Filter by:There will be no significant decrease in the use of low dose acetylsalicylic acid (ASA) therapy for primary prevention across the three intervention arms from baseline to completion of the project. There will be no significant differences in the percentage of patients with diabetes mellitus greater than 44 years of age on low dose ASA therapy for primary prevention across the three arms of the study using repeated measures from baseline to completion of the project.
Cardiovascular disease (CVD), including heart disease and stroke, is the leading cause of death in the US. Every year, more than one million Americans have a heart attack, and nearly 800,000 have a stroke. In 2010, heart disease alone is expected to cost the country more than $316 billion in health care and lost productivity. Both lifestyle changes and medication can reduce the risk of CVD, and this project combines these approaches in the hopes of identifying a practical intervention for use in primary care medical offices. The project combines two previously tested interventions and updates them to meet current guidelines for diet and use of aspirin and cholesterol-controlling drugs (statins). The research team is delivering the combined intervention in two formats: web-based and counselor-based. Each format has the same content, but the web-based advice is accessed through the Internet by clients at home, a community site, or a primary care office. The other format involves sessions delivered to clients by a counselor either in person at a primary care office or over the telephone. The researchers will compare how effective each format is in reducing participants' risk of coronary heart disease. They will also determine the interventions' effect on participants' diet, physical activity, smoking status, medication adherence, and other health indicators. In addition, the team will compare the two formats' cost-effectiveness and how well the patients, office staff, and clinicians accept the interventions. Recruited from five family practices, 600 patients representing the geographic and ethnic diversity of North Carolina are taking part in this study. Half the participants are randomly assigned to the web-based intervention; the other half to the counselor-based version. Both groups will also get information on local resources, such as gyms and farmers markets, that can help participants maintain a healthy lifestyle.
People report feeling sad and low (depression) or worried (anxiety) appear more likely to subsequently suffer a heart attack, or angina. However it is not known whether depression or anxiety actually causes heart disease. If these mental health problems and heart disease were cause and effect this has important implications for world health. Previous research on this topic has had several limitations. First, most studies have studied heart disease as if it were one thing. There is a need for studies which distinguish different types of heart disease (e.g. different types of heart attack, angina) which may be linked to mental health problems in different ways. Second, it is not clear whether symptoms of heart disease come before the depression or anxiety or the other way round? Much of the available research cannot look at this in detail because they rely on data from occasional snapshots of study populations rather than a continuous record. The investigators propose to use the linkage of the national registry of coronary events to general practice records in the GPRD, which will allow us to address these limitations. The investigators research will help us understand better whether mental health problems cause the onset of different types of coronary disease.
The hypothesis is that switching calcium based phosphate binders to sevelamer carbonate will be associated with less inflammation including less atherosclerotic plaque inflammation (inflammation of the vessel walls).
The purpose of this study is to determine whether L5, one of the Low Density Lipoproteins, is an effective predicting factor for cardiovascular disease in chronic renal and hemodialytic patients.
The investigators propose to evaluate the effects of avocado consumption (by incorporating 1 unit of fruit per day into a healthy diet) on multiple cardiovascular disease (CVD) risk factors. The investigators will compare chronic consumption of a moderate fat blood cholesterol-lowering diet incorporating one avocado per day versus a blood cholesterol-lowering Lower-Fat diet on established CVD risk factors including lipids and lipoproteins, and blood pressure (BP). The investigators also will evaluate the effects of an avocado diet on several emerging CVD risk factors. To elucidate the specific benefits of avocado and its accompanying bioactives on the aforementioned risk factors, the investigators will compare the avocado diet with a diet that has the same macronutrient profile (but without the avocado).
Cardiovascular disease is a major cause of mortality worldwide resulting in one out of three global deaths. One of the main characteristics of cardiovascular disease is impaired blood flow and increased formation of clots. Platelets are clot-forming cells responsible for prevention of bleeding. However, in disease state they may be overly activated and tend to stick to each other, promoting blood clots and blockage of vessels. Conjugated linoleic acids (CLA) are unique fatty acids present in dairy food products and beef which would help to prevent platelets from clotting and thus help to prevent cardiovascular disease. However, the mechanisms by which those fatty acids affect platelet function are not yet fully understood. We designed a human intervention study assessing the mechanisms by which CLA beneficially affect platelet function and markers of haemostasis and inflammation in humans.
An abdominal aortic aneurysm (AAA) is a weakened and enlarged area in the abdominal aorta, which is a large blood vessel in the abdomen. Large AAAs (>55 mm diameter) carry a high risk of rupture, a surgical emergency that often leads to death due to severe internal bleeding. It has been suggested that regular exercise training might limit the rate at which AAAs develop. However, little is known about the safety and effectiveness of exercise training in these patients. This pilot study will examine the feasibility of supervised aerobic exercise training for patients with small AAAs (30 to 49 mm diameter). The investigators hypothesize that exercise training will be safe and useful for patients with small AAAs.
The objectives of this study are to examine how the consumption of treatment oils (including canola oil, DHA enriched canola-oil, high oleic acid canola oil, flax oil, and safflower oil) influence endothelial function, inflammation, oxidation, body composition, and plasma lipoprotein characterization.
The trial will test whether the Alive email-delivered health behavior program can improve subjects' physical activity, fruits and vegetables and saturated/trans fats and added sugars.
