Filter by:The aim of the present study is to describe and evaluate the effect of a structured lifestyle intervention program, focusing on lifestyle habits, in a primary care setting in patients with high cardiovascular risk. Furthermore, we want to explore the patient´s experience of lifestyle change and counseling after participation in the intervention program and to investigate the cost-effectiveness of the program.
The goal of this study is to examine possible mechanisms of impaired vasodilaton in obese and Black/African American men and women as possible links to the elevated prevalence of cardiovascular dysfunction and disease. The main targets in this study are sources of oxidative stress.
The goal of this study is to examine possible mechanisms of heightened vasoconstriction in Black/African American men and women as possible links to the elevated prevalence of cardiovascular dysfunction and disease. The main targets in this study are sources of oxidative stress

The goal of the study is to examine the possible mechanisms of impaired cutaneous microvascular function through local heating along with administration of vasoconstrictors.
Although asthma is a disease of the airways, research is now showing that asthmatics are more likely to develop cardiovascular disease (CVD) compared to non-asthmatics. Vascular dysfunction is seen in people at high risk of CVD and has been linked to inflammation. During an asthma attack, levels of inflammation in the whole body increase, which could potentially explain why asthmatics are at increased risk of CVD. In the proposed study the investigators will examine if asthma attacks lead to increased risk of CVD by evaluating inflammatory levels and vascular function directly following asthma attacks, 2 days and 14 days after discharge. The investigators will compare these results to non-asthmatics. The results from this study will help us understand why asthmatics are at increased risk of CVD.
Whole food-based dietary interventions have the potential to promote cardiometabolic health via multiple mechanisms, including improvements in blood pressure, bad cholesterol, and other markers of metabolic health. Previous research suggests that grapes have the potential to promote optimal cardiometabolic function by reducing LDL-C, but it remains unclear whether there is a dose-response relationship. Moreover, few studies have evaluated effects on vascular health following daily grape consumption. We propose to examine the effects of 6-8 weeks of supplementation with freeze dried grape powder (69 g/d; ~three ¾ cup servings) compared to a control powder without grapes on: 1) bad cholesterol and blood pressure and 2) other measures of cardiometabolic health, including glucose and insulin. We will enroll overweight (BMI 25-36 kg/m2) but otherwise healthy adults with moderately elevated LDL-C (>115 mg/dL for women and >130 mg/dL for men) and/or blood pressure of120-159/80-99 mm Hg. This will optimize the potential for observing significant changes in these measures of health. We will recruit 20 eligible participants with the expectation that at least 15 will complete the study. The placebo-controlled, crossover study design will allow for a direct comparison of effects within the same participant. We anticipate that the bioactive components of grapes will promote cardiometabolic health via changes in LDL-C and blood pressure. Results from the proposed study would help to clarify how daily grape consumption might promote health and would provide further support for incorporating whole, unprocessed fruit in a healthy dietary pattern.
Despite exercise training decrease blood fasting glicaemy in 'average' terms, there is a wide inter-individual variability after exercise training explored mainly in adults but not in adults with prediabetes comorbidities. Thus, is yet unknown the effects and influence of the concurrent training (CT) eliciting responders (R) and non-responders (NR) cases (i.e., percentage of subjects who experienced a non-change/worsened response after training in some metabolic outcomes).
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 acute supplementation of dietary choline, which increases TMAO, impairs vascular function.
Traditional medical treatments are often based on research done exclusively in males, and recent research efforts in the physiology community have highlighted critical sex differences in disease presentation and progression. For example, the relative risk of fatal heart disease is 50% greater in obese, diabetic women as compared to their male counterparts, and women appear to respond differently to lifestyle interventions such as exercise compared with men. Chronic passive heat exposure (hot tub use) provides alternative or supplemental therapeutic potential for improving cardiovascular and metabolic health in obese women. In addition, passive heat exposure may offer specific cellular protection from stresses like a lack of blood flow (ischemia), which is the primary cause of fatal coronary heart disease. This study is investigating the possible cardiovascular and metabolic health benefits of chronic passive heat exposure, and whether regular hot tub use (3-4 days per week for 8-10 weeks) may reduce obese womens' cardiometabolic risk. The investigators are examining cardiovascular health through blood pressure, blood vessel stiffness, sympathetic ('fight or flight') activity, and responsiveness to stresses like increased or decreased blood flow. The investigators are also examining metabolic health through an oral glucose tolerance test and a subcutaneous fat biopsy. The goal of this research is to develop a therapy targeted toward the specific health needs and complications of obese women, in an effort to improve cardiovascular and metabolic health and provide therapeutic alternatives in this high-risk population.
