This is a 22-subject prospective, multicenter, single-arm clinical trial to evaluate the safety and effectiveness of the Jarvik 2015 left ventricular assist device (LVAD) as a bridge to heart transplant in children weighing 8 to 30 kilograms. Data generated from the study will be used to support FDA review and potential approval of the device under the Humanitarian Device Exemption (HDE) regulation, the FDA approval pathway for devices intended to treat rare and orphan diseases.
This is a prospective cohort study, where we aim to investigate the effect of implementation of an electronic nudge alerting clinicians to the prescription of the 4 key pharmacological classes for the treatment of patients with heart failure and reduced ejection fraction (HFrEF) at the outpatient clinic in the Netherlands.
This a single-center, retrospective, observational study of patients that undergo coronary sinus(CS) lead revision, comparing epicardial lead placement to coronary sinus pacing(CSP) in those that had lead failure.
Heart failure is a syndrome that progresses with symptoms and signs caused by cardiac dysfunction and results in a shortened life expectancy (1). Acute heart failure resulting in hospitalization is a significant cause of morbidity and mortality. With the increase in the severity of the disease and rapid advances in the treatment of heart failure, these patients are frequently hospitalized and monitored in intensive care. (2) Five years after diagnosis, mortality can be up to 67%. Additionally, it is known that patients with heart failure are hospitalized on average once a year after diagnosis. (3) In a multicenter study, it constituted 14% of 3000 cardiac patients admitted to intensive care units. Additionally, due to longer ICU stays, these patients accounted for 33% of total inpatient days. An increasing number of heart failure patients require intensive care due to respiratory failure, regardless of left ventricular ejection fraction. Heart failure accounts for approximately one-third of patient days in intensive care units, and this burden is increasing. This shows that attention should be paid to the quality of care for patients requiring critical care. (2) Multidisciplinary programs have been implemented to deal with the high prevalence. However, the optimal follow-up frequency is unknown. Therefore, some tools are needed to improve patient prognosis (3). Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker whose values in both urine and plasma have been associated with acute kidney injury (AKI). Although NGAL is an early specific biomarker for AKI, it has not yet come into routine use, but is frequently used in clinical and experimental studies (4). Venous load ultrasonography score (VExUS) is a new systemic congestion scoring method based on inferior vena cava dilation and pulsed wave Doppler (PW-Doppler) morphology of the hepatic, portal and renal veins. It has been proposed as a score to assess systemic congestion.
The study team is studying how increasing dietary fiber, specifically through adding potato starch to participant's diet, may impact the species of bacteria in participant's gut microbiome. The study team also wants to understand if adding potato starch to participant's diet helps these bacteria make more short chain fatty acids, a byproduct the team thinks may benefit participant's health.
Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.
The objective of our research is to evaluate the effectiveness of an innovative medical device designed to measure foot and lower leg sizes in detecting early indications of deteriorating heart failure. This health condition frequently causes leg swelling and breathing difficulties due to fluid accumulation. Early detection of these symptoms is vital for effective management, potentially preventing the need for hospitalization. Fluid retention in the lower legs and lungs, manifesting as swollen ankles and shortness of breath, is a common sign of progressing heart failure. Often, a slight increase in body weight is the first warning of fluid accumulation, occurring before noticeable swelling or breathing issues arise. Early identification of these fluid accumulation signs is critical for timely intervention, which can avert the necessity for hospital admittance. Patients are usually encouraged to monitor their weight, check for swelling in the ankles, observe their breathing, and consult with their healthcare provider or heart failure specialist at the first sign of these symptoms. In many cases, patients can report these symptoms in time for their healthcare team to adjust their treatment accordingly. Diuretics, or water pills, are often prescribed to help eliminate excess fluid, effectively preventing hospital admissions when used promptly. The Heartfelt device may provide a useful solution for individuals who find it challenging to consistently monitor these indicators and their weight. It is designed to detect early warning signs seamlessly without imposing additional tasks on the patient's daily routine. The device, intended to complement rather than replace self-monitoring practices, is user-friendly and operates by scanning the feet for any size changes, positioned conveniently by the bedroom floor. This capability allows healthcare professionals to make informed decisions swiftly about patient care, potentially adjusting treatments to avoid further health complications. The device captures images of the feet only, ensuring privacy. This study aims to ascertain the device's practical effectiveness in real-world scenarios, aiming to collect precise data to confirm its potential benefits for patients facing heart failure challenges.
A clinical trial of exercise-similar heart rate acceleration delivered via cardiac pacing vs. sham intervention in subjects at rest will be performed. The study population comprises subjects with guideline-directed medically managed severe left ventricular dysfunction due to ischemic or non-ischemic cardiomyopathy and an existing implantable cardioverter defibrillator or biventricular implantable cardioverter defibrillator. The purpose of the study is to understand how the heart rate pattern of exercise contributes to the considerable cardiac conditioning effects of exercise and estimate whether the pacing approach may have translational clinical applicability. Fifty-two subjects will be randomized, single-blinded, to either the pacing intervention or a sham intervention which they will receive once daily, 3 days/week for 6 weeks. Baseline symptoms and clinical test results will be compared to the same measures at 2 weeks, 4 weeks and 6 weeks of intervention/sham and at 3 months and one-year post-intervention. The primary endpoint will be the change in left ventricular ejection fraction from baseline in intervention vs. sham groups (mixed effects linear regression with time and treatment arm as fixed effects and pre-specified covariates of sex and cardiomyopathy type as random effects). Secondary endpoints will include changes in quality of life, 6-minute walk distance, cardiopulmonary exercise test (CPET) measures, daily activity and major adverse cardiac events (MACE) at 3 and 12 months between pacing and sham groups. A "dose-response" analysis of outcomes at 2, 4, and 6 weeks of the intervention vs. sham compared with baseline will be performed.
Heart failure (HF) patients often develop pulmonary hypertension (PH) that leads to transition into a biventricular HF with poor prognosis. There are two PH components: 1) passive transmission of increased left atrial pressure, 2) heart failure (HF) related pulmonary vascular dysfunction (PVD) with increased vascular resistance. Intriguingly, only some, but not all HF patients develop heart failure-related PVD. The mechanisms and non-invasive detection of HF-PVD are poorly understood and are the focus of the current grant application. Development of PVD is linked to insufficiently characterized metabolic factors that may be mediators of HF-PVD. Untargeted metabolomics is an emerging powerful platform for the discovery of pathways linked to diseases. Its specificity can be further enhanced using transpulmonary gradient sampling. Part A of the project aims to identify novel metabolites associated with the presence of PVD in patients with HF that can serve as biomarkers or targets and will provide biologic insights into PVD. Part C will assess the effects of reverting of metabolic alterations (identified in part A) by a drug/diet on pulmonary vasculature in experimental HF-related PVD. The "gold standard" for the detection of PVD is right heart catheterization, which is invasive and risky. Heart failure-related PVD is therefore often diagnosed late. There is a need for noninvasive tests that may help to detect PVD in early stages and can be done repeatedly. Recent advances in artificial intelligence (AI)-assisted automated quantitative analysis of lung texture from low-dose contrast-free high-resolution CT images allow to quantify lung water content, interstitial changes or vessel volume, and may provide clues for detection of heart failure-related PVD. Such an approach, not tested yet, will be utilized for the detection of HF-PVD (part B). Clinical and functional characteristics of lung circulation (exercise hemodynamics, diffusion capacity, perfusion) will be analyzed in relation to quantitative CT data.
