Filter by:We will use a retrospective data analysis to evaluate the association of vitamin D status with clinical outcome in cardiac surgical patients. The occurrence of several postoperative adverse events such as myocardial infarction, low cardiac output syndrome, stroke and in-hospital death will be assessed from cardiac surgery to discharge. In addition, we will assess the association of vitamin D status with the duration of mechanical ventilatory support and intensive care unit stay from cardiac surgery to discharge. Moreover, in-hospital stay will be assessed according to vitamin D status.
The aim with this study is to investigate the effect of statin induced changes in HDL-C on all cause mortality and CVD with adjustment for changes in other blood lipids and clinical parameters in Sweden, UK and the Netherlands.
This study is being conducted to test the hypothesis that daily consumption of a baked food product containing whole soy for 6 weeks will significantly reduce plasma Low Density Lipoprotein Cholesterol (LDL-C) in individuals with hypercholesterolemia. As such the overall goals of this study are to determine whether daily consumption of muffins made from whole soy flour for 6 weeks can lower plasma LDL-Cholesterol, and if so, establish whether the effect is dose-dependent. To do this, study collaborators will: (1) conduct a detailed chemical and physical characterization of certified defatted whole soy flour that will be incorporated into a muffin; (2) formulate and produce a palatable whole soy flour muffin along with a control muffin containing wheat flour; (3) conduct a parallel controlled trial in which soy muffins will be fed randomly to persons with elevated LDL-cholesterol in a human clinical trial. All participants will be randomized into one of three groups and asked to eat two muffins daily for 6 weeks in the following combination: high dose soy; control group or low dose soy. Before, after, and mid-way during the feeding period, blood samples will be obtained for measurements of lipids, glucose, insulin, inflammation, and soy phytochemicals. The effect of soy consumption on waist circumference, body mass index (BMI) and blood pressure will also be examined.
The aim is to study the effects of weight loss and weight loss combined with different types of physical activity on changes in physical functioning of older adults who are at-risk for cardiovascular disease.
The main aim of this study is to determine whether there is a difference in the physiological effects of theobromine when provided via a single serving compared to multiple servings adding up to the same amount of theobromine provided on a day. This study also aims to study the pharmacokinetics of theobromine after administration once per day versus administration 4 times per day. Hypothesis: the effects on heart rate are less pronounced when a high dose of theobromine is given in 4 smaller doses.
The purpose of this project is to determine whether chokeberry polyphenols mitigate cardiovascular disease risk in former smokers.
Presence of multiple traditional and nontraditional risk factors of atherosclerosis and cardiovascular disease (CVD) including inflammation in patients with chronic kidney disease (CKD) contribute to high CVD morbidity and mortality in this patient population. Additionally, the traditional approaches towards the therapy of CVD have little impact on CV mortality in these patients. Hydroxychloroquine (HCQ) used as anti-inflammatory in rheumatological disorders, has multiple beneficial properties relevant to the process of vascular disease. The effects of HCQ on atherosclerosis (AS) and vascular disease in CKD is not known yet. Thus, the study hypothesis is that HCQ treatment in individuals with CKD will provide clinically significant benefit in the management of CVD and will provide biological and functional atherosclerotic benefits.
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.
