Active clinical trials for "Heart Failure"

The idea behind the Future Patient research project is to develop a telerehabilitation program and tools for patients with heart failure. The hypothesis for this study is that participation in a telerehabilitation program for patients with heart failure will increase the patients' quality of life and multi-parametric (subjective and objective) individualized monitoring in a telerehabilitation program for patients with heart failure will increase detection of worsening of symptoms and avoid future hospitalization of the HF-patients.

The aim of our prospective randomised study is to assess the efficacy of the retrograde application of non-selected bone marrow autologous cells concentrate (BMAC) in patients with heart failure with reduced ejection fraction of left ventricle (HFREF) of ischemic aetiology. The evaluated preparation is concentrated BMAC, obtained using Harvest SmartPReP2 technology.

Holding ACEI/ARBs during initial 72 hours of admission with acute decompensated heart failure may help preserve renal function with a lesser decline in GFR. This treatment modification will also allow the option of aggressive diuresis in volume overloaded CHF patients which should result in a lesser decline of AKI, length of stay, readmission rates, and cost associated with CHF treatment.

The pathophysiology of heart failure with preserved ejection fraction (HFpEF) is complex and multifactorial. Chronotropic incompetence has emerged as a crucial mechanism, particularly in elderly patients. Betablockers, drugs with negative chronotropic effect, are commonly used in HFpEF, despite current evidence does not support its routine use in these patients. The aim of this work is to evaluate the effect of betablockers withdrawal in patients with HFpEF and chronotropic incompetence on functional capacity assessed by the peak oxygen consumption at maximal exercise (peakVO2) at 15 and 30 days after the intervention

While preliminary data show that oral nicotinamide riboside (NR) supplementation increases myocardial levels of oxidized nicotine-adenine dinucleotide (NAD+) levels in mice, there has been no direct evidence that suggests oral NR increases NAD+ levels or improves mitochondrial function in human hearts. This Pilot Study is designed to obtain feasibility data for a planned, larger study testing the hypothesis that oral NR supplementation will increase myocardial NAD+ levels and improve cardiomyocyte mitochondrial function in participants with advanced heart failure planned for elective left ventricular assist device (LVAD) implantation. To demonstrate safety and feasibility of NR in this patient population, the investigators propose to enroll 5 participants planned for LVAD implantation in a Pilot Study of NR in which participants will receive NR, up-titrated over 3 days to a final NR dose of 1000mg twice daily. Blood and myocardial tissue analyses collected previously from age- and gender-matched LVAD recipients will serve as controls.

Effects of ferric carboxymaltose single HD (1000 mg) infusion upon FGF23 in patients with isolated HFREF compared to patients with HFREF+CKD (all pts with iron deficiency). This study aims at identification of the optimal target population for a follow-up ("main") study.

This study evaluates the safety and physiologic effects of increasing dietary potassium intake in individuals with heart failure.

The purpose of the LEVEA study is to assess the performances of a new automatic left ventricular auto threshold (LVAT) algorithm (In-Clinic LVAT algorithm) when used by physicians during in-hospital follow-up.

Nearly 80% of acute heart failure (AHF) patients admitted to the hospital are initially treated in the emergency department (ED). Once admitted, within 30 days post-discharge, 27% of patients are re-hospitalized or die. Attempts to improve outcomes with novel therapies have all failed. The evidence for existing AHF therapies are poor: No currently used AHF treatment is known to improve outcomes. ED treatment is largely the same today as 40 years ago. Congestion, such as difficulty breathing, weight gain, and leg swelling, is the primary reason why patients present to the hospital for AHF. Treating congestion is the cornerstone of AHF management. Yet half of all AHF patients leave the hospital inadequately decongested. The investigators propose a novel approach to aggressively decongest patients in the ED setting: lung ultrasound guided, protocol driven, AHF management. LUS B-lines are a measure of extra-vascular lung water (EVLW). In the setting of AHF, LUS B-lines are a measure of congestion. This simple, easily learned technique has excellent reliability and reproducibility. The investigators hypothesize that a strategy-of-care will outperform usual care. At the present time, usual care is largely empirical. This study will improve the evidence base for ED AHF management. This proposed pilot study, if successful, will lead to an outcome trial examining whether an ED AHF strategy-of-care increases days alive and out of the hospital for patients.
