Impact of Empagliflozin on Functional Capacity in Heart Failure With Preserved Ejection Fraction...

Heart Failure With Preserved Ejection FractionHeart Failure2 more

Sodium-Glucose Cotransporter-2 (SGLT-2) inhibitors generally and empagliflozin specifically have shown cardiovascular benefits in patients with heart failure (HF), but the underlying mechanisms remain unclear. Empagliflozin use resulted in lower pulmonary artery diastolic pressures in patients with HF, suggesting a beneficial diuretic effect. Other potential mechanisms include increased blood volume, decreased blood pressure, and changes in sympathetic and neuro-hormonal activation. This study is a single-arm, open label, prospective interventional study of 8 subjects with heart failure with preserved ejection fraction (HFpEF). Before and after 12 weeks of daily empagliflozin, participants with undergo comprehensive invasive exercise testing with a right heart catheter. Our goal is to evaluate the effects of empagliflozin on fitness, assessed by peak VO2, and peak left ventricular filling pressure, assessed by pulmonary capillary pressure at peak exercise.

A Randomised, Controlled Trial of a Low-energy Diet for Improving Functional Status in Heart Failure...

Heart Failure With Preserved Ejection FractionHeart Failure5 more

Heart failure with preserved ejection fraction (HFpEF) is a common and serious complication of obesity and type 2 diabetes (T2D). HFpEF occurs when the heart muscle unable to relax efficiently to pump the blood around the body. This leads to fluid build-up, breathlessness and inability to tolerate physical exertion. People who develop HFpEF do less well because treatment options are limited. Pilot data in patients with obesity and diabetes and a small number of patients with HFpEF have shown improvements in exercise capacity and reversal of changes in the heart and blood vessels. This study will assess if this is achievable in a multi-ethnic cohort of patients with established HFpEF. A total of 102 adults will be invited and allocate by chance into two groups: either a 12-week diet or health advice on how to lose weight. The study will determine if weight loss over 12 weeks can improve heart function, symptoms and ability to exercise. Additionally, participants' views on changing their diet and how this has impacted their symptoms will be sought during the study in an optional interview. This will help guide treatments planning in the future to get maximum benefits, and to individualize support to patients from different cultural backgrounds.

CORolla® TAA for Heart Failure With Preserved Ejection Fraction (HFpEF) and Diastolic Dysfunction...

Diastolic Heart FailureDiastolic Dysfunction

The study objective is to demonstrate safety and feasibility of the CORolla® TAA during 12 months of follow up, and to evaluate the performance of the therapy in relieving symptoms and restore diastolic function in patients with heart failure and preserved ejection fraction.

Parasympathetic Augmentation Via Respiratory Training for Patients With Systolic Heart Failure

Diastolic Heart Failure

This is a prospective, randomized, controlled clinical trial in which participants with NYHA class II or III and symptomatic Heart Failure with reduced Ejection Fraction (HFrEF) (Ejection Fraction (EF) ≤ 45%) will be assigned to one of two treatment groups: standard of care or breathing therapy.

Personalized Atrial Septostomy for Heart Failure

Heart FailureHeart Failure1 more

This study aims to investigate the safety and efficacy of personalized atrial septostomy (PAS) with combined use of radiofrequency-ablation and balloon-dilation (CURB) in heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF).

Noninvasive Elastography Evaluation of Myocardial Stiffness in Elderly Patients With Isolated Diastolic...

Cardiovascular Diseases in Old Age

The new approach propose in this protocol is based on ultrafast ultrasound and remote palpation of tissue by ultrasonic radiation pressure. Ultrafast ultrasound of biological tissues is based on an innovative ultrasound imaging approach that can image very fast soft tissue events at a rate of several thousands of frames per second and provide quantitative mapping of the elasticity of the tissues. This current project aims is to focus on myocardial rigidity in diastole to better assess the function of the heart failure.

Pilot Study Lp299v Supplementation in Chronic Heart Failure

Heart FailureHeart Failure With Reduced Ejection Fraction5 more

The goal of this study is to determine the impact of 12 weeks of Lp299v supplementation (20 million cfu/day vs. placebo) on exercise capacity, circulating biomarkers of cardiac remodeling, quality of life, and vascular endothelial function in humans with heart failure and reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) who have evidence of residual inflammation based on an elevated C-reactive protein level. This will be done in the setting of a randomized, double-blind, placebo-controlled trial.

A Preliminary Study for INFORMED

Heart FailureHeart Failure4 more

Investigators will determine whether N-of-1 trials, as a pragmatic, patient-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased subject confidence regarding the decision to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).

External Body Pressure in Heart Failure With Preserved Ejection Fraction

Heart FailureDiastolic

The primary objective of the study is to test the impact of positive and negative body pressure on exercise capacity, symptoms, blood volume distribution and central cardiac hemodynamics in patients with heart failure and preserved ejection fraction. Aim 1 will study healthy volunteers and heart failure patients non invasively while Aim 2 will study heart failure patients invasively (intracardiac pressures).
