Filter by:Current dietary recommendations suggest that lowering intake of saturated fats or replacing it with unsaturated fats will decrease the risk of developing cardiovascular disease. Coconut oil has gained popularity in recent years but it contains 90% saturated fat, which has higher percentage of saturated fat than butter. To date, only limited studies have determined the acute effects of meals containing coconut oil on blood lipids, but findings are inconsistent. Therefore, further studies are needed to address this knowledge gap and compare the postprandial effects of test meals rich in coconut oil with other sources of saturated fatty acids such as butter and unsaturated fatty acids (vegetable oils). A cross-over, double-blind, randomised acute postprandial study will be conducted in 15 healthy men. Participants will be assigned to consume the test meals rich in saturated or unsaturated fatty acids in random order on 3 separate occasions, with 3-4 weeks between each study visit. Participants will be provided with breakfast (toast with jam and milkshake, 50g fat) and lunch (toast with jam and milkshake, 30g fat). The anthropometric, blood pressure, arterial stiffness, and breath samples will be taken for each study visit. Blood samples will be collected for the measurement of fasting lipids, glucose, insulin, inflammatory markers, whole blood culture as well as blood clotting. Breath samples are collected for the measurement of gastric emptying as well as assessment of satiety using questionnaires (100 mm visual analogue scale) completed throughout the day. The findings from this study will contribute to the evidence base on how consuming meals rich in coconut oil influence the level of blood lipids as well as other biomarkers for cardiovascular disease.
Black adults are 30% more likely to die from cardiovascular disease (CVD) compared to White adults, and more than half of this racial disparity in cardiovascular mortality may be attributed to the substantially greater prevalence of high blood pressure and vascular dysfunction in Black adults. Nitric oxide (NO) is a potent signaling molecule and key regular of vascular function that is suspected to be reduced in black individuals, but can be enriched by dietary nitrate (e.g., arugula, spinach, beets). The purpose of this study is to test the hypothesis that increasing NO bioavailability via nitrate-rich beetroot juice (BRJ) will lower blood pressure and improve vascular health in Black adults.
The aim of this study is to examine the reproducibility of postprandial coronary heart disease (CHD) risk marker and sleep responses to acute exercise bouts and to quantify the magnitude of individual variability in responses using a replicated crossover design. Healthy, recreationally active men will complete two identical rest control and two identical exercise (60 min at 60% maximum oxygen uptake) conditions in randomised sequences. Fasting and postprandial venous blood samples, arterial blood pressure and arterial stiffness measurements will be taken at pre-determined intervals, and sleep duration and quality will be assessed. Reproducibility and individual variability will be examined using bivariate correlations and linear mixed modelling.
Evaluation of the effect of adherence to Mediterranean Diet on some surrogate vascular markers and on gene expression of some cardiometabolic genes
This project will assess the effects of consuming different proportions of red meat (RM) and plant-based, protein-rich foods (nuts, seeds, and soy products - NSS) incorporated into a U.S. Healthy Eating Pattern (HEP) on cardiovascular disease risk factors in adults at high risk of developing a heart-related disease.
Trimethylamine-N-oxide (TMAO), a metabolite produced by gut microbial metabolism of dietary choline, has recently been causally linked to atherosclerosis in animal models and has been shown to be predictive of cardiovascular disease (CVD) risk in some but not all cohort studies. The relevance of observations in animals to humans is unclear and little information is available on the mechanisms linking TMAO to increased CVD risk. Vascular dysfunction plays a critical role in the initiation and progression of atherothrombotic disease. Whether TMAO impairs vascular function in humans is not known. The purpose of this study is to determine if short term supplementation of dietary choline, which increases TMAO, affects CVD risk factors, such as glucose homeostasis and vascular function.
This clinical study aims to assess the efficacy of TOTUM-070, a mix of 5 plant extracts, on lipid metabolism in moderate hypercholesterolemic subjects. The hypothesis is that TOTUM-070, daily consumed, is superior to placebo for decrease of fasting blood LDL-cholesterol concentration (determined by ultracentrifugation method) after 24 weeks of consumption.
High blood pressure (BP) is one of the principal cardiovascular risk factors. While BP levels and hypertension prevalence are well characterized in many populations, information on BP and on cardiovascular risk profile in high altitude inhabitants is limited and frequently contradictory, especially in the large highland populations of South America. The information on the effects of permanent high altitude exposure on cardiovascular variables including BP may be relevant in the light of the known BP-increasing effect of acute exposure to high altitude hypoxia. This information may have practical implications for millions of people living at elevated altitudes in Asia, South America and Africa. The inconclusive epidemiological evidence on BP and cardiovascular risk in high altitude dwellers may be the result of several factors, among them: 1) confounding by genetic and socio-economic factors; 2) imperfect methods of BP evaluation, in particular lack of data on ambulatory and home BP (both methods considered superior to conventional clinic BP in the assessment of exposure to high BP). On this background, the general aim of the study is to compare blood pressure levels and cardiovascular risk profile among population-based samples of subjects residing in Peruvian communities living at different altitudes.
In 2017, cardiovascular diseases (CVDs) were the leading cause of death worldwide. Most cardiovascular diseases can be prevented by changing risk behaviors. CVDs are distributed within a population along a socio-economic gradient. This is true within a country, but also between countries with different income levels. People living in a high-income country have better CVD health status than those living in a low-income country. Several studies have shown that community-based primary prevention of cardiovascular disease can be effective. Other studies have shown that champions positively influence the implementation of health promotion strategies at the community level. These champions are people in the community who contribute to the implementation of new health programs by involving their local networks. The SPICES project (Scaling-up Packages of Intervention for Cardiovascular disease prevention in selected sites in Europe and Sub-Saharan Africa) is an international study that aims to implement and evaluate a community-based cardiovascular disease prevention and control program. It involves 5 low, middle and high income countries, including populations in urban, semi-rural and rural areas. The study focused on four sets of interventions: health promotion, cardiovascular risk profiling, management and self-management and follow-up. In France, the territory of Central West Brittany (CWB) was chosen to participate in the SPICES project because of the vulnerability of its population to cardiovascular disease. It is in this context that a type 1 hybrid study is being set up in the CWB territory as part of the SPICES project. For the quantitative part of the protocol (NCT03886064), a randomized controlled trial took place simultaneously to evaluate the effectiveness of a behavior change program led by community champions. Resident volunteers were selected based on their non-laboratory Interheart score. Those with a moderate risk were included in the trial. They were then distributed at random to an intervention group and a control group. The control group received minimal counseling. Those in the intervention group were brought together in support groups, with follow-up by champions. In a type 1 hybrid trial, qualitative data on implementation are gathered. The qualitative study will seek to better understand the profile of these champions. A qualitative approach using semi-structured interviews and focus groups was used. The objective is to explore the barriers and facilitators to their participation in support groups for the primary prevention of modifiable cardiovascular risk factors.
This is a prospective, multicenter, cross-sectional study to evaluate prevalence of vascular risk factors in children with Down Syndrome and to determine the association between vascular disease risk factors and objective markers of early atherosclerosis.
