Filter by:The purpose of this study is to assess the distribution, awareness and control of main cardiovascular risk factors in the Spanish population. The main study variables are: - Lifestyles (tobacco, alcohol, nutrition, physical activity) - Biological risk factors either well-established (blood lipids, glucose, insulin and blood pressure) or emergent (leptin, C-reactive protein and other markers of inflammation)
Background: - Cardiovascular disease (CVD) is a leading cause of death in developed countries. Although statin-type drugs are currently the most effective therapeutic agents for reducing CVD risk. One possible complementary approach involves the use of soluble dietary fibers that are known to reduce blood cholesterol levels. However, analysis has shown that most soluble fibers reduce total cholesterol levels by relatively small amounts. - Alpha-Cyclodextrin (Alpha-CD), also sold in commerical form, is a soluble fiber derived from corn that is used as an ingredient in many foods, such as bread rolls, crackers, juices, and reduced fat spreads. It is added to food primarily as a fiber supplement but is also used to stabilize flavors, colors, vitamins, and fatty acids. Studies in animals and humans have shown that Alpha-CD may help to improve insulin resistance and lower LDL cholesterol levels with no apparent side effects. More research is needed to determine the effect of Alpha-CD on total cholesterol levels in healthy volunteers. Objectives: - To determine the effect of oral Alpha-CD on total cholesterol in a nondiabetic population.
Background: Hypertension (HTN) is a major risk factor for cardiovascular disease (CVD), the leading cause of death in the United States and New York City (NYC). One in 4 NYC adults has hypertension, with higher prevalence in both Blacks and Latinos compared to Whites (Angell 2008). In NYC, only 65% of all adults with HTN and on treatment are controlled (Angell 2008). Self-blood pressure monitoring (SBPM) is associated with reduced blood pressure in patients with hypertension (Cappuccio 2004). Studies suggest that SBPM may increase control either by inducing clinicians to titrate medication more actively, (Agency for Healthcare Research and Quality 2002) by engaging patients to participate in their own health care, (Taylor 2007) or a combination of the two. However, minimal research has been done to evaluate the effectiveness of SBPM in different racial and/or ethnic groups or in low income populations or to discern effective patterns of SBPM use by patients. Best practices for integration of self monitoring into HTN into regular treatment have also yet to be established. Objectives: The goal of this study is to assess the impact of SBPM under conditions consistent with existing community health clinic resources and infrastructure in NYC's medically underserved neighborhoods using commonly available automated home BP monitors. By using a community clinic's electronic health record (EHR) and automated BP monitors with the capability to transmit readings to a research database, we can facilitate a more rigorous evaluation of a pilot SBPM intervention and assess patterns of home monitor use and clinical management and their association with outcomes. The three specific aims of this intervention are to: 1. Assess whether use of SBPM reduces elevated BP and increases HTN control to similar levels in two historically understudied minority populations, Blacks and Latinos. 2. Confirm pilot findings by assessing the impact of SBPM on BP and HTN control compared to usual care using randomized controlled trial methodology. 3. Develop standards and refine guidance for the effective use of SBPM that can be easily communicated to key stakeholders.
Because of increased life expectancy and improved therapeutic methods in cardiology, the proportion of very old patients with cardiovascular disease increases. However, clinical practice "in real life" are still insufficiently known in this population. The recommendations still lack of studies specifically devoted to elderly or very elderly, an extrapolation of data based on evidence obtained in younger populations. This is a multicenter observational study during a day. On this day, all participating centers fill a questionnaire for each patient 80 years or older hospitalized in their service.
The aim of this study is to examine the effects of a diet rich in broccoli on cardiovascular disease risk using biochemical indicators such as blood lipid profiles, most notably cholesterol; markers of inflammation as well as established physiological measurements such as Pulse wave velocity (PWV), Augmentation index (AIx) and Ambulatory Blood Pressure Measurements (ABPM). Broccoli contains compounds known as glucosinolates which are metabolised to isothiocyanates when consumed. The major glucosinolate in broccoli is known as glucoraphanin which produces the isothiocyanate sulforaphane. The glucosinolates are thought to be the principal component in broccoli that may reduce CVD risk. The investigators will use a standard cultivar of broccoli and a cultivar that has enhanced levels of glucosinolates ('HG broccoli'). This broccoli has been used in previous intervention studies (e.g. ClinicalTrials.gov NCT00535977). Volunteers will be asked to consume 400g of standard broccoli, HG broccoli or peas each week over a 12 week period in a double blinded (for the broccoli) parallel study. The volunteers recruited will, according to the Joint British Societies (JBS 2) Guidelines on the prevention of cardiovascular disease (CVD) in clinical practise, have a 10-20% (mild to moderate) risk of developing cardiovascular disease or having a cardiovascular (CV) event in the next 10 years.
The purpose of this study is to compare the radiation exposure of a variety of chest CT examinations performed on the current state of the art CT scanners (64 slice, dual source CT scanner) with the radiation exposure for identical chest CT examinations performed on the Siemens Flash CT scanner (high pitch dual source spiral technique).
The purpose of this study is to evaluate the Efficacy and Safety of Dehypotin® in the Patients with Type 2 Diabetes Mellitus or Cardiovascular Disease. Eligible patients will be randomly assigned to 1 of 2 arms, either Dehypotin® or placebo, and will receive the diet advisement throughout the study.
The investigators hypothesize that cLDL levels are elevated in RA patients and represents an important mechanism for accelerated atherosclerosis leading to excess cardiovascular disease (CVD) in rheumatoid arthritis (RA) patients. The purpose of this study is to improve understanding of the reasons for increased cardiovascular diseases (such as heart attack and stroke) seen in patients with rheumatoid arthritis (RA, an arthritis that causes inflammation and destruction of joints). Specifically, the study plans to determine whether a particular type of change in proteins in LDL cholesterol ("bad cholesterol") known as carbamylation is an important risk factor for cardiovascular diseases in RA patients. The study will utilize a case−control study design. A total of 120 subjects (males and females between the ages of 18 and 80) may be enrolled in order to ensure that 100 subjects (50 RA case subjects and 50 age and sex matched controls) complete the study. Procedures will consist of a single visit for each subject during which a screening evaluation, an enrollment evaluation, and a single blood draw will be performed.
Childhood obesity has increased in prevalence over the past several decades and is predictive of adult type 2 diabetes and cardiovascular disease (CVD). Recent studies of children and youth suggest that exercise reduces cardiometabolic risk factors. Minimal data are available, however, on the effects of "exergaming" , interactive technology- mediated approaches to increasing physical activity in children and youth. This project involves a partnership between UMass Boston/GoKids Boston and Children's Hospital Boston featuring an interdisciplinary team of researchers and clinicians from pediatric cardiology, nursing, prevention and behavioral sciences and exercise physiology and is designed to examine the effects of exergaming on moderate or vigorous physical activity (MVPA) indices of adiposity, risk factors for cardiometabolic disease and self-competence in Boston Public School children. It is hypothesized that participation in the EXCEL/exergaming intervention for 60 minutes, three times per week for 12 weeks will significantly increase MVPA (as measured by accelerometers), pre- to- post intervention and compared to an Advice only (Nutrition Education) group.Results of this pilot study will guide and inform a larger study of exergaming in children from the Boston Public Schools.
The purpose of the study is to examine the effect of plant sterols on cholesterol absorption and synthesis in people with heterozygous phytosterolemia.
