Active clinical trials for "Heart Failure"

Invasive pulmonary capillary wedge pressure measurements using a Swan-Ganz catheter (SGC) is considered the gold standard for cardiac output (CO) monitoring. In this prospective study, we will compare CO measurements between a PPG-based wearable monitor and a SGC in ambulatory CHF patients.

The study has been carried out to determine diagnostic and therapeutic pathways in a group of HF diabetic patients and to verify whether the use of innovative antidiabetic therapies could modify echocardiographic parameters and influence cardiological therapy.

The aim of this prospective cohort study is to assess the adherenсe to medical therapy and its influence on long-term outcomes in patients with chronic heart failure in the outpatient registry

Assessment of the prognostic value of the estimation of plasma volume or its variation in patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) after acute right heart failure.

The study includes two parts: Part 1: 100 examinations of patient referred for echo evaluation, containing clips that were acquired from the 4CH apical view were collected retrospectively. Each study includes 10 clips that represent typical user scanning errors Offline evaluation of the system (by batch processing) shall be performed by comparing the system output to preliminary quality tagging by experienced sonographers Part 2: Live scans of apical 4CH clips of patients with indication for POCUS examination will be performed by POC physicians LVivo IQS shall be used (on Lumify) during the scan for patients that meet inclusion criteria until 50 exams will be collected. 3 sec of each scan shall be saved, and Image quality score (IQS) shall be documented Saved scans shall be reviewed by an expert physician to determine whether they are clinically interpretable

This study evaluated changes in healthcare resource utilization (HCRU) and costs of care within 12 months following initiation of sacubitril/valsartan (sac/val) in commercially insured and Medicare Advantage (MA) lives in the U.S among adult patients with heart failure with reduced ejection fraction (HFrEF) (cohort 1) and adult patients with chronic heart failure (CHF) (cohort 2).

The aim of this study was to design a deep learning-based trained model to assist in HFimpEF diagnosis.

This is a bi-centric, prospective randomized study to evaluate the contribution of rapid echocardioscopy at the patient's bedside to improving the prognosis of patients hospitalized for acute heart failure. The following markers will be evaluated: sST2, Copeptin, chromogranin, NGAL, suPAR and cystatin.

The diagnosis of heart failure with preserved ejection fraction has so far been made primarily according to criteria determined by echocardiography, or invasively by measuring the left ventricular filling pressures. Increasingly, CMR is also evaluated with regard to the diagnosis of cardiac insufficiency with preserved pump function.However, it is still unclear which parameters can be used meaningfully for diagnostics.To answer this question, the investigators want to retrospectively evaluate data collected from patients with a clinical indication for CMR and coronary angiography.

LEDA (Lithuanian Echocardiography study of Dyspnea in Acute settings) is a prospective observational cohort multicenter clinical study. Project is carried out by Vilnius University together with a partner Lithuanian University of Health Sciences, in conjunction with a research protocol of international GREAT consortium (Global Research on Acute Conditions Team). The aim of this project is to find the specific novel biomarkers of acute heart failure (AHF), to evaluate their diagnostic and prognostic role in association with echocardiographic parameters of AHF. Primary endpoint is 1-year all-cause mortality and rehospitalization. Secondary endpoints are 1) in-hospital all-cause mortality 2) post-discharge 1 and 3 month all-cause mortality and rehospitalization 3) post-discharge 1 and 3 month cardiovascular mortality and rehospitalization 4) one-year cardiovascular mortality and rehospitalization. During the project a sizeable national database (2000 Lithuanian patients) will be integrated into database of GREAT network. Novel cardiac biomarkers together with ultrasound parameters of right ventricular (RV) function are in the focus of the study. During the acute phase of heart failure, up to 15 novel cardiac, vascular, renal impairment and inflammation biomarkers in plasma samples will be investigated in Lithuania and France (INSERM laboratory). Plasma samples will be taken during 4 hours after admission and frozen at -80ºC to allow batch analysis. The extensive evaluation of innovative ultrasound parameters of right ventricular structure and function will be performed in the early hospitalization period, along with standard echocardiography examination. The first database of AHF patients in Lithuania will provide demographic data and trends of morbidity and mortality, as well as analysis of diagnostic and prognostic value of novel biomarkers and echocardiography parameters in the Baltic region. Quantitative parameters of RV systolic function and deformation will be measured. It is expected that optimal use of novel biomarkers and reproducible echocardiography parameters in the setting of emergency and critical care would reduce unnecessary hospitalizations, cost and hospital length of stay without decrease in the quality of diagnostics and treatment. An estimation of correlation of echocardiographic parameters and biomarkers could help create an accurate algorithm for risk stratification and diagnosis of AHF in an emergency setting.
