We believe that blocking of the Greater Splanchnic Nerve (GSN) will stop Sympathetic Nervous System (SNS) activity from reaching the splanchnic vessels and result in a redistribution of blood volume back into the splanchnic reservoir, which will result in reduction of central venous, pulmonary and right and left heart pressures. For patients having Heart Failure With Preserved Ejection Fraction (HFpEF) we expect these changes to improve dyspnea and capacity to exercise, improve quality of life, increased diuretic responsiveness, Furthermore, the expected benefits of unloading the central venous and arterial system through GSN ablation should improve hemodynamic control and lessen the incidence and severity of acute decompensations leading to reduced re-hospitalizations and associated healthcare costs. This has the potential for significant social and healthcare impact.
This is an international, multicentre, parallel-group, event-driven, randomised, double-blind, placebo-controlled study in HFpEF patients, evaluating the effect of dapagliflozin 10 mg versus placebo, given once daily in addition to background regional standard of care therapy, including treatments to control co-morbidities, in reducing the composite of CV death or heart failure events.
Heart failure (HF) accounts for 2% of National Health Service (NHS) expenditure, and 5% of emergency hospitalisations. Patients with HF with preserved ejection fraction (HFpEF) are older, have more comorbidities, have similarly poor or worse outcomes compared to patients with reduced ejection fraction (HFrEF), and currently lack an evidence base for treatment. The investigators hypothesise that outcomes of patients with HFpEF can be improved through optimised management and self-management of comorbidities, fluid status and lifestyle delivered in primary care in collaboration with specialists. The primary aim is to develop a programme of optimised management by improving understanding of needs and experiences of patients with HFpEF, clinical decision-making and management in primary care, and integrating research findings with patient and clinical expertise. The main objective for this work package is to identify patients with HFpEF in primary care and assess comorbidities and other factors, management, morbidity and mortality at one year. The methodology employed will be a longitudinal cohort study of 270 patients with HFpEF in primary care followed for 12 months.
Patients with unexplained stress dyspnea ( ≥ stage 2 NYHA), no significant underlying lung disease, with an ejection fraction > 50%, normal resting filling pressures, NTproBNP < 220 pg/ml in < 75 years, and < 450 pg/ml in ≥ 75 years will be studied with stress echocardiography and cardiometabolic stress test (VO2). These patients may have abnormal adaptation during exercise, suggesting that chronic symptoms may be related to a heart failure with preserved ejection fraction (HFPEF). More accurate and earlier diagnosis of HFPEF using stress echocardiography and VO2 may better manage stress dyspnea in patients and prevent progression of HFPEF. A clinical assessment will be offered to people with unexplained stress dyspnea. The procedures and products used in this study are usually used as part of HFpEF's diagnostic strategy. During this assessment, carried out on an outpatient basis, an anamnesis collection, a cardiovascular clinical examination, an evaluation of dyspnea by the NYHA functional class and by 2 questionnaires, an electrocardiogram will be carried out, a 6-minute walk test, a biological blood test, a trans thoracic rest and stress cardiac ultrasound, respiratory functional tests (with diffusion capacity of lung for carbon monoxide (DLCO) and blood gas), and a metabolic stress test. A follow-up at 1 and 2 years is planned (visit, sampling and resting echocardiography).
To determine biomarker responses to Entresto™in patients with Heart Failure with preserved Ejection Fraction (HFpEF) and who have high or low serum neprilysin (NEP) levels.
To estimate the prevalence of transthyretin cardiac amyloidosis (TTR-CA) among Heart Failure with Preserved Ejection Fraction (HFpEF) patients with increased LV wall thickness in Southeast Minnesota using 99mTc-PYP single-photon positive emission computed tomography with computed tomography (SPECT/CT).
This retrospective observation is to investigate the incidence,clinical outcomes and prognosis of hospitalized heart failure with preserved ejection fraction (HFpEF) in patients with acute myocardial infarction(AMI).
Heart failure is a clinical syndrome marked by breathlessness, even at low levels of exertion, general fatigue, and fluid retention and is estimated to affect 5.1 million people in the United States. Heart failure with preserved ejection fraction (HFpEF) means that the heart pumps enough blood to the body, but patients still have terrible symptoms. It is estimated to account for about 50% of all heart failure cases. Experts agree that impaired filling of the heart, perhaps due to "stiffness" of the heart muscle itself, critically underlies HFpEF. There is currently no clinical technique for measuring heart muscle (myocardial) stiffness; the very definition of "myocardial stiffness" remains poorly established. Consequently, the ability to study the mechanisms that underlie HFpEF is virtually non-existent, and limited treatment options will persist without significant advances. The objective of this project is to use an Equilibrium-Material-Stability (EMS) framework that couples patient-specific clinical MRI and heart pressure data in a computational model of the heart to diagnose changes in myocardial stiffness. The central hypothesis is that the new EMS framework for understanding the mechanisms of diastolic dysfunction in HFpEF will be more sensitive and outperform currently available approaches.
The objective of the CAPACITY-HFpEF study is to evaluate the safety and efficacy of IW-1973 compared with placebo when administered daily for approximately 12 weeks to patients with HFpEF. The study will evaluate the effect of oral IW-1973 on peak exercise capacity in patients with HFpEF, with or without permanent or persistent atrial fibrillation.
This study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).
