Filter by:This study will explore the ability of an algae (ocean plant) omega-3 fat supplement (DHA) to reduce triglyceride levels in patients currently being treated with statin therapy (Zocor or simvastatin, Lipitor or atorvastatin, Pravachol or pravastatin, Crestor or rosuvastatin, etc.) for coronary artery disease(CAD)or risk equivalents (any of the following: heart attack, post angioplasty or stent, post coronary bypass surgery, angina, vascular disease, stroke or diabetes). The rationale for the study is based around the finding that patients with CAD have an approximately 20 % reduction in the risk of sudden death when treated with fish oil (DHA is one of the ingredients in fish oil). In studies of statin-based therapies, it has been observed that statins reduce the risk of coronary events 20-45%. There has not yet been research trials exploring the combination of the two ingredients (i.e., DHA plus statin) in patient treatment either to reduce recurrent cardiac events or to address another reported finding of fish oils to lower triglyceride levels (triglyceride is a form of "blood fat"). This research project will be a pilot project to assess the safety and effectiveness of DHA "add-on" therapy in patients currently being treated with statins for CAD. The study hypothesis is to test the effectiveness of DHA as compared to placebo to lower triglyceride levels in the blood. This is a double-blinded randomized clinical trial.
This is a dose ranging study to compare the effect of VIA-2291 vs. Placebo on various inflammatory biomarkers in patients with recent acute coronary events
The purpose of this study is to provide information of the relative potency of prasugrel and clopidogrel on platelet function studies, inflammation, and myocyte necrosis in subjects undergoing elective percutaneous coronary intervention (PCI).
The main aim of the study is to determine the effectiveness of an educational intervention designed to increase attendance of coronary artery bypass grafting (CABG) patients at Cardiac Rehabilitation Programs (CRPs) on actual CRP participation rate and; examine patient-related factors (demographic, health, psychosocial, awareness) influencing patients' attendance at CRPs. We hypothesized that the proportion of CABG patients participating in CRPs will increase significantly to 20-30% following the educational intervention employed.
The study has been designed to comparatively evaluate the safety and effectiveness of the PAS-Port Proximal Anastomosis System and conventional suturing techniques for creation of the connection between graft veins and the aorta in patients undergoing coronary artery bypass graft surgery for treatment of coronary artery disease. Patients in the study will have a coronary angiogram approximately 9 months following surgery to determine the patency of vein grafts created using either the automated PAS-Port or hand sewn methods. Safety will be evaluated by documenting the occurence of adverse clinical events and evealuating possible association with either method.
The aim of the DARE study is to see whether strict glycemic control during cardiac rehabilitation may ameliorate the improvement of exercise capacities (VO2 peak, peak workload, ventilatory threshold)in patients with type 2 diabetes with coronary artery disease.
PURPOSE OF STUDY Observational studies have demonstrated that elevated levels of plasma total homocysteine is a risk factor for cardiovascular disease. The purpose of this trial is to evaluate the clinical effects of homocysteine lowering treatment with B vitamins during 3-5 years follow-up of patients undergoing cardiac catheterization for suspected coronary artery disease (CAD). Special attention will be given to complication rates among patients needing subsequent percutaneous transluminal coronary angioplasty (PCI) or coronary artery by-pass grafting (CABG). HYPOTHESIS The primary hypothesis of this study is that, among patients with CAD, a daily supplement with B vitamins will reduce the risk for cardiovascular mortality and serious cardiovascular events with at least 20%. The secondary hypothesis of this study is that, among patients with CAD, a daily supplement with B vitamins will reduce the risk for total mortality, coronary events, cerebrovascular events and other cardiovascular events. The hypothesis will be tested for an effect of any of the treatments (folic acid / vitamin B12 or B6), and the effect will be evaluated according to initial total homocysteine levels and B vitamin levels as well as to the change in these levels after 1 and 6 months. The sample size has been calculated to 3088 patients using a two-sided chi-square test with significance 0.05 and at an 80% power level, presumed event rate of 22% over 4 years, and event rate reduction of 20%, adjusted for non-compliance/drop-out of 20%. STUDY DESIGN This is a controlled, double-blind two-centre trial with 3090 included men and women who underwent coronary angiography at Haukeland University Hospital or Stavanger University Hospital between April 1999 and April 2004. At baseline about 1300 patients underwent PCI and 600 underwent CABG. The patients were randomized into 4 groups in a 2 x 2 factorial design to receive one of the following four treatments: A, folic acid 0.8 mg plus vitamin B12 0.4 mg and vitamin B6 40 mg per day; B, folic acid 0.8 mg plus vitamin B12 0.4 mg per day; C, vitamin B6 40 mg per day; D, placebo. The active drug and the placebo tablets had identical appearance and taste. Treatment was started as soon as the patients were randomized after the coronary angiography procedure. The patients have been undergoing interviews, clinical examination and blood-sampling at baseline, at follow-up after 1 month and 1 year, and at a final study visit. In addition, information on dietary habits was obtained from 2400 patients at baseline. Among 350 patients that have undergone PCI at baseline, a full clinical examination, blood sampling and repeat coronary angiography to assess re-stenosis has been performed about 9 (6-12) months after the PCI procedure. For these patients, angiograms suitable for quantitative coronary angiography (QCA) analysis have been obtained at the baseline and follow-up invasive procedures. The follow-up was terminated ahead of schedule in October 2005 due to lack of compliance of the participants caused by media reports from the NORVIT study (NCT00266487) on potential increased cancer risk associated by B vitamin supplementation. The patients had then been followed for 1.5 - 5 years. STUDY END POINTS Primary clinical endpoints during follow-up are all cause death, non-fatal acute myocardial infarction, acute hospitalization for unstable angina and non-fatal thromboembolic stroke (infarction). Secondary endpoints are fatal and non-fatal acute myocardial infarction (including procedure related myocardial infarction), acute hospitalization for angina, stable angina with angiographic verified progression, myocardial revascularization, fatal and non-fatal thromboembolic stroke.
The overall goal of this study is to use MRI to: - Examine the relationship between known risk factors for cardiovascular disease and coronary artery wall thickness; - Examine the relationship between coronary artery wall thickness and other markers of subclinical coronary atherosclerosis, such as carotid wall thickness and coronary calcium scores; and, - Examine the feasibility of measuring the progression of coronary artery wall thickness over time in a subset of participants.
This 2 arm study will investigate the efficacy and safety of RO4607381 in patients with coronary heart disease, or CHD risk equivalent. After a pre-randomization phase of 5-12 weeks, patients will be randomized to receive either RO4607381 (900mg po) or placebo po daily for 24 weeks, with concomitant atorvastatin 10-80mg daily, and changes in cholesterol level and lipoprotein metabolism will be measured. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
To compare the efficacy of 16-row multi-detector CT (MDCT) with standard myocardial perfusion imaging in detecting coronary artery disease (CAD) in patients without a previously established diagnosis of CAD.
