Filter by:The primary objective of the double-blind segment is to compare effects of alagebrium vs placebo on change from baseline in endothelial function, as assessed by flow-mediated vasodilation (FMD).
Diet has long been used as a way to provide enough nutrients to an individual in order to meet metabolic requirements. However, recent scientific advancements have suggested that beyond meeting nutrition needs, diet may also be health promoting through the modulation of various body functions. In a way, the role of nutrition has evolved from hunger satisfaction and maintenance of body integrity to the promotion of a state of well-being and prevention of important chronic diseases such as cancer, diabetes and cardiovascular disease (CVD). In recent years, n-3 polyunsaturated fatty acids (PUFA) have attracted much attention as consumption of a n-3 PUFA rich diet has been reported to reduce CVD risk. However, n-3 PUFA are also highly susceptible to free radical damage and therefore could be unable to fully exert their health benefits under an oxidative stress condition. The general objective of the present application is to investigate the mechanisms by which n-3 PUFA improve cardiovascular health in abdominal obesity and explore the potential of dietary antioxidants to modulate these effects in individuals at high risk of oxidative stress. For that purpose, we plan to study the changes in fasting and postprandial plasma lipoprotein-lipid levels, markers of lipid and lipoprotein oxidation, inflammation and endothelial dysfunction following 12 weeks of n-3 PUFA supplementation with or without low-calorie cranberry juice cocktail (as a source of antioxidants) in a group of 160 men. We feel that the present study will broaden our understanding of the physiological mechanisms underlying the beneficial effects of consuming unsaturated fatty acids and give further insights on the role of antioxidants in preserving and potentiating these cardiovascular health benefits.
Physical inactivity is a major public health problem in the United States. Research has shown that physical activity levels decline during adolescence, and the decline is greater in females than males. The purpose of this study is to evaluate a life-skills oriented physical activity intervention at increasing activity levels and decreasing cardiovascular risk factors in adolescent females.
The purpose of this study is to investigate the effect of intake of Omacor (Omega-3-acid ethyl ester 90) 2g/day on specified parameters related to the stability of carotid plaque in patients awaiting endarterectomy.
The purpose of this study is to demonstrate the benefit of MVP in pacemaker and implantable cardioverter defibrillator (ICD) patients with a history of right ventricular pacing.
Patients with kidney failure have a poor survival rate that is due to a much higher than average rate of heart and vascular disease. The reason that kidney failure causes heart disease is unknown but recent research suggests that a hormone called aldosterone, which is increased in patients with kidney disease may damage the heart and blood vessels. The investigators propose, using a randomized blinded trial, to find out whether drugs that inhibit the actions of aldosterone have beneficial effects on the cardiovascular system in patients with kidney failure
The overall aim of the study was to test the feasibility and effectiveness of a cardiovascular disease risk reduction intervention program for midlife, low-income women. We enhanced an existing nutrition and physical activity intervention tool, A New Leaf...Choices for Healthy Living, which was designed specifically for this demographic group as part of the CDC's WISEWOMAN Program. The enhanced intervention was tested in a randomized controlled trial in a community health center setting.
This study investigates treatment effects from aerobic endurance training, maximal strength training and computer game on aerobic capacity, work efficiency and psychiatric symptoms in patients suffering from schizophrenia. The study is a controlled trial. The aim is to describe the population in respect to aerobic capacity and muscular strength. Low aerobic capacity and muscular strength are important risk factors for cardiovascular disease (CVD). The study also aim to evaluate physical and psychiatric effects from physical training. Effects from participation in physical training or computer game on symptoms, depression and quality of life will be investigated. Data will be collected between October 2005 and August 2007.
Moderate alcohol consumption is associated with a decreased risk of cardiovascular disease and type 2 diabetes. The association of alcohol consumption with cardiovascular disease is mediated by a functional polymorphism of alcohol dehydrogenase 1c, but the effect of this polymorphism on alcohol metabolism is only investigated in vitro. The risk reduction of moderate alcohol consumption for cardiovascular disease is explained largely by an increase of HDL cholesterol, but an increase of adiponectin concentrations after moderate alcohol consumption may also be involved. It seems likely that adiponectin is a mediator for the association of moderate alcohol consumption with type 2 diabetes. The mechanism by which moderate alcohol consumption increases adiponectin concentrations is unknown, but ppar-gamma activation may be involved. effects of this polymorphism on mediators of this relation are not known. This study therefore investigates the effect of moderate alcohol consumption and the influence of alcohol dehydrogenase 1c polymorphism on ppar-gamma activated gene expression and risk factors of cardiovascular disease and type 2 diabetes.
