Active clinical trials for "Heart Failure"

Background: Acute heart failure is a potentially life-threatening condition, reaching mortality rates of up to 50% in advanced cases. The investigators have shown that infusion of ketone bodies increase cardiac output by 40% in stabile patients with chronic heart failure. However, there are no data showing the effects of ketone on patients with acute heart failure Objectives: To investigate the effect of ketone supplementation in patients with acute heart failure and cardiogenic shock, using two different types of oral ketone supplements. Methods: The investigators will conduct four randomized placebo-controlled studies, to investigate the hemodynamic effect of exogenous ketones in acute heart failure and cardiogenic shock. Perspectives: The present study will determine the potential beneficial effects of ketone supplements in patients with acute heart failure.

This is a prospective, multi-center, unblinded, randomized, controlled, and non-inferiority study comparing the EVA2 LVAS to the most recent magnetically levitated centrifugal LVAS (HM3 LVAS).

Diabetes mellitus people have a higher incidence of cardiovascular disease, and the results of cardiovascular events are worse. Heart failure and diabetes both have a worse prognosis, with a 1.5-2 times increased risk of death. Data from the literature have shown that MET lowers mortality by 14-35% in this patient population, which represents one-third of all HF patients with no increases in lactic acidosis incidence.

Our goal of the study is to learn the effects of the diabetes medication named Pioglitazone, in type-2 diabetic obese participants with Heart failure. The main question it aims to answer are: To demonstrate that impaired mitochondrial function leading to reduced ATP generation plays a key pathophysiologic role in the development of heart failure with preserved ejection fraction (HFpEF) in obese type 2 diabetic (T2D) individuals. To demonstrate that pioglitazone, improves diastolic (as well as systolic) function by improving myocardial insulin sensitivity and by reducing both myocardial and epicardial fat content.

The study compares standard right ventricle apical pacing with so called His-bundle pacing, for patients with slightly or moderately reduced ejection fraction and atrioventricular block requiring pacemaker therapy. The primary outcome is left ventricular ejection fraction measured after 6 months.

The purpose of this study is to test whether a ketone ester drink will improve exercise in people with heart failure (HF) compared to a placebo. In HF, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. There may be several reasons why these symptoms occur. There is some evidence that in addition to problems with the heart, patients with HF also have problems with their arteries and muscles that affect their ability to exercise. Ketones have been shown to improve exercise capacity in healthy volunteers, which may be related to effects on the heart function or on muscles. An infusion of ketones through an intravenous (IV) line has also been shown to significantly improve heart function, but whether a drink can produce similar improvements in HF patients is not known. This drink has been given status by Food and Drug Administration as "generally regarded as safe". The use of DeltaG in this study is experimental. DeltaG has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study.

The Korea HM3 PMS is a prospective, single arm, open-label, multi-center, post market surveillance is designed to evaluate clinical and functional outcomes with the HM3 LVAS as a treatment for advanced heart failure. The PMS will enroll up to 300 patients, that meet the Health Insurance Review and Assessment (HIRA) guidelines for LVAD implantation, from up to 25 sites in South Korea. Subjects who will be implanted but not included in the PMS can be enrolled retrospectively after obtaining their informed consent. The surveillance period for this PMS is expected to be 4 years from the time of HM3 approval in Korea, concluding on June 2, 2024.

This study will look at how participants' daily life is affected by their heart failure. The study will also look at the change in participants' body weight. This study will compare the effect of semaglutide (a new medicine) compared to "dummy" medicine on body weight and heart failure symptoms. Participants will either get semaglutide or "dummy" medicine, which treatment participants get is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach area, thigh or upper arm. During the study participants will have talks with the study staff about healthy lifestyle and physical activity. The study will last for about 59 weeks, that is a little more than 1 year. Participants will have 12 clinic visits with the study doctor. At 6 of the visits participants will have blood samples taken. At 5 of the visits participants will be asked to fill in a questionnaire At 4 of the visits participants will have to do a 6-minute walking test At 3 of the visits participants will have a test to check the heart. participants will have their eyes checked before or at the start of the study and at the end of the study Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

The present study will examine the comparative effectiveness of two treatment strategies currently used in the treatment of patients with systolic heart failure presenting with pleural effusion. Patients will be randomized to standard medical treatment only or medical treatment and referral to thoracentesis. Study hypothesis: A strategy of referring patients with heart failure-related pleural effusion to thoracentesis increases number of days alive outside of hospital over the following 90 days.

Rationale: Atrial fibrillation (AF) and heart failure (HF) can cause each other and sustain each other. Combined, the two diseases negatively influence each other's prognosis and lead to higher mortality. Studies in HF patients in which the AF burden is reduced by AF ablation show promising results toward improved prognosis, but so far only one randomized trial is conducted that focused on major clinical endpoints. As the selected patients in this trial were not representative for the entire population and its ablation method varied from patient to patient, it is the aim of the present study to confirm that early invasive therapy consisting of a strict pulmonary vein isolation (PVI) protocol using cryoballoon therapy has positive effects on hard clinical endpoints in a wider variety of patients in the HF population. Furthermore, there are no studies which compare cost-effectiveness of an early invasive strategy in this patient category. The investigators expect that avoided hospitalizations and healthcare resource utilizations lead to lower costs in the AF ablation group, despite initial higher costs of the procedure. Objective: To compare outcome and cost-effectiveness of early AF ablation by PVI using cryoballoon therapy with standard (medical) therapy in patients with heart failure with reduced ejection fraction. Study design: Multicenter, randomized, open label clinical trial. Study population: Symptomatic adult patients with heart failure with reduced ejection fraction (<40%) and paroxysmal or persistent AF. Intervention: AF ablation (PVI) using cryoballoon therapy. Outcome measures: The primary endpoint is a combined endpoint of all-cause mortality, unplanned cardiovascular hospitalization, and stroke (time-to-event analysis). Secondary endpoints of the trial are: A combined endpoint of mortality, number of unplanned cardiovascular hospitalizations, and stroke (recurrent-event analysis); A hierarchical endpoint of mortality, unplanned cardiovascular hospitalizations, stroke, and HF complaints; Cost-effectiveness. Key exploratory endpoints include individual components of the combined endpoints, days alive out of the hospital, hospitalizations for heart failure, recurrence of atrial arrhythmia, and quality of life.
