Filter by:The CSSPT study is a multi-center, randomized, double blinded, placebo-controlled secondary stroke prevention trial in China to determine whether the addition of folic acid and vitamin supplements will reduce recurrent stroke events and other combined incidence of recurrent vascular events and vascular death.
The purpose of this study is to determine the frequency, characteristics, and consequences of vulnerable carotid artery plaques ipsilateral to an acute ischemic stroke or TIA in the territory of the internal carotid artery.
The carotid arteries are blood vessels in the neck that supply blood to the brain. Carotid stenosis disease is defined as a narrowing of these arteries due to the build up of plaque. The plaque material can also break off and move into the brain. The resulting blockage of blood supply to a portion of the brain is what causes 80% of all strokes. One treatment option is to have surgery on the carotid artery and remove the plaque. This procedure is called a carotid endarterectomy (CEA). There is evidence that proves CEA reduces the risk of stroke. The objective of this research project is to determine who is most likely to benefit from CEA surgery.
The aim of this study is the evaluation of two usual care strategies after stroke or TIA : achieved target LDL-C of 100 mg/dL (+/-10 mg/dL) or less than 70 mg/dL. Investigators will use the statin and titrate the dosage to achieve the target assigned by randomization in monotherapy or in combination with ezetimibe or other drugs. The primary end-point is the occurrence of recurrent non fatal stroke, non fatal MI, and vascular death in each group. 3760 patients will be recruited and followed for eight and a half years maximum.
The objectives of the trial of a medication-coach program for patients with stroke or transient ischemic attack are to pilot test the study design, the intervention components and the data collection forms and refine them for a larger trial whose goal will be to improve long-term adherence to stroke prevention medications.
Does tomato extract improve blood vessel function in healthy people and people with cardiovascular disease? Atherosclerosis ('furring' of the arteries) affects the functioning of blood vessels, narrowing and eventually blocking them, causing conditions like heart attack and stroke. The Mediterranean diet, which is rich in tomatoes and tomato-based products, has been shown to be associated with a reduced risk of blood vessel damage. In this double blind, placebo-controlled randomised study, the investigators will investigate whether a food supplement containing a standardised extract of tomato improves blood vessel function in both healthy people (aged 40-80), and people with a history of cardiovascular disease. The food supplement is on sale to the public, and the investigators are testing the standard dose. Approximately 72 people will take part at the Clinical Pharmacology Unit at the ACCI Building, Cambridge University Hospitals NHS Trust. After they have passed screening tests, participants will be allocated by chance to receive either the tomato extract product (Ateronon), or a matching placebo (a dummy capsule with no active ingredients), which they will take once a day for 8 weeks. At the beginning and end of the treatment period, the investigators will test blood vessel stiffness using an ECG machine and external probe. The investigators will also measure forearm blood flow, which involves infusing 3 separate agents that affect how the lining of the blood vessel wall works, and helps to assess whether this is affected by the study treatment. Blood tests will also be used to look at how the food supplement is working and its effects on cholesterol and markers of inflammation. Including the screening period, and a follow-up telephone call two weeks after the end of treatment, participants will be in the study for 14 weeks.
The study aims to observe the short term effect (3-month) of sleep disordered breathing (SDB) on cardiovascular parameters, heart rate variability, endothelial function and surrogate markers of atherosclerosis after acute cerebrovascular events (ACE). The long-term effect (6-24-month) of Continuous Positive Airway Pressure (CPAP) on clinical vascular outcome, cardiovascular parameters, evolution of surrogate of atherosclerosis heart rate variability and endothelial function after ACE is observed over 24 months. A preventive effect of CPAP therapy on cerebro-vascular events in patients with moderate-severe obstructive SDB without sleepiness after ictus or transient ischaemic attack will be evaluated.
The purpose of this study is to determine whether an outpatient program can reduce the risk of recurrent stroke.
The purpose of this study is to determine the effectiveness of interventions to improve adherence to medication and healthier lifestyle choices on blood pressure over a 6 month period in a group of people at high risk for recurrent stroke events. The participants have already had a stroke or TIA, and have uncontrolled blood pressure, as well as problems with memory and problem-solving, or miss taking medications, or who do not believe in the effectiveness of their medications. Interventions focus on motivational interviewing, adherence counseling with memory cuing, and self-monitoring of blood pressure.
The purpose of this study is to evaluate if a peer-led stroke recurrence prevention intervention, versus usual care, will help reduce risk factors for recurrent strokes among adults in Harlem.
