Active clinical trials for "Heart Failure"

Purpose: The purpose of the study is to examine if treatment with liothyronine increases left ventricular ejection fraction (LVEF) in patients with stable, chronic heart failure.

The purpose of this study is to demonstrate that cardiac resynchronization therapy (CRT) responder rate can be improved by 3-dimensional (3D) echo-guided left ventricular (LV) lead placement compared to traditional LV lead placement.

This project, using home monitoring for the signs and symptoms of heart failure, aims to empower patients to be actively involved in their care and provide rapid access to healthcare services and advice when needed. The telemonitoring system is easy to use and ensures the accurate transfer of information from the home to the hospital. The information is then screened and if important changes are seen, the patient will be contacted by a heart failure nurse who will offer advice and may arrange a clinic visit or suggest alterations to the medication. The project uses modern technology to provide disease management, links the patient in their home with the hospital and reinforces education and self-care behaviour. This innovative programme will be tested to see if it reduces the risk of re-admission to hospital, reduces anxiety, improves quality of life following a hospital admission for heart failure and whether this represents good value for money in terms of the health benefits it provides. Hypothesis: Patients using home telemonitoring of signs and symptoms of heart failure following discharge from hospital with chronic heart failure have a reduced risk of all-cause re-hospitalisation when compared with usual care.

The purpose of this study is to determine if treating anemia with subcutaneous erythropoetin in patients with heart failure and a preserved ejection fraction (HFPEF) will be associated with reverse ventricular remodeling, significant improvements in exercise capacity, and improved health status, as compared with placebo.

Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are changes in the heart beat sometimes an implantable heart device is used to control the rate and rhythm of the heart beat. The purpose of the REVERSE clinical trial is to determine whether pacing in both the left and right ventricles using Cardiac Resynchronization Therapy (CRT) can help slow the progression of heart failure in people who have mild or previous symptoms and poor heart pumping function. This kind of therapy has previously been shown to reduce symptoms and improve exercise capacity in people with more advanced forms of heart failure.

The purpose of the study is to evaluate the benefit of interventricular (V-V) delay optimization in reducing the non-responder rate in patients with cardiac resynchronization defibrillator (CRT-D) devices. The primary endpoint of this study is CRT responder rate. For patients enrolled with new CRT-D systems, patients are considered non-responders if BOTH of the following requirements are fulfilled: < 10% improvement in 6-minute hall walk, and no class improvement or worsening in New York Heart Association (NYHA) scale. For those receiving CRT-D devices as replacements of older CRT-D systems, patients are considered non-responders if BOTH of the following requirements are fulfilled: > 1 heart failure (HF) related hospitalization, and no class improvement or worsening in NYHA scale.

The purpose of this study is to determine whether combined mortality and hospitalization in heart failure patients receiving optimal pharmacologic therapy can be reduced by combining optimal pharmacologic therapy and 1) biventricular pacing therapy alone or 2) biventricular pacing with defibrillation.

The MADIT-CRT trial is designed to determine if combined implantable cardiac defibrillator (ICD)-cardiac resynchronization therapy (CRT-D) will reduce the risk of mortality and heart failure (HF) events by approximately 25%, in subjects who are in New York Heart Association (NYHA) functional Class II with non-ischemic or ischemic cardiomyopathy and subjects who are in NYHA functional Class I with ischemic cardiomyopathy, left ventricular dysfunction (ejection fraction [EF] < or = 0.30), and prolonged intraventricular conduction (QRS duration > or = 130 ms).

Chronic heart failure (HF) is a syndrome of impaired ventricular function resulting in clinical symptoms of fatigue, dyspnea, and decreased exercise capacity. These symptoms lead to a cyclical pattern of an increasing sedentary lifestyle with accompanying deconditioning and deterioration of muscle function. Until recently, the prescription for individuals with HF was rest and minimization of physical exertion.

The researchers hypothesize that the addition of nesiritide to standard therapy will prevent worsening of renal function in patients admitted to the hospital with decompensated heart failure and renal dysfunction relative to standard therapy alone.
