Active clinical trials for "Cardiomyopathy, Dilated"

This study describes a controlled randomized clinical trial to evaluate the efficacy of bone marrow derived stem-cell implants by minithoracotomy in patients with dilated cardiomyopathy and cardiac failure class III or NYHA.

The study is divided into 2 parts. In the first part, the safety of the gene transfer agent MYDICAR® will be evaluated. In the second part, the ability of MYDICAR® to improve heart function will be studied.

This study will investigate whether there is an association between insulin resistance and cardiac function in children with dilated or hypertrophic cardiomyopathy. This study will also investigate whether there is an association between FGF21 and cardiac function in children with dilated or hypertrophic cardiomyopathy and whether this is mediated through greater insulin resistance and/or through independent effects.

The purpose of this study is to optimize the complex treatment of chronic heart failure of non-ischemic etiology by supplementing umbilical cord mesenchymal stem cells to the standard drug therapy.

Up to 72 healthy volunteers will be given a single dose of MYK-491 or placebo and be monitored for safety and tolerability over a 7 day period.

This study is designed to assess the efficacy, safety and tolerability of ixmyelocel-T compared to placebo (vehicle control) when administered via transendocardial catheter-based injections to patients with end stage heart failure due to IDCM, who have no reasonable revascularization options (either surgical or percutaneous interventional) likely to provide clinical benefit.

Dilated cardiomyopathy (DCM) is a poorly understood cause of systolic heart failure and is the most common indication for heart transplantation worldwide. Despite advances in medical and device therapy, the 5-year mortality of patients with DCM remains high. Patients diagnosed of dilated cardiomyopathy with a NYHA functional class of II to IV and left ventricular ejection fraction(LVEF) <35% were selected for randomized controlled study of the efficacy and safety of high dose Renin-angiotensin system (RAS) inhibitor (benazepril or valsartan), in comparison with low dose RAS inhibitor(benazepril or valsartan) and standard beta-adrenergic blocker therapy (metoprolol). The primary endpoint was all cause death or admission for heart failure. Additional prespecified outcomes included all-cause death, cardiovascular death, all-cause admission, heart failure admission. Secondary cardiovascular outcomes included the changes from baseline to the last available observation after treatment in NYHA functional class, quality-of-life scores, LVEF, LVEDD, mitral regurgitation and wall-motion score index assessed by ECG. Adverse events were reported during in-hospital observation and follow-ups.

The primary objective of this study is to study the acute effects of angiotensin-converting enzyme inhibitor (ACEI) on systemic, pulmonary and cerebral blood flow in post bidirectional cavopulmonary connection (BCPC) patients.

This study is designed to assess the safety and tolerability of Cardiac Repair Cells (CRCs) compared to standard-of-care in patients with dilated cardiomyopathy (DCM).

Several studies have documented that transplantation of bone marrow-derived cells (BMC) following acute myocardial infarction is associated with a reduction in infarct scar size and improvements in left ventricular function and perfusion. The available evidence in humans suggests that BMC transplantation is associated with improvements in physiologic and anatomic parameters in both acute myocardial infarction and chronic ischemic heart disease, above and beyond the conventional therapy. In particular, intracoronary application of BMC is proved to be safe and was associated with significant improvement in the left ventricular ejection fraction (LVEF) in patients with chronic heart failure. In contrast to ischemic heart failure, the data on effects of BMC transplantation in patients with dilated cardiomyopathy are limited to pre-clinical studies. In a rat model of dilated cardiomyopathy, intramyocardial delivery of pluripotent mesenchymal cells improved LVEF, possibly through induction of myogenesis and angiogenesis, as well as by inhibition of myocardial fibrosis, suggesting that the beneficial effects of stem cell transplantation in dilated cardiomyopathy may primarily be related to their ability to supply large amounts of angiogenic, antiapoptotic, and mitogenic factors. Similarly, transplantation of cocultured mesenchymal stem cells and skeletal myoblasts was shown to improve LVEF in a murine model of Chagas disease. Study Aim: To define the clinical effects of BMC transplantation in dilated cardiomyopathy in a pilot clinical study investigating the effects of intracoronary CD34+ cell transplantation on functional, structural, neurohormonal, and electrophysiologic parameters in patients with end-stage dilated cardiomyopathy.
