Active clinical trials for "Heart Failure"

The purpose of this study is to compare three treatment modalities for central, or mixed obstructive and central, sleep apnea in patients with chronic heart failure and reduced ejection fraction. The modalities to be tested are nocturnal supplemental oxygen (NSO) and continuous positive airway pressure (CPAP). The main outcome measures will be left ventricular ejection fraction on echocardiogram and peak oxygen consumption on cardiopulmonary exercise testing.

The investigators aim to determine if patients with systolic heart failure treated with prasugrel achieve greater platelet inhibition compared to those treated with clopidogrel.

The purpose of this study is to determine whether the computerized decision support system 'NHGDoc' is effective in improving quality of primary care in terms of processes of care (e.g. prescribing behavior of physicians) as well as outcomes of care (e.g. hospital admissions, mortality).

The primary objective is to test the hypothesis that, compared with placebo, therapy with Subcutaneous (SQ) GLP-1 agonist in the post-Acute Heart Failure Syndrome (AHFS) discharge period will be associated with greater clinical stability at six months as assessed by a composite clinical endpoint.

The study objectives are to determine the effectiveness of structured access to a Wii game computer compared to motivational support only in heart failure patients on exercise capacity and daily activity. Secondly, to determine the effectiveness of structured access to a Wii game computer compared to motivational support only in heart failure patients on the combined endpoint of death, readmission and quality of life. The following research questions will be addressed: What is the effectiveness of structured introduction and access to a Wii game computer in patients with heart failure to improve their exercise capacity compared to patients with heart failure in a control group who only receive motivational support? What is the effectiveness of structured introduction and access to a Wii game computer in patients with heart failure compared to patients with heart failure in a control group who only receive motivational support to increase their daily physical activity, decrease health care use and improve quality of life? What are experiences of heart failure patients and how is their exercise motivation when they are introduced and instructed to play with a Wii game computer?

The ANTHEM-HF Study is designed to demonstrate the safety and efficacy of vagus nerve stimulation (VNS) with the Cyberonics VNS Therapy System for the treatment of subjects with symptomatic heart failure.

The purpose of this clinical trial is to determine whether intermittent administration of testosterone against placebo is associated with a reduction of mortality and heart failure hospitalizations at 1 year, in male patients with advanced heart failure and testosterone deficiency.

This study will examine the additional clinical benefit conferred by multipoint pacing (MPP) compared to standard CRT over a period of 3 months. Patients will be randomized to MPP ON vs. OFF and followed for a total of 6 months. This includes two crossover periods for each pacing modality (MPP on vs. off).

This study will evaluate the PaceSafe Right Ventricular Autothreshold (RVAT) and Left Ventricular Autothreshold (LVAT) features for AUTOGEN Cardiac Resynchronization Therapy Defibrillator (CRT-D) devices.

This study is the first administration of GSK2798745 in humans. This will be a sponsor un-blinded, placebo-controlled study to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of GSK2798745, given as single and repeat oral doses to healthy subjects and stable heart failure (HF) subjects. Approximately 28 healthy subjects will be enrolled in the study cohorts (Cohort 1-3) involving single and repeat dose escalations of GSK2798745, while up to 24 stable heart failure subjects will be enrolled in Cohort 4 involving single and repeat dose administration of GSK2798745, with the dose selected based on data from healthy subject cohorts. This would be followed by enrollment of up to 8 subjects with heart failure in Cohort 5 involving repeat dose administration of GSK2798745. The study duration, including screening and follow-up, is not expected to exceed 17 weeks for subjects in the study (in any cohort).
