Filter by:Cardiovascular is a major cause of mortality in Iran, accounting for 45.7% of deaths. In Golestan (North Eastern Iran) preliminary findings from follow-up of the Golestan Cohort are consistent with national figures: with 45% (at least 22 of 48 deaths) of all deaths attributed to cardiovascular events. Cardiovascular diseases will become an increasing problem as the Iranian population ages. In 2003 Law and Wald proposed prevention of cardiovascular disease using fixed-dose combination therapy combining antihypertensive, lipid lowering and antiplatelet drugs in a single preparation. They proposed that this treatment should be offered to all persons at high risk of cardiovascular disease whether or not they have elevated blood pressure or elevated serum lipid concentrations. This pilot study aims to investigate the safety and efficacy of fixed-dose combination therapy with two antihypertensive drugs, aspirin and atorvastatin in a population who would not currently be considered eligible for antihypertensive treatment or for lipid lowering treatment. Methods: This is a double-blind randomized controlled trial. The intervention group will be assigned to take a tablet consisting of a single daily tablet comprising Aspirin 81mg, Hydrochlorothiazide 12.5mg, Enalapril 2.5mg and Atorvastatin 20mg. The control group will be assigned to an identical placebo. The population studied includes men aged 50 to 80 (inclusive) and women aged 55 to 80 (inclusive) who are currently not eligible for or taking antihypertensive or lipid lowering therapy. Persons who are found at baseline to have blood pressure >160/100 mm Hg, total cholesterol >240mg/dL, existing cardiovascular disease or to be taking antihypertensive ore lipid lowering therapy are excluded. It is intended to randomize and follow up 500 subjects for 12 months. The primary outcome for the purpose of sample size calculation is change in systolic blood pressure. Additional outcomes include change in diastolic blood pressure, change in LDL cholesterol and occurrence of adverse events.
To confirm that patients who receive the Star-Close vascular closure system (VCS) can safely ambulate within 30 minutes of catheterization.
The aim of the proposed study is to implement and evaluate Outreach Facilitation as a means to increase the uptake of evidence-based practice for secondary prevention and management of patients with established CVD and cardiovascular risk factors, in primary care practices throughout the Champlain LHIN. This initiative centers on the use of an Outreach Facilitation Model, in which skilled health professionals known as facilitators (Practice Change Consultants) serve as an expert resource to primary care practices in three areas: a) practice performance assessment, feedback, and consensus building towards goal setting and implementation; b) clinical, technical, organizational resources and practical advice; and c) encouragement to face and move through the challenges associated with implementing system change.
The purpose of this study is to determine whether short-term exposure to a compound found in some fruits and vegetables (anthocyanin), is effective in improving skin health and reducing the levels of various markers of cardiovascular disease risk. A range of skin health parameters are being studied and volunteers are also providing skin biopsy, urine and blood samples. 62 postmenopausal women have been recruited for this study.
The TAXUS ARRIVE 2 study is a multi-center safety and surveillance study designed to to compile safety surveillance and clinical outcomes data for the TAXUS™ Express2™ Paclitaxel-Eluting Coronary Stent System in routine clinical practice and to identify low frequency TAXUS related clinical events.
A randomised three period cross over trial will be carried out in adults (19-64 years) to assess the acute and chronic effects of a large dose of apple procyanidin (PA) compared with a low dose of apple PA (negative control) and aspirin (positive control), on platelet function and other risk factors of cardiovascular disease. Platelet function will be assessed prior to a run in diet and at the start and end of each intervention. Volunteers will be assigned at random to consume 230grams of low PA apple puree or high PA apple puree or aspirin (75mg) each day for 2 weeks followed by a minimum 14 day wash out. Hypothesis: Consuming apple PA reduces platelet function consistent with reduced risk of cardiovascular disease.
The purpose of this pilot study is to provide data on the feasibility of conducting a large clinical trial on the polypill (combination of aspirin, angiotensin converting enzyme inhibitor, thiazide diuretic, and statin) for primary prevention of cardiovascular disease (CVD). We hypothesized that A "polypill" comprising the aforementioned four components would significantly reduce the estimated 10-year total CVD risk score with high adherence and no significant increase in adverse effects compared to the standard practice.
Coronary heart disease (CHD) is the largest contributor to morbidity and mortality in the Western world and is associated with high-calorie diet, high body mass, and a variety of other factors. CHD can lead to myocardial infarction (MI) and other embolic events. In some areas such as France, though, a paradox of high-cholesterol diets but low CHD and MI incidence have been found. This paradox has been traced to the consumption of red wine. Further research suggests that components of the grapes used in red wine may be the source of the cardio-protective factors that have resulted in the French paradox. These components are also present in purple grape juice (PGJ). PGJ has been shown to have a variety of potential cardio-protective effects, including inhibition of platelet aggregation. Since PGJ does not contain alcohol it may provide an additional benefit by avoiding the physical and social implications of alcohol abuse. Since most of the research of PGJ has been in vitro, though, and the few studies in vivo have been in cross-over studies and over very short durations of 7 to 14 days, additional research is required to determine whether the long-term consumption of PGJ is of additional and sustained benefit, similar to long-term use of red wine in France. The proposed study is a 2 arm randomized, controlled (double-blind) study of PGJ and a calorically-matching placebo drink in 100 healthy individuals.
This study is being conducted to provide initial safety and tolerability data as well as to provide PK data on potential interactions when GW856553 and rosuvastatin are co-administered in healthy male adults
Epidemiological studies definitively show that fruit and vegetable consumption is positive for health and more specifically for cardiovascular diseases (CVD) prevention. In France, among fruits, those which are the most frequently consumed are citrus fruits essentially as juices and more specifically as orange juices. However, their health effects have been poorly studied so far. Citrus fruits contain vitamin C associated with various phytomicronutrients i.e. carotenoids (essentially -cryptoxanthin) and polyphenols. Each fruit contains specific compounds: hesperetin in orange, naringenin in grapefruit, eriodyctiol in lemon. Some scientific studies performed either in vitro or in animal models demonstrated properties of these micronutrients which could contribute to a positive health effect of citrus fruits on vascular protection. However data are still missing. The main goal of this project is to characterize the effect of orange juice consumption on vascular disease risk factors and to evaluate the specific role of their micronutrient compounds (polyphenols and carotenoids) in this protection. To reach this goal, a randomized "cross-over" clinical study will be performed on volunteers presenting a mild hypercholesterolemia. They will consume for 4 weeks an orange juice or a reconstituted drink similar to the orange juice for its composition in carbohydrates, minerals, vitamin C and folates but without phytomicronutrients. The effect of the juice consumption on the vascular function will be monitored exploring lipid abnormalities in plasma, measuring endothelial vasoreactivity (FMD) (Flow Mediated Dilatation), as well as endothelial dysfunction, thrombosis, inflammation and oxidative stress biomarkers in plasma. Comparison of urinary metabolomes after orange juice consumption or that of the reconstituted drink will lead to the identification of the metabolic pathways modulated by the orange juice micronutrients. Moreover ELISA tests for the two major flavanones from citrus fruits (hesperetin and naringenin) will be developed. They will be used to determine the plasma levels of these molecules in order to analyze the relation "ingested quantity - bioavailable quantity - physiological effect". The results obtained in this project will allow clarifying citrus fruit effects, and particularly orange juice, in vascular protection.
