Active clinical trials for "Heart Failure"

End stage heart failure is characterized by a critical inability of the heart to meet the organism's blood demand even under resting conditions. Heart transplantation (HTx) is the established therapeutic approach in the treatment of end stage heart failure and still the gold standard treatment. Left ventricular assist devices (LVADs) are considered as a vital therapeutic option to temporarily or permanently assist the failing circulation. The hemodynamic vascular consequences of implanting LVADs have not been studied in detail. The aim of the study is to investigate the effect of LVAD implantation compared to heart transplant (HTx) on micro- and macrovascular function in patients with end stage heart failure.

The main aim of this study is to conduct a randomized control trial to compare MobileMedMinder, a mobile phone based medication reminder software product, with currently accepted and empirically supported methods for increasing medication compliance through reminders and tracking.

Objective target of the registry is to investigate the prevalence of SDB as well as the clinical characteristics of patients with and without SDB as well as the predominant type of sdb. For this purpose data from patients suffering from chronic, symptomatic heart failure with impaired left ventricular ejection fraction will be collected prospectively.

It is routine practice for a cardiologist to perform a battery of tests to assess the degree of heart failure. The purpose of this study is to establish a non-invasive method to reliably predict cardiac output state in real-time in children and adolescents with heart failure in an outpatient setting. This study will rely on the use of near infrared spectroscopy monitors to measure cardiac output in the outpatient setting.

The purpose of this study is to evaluate the effects of MultiPoint Pacing (MPP) on cardiac hemodynamics assessed by pressure-volume loop during MPP at implant. NYHA functional class assessment and echocardiographic measurements are performed at 3 months and 12 months post-implant to characterize long-term effect of MPP.

The study was aimed to verify the effects of Hypertonic saline solution (HSS) and a moderate sodium (Na) restriction plus high furosemide dose in the short term (hospitalization time) and a moderate Na restriction in the long term on readmissions and mortality in patients in III NYHA class.

Heart failure (HF) affects over 5 million Americans with HF morbidity reaching epidemic proportions. Annual rates of new and recurrent HF events including hospitalization and mortality are higher among African Americans. In this study, the investigators are testing an interdisciplinary model for heart failure care, with focus on enhancing self management and use of telehealth, which has significant potential to improve self management and outcomes. The main purpose of this study is to learn how to help African Americans with heart failure care for themselves at home. We hope to find out if a team including a nurse and community health navigator using a computer telehealth device can help people with heart failure stay healthier. The team will help people with heart failure to manage their medication, monitor their symptoms and weigh themselves every day after they leave the hospital. The team will also help people with heart failure learn to solve problems that may keep them from following their treatment plan.

The purpose of this project is to conduct a preliminary test of the feasibility of a multi-micronutrient intervention to improve micronutrient status, cardiac function and quality of life in Veterans with Congestive Heart Failure (CHF).

Heart failure is a common, costly, disabling and potentially lethal condition. Despite well recognised and proven drug therapies, many patients remain breathless on exertion. A special pacemaker (cardiac resynchronisation therapy) may help improve symptoms of breathlessness and survival by restoring coordinated beating of the heart. However, despite careful planning and the knowledge of the most appropriate selection criteria, up to a third of patients do not get the desired beneficial effects after the pacemaker has been implanted. The implantation of the special pacemaker requires three leads (wires) to be inserted within the heart. Currently this is undertaken under X-ray guidance. Some patients may have scarring of the heart muscle due to previous heart attacks or their underlying condition. The X-ray technique cannot see this and therefore the doctor may implant the lead in such an area of scar tissue. Cardiac magnetic resonance imaging (CMR) can demonstrate these areas of scar. The study aims to investigate whether CMR can better predict where the wires should be placed. The CMR pictures will be taken before the patient has the special pacemaker implanted.

Heart Failure with Preserved Ejection Fraction (HFpEF) and Pulmonary Hypertension (PH) can be diagnosed noninvasively by Exercise Echocardiography (ExE) and Cardiopulmonary Exercise Testing (CPX) as compared with gold standard invasive hemodynamic assessment.
