia will heal and if they will need further treatments in the long term after having treatment with catheters and stents inside their blood vessels. A prospective, observational study will be delivered by Cardiff and Vale University Health Board (CAVUHB). The vascular team will prospectively collect data over a 12-month period. This will be in patients undergoing elective and/or emergency primary EVT procedure, with follow-up 4-6 weeks after the procedure and at 12 months.
Peripheral arterial disease (PAD) is a disabling condition, with symptoms of muscle cramping or pain on exertion, which can substantially reduce quality of life. This study aims to see if AirGlove device improves participants circulation. This is phase 1 study and will be taken in 3 parts: Phase 1a will be undertaken in 10 healthy volunteers to assess the effects of the AirGlove device on lower limb arterial flow, tissue perfusion, quality of life and product usability following a single session. Phase 1b will be undertaken in 20 participants with intermittent claudication to assess the effects of the AirGlove device on lower limb arterial flow, tissue perfusion, quality of life and product usability both in a single session and following a 12-week trial of heat therapy. Phase 1c will be undertaken in 10 participants with critical limb ischaemia Rutherford stage 4 (rest pain). Lower limb arterial flow, tissue perfusion, pain scores, quality of life, and product usability will be assessed both in a single session and following a 2-12 week trial of heat therapy.
The aim of this study is to evaluate the safety and efficacy of remote ischemic conditioning ( RIC ) in the protection of cerebral ischemia in patients with Takayasu arteritis ( TAK ). The study was designed as a prospective, double-blind, exploratory randomized controlled study. The entire study included a screening period and a treatment observation period ( a total of 24 weeks ). All patients with cerebral ischemia of TAK will be randomly divided into RIC group and sham RIC group at 1:1 ratio. On the basis of receiving the conventional drug therapy, the patients will be treated with RIC or sham RIC treatment twice daily for six month. The clinical data of patients at baseline and each follow-up will be collected, including basic information, disease activity assessment, laboratory indicators, imaging indicators, treatment data, adverse events, etc.The Primary outcome is the mean cerebral blood flow improvement rate ( mCBF-IR ) of TAK patients after 24 weeks-treatment. Secondary endpoints include the incidence of major adverse cerebrovascular events ( MACE ) , the change value of arterial transit time ( ATT ) in pCASL hypoperfusion area compared with baseline, occurrence of RIC-related adverse reactions, the changes of hematological indexes and disease activity score, etc. This study will provide insights into the preliminary proof of principle, safety, and efficacy of RIC in cerebral ischemia in patients with Takayasu arteritis ( TAK ), and this data will provide parameters for future larger scale clinical trials if efficacious.
Mortality rates after acute ischemic stroke remain high despite continuously improving treatment. In this context, it is important to note that a relevant portion of acute ischemic stroke patients die from adverse cardiovascular events, such as myocardial infarction, rather than from complications associated with the stroke itself. A possible reason might be that this patient group often suffers from at least moderate asymptomatic coronary artery disease. This study seeks to integrate cardiac computed tomography angiography into the standard-of-care diagnostic protocol of acute ischemic stroke. The aim of this prospective mono-centric trial is to enable accurate diagnosis of therapy-relevant coronary artery disease, other concomitant cardiac findings and cardiac causes of acute ischemic stroke, without delaying stroke therapy. In the long-run, the goal is to investigate whether cardiac computed tomography angiography and the resulting therapeutic measures (interventions or medications added) can improve functional outcome and rate of adverse cardiac complications in patients with acute ischemic stroke compared to a retrospective matched-cohort of patients without cardiac CT imaging.
The goal of this clinical trial is to explore the influence of chronic RIC on collateral status evaluated by DSA in ischemic stroke patients with LAA etiology.
CALCIO is a multicentre, prospective, observational cohort study that will collect real world data on the use of intravascular Lithotripsy (IVL) with the Shockwave IVL system to disrupt calcified femoropopliteal and crural lesions in patients with chronic limb-threatening ischemia (CLTI). The primary objective of CALCIO is to understand the effectiveness of IVL in promoting wound healing and preventing amputation. The secondary objectives of CALCIO are to evaluate the immediate effectiveness of the treatment in restoring vessel patency as well as its safety and impact on patients' quality of life.
To compare between Transcranial Ultrasound , MRI and CT in patients with Hypoxic Ischemic Encephalopathyas regards diagnostic accuracy and prognostic value .
This IMPROVE trial plans to enroll 648 patients who are diagnosed with coronary artery disease and are going to take off-pump CABG in five centers in China, to access whether RIC can and improve short-term prognosis.
The purpose of this study is to determine the effect of ginkgo biloba extract on cognitive function in acute ischemic stroke.
