Active clinical trials for "Heart Failure"

A randomized, double-blind, positive-drug parallel controlled, multicenter phase III trial of the efficacy and safety of S086 tablets in patients with chronic heart failure with reduced ejection fraction (HFrEF)

Beta-blockers improve clinical outcomes in heart failure and reduced ejection fraction (HFrEF); but not in those with preserved EF. Global longitudinal strain (GLS) is a prognostic factor independent of left ventricular ejection fraction (LVEF). In a retrospective with 1969 patients with HF and LVEF of ≥40%, beta-blocker was associated with improved survival in those with low GLS (GLS <14%), but not in those with GLS ≥14%. In this prospective, randomized clinical study, the investigators will assess the effect of slow-release carvedilol in patients with HFpEF and hypertension. The primary endpoint is the time-averaged proportional changes in NT-proBNP level and GLS change from baseline to month 6.

This study looks at the effects of weight loss in people who have heart failure with reduced ejection fraction (HFpEF) and are overweight or obese. The main questions it aims to answer are whether weight loss in this group of people improves: The heart's shape and how well it pumps blood The person's quality of life and how much they can exercise Participants will attend 2 study visits, separated by 3-6 months. The intervention period takes place in between the 2 study visits. Each study visit may involve measurements including: Symptom and quality of life questionnaires Body measurements such as height and weight Blood tests Ultrasound scans of the heart (echocardiogram) Magnetic Resonance Imaging (MRI) scans of the heart 6 minute walk test Participants are randomly allocated (in other words, by lottery) to either 'diet' or 'control' groups. The control group will continue standard care. The diet group will be enrolled in a weight loss program supervised by the study team. Participants in the diet group will replace their usual meals with meal replacement products specifically designed to deliver a low calorie diet for weight loss. The products will consist of formula soups, shakes and porridges. This diet would last 8 weeks, followed by a guided period of food reintroduction and maintenance.

The aim of this study is to assess the efficacy, safety and cardiovascular outcomes of Sodium-glucose transport protein 2 inhibitors (SGLT2i) therapy in patients with heart failure reduced ejection fraction ( HFrEF) with and without diabetes mellitus and is to evaluate short-term effect of these drugs using the cardiac biomarkers Neopterin.

The Enavogliflozin Outcome Trial in Functional Tricuspid Regurgitation (EVENT) was designed to examine the hypothesis that, compared with placebo, therapy with the SGLT2 inhibitor enavogliflozin would improve clinical and echocardiographic outcomes in heart failure (HF) patients with functional tricuspid regurgitation (TR) and preserved left ventricular ejection fraction (LVEF). The primary objective of the EVENT study is to test the hypothesis that, compared with placebo, therapy with enavogliflozin for 18 months would improve a composite of cardiovascular events or worsening of TR on follow-up echocardiography in HF patients with functional TR and preserved LVEF. The secondary objective is to examine whether enavogliflozin is effective in reduction of renal events and tricuspid regurgitation, and to evaluate whether beneficial effects of enavogliflozin on primary outcomes are associated with reduction of all-cause mortality.

Intravenous (IV) loop diuretics have been a key component in treating pulmonary edema since the 1960s and has a Class 1 recommendation in the 2021 guidelines for acute heart failure. However, no randomized clinical trials have investigated loop diuretics versus other interventions for acute heart failure, and clinical knowledge of the hemodynamic effects of furosemide is based in studies from the 1970s. In this study, we aim to assess the acute effect of furosemide on cardiac filling pressures and pulmonary congestion. Hypothesis: Administration of furosemide induces a hyperacute (within 30 minutes) lowering of cardiac filling pressures and pulmonary congestion before significant diuresis occurs. Design: A prospective, interventional study including 20 patients admitted due to a clinical diagnosis of acute heart failure with pulmonary congestion. Intervention: 80 mg of furosemide is administered IV. Measurements include blood pressure, peripheral oxygen saturation, pulmonary fluid content by ReDS*, ultrasound examination of heart and lungs, and assessment of cardiac filling pressures with doppler and strain analysis. Measurements are repeated at several time points until 6 hours have passed.

To investigate whether an early supported discharge strategy for patients admitted to hospital because of HF, using a pH neutral subcutaneous (SC) furosemide formulation (SQINFurosemide) at home (delivered by non-CE marked SQINInfusor), compared to a usual care strategy with intravenous (IV) furosemide in hospital, results in an increased number of days spent alive and out of hospital (DAOH) at 30 days.

Cardiac Resynchronization Therapy (CRT) decreases heart failure hospitalizations and mortality and increases left ventricular Ejection Fraction (EF) in patients with dilated cardiomyopathy, left bundle branch block and QRS duration >130msec. His bundle pacing has a similar effect in this category of patients. However, CRT is not beneficial in heart failure (HF) patients with narrow QRS. His-bundle pacing delivers physiological ventricular activation and has been shown to improve acute hemodynamic function in patients with heart failure, a prolonged PR interval, and either a narrow QRS or RBBB through AV delay optimization. We observed an acute hemodynamic effect during application of higher pacing output (3.5 Volts/1 msec) in HF patients with dilated or ischemic cardiomyopathy and narrow QRS independently of the paced QRS duration or AV delay shortening. This is a multi-center, prospective randomized single-blinded study, recruiting a sub-population of patients with heart failure (dilated or ischemic cardiomyopathy, EF<50%, narrow QRS (<110 msec), in optimal medical treatment who have an indication for ICD.

The study objective is to evaluate the feasibility of the Doraya Catheter and measure clinical performance and safety endpoints, in ADHF patients deemed to have insufficient diuretic response.

The objective of the EpiCANS study is to evaluate the technique of stimulation of the cardiac autonomic nervous system (SNAC) directly at the epicardial level in humans during heart surgery. Proof of concept study
