Active clinical trials for "Heart Failure"

The proposed study seeks to explore the possibility of significantly increasing the success rate (from the current rate of 28%) of clinically significant Transdermal Fluid Removal (TFR) in heart failure patients. It seeks to further understand the device and patient characteristics influencing successful clinically relevant fluid removal and to measure any patient-defined benefits. It also wishes to explore the patient experience of the removal.

Heart Failure (HF) is a cardiovascular disease secondary to a structural and / or functional alteration of the heart that prevents its correct function. The Cardiac resynchronization therapy (CRT) aims to restore atrioventricular, inter and intraventricular synchrony in patients with systolic HF and wide depolarization of the ventricles (QRS). Although CRT has been shown to be effective, the rate of non-responders is high (30-50%). One of the proposed reasons for the lack of response to the CRT is the lack of intrinsic conduction, since most of the time CRT is administered using biventricular stimulation (BiV). One of the limitations to achieve ventricular fusion are the dynamic physiological variations of the auriculo-ventricular (AV) interval. The SyncAVTM algorithm is a new dynamic algorithm that manages to adjust the AV intervals outside the clinic. The design of the present clinical study is post-marketing, prospective, multicenter, randomized and blind for the patient and the central echocardiography laboratory. The objective of this study is to assess whether CRT with ventricular stimulation with fusion using the SyncAVTM algorithm is superior to CRT with conventional BiV stimulation in the population for which its use is foreseen. The data will be collected in at least the Selection / Baseline Visit and in the Visit of Follow-up at 6 Months. The study population are subjects to whom an Abbott Medical CRT has been implanted with SyncAVTM® Stimulation function that go to the participating sites in the study. The main objective of the study is to assess whether CRT with ventricular stimulation with fusion using the SyncAVTM algorithm is superior to CRT with BiV stimulation conventional in terms of the rate of responders. The main endpoint is the determination of significant differences between conventional BiV stimulation and ventricular stimulation with fusion using the SyncAVTM algorithm in terms of the percentage of patients responding to CRT therapy with echocardiogram. The duration of the clinical study is estimated at 24 months with a recruitment period of 18 months and a patient follow-up of 6 months. The number of subjects that is planned to be recruited is 176. The inclusion will be competitive and there is no inclusion number determined per site.

The present study will randomize 50 symptomatic heart failure patients with severely reduced left ventricular ejection fraction (LVEF) and a true left bundle branch block to either direct HIS-pacing or biventricular pacing and follow them for at least six months. The outcome is how often it is possible to achieve HIS-pacing at implant and during follow-up and if HIS-pacing leads to differences in symptoms or measurable clinical parameters as compared to biventricular pacing.

Loop diuretics are the main therapy for decongestion of patients with advanced acute heart failure. However, these patients often develop diuretic-resistance or even diuretic-refractoriness. In order to overcome such resistance to diuretic, the clinician can increase the dose of furosemide, or change the way of administration (continuous infusion versus boluses) or associate a different class of diuretics (thiazide diuretics, K+-sparing diuretics) up to the addition of low doses of inotropic agents to improve renal perfusion. At the present time there is no evidence in literature in advanced acute heart failure patients about the superiority of the treatment with furosemide in continuous infusion or in intermittent boluses. The aim of the study was to evaluate the efficacy of furosemide in boluses versus continuous infusion in advanced acute heart failure.

AZD9977 is an oral, selective mineralocorticoid receptor (MR) modulator. AZD9977 is a partial antagonist and partial agonist in reporter gene assays and has a different interaction pattern with the MR compared to eplerenone. This study will assess the pharmacokinetics (PK) of four different Formulations of AZD9977 (Part A) and influence of food and lower dose of a selected formulation (Part B) in healthy male subjects.

This study compares the effectiveness of a 6-week Energy Conservation + Problem Solving Therapy Intervention to Health Education Intervention for reducing the fatigue impact and fatigue level and improving the level of participation in instrumental, leisure, and social activities in people with heart failure associated fatigue. Half of the participants received Energy Conservation + Problem Solving Therapy Intervention, and the other half received Health Education Intervention.

