Filter by:Lipoprotein(a) [Lp(a)] is an independent risk factor for cardiovascular disease. Non-medical treatment measures (e.g. dietary therapy or weight loss) can hardly influence Lp(a) plasma concentrations. Drug therapy has only limited influence, e.g. treatment with niacin. Statins are usually without effect. Lipid apheresis is the only treatment known to lower elevated Lp(a) levels in a relevant way. In patients with pronounced elevation of Lp(a) and normal LDL cholesterol levels, who suffer from progressive cardiovascular disease, the treatment with lipid apheresis seems to be a last-resort treatment option. The current trial will evaluate the effectiveness of lipid apheresis on cardioavascular endpoints.
The purpose of this study is to evaluate the effect of fasting on physical changes associated with cardiovascular disease.
This multicenter, double-blind, randomized, placebo-controlled study will evaluate the effect of dalcetrapib 600 mg on artherosclerotic disease progression, lipid profile and biomarker profile and long-term safety profile of dalcetrapib in patients with coronary artery disease. Atherosclerotic disease progression will be measured 1. Coronary Intravascular Ultrasound (IVUS), Quantitative Coronary Angiography 2. Carotid B-Mode Ultrasound Intima Medial Thickness (IMT) and total plaque volume in subjects undergoing coronary angiography who have coronary artery disease (CAD). Patients will be randomized to receive dalcetrapib 600 mg orally once a day or placebo. The anticipated time on study treatment will be 24 months. The target sample size is 800-1000 patients.
People with established cardiovascular disease need secondary prevention that addresses multiple risk factors. Complexity & cost confer particularly difficult barriers to uptake of treatment; recovery from a stroke or heart attack typically necessitates multiple drugs for cholesterol, blood pressure and platelet function. A low-cost, fixed-dose, once-daily combination polypill, the Red Heart Pill, has been formulated by Dr Reddy's Laboratories. UMPIRE will evaluate whether provision of this polypill compared with usual medications improves adherence and clinical outcomes among high-risk patients in Europe and India. The results will be used to develop recommendations for equitable access.
Cardiovascular disease (CVD) has been associated with HIV infection. However, it is uncertain whether increased CVD rates are associated with HIV-related factors (e.g., HIV-infection or highly active antiretroviral therapy (HAART) may worsen dyslipidemia) or reflect differences in the prevalence of underlying risk factors for CVD. Furthermore, the association between initiation and duration of HAART exposure and CVD risk, including which specific drugs within the HAART classes may contribute to the increased risk, is unknown. The primary objectives of the study are therefore: 1. To estimate the absolute and relative incidence rate (IR) of CVD claims-based diagnoses among a cohort of adult patients from a large managed care population with a claims diagnosis of HIV, AIDS, or AIDS-related complex (ARC) during periods of exposure to: - Any HAART compared to no HAART exposure - HAART class [i.e., NRTIs, NNRTIs, PIs, and Other (i.e., fusion inhibitors)] compared to no HAART class exposure - Specific NRTI medications compared to no specific NRTI exposure
The study will involve cardiac rehabilitation clients and will measure their weight, height, waist circumference and blood pressure comparisons between first and final visit (after 8 weeks). A control group will receive usual care and an experimental group will receive usual care plus a portion control plate for their meals. Patients currently have their waist circumference, weight, height and blood pressure measured at their first visit (week 0) and at their final visit (week 8). This study would compare these three parameters at these same times (week 0 and week 8) between the control and experimental groups. The control group would receive the usual care while the experimental group would receive usual care plus be given a portion control plate at week 0. The hypothesis of this study is that subjects from the experimental group will have an average reduction in: (a) waist circumference by > 5%, (b) weight or BMI by > 5%, and (c) systolic and diastolic blood pressure by >10%. The subjects in the control group are hypothesized to show an average less than these targets for the experimental group.
The purpose of this study is to prospectively explore the impact from the different cardiovascular risk factors on early cardiovascular organ damage in 761 middle aged patients with type 2 diabetes.
