Intravenous Iron Infusion With Ferric Carboxymaltose in Patients With Heart Failure and Iron Deficiency

Start date: June 1, 2019
Phase: Phase 3
Study type: Interventional

There are few studies on myocardial iron deficiency. In 2016, a study in Spain evaluated patients with heart failure (with or without anemia) and their response to intravenous iron infusion. These patients, initially with mean T2* values of 39.5 msec, were followed by Cardiac Magnetic Ressonance (CMR) before and after iron replacement with Ferric Carboxymaltose (Ferinject®) , obtaining at the end of the study, improvement in ventricular function and increase in the myocardial iron load (T2 * mean of 32 msec ). The aim of the present study was to evaluate the correlation between intravenous iron replacement and increased myocardial iron deposits and their effect on ventricular function. Because it is a pilot study with few data in the literature and based on the study that used a sample of 8 patients, it is planned to use an initial sample of 20 patients. In the CMR, the team intent to evaluate the global ventricular function, the iron load by the T2 * method, the cardiac strain, the "Fiddle" and the "Fat water" of each patient. After this examination, patients will undergo intravenous 1g of Ferric Carboxymaltose (Ferinject®). A comparative analysis of the ejection fraction values at the beginning and at the end of the study by CMR will be performed, in addition to a clinical reassessment, in which improvement of dyspnea and tiredness are expected. There will be laboratory reassessment of ferritin and transferrin saturation to monitor treatment. The inclusion criteria will be: Patients older than 18 years, with iron deficiency and reduced ejection fraction defined as: serum ferritin <100 μg / L or with ferritin 100-299 μg / L with transferrin saturation <20 %; Hemoglobin <12g / dL in women and <13g / dL in men; Clinical stability in the last 3 months; Left ventricular ejection fraction (LVEF) <40% assessed by transthoracic echocardiography or CMR in the last 3 months. The exclusion criteria will be: Patients younger than 18 years, Patients with preserved ejection fraction (> 50%), pregnant women, refusal to participate in the present study, implantable pacemaker or implantable defibrillator incompatible with MRI, cerebral cerebral aneurysm clip and/or intracerebral or intraocular metal fragments, electronic cochlear implants, patients with claustrophobia, patients with clinical or hemodynamic instability and patients with indication for blood transfusion (Hb ≤ 7g / dL).

NCT ID: NCT03836482 Not yet recruiting - Clinical trials for Cardiorenal Syndrome

Selective Cytopheretic Device (SCD) Trial

Start date: February 15, 2019
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the selective cytopheretic device on the immune dysregulated state of congestive heart failure(CHF) with CRS and to assess the benefit of the device to improve cardiovascular and renal function. The study will enroll eligible patients in the ICU with acute on chronic systolic heart failure and worsening renal function due to cardiorenal syndrome while awaiting LVAD implantation. In this study patients who are eligible and agree to participate will receive treatment with the SCD. The treatment will be for 6 hours a day up to 6 days. Additionally, participants will have additional study procedures and be evaluated to determine if their kidney function improves enough to undergo LVAD implantation.

SyncAV Study: Investigation of the Efficacy of the SyncAV Fusion Pacing Algorithm on Exercise

Start date: January 2019
Phase: N/A
Study type: Interventional

In patients with weak pumping function of the heart, uncoordinated contraction of the chambers can be corrected using a cardiac resynchronization therapy (CRT) pacemaker. These devices make patients live longer by improving how the heart pumps and reducing symptoms such as breathlessness. However, not all patients benefit from CRT and programming devices optimally can greatly influence success. Predicting the correct timings of contraction between the atria (top chambers of the heart) and the ventricles (bottom chambers), as well as between the left and right ventricles, especially when heart rate increases during exercises, is challenging. A new approach to optimizing CRT programming has been proposed known as 'fusion-pacing'. This allows the electrical wave from the heart's own conduction system to merge or fuse with the impulse from the pacemaker in the left ventricle. The timing of the pacemaker's impulse is continuously adjusted to measurements the device makes of the hearts natural conduction. What is not clear is how effective 'fusion-pacing' is during exercise when the hearts natural conduction changes rapidly and unpredictably. We plan to investigate this by monitoring the electrocardiogram (ECG) whilst accurately measuring exercise performance and ability during a cardiopulmonary exercise test (CPET) on an exercise bike. We will also ask participants to rate their perceived exercise intensity to see whether fusion pacing improves ECG resynchronization, exercise performance, and patients' symptoms compared to standard programming.