Evolocumab has been able to reduce the incidence of cardiovascular events in patients that had at least one cardiovascular risk factor [28]. In patients with chronic HFrEF, as we mentioned before, treatment with statins is not recommended as it has not shown benefits in improving its prognosis. However, CAD control stands as an approach that could improve the course of the disease by preventing microlesions that further weaken the heart. A recent multicenter study, the BIOSTAT-CHF [3436], was performed to determine whether the PCSK9-LDLR axis could predict risk in patients with HF. A multivariate analysis, which included BIOSTAT risk scores, LDLR, and statin treatment as covariates, revealed a positive linear association between PCSK9 levels and the risk of mortality and the composite endpoint (death or HF-related hospitalization). A similar analysis for LDLR revealed a negative association with mortality and the composite endpoint. Future studies must assess whether PCSK9 inhibition will result in better outcomes in HF. There is an unmet clinical need: blockade of the neurohormonal activation has provided advances in patients with HFrEF, yet mortality and morbidity remain unacceptably high. Approaching a strict control of lipid levels and CAD with evolocumab in stable HFrEF of ischemic ethology may represent a complementary pathophysiological pathway to reduce mortality and morbidity. The burden of CAD provides a solid rationale for testing the value of evolocumab in HF patients. Therefore, a pilot trial is proposed to evaluate the beneficial effect of evolocumab by surrogate biological markers before considering an event analysis study. Evolocumab reduces the risk of cardiovascular events in patients with established atherosclerotic disease, so this drug could play a role in HFrEF of ischemic etiology, by limiting macro- and micro-vascular coronary disease progression. In HFrEF patients due to ischemic etiology, there is a continuous troponin release due to persistent myocyte injury, which has been associated with adverse outcomes. Our hypothesis is that evolocumab may have the potential to reduce circulating hs-TnT levels, as a surrogate of myocyte injury due to atheroma progression in HFrEF. A positive result in this EVO-HF Pilot study may lead to the set-up of a large-scale multicenter prospective and randomized events study analyzing the role of lipid-lowering treatment by means of evolocumab in HFrEF of ischemic etiology

In the current application, the investigators propose to elaborate upon, reconstruct and advance to pivotal trial readiness a recently validated mobile application (HeartMapp), designed for the ecological momentary assessment and treatment of individuals with Heart Failure (HF). Presently, HeartMapp includes physiological modules (PM) that support self-monitoring and exercises that promote heart health, and cognitive modules (CM) that track and enhance cognitive functions. During the first three-months, the investigators will finalize the cognitive training modules within HeartMapp and release through the quality management system. At the completion of software development, the investigators propose to test the relevant usage and progression variables of the algorithm that will be used to direct engagement with the app. The investigators will conduct a single arm, open label, pilot clinical trial to examine feasibility and initial efficacy of the HeartMapp+CT (HeartMapp and computerized plasticity-based adaptive cognitive training). The term "CT" refers to computerized training. The study will enroll 32 adults aged 40 and older with a diagnosis of HF and over sample by 25% to reduce attrition for a total of 24 participants enrolled at the end. Participants will complete follow-up assessments at 3- and 6-months after enrollment.

In contrast to the treatment of HF with reduced EF, information to guide the pharmacological therapy of patients with HFNEF are lacking and there is no evidence based treatment for patients with HFNEF. Thus, present treatment strategies for HFNEF are largely based on assumptions regarding its pathophysiological mechanisms and on extrapolations from proven strategies used in systolic HF. Till now, no study enlightens the efficacy and safety of beta blockers in HFNEF in a randomised controlled manner although the role of beta blockers in HF with impaired systolic function has been sufficiently time tested leading to their therapeutic approval in that condition. Keeping in view the small reported benefit of beta blockers in HFNEF as mentioned above, there is a need to provide a conclusive proof of their role in this condition as well. Hence, investigators planned to test the efficacy and safety of metoprolol CR in patients with HFNEF in a randomised double blind placebo controlled trial.

This is a randomized trial of the addition of dapagliflozin to patients with or without type 2 diabetes hospitalized with acute decompensated heart failure (ADHF). Participants will be recruited following an initial standard evaluation in the ED and randomized within 24 hours of presentation for ADHF in a 1:1 fashion to protocolized diuretic therapy or dapagliflozin + protocolized diuretic therapy.
