Filter by:The overall objective of this research proposal is to determine whether the predictive value of using plasma concentrations of selected nutrient biomarkers of food intake determined using a single plasma sample either alone or in combination are stronger, objective predictors of subsequent death from coronary heart disease (CHD) or myocardial infarct (MI) compared to selected food intake data derived from subjective, self-reported food frequency questionnaires.
The association between alcohol consumption and cardiovascular disease (CVD) has mostly been examined using broad endpoints or cause-specific mortality. The purpose of our study is to compare the effect of alcohol consumption in the aetiology of a range of cardiovascular disease phenotypes.
The purpose of this study is to determine the effectiveness of a program to improve habits in a population with cardiovascular disease, comparing two different educational techniques (cognitive behavioral therapy group vs. informational workshops).
The hypothesis of this study is that the natural supplement Capros will decrease LDL levels, platelet aggregation, and serum concentrations of high sensitivity C-reactive protein in humans at risk for cardiovascular disease.
The objective of this study is to formulate and validate a green tea confection (i.e. "gummy" candy) as a strategy to attenuate postprandial hyperglycemia-induced impairments in vascular function. The central hypothesis is that a green tea confection will protect against vascular endothelial dysfunction by suppressing postprandial hyperglycemia. The central hypothesis of this application will be assessed by developing a green tea-containing confection, examining its physiochemical properties and its inhibition of starch digestion, and then validating its vasoprotective activities in healthy humans by assessing its blood glucose-regulating activities.
The purpose of this study is to determine the effects of individual characteristics, life stresses, and relationships over time on psychosocial outcomes (e.g. marriage, parenting, work) and physical health
The purpose of this study is to document differences between men and women (referred here as gender differences) in diet adherence and in changes in specific dietary intakes and energy density in response to a 12-week nutritional education program promoting the Mediterranean diet in both the short term (immediately after the end of the intervention) and longer term (3 and 6 months after the end of the intervention). The investigators hypothesize that both in the short and the longer term, women will have a better adherence to recommendations promoting the Mediterranean diet than men namely because of higher self-determination.
The purpose of VIPVIZA is to assess the impact of pictorial information about asymptomatic atherosclerotic disease to both physician and patient, for improving physicians' adherence to prevention guidelines and patient perception and understanding of the cardiovascular disease (CVD) risk and consequent motivation for prevention. The intervention effect is assessed by differences between randomization groups in the primaryboutcome Framingham Risk Score (FRS) and the secondary outcomes the Systematic COronary Risk Evaluation (SCORE) as well as changes in these scores after one, three and six years. Secondary outcomes are also atherosclerotic disease progression, as assessed by repeated carotid ultrasound examination after three and six years, as well as the prevalence of acute events and mortality after 10 years . Social, psychological and cognitive determinants of behavioral change as well as the intervention impact on novel biomarkers will also be explored.
Coronary artery bypass grafting (CABG) using the radial artery (RA) has since the nineties gone through a revival. The initially reported worse outcome in RA graft patients compared to patients grafted with the saphenous vein (SV) has since been corrected. Studies have shown better patency when using RA, so the RA is going to be preferred more and more especially in younger patients where long time patency is critical. During the last 10 years endoscopic techniques to harvest the RA have evolved. Multiple different techniques have been used, but now the equipment and technique have been refined and are highly reliable. The investigators hypothesize that the endoscopic technique has less complications and a just as good patency as open harvest. There are also two possible ways to use the RA as a graft. One way is sewing it onto the aorta and another way is sewing it onto the mammarian artery. The investigators hypothesize that using it on the mammarian artery is superior as a revascularisation technique with just as good a patency as sewing it directly onto the aorta.
Data from both the traditional invasive cardiac monitors and the Nonin will be collected simultaneously. The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to look for correlations in clinically important parameters such as blood pressure, central venous pressure, cardiac output, etc.
