Active clinical trials for "Heart Failure"

Multi-centre open-label 1:1 randomized clinical trial in chronic heart failure patients on the effect of fluid restriction versus liberal fluid intake on quality of life.

Double-blind, randomized, two-period crossover, placebo-controlled, single-center study, to determine the effect of umeclidinium/vilanterol 55/22 μg compared with placebo on the increase in left systolic chamber function during exercise in patients with COPD, lung hyperinflation and mild to moderate left ventricular dysfunction.

Background: CKD in patients with heart failure (HF) is common and associated with poor prognosis. Despite evidence of benefit with Renin-Angiotensin-Aldosterone-System inhibitor (RAASi) agents, they are avoided due to fear of hyperkalaemia. New potassium binders, e.g. Sodium Zirconium Cyclosilicate (SZC), reduce incidence of hyperkalaemia in CKD-HF patients and hence may help RAASi maximisation, which has not been investigated in an RCT. Purpose: The proposed study will randomise HFrEF patients with stable CKD 3-5 and serum potassium 5-5.0 mmol/L, to receive SZC or placebo while RAASi therapy is maximised. The aim of the study is to examine if SZC is superior to placebo in achieving maximal doses of ACEi/ARB, e.g. Ramipril 10 mg, Candesartan 32 mg; and mineralocorticoid receptor antagonist, e.g. Epleronone 50 mg or Spironolactone 50 mg, avoiding hyperkalaemia. Methods: Eligible patients with eGFR<60 mL/min/1.73m2, heart failure (EF<40%) on none/submaximal dose of RAASi will be randomised to receive 10g TDS of investigational medicinal product (IMP), either SZC or placebo, for 48 hours and in 10 or 5g OD guided by laboratory serum potassium (K+). Every two weeks the RAASi dose will be increased and IMP adjusted according to a strict protocol and guided by laboratory potassium and creatinine. The primary endpoint of the study is achievement of maximal dose of RAASi in randomised patients avoiding hyperkalaemia, i.e. K+≤5.6 mmol/L. Patients will be allowed to continue with RAASi maximisation to K+<6.0mmol/L. Patients will be tested at baseline and follow-up visits for hyperkalaemia, AKI, symptomatic hypotension and QT prolongation on ECG. Results: The study results will show if SZC is superior to placebo for RAASi maximisation in CKD-HF patients while maintaining safe levels of serum potassium without any adverse impact on quality of life. The study will demonstrate if SZC allows higher RAASi dose and more dose escalations than placebo. It will also examine the impact of RAASi escalation on creatinine, proteinuria, and cardiac blood biomarkers. Conclusion: If positive, the results of this study will demonstrate that SZC enables RAASi up titration in CKD-HF patients, which potentially can help achieve optimal treatment and improve quality of life of the patient.

Cardiac resynchronization therapy (CRT) is an established pacemaker therapy for patients with symptomatic chronic heart failure, but is hampered by a non-response rate of 30-40%. Optimising left ventricular (LV) lead placement is the cornerstone of improving treatment. The optimal location for the lead is remote from scar but within segments demonstrating late electromechanical activation. The present study aims to investigate the efficacy and clinical effect of the use of real-time guided lead placement using cardiac MRI and fluoroscopy in a blinded, multicenter, randomized controlled trial.

Heart failure is the primary cause of morbidity and mortality worldwide. Currently drug treatments for heart failure manage the symptoms, but not restore the loss cardiomyocytes due to the very limited regenerative capability in the adult heart. Novel reparative therapies that replace the cardiomyocytes loss are highly demanded to restore the cardiac function. The main purposes of this explanatory study is to investigate the safety and efficacy of the catheter-based endocardial delivery of human iPSC-derived cardiomyocytes in patients with congestive heart failure.

This is a randomized, double-blind, placebo-controlled two-part study with a multiple escalating dose phase followed by a cohort expansion phase to assess safety, tolerability, pharmacokinetics and pharmacodynamics of AC01 in patients with heart failure with reduced ejection fraction (HFrEF).

FIRE-HFpEF is a multi-center, prospective, randomized, single-blinded, clinical feasibility study. This study will enroll up to 105 subjects with heart failure with preserved ejection fraction in the United States. Data will be collected to evaluate whether pacing therapies can lead to improvements in exercise capacity and health status of subjects.

Heart failure with preserved left ventricular ejection fraction (HFpEF) is a syndrome associated with high morbidity and mortality rates. Systemic low-grade inflammation is acknowledged to be a fundamental pathophysiological mechanism of HFpEF. Interventions targeting inflammatory pathway is understudied in HFpEF. Colchicine is a safe and well tolerated anti-inflammatory drug, which interferes with several steps in the inflammatory process. The drug has been extensively studied in different cardiovascular pathologies except HFpEF. We assume that colchicine decreases inflammation and reduces sST2 levels in HFpEF.

Results from recent clinical trials on bone marrow mononuclear cell (BM-MNC) transplantation show that this intervention can help reduce the incidence of heart failure (HF) after acute myocardial infarction (AMI). However, no study has evaluated the effect of the transplantation of mesenchymal stem cells (MSCs) on a clinical endpoint such as HF. This single-blinded, randomized, multicenter trial aims to establish whether the intracoronary infusion of umbilical cord-derived Wharton's jelly MSCs (WJ-MSCs) helps prevent HF development after AMI. The study will enroll 240 patients 3 to 7 days following an AMI treated with primary percutaenous coronary intervention (PPCI). Only patients aged below 65 years with impaired LV function (LVEF < 40%) will be included. They will be randomized to receive either a single intracoronary infusion of WJ-MSCs or standard care. The primary outcome of this study is the assessment of HF development during long-term follow-up (four years). Since the efficacy of MSCs is higher than BM-MNCs after AMI in the improvement of LVEF, it would be probable that these cells may have a better clinical effect as well. However, no study has evaluated the impact of the transplantation of MSCs on a clinical endpoint such as HF. This study will help determine whether or not the infusion of intracoronary WJ-MSCs in patients

This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of congestive heart failure and angina
