Active clinical trials for "Heart Failure"

This study will investigate the use of cardiac MRI in patients with standard ICDs and pacemakers to inform how cardiac resynchronization therapy (CRT) can best be implemented in these patient and which patients are the best candidates for CRT.

Recent studies have suggested that the use of left ventricular ejection volume index calculation may aid in the hemodynamic management of critically ill patients. However, a prospective and randomized comparison in patients with heart failure for inotropic dose adjustment has not been described. The objective of this study was to evaluate the efficacy and safety of ejection volume index versus liberal strategy in adjusting dobutamine dose in patients with heart failure and low cardiac output. Methodology: A unicentric, randomized and prospective study will be performed in a comparative manner. Hospital data (test results, medical outcomes, dobutamine dose, complications) of patients will be analyzed for safety and effectiveness. Expected results: The use of ejection volume index is not inferior to the liberal strategy in the initial adjustment of the dose of dobutamine in patients with heart failure.

This is an observational, prospective, single arm, multi-center registry to evaluate the Cordella™ Heart Failure System (CHFS) in up to 250 NYHA Class III HF patients .

As the end stage of almost all cardiovascular diseases, heart failure has become an increasingly common cause of cardiovascular morbidity and mortality worldwide. In China, coronary artery disease (CAD) has become the main cause of heart failure in recent years. CAD combining with heart failure usually predicts poor outcome, with coronary revascularization the most universally used therapy. However, the difference of several types of such therapy has less well been compared. Thus, the study mainly aims to compare different types of coronary revascularization therapies such as Percutaneous Coronary Intervention (PCI),Coronary Artery Bypass Grafting (CABG) as well as Hybrid Coronary Revascularization (HCR), and also make the optimization strategy especially in patients with heart failure. The study also aims to investigate whether disease progression in patients with chronic heart failure (CHF) can be assessed by new biomarkers and determine their diagnostic and prognostic value, relating several cardiac functional parameters to clinical outcome.

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 safety and performance of minimally invasive ultrafiltration. The data will be recorded via an electronic case report form (eCRF); the eCRF runs on a server located in Germany and complies with current data protection regulations. It is intended to include about 300-500 patients with advanced volume overload at a minimum of 10 sites. In addition, data on a disease management programme (in-body measurement and home monitoring) will be recorded in up to 40 of these patients. The treatment data from each patient will be recorded over 12 months. An interim analysis will be performed after 150 patients have been observed for 6 months. The knowledge about ultrafiltration in volume overload obtained from the registry, in some cases in combination with a disease management programme, is intended to improve the body of evidence. In addition, the data will be used for hypothesis generation.

Renal dysfunction, which comprises 10%-40% of acute heart failure patients (AHF), plays an important role in diuretic resistance mechanism. DR-AHF was designed to demonstrate the effectiveness of early tolvaptan (a vasopressin-2 receptor antagonist) add-on therapy in acute heart failure patients with renal dysfunction and clinical evidence of loop diuretic resistance.

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Previous studies have shown that rate control strategy in AF is non-inferior to rhythm control strategy, in terms of stroke and mortality risk. In addition, rate control strategy is associated with lower risk of hospitalization and non-cardiovascular mortality. Therefore, rate control is an essential strategy to improve quality of life, decrease morbidity and prevent tachycardia-induced cardiomyopathy in AF patients. The recommended rate control agents include beta-blocker, nondihydropyridine calcium-channel blocker (CCB), digoxin and amiodarone. However, in heart failure with reduced ejection fraction patient, the medication of rate control were beta-blocker than digoxin. But several clinical observation study show excess mortality in AF patients. Ivabradine, a If inhibitor, it is well-established that a pacemaker current, If current, is functionally expressed in the sinus node . Previous studies have shown that Ivabradine, If inhibitor, significantly reduces sinus rate and improves prognosis in patients with systolic heart failure. Interestingly, several investigators found that hyperpolarization- activated cyclic nucleotidylated channel 4 current (HCN4), the main isoform of the channel responsible for If current, is also functionally expressed in the Atrioventricular node(AV node). Recent data have shown that inhibition of If current slows AV node conduction in animals and humans. Thus, we want to compare the effect of Ivabradine on ventricular rate with digoxin in this study.

A study evaluating the impact of remotely collected data, measured using digital technologies, on the use of guideline-recommended heart failure therapy in adult participants with heart failure.

Chronic, ambulatory heart failure patients will be given ketone ester dietary supplementation to determine therapeutic efficacy, metabolic adaptation, pharmacokinetics, associated cognitive changes, and safety within this patient cohort in order to establish preliminary data to later conduct a multi-center randomized clinical trial.

Mechanical circulatory support, specifically implantable continuous flow left ventricular assist device (CF-LVAD) therapy has been established as a viable treatment for rapidly deteriorating patients suffering from end stage heart failure either as bridge or alternative to heart transplantation. However, a large proportion of these patients experience severe complications in the early postoperative period including right ventricular failure or multi organ failure leading to increased mortality. The leading theory explaining these complications involves exaggerated systemic inflammatory response prior to, during and early after CF-LVAD insertion. Among the cytokines IL-6 appears to play a major role. There is increasing demonstration of the efficacy of a cytokine haemoadsorption (HA) technology in attenuating cytokine response and particularly IL-6 in various inflammatory states and emerging data on the safety of the Cytosorb® device in routine and complex cardiac surgery. The study team hypothesizes that Cytosorb® treatment is feasible and safe in heart failure patients undergoing LVAD insertion and that it is effective in attenuating IL-6 secretion with benefit in the wider inflammatory and metabolic response to this high-risk surgery.
