Filter by:This is a randomized controlled trial designed to evaluate the role of screening for and intervening on patients with high on treatment platelet reactivity undergoing lower extremity arterial endovascular interventions.
The purpose of this study is to test whether sodium nitrite affects the expression of cellular proteins important for metabolic and vascular function in vascular offcuts and cardiac biopsies taken from patients undergoing coronary artery bypass grafting (CABG) surgery.
This study attempts to reduce social inequality in cardiovascular health by performing an interventional screening trial on how best to decrease cardiovascular disease (CVD) among people with low social status.
The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.
To determine long-term outcomes, recurrence rates, and treatment needs in Polypoidal Choroidal Vasculopathy (PCV). Specifically, to describe the long-term outcomes, recurrence rates and treatment patterns PCV patients 5 years after first presentation. This study will also evaluate whether polyp closure within the first 12 months of therapy is associated with better long-term visual outcome and will also determine the risk of disease development in the fellow eye
Several Drugs used in routine care in oncology induce rare but often severe or fatal cardiovascular or metabolic side effects. This study will investigate, evaluate, report and treat the cardiovascular side effects of anticancer drugs, through a specific cardiovascular routine checkup and follow-up taking place in several Cardio-oncology programs throughout France. The different including centers will be: Assistance Publique - Hôpitaux de Paris (APHP.6: Pitié-Salpétrière, Saint Antoine and Tenon's hospitals, Paris, France).
The investigators hypothesise that a home-based standardised exercise intervention with 2g of carnosine daily for 6 months will improve walking endurance in 104 patients with PVD aged 40-80 years compared to placebo and exercise through stabilisation of HIF1-α in the ischaemic leg. Aims Aim 1: Determine whether in patients with PVD, carnosine in addition to exercise improves: 1. walking endurance (6-min walk test; primary outcome); 2. initial claudication distance (ICD), and absolute claudication distance (ACD; treadmill), cadence, resting and exercise ABI; and 3. central blood pressure, endothelial function, arterial (aortic) stiffness, lipid profile; and 4. quality of life as determined by EuroQol-5D (all secondary outcomes). 5. Improve cognitive function (global cognitive score formed by a composite of 7 cognitive tests) Aim 2: Delineate the mechanisms by which carnosine improves walking endurance: 1. protein expression of pro-angiogenic and carnosine related genes, including carnosine transporters in the skeletal muscle biopsies, EPCs in peripheral blood and quantitative proteomic studies. 2. other mechanisms demonstrated in animal studies including plasma inflammatory markers, serum and urinary advanced glycation (AGE) and lipoxidation (ALE) end-products (tertiary outcomes). This trial will provide evidence for use of carnosine as a therapeutic intervention for PVD patients and, if positive, will have immediate clinical application.
This study will investigate the prevalence of allograft vasculopathy and unexplained graft dysfunction during long-term follow-up after heart transplantation. Risk factors as well diagnostic approaches will be investigated.
The investigators will collect omental tissue (research surgical excision) and placental tissue (standard of care clinical delivery) from both preeclamptic and non-preeclamptic women during their c-section and use these samples to study the blood vessels, specifically the expression/activation of the AT2R.
Increasing evidence suggests that systemic low-grade inflammation may be a driving force of cardiometabolic complications, such as vascular dysfunction, atherosclerosis and ischemic heart disease. Thus, we will investigate the role of inflammation in cardiovascular disease.
