Filter by:The purpose of this research is to build the evidence base for approval of FDA health claims related to almonds and cardiovascular disease. A randomized, 2-period, crossover controlled feeding study was designed to compare the effects of two blood cholesterol lowering diets that meet the American Heart Association recommendations. The nutrient profiles of the control diet (no almonds/day) and almond diet (1.5 oz. of almonds/day) are matched for protein, saturated fat, and cholesterol. The study population consists of two cohorts of 25 men and women with moderately elevated LDL-C. The investigators hypothesize that a cholesterol-lowering diet designed with almonds confers greater cardioprotective effects than a cholesterol-lowering diet without almonds on the basis of the LDL-C lowering response, effect on LDL particle size, abdominal adiposity and vascular health.
The purpose of this study is to see whether subjects with gout who receive febuxostat or allopurinol for up to 9 years have a higher rate of serious heart and blood vessel complications (major cardiovascular events).
Cardiovascular disease is a major cause of mortality worldwide and responsible for one out of three global deaths. A main characteristic of cardiovascular disease is impaired blood flow and formation of blood clots. Platelets are clot-forming cells responsible for the prevention of bleeding. However, in disease conditions they may be overly activated, promoting blood clots and blockage of blood vessels. Consumption of diets rich in fruits and vegetables decreases mortality from cardiovascular disease through a number of mechanisms, including the prevention of platelet clotting and aggregation. There is some evidence suggesting that platelet aggregation may be modulated through a group of compounds known as flavan-3-ols, which are found in various foods, and especially in cocoa. However, the mechanisms by which those compounds affect platelet function are not yet fully understood. We designed a human study assessing the mechanisms by which flavan-3-ols from cocoa beneficially affect platelet function and the platelet proteome.
The overall aim of Healthy Bodies, Healthy Hearts research study is to promote physical activity in women aged 45-65 years to promote reduced risk of cardiovascular disease. The investigators are conducting an intervention for 12 weeks that promotes physical activity through support groups, group exercise sessions or through information that is given at the baseline appointment. Participants will be randomly assigned to a group.
Background: - Antiretroviral therapy has increased the lifespan of people with human immunodeficiency virus (HIV), but recent research suggests that people with HIV also have an increased risk of developing cardiovascular disease. To better understand the prevalence and effects of heart disease in people with HIV, researchers are interested in comparing heart imaging and metabolism studies to see if there are differences between HIV-positive and HIV-negative people. Objectives: - To study metabolism and heart function in people with HIV compared with healthy HIV-negative volunteers. Eligibility: - Individuals at least 18 years of age who either have been diagnosed with HIV or are healthy HIV-negative volunteers. Design: - Participants will be evaluated with a physical exam, detailed medical history, and routine blood and urine tests including HIV testing. - Participants will have the following imaging scans: - Cardiac magnetic resonance imaging (MRI) to study the health of the heart and blood vessels - Magnetic resonance spectroscopy (MRS) of the heart, liver, and skeletal muscle - Cardiac computerized tomography (CT) scan to measure calcium levels in the heart and nearby arteries - Dual-energy x-ray absorptiometry (DEXA) scan to measure body fat and muscle mass. - Stable isotope infusion to evaluate how the body processes fat (which will require an overnight stay before the test) - Participants will also have blood tests, an echocardiogram, and an electrocardiogram to evaluate heart function.
The purpose of this study is to determine whether a dietary pattern based on crononutrition and dietary training, together with dietary and psychological control, can reduce the body weight, improve the oxidative and inflammatory state in subjects with diagnosed metabolic syndrome features and can reduce the prevalence of the Metabolic syndrome in the population.
This study examines the role of sleep apnea treatment in improving cardiovascular biomarkers.
Major surgeries not involving the heart are common, and major heart problems during or after such surgeries represent a large population health problem. Few treatments to prevent heart problems around the time of surgery have been tested. There is encouraging data suggesting that small doses of Acetyl-Salicylic Acid (ASA) and Clonidine, which are two medications, given individually for a short period before and after major surgeries may prevent major heart problems. The POISE-2 Trial is a large international study to test if ASA and Clonidine can prevent heart attacks and deaths from heart problems around the time of surgery.
The purpose of this study is to determine the lowest effective dose of EPA + DHA (300, 600, 900 and 1,800 mg/day delivered as fish oil supplements) that significantly attenuates the inflammatory response to in vivo and ex vivo endotoxin challenge as measured by the production over time of several inflammatory markers.
The advent of new antiretroviral drugs improved the management of HIV naive patients in terms of efficacy. However, the long term metabolic profile of this drugs has not yet been compared and associations between new antiretrovirals and cardiovascular events remains controversial. Moreover, the better tolerability and easy dosage of this new drugs might hypothetically influence adherence and QOL of HIV patients.
