Filter by:Cardiogenic shock is a serious medical condition with high mortality and morbidity. This trial assesses safety, tolerability and efficacy of Adrecizumab on top of standard of care in patients with cardiogenic shock.
Chronic kidney disease (CKD) affects 8-16% of the world's population, and is independently associated with cardiovascular disease (CVD). As renal function declines, rates of major adverse cardiovascular events, cardiovascular and all-cause mortality increase. In addition to hypertension, increased arterial stiffness is characteristic of CKD, a marker of CVD risk, and an independent predictor of mortality in CKD patients. The endothelium is an important regulator of arterial stiffness, and endothelial dysfunction is a feature of CKD and a predictor of CVD. Current treatment of CKD is limited and aims to reduce blood pressure and proteinuria through the use of angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB). However, many patients still progress to end-stage renal failure and often these patients die as a result of CVD. A novel peptide, apelin, is proposed to be a potential treatment for CKD, with additional cardiovascular benefits. The AlPaCKa study investigators will carry out forearm blood flow and renal clearance studies in 25 patients with CKD and 25 matched healthy volunteers to determine the effects of apelin on cardiovascular and renal parameters. It is hoped apelin will be confirmed as a potential future treatment for CKD.
The present study will investigate the effect of prior walking on postprandial metabolism and endothelial function in centrally obese South Asian and White European men. Participants will complete two, 2-day trials in a random, crossover design separated by at least a week. On day 1, participants will either rest or complete a 60 minute walk at 60% maximal oxygen uptake. On day 2, participants will arrive at 08:00 having fasted overnight and a baseline venous blood sample and endothelial function measurement will be taken. Participants will consume a high-fat breakfast and lunch and 12 subsequent venous blood samples will be taken throughout the day at standardised intervals to measure a variety of coronary heart disease risk markers. A second endothelial function measurement will be completed 2 hours after the breakfast. Blood pressure will be measured every hour. It is expected that the South Asian participants will have impaired metabolism and endothelial function compared to their European counterparts but the bout of exercise performed on day 1 will mitigate these responses.
The investigators aim to determine the association of dietary intake on cardiovascular disease risk factors among children with overweight and obesity who are being evaluated for elevated blood pressure. The investigators will also investigate for predictors of vascular function and determine if predictors vary by level of sodium intake.
The purpose of this research study is to see the effect of taking Aged Garlic Extract (AGE) on the progression of coronary plaque, a condition called atherosclerosis, in people diagnosed with Diabetes.
The primary purpose of this project is to assess the efficacy (effectiveness) of plant-based nitrate tablets to elevate nitric oxide in your system as measured by saliva and effect on lowering blood pressure (BP), supporting blood vessel function in men and women with hypertension.
The purpose of the study is to look at the effect a dietary supplement called CEAG [Curcuminoids, EPA (Omega-3), Astaxanthin and Gamma Linolenic Acid (GLA)] has on inflammation and endothelial (inner layer of the blood vessels) function and whether it causes a lowering of blood pressure.The endothelium plays in an important role in blood pressure.
This study seeks to confirm and extend previous finding that four weeks of daily intake of 40 g of walnuts improve microvascular function, increasing the reactive hyperemia index (RHI), effects which were greatest in individuals with the worst initial RHI and correlating to circulating levels of vasoactive plasma epoxides. The current trial will enroll postmenopausal women who are at risk for cardiovascular disease due to their menopausal status and increased central adiposity. The initial trial focused on non-esterified (i.e. plasma) derived oxylipins, but substantial and unique changes were also observed in the esterified lipoprotein pool. The current study will add the esterified lipoprotein pool, important, as the mechanisms by which walnut intake influences endothelial function are currently undefined, but may include lipoprotein induced modulation of vascular hemostasis. As a secondary objective, primary metabolism and urolithin metabotype will be analyzed as a way to capture the influence of potential differences in habitual diet and metabolism on physiologic response. Therefore, this study will combine measures of cardiovascular physiology, metabolomics, and walnut-derived metabolite analyses to assess the 12 week influence of 40 g of daily walnut intake on the health of overweight and obese postmenopausal women.
Interventional study comparing effect of two regimes of fluid challenge in patients with sepsis and in patients undergoing elective major surgery on glycocalyx by using perfused Boundary Region in sublingual microcirculation.
The aim of the study is to assess if abnormal lipid levels in childhood could cause early damage of the inner layer of the vessels, the endothelium. Dysfunction of the endothelium is the first event in the development of atherosclerosis, is present at all stages of atherosclerosis and is potentially reversible in childhood. It has been suggested that dyslipidemia, via its detrimental effects on endothelium, could impair renal function. This study will assess the dysfunction of the kidneys in children with dyslipidemia.
