Active clinical trials for "Heart Failure"

A Phase 1-2a Study of CXL-1020-01 in Patients with Stable Heart Failure

The PING-EP study is designed to evaluate electrode properties on phrenic nerve stimulation (PNS) in coronary sinus using a commercially available diagnostic electrophysiology catheter.

This study assess the safety/tolerability, PK/PD of LCZ696 in patients with stable heart failure.

The purpose of the study is to compare survival of both patients and newly transplanted hearts following heart transplantation among patients who were transplanted with donated hearts preserved on ice and those who were transplanted with donated hearts using the Organ Care System (OCS). The Organ care system preserves the hearts in a warm blood perfused beating state. The study also compares the number of rejection episodes, heart related adverse events, ICU time, and ventilation time between the two groups. The study is considered a success if survival in the OCS group was not inferior to the ice group.

A study to evaluate the effect of Atacand on patients with heart failure with depressed left ventricular function

The purpose of this study is to evaluate the effects of spironolactone and furosemide on insulin resistance in patients with chronic heart failure.

Heart failure affects over 5.3 million Americans and, while other cardiovascular diseases have enjoyed a reduction in mortality rates over the last decade, the mortality from heart failure continues to rise[1]. Thus, identifying novel therapies that can reduce heart failure development and/or progression are warranted. Unifying to most cardiomyopathic processes is an impaired handling of reactive oxygen species (ROS)[2-4]. Reactive oxygen species are generated as byproducts of inflammation and oxidative stress that occur in the setting of normal myocardial aerobic metabolism. Metallothionein, glutathione reductase, and superoxide dismutase are major antioxidants in the myocardium that help combat oxidative stress and prevent myocardial damage. In certain clinical settings, including cardiac ischemia, diabetes, and heavy metal excess (copper, iron), myocardial oxidative stress levels are greatly increased. When pro-oxidant levels exceed myocardial antioxidant capabilities, ROS-induced membrane, protein, and DNA inactivation can lead to the development of cardiac dysfunction. One means of preventing the development or progression of cardiomyopathy is to reduce oxidative stress through up-regulation of intramyocardial antioxidants. Murine studies of cardiomyopathy have shown that oral administration of zinc acetate may succeed as an indirect myocardial anti-oxidant because zinc sufficiently up-regulates the intramyocardial production of superoxide dismutase (a zinc-dependant anti-oxidant enzyme) and metallothionein (a "super antioxidant") [5-8]. Zinc also directly reduces prooxidant Cu levels by reducing gastrointestinal zinc absorption. However, to date, no studies have examined the impact of zinc acetate supplementation in subjects with cardiomyopathy and systolic failure on antioxidant capacity and remodeling. The hypothesis of this pilot study is that administration of oral zinc acetate to humans with cardiomyopathy will lead to an up-regulation of myocardial anti-oxidant capabilities,leading to a favorable reduction in oxidative stress. This study will provide preliminary data to support a randomized, placebo-controlled trial of zinc therapy in heart failure as a means of improving or preventing the progression of systolic dysfunction in subjects with mild-moderate heart failure.

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. The incidence and prevalence of AF increase exponentially with increasing age and AF is associated with higher mortality, more frequent hospitalization, and lower quality of life. Furthermore, AF is often associated with heart failure. The majority of AF is initiated by ectopic foci found primarily in the pulmonary veins. It was shown that catheter ablation of those veins could eliminate episodes of AF. In patients with heart failure, catheter ablation could improve cardiac function, symptoms and quality of life. It remains still unknown whether AF ablation is more effective than conventional treatment in terms of mortality and morbidity.

It is a single centre, randomised controlled study of the effect of NOGA-guided direct intramyocardial injection of mesenchymal stromal cells on the development of new myocardium and blood vessels in patients with heart failure. Stem cells will be obtained from the bone marrow and culture expanded for 6 - 8 weeks before injected into the myocardium. The patients will be followed with safety, clinical, MRI and CT endpoints for 1 year.

The CVRx® Rheos® Diastolic Heart Failure Trial is a prospective, randomized, double blind trial with up to 60 subjects conducted at up to five centers in Europe. All subjects will be followed up to one year post implant.
