Real-world Effectiveness and Safety of Savagen (Sacubitril/Valsartan) in Malaysian HFrEF Patients

This multicentre, prospective, single-arm cohort study will evaluate the real-world effectiveness and safety of Savagen, an NPRA-approved generic sacubitril/valsartan, in Malaysian adults aged 18 to 70 years with heart failure with reduced ejection fraction (HFrEF; LVEF ≤40%, NYHA class II-III). Approximately 80 patients initiating Savagen as part of routine clinical care at hospitals offering a Heart Failure Medication Therapy Adherence Clinic (HFMTAC) will be followed for 12 months. The primary outcome is the change in NT-proBNP from baseline to 12 months. Secondary outcomes include changes in LVEF, renal function (serum creatinine, eGFR), serum potassium, patient-reported health status (KCCQ) and dietary diversity (Dietary Diversity Score), a composite of cardiovascular death or first heart failure hospitalisation, and adverse events, including hypotension, hyperkalaemia, renal impairment and angioedema. The study does not aim to establish equivalence with the reference product; it will generate local real-world evidence on the effectiveness, tolerability, safety and patient-reported outcomes of generic sacubitril/valsartan in routine Malaysian HFrEF care.

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).

Vericiguat and Reverse Remodeling Indices in Heart Failure

The goal of this clinical trial is to investigate how vericiguat benefits adults with stable heart failure with reduced ejection fraction (HFrEF) who are already receiving guideline-directed medical therapy. The main questions are: * Does vericiguat improve right ventricular systolic function, measured by fractional area change (FAC)? * Does vericiguat favourably influence myocardial remodeling, fibrosis, angiogenesis, inflammation, metabolism, renal function, and hematologic balance? * Do genetic and oxidative stress profiles modify treatment response? Researchers will compare a group receiving vericiguat plus usual care with a group receiving usual care alone to assess structural, functional, and biomarker changes over 12 months. Participants will: * Have blood drawn at baseline and follow-up visits for biomarker, metabolomic, genetic, transcriptomic, and hematologic analyses, including platelet function testing * Perform oral glucose tolerance tests (OGTT) to assess insulin resistance * Undergo echocardiography, cardiac magnetic resonance imaging, and cardiac scintigraphy to evaluate heart structure, function, and perfusion * Attend follow-up visits at 1, 3, 6, and 12 months Open-label extension: After the 12-month randomized phase, participants originally assigned to usual care will be offered open-label vericiguat and followed for an additional 12 months. This exploratory extension will reassess study outcomes to evaluate the consistency and magnitude of response to vericiguat in the prior control cohort.

Telemonitoring of HFrEF Patients

The aim of this study is to find out whether remote health monitoring can help people with chronic heart failure. For 3 months, some patients use a SiDLY CARE PRO electronic wristband. It measures their physical activity, blood oxygen level and heart rate every 15 minutes. The information is sent electronically to a secure database. The study includes two groups of patients. One group uses the wristband and receives regular cardiology care. The other group receives regular care without remote monitoring. During the study, patients have three visits at the cardiology clinic. Their health, heart failure symptoms and treatment are assessed. They also complete short questionnaires about their quality of life and ability to perform everyday activities. The researchers compare the two groups to see whether remote monitoring is associated with better health and fewer hospital stays or deaths related to worsening heart failure. The study began in February 2023 and is planned to continue until 31 December 2028.

IRONICA: IRON Repletion In Heart Failure - A Comparison of Oral and IV Approaches

The goal of this clinical trial is to learn which iron treatment works better for adults with congestive heart failure and low iron levels: intravenous (IV) iron given through a vein or oral (PO) iron taken by mouth. Participants must have heart failure with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF) and a transferrin-saturation (TSAT) level below 20 percent. The main questions the study will answer are: 1. Does IV iron raise walking distance on a 6-minute walk test more than oral iron after 24 weeks? 2. Does IV iron improve symptoms and quality of life more than oral iron? 3. How do the two treatments compare for safety, side effects, and hospital readmissions/ mortality? Researchers will compare IV ferric carboxymaltose with oral ferrous sulfate to see which option helps people feel and function better. What participants will do * Be randomly assigned by (like flipping a coin) to IV iron or oral iron. * Receive either a one-time IV iron infusion (with possible repeat at 12 weeks) or take iron pills twice each day for 24 weeks. * Visit the infusion clinic at 6 weeks for second dose of IV iron if needed. * Visit the clinic at 12 weeks for a follow-up to gather follow-up data including 1. A 6-minute walk test 2. Brief symptom and quality-of-life surveys 3. Blood tests to measure serum iron, ferritin, and transferrin saturation This study will help doctors decide whether IV or oral iron is the safer, more effective way to treat iron deficiency in people with heart failure in our local community.

