Active clinical trials for "Heart Failure"

This study will better understand the post-capillary pulmonary hypertension in heart failure, to determine its prognostic role and to consider specific treatment of different forms of pulmonary hypertension in post-capillary pulmonary heart failure.

The investigators would like to find out if AESCULON®, a new device that non-invasively and continuously measures cardiac output using electrical cardiometry, works as well as one existing method--Fick method in patients undergoing cardiopulmonary exercise testing.

The purpose of this study is to evaluate echocardiographic markers of cardiac function to assess the ability of patients to successfully end VA-ECMO support.

The Cutaneous Heart Sounds Data Collection During CRT Optimization study is an acute, prospective, non-randomized multi-center feasibility clinical trial. The purpose of this clinical trial is to collect data to assist in the testing and finalization of a hemodynamic sensor-based cardiac resynchronization therapy (CRT) optimization scheme.

This study will collect data, from an implanted Cardiac Resynchronization Therapy-Defibrillator (CRT-D) device, to further evaluate a new feature for future heart failure devices.

The purpose of this study is to collect sensor data from patients with implanted cardiac resynchronization devices who exhibit phrenic nerve stimulation.

A prospective post-market study to evaluate the performance and clinic usability of heart failure risk status (HFRS) feature on CareLink.

The main purpose of this study is to analyse test-retest-reliability of functional quantification of endothelial dysfunction through puls-amplitude-tonometry in patients with heart failure with preserved/reduced ejection fraction, pulmonary hypertension, arterial hypertension and diabetic nephropathy. In the same group, test-retest-reliability of circulating endothelial cells as well as test-retest reliability of non invasive cardiac output Monitoring will be observed and analysed.

The purpose of this study is to assess the relationship between cognitive impairment, patient self-management, health, and health service use in adults with heart failure (NYHA Class 2 and 3). The research questions are: How is cognitive impairment (memory, attention, global and executive function) related to various aspects of impaired self-management (knowledge of adherence, adherence to sodium restriction and medications, symptom monitoring of weight changes, and decision and action to seek care)? How are these relationships altered when adjusting for medical, demographic, and psychosocial factors? What are the relationships among degree of cognitive impairment, quality self-management, health status, and health service use?

The purpose of this study is to evaluate the demographic, clinical, prognostics characteristics of 1,200 patients admitted with clinical diagnosis of decompensate heart failure in a group of 60 hospitals representative in different regions.
