Ketone Ester for Treatment Of Acute Heart Failure

Ketones have been suggested to have significant physiological effects in patients with heart failure. Potential mechanisms for these effects include energy provision for the failing heart and direct protective effects on other organs. Despite the strong physiological rationale, the acute effects of ketone therapy in patients with acute heart failure (AHF) is unclear. AHF is a major healthcare issue, with in-hospital mortality exceeding 10%. Therefore, we propose a vanguard randomized controlled trial to assess the effects of ketone esters in patients with AHF. Sixty patients hospitalized with AHF will be randomized to receive either 25 grams of ketone esters three times per day or a matching placebo for five days, or until death or hospital discharge. We hypothesize that ketone therapy will improve markers of systemic congestion and heart failure symptoms. Primary endpoint will be changes in NT-proBNP levels during therapy. Secondary endpoints will be KCCQ scores, and hemodynamic profile as assessed by echocardiogram. Exploratory endpoints will clinical outcomes including mortality, need for intensive care unit admission, among others.

Infusion of Furosemide to Improve Diuretic Efficiency in Acute Heart Failure

Acute heart failure is a condition where the heart suddenly cannot pump blood well enough for the body's needs. Many people admitted to the hospital with acute heart failure have too much fluid in the body. This can cause shortness of breath, swelling, and the need for treatment with water-removing medicine. Furosemide is a commonly used water-removing medicine that is given into a vein to treat fluid overload. It can be given in different ways. One way is as a continuous infusion, where the medicine is given slowly over time through a pump. Another way is as repeated injections given several times a day. It is not known whether one of these ways is better than the other for removing excess fluid in people with acute heart failure. The purpose of this study is to compare two ways of giving furosemide into a vein: Continuous infusion started with an initial extra dose, and bolus injections given three times a day. About 436 adults admitted to hospitals in Denmark with acute heart failure and fluid overload will take part. Participants will be randomly assigned to one of the two treatment groups. This means that chance will decide which treatment method each participant receives. The main thing the researchers will measure is how much body weight participants lose about 3 days after randomization. Weight loss is used as a measure of how much excess fluid has been removed.

MRI Assessment of Pulmonary Edema in Acute Heart Failure

Researchers are testing a more accurate way to measure how much fluid is in the lungs (also called pulmonary edema, or "increased lung water") in people with Heart Failure (HF) using MRI (Magnetic Resonance Imaging). There is little known about the exact level of lung water in patients with AHF or how these levels change from the time of hospital admission to discharge. The purpose of this research study is to measure the lung water in patients hospitalized for HF, to determine the change in lung water over the course of hospitalization and treatment, and to find out if lung water levels can predict if patients are higher or lower risk for returning to the hospital or dying from heart failure.

Optimized Treatment of Pulmonary Edema or Congestion

Background: Intravenous (IV) loop-diuretics have been a key component in treating pulmonary edema since the nineteen sixties and has a Class 1 recommendation in the 2021 European Society of Cardiology guidelines for heart failure. Conversely, vasodilation was downgraded in the treatment of acute heart failure due to a lack of trials that compare vasodilation with loop-diuretics in a hyperacute clinical setting. This clinical equipoise will be tested in a trial including patients with pulmonary congestion immediately at hospital admission. Primary objective: To determine the superior strategy of loop-diuretics (furosemide), vasodilation (nitrates) or the combination during emergency treatment. Design: Investigator-initiated, randomized, double-blinded, placebo-controlled trial with 1:1:1 allocation. Intervention: Intervention-phase will last 6 hours from study-inclusion, and patients will be allocated to one of three groups: * Boluses of 40 mg IV furosemide + nitrate-placebo as soon as possible and repeated up to 10 times. * Boluses of 3 mg IV isosorbide dinitrate + furosemide-placebo as soon as possible. * Boluses of both 3 mg IV isosorbide dinitrate + of 40 mg as soon as possible.

Pharmacological Optimization in Prevention in Heart Failure: A Sex-gap?

