Filter by:The purpose of this study is to compare the effects of a low-carbohydrate diet and a high-carbohydrate, high-fiber diet, on insulin sensitivity and blood chemicals considered risk markers for heart disease, in persons with the metabolic syndrome. Our primary hypothesis is that the ad libitum high-carbohydrate, high-fiber diet will significantly improve insulin sensitivity, whereas the ad libitum low-carbohydrate, low-fiber diet will not.
The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be significantly associated to muscle mass gain.
Study Objective: 1. To evaluate whether combined therapy with folic acid 2.5 mg/day, vitamin B6 50 mg/day and vitamin B12 1000 micrograms/day vs placebo reduces the rate of atherosclerosis progression, as evaluated by quantitative B-mode carotid ultrasound (US).
The primary focus of this study is to collect information through diagnostic testing, blood sample analysis and patient data collection on patients starting hemodialysis to determine risk and preventative factors of bleeding and clotting events.
This Western Pennsylvania-based study will (1) improve cardiovascular risk stratification to identify high-risk populations, (2) identify disparities in cardiovascular risk based on race, socioeconomic status, and geographic location, (3) evaluate mechanisms for population differences in cardiovascular risk, and (4) implement a multidisciplinary community-based intervention program to decrease cardiovascular risk in high-risk populations. These goals, which are designed to eliminate ethnic and racial health disparities, are closely tied to the National Initiative to Eliminate Racial and Ethnic Disparities in Health and the nation's health promotion and disease prevention agenda established in Healthy People 2010. This is a prospective cohort study of 2,000 residents of the state of Pennsylvania with approximately equal representation of white and African American subjects. All participants will undergo assessments of traditional and nontraditional risk factors to identify and determine the mechanisms of population disparities in cardiovascular risk. 800 participants who are at intermediate or high risk of cardiovascular disease will be randomly assigned to either (1) usual care/"advice only"; or (2) a multidisciplinary behavioral modification program to determine the most effective approach to reduce or eliminate racial, socioeconomic and geographic disparities in cardiovascular risk. All participants will undergo long-term follow-up for cardiovascular events.
The purpose of this study is to compare the effectiveness of aortic stent surgery versus exercise therapy in individuals with aortoiliac insufficiency.
The purpose of this study is to evaluate whether the addition of warfarin (a blood-thinning medication) to an antiplatelet therapy like aspirin is better than antiplatelet therapy alone (i.e. usual treatment) for the prevention of leg surgery, heart attacks, stroke and death in people with peripheral vascular disease.
The purpose of this study is to compare an angiotensin II receptor antagonist (candesartan cilexetil– Blopress®) and a calcium channel blocker (amlodipine besilate– Norvasc®/Amlodin®) in terms of the incidence of cardiovascular events among high-risk hypertensive patients.
There is evidence linking cardiopulmonary bypass to negative side effects when used for coronary artery bypass grafting. Coronary artery bypass grafting can be performed without the use of cardiopulmonary bypass. The purpose of this study is to determine the positive and negative effects of coronary artery bypass grafting with or without the use of cardiopulmonary bypass. The patients will be followed at least one year after surgery.
The purpose of the HOPE-2 study is to determine whether long term supplementation with folic acid, vitamins B6 and B12 aimed at homocyst(e)ine reduction reduces the rates of major fatal and nonfatal cardiovascular events in patients with established cardiovascular disease and/or diabetes mellitus.
