Filter by: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.
The project aims to examine the efficacy of a 12-week intake of alginate based ready to drink supplement on development in body weight and body composition, and risk markers for type-2 diabetes and cardiovascular disease in obese subjects.
This is a multi-center trial that will evaluate the safety, feasibility, and cost effectiveness of discharging patients, who have had successful percutaneous coronary intervention (PCI) and deployment of the AngiomaxTM closure device, 6 hours after against 24 hours after the procedure. Patients will be randomized in a 3 (test): 1 (control) fashion and will have a study population of 600 patients over 6 investigational sites all within the United States. Patients <65 years old will be chosen in order to stay within the low risk group and will be followed up after 24 hours, 7 days, and 30 days via phone or office visit. The primary endpoint will be a composite of major adverse cardiac and cerebral events, and the incidence of major bleeding or vascular complications. Data acquired from the study, such as blinded financial information and patient satisfaction surveys, will be used in order to evaluate cost analysis and safety of the procedure.
Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide synthesis in endothelial cells as caveolin-1 helps to spatially organize eNOS in close proximity to signaling proteins that are important for eNOS activation. In certain diseases however, the balance of caveolin-1 and eNOS can be disrupted resulting in impaired nitric oxide synthesis and leading to endothelial dysfunction. The investigators therefore seek to characterize levels of caveolin-1, and correlate this with the presence or absence of sleep disordered breathing, obesity, and cardiovascular disease. The current IRB protocol covers the performance of fat biopsies on subjects who have recently completed a sleep study either in the Center for Sleep Medicine or in our sleep laboratory and were found to have sleep disordered breathing or no sleep disordered breathing, subject with sleep disordered breathing who have been treated successfully with continuous positive airway pressure for 3-6 months, and subjects undergoing other studies in our lab who are obese or non-obese and subjects who have known cardiovascular disease and subjects without known cardiovascular disease.
Cardiovascular Diseases (CVD) according to the World Health Organization (WHO) are leading causes of death and represent 30% of all global deaths and 48% of the deaths in Europe. Moreover, the current trends predict increase in deaths caused by Cardiovascular Diseases over the next years. Secondary preventive efforts can decrease mortality risk as well as improve health among Cardiovascular Disease patients. This study suggests an innovative approach in supporting the self-management of Cardiovascular Disease patients after rehabilitation. The implied Randomized Controlled Trial has two arms and aims to investigate the effectiveness of tailoring in an Information and Communication Technology (ICT) based intervention. The tailoring will be based on concepts derived from health psychology theories, and will contribute in their further development. More specifically: - Aim 1: To assess the needs of CVD rehabilitation patients that can potentially be met through the use of ICT. - Aim 2: To assess the effects of a tailored Internet-based intervention on maintenance of self-management behaviors after a rehabilitation stay. Hypothesis: The intervention group (tailored) will have higher adherence a) to the Internet-based intervention, and b) to self-management. - Aim 3: To assess the effect of mobile technology with activity sensors on physical activity. Hypothesis: There will be a relationship between the data collected from activity sensors and the self-reported physical activity levels.
Type 1 diabetes mellitus (T1DM) is associated with multiple co-morbidities, such as hypertension, dyslipidemia, coronary heart disease and osteoporosis. The foundation of these conditions lays in childhood. Exercise is known to have a positive influence on bone mineral density (BMD) and some impact on cardiovascular disease risk factors in healthy children, but little is known about these associations in children with T1DM. The main purpose of this study is to assess the effects of a 9-month weight-bearing exercise training program on skeletal development in children with T1DM, compared to healthy subjects. The second aim is to evaluate whether the program influences also cardiovascular diseases risk factors. This is a randomized controlled study incorporating 30 children with T1DM and 30 healthy children. Both groups are randomly divided (1:1) in an exercise or a control group: 1) exercise diabetic, 2) controls diabetic, 3) exercise healthy, 4) controls healthy. Exercise groups participate to an identical weight-bearing exercise training program 2 x 90 minutes per week and controls are relatively inactive. Main measures include: total body, lumbar spine and hip BMD by DXA, body fat and fat-free mass, bone biomarkers levels, resting and ambulatory blood pressure and fasting blood lipids.
In this multicentre Randomized Clinical Trial, the heparin-bonded endoluminal bypass will be compared to the surgical venous femoro-popliteal bypass, based on the non-inferiority principle for the patency. Besides equal patency, an improved quality of life is expected. Recruitment will take the first two years and patients will be followed during five years. Patients with an indication for surgical bypass, classified category 3-6 with a >50% stenosis or occlusion of the SFA over >/=10 cm in length will be included. At least one crural artery should be patent without significant lesions.
The purpose of this study was to examine the effect of 6 months moderate intensity exercise training completed three times per week upon traditional and emerging cardiovascular disease risk factors in postmenopausal women both with and without type 2 diabetes. These risk factors include blood markers associated with increased risk such as cholesterol, insulin, glucose and markers of inflammation plus measures of body fat, heart and lung fitness, vascular stiffness and vascular function. The study hypothesised that moderate intensity exercise training would intervene in the exaggerated risk seen in women following the menopause, especially in those with type 2 diabetes.
