Active clinical trials for "Heart Failure"

Heart failure with normal ejection fraction is often under diagnosed and certainly under treated in hemodialyzed patients. Because of the benefit of reducing heart rate, ivabradine, a pure heart-rate lowering agent without effects on blood pressure, is of potential therapeutic utility.

The main purpose of this research is to determine whether injecting mesenchymal precursor cells (MPC) into the heart during surgery to implant a left ventricular assist device (LVAD) is safe. MPCs are normally present in human bone marrow, and have been shown to increase the development of blood vessels and new heart muscle cells in the heart. In addition, this research is being done to test whether injecting the MPCs into the heart is effective in improving heart function.

The purpose of this study is to evaluate the safety and performance of the MediGuide™ system during CRT implants.

This is a single-center, open label phase II study to evaluate the effect of inhaled nitrite delivered in a dose escalation manner on the change in pulmonary vascular resistance (PVR) in subjects with pulmonary hypertension undergoing right heart catheterization. A total of 50 subjects with a confirmed diagnosis of pulmonary hypertension and meet all inclusion/exclusion criteria will be enrolled in the study which will entail a single right heart catheterization and nebulized nitrite dose of 45mg with one subsequent dosage of 90 mg.

The purpose of this study is to determine the benefits and safety of intravenous administration of low dose nesiritide or low dose dopamine in patients with congestive heart failure and kidney dysfunction. There is a substudy in a subset of subjects that is being used to determine whether the Provocative Dyspnea Severity Score (pDSS) is a more sensitive index of variability in clinical status than the dyspnea VAS assessed without standardization of conditions at assessments.

The primary objective of this feasibility study is to provide clinical data to demonstrate the safety and activity of a concentrate of nucleated cells from bone marrow aspirate (BMAC) produced with the Harvest Bone Marrow Aspirate Concentrate System for treating patients diagnosed with congestive heart failure (CHF).

Type 2 diabetes (T2D) is a major risk factor of chronic heart failure (CHF). Glycemic control in patients with the combination of T2D and CHF is complicated and the currently available treatments have proven to be inadequate in clinical trials. Objectives To investigate the effect of Liraglutide compared to placebo on left ventricular ejection fraction (LVEF) in CHF patients with and without T2D. Multicenter, randomized, double blind study of 240 patients with documented systolic CHF (50% with T2DM) will be randomised. The effect of Liraglutide on left ventricular systolic and diastolic function will be evaluated by advanced echocardiography Primary outcome parameter is change in LVEF from visit 1 to week 24.

This study aims to identify the relationship between a low-sodium diet and neurohormonal and clinical status in stable chronic HF patients.

The purpose of this study is to examine the efficacy of three doses of prednisone, a glucocorticoid, in treatment of patients with symptomatic heart failure.

Heart failure is a chronic condition in which the heart fails to function as a pump to move blood around the body. This sets up a complex physiologic response to compensate, which include activation of many hormonal mechanisms which result in fluid accumulation. In recent years, medications to block the hormonal response to heart failure are given as standard drugs, and these include ACE inhibitors, and beta blockers. Mortality is reduced with these medications, as well as symptoms improved. Medications that were traditionally used in heart failure include diuretics, which cause fluid loss, and digoxin, which causes the heart to pump harder. These medications were introduced before clinical trials as we know them now were run. Since the introduction of ACE inhibitors and beta blockers, it is not clear whether there is still a role for digoxin. In this study, we plan to withdraw digoxin from patients with stable heart failure in normal rhythm, taking stable doses of ACE inhibitors and beta blockers, in a closely monitored environment and watch for the effect of this on heart failure.
