Active clinical trials for "Heart Failure"

Sleep disordered breathing, in which patients my breath deeply, shallowly or stop breathing for periods whilst asleep, is common in heart failure and associated with a poor prognosis. This study aims to validate a novel function available on certain pacemakers which is designed to detect this condition.The investigators hypothesize that ApneaScan can accurately detect moderate to severe sleep disordered breathing in patients with heart failure as compared against an Embletta sleep study. The investigators will also follow up our patients for 2 years to determine whether the severity of sleep disordered breathing as assessed by ApneaScan correlates with prognosis.

The purpose of this study is to explore the experience in being with advanced Heart failure patients.

A prospective observational multi-centre study for the validation of the ApneaScan algorithm (integrated in ICD devices (with or without cardiac resynchronization therapy function) of the "Incepta" series for the screening of sleep disordered breathing in patients with stable symptomatic chronic heart failure, using portable polygraphy monitoring device ("Embletta Gold") as reference for the Apnea-Hypopnea-Index (AHI). Secondary objectives are the detection of severe sleep disordered breathing in patients with clinically indicated in-laboratory polysomnography, as well as correlations of the AHI detected by ApneaScan with other clinical endpoints like mortality, hospitalization, atrial fibrillation and ventricular arrhythmia.

Dyspnea (breathlessness) on exertion is the most prevalent and distressing symptom of heart failure (HF). Nevertheless, the mechanisms of dyspnea in HF remain poorly understood. Thus, the general aim of this pilot study is to advance our understanding of the mechanisms of activity-related dyspnea in patients with HF. Studies will be performed in patients with mild, moderate and severe HF (n=24) as well as in healthy, age- and sex-matched control subjects (n=8). We will test the hypothesis that the increased prevalence and severity of activity-related dyspnea in HF reflects the interaction between an exaggerated drive to breathe and the inability of the respiratory system to meet this increased demand. Detailed physiological and perceptual responses to bicycle exercise will be examined and compared, first, between HF patients and healthy control subjects and, second, across patients with varying degrees of HF severity. The results from this preliminary study will be used to help design future studies in this patient population.

The purpose of this study is to determine whether oscillatory pattern of sympathetic nerve activity muscle is an efficient index for the prognosis of patients with heart failure.

The purpose of this study is to develop a biobank containing samples of 2,000 patients treated in a tertiary cardiology hospital containing electronic medical records and genetic data in genome-wide scale for performing genetic association studies for validation and development of medical decision routines that help the clinical management of heart failure patients.

Treatment of chronic heart failure requires multidisciplinary approaches with a recognized role for cardiac rehabilitation. Rehabilitation helps to improve patient's functional, decrease morbidity and mortality, decrease rehospitalization rate, thereby reducing costs of this disease. After recovery from the acute phase of cardiac infarction, patients admitted to the rehabilitation center will follow the usual rehabilitation program during the hospitalization period. This step precludes outpatient follow-up period in our day hospital, in accordance with their physicians and cardiologists who manage the monitoring. The study INCARD (Insuffisance Cardiaque en Readaptation Durable) will be developed to evaluate the benefits of a sustainable rehabilitation heart failure on patients treated optimally and educated during a follow-up period of 24 months. The main objective of the study will be to compare the benefits of rehabilitation between coronary (C) and non-coronary (NC) patients for each evaluation time point, periodically recorded

Heart failure (HF) is a serious and challenging syndrome. Globally 26 million people are living with this chronic disease and the prevalence is still increasing. Besides this growing number in prevalence, HF is also responsible for almost 1 million hospitalizations a year in the US and in Europe. Consequently, this has a major economic impact especially due to recurrent admissions of these patients. Adequate prediction of decompensation could prevent (un)necessary admissions as a result of heart failure. Philips is developing a Bayesian Hemodynamics model for general practitioners. This model uses different observables, which can be measured at home. The outcome of the model could be used as an aid in clinical decision making in HF patients.

Screening Of adult urBan pOpulation To diAgnose Heart Failure (SOBOTA-HF) is a cross-sectional prevalence study in a representative sample of Murska Sobota residents aged 55 years or more. Individuals will be invited to participate in a screening with NT-proBNP. All subjects with NT-proBNP ≥ 125 pg/mL will be invited for a diagnostic visit that will include history and physical examination, electrocardiogram, echocardiography, ankle brachial index, pulmonary function tests, body composition measurement, physical performance tests and questionnaires. To validate the screening procedure, a control group (NT-proBNP < 125 pg/mL) will undergo same diagnostic evaluation. An external center will validate echodardiography exams and the HF diagnosis will be adjudicated within an independent HF expert panel. Overall and age specific HF prevalence will be calculated in individuals ≥ 55 years and extrapolated to the whole population.

Myocarditis promotes the occurrence of serious cardiac arrhythmias and conduction disorders which may lead to sudden cardiac death, the need for catheter ablation of arrhythmia or implantation of a cardioverter-defibrillator or pacemaker. The aim of the study is to fill the evidence gap regarding the type and burden of arrhythmias in patients with myocarditis and their correlation with clinical parameters, biomarkers and additional tests. During a multi-center observational study, patients will be subjected to prolonged ECG monitoring. As a result, a risk scale will be created that can facilitate the identification of patients with an increased risk of arrhythmia and further specifying recommendations for therapeutic management.
