Heart Failure NYHA Class IV

The goal of this clinical trial is to test the safety of lab-grown heart cells made from stem cells in subjects with congenital heart disease. The main questions it aims to answer are: * Is this product safe to deliver to humans * Is the conduct of this trial feasible Participants will be asked to: * Agree to testing and monitoring before and after product administration * Receive investigational product * Agree to lifelong follow-up Researchers will compare subjects from the same pool to see if there is a difference between treated and untreated subjects.

The aim of this mixed methods randomized controlled trial is to test the integrated nurse-led intervention bundle for family home care management of end-stage heart failure and palliative care in rural Appalachia. This intervention bundle is designed to address rural disparities in access to health care, with the help of the faith-based nurses and local volunteer visiting neighbors.

The Yale HF Registry is a live EHR based registry that allows for retrospective and real-time monitoring of Heart Failure case across the Yale New Haven Health System.

Introduction: Heart failure (HF) is a clinical syndrome that has advanced on a large scale concomitant with population aging and other factors. Thus, the search for alternatives that minimize the losses resulting from its structural and functional damage are important to optimize its treatments, with the primary objective of enabling the participation of these individuals in the most diverse daily tasks. Low-frequency (LF) or medium-frequency (MF) neuromuscular electrical stimulation (NMES) can be considered a resource to enable the improvement of vital and functional parameters of the population with HF intolerant to physical exercise, and it is also important to identify within these modalities which is most effective. In addition to these factors, kinesiophobia can be found in this population, and NMES can also be adopted as a strategy for kinesiophobia in these patients, with the objective of enabling the progression of behaviors. Objective: To evaluate and compare the effectiveness of LF and MF NMES on the indices of kinesiophobia and functionality in patients with HF. Methods: The research will be divided into two types of study: a double-blind randomized clinical trial (RCT) to evaluate NMES protocols, and a qualitative study with subsequent development and validation of a questionnaire to measure kinesiophobia in individuals with HF. The population included in the RCT will have their assessments (personal, socioeconomic, demographic data, Sit-to-Stand Test, kinesiological ultrasound and surface electromyography of the quadriceps muscles) conducted before their discharge from Hospital Nova Esperança (HNE), and after completion of the protocols at the same institution, in the city of João Pessoa - Paraíba. The application of NMES protocols will be carried out in the home environment (30 min/day, 3 times a week, for a total of 8 consecutive weeks). The population for the qualitative study and for the development of the questionnaire will consist of individuals diagnosed with HF of any etiology, compensated and able to perform kinesiotherapy activities, admitted to the HNE wards, between 24-48 hours before hospital discharge. An in-depth semi-structured interview will be conducted with these individuals, followed by the application of questionnaires developed based on the interviews, and the entire study will be conducted while the patients are hospitalized. Expected results: Regarding the first study, it is expected that patients treated with NMES will show improvements in clinical and functional variables, and these improvements may be more pronounced depending on the frequency applied. On the other hand, the qualitative study may reveal whether patients have fear of movement, even if they are clinically stable. The developed questionnaire will be well understood and have adequate psychometric qualities. Finally, it is expected that this knowledge can serve as a basis for optimizing the care of this patient population.

Introduction: Heart failure (HF), among cardiovascular diseases, is the disease that has been increasing its incidence and prevalence the most in recent years in the world population, due to the aging of the population. In addition, HF is the most frequent hospital diagnosis in the elderly, and is the main cause of hospitalization, with significant expenditure in public and private health care worldwide. Some functional tests have been used to predict the prognosis in patients with HF, however, the use of the 1-minute sit-to-stand test (SST1) to predict prognosis in HF has little scientific evidence, due to the lack of studies found in the literature for this population. Thus, the present study aims to evaluate the association between SST1 at discharge from the Cardio Intensive Care Unit (ICU) and the clinical outcome after 90 days in patients hospitalized for decompensated heart failure (DHF). Methods: This is a prospective cohort study analyzing the association between performance on the TSL1 and clinical outcome in patients hospitalized for DHF from June 2025 to October 2025. Sociodemographic, family, social, and clinical data will be collected from the participants, after which the TSL1 will be performed. The outcome of death and hospital readmission within 90 days after discharge from the ICU will be identified through telephone contact, which will be carried out by the researcher. Expected results: It is expected that from the results of this study it will be possible to understand whether performance on the TSL1 predicts clinical outcome for patients hospitalized for DHF and that it will even be possible to determine a cutoff point capable of predicting the outcomes of interest.

