Active clinical trials for "Heart Failure"

This is a retrospective chart review examining our experience with carvedilol in CHF secondary to left-to-right heart shunt lesions. The treatment group will be children who have received carvedilol. The control or comparison groups will be patients who have received either digoxin/furosemide or captopril for this indication. Charts will be reviewed of patients who have been treated at Children's Healthcare of Atlanta and as outpatients by Sibley Heart Center Cardiology between September 2000 and October 2005. Patients will have been started on carvedilol prior to April 1, 2005 and only information up to October 1, 2005 will be used for this study. We will review approximately 50 charts for this study. We will evaluate the effectiveness of these medications at reducing symptoms of CHF.

This study evaluates the addition of transcatheter mitral valve repair with the MitraClip device to medical treatment in patients with heart failure and moderate functional mitral regurgitation to determine the impact of left ventricular remodelling and patients' functional capacity.

Based on accumulating evidence showing that hypothyroid status is associated with poor prognosis among heart failure (HF) patients, the study is designed to evaluate whether replacement treatment with levothyroxine could have beneficial effects on patients with HF and subclinical hypothyroidism. The study is a prospective, randomized, parallel-group trial to assess the efficacy and safety of levothyroxine replacement on evidence-based HF standard therapy in stable chronic heart failure patients with subclinical hypothyroidism.

The Day-Care Unit for Patients With Refractory Heart Failure (DayCare-HF) is an observational study on selected patients with advanced refractory heart failure. The purpose of the study was to examine the comprehensive management of HF in the day-care unit in terms of the safety and its impact on the rehospitalization and mortality rates in patients with advanced refractory HF.

This is a prospective, randomised double blind, controlled, parallel-group phase I and II study. Its aim is to assess that a single intracoronary infusion of autologous bone marrow-mononuclear cells is safe and effective in hear failure patients with reduced left ventricular ejection fraction(<=30%) when compared to a control group of patients undergoing best medical care.

This study is a randomized controlled multicenter clinical trial, in which about 340 patients with newly diagnosed or prior diagnosed chronic heart will be recruited. Patients will be randomly divided into Angiotensin-Neprilysin Inhibition (ARNI) group and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) group. All-cause death, cardiac death and re-hospitalization due to heart failure will be evaluated in 1, 3, 6, 12 months after recruitment.

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).

LV pacing at various sites with recording of ECG and subsequent signal analysis at different sites.

Repetitive levosimendan infusions for patients with advanced chronic heart failure (LeoDOR) A randomised, double-blind, placebo-controlled multicentre study with parallel group design. Mortality and rehospitalisation rates are high in the vulnerable phase following heart failure hospitalisation. Previous studies suggest that these events can be reduced by repeat infusions of levosimendan in patients with advanced heart failure.

This protocol describes a 2-arm randomized controlled pilot study assessing the tolerance, safety and efficacy of sildenafil compared to control. The hypothesis is that sildenafil will be well tolerated and efficacious in patients with chronic heart failure (NYHA class II and III) with evidence of systolic dysfunction (EF ≤40 %) and secondary pulmonary hypertension (SPAP >40mmHg). Patients that satisfy the inclusion criteria will be randomized to sildenafil (40mg x 3) or placebo therapy for 6 months in a 2:1 blinded fashion. The placebo group will be compared to the active therapy group and analyzed for differences in the main study end-points Patient Global Assessment and 6-Minute Walk Test. The study will also assess safety, tolerability, symptoms and quality of life.
