Active clinical trials for "Cardiomyopathy, Dilated"

This study aims to determine the effect of Coenzyme Q10 supplementation on conventional therapy of children with heart failure due to idiopathic dilated cardiomyopathy.

The purpose of this study is to determine the safety and clinical effectiveness of umbilical cord mesenchymal cells transplanted by intravenous infusion in patients with heart failure.

Recent data suggest that areas of fibrosis and hibernating myocardium develop in patients with non ischemic dilated cardiomyopathy. Ranolazine is a new drug, developed to releave symptoms of angina in patients with stable coronary disease that is not suitable for surgical or percutaneous revascularization. It has been shown that in patients with stable coronary disease Ranolazine improves myocardial perfusion as shown with myocardial nuclear imaging. The aim of this trial is to evaluate effects of ranolazine on myocardial perfusion in patients with dilated cardiomyopathy.

The technique of transplanting progenitor cells into a region of damaged myocardium, termed cellular cardiomyoplasty1, is a potentially new therapeutic modality designed to replace or repair necrotic, scarred, or dysfunctional myocardium2-4. Ideally, graft cells should be readily available, easy to culture to ensure adequate quantities for transplantation, and able to survive in host myocardium; often a hostile environment of limited blood supply and immunorejection. Whether effective cellular regenerative strategies require that administered cells differentiate into adult cardiomyocytes and couple electromechanically with the surrounding myocardium is increasingly controversial and recent evidence suggests that this may not be required for effective cardiac repair. Most importantly, transplantation of graft cells should improve cardiac function and prevent adverse ventricular remodeling. To date, a number of candidate cells have been transplanted in experimental models, including fetal and neonatal cardiomyocytes5, embryonic stem cell-derived myocytes6, 7, tissue engineered contractile grafts8, skeletal myoblasts9, several cell types derived from adult bone marrow10-15, and cardiac precursors residing within the heart itself16. There has been substantial clinical development in the use of whole bone marrow and skeletal myoblast preparations in studies enrolling both post-infarction patients, and patients with chronic ischemic left ventricular dysfunction and heart failure. The effects of bone-marrow derived mesenchymal stem cells (MSCs) have also been studied clinically. Currently, bone marrow or bone marrow-derived cells represent highly promising modality for cardiac repair. The totality of evidence from trials investigating autologous whole bone marrow infusions into patients following myocardial infarction supports the safety of this approach. In terms of efficacy, increases in ejection fraction are reported in the majority of the trials. Non-ischemic dilated cardiomyopathy is a common and problematic condition; definitive therapy in the form of heart transplantation is available to only a tiny minority of eligible patients. Cellular cardiomyoplasty for chronic heart failure has been studied less than for acute MI, but represents a potentially important alternative for this disease.

The purpose of this study is to examine the the effect of the HMG-CoA reductase inhibitor Rosuvastatin on left ventricular remodeling in patients with dilated cardiomyopathy.

This is a pilot study to evaluate the feasibility and safety of the Algisyl-LVR™ device. The purpose of this study is to investigate Algisyl-LVR™ employed as a method of left ventricular restoration in patients with dilated cardiomyopathy who are scheduled to undergo routine open heart surgery. Algisyl-LVR™ will be injected into the myocardium under direct visualization during the surgical procedure. This clinical evaluation is intended to provide the initial evidence of the safety and feasibility of the device as well as the procedure used to deploy the device. The results of the initial trial will also help to establish the utility of various assessments in evaluating and following the effects of the device.

Nesiritide is a rapid vasodilator that mimics the action of an endogenous hormone - human B-type natriuretic peptide (BNP). BNP is produced naturally in the ventricles of the heart in response to stretch. Nesiritide decreases systemic vascular resistance (SVR), pulmonary capillary wedge pressure (PCWP), right atrial pressure (RAP), and mean pulmonary arterial pressure. Nesiritide does not affect the heart rate, but does increase the stroke volume and consequently cardiac output, resulting in a decrease in the symptoms of decompensated heart failure. It is generally well tolerated, with the major negative side effect being hypotension. When compared to standard therapy consisting of dobutamine and nitroglycerin, nesiritide had similar vasodilatory effects, but showed a lower incidence of arrhythmia. Nesiritide has been approved for IV treatment of patients with acutely decompensated congestive heart failure. Although studies have tested the effectiveness and safety of nesiritide in adult CHF patients, this has not been done in children. Subjects enrolled in this study will be pediatric (<21 years) patients carrying a diagnosis of dilated cardiomyopathy with decompensated congestive heart failure. The standard of care for these patients is to undergo cardiac catheterization with placement of a Swan-Ganz catheter for hemodynamic monitoring. Subjects will be randomly assigned to receive either Nesiritide or placebo (5% Dextrose). The infusion will then be continued for a total of twenty-four hours. During this one day period, measurements of systemic blood pressure, central venous pressure (right atrial pressure), pulmonary capillary wedge pressure, cardiac output, mixed venous saturation, pulmonary vascular resistance, and systemic vascular resistance will be measured at regularly scheduled intervals. The Swan-Ganz catheter will remain in place for 2 hours after the discontinuation of study drug, and then removed. The objectives of this study are: To assess the efficacy of Nesiritide therapy in decreasing the pulmonary capillary wedge pressure, right atrial pressure, and systemic vascular resistance in children with dilated cardiomyopathy. To assess the efficacy of Nesiritide in decreasing pulmonary edema and increasing cardiac index in the above mentioned population. To assess the safety of both bolus administration and continuous infusion of Nesiritide in children with dilated cardiomyopathy. To assess the pharmacokinetics of Nesiritide in this population.

The pathogenesis of dilated cardiomyopathy (DCM) leading to heart failure is closely associated with autoimmunity dysfunction. A few studies represented that Qiliqiangxin capsule, a Chinese medicine, could enhance heart function in chronic heart failure and regulate the balance of TNF-a and IL-10 in myocardial infarction. In this study, to explore the effects of Qiliqiangxin capsule on the improving heart function and immunoregulation in patients with DCM, patients were recruited, anti-heart autoantibodies and some representative cytokines were assayed by enzyme-linked immuno sorbent assay (ELISA), and the efficacy of heart function improvement was compared between Qiliqiangxin capsule and placebo under the standard treatment of DCM.

Background: Honey, as a natural product produced by honey bees, has anti-oxidant, anti-microbial, anti-inflammatory and immunomodulator properties. A few reports suggest that honey might have positive effects on cardiovascular diseases. Methods: This was a randomized controlled study, which was carried out on 50 children, aged 2 to 12 years, suffering from idiopathic dilated cardiomyopathy (IDC). Patients were randomly assigned into two equal groups: the honey group and the control group. In the honey group, honey was provided in a dose of 1.2g/kg/day for three months in addition to the traditional treatment of IDC. The patients in the control group received only their standard treatment, without honey. The main outcome measure was the percent change in the ejection fraction (EF) and the fraction shortening (FS) shown in echocardiography.

A phase 1 prospective study to determine the procedural feasibility and safety and preliminary efficacy of intracoronary infusion of cardiosphere-derived cells (CDCs) in patients with dilated cardiomyopathy.