The Narrative Intervention for Chronic Illness-Heart Failure (NICI-HF) offers an asynchronous interactive text behavioral health intervention to advance behavioral health equity by facilitating access to care for people adjusting to living with heart failure (HF). The proposed study will recruit up to 70 people living with heart failure. This study will gain insight into living with heart failure and learn if the narrative-based intervention is feasible and acceptable for people living with heart failure. The study has two specific aims: Aim 1: Evaluate the effects of NICI-HF intervention on standard behavioral outcomes. The study investigators will review depression with the Personal Health Questionnaire-9 (primary) and anxiety with the General Anxiety Disorder-7 (secondary) outcomes, and explore self-care with the Self Care for Heart Failure Index by comparing the sham control (n=30) and NICI-HF intervention (n=30) groups at baseline, three months, and six months. Aim 2: Refine NICI-HF for feasibility and acceptability to support HF self-care and burdensome symptom management and to increase behavioral health equity by improving proximity to services. The study investigators will use standard implementation domains to tailor the intervention for HF using qualitative semi-structured interviews and mixed methods analysis. The study investigators will refine and manualize the intervention for future R01 testing across chronic illnesses with diverse and marginalized populations and service delivery models.

Ischemic heart disease (IHD) leads the global mortality statistics. Atherosclerotic plaques in coronary arteries hallmark IHD, drive hypoxia, and may rupture to result in myocardial infarction (MI) and death of contractile cardiac muscle, which is eventually replaced by a scar. Depending on the extent of the damage, dysbalanced cardiac workload often leads to emergence of heart failure (HF). The atrial appendages, enriched with active endocrine and paracrine cardiac cells, has been characterized to contain cells promising in stimulating cardiac regenerative healing. In this AAMS2 randomized controlled and double-blinded trial, the patient's own tissue from the right atrial appendage (RAA) is for therapy. A piece from the RAA can be safely harvested upon the set-up of the heart and lung machine at the beginning of coronary artery bypass (CABG) surgery. In the AAMS2 trial, a piece of the RAA tissue is processed and utilized as epicardially transplanted atrial appendage micrografts (AAMs) for CABG-support therapy. In our preclinical evaluation, epicardial AAMs transplantation after MI attenuated scarring and improved cardiac function. Proteomics suggested an AAMs-induced glycolytic metabolism, a process associated with an increased regenerative capacity of myocardium. Recently, the safety and feasibility of AAMs therapy was demonstrated in an open-label clinical study. Moreover, as this study suggested increased thickness of the viable myocardium in the scarred area, it also provided the first indication of therapeutic benefit. Based on randomization with estimated enrolment of a total of 50 patients with 1:1 group allocation ratio, the piece of RAA tissue is either perioperatively processed to AAMs or cryostored. The AAMs, embedded in a fibrin matrix gel, are placed on a collaged-based matrix sheet, which is then epicardially sutured in place at the end of CABG surgery. The location is determined by preoperative late gadolinium enhancement cardiac magnetic resonance imaging (LGE-CMRI) to pinpoint the ischemic scar. The controls receive the collagen-based patch, but without the AAMs. Study blood samples, transthoracic echocardiography (TTE), and LGE-CMRI are performed before and at 6-month follow-up after the surgery. The trial's primary endpoints focus on changes in cardiac fibrosis as evaluated by LGE-CMRI and circulating levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP). Secondary endpoints center on other efficacy parameters, as well as both safety and feasibility of the therapy.

The use of implantable left ventricular assist devices (LVAD) has increased over the last decade; partly because the newer continuous flow pumps feature a smaller design and better durability. These pumps have shown improved outcomes for those patients who don't qualify for heart transplantation and receive the LVAD device as a permanent therapy or a bridge to heart transplantation. Despite these improved outcomes, procedure related length of hospitalization for LVAD implantation is still 2 or 3 times that of other heart surgery treatments. One important reason for this is that many people experience right ventricular dysfunction after LVAD implantation. Treatment options for this are limited. Many LVAD patients with right ventricular dysfunction also have tricuspid valve regurgitation (TR). This is the failure of the tricuspid valve (TV) to close completely so that blood leaks backwards. Some recent studies suggest that correction of the TV during LVAD implantation has improved survival for those with severe regurgitation. However, this has not been evaluated for mild or moderate regurgitation. The goal of this study is to look at the clinical impact of surgical correction of mild to moderate TR in participants who are also undergoing LVAD implantation. The study will look at the degree of TR at various time points post-surgery, as well as any major cardiac adverse events, duration of hospitalization, and quality of life. The investigators hope to show that surgical correction of mild to moderate TR in LVAD patients will reduce right ventricular dysfunction and have a positive impact on health outcomes.
