Active clinical trials for "Heart Failure"

The randomized patients with acute heart failure will be stratified based on the presence or absence of a Swan-Ganz catheter and assigned to receive either tezosentan 5 mg/h for the first 30 minutes and 1 mg/h thereafter or matching placebo in a 1:1 manner. The duration of the treatment is 24 hours up to 72 hours. The duration of the follow-up period is 30 days after treatment initiation for death, re-hospitalizations and SAEs followed by a follow-up period of 5 months for vital status.

Heart failure causes significant morbidity and mortality and is the most rapidly increasing cardiovascular diagnosis in North America overall prevalence is estimated at 0.4% to 2.4%. Recently, heart failure with a preserved ejection fraction (HFNEF) was found in up to 50% of patients with symptomatic heart failure. Many studies have demonstrated that HFNEF has a poor prognosis with a mortality rate of up to 8% per year and a 50% chance of needing to be admitted to hospital in the next year. There are no proven therapies for this type of heart failure. Aldosterone blockers (these drugs block a hormone that is elevated in patients with heart failure) are used in other types of heart failure. Our goal is to see if this type of drug improves the function of the heart by looking at the thickness of the heart muscle using MRI. Also we will measure the amount of tissue formation and breakdown in the heart. The trial will be done using both the drug and a placebo so that we can see what effects are due to the drug.

The CardioKinetix Ventricular Partitioning Device (VPD) is intended to isolate the malfunctioning portion of the left ventricle in patients with symptoms of heart failure due to ischemic heart disease. By isolating the malfunctioning portion of the left ventricle, it is hypothesized that the left ventricle will pump more effectively.

This is a prospective, multi-center, randomized, single-blind clinical trial conducted in the United States (US). The objective of the study is to evaluate the safety and efficacy of the HF Pressure Measurement System in reducing heart failure (HF) related hospitalizations in a subset of subjects suffering from HF.

The purpose of this study is to determine the safety profile of iron oligosaccharide in patients with congestive heart failure with a need for parenteral iron.

This pilot study is to prospectively evaluate the benefit of clinicians being able to access ICD device information in a timelier manner and treat fluid overload with a pre-defined pattern using the Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink in Conexus-enabled devices (remote arm) as compared to the same devices without Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink available to the treating physician (standard arm).

Patients with heart failure often have high blood sugar (glucose).

High glucose as well as fluctuations (rapid swings) in blood glucose can contribute to severe hospital complications and even death.

Heart Failure affects 5-6 million Americans and there are about 550 thousand new cases of heart failure every year. There are approximately 3 million hospital admission for acute decompensated heart failure with hospital readmission rate of 20% at 30 days and 50% at 60 day, costing up to 20 billion dollars per year. In our previous study we have discovered that sleep disordered breathing is prevalent in 70% of patients with acute decompensated heart failure. We hypothesize that, detection and treatment of sleep disordered breathing in acute decompensated heart failure patients will reduce episodic hypoxic events during acute decompensation and may decrease hospital length of stay and reduce future readmissions.

The purpose of this study is to determine the effects of candesartan, once daily (QD), on the N-terminal pro-B-type Natriuretic Peptide laboratory marker in subjects with symptomatic heart failure with diastolic dysfunction.
