NCT ID: NCT03936608 Recruiting - Clinical trials for Systolic Heart Failure

ECG for Programming in CRT

Start date: April 22, 2019
Phase: N/A
Study type: Interventional

Patients with heart failure and left bundle branch block benefit from Cardiac Resynchronization Therapy (CRT) that delivers pacing from right ventricle (RV) and left ventricle (LV) synchronously, resulting in electrical ventricular resynchrony followed by revere structural cardiac remodeling and thereby reduced heart failure symptoms, hospitalizations and death. It is not known if programming an individually optimized RV-LV pacing offset to maximize electrical resynchrony can improve benefit from CRT. The proposed study is a randomized controlled trial in patients undergoing implant of a CRT pacemaker/defibrillator device for clinical indications to evaluate benefit of RV-LV offset programming using electrocardiogram (ECG) vs. standard nominal CRT programming without RV-LV offset. Patients receiving CRT devices will be randomized to either (A) active intervention of programming RV-LV pacing offset to optimize ECG or to (B) active control of nominally programming CRT device without RV- LV offset. The patients will be followed to evaluate change in echocardiogram, quality of life, functional evaluation and a blood marker for heart failure.

Ferric Carboximaltose on Intra-myocardial Iron Load in Patients With Heart Failure

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

In general, anemia is associated with a greater presence of HF symptoms, worsening NYHA functional class, higher rate of hospitalization for heart failure, and reduced survival. However, it is unclear whether anemia is the cause of decreased survival or a marker for more advanced disease. Correction of iron deficiency in patients with New York Heart Association (NYHA) class II or III HF using intravenous iron (Ferinject®) improved "overall patient self-assessment" and NYHA functional class of 6-minute walk and health-related quality of life) in the FAIR-HF trial. It is unknown if iron deficiency is correlated with intra-myocardial iron load as assessed by cardiac magnetic resonance (CMR) and if the treatment with intravenous iron has any impact on intra-myocardial iron load and left ventricular function. The aim of the present study is to evaluate the effect of intravenous iron replacement on intra-myocardial iron deposits and the effect on left ventricular function. Because it is a pilot study with few data in the literature, it is planned to use an initial sample of 20 patients. We aim 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 by CMR. After this examination, patients will undergo intravenous infusion of 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. 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 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: May 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: June 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.
