Filter by:Children and adolescents with chronic kidney disease (CKD) are at high risk for cardiovascular (CV) morbidity and mortality. Recent studies suggest that pediatric patients with even moderately impaired kidney function may be afflicted with significant early cardiac and vascular abnormalities. The pathogenesis and the natural course of CV comorbidity in pediatric CKD patients is still elusive. In this multicenter, prospective, observational study the prevalence, degree and progression of CV comorbidity in children will be characterized and related to CKD progression. The morphology and function of the heart and vessels will be monitored by sensitive, non-invasive methods and will be compared with aged matched healthy controls. Multiple potential clinical, anthropometric, biochemical, and pharmacological risk factors will be monitored prospectively and will be related to CV status. Genotyping might identify predisposing genetic factors for progression of CV comorbidity and underlying nephropathies.
The purpose of this study is to determine if treating periodontal infections (gum disease) will reduce markers of systemic inflammation in patients at risk of cardiovascular diseases.
Rationale: Survivors of childhood cancer are at an increased risk of developing cardiovascular risk factors as well as early cardiovascular disease, likely due to the intensive therapeutic regimen used to treat their cancer. Purple grape juice (PGJ) is a rich source of flavonoids and a powerful antioxidant. Clinical studies in both diseased and healthy adults suggest that daily consumption of PGJ contributes to increased antioxidant capacity, reduced low-density lipoprotein (LDL) oxidation, and improved vasodilation. Purpose: This randomized clinical trial is evaluating whether purple grape juice can reduce oxidative stress and improve the vascular health of survivors of childhood cancer in the early stages of cardiovascular disease.
This study is carried out to assess whether dapagliflozin improves glycemic control, decreases fasting plasma glucose levels, body weight and blood pressure when added to patient's existing medications and how it compares with their usual treatment without added dapagliflozin. Safety data will be collected and analysed to confirm that treatment with dapagliflozin is safe and well tolerated in patients who have diabetes and cardiovascular disease
The purpose of this study is to evaluate the safety of an IV infusion of GW856553 in healthy volunteers.
The overall aim of the Health2010-14 is to monitor the prevalence and trends of common chronic diseases (osteoporosis, diabetes, cardiovascular disease, asthma, allergy, and eczema) that are often un-diagnosed in the general population as well as biomarkers of micronutrient status. Specific aims include identification of novel lifestyle and genetic risk factors for the above diseases by investigating gene-lifestyle interactions.
The purpose of this study is to assess the relationships between dose and time of consumption of stearidonic acid (SDA) and eicosapentaenoic acid (EPA) on EPA enrichment of red blood cell (RBC) membranes in men and women.
Eating a diet high in fat contributes to the development of atherosclerosis (hardening of the arteries). Acute fat consumption increases levels of fat in the blood and temporarily reduces the ability of blood vessel to dilate (open up to carry additional blood). A similar response is observed during infusion of Intra-Lipid (a fat emulsion used for intravenous nutrition). The present study is designed to help us understand the effects of a fat load on blood vessel function. We will measure arterial dilation using non-invasive techniques before and at the end of a 5-hour infusion of Intra-Lipid in healthy subjects. Subjects will then take the approved drug metformin for two weeks and return for repeat studies of endothelial function with Intra-Lipid infusion. We expect that metformin will help preserve the normal function of blood vessels during a fat load. This study will help us understand how fat affects blood vessels and therefore will advance our knowledge of the development of atherosclerosis and potentially lead to improved methods to prevent and treat heart disease.
The vascular endothelium (inner lining of cells in blood vessels) normally prevents vasospasm and thrombosis by producing nitric oxide and other regulatory substances. In patients with atherosclerosis, endothelial function is impaired. Excess production of reactive oxygen species (free radicals) contribute to endothelial dysfunction in atherosclerosis, and some prior studies have shown a beneficial effect of antioxidant treatment on endothelial function in patients with coronary artery disease. On the other hand, reactive oxygen species may be required for normal endothelial function and antioxidant supplements failed to show a benefit in large clinical trials. The effect of antioxidant treatment on endothelial function in healthy subjects is unknown. The present study will test the hypothesis that scavenging reactive species might reduce endothelium-dependent vasodilation in healthy subjects. The study is a randomized, double-blind, placebo-controlled crossover study. Participants will receive 2.4 grams of oral NAC or similar-appearing placebo during the first visit, and then will cross over to the alternative treatment (NAC or placebo) for the second and final visit. We will examine endothelial function before and after treatment on each visit.
The study will assess canagliflozin (JNJ-28431754) in the treatment of patients with type 2 diabetes mellitus (T2DM) with regard to cardiovascular (CV) risk for major adverse cardiac events (MACE). Other objectives include evaluating the overall safety, tolerability, and effectiveness of canagliflozin. The data from this study will be combined with the data from CANVAS-R study (Study of the Effects of Canagliflozin on Renal Endpoints in Adult Subjects with T2DM, NCT01989754) in a pre-specified integrated analysis of CV safety outcomes to satisfy US FDA post-marketing requirements for canagliflozin.
