Active clinical trials for "Cerebrovascular Disorders"

Coronary heart disease and stroke are belong to the atherosclerotic vascular disease (ASCVD). When both occur at the same time, the mortality rate is 19%-37%. Especially when ischemic stroke occurs in patients with acute myocardial infarction, the mortality rate is as high as 36.5%. At present, there is a lack of co-management for the cardio-cerebrovascular diseases. Some studies have explored the disease management based on Internet +, but there are still challenges in personalized management and improving adherence. Based on Internet + 's "co-prevention and co-management" model of cardio-cerebrovascular diseases, this study plans to provide personalized intervention by smartphone App to improve the patients' self-management, in order to reduce the incidence and mortality of atherosclerotic cardio-cerebrovascular events in the high-risk population of cardio-cerebrovascular diseases.

The specific study aims will be: To design and develop the hardware and software of the VR+MT and MR+MT systems. To test the feasibility of the VR+MT and MR+MT systems from the patients and to collect the feedback of users with respect to their experiences. To examine the treatment effects of VR+MT and MR+MT compared to the traditional MT (i.e., control group) in patients with stroke by conducting a randomized controlled trial. To identify who will be the possible good responders to VR+MT and MR+MT based on their baseline motor functions and mental imagery abilities.

The aim of the study is to determine if 2-week repetitive transcranial magnetic stimulation at the subacute phase of stroke (between day 7 and day 14) improves significantly arm motility at 3 months with remaining effect at one year, without significant adverse effect.

Background: A stroke occurs when not enough blood reaches the brain. Sometimes stroke causes changes in certain brain matter. This is called white matter hyperintensity (WMH) and can lead to mental decline. But not all WMH is caused by stroke. Not all people with WMH experience mental decline. Researchers want to learn more about WMH. They want to see if it is related to disruptions in the blood-brain barrier. Objective: To better understand the how blood-brain barrier disruption is related to white matter hyperintensities. Eligibility: Adults at least 18 years old who have been admitted to a study site with stroke-like symptoms Design: Participants will be screened with an MRI scan and cognitive tests. Participants will have 11 visits over 6 years. Each visit will be 3-4 hours. At each visit, participants will: Update their medical history Have a thin plastic tube (catheter) inserted into an arm vein by needle Have an MRI. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will be in the scanner about 60 minutes, lying still for up to 20 minutes at a time. They will get earmuffs for loud sounds. Have a dye injected through the catheter during the MRI Have tests of movement, language, and cognition Some participants will have an extra visit for an MRI in a stronger scanner (7T MRI). Participation for some participants will be authorized by their legal representative.

Background: Alteplase is the only approved acute drug treatment in ischemic stroke and aims at dissolving arterial clots causing cerebral ischemia. The overall benefit of alteplase is substantial. However, there is considerable room for improvement as 2/3 of patients with large clots may not achieve reopening of the vessel and up to 40% of the patients remain severely disabled or die. Tenecteplase, a modified tissue plasminogen activator, has been shown to be a more efficient and safer thrombolytic drug than alteplase in pre-clinical studies. Tenecteplase has replaced alteplase as thrombolytic treatment in myocardial infarction and may also be the drug of choice in ischemic stroke. Tenecteplase and alteplase had a similar safety profile in the NOR-TEST trial and there were no differences in efficacy between the two treatment groups. However, a majority of patients had mild stroke which may be associated with a natural favorable prognosis. In spite of these neutral results, tenecteplase has the potential to replace alteplase as the drug of choice, based on a better pharmacological profile and a simpler practical administration. There is, however, need for a higher number of patients to prove the efficacy and safety of tenecteplase. Hypothesis: Tenecteplase 0.4 mg/kg is non-inferior compared with alteplase 0.9 mg/kg.

PROMISE aims at identifying novel diagnostic and prognostic circulating biomarkers for patients with acute stroke and at informing on crucial yet undetected pathophysiological mechanisms driving outcome after stroke by enriching all phenotypic information available from clinical routine with in-depth quantification of the circulating proteome and metabolome as well as other entities.

This study will assess the rate at which rosuvastatin will achieve LDL targets in African American patients with previous history of stroke or TIA.

To characterize the natural history and biologic spectrum of sleep disordered breathing (SDB) and other sleep problems and disorders, and test hypotheses regarding the causes and consequences of SDB and other sleep problems and disorders.

A computerized registry of cardiovascular disease patients in a large health maintenance organization in Israel. The registry is aimed to be used by health professionals to identify cardiovascular disease patients and to follow the courses of their illnesses and risk factors.

This is a prospective study of the environmental and genetic factors that influence the development of cardiovascular disease (CVD) in African American men and women. The cohort is a collaboration among multiple institutions (Jackson State University, Mississippi State Department of Health, Tougaloo College, and the University of Mississippi Medical Center), the National Institute on Minority Health and Health Disparities (NIMHD), and the National Heart, Lung, and Blood Institute (NHLBI).
