Active clinical trials for "Heart Failure"

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

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 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.

Potentially Avoidable Hospitalizations (Pah) Are Studied As An Indirect Measure Of Access To Primary Care And Of The Interface Between Primary And Secondary Care. A Previous Work Unveils Considerable Geographic Variation In The Rate Of Pah In France And Suggest That Primary Care Organization Might Play A Role In This Variation. However, A Limitation Of This Work Lies In The Lack Of Data On Actual Primary Care Utilization. The Aim Of This Study Is To Analyze The Role Of Primary Care In The Variation Of Potentially Avoidable Hospitalizations At the Zip Code Level, In The French Region Languedoc-Roussillon-Midi-Pyrénées. The investigator will implement An Ecological Approach In Which The Geographic Variation In The Rate Of Pah Is Analyzed In The French Region Lrmp, Year 2014. Age- And Sex-Adjusted Rate Of Pah By Zip Codes (N=612) Is Modeled Using A Spatial Regression Model.

This is a study to determine if two ultrasound measures (Corrected Flow Time and B-Lines) can predict patients at higher risk of readmission within 30 days of hospital discharge for decompensated heart failure.

Determination of risk factors of ventricular arrhythmias (VAs) after implantation of continuous flow left ventricular assist device in order to characterize which patient requires ICD implantation in primary prevention.

Comparison of changes in diastolic pulmonary artery pressure as measured by CardioMEMS™ to impedance parameters as measured by ImpediMed's BIS technology.

The main objective was to assess the prevalence of sarcopenia in chronic heart failure patients and in patients before the trans aortic valvular implantation. The loss of muscle mass in chronic heart failure patients is a prognostic factor for sarcopenia. The purpose was to identify in these patients signs of sarcopenia for a better management.

This is a prospective cohort to describe clinical characteristics, predictors of poor outcomes both during hospitalization and at home, functional status, and quality of life among patients aged 13 years or more, consecutively admitted with acute decompensated heart failure at Mbarara Regional Referral Hospital.
