Filter by:Rheumatoid arthritis (RA) is a symmetric, peripheral polyarthritis of uncertain etiology that can lead to joint deformity and destruction. However, the effects of RA are not confined simply to joint involvement. Virtually every organ system can be affected by RA if left untreated. Of particular note is RA’s affect on the cardiovascular system. RA patients have a reduced lifespan compared to the general population primarily due to an increased cardiovascular disease burden (1). Recently, RA has been linked to the development of preclinical atherosclerosis in the carotid arteries as measured by ultrasonography (2). Women with RA have also been shown to have an increased incidence of nonfatal myocardial infarctions (3). Despite these studies showing the effects of RA on the cardiovascular disease burden of those who are afflicted, no study to date has compared the number of cardiovascular events in a large RA patient population to a risk factor and age matched control group. Consequently it is the goal of this study to determine whether the cardiovascular event ratio in an RA patient cohort exceeds an age and risk factor matched cohort of non-RA patients. This study will also attempt to ascertain whether specific cardiovascular risk factors contribute to the cardiovascular morbidity and mortality associated with RA and if any standard cardiovascular medicines disproportionately contribute to patient outcome. Hypothesis: Given the increased cardiovascular disease burden associated with RA patients they are likely to suffer from a statistically significant increased risk of cardiovascular events when compared to an age and risk factor matched cohort.
The purpose of the registry is to collect and analyze clinical and laboratory data and tissue samples from patients who are diagnosed with any type of heart disease and to collect the same information and samples from healthy controls in participating Intermountain Healthcare facilities.
Metabolic Syndrome (hypertension, diabetes mellitus, obesity, cerebrovascular-cardiovascular disease) In Community Survey was performed in central Bangkok. Prospective Cohort and intensive educated intervention (health promotion program in specific high risk groups) were performed. The aim of the study is to identify high risk patients who can develop serious complications from metabolic syndrome. An analysis of health outcomes in multiple dimensions will be performed.
Studies have established that high blood pressure (BP) is the most common risk factor for cardiovascular disease (CVD). Despite a heavy burden of hypertension (33% of all persons aged 45 years and over), there are no reliable data on comparative strategies to manage hypertension in Pakistan. Our Wellcome Trust funded pilot study in Karachi, Pakistan on 320 adults aged 40 years and over showed that the prevalence of hypertension (95% CI) was 40.3% (34.9-45.7%), and CVD was 32.5% (27.6-37.8%). We will now conduct a study with two components: 1) cross sectional study to determine the prevalence of CVD, and its determinants in Karachi, Pakistan; and 2) prospective, 2x2 factorial design, cluster allocation intervention study to evaluate the impact of a i) Population approach of household health education (HHE) by community health workers (CHW) on BP levels of population aged 5 years or over in low-middle income communities of Karachi; and ii) High-Risk approach of special BP management administered by intensively trained local general practitioners on BP levels of hypertensive subjects aged > = 40 years from the above population. The cost effective BP control strategy would serve as a model for a much-needed national level hypertension control programme in Pakistan, and possibly other developing countries in South Asia. We hypothesize that 1) HHE delivered by trained CHW is superior to no HHE in lowering BP levels of the population; and 2) management of hypertension by specially trained GPs is better than usual care provided in the communities of Karachi in lowering blood pressure of hypertensive subjects.
The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be significantly associated to muscle mass gain.
Study Objective: 1. To evaluate whether combined therapy with folic acid 2.5 mg/day, vitamin B6 50 mg/day and vitamin B12 1000 micrograms/day vs placebo reduces the rate of atherosclerosis progression, as evaluated by quantitative B-mode carotid ultrasound (US).
The primary focus of this study is to collect information through diagnostic testing, blood sample analysis and patient data collection on patients starting hemodialysis to determine risk and preventative factors of bleeding and clotting events.
There is evidence linking cardiopulmonary bypass to negative side effects when used for coronary artery bypass grafting. Coronary artery bypass grafting can be performed without the use of cardiopulmonary bypass. The purpose of this study is to determine the positive and negative effects of coronary artery bypass grafting with or without the use of cardiopulmonary bypass. The patients will be followed at least one year after surgery.
The purpose of the HOPE-2 study is to determine whether long term supplementation with folic acid, vitamins B6 and B12 aimed at homocyst(e)ine reduction reduces the rates of major fatal and nonfatal cardiovascular events in patients with established cardiovascular disease and/or diabetes mellitus.
To characterize the natural history and biologic spectrum of sleep disordered breathing (SDB) and other sleep problems and disorders, and test hypotheses regarding the causes and consequences of SDB and other sleep problems and disorders.