The goal of this clinical trial is to learn whether a rapid and intensive optimization of heart failure medications in women can improve outcomes after hospitalization for heart failure. It will also investigate the safety and the tolerance of these treatments when given at full guideline-recommended doses. The main questions it aims to answer are: 1. Does intensive medication optimization reduce death or hospital readmissions for heart failure within one year? 2. Do women benefit as much as men from intensive and full-dose heart failure therapy? 3. Is this treatment protocol safe and feasible also in women? Researchers will compare two groups of women hospitalized for heart failure: * High-intensity care: starting and increasing all recommended heart-failure medications as quickly as possible and monitoring patients closely during the first weeks after discharge. * Usual care: medications are started and adjusted gradually, according to the judgment of the treating cardiologist and the patient's usual care team. The study will follow participants for 12 months to see whether the high-intensity strategy reduces death, hospital readmission for heart failure, or worsening symptoms. It will also evaluate side effects, medication tolerance, and quality of life. Participants will be randomly assigned to one of the two groups, attend regular follow-up visits for one year, complete a short quality-of-life questionnaire (EQ-5D). This study will include about 360 women from 13 hospitals in Italy. It is sponsored by IRCCS Policlinico San Donato and funded by the Italian Medicines Agency (AIFA).

The Role of intraABDOminal Pressure and Point Of Care UltraSound to Guide Decongestive Therapy in Heart Failure

Systemic venous congestion is the primary therapeutic target of intravenous loop diuretics in patients admitted for acute heart failure (AHF). Despite their utility, a significant proportion of AHF patients are discharged with persistent clinical symptoms of congestion (residual congestion). Therefore, in recent years, there has been a growing focus on the use of tools (biomarkers, clinical ultrasound) that allow us to optimize diuretic treatment and thereby improve the prognosis of AHF patients. The objective is to analyze whether the strategy of guiding intravenous loop diuretic dosing based on intra-abdominal pressure(IAP) measurements and clinical ultrasound is superior to the conventional strategy employed in daily clinical practice. This study is a randomized, multicenter clinical trial involving consecutive patients admitted with a diagnosis of AHF in the Internal Medicine and Cardiology departments. Patients who meet the inclusion criteria, after signing informed consent, will be randomized into two groups: 1) Diuretic treatment guided by usual clinical practice and 2) Treatment guided by intra-abdominal pressure levels and clinical ultrasound (inferior vena cava and portal Doppler). This strategy will be maintained during the first 72 hours of admission, with a thorough analysis of congestion and diuretic response being conducted.

Optimal Diuretic Therapies for Acute Heart Failure With Volume Overload

Aim to identify the best strategy for treating acute heart failure (AHF) with volume overload, particularly focusing on patients resistant to standard loop-diuretics. The trial is a double-blinded, randomized, controlled, multicenter study. Its primary objective is to compare the efficacy of loop-diuretics combined with either Metolazone or Acetazolamide, against loop-diuretics alone. The trial will also determine the optimal type of loop-diuretic to use. Eligible participants include adults over 18 years hospitalized with AHF and volume overload, showing signs of congestion and at risk of diuretic resistance. Exclusions apply to those with acute coronary syndrome, low systolic blood pressure, prior renal therapy, or previous treatment with Acetazolamide or Metolazone. The primary outcome is the number of days alive and out-of-hospital by day 30. Secondary outcomes include a composite clinical benefit at 30 days, Kansas City Cardiomyopathy Questionnaire (KCCQ) scores, and successful decongestion 72 hours post-inclusion. The trial aims to enroll about 1,041,939 patients across three treatment arms over three years. The minimal important difference is set as a reduction in out-of-hospital days by at least two days, with an anticipated low dropout rate. The study's power is calculated to be 80% with an adjusted alpha level for comparing the three diuretic groups.

Prognostic Markers of Acute Heart Failure With Chronic Kidney Disease

Acute heart failure (AHF) is defined as new or worsening of symptoms and signs of heart failure and is the most frequent cause of unplanned hospital admission in elderly patients. N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is one of the most developed prognostic markers for AHR patients and. NT-pro-BNP has limitations in terms of diagnostic or predictive accuracy in patients with chronic kidney disease (CKD). Plasma proteomics have the potential to examine underlying pathophysiological and prognostic roles, so we compared the plasma proteomic signature to predict outcomes of patients with or without CKD hospitalized for AHF.
