Active clinical trials for "Heart Failure"

This is a registry study. This is an observational, non-randomized, open, long-term project to collect biological samples (e.g. tissue and blood samples) in addition to clinical information and laboratory test results, from end-stage patients who undergo LVAD implantation and/or heart transplantation. There are no investigational treatments, drug or procedures associated with participation in registry activities. Data collection will not immediately influence the course of treatment for any patient.

A computerized registry of cardiovascular disease patients in a large health maintenance organization in Israel. The registry is aimed to be used by health professionals to identify cardiovascular disease patients and to follow the courses of their illnesses and risk factors.

The primary objective of this study is to assess whether the urinary sodium/creatinine or chloride/creatinine ratio might predict successful downtitration of loop diuretics in patients with stable heart failure without clinical signs of volume overload. In addition, this study will provide information on loop diuretic efficiency and urinary electrolyte composition after intake of diuretics in stable outpatients with heart failure.

Treatment of ischemic heart failure.

Rationale: End-stage congestive heart failure is a serious invalidating condition with a poor prognosis and increasing incidence. Non-randomized observations showed peritoneal dialysis (PD) in these patients to improve clinically from NYHA stadium III-IV to as low as NYHA stadium I-II. A randomized trial is needed to test whether PD improves symptoms in this condition and to find an optimal scheme. Objective: To improve symptomatology in severe chronic failure patients. Study design: Open, parallel intervention trial comparing 2 schemes of peritoneal dialysis with icodextrin (Extraneal®) with standard medical therapy.. Study population: Patients with chronic refractory left ventricular congestive heart failure (LVEF < 30%, older than 18 years). Intervention: Peritoneal dialysis with one (night) or two (night and day) dwells with icodextrin (Extraneal®). Main study parameters/endpoints: Reduction in NYHA classification of symptomatic Congestive Heart Failure at 8 months after start of PD therapy. Burden of congestive heart failure: measured by reduction in unfavorable days (noted by patients in diaries and including days of hospitalization for CHF-deterioration and death).

A placebo controlled, double-blind and randomized study to assess different doses of a new drug (BAY58-2667) given intravenously, to evaluate if it is safe and can help to improve the well-being of patients with acute decompensated heart failure.

Cardiac resynchronization therapy (CRT) has shown improvement in mortality and morbidity in patients with left ventricular systolic dysfunction and congestive heart failure. Additionally in CRT patients it has been demonstrated that optimizing paced/sensed atrioventricular (AV) and interventricular (V-V) timings leads to immediate hemodynamic benefits and further improves cardiac function. Recent studies have shown that optimal paced/sensed AV and V-V delays change over time, which raises the question of how often optimization should be repeated. Thus, frequent re-optimization of these delays might be beneficial for maintaining significant improvement of cardiac function. However, it remains to be evaluated whether timing optimization may be beneficial on patients who have received CRT for a number of years and are now having the CRT device replaced.

Track changes in non-invasive central venous pressure across hospital stay and relationship with readmission

The overactivity of sympathetic nervous system is worsening the hemodynamic state of heart failure patients. The present study is planned to reduce the sympathetic tone in patients with severe heart failure by renal nervous denervation.
