Filter by:Resveratrol can exhibit benefits against cardiovascular diseases (CVDs) although the cardioprotective role of resveratrol as part of the human diet is not yet clear. The aim of this trial is to evaluate the safety and efficacy of a resveratrol-enriched grape extract (Stilvid) in 150 patients from both primary and secondary cardiovascular prevention. All the patients are gold-standard medicated (statins and others). A number of cardiovascular risk and safety markers will be evaluated after consuming 1 cap/day for 6 months and 2 caps/day for 6 additional months (total 12 months).
Three out of four Veterans receive a portion of their care from non-VA providers. On April 9, 2009, President Barack Obama directed the Department of Veterans Affairs and the Department of Defense to create the Virtual Lifetime Electronic Record (VLER). On August 2010, Secretary of Veterans Affairs Eric K. Shinseki visited Indianapolis, and after visiting with leaders from the VA Health Services Research & Development (HSR&D) Center of Excellence and the Regenstrief Institute, he made the following public comments regarding the latest partnership between the two institutions: "This new technology allows safer, more secure, and private access to electronic health information which, in turn, enhances our ability to continue providing Veterans with the quality care that they have earned." This new technology refers to the VLER HEALTH program that the Indianapolis VA is now implementing in partnership with the Regenstrief Institute and Indiana Health Information Exchange (IHIE). This VA-IHIE demonstration project is intended to create the capacity for VA institutions to exchange health information with community partners. Investigators from the VA HSR&D Center on Implementing Evidence-Based Practice are active collaborators in building and implementing this program. The VA-IHIE program provides the bi-directional exchange of health information between VA and non-VA providers. Based on our pilot study of linked VA-IHIE data, investigators are conducting an evaluation of the impact of the VA-IHIE demonstration project upon health care quality and cost of Veterans by taking advantage of the initiation of the implementation as a natural experiment.
The purpose of this study is to find out if tadalafil can help overweight and obese people metabolize blood sugar more efficiently. The investigators also want to find out if 20 mg/day of tadalafil for 3 months is safe to take without causing too many side effects. The investigators are plan to enroll 100 subjects at Massachusetts General Hospital (MGH).
Inflammation and endothelial dysfunction are being increasingly recognized as key etiological factors in the development of atherosclerosis and subsequent cardiovascular disease (CVD). These pro-atherogenic states are strongly correlated and often found co-segregating among individuals with obesity and the metabolic syndrome. There is increasing evidence to support the use in clinical practice of these novel markers of atherosclerosis and CVD risk. Recent data from the JUPITER study (Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin) has provided undisputable evidence that treating patients with elevated plasma CRP concentrations, a marker of systemic subclinical inflammation, leads to marked reduction in the risk of CHD even in patients with highly desirable LDL-C levels. There is also accumulating evidence associating endothelial dysfunction, which is defined as incapacity of the arteries to vasodilate when required, to an increased risk of CVD. While there are more and more studies on how diet affects inflammation and endothelial function, the impact of dairy consumption per se on these novel risk factors for CVD has not been well characterized. The purpose of this study was to investigate the impact of dairy consumption on markers of inflammation and other risk factors in men and women with low grade systemic inflammation.
The goal of the study is to determine whether grape consumption can reduce the risk of cardiovascular disease by reducing the presence of inflammatory molecules and positively altering cholesterol levels, lipid profiles, and immune cell responses.
The CONFIRM study was developed to examine the prognostic value of cardiac computed tomographic angiography (CCTA) findings for prediction of future adverse cardiac events related to coronary artery disease (CAD) in a large, international patient population. The purpose of this multicenter registry is to correlate coronary and non-coronary cardiac findings by CCTA with demographic and clinical data for refinement of risk stratification of individuals with suspected or known CAD.
Balloon angioplasty (Percutaneous Coronary Intervention (PCI)) is commonly used to treat patients with obstructive coronary artery disease (CAD). Although PCI is highly effective for the management of CAD, it can potentiate an existing prothrombotic state around lesion areas. A certain level of anticoagulation is required to perform planned PCI safely and to minimize the periprocedural risk of thrombosis and its attendant complications, including myocardial ischemia and infarction (heart attack). Many different anti-thrombotic regimens have been investigated and are currently in use. The aim of this study is to explore whether Rivaroxaban, as compared to unfractionated heparin, on the background of standard dual antiplatelet therapy, can effectively suppress thrombosis and related adverse ischemic events, upon balloon inflation and stent expansion, during elective PCI, without increasing bleeding. The treatment assignment will be done in a semi-blinded design, eg, no blinding for randomization either to Rivaroxaban (one of the three arms) or the control (UFH) group. However, all will be blinded for the treatment dose of rivaroxaban (either 10mg or 20 mg).The 10 mg rivaroxaban plus 50 IU UFH arm will not be blinded.
The objective of this study is to determine the effect of reducing the rate of glucose absorption on oxidative stress after eating and to compare it with the effects of vitamin C. The hypothesis is that reducing the rate of glucose absorption will reduce oxidative stress to a similar extent as 1g vitamin C.
Cardiovascular disease (CVD) is the leading cause of death for women in the United States. CVD disproportionately affects underserved populations, specifically low-income, minority, and rural women who have higher obesity rates and experience other health disparities. There is a need for replicable, evidence-based programs that target women, particularly midlife and older women who represent an increasing proportion of the U.S. population, to reduce their CVD risk . StrongWomen - Healthy Hearts is a 12-week, community-based program that has demonstrated effectiveness at improving CVD risk factors, including body weight, diet quality, and physical activity in a controlled, randomized trial conducted with midlife and older overweight and obese subjects in Arkansas and Kansas. The central objective is to rigorously evaluate dissemination of the StrongWomen - Healthy Hearts Program using the RE-AIM framework to achieve maximal public health impact. Expanded dissemination will occur through the Cooperative State Research, Education and Extension Service (CSREES) This partnership will leverage a long and successful collaboration between Tufts University and CSREES that provides strength training programs to older women in 41 states.
Rationale: In patients with a myocardial infarction, occlusion of a coronary artery induces myocardial ischemia and cell death. If untreated, the area of myocardium exposed to this interruption in blood supply, will largely become necrotic. The only way to limit final infarct size, is timely reperfusion of the occluded artery. Paradoxically, however, reperfusion itself can also damage myocardial tissue and contribute to the final infarct size ("reperfusion injury"). Also during coronary artery bypass grafting (CABG), the myocardium is exposed to ischemia and reperfusion, which will induce cell death. Indeed, postoperatively, the plasma concentration of troponin I, a marker of cardiac necrosis, is increased, and associated with adverse outcome. The anti-hyperglycaemic drug metformin has been shown in preclinical studies to be able to reduce ischemia-reperfusion injury and to limit myocardial infarct size. Moreover, metformin therapy improves cardiovascular prognosis in patients with diabetes mellitus. Paradoxically, in patients with diabetes, current practice is to temporarily stop metformin before major surgery for the presumed risk of lactic acidosis, which is a rare complication of metformin. However, here is no evidence that this practice benefits the patient. The investigators hypothesize that pretreatment with metformin can reduce myocardial injury in patients undergoing elective CABG surgery
