The purpose of this study was to investigate the effects of initiation of sacubitril/valsartan vs enalapril treatment on objective measures of both waking activity and sleep in subjects with heart failure with reduced ejection fraction.
This study will provide insight into whether cardiac function changes with oral Ketone Esters (KE) administered to patients with Type 2 Diabetes Mellitus (T2DM) and Heart failure with reduced ejection fraction (HFrEF). Plasma ketones are avidly extracted by cardiac muscle and their uptake is not dependent upon insulin or influenced by insulin resistance.
The primary hypothesis is that patients with HFREF (heart failure with reduced ejection fraction) will demonstrate a markedly expanded intravascular volume which will correlate with elevated right heart hemodynamics and increased venous capacitance parameters, whereas patients with HFPEF(heart failure with preserved ejection fraction) will demonstrate euvolemia to mild volume expansion and a lack of correlation with hemodynamic and venous compliance parameters.
The purpose of this study is to assess the safety and tolerability of initiating LCZ696 in heart failure patients with reduced ejection fraction (HF-rEF) using conservative (reaching target dose over 6 weeks) and condensed (reaching target dose over 3 weeks) up-titration regimens.
Heart failure (HF) affects more than 6 million adults in the U.S. alone, with increasing prevalence. Cardiovascular congestion with resultant limitation in physical activity is the hallmark of chronic and decompensated HF. The current HF physiologic model suggests that congestion is the result of volume retention and, therefore, therapies (such as diuretics) have generally been targeted at volume overload. Yet therapeutic approaches to reduce congestion have failed to show significant benefit on clinical outcomes, potentially due to an untargeted approach of decongestive therapies. The investigators' preliminary work suggested a complimentary contribution of volume redistribution to the mechanism of cardiac decompensation. The investigators identified the splanchnic nerves as a potential therapeutic target and showed that short-term interruption of the splanchnic nerve signaling could have favorable effects on cardiovascular hemodynamics and symptoms. As part of the investigators' proposal, the investigators will test the safety and efficacy of prolonged splanchnic nerve block in a randomized, controlled, blinded study in patients with HF and reduced ejection fraction (HFrEF). The results will help test the hypothesis of volume redistribution as a driver of cardiovascular congestion and functional limitations and pave the way for splanchnic nerve blockade as a novel therapeutic approach to HF.
This is an observational study in which data already collected from people with chronic heart failure with reduced ejection fraction (HFrEF) are studied. In observational studies, only observations are made, without participants receiving any advice or any changes to healthcare. Chronic HFrEF is a long-term condition in which the heart becomes weak and cannot pump enough blood to the rest of the body with each heartbeat. This leads to a reduced supply of oxygen, which the body requires to function properly. The study treatment, vericiguat, works by increasing the activity of an enzyme called soluble guanylate cyclase (sGC), which relaxes the blood vessels and allows more blood to flow. As a result, the heart can pump better. It is already approved for doctors to prescribe to people with chronic HFrEF in the United States (US) who are stabilized after a recent "decompensation event". The treatment with vericiguat starts at a low dose, which should be increased gradually to the target dose based on how a patient tolerates the treatment. The participants in this study are already receiving treatment with vericiguat as part of their regular care from their doctors. The main purpose of the study is to learn more about the dosage pattern of vericiguat in people with chronic HFrEF in the US. To do this, researchers will collect the following information for 3 months after participants' first dose of vericiguat: * starting dose of vericiguat * daily changes in dosage pattern * time taken to reach the target dose * number and percentage of participants: * with specific changes in dosage pattern * reaching the target dose of vericiguat They will also collect information on how often low blood pressure or fainting occurs, which are well known events in people with chronic HFrEF. The data will come from the participants' information stored in a database called the HealthVerity HF dataset. Data collected will be from people with chronic HFrEF who started taking vericiguat between January 2021 and April 2023. Researchers will only look at the health records of participants in the US. Researchers will track participants' data and will collect information for a maximum of 6 months before and 3 months after their first dose of vericiguat. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.
The goal of this randomized clinical trial is to test the effect of patient education on extent of use of guideline directed medical treatment (GDMT) of heart failure with reduced ejection fraction. The main question that our study aims to answer is if patient education can improve the adherence to GDMT in heart failure with reduced ejection fraction. Participants will receive educations about GDMT benefits in 1,3 and 5 months after discharge from hospital.
Concentrated autologous bone marrow mononuclear cells (ABM MNC) contain potentially therapeutic cell factors and past studies support therapeutic benefit to patients with cardiac diseases of acute myocardial infarction, ischemia, and heart failure when utilized as this study is designed. The purpose of the study is to determine the safety and efficacy of CardiAMP cell therapy system in patients with ischemic heart failure. It is a prospective, multi-center, randomized, controlled, patient and evaluator-blinded study comparing treatment with the CardiAMP cell therapy system to a control procedure with diagnostic catheterization.
This study is researching an experimental drug called REGN5381 (called "study drug"). The study is focused on patients with heart failure with reduced ejection fraction (ie, the heart is not functioning as well as it should). The aim of the study is to see how safe, tolerable, and effective the study drug is. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects)
The purpose of this study is to evaluate the safety and effectiveness of tovinontrine compared to placebo to lower NT-proBNP in patients with chronic heart failure with reduced ejection fraction.
