Heart Failure Clinical Trials

The purpose of this study is to investigate the potential recovery of heart function in end-stage heart failure patients supported with a Left Ventricular Assist Device (LVAD) through applying a myocardial conditioning protocol. During myocardial conditioning, LVAD speed is reduced gradually in order to increase the work load of the heart. Multiple previous studies have shown that interventions like this may improve heart function and give patients the opportunity for a better quality of life. Read Less

The goal of this clinical trial is to compare two types of exercise prescriptions in cardiac rehabilitation eligible older adults (60 years or older) with heart disease. The investigators found in a single site pilot trial (insert NCTxxx) that one exercise prescription was better and are now repeating this study in a larger population at two sites (Baystate Medical Center, Springfield MA and Henry Ford Health System, Detroit MI). The main questions the investigators aim to answer are: 1. Compare two different exercise prescriptions in cardiac rehabilitation on exercise outcomes 1. Graded exercise test +Target heart rate range prescription \[GXT-THRR\] 2. Rating of perceived exertion (RPE) 2. What is the role of psychological feedback on fitness outcomes during cardiac rehabilitation and physical activity outside of cardiac rehabilitation. 3. What are the long-term clinical outcomes between the two exercise prescriptions Participants will be asked to: * Complete surveys about physical activity, exercise anxiety, exercise efficacy, and fears about exercising * Perform fitness measures (6-minute walk test, balance tests, stand to sit tests, a 400 meter walk, and handgrip strength) * Attend at least 18 sessions of cardiac rehabilitation after they are randomized to their exercise prescription group * Wear a heart rate monitor and a physical activity monitor per study protocol Participants will be randomized (flip of a coin) to either receive a graded exercise test and psychoeducational feedback or lifestyle education (nutrition for cardiac). The graded exercise test will be used to create a personalized exercise prescription with the target heart rate range calculated from the test and the lifestyle education group will use their ratings of perceived exertion for their exercise prescription.

The goal of this study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3 Left Ventricular Assist System when used for the treatment of advanced, refractory, left ventricular heart failure. Read Less

The primary objective of this study is to learn whether a morning dose of extended-release torsemide enhances renal sodium excretion after lunch (4-8 hours after dosing) compared to immediate-release torsemide. This is a randomized, double-blind, crossover study in patients with heart failure who are on a stable dose of a loop diuretic. During the study period, participants' current loop diuretics will be replaced with an equivalent dose of either immediate-release or extended-release torsemide. Following a one-week stabilization period on the assigned torsemide formulation, patients will report to the clinical site for an assessment visit. On the study day, patients will take a single dose of the same torsemide formulation they have been on for the past week, administered after breakfast. Urine samples be collected are: * 0-4 hours post-dosing (pre-lunch period) * 4-8 hours post-dosing (post-lunch period) * 8-24 hours post-dosing (24 hours period) The primary endpoint will be urinary sodium excretion (4-8 hours after dosing). This will be compared between the extended-release arm and the immediate-release arm to assess the efficacy of prolonged diuretic action. In addition, urinary potassium and creatinine excretion and creatinine clearance will be measured in all urine samples as the safety endpoints. Read Less

The purpose of this early feasibility study is to evaluate the safety and feasibility of the device for percutaneous shunting of the interatrial septum and improvement of heart failure related symptoms. The primary goal is to determine if the device is safe to use. The findings from this study may be used to refine the intended patient population, the design of the device, or develop a subsequent randomized study. Read Less

The goal of this clinical trial is to learn which iron treatment works better for adults with congestive heart failure and low iron levels: intravenous (IV) iron given through a vein or oral (PO) iron taken by mouth. Participants must have heart failure with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF) and a transferrin-saturation (TSAT) level below 20 percent. The main questions the study will answer are: 1. Does IV iron raise walking distance on a 6-minute walk test more than oral iron after 24 weeks? 2. Does IV iron improve symptoms and quality of life more than oral iron? 3. How do the two treatments compare for safety, side effects, and hospital readmissions/ mortality? Researchers will compare IV ferric carboxymaltose with oral ferrous sulfate to see which option helps people feel and function better. What participants will do * Be randomly assigned by (like flipping a coin) to IV iron or oral iron. * Receive either a one-time IV iron infusion (with possible repeat at 12 weeks) or take iron pills twice each day for 24 weeks. * Visit the infusion clinic at 6 weeks for second dose of IV iron if needed. * Visit the clinic at 12 weeks for a follow-up to gather follow-up data including 1. A 6-minute walk test 2. Brief symptom and quality-of-life surveys 3. Blood tests to measure serum iron, ferritin, and transferrin saturation This study will help doctors decide whether IV or oral iron is the safer, more effective way to treat iron deficiency in people with heart failure in our local community.

The aim of this study is to learn about the safety of empagliflozin in dialysis patients as a preparation for a future large clinical trial. Empagliflozin has been approved by the Food and Drug Administration for the treatment of either type 2 diabetes, heart failure, or chronic kidney disease among patients not on dialysis. The use of empagliflozin has not been studied or approved among patients on dialysis for kidney failure because empagliflozin acts on the kidneys. However, recent experimental studies have indicated that empagliflozin may provide direct heart benefits. Some dialysis patients have substantial residual kidney function, which may be protected by empagliflozin. Participants will be given empagliflozin for three (3) months on top of the standard of care (usual medical care for participants' condition) and will be followed up until one (1) month after the last dose. The investigators will collect information about participants' general health, obtain blood, urine, and imaging studies, check home blood pressure, monitor home blood sugar levels, and ask health-related questions to assess the safety and potential benefits of empagliflozin over four (4) months, including one month before the three (3)-month empagliflozin treatment.

The purpose of this study is to determine the effects on heart failure signs and symptoms of the use of either ertugliflozin, metolazone or placebo, in conjunction with intravenous loop diuretic use in acute settings and chronic oral loop diuretic therapy. There are two general purposes for this study. The proposed study is both larger and more rigorous than essentially all PK/PD studies that form the basis of current practice with loop diuretics as well as all studies looking at add-on thiazide therapy (current guideline-recommended adjuvant). The second is to generate a mechanistic understanding of the pleotropic cardio-renal factors with chronic therapy that differentiate ertugliflozin from traditional diuretics particularly in how they maintain reduced blood volume without the complication of over-diuresis and volume depletion.
