Filter by:Heart Attacks are a major cause of death in this country. When patients have a heart attack, they are treated with anti-clotting drugs, one of which is a drug called Prasugrel. It is important that Prasugrel starts to work as quickly as possible following a heart attack. As many patients who have a heart attack experience excruciating pain, they are often given morphine (a strong painkiller) by the Ambulance crew. We think that morphine may affect how Prasugrel is absorbed from the stomach and may delay how quickly it starts to work. We intend to study the effect of morphine on the absorption of Prasugrel.
Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects approximately 1% of all Canadians. RA is associated with a higher rate of disease and death as well as a decreased life expectancy. Changes in death rates and life expectancy are mainly the result of an increased frequency of cardiovascular disease (CVD). The increase in CVD frequency is primarily attributable to accelerated atherosclerosis. It is believed that elevated levels of inflammation, which are characteristic of RA, play a key role in accelerated rate of CVD in RA patients. Thus, inflammation is considered a primary risk factor for CVD in RA patients. Interestingly, despite a better understanding of the relationship between RA and CVD and improved treatment for RA patients the death rate in RA population continues to increase. Thus, there is an immediate need to develop treatment strategies to reduce the risk of CVD associated with inflammation in the RA population. Exercise is commonly used to reduce the risk of CVD. Preventative exercise programs are often offered as part of cardiac rehabilitation (CR) programs. These programs help patients modify CVD risk factors, improve physical capacity and decrease CVD risk. Studies also suggest that CR programs decrease levels of inflammation. Since RA patients have an elevated risk for CVD, which is primarily attributed to increased levels of inflammation, they are prime candidates for CR programs. However, RA patients are very rarely referred to CR programs. Thus, there is a lack of information regarding the effects of CR on RA patients. Thus studies are needed to determine whether CR modifies levels of inflammation and decreases CVD risk in RA patients. Therefore, the purpose of this study is to determine the effects of a 12-week standardized cardiac rehabilitation exercise program on systemic inflammation and CVD risk in individuals with RA. Specifically, this study will characterize the effects of a community based CR exercise program on systemic markers of inflammation (proinflammatory cytokines) and global CVD risk (Framingham risk profile) as well as the therapeutic effects of CR exercise on the severity of RA. This study will help to clarify the mechanism(s) by which exercise impacts CVD risk in patients with inflammatory disease. In addition, the study will show how CR may benefit patients with inflammatory disease with respect to their ability to exercise, global risk for cardiovascular disease and quality of life.
This study is set up to determine pharmacokinetics of phenolic acids after a single oral dose to healthy males.
The primary aim of this placebo-controlled study is to determine whether flavonoids beneficially affect markers of cardiovascular disease risk in healthy subjects at elevated cardiovascular risk. The underlying mechanisms of action of flavonoids will be assessed on blood biomarkers and we will assess the effects of the food matrix, and aspects of isoflavone metabolism.
Objective: The purpose of this study is to determine the etiology of the weight increase in Depot-medroxyprogesterone Acetate (DMPA) users. Method: Prospective study with 100 women, aged 18-40 years old and BMI < 30kg/m², paired with users of a non hormonal method follow for two years. Will be included only women who never used DMPA. There will be evaluated habit, blood pressure, anthropometric measure, distribution of corporal fat, lipids profile and glycemia parameters every six months. Thirty women and their control group will performed a euglycemic-hyperinsulinemic clamp to evaluate the resistance of insulin, adiponectin,neuropeptide Y, apolipoprotein A/B and arterial evaluation with ultrasound, intimal and media measure. Anova analysis for repeated samples. The metabolic alterations should elucidate the etiology, and the beginning of the sub clinical cardiovascular disease should be shown/discarded with the arterial evaluation.
The purpose of this study is to assess the benefits of endovascular repair with Endurant Stent Graft System by documenting overall mortality, complications, the rate of conversion to open surgical repair, and the development and rupture of the aneurysm on a long term, i.e. at 5 years, in a cohort of patients representative of the population treated under real-life conditions of use in France.
Background: - The endothelium is the inner lining of blood vessels. The cells in this lining help regulate blood flow and immune system function. Problems with endothelial cells can contribute to heart disease, high blood pressure, and diabetes. Certain genes or parts of genes may be related to problems with endothelial function. Researchers want to study healthy adults who have genes that may affect their endothelial function. More information on these genes may provide more information on genetic risk for certain diseases. Objectives: - To study healthy adults who have genetic markers related to endothelial cell problems. Eligibility: - Healthy volunteers between 18 and 65 years of age. - Current participants of the Environmental Polymorphisms Registry and have certain genes related to endothelial cell problems. Design: - Participants will have a single study visit to collect information and samples. - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - Participants will have an ultrasound of the artery in the arm and will be given a short-acting medication called nitroglycerin to study blood flow and blood pressure.
The purpose of the study is to evaluate the effect of dietary supplementation of bromelain (a proteolytic enzyme from the pineapple plant) on the reduction of plasma fibrinogen level among type 2 diabetic subjects who have a high risk of cardiovascular disease. The null hypothesis [Ho] is: there is no significant improvement in plasma fibrinogen, serum lipid profile, blood pressure, BMI, waist circumference and C-reactive protein for subjects with type 2 diabetes who are at risk of CVD following the intervention of bromelain supplementation compared to placebo group. The alternative hypothesis [H1] is: there is a significant improvement in plasma fibrinogen, serum lipid profile, blood pressure, BMI, waist circumference and C-reactive protein for subjects with type 2 diabetes who are at risk of CVD following the intervention of bromelain supplementation compared to placebo group.
Cardiovascular disease (CVD) is the greatest cause of morbidity and mortality in the UK. Abnormalities in the concentration and/or composition of lipoproteins (the lipid carrying particles), in particular low density lipoproteins (LDL) in circulation, is one of the most important physiological defects contributing to the development of CVD. The LDL cholesterol (LDLC) response to fatty acid change is in part mediated by the APOE genotype, with E4 individuals (25% of the UK population) being most responsive to changes in dietary fats, showing greater reductions when low levels of saturated fats or fish oils are consumed and greater increases when high levels of these fats are consumed. Therefore the aims of the present study is to understand the mechanism that regulates the higher LDLC response associated with saturated fatty acids and fish oil consumption in healthy men prospectively recruited based on their APOE genotype.
The purpose of this study is to see if intestinal bacteria plays a role in choline metabolism (a form of choline monitored in this study is called phosphatidylcholine, also known as lecithin). This study will help to determine if choline metabolism is affected by short-term antibiotic therapy, and/or can be altered by probiotic therapy (e.g. in the form of eating yogurt).
