Filter by:The underlying hypothesis is that whole body cholesterol - including cholesterol present in tissues that cannot be measured by standard blood tests - is related to heart disease risk. Endogenous cholesterol will be labeled with an intravenous infusion of one type of cholesterol tracer and dietary cholesterol will be labeled with another. These tracers will be used to measure how fast cholesterol is synthesized and excreted using mass spectrometry to distinguish the tracers. Data will be related to circulating biomarkers (blood tests) and to the thickness of the lining of the carotid artery. The effect of the drug ezetimibe on these processes will also be determined. Successful completion of this study will give us more knowledge about cholesterol metabolism that may be useful in designing new drugs and treatments for patients with heart disease, especially those that are already receiving maximum amounts of current medications.
The objective of the CELT ACD® Vascular Closure Device study is to evaluate the safety and effectiveness of the CELT ACD® device to achieve hemostasis of the common femoral artery access site in patients on anticoagulation who are undergoing a percutaneous coronary intervention (PCI) procedure using either a 6F or 7F procedural sheath.
The UK population is ageing and the likelihood of having a long term health condition increases with age. Three out of every five people over 60 in the UK have a long term condition. Ageing and having a long term condition increases the chance of having difficulty being independent and carrying out day to day activities. In recent years the NHS has made a greater effort to prevent these difficulties in patients with long term conditions. One approach to help patients with long term conditions is case management, where by (usually) a community matron visits patients at home, looking for early warning signs of any worsening of their condition and arranging care and treatment. But the current way this is done varies across the country and hospital admissions are still rising. In order to give the right care at the right time, effective monitoring is needed to help the community matron detect and act on changes in the patient's condition. Loss of muscle strength in old age is linked to a poor health, but it is not known whether simple measures of muscle strength could be used to detect and predict declines in health in the short to medium term to help maintain independence and prevent an accident or hospital admission. The aim of this study is to look at whether monitoring muscle strength in case managed patients is practical, acceptable and useful in detecting when a patient's condition worsens. Each patient will be visited by the researcher in their home twice in the first week, then once every two weeks, for another 5 weeks, to carry out three simple measures of grip and respiratory strength, and complete questionnaires about their health and ability to carry out day to day activities. Each visit will last about 20 to 30 minutes. A small group of clinicians will be asked about their views of the strength measures. Database analysis will allow descriptive data on the patient group to be gathered and analysed.
This project will design, deliver, and evaluate a peer support intervention that will help veterans become familiar with and register for Veterans Health Administration (VHA) My HealtheVet (MHV). It will lay the groundwork for 2 types of future projects. First, the investigators will develop materials that can be used in other settings to increase registration, authentication, and meaningful use of MHV. Second, it will allow us to develop and study interventions that use informed, peer-supported Internet use to improve health behaviors and outcomes among veterans.
The use of platelet aggregation inhibitors, including aspirin and clopidogrel, has become a standard management strategy for patients with acute coronary syndrome. On this background, an increasing percentage of patients presenting for surgical coronary revascularization is the subject to irreversible platelet inhibition. Tranexamic acid is a widely used antifibrinolytic agent, and is a promising substitute for aprotinin when the latter has been suspended in 2007.The release of plasmin during CPB activates fibrinolysis and may contribute to platelet dysfunction. Pharmacological inhibition of the fibrinolytic system may therefore ameliorate platelet dysfunction and fibrinolysis after CPB and decrease postoperative bleeding. Tranexamic acid prevents plasmin formation and inhibits fibrinolysis. Many studies and meta-analyses have shown a reduction in postoperative bleeding and transfusion requirements of this antifibrinolytic drug in cardium revascularization surgery. Unfortunately the preoperative antiplatelet therapy was either neglected or obscure. Few studies specify the time between the last clopidogrel ingestion and surgery.Several studies were keen on the blood loss and allogeneic transfusion in patients who received their last clopidogrel or asprin within 7 days prior to coronary artery bypass grafting. Concerning the secession of aprotinin and the increasing proportion of patients with persistence on clopidogrel until their surgery, evolutional work is expected, especially in the eastern population. The purpose of this study is to assess the effect of tranexamic acid in patients with clopidogrel and asprin ingestion less than 7 days prior to surgery. The working hypothesis is that tranexamic acid would reduce bleeding and transfusion requirements in this specific population of patients.
The purpose of this study is to test if an early appointment (within 10 days) when compared to a standard appointment (5 weeks) will affect attendance at the Cardiac Rehabilitation orientation and subsequent enrollment into cardiac rehabilitation.
The purpose of this study is to investigate the effect of combined glucagon-like-peptide-1 (GLP-1) analogue and metformin therapy on glucose metabolic and cardiovascular endpoints compared to metformin monotherapy in patients with coronary artery disease (CAD) and newly diagnosed type 2 diabetes (T2D). It is hypothesized that GLP-1 analogue added to backbone therapy of metformin in CAD patients with T2D will improve beta-cell function, left ventricular ejection fraction (LVEF), heart rate variability and lower 24h blood pressure among other selected endpoints. The present study on CAD patients with newly diagnosed T2D will address these selected endpoints during an investigator initiated, randomized, double blind, crossover, placebo-controlled 12 + 12 weeks intervention study with a 2 week wash-out period.
This prospective, randomized trial will compare the extent of covered stent strut segments by assessed by Optical Coherence Tomography (OCT) of the ORSIRO DES with that of the XIENCE PRIME DES, which is the standard of choice of contemporary drug eluting stents (DES).
This is a prospective, multi-center study examining the clinical impact of the Corus CAD (Age/Sex/Gene Expression score - ASGES) assay in approximately 250 evaluable subjects with no history of obstructive coronary artery disease who now present with chest pain or anginal-equivalent symptoms to a primary care physician (PCP) for evaluation.
This study is being done to demonstrate a powerful new method for detecting heart disease that combines the proven prognostic capability of exercise stress testing with the superior image quality of Cardiac Magnetic Resonance Imaging (CMR). The investigators hope to demonstrate that exercise CMR has equivalent or superior diagnostic accuracy compared to exercise stress SPECT for detecting obstructive artery disease.
