Filter by:This is a limited safety and feasibility study to evaluate the PVSS Introducer and Paracor Ventricular Support System when used to treat patients with heart failure. The implant, which is loaded onto the delivery system, is placed over the epicardial surface of the right and left ventricles. No formal hypothesis testing will be performed; descriptive statistics will be used to summarize patient outcomes. The results of the study will be used to guide the design and sample size estimation of future studies.
The main purpose of this study is to see if the experimental drug ZP120, when given with the approved drug furosemide to patients with acute or sub-acute heart failure, can reduce the amount of fluid in the patients' lungs and make breathing easier.
The purpose of the OMNI study is to characterize therapy and diagnostic utilization in study participants implanted with study devices and to describe Implantable Cardioverter Defibrillator(ICD)therapy utilization for life threatening arrhythmias in primary and secondary prevention study participants. This study will assess therapies in Medtronic pacemaker, defibrillator, and cardiac resynchronization therapy devices. The first therapy is for reducing unnecessary pacing in pacemaker patients. The second therapy provides pacing therapy in an attempt to stop fast or life threatening ventricular arrhythmias in lieu of delivering a defibrillation shock. The third therapy is a diagnostic measurement of a patient's fluid status and provides the physician information on the patient's heart failure status. The study will also assess the time to a patient's first defibrillation shock and will verify that the shock was for a fast or life threatening ventricular rhythm.
The impact of nesiritide in CHF is unclear, but it is possible that systemic vasodilation leads to adverse consequences even if the direct renal effects are positive. Therefore, this study will look at the effects of direct intrarenal administration of nesiritide on GFR and RPF.
Anthracycline-based chemotherapy is a key point of the treatment of patients with Hodgkin's and non-Hodgkin's lymphomas. However, cumulative doses are limited by cardiotoxicity, resulting in a marked left ventricular function impairment that may lead to heart failure. The standard clinical approach to monitoring for anthracycline cardiotoxicity is based on cardiac function monitoring using echocardiography or radionuclide angiography. The aim of this study is to evaluate the usefulness of biochemical markers of cardiac injury (troponin and NT-proBNP) and structural changes on cardiac MR in predicting anthracycline cardiotoxicity.
Heart failure induces modification in several neurohormonal systems. The aim of this study is to determine if the growth hormone/IGF1 axis is modified in heart failure patients compared to healthy volunteers.
The goal of X-Change HF is to estimate the effect of biventricular stimulation in patients who need antibradycardia ventricular stimulation (more than 80%); are eligible for the exchange of an old pacemaker or implantable cardioverter defibrillator (ICD); and have ventricular dysfunction (left ventricular ejection fraction [LVEF] < 35%). All patients eligible for participation in the study will be upgraded with a cardiac resynchronization therapy (CRT)-device and receive either right ventricular or biventricular stimulation in a crossover protocol. The endpoint is functional performance measured by spiroergometry.
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).
The purpose of this study is to determine whether a larger dose of the aldosterone antagonist spironolactone combined with a lower dose of an ACE inhibitor is more effective in reverse left ventricular remodeling in severe congestive heart failure in patients with nonischemic cardiomyopathy.
This study will evaluate the efficacy and safety of angiotensin converting enzyme inhibition (ACE-I) therapy for the treatment of mitral regurgitation (MR).
