Active clinical trials for "Heart Failure"

The aim of the present study is to investigate whether in patients with chronic heart failure endothelial dysfunction and baroreceptor function is altered by ingestion of a flavonoid-rich dark chocolate in comparison to placebo chocolate (Nestlé Placebo Chocolate) on top of standard medication. Moreover, we will evaluate the effect of chocolate on oxidative stress, platelet adhesion as well as systemic inflammatory response such as C-reactive protein and pro-inflammatory cytokines in patients with chronic heart failure.

Improvement of heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implanted device.

This study is to demonstrate the safety and tolerability of a single oral dose of BAY60-4552 in a single dose escalation design. Furthermore, this study examines the changes in hemodynamics after application of the test substance.42 hospitalized stable patients with chronic heart failure will be included. Several measurements will be performed to test how good the drug works and wether there are any unwanted reactions to the drug (e.g. blood tests, ECG, heart rate, blood pressure, adverse events). After a observation period the patient will be discharged from the hospital.

Improvement in heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implanted device

The purpose of this study is to determine whether a nurse-led, comprehensive disease management program is effective in reducing recurrent hospital admissions and deaths in community dwelling patients with moderate to severe heart failure.

Evaluate appropriate performance of Electronic Repositioning™ (ER) in the clinical routine, cumulative incidence of phrenic nerve stimulation (PNS) & success rates of Electronic Repositioning (ER) to remove it, various incl. left ventricular pacing (LVP) thresholds and PNS

It is the purpose of the study to show the benefit of the endocardial catheter ablation by pulmonary vein isolation in patients with persistent or longstanding persistent atrial fibrillation, low LVEF and requiring ICD or CRT-D therapy compared to the best medical treatment with antiarrhythmic drugs.

Heart failure remains an increasing cause of morbidity and mortality in the United States even in the face of recent advances in the treatment of cardiovascular disease. There is an urgent need to reevaluate the treatment of heart failure. Shifting substrate utilization used in energy metabolism from fatty acids to glucose is beneficial to the heart presumably by increasing the efficiency of ATP production. Several new drugs for the treatment of cardiac ischemia work by this mechanism. There is increasing evidence that patients with heart failure may also benefit by the same type of intervention. Patients with heart failure are known to have low serum thiamine levels because of poor dietary intake and increased urinary excretion. Inadequate thiamine will deleteriously shift substrate utilization from glucose to fatty acids. We hypothesize that thiamine supplementation will be beneficial for patients with heart failure by increasing glucose and decreasing fatty acid utilization. This will be initially tested in a pilot double-blinded placebo controlled study of thiamine supplementation in diabetic and non-diabetic patients presenting to the emergency department with acute decompensated heart failure.

We want to evaluate the utility of statins on heart function according to potency. Patients with chronic ischemic heart failure are administered pitavastatin 4mg or pravastatin 10mg for 52 weeks. Then we evaluate the effect of pitavastatin and pravastatin primarily on rate of hospitalization for cardiovascular cause and lipid profile secondarily biomarker, echocardiography parameter, 6-minute walk, change of NYHA class distribution, cardiovascular mortality.

This is a dose-ranging clinical study to evaluate the feasibility, safety, and tolerability of 3 different doses of immunoselected, culture expanded, nucleated, allogeneic MPCs in subjects who have cardiomyopathy of both ischemic and idiopathic etiology.
