Filter by:Recent studies suggest that HIV patients are at increased risk for cardiovascular events; however, the mechanisms underlying this increased risk remain unclear. Our group was one of the first to demonstrate that HIV infection is independently associated with accelerated atherosclerosis, as measured by carotid artery-intima media thickness (IMT), and that HIV-associated inflammation may be driving this accelerated atherosclerosis. The mechanism by which HIV disease independent of any drug-specific toxicity increases the risk of cardiovascular disease during HAART is not known. We hypothesize that even well controlled HIV infection is independently associated with cardiovascular risk and that further decreasing HIV-associated inflammation adding newer antiretroviral agents will also decrease cardiovascular risk. We will perform a small clinical trial of approximately 50 HIV-infected patients each to study the relationship between HIV infection, inflammation, thrombosis, atherogenic lipoproteins, and measures of atherosclerosis. We propose the following specific aims: Aim 1: To determine the influence of traditional and novel markers of inflammation on endothelial function and IMT progression; Aim 2: To determine if "intensification" with raltegravir in subjects on long-term antiretroviral therapy with clinically undetectable HIV RNA levels will improve endothelial function, and to determine if this effect is mediated by alterations in inflammatory markers, lipoproteins and/or thrombotic factors. For Aim 2, subjects from 2 randomized, double-blind, placebo-controlled raltegravir intensification studies will be asked to co-enroll in this cardiovascular study.
The purpose of this study is to determine whether PPAR-delta agonist (GW5015156)had favorable effect on lipoprotein metabolism.
The purpose of this study is to determine if whole and fractionated yellow pea flour, administered at USDA recommended dosages (50 g/day), improve risk factors associated with cardiovascular disease and diabetes.
Childhood obesity is a public health problem; in Mexican children a high prevalence of cardiovascular risk factors are present. Physical activity has been proposed as a strategy to reduce this risk. We conducted a pre-posttest intervention study of 214 school-aged Mexican children (4th to 6th grade), to assess the effects of two physical activity routines with different duration and intensity (40 minute aerobic routine vs. 20 minute routine) on cardiovascular risk markers. Physical activity routines were assigned randomly to two public schools in Toluca, Mexico (20 min: group 1 (n= 117), 40 min: group 2 (n=97)). The routines were implemented Monday through Friday for 12 weeks. Nutrition assessment was done before and after the intervention and included anthropometric measurements (weight, height, body mass index, waist circumference and body composition), blood pressure and biochemical analysis (triglycerides, total cholesterol LDL-cholesterol, HDL-Cholesterol, glucose and insulin). Heart rate was monitored 3 times during the intervention to evaluate the routine´s intensity.
The purpose of this study is to better understand why some vein bypass grafts develop narrowing. Evidence suggests that there is a relationship between inflammatory markers in the blood and the narrowing that occurs in blood vessels. In this study, we will look at inflammatory markers in the blood and how well the vein graft functions.
The objective of the Denver Health CVD Prevention Program is to assess the effectiveness of developing an enhanced cardiovascular disease prevention program in a community health care setting.
A concise diabetes self-management education (DSME) program on the "ABCs of Diabetes" will be placed in an urban public library to assess the feasibility of using this community setting for the delivery of health care education in an urban African American population. Impact on knowledge of, prescriptions for, and control of blood sugar (A1C), blood pressure (BP) and LDL cholesterol (LDL-C)before and after participation in the program will be assessed. We will also examine the frequency of emergency department (ED) visits and hospitalizations for uncontrolled diabetes at 6 months post-DSME intervention.
The purpose of this study is to determine whether low and intermediate GI Caribbean foods are effective in the management of type 2 diabetes.
Studies show that depression is a risk factor for the development of coronary artery disease (CAD). Furthermore there is an increased occurrence of depression in patients with CAD. Among other mechanisms atherosclerosis is believed to play a central role regarding these notable associations between depression and CAD. Moreover, patients with late onset major depression have an increased number of small lesions found in the white matter of the brain, the so-called white matter lesions. The main goal of this project is to examine if CAD is associated with depression and/or white matter lesions. CAD is evaluated using coronary CT angiography. Depression is evaluated using a semi-structured diagnostic interview. White matter lesions are quantified using cerebral magnetic resonance.
The goal of this study is to improve cardiovascular disease (CVD) and cholesterol in African Americans adults with diabetes by addressing the modifiable risk factors of systolic blood pressure (SBP), glycosylated hemoglobin (Hb A1c), and low-density lipoprotein cholesterol (LDL-C). We will evaluate the impact of a tailored CVD risk management intervention administered by nurses via the telephone. The intervention incorporates medication management and behavioral modification and will be tailored to the needs of vulnerable high risk subjects (e.g. African Americans, low socioeconomic status, low literate). It will be integrated into community clinics, thereby enhancing the potential for benefit and generalizability to other settings. The primary hypothesis is that among African American subjects with diabetes, a nurse administered, tailored cardiovascular risk management intervention targeting both medication management and behavioral patient self-management will decrease SBP by 5 mmHg, Hb A1c by 0.5%, and LDL-C by 20 mg/dl over 12 months relative to the cardiovascular education-only control group.
