Filter by:To investigate the relationship between obesity, body mass index (BMI) rebound, body composition changes, associated factors (e.g., diet, physical activity), and cardiovascular risk factor status in a longitudinal study of young children, age three at the beginning of the study.
The BARI 2D trial is a multicenter study that uses a 2x2 factorial design, with 2400 patients being assigned at random to initial elective revascularization with aggressive medical therapy or aggressive medical therapy alone with equal probability, and simultaneously being assigned at random to an insulin providing or insulin sensitizing strategy of glycemic control (with a target value for HbA1c of less than 7.0% for all patients). SPECIFIC AIMS A. Primary Aim The primary aim of the BARI 2D trial is to test the following two hypotheses of treatment efficacy in 2400 patients with Type 2 diabetes mellitus and documented stable CAD, in the setting of uniform glycemic control and intensive management of all other risk factors including dyslipidemia, hypertension, smoking, and obesity: 1. Coronary Revascularization Hypothesis: a strategy of initial elective revascularization of choice (surgical or catheter-based) combined with aggressive medical therapy results in lower 5-year mortality compared to a strategy of aggressive medical therapy alone; 2. Method of Glycemic Control Hypothesis: with a target HbA1c level of less than 7.0%, a strategy of hyperglycemia management directed at insulin sensitization results in lower 5-year mortality compared to a strategy of insulin provision. B. Secondary Aims The secondary aims of the BARI 2D trial include: a) comparing the death, myocardial infarction or stroke combined endpoint event rate between the revascularization versus medical therapy groups and between the insulin sensitization versus insulin provision groups; b) comparing rates of myocardial infarction, other ischemic events, angina and quality of life associated with each revascularization and hyperglycemia management strategy; c) evaluating the relative economic costs associated with the trial treatment strategies, d) exploring the effect of glycemic control strategy on the progression and mechanism of vasculopathy including changes in PAI-1 gene expression.
To investigate whether traditional risk factors and novel risk factors predict higher risk of atherosclerotic cardiovascular disease (ASCVD) in a prospective study of incident dialysis patients.
To assess in four large Chicago population cohorts whether young adult and middle-aged risk factor status has an impact not only on average annual Medicare costs, but also on cumulative and lifetime Medicare costs, to ages 70, 75, 80, >80, including to death, and during the last one to two years of life.
To study the genetic cause of low HDL-C, a risk factor for premature atherosclerotic vascular disease in patients with normal total cholesterol. The focus is primarily on the identification of a single mutation, as has been demonstrated in one family.
To examine whether the association between selected hypertensive genes and combined fatal coronary heart disease and nonfatal myocardial infarction in high-risk hypertensives is modified by the type of antihypertensive treatment, leading to differential risks of coronary heart disease.
To document cardiovascular disease and cardiovascular disease risk factors among 1,200 Native Alaskans who are members of approximately 40 families.
The purpose of this study is to compare the effects of diluted hematocrit (HCT) levels of 35% versus 25% during hypothermic cardiopulmonary bypass (CPB) in infants with d-transposition of the great arteries, a malformation of the heart vessels.
Promoting Healthy Lifestyles: Alternative Models' Effects (PHLAME) is a research study to evaluate and compare two ways to promote healthy behaviors, (regular physical activity, less than 30% calories from fat, 5 or more servings of fruits plus vegetables each day and maintain a healthy weight). Unhealthy nutrition practices and sedentary (inactive) lifestyles are the two most common harmful behaviors in the United States. Our two health promotion methods are 1) a team-based approach and 2) a one-on-one approach involving meetings with a health counselor. A third group only receives the same evaluation and their results and is the control group. Study participants are firefighters from 36 fire stations in Oregon and Washington. The goals of the study are increased physical activity and fitness, improved nutrition, and improved energy balance (reduced body fat). Changes in these factors can help lower risks for heart disease, some types of cancer, diabetes, hypertension and musculoskeletal injuries. Results from PHLAME will provide information on how best to help adults achieve and maintain healthy lifestyles.
To coordinate an international study on the relationships between population mean sodium and potassium intake and blood pressure.
