Active clinical trials for "Heart Failure"

The purpose of this study is to assess the efficacy, tolerability and safety of dronedarone versus placebo in patients with symptomatic congestive heart failure (CHF) and left ventricular dysfunction (LVD) when added to evidence based treatments for CHF.

EffecT is a prospective, randomized multicenter study to assess whether management of atrial fibrillation (AF) as well as the early optimization of cardiac resynchronization therapy (CRT) via Home Monitoring decreases mortality and morbidity compared to conventional treatment in subjects with a standard indication for CRT with Implantable Cardioverter Defibrillator (ICD) backup and AF.

The idea of this study is to compare different ways of setting up a pacemaker, using blood tests to give us information about how well it's working. We hope to learn if we can use this approach to figure out the best pacemaker setup ("programming") for each individual patient. The setting we propose to adjust is the timing between the impulse sent between top and bottom chambers.

The main purpose of this study is to examine the effect of add-on therapy with the direct renin inhibitor Aliskiren in comparison to placebo on renal blood flow in patients with heart failure and reduced renal function. Primary outcome measure: change in renal blood flow at 6 months Secondary outcome measures: changes in renal function, N-terminal pro Brain natriuretic peptide, left ventricular function, blood pressure and neurohormones

The role of continuous positive airway pressure (CPAP) in cardiac function in patients with CSA and OSA has been studied with varying results. Nevertheless, it is not clear whether CPAP treatment for respiratory sleep disorders in CHF could slow down deterioration or improve the cardiovascular function. In an attempt to yield further insight into this subject, we undertook a multicentre study to analyze the role of CPAP therapy (optimal vs sham) in the LVEF and in other cardiac measurements in patients with CHF.Aim. We evaluated in a randomized multicentre placebo (sham-CPAP) controlled study the effect of CPAP treatment on the left ventricle ejection fraction (LVEF) among other cardiological related variables.

The DOT-HF trial is an international, prospective, multi-center, randomized, controlled trial.

The purpose of this study is to determine if patients in the HeartNet Ventricular Support System with optimal medical and device therapy arm (Treatment group) show statistically significant improvement compared to patients in the optimal medical and device therapy alone arm (Control group) after 6 months of follow-up.

To conduct a pilot study to evaluate the feasibility of a large randomized controlled trial (RCT) of metformin in patients with heart failure and type 2 diabetes and to generate initial morbidity and mortality estimates in this patient population. The primary hypothesis is that subjects with heart failure and type 2 diabetes who receive metformin will have a significant reduction in the combined endpoint of all-cause mortality and all-cause hospitalization as compared to subjects who receive placebo therapy.

Heart failure is a condition in which the heart is unable to pump enough blood to the body's other organs. A heart transplant may be necessary for some individuals with end-stage heart failure. Left ventricular assist devices (LVADs) can assist the heart in pumping blood, and are commonly used until a donor heart becomes available. Bone marrow cells injected into the heart may improve heart function and may lead to earlier LVAD removal. The purpose of this study is to evaluate the safety and effectiveness of injected bone marrow cells in improving heart function in individuals with LVADs who are awaiting heart transplants.

This research study is being performed to find out more information about the safety and effectiveness of injecting bone marrow progenitor cells (BMPCs) from one's own hip bone into one's heart muscle. The BMPCs are the cells from which the different types of blood and other cells grow. In patients with heart failure, the heart muscle does not pump well. Over a period of years, this continues to get worse until the patient dies of heart failure. The investigators are trying to find out if the injection of these BMPCs can make a change in the functioning of these areas of the heart muscle. Data from studies around the world have suggested that when patients with heart failure receive these cells by direct injection into their hearts they show signs of recovered heart function, however, there has been no evidence from actual studies of the cells of the patient's hearts to show how this process works. It is the investigator's plan to inject an eligible participant's heart with cells that are from one's own bone marrow during an operation to receive a ventricular assist device (VAD) or partial artificial heart and then to study the function of the heart while awaiting a heart transplant. The investigators will then examine the heart after it has been removed as part of the regular heart transplant operation for any microscopic changes (changes too small to be seen by the unaided eye but large enough to be studied under a microscope) at the site where the cells are injected. Participants will have no change in the chances of receiving a heart transplant by agreeing to participate in this study. There will also be no delay in receiving a VAD operation while waiting to participate in this study. This Phase I study has been cleared by the Food and Drug Administration (FDA) to enroll and treat patients. The Center for Biologics Evaluation and Research Investigational New Drug number (IND BB #) is 12304. (A Phase I trial is a research study using techniques or products in the first-stage or for the first time in human subjects).
