Filter by:Patients admitted to hospital with chest pain due to reduced blood flow to heart muscle (diagnosis Acute Coronary Syndrome) can be treated with medication and an angioplasty ± stent procedure, which restores blood flow to the heart. Antiplatelet drugs (Aspirin and Clopidogrel) are blood thinning treatments and research has reported they reduce heart attacks, death and stroke. The investigators know some patients do not respond fully to Clopidogrel but currently patients are not tested for this. The investigators wish to perform a trial to identify those patients who do not respond fully to Clopidogrel and randomise them to either Prasugrel (newer drug) or a higher dose of Clopidogrel. Patients admitted to the hospitals (2 in the UK and 1 in Germany) will be asked for their consent to participate. A blood sample is tested for platelet activity. 1. Low platelet activity result means patient has responded well to Clopidogrel and will continue on the routine dose. They will be entered into an observational registry. Data will be collected of routine blood tests and investigations, medication and procedures. Their GP will be contacted at about 30 days to see if they are alive. 2. High platelet activity results means patient has not responded fully to Clopidogrel. These patients will be randomly allocated to a higher dose of Clopidogrel or new drug Prasugrel. Data will be collected of routine blood tests and investigations, medication and procedures. A hospital visit at 30±5 days is required to assess how patients are doing, medications and occurrence of any events.
The purpose of this study is to test the hypothesis that aerobic exercise leads to attenuation of the inflammatory response to lipopolysaccharide (LPS) stimulation.
The investigators seek to demonstrate that interactive physician-led education through partnership with an African American church will improve awareness and knowledge of cardiovascular disease in the African American community and will result in objective improvement in major risk factors associated with cardiovascular disease (CVD).
Water consumption is essential to maintain hydration and good health. Sodium-bicarbonated mineral waters are reported to have beneficial digestive and hypocholesterolemic properties. The aim of this study was to investigate the effects of the consumption of a sodium-bicarbonated mineral water (BW) with or without a meal, compared to a low mineral content water as a control water (CW), on postprandial serum triacylglycerols (TAG), cholecystokinin (CCK), and gallbladder volume.
The primary objective of this study is to evaluate the in-stent late lumen loss (LLL) at 9 months, defined as the difference between the post-procedure minimal lumen diameter (MLD) and the follow-up angiography MLD, of the Resolute Zotarolimus-Eluting Coronary Stent System compared to Taxus Liberte Paclitaxel-Eluting Coronary Stent System in a real-world all-comer patient population requiring stent implantation.
It is the central hypothesis of the investigators study that HIV disease is a pro-inflammatory condition, and that years of inflammation result in premature "aging' of the immune system ("immunosenescence"). Just as these changes are thought be causally associated with heart disease in the very old,the investigators postulate that these changes will be associated with early heart disease in the untreated and perhaps treated HIV disease. To address this hypothesis, the investigators will measure immunosenescence in a large cohort of patients who span the entire disease process.
The overall goal of this randomized controlled trial is to evaluate the effects of a community-based lifestyle behavior intervention (LSBI) that is designed to improve dietary habits and physical activity (PA), and reduce weight of Latino women who are predominantly Spanish-speaking immigrants. It is hypothesized that middle-aged overweight/obese Latinas participating in a LSBI conducted by lay health advisors will demonstrate improved dietary habits, increased physical activity and a decrease in BMI compared to those in a control condition, Women in the LSBI also are expected to demonstrate improvements in selected physiologic outcomes (waist circumference, blood pressure [BP], measures of cholesterol and blood sugar).
The primary objective is to assess the impact of three months of treatment with an active vitamin D analogue on a risk marker for excess overall mortality and cardiovascular morbidity/mortality in Type 1 diabetic patients with diabetic kidney disease. The hypothesis is that active vitamin D analogue treatment reduces the risk of cardiovascular morbidity and mortality in patients with type 1 diabetic kidney disease.
The primary objective of this study is, to instigate a reduction in atherosclerotic burden within the carotid arteries in the intervention group compared to the control group and to demonstrate parallel improvements in cardiovascular and overall health status relative to usual care
The purpose of this study is to establish the safety and feasibility of low dose LPS administration to a small subset of humans in preparation for a larger USDA funded study examining what is the lowest effective dose of EPA + DHA (300, 600, 900 and 1,800 mg/day delivered as fish oil supplements) that significantly attenuates the inflammatory response the investigators wish to examine the effects of an endotoxemia model for inducing inflammation. Based on previous research, low dose LPS administration affects metabolism in humans with only minimal clinical effects (such as "flu" like illness). Therefore, each of the six subjects included in this small pilot study will receive a low dose of LPS and placebo in order to learn more about the metabolic changes that occur during administration and inflammation. The investigators hypothesis that LPS administration will elicit only minimal clinical effects (such as "flu" like illness) when compared to placebo (saline--water with the same amount of salt as in your blood).
