Active clinical trials for "Heart Failure"

Heart transplantation is a life saving therapy for people with end stage heart failure. Acute rejection, a process where the immune system recognizes the transplanted heart as foreign and mounts a response against it, remains a clinical problem despite improvements in immunosuppressive drugs. Acute rejection occurs in 20-30% of patients within the first 3 months post-transplant, and is currently detected by highly invasive heart tissue biopsies that happen 12-15 times in the first year post-transplant. Replacing the biopsy with a simple blood test is of utmost value to patients and will reduce healthcare costs. The goal of our project is to develop a new blood test to monitor heart transplant rejection. Advances in biotechnology have enabled simultaneous measurement of many molecules (e.g., proteins, nucleic acids) in blood, driving the development of new diagnostics. Our team is a leader in using computational tools to combine information from numerous biological molecules and clinical data to generate "biomarker panels" that are more powerful than existing diagnostic tests. Our sophisticated analytic methods has recently derived HEARTBiT, a promising test of acute rejection comprising 9 RNA biomarkers, from the measurement of 30,000 blood molecules in 150 Canadian heart transplant patients. Our objective is to study a custom-built HEARTBiT test in a setting and on a technology that enable clinical adoption. We will evaluate the new test on 400 new patients from 5 North American transplant centres. We will also track patients' HEARTBiT scores over time to help predict future rejection, and explore use of proteins and micoRNAs to improve HEARTBiT. Our work will provide the basis for a future clinical trial. The significance of this work rests in that it will provide a tool to identify acute cardiac rejection in a fast, accurate, cost-effective and minimally invasive manner, allowing for facile long-term monitoring and therapy tailoring for heart transplant patients.

A prospective, multi-national, open-label clinical study which is conducted to asses the safety, feasibility and performance of the TRVD™ System in hospital-admitted patients with Acute Decompensated Heart Failure (ADHF) and evidence of reduced left ventricular ejection fraction. The study will include patients who present with significant venous congestion, as evidenced by clinical, laboratory and imaging signs of fluid retention. Study participation, for each enrolled subject, will last approximately 3 months post index procedure. Patients will be evaluated from enrollment until hospital discharge, then at 30, 60, and 90 days post procedure.

In this study the investigators are aiming to treat patients with acute heart failure with or without diabetes with Empagliflozin or placebo. Given the beneficial effects of Empagliflozin on heart failure hospitalization in the EMPA-REG OUTCOME trial, the investigators do expect a similar beneficial effect to be present in patients with acute heart failure. Acute heart failure is a state of hydropic decompensation resulting in dyspnea and congestions, caused by different etiologies of cardiac disease. Recompensation is reached by application of diuretic drugs and fluid restriction.

The purpose of this trial is to evaluate the long-term effects of Nocturnal Oxygen Therapy (NOXT) on the mortality and morbidity of patients with stable heart failure and a reduced ejection fraction (HFrEF), already receiving optimal guideline-directed medical therapy (GDMT), who have central sleep apnea (CSA).

This is a open-label, uncontrolled, monocenter, phase IV study. The aim of this study is to detect AEs or SAEs with a relative frequency of at least 11.5% in LVAD patients with iron deficiency anemia treated with oral ferric maltol for 12 weeks.

The purpose of this study is to evaluate the safety, pharmacokinetics, and effect on cardiac function of intravenous APD418 in adult participants with heart failure with reduced ejection fraction (HFrEF).

Acute heart failure (HF) is a common complication of acute coronary syndrome (ACS) associated with poor prognosis. Diagnosis of congestive HF in patients with initial, non-severe symptoms and signs may be challenging and early stages of this complication may be missed. To assess severity of HF in patients with ACS Killip classification is widely used but it does not take into account mild manifestations of HF. Thus, patients without rales in the lungs and/or S3 will be labelled as Killip class 1. The aim of this study is to determine the frequency, risk factors, abilities for early diagnosis using routine medical evaluation and clinical significance of subclinical and mildly symptomatic congestive HF in patients with ACS without persistent ST-segment elevation (NSTEACS). The study will include 200 patients with NSTEACS without history of severe HF and overt signs of congestion at presentation. Presence and severity of dyspnea (according to Likert ans Visual analog scales), physical signs of heart failure (respiratory rate, distention of jugular veins, S3), peripheral oxygen saturation by pulse oximetry, heart rate and signs of ischemia on ECG, signs of congestion according to lung and vena cava inferior ultrasound and chest X-Ray/CT as well as levels of NT-proBNP, hsTn, CRP and FABP at presentation will be evaluated. Presence and severity of dyspnea, physical signs of heart failure, oxygen saturation, heart rate and signs of ischemia on ECG, lung and vena cava inferior ultrasound will be re-assessed after 6, 12 and 24 hours. During hospitalization occurrence or worsening of clinical HF. Clinical events will be followed up to 12 months after hospitalization.

The present study includes patients with tricuspid regurgitation and heart failure diagnosed with echocardiography. The aim is to evaluate the physical performance of patients with tricuspid regurgitation and heart failure, to observe the course of the diseases and to allow a better understanding of new therapy options.

In a prospective observational cohort study (n = 100), the investigators aim to assess the correlation between cardiac biomarkers, advanced echocardiography and cystic fibrosis genotype and severity and determine whether these are prognostic markers of heart disease in patients suffering from cystic fibrosis (CF).

The purpose of this research study is to investigate the role of chemical reactions, such as inflammation and oxidation, in the cause of cardiac dysfunction (the heart does not function properly). The investigators are interested in studying the various chemical pathways for cell damage to determine which are the most prevalent and/or most important. The investigators also want to determine whether waste products of oxidative damage or other chemicals can be monitored in the blood or urine and serve as an indication of the existence and severity of overall heart disease activity. The investigators further want to determine whether certain proteins, called enzymes, affect this cell damage, or whether the presence or absence of certain genes which create different forms of these enzymes correlate with the development of heart failure or cardiomyopathy (weakening of the heart muscle or a change in heart muscle structure) or other cardiovascular diseases.
