Active clinical trials for "Heart Failure"

The aim is to provide evidence of the long-term benefits of personalised pacemaker programming on heart function and battery longevity. This will be achieved by showing in a single centre, phase II, double-blind, randomised, placebo-controlled trial that reducing the amount of pacemaker beats to a minimum reverses these changes and extends battery life.

This is an open-label, single-center study to examine distinguishing features of the structure and function of the oral and gut microbiome in healthy adult normal volunteers compared to volunteers with PH-HFpEF in the breakdown of oral nitrate.

This pilot will enroll 50 HF patients (age ≥ 75 years) undergoing CRT device implantation at the hospitals of the University of Pittsburgh Medical Center, Duke University, Ohio State University, and the VA Pittsburgh Healthcare System. Patients will be randomized to CRT-P versus CRT-D and followed until study end. Rates of patient screening, enrollment, randomization, and retention as well as cost of care will be examined. The results of this pilot study will inform the design of a large pivotal non-inferiority trial and will be necessary for its success. Patients who refuse participation in the randomized pilot trial will be asked to enroll in a prospective observational cohort. Characteristics of patients who choose CRT-P vs. CRT-D will be compared and patients' level of satisfaction with their device decision will be measured.

Heart failure (HF) is a major health problem worldwide but there is no global HF study that documents demographics, socioeconomic and clinical factors, diagnostic and management patterns, etiology, biomarkers, co-morbidities, treatments, quality of life, barriers to care and outcomes in all parts of the world. Such knowledge is essential in the prevention and treatment of this global disease. The Global Congestive Heart Failure Registry (G-CHF) is a global registry of approximately 20,000-25,000 HF patients enrolled over approximately 5 years to study these risks and causes of HF.

TEMA-HF 1 Long-Term Follow-up study is a follow-up study of TEMA-HF 1. It assessed the long-term impact of a 6-months telemonitoring program in chronic heart failure patients.

To confirm the non-inferiority of OPC-61815 16-mg injection to tolvaptan 15-mg tablet using as the primary endpoint the change in body weight following 5-day intravenous administration of OPC-61815 16-mg injection or 5-day oral administration of tolvaptan 15-mg tablet to CHF patients with volume overload despite having received diuretics other than vasopressin antagonists

After the implantation of a left ventricular assist device (LVAD), many patients continue to experience exercise intolerance. LVAD echo guided optimization (EO) determines a more favorable hemodynamic profile and could provide an improvement on functional capacity (FC). VAFRACT is a prospective randomized trial to evaluate the additional benefit of an EO approach on FC, measured by cardiopulmonary exercise test (CPET), in LVAD optimization free population.

STRATS-AHF (STrain for Risk Assessment and Therapeutic Strategies in patients with Acute Heart Failure) registry enrolled 4,312 patients hospitalized for acute HF from 3 tertiary university hospitals (Seoul National University Bundang Hospital, Seoul National University Hospital, and Chungnam National University Hospital) from January 2009 through December 2016.

The study is a randomized controlled pilot trial to evaluate whether withdrawal of spironolactone is safe and associated with re-deterioration of left ventricular function in patients with heart failure with improved ejection fraction. The aim of current trial is to test the hypothesis that withdrawal of spironolactone would not be associated with relapse of significant clinical deterioration of left ventricular systolic function.

Diuretic therapy is first-line treatment for acute decompensated heart failure. However, accurate assessment and management of patient blood volume is challenged by the limitations of physical exam and surrogate markers for blood volume. The study primary objective is to determine if goal-directed care as quantified by direct Blood Volume Analysis (Daxor BVA-100™) in addition to usual care results in more appropriate treatment and consistent achievement of euvolemia.
