Metformin in Heart Failure Without Diabetes
Heart FailureColumbia University Medical Center is conducting a pilot clinical research study that will assess the use of the medication metformin for heart failure in patients who are not diabetic and have no evidence of insulin resistance. Patients will received either the study drug metformin or placebo for 4 months. During the study, the patients will undergo extensive testing that will include symptom assesment, exercise capacity, echocardiography, cardiac PET imaging and blood tests.
The Impact of Magnesium on Exercise Tolerance, Quality of Life and Clinical Outcomes in Chronic...
Magnesium DeficiencyHeart FailureMagnesium supplementation could improve cardiac performance. Patients with chronic heart failure (CHF) are magnesium deficient and we hypothesized that 1 year supplementation of oral magnesium comparted to placebo will improve exercise duration time and quality of life.
SyncAV Post-Market Trial
Congestive Heart FailureThe SyncAV Post-Market Trial is a prospective, randomized, multi-center trial performed to determine if cardiac resynchronization therapy (CRT) devices programmed with SyncAV ON improve long-term CRT response compared to devices programmed with conventional CRT through evaluation of changes in left ventricular (LV) reverse remodeling.
Safety and Efficacy of Induced Pluripotent Stem Cell-derived Engineered Human Myocardium as Biological...
Heart FailureThe BioVAT-HF trial will test the hypothesis that cardiomyocyte implantation via engineered heart muscle (EHM), the proposed investigational medicinal product (IMP; designated "Biological Ventricular Assist Tissue" or BioVAT), results in sustainable remuscularization and biological enhancement of myocardial performance in the failing heart. EHM are constructed from defined mixtures of induced pluripotent stem cell (iPSC)-derived cardiomyocytes and stromal cells in a bovine collagen type I hydrogel. Comprehensive preclinical testing confirmed the rationale for the clinical translation of the myocardial remuscularization strategy by EHM implantation. The patient target population for EHM therapy is patients suffering from advanced heart failure with reduced ejection fraction (HFrEF; EF: ≤35%) and no realistic option for heart transplantation.
Above-Knee-High Application of Lower Limb Compression and Its Impact on Clinical Outcome in Patients...
Heart Failure; With DecompensationLower Extremity Edema1 moreHeart failure (HF) remains one of the most common causes of hospitalization with high morbidity and mortality, and its worldwide prevalence is increasing. Despite notable progress in outcomes for HF the rate of early rehospitalization for HF (re-HHF) remains high, especially in the first 30 days. The rate of 30-day HF rehospitalization in the claims databases of the USA and in worldwide randomized clinical trials is 20-25% and 5-10% respectively. In patients with bilateral leg edema, the presence of CHF (congestive heart failure) as the factor causing or worsening local leg swelling should be evaluated. Application of local leg compression can be considered in stable CHF patients without decompensated heart function (NYHA Class I and II) for both CHF-related edema treatment and for treatment of concomitant diseases leading to leg swelling occurrence. Current literature does not have recommendations on the routine use of lower limb compression in leg swelling related to end stage heart disease and advanced, decompensated heart failure. Potential benefits of applying medical compression in more severe classes of CHF (NYHA Class III and IV) would need to be evaluated by further randomized clinical studies to determine which cohort of patients would benefit most from lower limb compression, as well as to choose the safest and most efficient compression protocol for these patients. The AIM of this study is to improve the clinical outcome of patients admitted with exacerbation of heart failure with associated volume overload. The primary objectives are: 1) diminish the duration of hospitalization of CHF patients; 2) decrease the incidence of rehospitalization from CHF exacerbation and 3) prevent local complications associated with prolonged lower extremity edema. The investigators hypothesize that the application of local compression to bilateral lower extremities, when added to guideline-based therapy for CHF exacerbation, will improve overall clinical outcome in patients at the University of Texas Medical Branch (UTMB). If our intervention is proven to be beneficial, it could lead to a significant reduction in nationwide hospitalization costs associated with heart failure.
Percutaneous Coronary RevascularizatiOn VERsus Coronary-Artery Bypass Grafting for Multivessel Disease...
Heart FailureRevascularizationA short description, 5000 characters Ischemic cardiomyopathy related to coronary artery disease is currently the leading cause of heart failure. When it is responsible for heart failure, the coronary artery disease likely involves 2 or 3 vessels. Percutaneous coronary angioplasty, which is the other available technique for coronary revascularization, has never been evaluated in this indication. The results of retrospective registries studying the strategy for multivessel revascularization in patients with heart failure are inconsistent and no randomized study has been performed so far. Currently, ESC guidelines recommends to perform coronary-artery bypass grafting (IB) or percutaneous coronary intervention (IIa C) with the acknowledgement that percutaneous coronary intervention has never been properly evaluated in this setting. However, it has been previously demonstrated that left ventricle dysfunction significantly increases mortality and morbidity during and after cardiac surgery (3-10% mortality when LVEF is ≤30%). Moreover, the technical progresses in stent development and manufacturing have led to a dramatic decrease in the incidence of stent thrombosis and in-stent restenosis. Therefore, we hypothesize that percutaneous coronary angioplasty may be an attractive strategy for revascularization in patients with multi-vessel disease and left ventricle dysfunction, who are at high risk of surgical complication. Thus, we aim to test the hypothesis that percutaneous coronary intervention is non-inferior to coronary-artery bypass grafting for revascularization in patients with multivessel disease and left ventricle dysfunction. The main objective is to demonstrate that percutaneous coronary angioplasty is non-inferior to coronary-artery bypass grafting for multivessel revascularization in patients with left ventricular dysfunction on major cardiac and cerebrovascular events (MACCE). Method:A Prospective Randomized Open label, Blinded Endpoint, parallel-group, active controlled, non-inferiority, multicenter trial.
High Calorie High Protein Nutrition Supplementation in Advanced Heart Failure
Heart FailureIn this study, the investigators will determine the impact of a high calorie and high protein nutrition supplementation strategy on quality of life in participants with advanced heart failure. The investigators hypothesize that participants with advanced heart failure who receive the high calorie high protein nutrition supplementation strategy will experience an improvement in quality of life compared to those patients that receive usual care.
Neuromuscular Fatigue During Exercise in COPD-HF Overlap
Pulmonary DiseaseChronic Obstructive1 moreRationale. Chronic obstructive pulmonary disease (COPD) and heart failure (HF) coexist in approximately one third of patients presenting with one of these conditions. From a clinical standpoint, impaired tissue oxygen (O2) delivery stands as a common pathological mechanism of these cardiorespiratory diseases. Recent evidence suggest that muscle and cerebral blood flow and oxygenation are further impaired during exercise in patients with COPD-HF overlap compared to isolated diseases. However, it remains unknown whether impaired O2 delivery is associated with exaggerated manifestations of peripheral and central fatigue in COPD-HF overlap. In addition, improving cardiopulmonary interactions through non invasive positive pressure ventilation or through the addition of a hyperoxic gas mixture during exercise have been associated with enhanced cerebral and muscle O2 delivery and oxygenation in patients with COPD or HF. It is, therefore, conceivable that improved O2 delivery to these structures have beneficial influence on exercise capacity in patients with COPD-HF overlap due to less peripheral and central fatigue. Aims. To investigate the influence of impaired O2 delivery during exercise, and its alleviation with different interventions (non invasive positive pressure ventilation ± hyperoxia), on neuromuscular fatigue in patients with COPD-HF.
