Active clinical trials for "Heart Failure"

The SynCardia 70cc temporary Total Artificial Heart (TAH-t) is approved by the U.S. Food and Drug Administration (FDA) for use as a bridge to transplant for patients at risk of imminent (about to happen) death from irreversible biventricular heart failure. The purpose of this research study is to evaluate whether the TAH-t can support patients with life-threatening irreversible biventricular heart failure who are not eligible for transplantation. The TAH-t, when used for patients who are not eligible for transplant, is considered to be an investigational (not approved by FDA) use. This use is called destination therapy (DT). Nineteen (19) patients with life-threatening, biventricular failure who are not eligible for cardiac transplant will be enrolled in the Primary Arm of the study and followed for up to six months post-TAH-t implant. Safety will be evaluated by reviewing the adverse events that are experienced by the enrolled subjects and comparing them to previous experience of TAH-t patients who were waiting for a heart transplant. Since approximately 74% of patients with this condition would not be expected to live beyond six months, the benefit of the TAH-t for DT will be confirmed based on survival to six months without experiencing permanent disabling stroke-related deficits. After the six month follow-up visit, patients will continue to be followed under the study for up to five (5) years postTAH-t implant [every six months for up to two years while supported with the TAH-t implant and then annually for another three years]. Up to an additional 19 patients may be enrolled in the Secondary Arm of the study to further characterize the use of the TAH-t for DT in a broader patient population. Follow-up would be the same for patients enrolled in both arms of the study.

Ivabradine acts by inhibiting the ionic If current that modulates the pacemaker activity of sinoatrial node cells. The aim of present study is to evaluate the efficacy and safety of IvabRadine hemisulfate Sustained-release Tablets versus placebo in patients with moderate to severe chronic systolic heart failure.

Phase I study in healthy adult male and female volunteers to compare the bioavailability of enalapril administered in orodispersible Minitablets with or without water in comparison to the standard galenic tablet formulation of enalapril. The standard pharmacokinetic parameters will be calculated from the bioanalytical results for enalapril and enalaprilat and compared in a descriptive statistical analysis.

The purpose of this study is to investigate the non-inferiority of bisoprolol to carvedilol by evaluating tolerability (The probability that administered maintenance dose reaches the maximum will be determined as an indicator) as a primary endpoint when bisoprolol or carvedilol is administered for 48 weeks to Japanese chronic heart failure patients. In addition, the safety and efficacy of bisoprolol will be investigated.

The purpose of this study is to evaluate the efficacy and safety of recombinant human B-type natriuretic peptide (rhBNP) on heart and renal function in patients with acute decompensated heart failure (ADHF) and acute renal injury (AKI).

Background Heart failure is the final consequence of various heart disease and is also the leading cause of mortality worldwide. Diastolic dysfunction refers to an abnormality of diastolic distensibility, filling, or relaxation of the left ventricle. Patients with hypertensive left ventricular hypertrophy and an echocardiogram showing a normal ejection fraction and abnormal left ventricular filling can be said to have diastolic dysfunction. If pulmonary edema or effort dyspnea developed in such a patient. The term diastolic heart failure would be appropriate. Pathology leading to diastolic heart failure include: impaired relaxation, increased passive stiffness, endocardial and pericardial disorders, microvascular flow and neurohormonal regulation. Among them, the association of pro-inflammatory system and diastolic dysfunction are already established. The investigators therefore hypothesized that the change of serum inflammatory markers might be associated with the change of left ventricular diastolic function and the investigators thus conducted a randomized case-control trial with this regard. Method and materials This is a case-control randomized study. The definition of left ventricular diastolic function is according to Guideline from the ACC and AHA. The investigators will evaluate left ventricular diastolic function noninvasively by echocardiography before and after the intervention. Exclusion criteria include coronary artery disease, significant valvular heart disease, cardiomyopathy, pericardial disease and renal insufficiency. The investigators would like to enroll 50 cases and the same numbers of the controls. The inclusion criteria are subjects who underwent peritoneal dialysis at the investigators hospital for more than 6 months with higher pro-inflammation serum cytokine levels (C-reactive protein > 0.2mg/dL). Atorvastatin (40mg/day) would be given to those who were allocated to the intervention group. The investigators will than follow up cardiac diastolic function by echocardiography and also the change of serum markers. The investigators would also genotype the inflammation-associated genes and their promoter region and find the association between genetic polymorphisms and the treatment effects of statins.

The purpose of this study is to determine whether cholecalciferol supplementation in patients with chronic heart failure and low vitamin D levels improves: performance at six minutes walking test echocardiographic parameters neurohormonal imbalance

The purpose of this study is to determine the effect of a 4-week treatment period with GW501516X on how the heart obtains and uses energy. The energy of the heart will be measured by Magnetic Resonance Imaging (MRI). This study will also measure a number of other potential markers of drug activity, including levels of certain lipids (fats) and proteins in your blood. The data from this study may help researchers better understand the actions of this drug in the body and if this drug may be useful to treat patients with heart disease.

This is a double-blind, placebo-controlled, cross-over study evaluating the effects of UDCA on peripheral blood flow and immune function in patients with stable chronic heart failure (CHF). Sixteen patients with CHF will be recruited from the heart failure clinic at the Royal Brompton Hospital. Following baseline evaluation, patients will be randomised to receive either placebo or UDCA at a dose of 1000 mg/day for a period of four weeks. They will then undergo repeat evaluation (peripheral blood flow and immune function). A four week washout period will then take place before the patients cross-over to receive the respective other therapy for a further four weeks (i.e. those first receiving placebo will go onto receive UDCA and vice versa). The study will be completed after a total of twelve weeks, with a final assessment (peripheral blood flow and immune function).

Currently, the majority of heart failure patients who qualify for and receive a cardiac resynchronization therapy (CRT) device feel better than before their implant. However, there are some patients who do not improve after the implant. Michigan Heart is sponsoring a research study called LOCATE-Pilot to help understand whether the information from an echocardiogram, performed before implanting the CRT device, improves patients' responses to CRT. This is being done by evaluating your heart's function with an echocardiogram, to measure your heart's response during therapy. The study hypothesis is that response to CRT may be optimized by guiding left ventricular lead placement to the maximally delayed, viable basal segment of the left ventricle.
