Filter by:CHF patients will be monitored using EarlySense ES-16 device and will simultaneously fill diaries and log their weight daily. The data collected and analyzed by the ES-16 device will be correlated with the CHF status data.
Patients with NYHA FC II-III heart failure will be randomized in a cross-over fashion to 8 weeks of bumetanide versus furosemide therapy (equipotent dose), to test whether bumetanide therapy has a superior effect on insulin resistance compared to furosemide. Patients will be subject to a frequently sampled intravenous glucose tolerance test (FSIGT) with minimal model (MINMOD) analysis to assess insulin resistance and to a 6-minute walk test (6MWT) to assess functional capacity; patient recruitment and retention success, as well as medication adherence, will also be assessed.
The purpose of this study is to assess the impact of a multidisciplinary team clinic including a clinical pharmacist, a registered nurse (RN), dietician and physician providing short-term sub-acute management of patients with heart failure on patient outcomes and the quality of medication use. Patients being discharged from the emergency department with a diagnosis of heart failure will be eligible for this study. We believe that emergency room visits, hospitalization and deaths secondary to heart failure will decrease secondary to this program.
The purpose of this study is to determine if cell therapy with your own cells (autologous cells) delivered with a catheter to regions of the heart with poor blood flow will be safe and if it will improve your ejection fraction and heart failure symptoms.
Cardiovascular disease is the leading cause of death and disproportionately prevalent in patients with kidney disease. Spironolactone has been shown to improve survival in the general population with heart failure by up to 30%. We wish to study the safety and tolerability of aldosterone blockade with spironolactone on cardiac function in a high risk population of patients on hemodialysis. We will study and closely monitor subjects over a period of 12 months, during which they will be receiving spironolactone for a period of 6 months.
The purpose of the present prospective, randomized study is to investigate the clinical effectiveness of standardized left ventricular reconstruction surgery (LVR). In order to standardize the procedure, the operation will be performed with the Blue Egg, manufactured by BioVentrix, a subsidiary of CHF Technologies, Inc.
This trial will look at the effectiveness and patient acceptance of ultrafiltration therapy in an outpatient setting. The purpose of this study is to determine if ambulatory patients who suffer from heart failure and hypervolemia can be safely and effectively treated in an outpatient infusion clinic. The results from this trial will be useful in planning a larger, randomized trial comparing usual care and ultrafiltration for this patient population in similar ambulatory settings.
Many people in the UK have ischaemic heart disease. Insufficient blood supply to the heart muscle means that it functions inefficiently, and leads to symptoms of shortness of breath, chest pain and excess fluid in the body. Recently it has been shown that cells from the inside of bone are able to produce many different cell types. We are investigating a new treatment in which a patient's bone marrow cells are taken, and injected into the heart in an attempt to produce new blood vessels and heart muscle cells. This may lead to a new treatment for ischaemic heart disease.
This study will determine whether an acute infusion of intravenous allopurinol improves the inotropic response to dobutamine in patients with idiopathic dilated cardiomyopathy (DCM) as measured by cardiac magnetic resonance imaging (CMR).
The purpose of this study is to evaluate the safety and bioactivity of intramyocardial gene transfer using VEGF (vascular endothelial growth factor) in patients with ischemic heart failure. The research treatment of this CHF study will involve the use of an intramuscular injection with a catheter inserted in through the groin to transfer a type of DNA (phVEGF165 gene) to the wall of the heart. Genes (which are part of the DNA molecules) carry instructions to allow the cells to produce specific proteins. Gene transfer or treatment with DNA (a necessary part of all cells) is being studied for the treatment of patients with heart failure. This research therapy, which is experimental and not proven, is designed to try to grow new blood vessels to improve blood flow to areas of the heart that are not receiving enough blood. DNA is present in all cells and provides the instructions for making proteins. After delivering a piece of DNA containing the vascular endothelial growth factor 1 (VEGF-1) gene (the product being studied) into cells, the cells may produce a specific protein called vascular endothelial growth factor 1 (VEGF-1). Animal studies have indicated that the VEGF-1 protein may cause new blood vessels to grow. The Vascular Endothelial Growth Factor Gene (ph VEGF 165) is found on the VEGF DNA. Experiments performed in animals show that once in the heart wall, the DNA directs the cells of the heart muscle to make the VEGF protein. VEGF 165 is a protein that has been shown to stimulate cells (known as endothelial cells), which form the inner lining of blood vessels. This protein causes cells to divide and grow, thereby forming new blood vessels. It is anticipated that this new blood supply may help the heart pump the blood more effectively and relieve some heart failure symptoms. We do not yet have enough information to know what will happen in humans, that is why we are doing this research. After gene transfer we will begin a process to help move some of the stem cells from the bone marrow into the blood circulation. Subjects will be given the drug called G-CSF (a drug used to move cells from the bone marrow into the blood stream). Stem cells are young cells produced by bone marrow (the spongy cavity in the center of large bones) that can develop into blood cells or other types of cells. This medication triggers the movement of stem cells out of the bone marrow and into the blood stream. Before being released into the blood stream, stem cells receive signals that direct them to become specific types of cells such as CD34+ cells (endothelial progenitor cells). CD34+ cells that move to or are in the area of damaged heart tissue may promote growth of new blood vessels that supply blood and nutrients and thereby improve the chance of survival of heart tissue, improve heart function, and possibly have a long-term benefit. We will be recruiting 12 subjects for this study. There will be no randomization and no placebo group. Once eligibility in the research study has been determined all subjects will be treated with the VEGF and G-CSF.