Implementation of an Encounter-based Patient Decision Aid for Heart Failure Medications in Heart Function Clinics: the SHARE-HF Pragmatic, Stepped-wedge Trial

The goal of this clinical trial is to learn if a shared decision-making tool called SHARE-HF can help more people with heart failure receive guideline-recommended medications. The study includes adults with a type of heart failure called heart failure with reduced ejection fraction (HFrEF), who attend heart function clinics in British Columbia, Canada. The main question it aims to answer is: \- Does use of SHARE-HF during clinic visits lead to more participants receiving their recommended heart failure medications after 6 months? Researchers will compare clinics using the SHARE-HF tool to clinics providing usual care to see if the tool helps more participants get their recommended medications. Participants will use the SHARE-HF web-based tool with their clinician during regular clinic visits. The tool shows participants how their heart failure may affect their health over time, explains their medication options, and helps them and their clinician make treatment decisions together.

AI-Based Monitoring System for Chronic Heart Failure With Advanced Wearable and Mini-Invasive Devices

The goal of this observational, multicenter study is to evaluate whether AI-driven remote monitoring using a mini-invasive wearable device can improve clinical outcomes in adult patients (≥18 years) with chronic heart failure (CHF). The main questions it aims to answer are: * Can continuous remote monitoring reduce hospital admissions (emergency visits and hospitalizations) by 20% compared to standard care? * Does wearable-based remote monitoring improve functional, biochemical, and instrumental parameters in CHF patients? Researchers will compare patients using the wearable device (intervention group) to those receiving standard clinical follow-up (control group) to assess whether AI-driven monitoring leads to fewer hospitalizations, better disease management, and improved quality of life. Participants will: * Wear the EmbracePlus (Empatica Inc.) device continuously for six months (intervention group only). * Have their biometric data (SpO₂, HRV, EDA, respiratory rate, temperature, sleep quality) monitored remotely. * Receive automated alerts and teleconsultations if abnormal physiological changes are detected. * Attend scheduled follow-up visits (remote and in-person) for clinical evaluation and treatment adjustments. The study aims to provide real-world evidence on whether integrating wearable health technology with AI analytics can enhance CHF management and improve patient outcomes.

Endovascular Ablation of the Right Greater Splanchnic Nerve in Subjects With Reduced Ejection Fraction

This study is a small, early-stage clinical trial designed to test whether a new catheter-based procedure is safe and may help people with heart failure with reduced ejection fraction (HFrEF). The procedure uses the Satera Ablation System to treat the right greater splanchnic nerve, which may play a role in heart failure symptoms. The study also aims to identify which types of patients might benefit most from this treatment in the future. Up to 50 patients aged 40 or older with HFrEF will take part at as many as 10 hospitals worldwide. The study is prospective, meaning patients are followed forward in time, and it is randomized, double-blinded, and sham-controlled. Patients are randomly assigned in a 2:1 ratio to either receive the actual nerve ablation treatment or a sham (placebo) procedure. Randomization happens during the procedure, after anesthesia or sedation, to reduce the risk of revealing which treatment the patient receives. Neither the patient nor their heart failure doctor will know whether the patient received the real treatment or the sham. However, the doctor performing the procedure and certain study staff will know, mainly for safety and operational reasons. The sham procedure is designed to mimic the real procedure as closely as possible without performing the nerve ablation. It involves placing a small needle in the groin or neck and accessing the vein, but no treatment catheter is inserted. The sham procedure takes about the same amount of time as the real treatment (around 45 minutes) to help account for any placebo effect. Overall, this study is focused on evaluating safety and early signs of benefit rather than proving long-term effectiveness.

Precision Subtyping and Prognostic Study of Heart Failure Based on Multi-Omics Integration and Clinical Indicators: A Prospective Single-Center Cohort Study

This is a prospective single-center cohort study conducted at The First Affiliated Hospital of Xinjiang Medical University, aiming to enroll 400 patients with chronic heart failure (including HFrEF, HFmrEF, HFpEF) and 200 healthy controls.We will collect clinical data (e.g., NYHA class, NT-proBNP), multi-omics samples (genome, proteome, metabolome, gut microbiome), and imaging indicators (e.g., EAT density, myocardial strain) from participants at baseline. For patients treated with SGLT2 inhibitors, we will also track dynamic changes in multi-omics during follow-up.The main purpose is to build a composite risk prediction model (integrating multi-omics and clinical indicators) to predict the 1-year composite endpoint (heart failure rehospitalization or all-cause death). Secondary goals include identifying specific molecular profiles related to heart failure phenotypes, exploring the "gut-heart axis" mechanism, and finding early biomarkers for SGLT2 inhibitor response.All participants will be followed up for at least 12 months, and the study will strictly comply with ethical norms and protect the privacy of participants.
