Active clinical trials for "Heart Failure"

The purpose of this study is to determine whether allopurinol is effective in relieving symptoms of patients with heart failure and high blood uric acid levels.

The purpose of the study is to test whether Cognitive Behavior Therapy (CBT) plus heart failure self-care education is superior to "usual care" for depression.

The purpose of this study is to evaluate the effects of oral lixivaptan capsules in patients with congestive heart failure.

The renin-angiotensin system (RAS) is a regulatory system that plays an essential role in patients with chronic heart failure (CHF). Plasma renin activity (PRA) is a strong and independent predictor of outcome, also in the presence of ACE inhibitors (ACE-i) and/or angiotensin receptor blockers (ARBs). Recently, it has been shown that vitamin D regulates renin transcription by activating the vitamin D receptor (VDR). Thus, specific activation of the VDR represents a novel target for therapeutic intervention in CHF. Currently, clinical data are lacking. The investigators aim to investigate the effect of the administration of vitamin D in patients with CHF.

The purpose of this study is to determine the effect of remote ischemic preconditioning on exercise capacity in patients with heart failure.

In this double blinded study patients with resynchronization pacemaker- AICD were assigned to Omega3 and placebo randomly, results indicated that Omega3 had no more effect than placebo in mortality, BNP level and 6 minutes walk test.

The purpose of this study is to investigate the safety, tolerability, pharmacodynamics (how the study medication affects the body) and pharmacokinetics (how the drug is absorbed in the body, how it is distributed within the body and removed from the body over time) of an intravenous administration of JNJ-39588146 or placebo over a 3-hour period in patients with heart failure. The highest tolerated dose received during the first 3 hours of the study will be administered to some patients for an additional 18 hours. There will be up to 3 doses given throughout the administration period over a total of up to 21 hours.

The objective of this study is to compare two different strategies of disease management in heart failure patients treated with cardiac resynchronization therapy devices Remote monitoring with CareLink Network System Standard management of the disease by means of scheduled routine in-patient follow-ups; and to demonstrate that the remote monitoring strategy is superior to the standard strategy, both in terms of clinical effectiveness and total healthcare system utilization.

The purpose of this study is to determine if the delivery of cells just after implantation of left ventricular assist device will help to improve the pumping function of your heart and minimize heart enlargement in the future. The cells will be obtained by aspiration or withdrawal of fluid from your bone marrow from your pelvic bone using a needle and syringe. This would not take place until 24-48 hours prior to your planned left ventricular assist device implantation. During the surgery the surgeons will inject the prepared cells that were taken from your bone marrow and inject it into your heart muscle. This study will test whether receiving your own bone marrow cells directly into your heart will help your heart to recover function after placement of a left ventricular assist device.

When implantable cardiac defibrillators are implanted (ICDs), the defibrillation threshold (DFT), of the amount of energy required to effectively terminate life-threatening arrhythmias is determined. The device is then programmed to discharge a larger amount of energy in order to provide a safety margin. In some patients, the DFT is so high, that an adequate safety margin is not programmable. Placement of a defibrillation lead in the azygos vein has been found to be helpful in these patients. This goal of this trial is to attempt to quantify the average reduction in the DFT (if any) that results from the addition of the azygos lead.
