Active clinical trials for "Heart Failure"

KorHF III is a multi-center, nationwide, prospective registry of the Korean Society of Heart Failure, which enrolls patients with acute heart failure in Korea. The aim of this registry is to analyze the etiology, treatment, treatment, and prognosis to develop strategies for managing acute heart failure.

The evolving definitions of HF, the increasing attention of the medical community, and the aging of the population are some of the factors contributing to a still debated incidence and prevalence of HFpEF across the general and specific populations. Despite the current decline in new HF cases, HFpEF shows stable incidence according to epidemiological studies. Cardiovascular risk factors, such as a long history of hypertension, diabetes, obesity, and others seem to be associated with a higher HFpEFincidence. Nevertheless, the potential echocardiographic predictors of HFpEF have not been defined yet. Hypothesis In a population at high risk for HFpEF, collected using a multicenter echo-lab network, the real incidence of HFpEF cases and echocardiographic predictors can be identified. Aim 1: to define the incidence of HFpEF in a high-risk cohort of patients afferent to the Italian echo-lab network. Aim 2: to explore the standard (2D and Doppler data) and advanced (LV and LA strain) echocardiographic parameters associated with and potential predictors of HFpEF. Methods This is a multicenter, prospective, observational study involving an Italian echo labs network. According to inclusion and exclusion criteria, patients will be enrolled during standard echocardiographic evaluation. After signing informed consent, clinical and echocardiographic data will be collected. Thereafter, they will be followed up for major clinical events (cardiovascular death, HF requiring hospitalization, myocardial infarct, and atrial fibrillation) for a period of 12 months

This study seeks to investigate the clinical value of novel echocardiographic indices, including myocardial work parameters, during the acute phase of heart failure hospitalization. The trajectory of novel echocardiographic indices from the start to the end of hospitalization will be captured, as a means to unravel and subsequently better understand the diverse pathophysiology of different phenotypes of the heart failure continuum. Correlation between novel echocardiographic indices with clinical data, biochemical data, different heart failure phenotypes, and therapeutic maneuvers will be attempted. Prognostic implications of those indices will be explored.

The goal of this observational study is to learn about heart function and high lung blood pressure in patients with heart failure. The main question[s] it aims to answer are whether we can improve the ability to predict patients who will have complications after they receive treatment including heart transplant and left ventricular assist devices.

The goal of this observational study is to learn about left atrial reservoir strain in patients with heart failure with preserved ejection fraction. The main questions it aims to answer are: Usefullness of LARS as a predictor of high HFA-PEFF diagnostic algorithm scores (≥5) The relative importance of LARS in variables including each component of HFA-PEFF and traditional cardiovascular risk factors.

Heart failure (HF) with a left ventricular ejection fraction (LVEF) >0.40 is a large medical problem, for which no drug or device has a recommendation in current HF guidelines. The prevalence of mortality and HF hospitalizations in HF with LVEF >0.40 is high, but the identification of predictors for increased risk of mortality and HF hospitalizations in this patient category remains difficult. The hypothesis of this study is that the risk of all-cause mortality and HF hospitalizations can be measured by clinical factors, imaging parameters and circulating biomarkers, and that these factors can be used in a risk profile

Heart failure with preserved ejection fraction (HFpEF), a certain type of heart failure, occurs when the heart doesn't pump blood around the body properly. It can cause breathlessness, tiredness, and swollen feet or ankles. It is not clear why people develop HFpEF and treatment options are very limited. TRAITS-HFpEF is a study that aims to understand why people develop HFpEF, identify new tests and treatments, and gain information on the life expectancy of people living with this condition. It will do this by routinely collecting information on people attending a specialised outpatient HFpEF clinic.

In a prospective, observational pilot study of patients scheduled for an atrial fibrillation (AF) ablation at the University of Vermont Medical Center the investigators will compare exercise capacity before and four months after AF ablation.

This prospective observational research will be conducted to assess the burden of hyperkalemia including treatment and disease burden of patients in a long-term continuous care from various aspects including adherence to the medication for hyperkalemia and HR-QoLs.

Hypothesis: Tissue and serum samples collected from end-stage heart failure patients receiving left ventricular assist device implantation (LVAD) or heart transplantation will provide information regarding the basic science of heart disease. Tissue and serum samples collected from a limited numbers of "healthy controls" (donor grafts that were not utilized for heart transplantation) will serve as a comparator in research database projects. Design: This is a registry project; there are no investigational treatments, drug or procedures associated with participation in registry activities. This project is an organized functional data and tissue data gathering and storing (database) endeavor with specific focus on the functional, structural, and molecular aspects of heart failure. Data collection will not immediately influence the course of treatment for any patient.
