Active clinical trials for "Heart Failure"

Heart failure and atrial fibrillation (AF) often coexist, and each increases the morbidity and mortality associated with the other. The investigators hypothesized that restoration of normal sinus rhythm by catheter ablation is superior to medical treatment of AF in heart failure. This study randomizes patients with heart failure and persistent AF to medical treatment of AF or catheter ablation to restore sinus rhythm.

This is a prospective study that aims to define the utility of cardiac magnetic resonance feature tracking (CMR-FT) as a non-invasive quantification tool to assess diastolic functionality in patients with Heart Failure with preserved ejection fraction.

This protocol is a prospective pilot study utilizing the intervention of a medically supervised, registered nurse and registered diabetes educator coached low-carbohydrate, ketogenic diet to examine the impact it has as a treatment for heart failure with preserved ejection fraction.

Heart failure impairs quality of life and exercise capacity, despite an optimal medical therapy. Alternative methods, like hypoxic conditioning coupled to exercise training, must be explored and describe

The study is aimed to evaluate if the education of the caregiver is able to reduce hospital admissions of patients with heart failure assisted at home.

The ADAPTION trial is an investigator initiated prospective randomized doubleblind cross-over pilot study in a multi-center setting. Aim: to assess the ability of minute ventilation (MV) sensor driven rate adaptive atrial stimulation to restore functional capacity and quality of life in heart failure patients with chronotropic incompetence. Methods: heart failure patients (left ventricular ejection fraction ≤35% & New York Heart Assessment II or III) who were implanted with a 2-chamber implantable cardioverter defibrillator (ICD) device equipped with a MV sensor that are diagnosed with chronotropic incompetence will be included in the study. Patients will be randomized in a 1:1 fashion to rate responsive pacing (MV sensor only) function ON (AAIR mode) or OFF (DDI mode). After 3 months the pacing mode will be switched to the opposite mode.

The study aims to explore two marketed devices providing a multimarker monitoring including physical activity under real-life conditions in patients with heart failure with preserved ejection fraction (HFpEF) and with heart failure and reduced ejection fraction (HFrEF). It aims to identify potential novel endpoints for future heart failure trials by exploring clinically relevant changes over time and correlations/associations with conventional endpoints such as the six minute walking distance (6MWD), biomarkers and clinical events. Furthermore, it aims to address the challenges and feasibility of implementing device based measurements under real-life conditions.

To determine whether an integrated AI decision support can save time and improve accuracy of assessment of echocardiograms, the investigators are conducting a blinded, randomized controlled study of AI guided measurements of left ventricular ejection fraction compared to sonographer measurements in preliminary readings of echocardiograms.

The main objective is to replicate the validation of omics biomarkers of left ventricular diastolic dysfunction in patients with metabolic syndrome. The aim was to recruit overall 750 patients in Europe (100 for France). Currently, 625 patients were enrolled in Europe and 47 in France.

Study hypothesis is that the time from randomization to the increase of natriuresis (%), time to standardization of natriuresis daily profile, blood pressure profile and the percentage reduction of central hemodynamic parameters will be relatively changed over the study period by more than 15%.
