Active clinical trials for "Heart Failure"

The primary objective of this study is to evaluate the feasibility of a novel app to facilitate heart failure patients to acquire lung ultrasound images and evaluate the quality of those images to expert scans, and to evaluate for relationships between the ultrasound data and pulmonary pressure data from the Abbott CardioMEMS system.

Heart failure (HF) affects about 1% of patients younger than 55 years, whereas the prevalence of HF increases > 10% in patients with at least 70 years of age. Despite HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF), the clinical significance of HF with mildly reduced ejection fraction (HFmrEF) has gained more importance within the past years. Those patients are characterized by a left ventricular ejection fraction (LVEF) of 41-49%. However, within the current European guidelines, limited treatment recommendations in this subgroup of HF are yet available as a consequence of the limited number of studies in this field. The "Heart Failure With Mildly Reduced Ejection Fraction Registry" aims to characterize patients with HFmrEF and investigated the prognostic impact of interventional and pharmacological therapies in this subgroup of HF patients.

In this study, the hypothesis being explored is that VO2Max and other CPET parameters can be accurately estimated from biosignals (namely, motion from accelerometers and cardiopulmonary variables from EKG) collected during activities of daily living using wearable biosensors worn by study participants. This study will aim to collect development and validation data for a machine learning algorithm and to evaluate the performance of the algorithm. A total of 300 participants will be enrolled including: (Normal) 200 participants, self-reported healthy male and female participants aged 18 to 80 and (Standard of Care) 100 participants

The goal of this study is to test the impact of a virtual heart failure optimization program on uptake of guideline directed medical therapy, participation in cardiac rehabilitation & impact on echocardiographic parameters.

Sensorum Health (Sensorum) is conducting a pilot study to determine if Sensorum's proprietary passive sensor network can be used to identify signals of early health decompensation in subjects prior to a hospitalization for chronic disease exacerbation or other ambulatory care sensitive conditions. Successful early detection would provide a window of opportunity to intervene outside of the acute setting in future interventional studies.

The goal of this observational study is to learn about the influencing factors of chronic heart failure prognosis in heart failure patients. The main question it aims to answer is that what are the influencing factors of clinical outcomes in chronic heart failure. Participants will be collected multiple omics data such as phenotype group, environmental exposure group, intestinal microbiome, genome, metabolome, and noninvasive biomarkers.

Heart failure (HF) is a common disease, which impacts on other organs. Despite an ongoing progress in knowledge about HF, there are still some uncharted aspects of impact of HF on respiratory system. The aim of the study is to determine whether there are any differences in pulmonary changes assessed in chest CT, chest ultrasound or in pulmonary function tests between patients with HF with decreased (≤40%; HFrEF) and preserved (≥50%; HFpEF) ejection fraction. Eighty four patients diagnosed with HF will be included (42 with HFrEF and 42 with HFpEF) and the following tests will be performed : echocardiography chest X-ray and CT assessment of lung hydration in ultrasound spirometry, plethysmography, diffusion capacity for carbon monoxide (DLCO) arterial blood gas analysis peripheral blood collection In patients with abnormal, suspected changes in the lungs diagnosed in the chest CT bronchoscopy and endobronchial ultrasound (EBUS) will be offered. The primary outcome will be difference in frequency of chest CT abnormalities (ground-glass opacities or interlobular septal thickening or pleural effusion or mediastinal lymphadenopathy) between patients with HFrEF and HFpEF The secondary outcomes will be: difference in pulmonary function test results (FEV1, FVC, TLC, RV, DLCO) differences in arterial pO2 and pCO2 differences in B- line scores in ultrasound differences in concentration of blood biomarkers (troponin, CRP, NTproBNP, IL-6, TNF-α, sST2, Gal-3, GDF-15) The results of the study will allow to .better understand the pathomechanisms of the occurrence of lesions in lungs secondary to HF. Thus, it may anable to reduce unnecessary diagnostics in patients with HF in the future.

Despite improvements in therapy, heart failure is a disease with high mortality and accelerating prevalence. To improve patient care, it is necessary to better understand the features and underlying mechanisms of myocardial remodeling; how it manifests in vivo and its underlying cellular and extracellular changes. The RELAX study will offer insight into myocardial remodeling, by comprehensively assessing function and structure of failing human hearts, and investigate its underlying cellular and extracellular changes.

The purpose of this study is to test a clinical decision support (CDS) tool that provides clinicians (cardiologists and nurse practitioners) medication recommendations regarding guideline directed medical therapy (GDMT) in patients with heart failure and reduced ejection fraction (HFrEF).

Levosimendan, a drug with inotropic, vasodilatory and myocardial protective properties, has been proposed for the prevention and treatment of postoperative low cardiac output syndrome in cardiac surgery. Despite preliminary studies with promising results, large randomized controlled trials aimed at demonstrating the benefits of levosimendan did not show superiority over placebo in this indication. However, in these studies, the infusion was neither performed at the maximum dosage nor during the 24 hours preceding the surgery, but mainly at the very beginning of the operation. However, post hoc analyses showed a reduction in mortality and in the occurrence of low cardiac output syndrome in the subgroup of patients who had undergone isolated coronary artery bypass grafting, in contrast to those who had undergone valvular or combined surgery. Another recent study suggests that under similar conditions, preconditioning with levosimendan started 48 hours before surgery reduces the length of stay in intensive care and the average cost of hospitalization. There are no formal recommendations on the prophylactic use of levosimendan in cardiac surgery for heart failure patients with impaired LVAS. However, the France-Levo registry, a multicenter observational study requested by the HAS, has shown that in real practice there is a place for preconditioning with levosimendan, which is used in this indication for 7% of the patients in the registry. The Cardiovascular Surgery and Transplantation Department of the Nancy Brabois University Hospital, which actively participated in the France-Levo registry, is one of the cardiac surgery centers that uses this practice, as is the University Hospital of Rouen. It is interesting to be able to evaluate retrospectively whether levosimendan preconditioning has a positive impact on the postoperative prognosis of patients and more particularly on the reduction of the length of stay in critical care and in hospital compared to standard management.
