Active clinical trials for "Heart Failure"

The PRIME-HF study is a multi-center, patient-level, randomized, open-label study of approximately 450 patients with reduced (left ventricular ejection fraction) LVEF of ≤ 35% and heart-rate ≥70 beats per minute (bpm) who are being discharged from the hospital following stabilization from acute heart failure (HF)(primary or secondary) and will be randomized to a treatment strategy of predischarge initiation of ivabradine or usual care. All participants should have a follow-up visit within 7-14 days of hospital discharge. Heart rate and systolic blood pressure will be assessed at this clinical visit. For participants randomized to predischarge initiation of ivabradine and on ivabradine 5mg BID, the heart rate may be used to adjust the dose the dose to 2.5mg BID or 7.5mg BID. For participants randomized to usual care, ivabradine may be initiated at the provider's discretion. All participants will have a second follow-up study visit 6 weeks (42 +/- 14 days) post-discharge. Heart rate, systolic blood pressure and quality of life (KCCQ and PGA) will be assessed. For participants already taking ivabradine in either treatment group, the heart rate may again be used to adjust the dose of ivabradine. For participants not yet receiving ivabradine, it may be initiated at the provider's discretion. All participants will receive a 90 (+/-7) day post-discharge phone call by site to assess for event status and tolerability of ivabradine. All participants will have a final study visit at 180 (+/-14) days post-discharge. Heart rate, systolic blood pressure and quality of life (Kansas City Cardiomyopathy Questionnaire and Patient Global Assessment) will be assessed. The attending physician may initiate ivabradine per usual care clinical practice. The primary hypothesis of the PRIME-HF study is that, compared with usual care, a treatment strategy of initiation of ivabradine prior to discharge for a hospitalization with acute HF will be associated with a greater proportion of participants using ivabradine at 180 days. Secondary objectives are to assess the impact of predischarge initiation of ivabradine on:Heart Rate (Change in heart rate from baseline to 180 days and Median heart rate at 180 days) and Patient-Centered Outcomes (Kansas City Cardiomyopathy Questionnaire (KCCQ) and Patient Global Assessment (PGA)). Tertiary objectives will be to explore the impact of predischarge initiation of ivabradine on other assessments of evidence-based implementation of ivabradine and beta-blockers at 180 days. Evaluations will incorporate data based on whether or not indication status was retained and whether or not an ivabradine prescription was provided. Tolerability of ivabradine and adverse events during study follow-up.

The main purpose of this study is to determine whether dietary nitrate supplementation via concentrated beetroot juice improves central and peripheral cardiovascular control and physical capacity in patients with systolic heart failure.

The purpose of this study was to collect safety and tolerability data on LCZ696 in eligible PARADIGM-HF patients who received open-label investigational drug. The parent PARADIGM-HF (NCT01035255) trial was terminated early due to compelling efficacy of LCZ696 in patients with heart failure with reduced ejection fraction (HFrEF) after the final pre-specified interim analysis in March 2014.

The present study will evaluate whether treatment with daily remote ischemic conditioning for a 28±4-day period induces beneficial effects in subjects with and without chronic ischemic heart failure in terms of improved left ventricular contractile function and exercise capacity.

Implantation of internal defibrillators, capable of monitoring the heart and shocking life threatening arrhythmias back to normal rhythm, for patients with severe heart failure increases the probability of survival. Arrhythmias of the atria of the heart are common in these patients. Administering a direct current electrical shock under anesthesia (cardioversion) is the method of choice to reestablish normal sinus rhythm in this instance. Safety and efficacy of external electrical cardioversion (CV) in patients with ICDs was demonstrated in several studies. Safety of internal cardioversion (shocking the heart back into normal rhythm via the implanted defibrillator) was described in several smaller trials. Performing external instead of internal cardioversion in patients with implanted ICDs is more feasible for most hospitals, as CV can be performed without a programming computer and an additional specialist present, e.g. on the intensive care ward, and device interrogation can be done after CV at the remote ICD/pacemaker clinic. No scientific data on safety and efficacy endpoints comparing internal vs external CV is currently available. The aim of the study is to compare external vs internal electrical cardioversion for atrial arrhythmias and establish a safety and efficacy profile for external and internal cardioversion in large cohort of ICD patients.

This is a research study being conducted to better understand the impact of exercise training on changes on the structure and function of the heart. Exercise training in patients with heart failure has been shown to be beneficial at decreasing symptoms of heart failure and improving overall functional capacity or capacity to exercise. However the mechanisms responsible for this are still unclear. This study will look specifically at how exercise creates changes within the hearts filling ability, the hearts pumping strength as well as the hearts ability to rebuild.

The purpose of this study is to evaluate the safety, tolerability and mechanistic effects of spironolactone, an aldosterone receptor antagonist, on sympathetic nervous system activity and right heart function and remodeling in patients with chronic right heart failure.

The objective of the study is to test whether 12 weeks of structured supervised exercise training on top of usual care improves functional capacity in patients with end-stage heart failure with continuous flow left ventricular assist device (LVAD).

This is a randomized, double-blind, placebo-controlled, sequential design, multicentre study in patients with moderately impaired systolic function undergoing CABG surgery. Twenty four (24) patients scheduled for elective bypass surgery will be randomized (up to approximately 33 patients if replacements are needed). The objective is to investigate safety and tolerability of AZD8601 following epicardial injection in patients undergoing Coronary Artery Bypass Grafting (CABG) surgery with moderately impaired systolic function. At Visit 3 patients will receive either AZD8601 or placebo as epicardial injections and will then be followed up at 14 days (telephone visit) and 1, 3 and 6 months (on-site) post-surgery.

This is a prospective multicentre (N=15), stepped-wedge randomized trial that aims to evaluate the benefit of a protocolised comprehensive care bundle for early management of acute heart failure in the ED.
