Filter by:Background: - Heart disease is the leading cause of death in the United States. Eating fruits and vegetables with chemicals called flavonoids may protect against heart disease and improve blood flow to the heart. They are found in blackcurrant berries. Oils found in fish and mussels called omega-3 fats have also been shown to protect the heart. Researchers want to know if blackcurrant extract and omega-3 fats can improve blood flow, which may increase blood to the heart. They also want to learn about the health of blood vessels and how the heart works. Objective: - To learn if blackcurrant extract and omega-3 fats will improve blood flow and make the heart beat stronger. Eligibility: - Healthy adults 55 to 75 years old. Design: - Participants will be screened with medical history, physical exam, and blood tests. - Visit 1 will take 6 7 hours. - Participants will have physical exam and blood and urine tests. - A small device like a microphone will be placed on their arm to take pictures of blood vessels. A blood pressure cuff will be tightened on their arm and more pictures will be taken. - Blood pressure cuffs will be placed on their arms and legs. They will be tightened at the same time and blood pressure will be measured. - Participants will answer questions about their eating and exercise. - Every 8 weeks, participants switch from taking blackcurrant and/or omega-3 tablets to a placebo to no tablets. <TAB> - Every 8 weeks, they will have another shorter clinic visit that will repeat most of visit 1.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in overweight and obese subjects with cardiovascular (CV) disease and/or multiple CV risk factors.
The purpose of this study is to evaluate the quality and prognostic ability of low dose 99mTc-tetrofosmin Myocardial Perfusion SPECT Imaging.
This research focuses on health needs, constructed meanings of health, and meaningful health promotion tactics among women who are heart disease patients. Women with heart disease are considered as a highly vulnerable group for cardiovascular disease-related deaths in Singapore. Because the culture-centered approach has previously demonstrated that community-driven participatory processes of the Culture-Centered Approach (CCA) foster positive changes in health outcomes, this project highlights involvement of community members in developing effective health promotion regarding heart health. Rather than relying solely on interventions created by outside experts, The investigators aim to engage in Heart Health promotion that is meaningful through the involvement of these community members in processes of change. Thus, the investigators seek to engage these women who are heart disease patients in developing a heart health intervention that is beneficial to them. Through in-depth interviews, focus groups, the formation of advisory boards, and community-wide dialogue workshops led by these women, the investigators seek to identify specific heart health promoting strategies and tactics that are meaningful to the lived experiences of the women. As part of the overall solution, this project will work alongside the Women's Heart Health Clinic to create training materials and disseminate findings based on our analysis. Methodology: As far as the methodology, the investigators are using the Culture-Centered Approach (CCA) as well as using biomedical measures for evaluation. First, an advisory board will be formed to inform each step of our methodology and data analysis. First, the investigators will randomize one group of patients into the control group and one group into the experimental group. The investigators will conduct baseline measures for both groups. For the control group, the investigators will measure biomedical data at 3 times (3 months, 6 months, and 12 months). For the experimental group, the investigators will create advisory board that will consist of approx. 4 physicians and 6 patients. In-depth interviews will be conducted with women who have experienced CVD and who live in Singapore. Each interview will last a maximum of 90 minutes. Interviewees will be asked questions about how they understand health, their health experiences, and the obstacles they face in accessing health care in Singapore. Data from the interviews will be analyzed with the advisory board and will be used to guide discussion for the focus groups of women in the experimental group. Focus group sessions, each lasting a maximum of 90 minutes, will be conducted with the patients in the experimental group. In each session, the participants will collectively develop potential solutions for the issues that emerged during the earlier interviews.During the one-year period of study, a participant in the experimental group can participate in one or many of the one-on-one interviews, focus groups, or other activities planned based on the feedback of the participants. Based on the information given in the interviews, advisory board meetings, and focus groups, an intervention will be designed and carried out for the experimental group. This group will also be evaluated at 3 time points (3 months, 6 months, and 12 months) in addition to baseline.
Pomegranate has gained widespread popularity since the health effects of the whole fruit, as well as its juices and extracts, have been studied in relation to a variety of chronic conditions such as hypertension, diabetes, obesity, cancer and cardiovascular disease. The fruit consists of peel, seeds and berries or arils. The peel is rich in minerals and compounds such as polyphenols, but is not an edible part of the plant. In order to harness the benefits of all parts of the fruit, the whole fruit can be crushed and powdered and then easily consumed as pomegranate extract capsules. Pomegranate has been shown to be effective at reducing cardiovascular disease risk factors, particularly with respect to decreasing blood pressure and increasing insulin sensitivity. Dietary polyphenols may also suppress body fat growth. Recently, positive effects on fat reduction have been shown using pomegranate and its extracts. In animal models it has been shown for both extract and leaf that there were significant decrease in food consumption and body weight, inhibiting the development of obesity. In the few human studies, there appeared to be a trend towards a reduction in waist circumference and fat mass, plus a halt in body weight increase, for both juice and seed oil. This parallel, double blinded, randomised, placebo controlled trial aims to confirm previous results concerning the effect of whole pomegranate fruit on biochemical and physiological markers using a new pomegranate extract and to conduct original work to explore its effect on body weight, measurements and fat mass. Any similar interventions have not been double blinded or used pomegranate in extract form. Changes in physiological and biochemical markers will also be investigated. The study hypothesis is that pomegranate extract will reduce BMI and body weight, fat mass, body measurements and blood pressure.
The aim of this study is to determine whether adherence to oral maintenance medications differs for patients randomized to receive a RxTimerCap, a Take-N-Slide, a standard pillbox, or none of these devices, with the hypothesis that low-touch devices improve adherence over control and that the increase in adherence is agnostic across devices.
Ticagrelor therapy has been shown to reduce the rates of cardiovascular events and all-cause mortality compared to clopidogrel therapy in patients with acute coronary syndromes (ACS). The benefit of this study would be to demonstrate that ticagrelor therapy is associated with equivalent platelet inhibition irrespective of the disease status in patients undergoing PCI.
1. To develop a database containing matched information from dynamic tests of postprandial glycemic control (OGTT or MMTT), results of a broad panel of fasting biomarkers, and clinical information related to diabetes risk obtain through subject interview. 2. To use the database to identify fasting biomarkers and associated algorithms to best predict parameters derived from dynamic tests (OGTT or MMTT) such as Insulin Glucose Tolerance (IGT), impaired first phase insulin response, etc., controlling for clinical information such as current medication use.
The Eastern Caribbean Health Outcomes Research Network (ECHORN) is a collaborative research study that examines the lifestyles, eating habits, and health behaviors associated with cancer, diabetes and heart disease in adult men and women living in the Eastern Caribbean.
It is important to identify and evaluate foods, such as strawberries, that can improve established and emerging cardiovascular risk factors, such as postprandial lipid and glycemic responses, and vascular health. Postprandial derangements may affect multiple metabolic pathways that lead to increased arterial stiffness. Research has demonstrated the potential of strawberries to ameliorate postprandial responses to a high fat/high glucose meal. Further research is needed to demonstrate this effect in better controlled clinical studies and explore whether metabolic effects lead to improved arterial health. The investigators propose to examine the effects of adding 40 g of freeze-dried strawberry powder to a high fat/high glucose meal on postprandial cardiovascular risk factor including lipids, insulin, glucose, and arterial stiffness and central blood pressure. The investigators hypothesize that the bioactive components of strawberry powder will attenuate postprandial lipemic and glycemic responses, as well as improve measures of arterial health.
