Active clinical trials for "Heart Failure"

This randomized controlled trial compares a home telemonitoring system (HTS) versus usual care during a 90 days follow-up of Heart Failure (HF) ambulatory patients, in order to evaluate if the use of the HTS improves self-care and treatment adherence. The study was reviewed and approved by the Methodological Committee and by the Research Ethics Committee from the Provincial Health System, according to the Declaration of Helsinki. Written informed consent was obtained before randomization.

Comorbid chronic lung disease (CLD) increases mortality in heart failure (HF) patients. Understanding the predictors and pathophysiology of HF can improve the efficacy of HF treatment. This study evaluated the cardiopulmonary exercise test (CPET) results to identify significant predictors on long-term outcomes in HF patients with CLD.

It's the aim of this study to analyse efficacy and reliability of VectSelect Feature for avoidance of phrenic nerve stimulation in cardiac resynchronisation therapy (CRT) patients.

The purpose of this study is to determine whether hair cortisol and testosterone levels correlate with heart failure status in patient with chronic congestive heart failure.

Early morning weights to monitor CHF patient's fluid status is common practice but there is a lack of evidence that this is the best practice. The purpose of this study is to determine if there is a difference in net weight gain or loss for hospitalized patients with CHF who are weighed in the evening instead of early morning.

The aim of the study is to assess the cardiac innervation in patients with heart failure to better select candidates for an implantable cardioverter defibrillator. Cardiac innervation will be assessed using an imaging agent administered intravenously.

Background: - Heart failure is a common cardiovascular disorder whose incidence increases with age, affecting up to 10% of people older than 65 years of age. As the population ages, the prevalence and cost of heart failure will continue to rise. Researchers are interested in using noninvasive imaging methods to better understand the symptoms and effects of heart failure. Objectives: - To conduct a noninvasive comparative imaging study of individuals with heart failure. Eligibility: - Individuals at least 18 years of age who have been diagnosed with heart failure (with at least mild symptoms and slight limitations on physical activity). Design: This study will last approximately 2 years and will require four visits to the National Institutes of Health Clinical Center, with one screening visit and three study visits. Participants will be screened with a full medical history and physical examination, as well as blood and urine samples. Participants will have the following tests during each study visit: Physical examination Blood and urine samples Cardiac magnetic resonance imaging Cardiac computerized tomography to study the blood vessels in and leading to the heart Echocardiogram to evaluate heart function Electrocardiogram to measure heart electrical activity The three study visits will take place 1 year apart. Participants will also receive follow-up phone calls 6 months after the first and second visits. No treatment will be provided as part of this protocol.

Prevention of myocardial functional deterioration and sudden cardiac death among individuals of intermediate risk remains one of the most elusive frontiers of contemporary medicine. While most of these individuals are known to have had contact with the medical system, they are frequently not considered to be at high risk until far advanced along one or multiple disease processes leading to irreversible myocardial loss and electric instability. The goal of this proposal is to determine the prognostic power of combining specific measures of ventricular architecture, myocardial structure and electrical function for the early identification of individuals at risk to develop ventricular arrhythmias and progressive myocardial failure leading to severe cardiovascular outcomes and death.

The aim of this study is to establish a model for the evaluation of drug targets using postural measures to induce changes in lung water concentration as assessed by MRI. A reduction in the magnitude and rate of water transudation with postural changes in patients with congestive heart failure (CHF) could provide a model for the evaluation of various classes of molecules for target validation and for dose selection.

The purpose of this study is to evaluate and compare the effectiveness of the HeartMate II (HM II) Left Ventricular Assist Device (LVAD) support versus OMM in ambulatory NYHA Class IIIB/IV heart failure patients who are not dependent on intravenous inotropic support and who meet the FDA approved indications for HM II LVAD destination therapy.
