Active clinical trials for "Heart Failure"

This is an open-label, non-randomized, pilot-study to evaluate the effect of Interleukin-1 blockade on exercise capacity in patients with heart failure. Subjects will undergo cardiopulmonary exercise testing at baseline and after 2-weeks treatment with anakinra (recombinant human Interleukin-1 receptor antagonist).

The objective of this post approval registry is to confirm the long-term safety and effectiveness of the Corox Over-the-wire (OTW) Steroid Left Ventricular (LV) lead as used in conjunction with a BIOTRONK cardiac resynchronization therapy defibrillator (CRT-D). The Corox OTW Steroid LV Lead is capable of providing permanent pacing therapy to the left ventricle in a CRT-D system. The following are the specific objectives to be evaluated during this post-approval registry: Long-term effectiveness of the COROX OTW Steroid in providing biventricular pacing Safety of the COROX OTW Steroid LV pacing lead

The purpose of this trial is to determine the safety and feasibility of the VentrAssist LVAD in providing circulatory support for patients who require an LVAD as a bridge to cardiac transplantation.

Torasemide is a loop diuretic (pyridine-sulfonylurea)with a wide experience in the treatment of oedema associated to heart failure, kidney or liver disease and either in the treatment of arterial hypertension (alone or combined with other anti-hypertensive drugs). It has been developed a new formulation of Torasemide (Torasemide prolonged release). The aim of this trial is to study the effects of Torasemide prolonged released in comparison with furosemide, in the reduction of myocardial fibrosis in patients with chronic heart failure (Class II-IV of the New York Heart Association Classification.

Cell transplantation for treatment of heart failure is a novel field of translational research that offers the perspective of developing curative approaches by regenerating or "rejuvenating" lost and/or diseased myocardium and inducing growth of new blood vessels. Based on the safety and preliminary efficacy testing in previous trials, a stringent efficacy testing will be performed in this study. Sixty patients who had myocardial infarction in the past and now need bypass surgery for ongoing coronary artery disease will undergo either bypass surgery and placebo treatment or bypass surgery and injection of CD133 bone marrow cells directly in the heart muscle. The study will be fully blinded, i.e. neither the patient nor the surgeon knows what substance is injected (placebo or cell product). Patients will be followed for 6 months and various heart function measurements will be performed.

The purpose of this clinical investigation (NCT00957073) is to continue long-term follow-up of device arm subjects enrolled in the HOPE4HF Trial, utilizing the BAROSTIM NEO™ LEGACY device for Implantable Pulse Generator (IPG) replacements.

In this study, TRV120027 (or a placebo) intravenous infusion will be given to people with heart failure to learn about the effects of TRV120027. The results of this study will help choose the proper range of TRV120027 doses to use in future research studies involving patients with acute decompensated heart failure.

Diastolic heart failure (also known as "heart failure with normal ejection fraction" or "heart failure with preserved ejection fraction") occurs even though the heart muscle's pumping function is normal. In many cases diastolic heart failure is related to stiffening of the heart and blood vessels in people who have high blood pressure. Current guidelines suggest that patients should limit the salt content of their diet, as too much salty food can cause fluid retention and other problems in diastolic heart failure. Studies in animals with diastolic heart failure suggest that antioxidant chemicals found in grapes can block some of the harmful effects of salty diets. Because it is often difficult for patients with diastolic heart failure to maintain a low salt diet, the investigators are researching the effects of the antioxidant properties of grape seed extract, a natural supplement made from grape seeds. The investigators hypothesize that supplementing the diet with grape seed extract (GSE) can decrease the levels of harmful chemicals and improve heart and blood vessel function in patients with diastolic heart failure and a history of high blood pressure. The University of Michigan research group plans to enroll 25 patients with a history of high blood pressure and diastolic heart failure in a research study. The study will assess the effects of GSE on hormones and other chemicals that can cause heart and blood vessel damage. The investigators will also study the effects of GSE on the ability of the blood vessels and heart muscles to relax at the proper time and speed. Finally, the investigators will observe how GSE affects participants' overall ability to exercise, quality of life, and blood pressure control. Study participants will be randomly assigned to take either GSE or placebo (looks like but does not contain GSE) capsules twice a day for six weeks. After a two-week break, all subjects will cross over to the opposite group of capsules for an additional six-week period. At the start of the study and at the end of each six-week time period study participants will have non-invasive heart and blood vessel testing, blood work and urine tests, and blood pressure monitoring.

Exercise oscillatory breathing (EOB) is a ventilatory abnormality that occurs in approximately 20% of heart failure (HF) patients and carries a very unfavourable prognosis. Pathophysiology seems quite complex and putative mechanisms include increased pulmonary capillary pressure and pulmonary vasoconstriction, circulatory blood-flow fluctuations in the pulmonary arterial system and instability of ventilatory control. Inhibition of the phosphodiesterase 5 (PDE5) isoenzyme favourably regulates pulmonary vascular tone and permeability through over signaling of the endothelial nitric oxide pathway. The investigators tested the hypothesis that sildenafil would reverse the EOB pattern in patients with HF and pulmonary hypertension.

The purpose of this study is to determine the safety and efficacy of a 24 hour infusion with levosimendan in patients with acute myocardial infarction and heart failure after acute percutaneous coronary intervention (PCI) treatment.