NCT ID: NCT03764722 Recruiting - Clinical trials for Systolic Heart Failure

Effectiveness of a Repetitive Use of 24-hour Levosimendan Infusions in Patients With Severe Systolic Heart Failure in Order to Prevent Rehospitalizations

Start date: August 1, 2018
Phase: Phase 4
Study type: Interventional

Rehospitalizations due to exacerbation of chronic heart failure are an important problem for patients suffering from heart failure. Rehospitalzations lead to worse prognosis, have an impact on the quality of life and have a negative financial impact on the health care system. Currently, studies are being conducted on the efficacy of levosimendan in the prevention of heart failure exacerbations. Patients receive levosimendan at repetitive use and preliminary results suggest a reduction in the incidence of exacerbations of heart failure. Thanks to the clinical trial planned in the Department of Cardiology of the Biziel Hospital with repeatable use of levosimendan, it is possible to determine the benefits of this method of treatment more accurately.

Can COGNItive Function be Improved by Cardiac Resynchronisation Therapy?

Start date: April 2019
Study type: Observational

The primary objective of COGNI-CRT is to assess whether Cardiac Resynchronisation Therapy (CRT) can improve cognitive function in patients with systolic HF (LVEF ≤35%), when compared to a control group of patients implanted with an Implantable Cardioverter-Defibrillator (ICD) or a permanent pacemaker (PPM) with systolic HF (LVEF ≤35%). This clinical investigation is a prospective, single-centre cohort study. Each participant will be followed for 6 months. The study will collect data over 3 years; 2.5 years for enrolment and 6 months until the last participant completes the last 6-month follow-up visit. N.B: COGNI-CRT does NOT affect the patient's care pathway - the patients who will be selected for participation are those who have already been referred for the device implant. The ONLY difference to the patient's care pathway caused by COGNI-CRT is the addition of a battery of cognitive function tests, which involves asking the patient questions and asking them to complete questionnaire-like cognitive tests. NTpro-BNP levels, NYHA classification and LVEF will be measured prior to device implantation and at 6-months post-implant to assess the device's impact on the participant's heart failure (and CRT response). N.B: NT-proBNP, NYHA classification and LVEF are all parts of the patient's standard care pathway, COGNI-CRT is just utilising the data collected as part of the investigation. The main study arm and control group allows COGNI-CRT to assess 3 potential outcomes for patients with severe HF (LVEF <35%): 1. Cognitive function is not improved by CRT, ICDs or PPMs 2. Cognitive function can be improved by the assurance of rate control offered by CRT, ICDs and PPMs 3. Cognitive function can be improved by the assurance of ventricular synchronisation and rate control provided by the additional left ventricular lead in CRT devices.

NCT ID: NCT03677271 Completed - Clinical trials for Heart Failure, Systolic

A Novel Home-based Physical Activity Intervention for Stable Chronic Heart Failure Patients

Start date: December 16, 2015
Phase: N/A
Study type: Interventional

The project focuses on heart failure (HF), a complex clinical syndrome of symptoms and signs that suggest the efficiency of the heart as a pump is impaired. Around 950,000 people in the UK have HF. Both the incidence and prevalence of heart failure increase steeply as a result of an ageing population, improved survival of people with ischaemic heart disease and more effective treatments for heart failure. Aside from the obvious individual burden HF also accounts for 1 million inpatient bed days - 2% of all NHS inpatient bed days and 5% of all emergency medical admissions to hospital which are projected to rise by 50% over the next 25 years. There is a pressing need to explore effective ways to manage the individual and societal burden of HF. Despite exercise being an effective, safe, and a recommended (class I) therapy for people with heart failure according to clinical guidelines from the UK, EU, and USA, it is currently out of reach for majority people with HF. This project addresses this directly by designing and evaluating an exercise therapy that will be available to those living with HF with potential to improve their symptoms, function and quality of life

Reprogramming to Prevent Progressive Pacemaker-induced Remodelling

Start date: August 1, 2017
Phase: N/A
Study type: Interventional

The aim is to provide evidence of the long-term benefits of personalised pacemaker programming on heart function and battery longevity. This will be achieved by showing in a single centre, phase II, double-blind, randomised, placebo-controlled trial that reducing the amount of pacemaker beats to a minimum reverses these changes and extends battery life.