In the United States, cardiovascular disease causes over one-third of all deaths and vitamin D deficiency is an epidemic. An increasing body of data suggests that low vitamin D status adversely impacts the cardiovascular system. It is our fundamental hypothesis that vitamin D deficiency is a risk factor for cardiovascular disease by causing endothelial dysfunction. Moreover, we hypothesize that vitamin D supplementation will restore endothelial function, thereby reducing cardiovascular disease risk. This pilot research will be conducted in 64 post-menopausal women participating in an existing study of vitamin D supplementation (32 will receive vitamin D3 2,500 IU daily, the others matching placebo) and will explore the effects of vitamin D on endothelial function and arterial reactivity. Post-menopausal women aged 55-65 years are chosen due to their highest risk for development of a subsequent new cardiovascular disease diagnosis. All study participants will have fasting laboratory and noninvasive vascular ultrasound studies performed at baseline and four months later. The primary outcome measure of this pilot study is change in markers of endothelial function and arterial stiffness with vitamin D3 therapy. If our hypotheses are correct, our long-term goals include investigation of the effect of vitamin D repletion on subclinical atherosclerosis and subsequent cardiovascular events.
Menopause is characterized by a decrease of estrogen and progesterone levels and is associated with various changes in body composition, including an accumulation of total fat mass, a relocation of adiposity to the abdomen, deterioration of plasma lipid profile, increased risk of type 2 diabetes, and increased oxidative stress. Taken together, these changes increase the risk of developing cardiovascular disease (CVD). Physical activity and hormone-replacement therapy (HRT) have been shown to act in synergy to improve total fat mass in postmenopausal (PM) women. Because the progesterone component of HRT has been associated with an increased CVD risk in older women with a family history of CVD, the use of HRT has become controversial. As a result, a large decrease of the use of HRT in the community has been observed and postmenopausal women (PM) have developed interest in alternative therapies. Among the possibilities, phytoestrogens have shown beneficial effects on menopausal symptoms and plasma lipids. Phytoestrogens are structurally and functionally similar to estradiol (the major estrogen in humans) but found only in plants such as soybean isoflavones. They do not exert any effect on breast cancer or/and endometrial tissue. AIMS To examine the effects of phytoestrogens, exercise and the combination of both on lean body mass, total fat mass, visceral fat, blood lipid profile, oxidative stress markers, antioxidant system, glucose metabolism, and sex-hormone levels in obese PM women. HYPOTHESES Women undergoing a combination of phytoestrogen treatment and an exercise program will display a greater increase in lean body mass, decrease in total and visceral fat mass, improvements in blood lipid profile, decrease in oxidative stress markers, increase in antioxidant system, improvement in glucose metabolism, and increase in sex-hormone levels than those submitted to any or one of the treatments. A total of 120 women will be recruited. There will be 4 groups (30 women/group) undergoing exercise or not and supplemented with phytoestrogens or a placebo. The intervention is planned to last 12 mo. Key variables will be measured at baseline, and after 6 and 12 mo of intervention. Three weekly 1h-sessions of exercise will be held on 3 non-consecutive days. The phytoestrogen supplements will consist of 70 mg/d of soy isoflavones taken as 4 caps/day.
The purpose of this study is to better understand the anti-inflammatory benefits of two prescription medicines that are currently used to help people with cholesterol problems. Fish oil, from eating certain kinds of fish and from supplement pills, has been used to help control cholesterol and reduce inflammation (the body's response to injury or sickness). Lovaza® is the brand name for prescription strength fish oil pills. In this study, we will be looking at how Lovaza® works to help reduce inflammation in healthy volunteers. Tricor® is the brand name for prescription fenofibrate pills. Fenofibrate is a prescription medicine that many doctors give to people with high triglyceride (fat in the blood) levels. In this study, we will be looking at how Tricor® works to help reduce inflammation in healthy volunteers. Endotoxin or lipopolysaccharide (LPS) is a small part of bacteria (that is no longer living) that can cause many of the effects similar to bacterial infections in humans. However, it can be administered in very small amounts to produce a mild immune response much the same as a 'flu' like illness. Within 1 ½ -3 hours after giving LPS by vein, a response consisting of fever, chills, headache, nausea and vomiting and generalized aches and pains will occur which lasts up to 6-8 hours. In addition to the flu like symptoms, the response causes temporary changes in cholesterol, triglycerides and blood sugar. Different people respond differently to LPS. We are using LPS in this study to bring on a temporary inflammatory response in the body and to compare the responses of people who receive Lovaza® or Tricor® to the responses of people who receive a placebo (pill that does not contain medicine).
