The purpose of this study is to collect surface electrograms from standard and several non-standard configurations in patients with long QT syndrome, heart failure, cardiac resynchronization therapy or wide QRS during a routine outpatient a
Cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) is indicated for patients with low ejection fraction and persistent symptoms of heart failure despite medical therapy and a wide QRS-complex, preferably with a left bun
The purpose of this study is to assess the efficacy, tolerability and safety of dronedarone versus placebo in patients with symptomatic congestive heart failure (CHF) and left ventricular dysfunction (LVD) when added to evidence based treat
The presence of chronic obstructive pulmonary disease (COPD) would confer increased in-hospital mortality and length of hospital stay in patients with acute decompensated heart failure Assess the (1) prevalence of COPD in patients who are h
"Cardiovascular Imaging and Biomarker Analyses (CIBER)" is a single-center, prospective and observational study evaluating the expression of novel biomarkers in patients undergoing cardiacvascular imaging within clinical routine care. It is
Diabetes mellitus is among the top 10 causes of death worldwide with an increasing incidence. Patients with diabetes are at risk of developing heart failure which is characterised by significant changes in the heart muscle including scarrin
The purpose of this study is to determine the effect of biofeedback-relaxation combined with cognitive behavioral therapy on clinical, physical and psychological outcomes in patients with heart failure.
The current study aims to investigate whether telemedical monitoring in patients with terminal heart failure and an implanted left ventricular assist device (LVAD) has an influence on LVAD-associated complications, hospitalization rates and
In patients with advanced volume overload, minimally invasive ultrafiltration treatment in the acute phase can have a positive effect on clinical outcome. The aim is to collect treatment data in the context of a prospective registry of the
The aims of this randomized, clinical trial are to develop and test a multileveled pharmacy-based program to improve the care of patients with heart failure. Risk factors for deterioration of heart failure will be determined including poor
The primary objective of this study is to demonstrate that in patients with recuperated/normalized left ventricular function, defined as an ejection fraction (EF) ≥ 50%, after implantation of cardiac resynchronization therapy, device treatm
Medtronic, Inc. is sponsoring the OptiVol® Care Pathway Study, a prospective, randomized, multi-center, post-market clinical trial in the United States.
The purpose of this study is to determine the effect of passive exercise on systemic endothelial function in elderly patients with chronic heart failure.
The principal aim is to analyze total left and right ventricular activation time in different CRT device programming algorithms (SyncAV) measured by non-invasive electrophysiology
Evaluation of the effect of short term activation/deactivation of biventricular pacing (BivP) of the CRT (during routine CRT interrogation) on vascular function as assessed via retinal vessel analysis (RVA), in patients treated with CRT.
To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.
This clinical trial aims to compare the efficacy and safety of acetazolamide versus metolazone as adjunctive treatments to standard therapy in patients with acute decompensated heart failure (ADHF). ADHF is a life-threatening condition, and
Approximately one billion people suffer from hypertension worldwide. At least 10% of this population, that is, 100 million people, also suffers from associated chronic conditions namely, atrial fibrillation (AF), obesity, arterial stiffness
Patients with poor heart function can, in certain situations, have a further weakening of the heart muscle such that it becomes difficult to provide enough blood to the brain and other organs. In these cases, heart function can be supported
The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound technique called subharmonic-aided pressure estimation (S
