Active clinical trials for "Heart Failure"

This study will use contrast echocardiography to assess the accuracy of a new non-invasive imaging method for subharmonic aided pressure estimation (SHAPE) compared to simultaneously acquired intra-cardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.

Heart failure (HF) is a severe disease, burdened with a poor prognosis (30% mortality at 2 years, 30% of rehospitalization within 1 month). It is also a major cause of health burden representing between 1.5 and 2 billions euros per year in France. Approximately 75% of these costs are due to hospitalization. Besides physical examination and echocardiography, biology may help refine the diagnosis, but also could provide powerful prognostic parameters. This study aims to assess the value of ST2 in the management of patients admitted for HF to reduce readmission at one month.

The objective of this study is to investigate whether nutritional supplementation with magnesium can improve cardiovascular structure and function in participants with obesity - with a long-term goal of preventing clinical heart failure. Specifically, in a randomized open-label pilot study, we will assess whether dietary Magnesium (Mg) supplementation (versus no supplementation) for 24 weeks in obese patients will improve left ventricular (LV) mass.

In this trial the measurement of whole body water will be compared to the standard method of measuring the body weight as treatment guidance in patients with decompensated heart failure. The Seca mBCA 515 [medical Body Composition Analyser] will be used to quantify the whole body water by using bioelectrical impedance analysis.

This study is a multicenter, prospective, randomized cross-over study to compare His Bundle Pacing (HBP) with Bi-Ventricular Pacing (BiVP) in HF Patients with AF who need atrial-ventricular node ablation.

A research study to evaluate the impact of a novel care pathway for patients diagnosed with Heart Failure within Chiltern CCG, supported by an integrated clinical patient record. Assessment of patient outcomes following implementation of Care4Today(R) Heart Failure Platform.

This single center randomized controlled trial will involve 50 medically stable outpatients with HF, reduced ejection fraction, and previously implanted ICD or CRT-D devices followed longitudinally on the Abbott Medical Merlin remote patient monitoring network. Patients will be randomized in a 1:1 fashion to usual care plus a remotely administered home based weekly prescription for aerobic exercise (intervention) or usual care alone (control). Usual care will include regularly scheduled visits with the clinical heart failure care team and medical therapy as prescribed by that team. The exercise prescription will be created by an exercise physiologist after incorporating remotely collected data from a patient directed smartphone app assessing HF symptom severity, vital signs, weight, and blood sugar, implantable device measures of physical activity, heart rate, heart failure volume status and heart rhythm, and Fitbit measures of physical activity.

Heart failure is a syndrome that is defined by distinctive clinical, hemodynamic, and neurohormonal findings. HF represents a final common pathway for many different cardiovascular diseases, including coronary disease, hypertension, Valvular disease, and many primary heart muscle diseases. Clinically, HF patients experience dyspnea, fatigue and diminished exercise tolerance, reflecting elevated left and/or right ventricular filling pressures and decreased cardiac output.

Cardiac resynchronisation therapy (CRT) is an established treatment for severe systolic heart failure with well documented benefits in symptom improvement and reduction of morbidity and mortality. However, upto 30% of patients do not respond to treatment despite fulfilling the recommended indications. Lack of clinical response may be the result of imperfect left ventricular lead placement in the veins around the heart with conventional techniques. Optimum lead placement may constrained by coronary venous anatomy and may overlie scarred heart muscle or may not be at the site of latest electrical depolarisation. In a further 10% of patients, conventional left ventricular lead placement is not possible for other technical reasons. Left ventricular endocardial lead placement may overcome the limitations and allow placement to be guided by echocardiography, electrical mapping and the pattern of heart muscle scarring. We aim to investigate if targeted left ventricular endocardial lead placement improves exercise capacity, heart failure symptoms, heart function and size, heart pumping efficiency and biochemical markers of heart strain. Each parameter will be assessed independently and as part of a composite cardiac performance score. Patients with heart failure will be enrolled who require an endocardial left ventricular lead on clinical grounds as either conventional left ventricular lead implantation has technically failed or they have clinically non-responded to CRT.

Targeted population: Patients with heart failure causing hospitalization during the last twelve months. Hypothesis: The number of all cause deaths and hospitalizations will be smaller for the Telecardiology group than for the reference group (standard follow-up care). An 18 months period of observation is required. Main goal: To compare the rate of all cause deaths and hospitalizations of patients with heart failure between the Telecardiology group and the reference group after 18 months of monitoring.
