Active clinical trials for "Heart Failure"

Ivabradine, a selective inhibitor of the If current in the sinoatrial node, provides heart rate reduction and leads to a reduction in heart failure hospitalizations. For this reason, the American College of Cardiology (ACC) and the American Heart Association (AHA) guidelines provide a class IIa recommendation for ivabradine in stable heart failure patients with LVEF 35% and New York Heart Association (NYHA) class II-III symptoms who are on a beta blocker at maximum tolerated dose with a resting heart rate of 70 beats per minute or greater. While ivabradine leads to improvement in outcomes in stable NYHA class II-III chronic heart failure patients, its role in class IV, stage D heart failure, and cardiogenic shock is less clear. Ivabradine's effect on acute cardiogenic shock has been evaluated by two recent studies. In the MODIFY trial, a randomized control study evaluating ivabradine in patients with multiorgan dysfunction, the addition of ivabradine did not result in significant heart rate reductions or other positive clinical outcomes. However, a small prospective trial demonstrated a significant decrease in heart rate and NT-proBNP with the addition of ivabradine in patients with acute cardiogenic shock on dobutamine. While few data investigate ivabradine's role in acute cardiogenic shock, it has yet to be studied in heart failure patients on long-term inotropic therapy. Inotropes such as dobutamine and milrinone result in tachycardia and may lead to ventricular arrhythmias. Moreover, patients on chronic inotropes are typically off beta blockers and have few pharmacological options available to help reduce heart rates. Ivabradine may have a role in decreasing heart rate and improving outcomes in patients on chronic inotropes. Given the benefits of ivabradine in stable chronic heart failure patients, we plan to perform a study investigating the role of ivabradine in NYHA Stage D patients on home inotropes. Our primary objective is to analyze changes in two cardiac biomarkers, NT-proBNP and high-sensitivity troponin. Our secondary outcomes include changes in noninvasive echocardiographic hemodynamics, changes in arrhythmia burden, and heart failure symptom modification based on 6-minute walk test results.

This study is a randomized controlled trial that tests the effectiveness of a novel intervention called the Push-Pull-Hold program on improving self-care in patients with heart failure. This intervention was developed based on our previous quantitative and qualitative findings and existing psychological concepts. Results would inform current understanding of the intention-behavior link in self-care and inform future policy and intervention development to improve patient and caregiver outcomes.

It is the aim of the study to prove, if intravenous supplementation with ferric carboxymaltose in iron-deficient patients with heart failure with reduced ejection fraction (HFrEF) leads to better exercise training effects compared to exercise training without previous iron supplementation.

1. Summary of Clinical Investigation A summary of the clinical investigation is provided below and includes the primary objective of the study, the safety and feasibility endpoints, the number of subjects to be enrolled, the study duration, the subject follow-up and the inclusion/exclusion criteria. Primary Objective The primary objective of the study is to evaluate the safety and feasibility of the alfapump® System indication for use in the management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients who have an eGFR of > 15 to < 60 mL/min/1.73m2. Study Endpoints Primary Safety Endpoint The primary safety endpoint will be an assessment of the occurrence of adverse events (AEs) and serious adverse events (SAEs) related to: Surgical implant of the alfapump® Device malfunctions Dialysate infusion Secondary Safety Endpoints The secondary endpoint will be an assessment of: Time to first hospitalization related to fluid management after the activation of the alfapump® System and initiation of dialysate infusion has occurred Rate of occurrence of re-hospitalizations related to fluid management All-cause mortality Assessment of Feasibility for Fluid Management in Heart Failure Indication The feasibility of the alfapump® System for management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients with renal dysfunction will be assessed by the net fluid balance as measured by the ability of the alfapump® System to move more fluid to the bladder than dialysate instilled.

INVESTED will test the hypothesis that high dose trivalent influenza vaccine will reduce cardiopulmonary events to a greater extent than standard dose quadrivalent influenza vaccine in high-risk cardiovascular patients with a recent history of myocardial infarction or heart failure. The trial will enroll 9300 participants over one Vanguard (pilot) season and three additional influenza seasons. The primary endpoint will be a composite of all-cause mortality or cardiopulmonary hospitalization.

Randomized controlled trial with two groups looking at post hospital care for patients who were admitted with congestive heart failure. The control group includes standard of care provided to the patients after discharge including a hospital employed community health worker. The intervention group receives a specially trained GrandAide following the GrandAide model for post acute care. Difference in ER visits and readmissions was measured.

The aim of the study is to examine the pharmacokinetics and pharmacodynamic properties of Levosimendan in cardiac surgery patients with pulmonary hypertension and impaired right ventricular function.

In the DAPA-HF trial, the use of dapagliflozin, an inhibitor of sodium-glucose cotransporter 2 (SGLT2), reduced significantly the risk of worsening heart failure or death from cardiovascular causes compared to placebo among patients with heart failure (HF) and a reduced ejection fraction. This new drug offers a very potent and interesting therapeutic pathway since it reduces clinical congestion, it preserves glomerular renal function, does not appear to cause symptomatic clinical hypotension and improves symptoms and quality of life compared to placebo. Advanced heart failure patients with reduced ejection fraction represent a small and severe subgroup of heart failure of patients with frequent worsening heart failure events and high rates of death. The effect of dapagliflozin in this subgroup of patients was not assessed in the DAPA-HF study. The therapeutic profile of SGLT2 inhibitors appears to be of high interest, since this group of patients has a poor tolerance to usual heart failure drugs, frequent worsening renal function and congestive symptoms persistence with poor quality of life scores. Soluble urokinase-type plasminogen activator receptor (suPAR) is a signaling glycoprotein considered to be involved in the pathogenesis of kidney disease. It is associated with the risk of acute kidney injury in different clinical and experimental situation. It is also a new validated biomarker predictive of adverse clinical outcome in heart failure patients. This biomarker allows a better risk stratification in heart failure patients after adjustment for Nt-proBNP. As a useful biomarker implicated in both heart failure and acute kidney injury, suPAR seems to be an interesting biomarker to assess cardio-renal benefits of dapagliflozin. The aim of this study is to investigate if a treatment by dapagliflozin reduces significantly suPAR compared to placebo in a population of advanced heart failure patients, candidates to heart transplantation. The effect of dapagliflozin compared to placebo will also be assessed on other secondary heart failure outcomes in this patient population.

The aim of this study is to evaluate the effectiveness of a Multimedia Symptom Management Program on increasing coping strategies, reducing symptom distress and depression, and improving HRQoL in patients with HF.

This is a pilot, multicenter, real-world, single-visit, low risk, phase IV interventional study to efficiently identify new cases of heart failure (HF) Stage C in subjects who are at risk of cardiovascular (CV) disease in high-volume ambulatory primary care settings in 3 countries in Central America.
