The implementation of new medical therapies and guidelines, is a long and complex process that takes up to 10 years on average. This prolonged process is a global challenge and is mainly due to the complexity of cross-institutional patient care, involving primary care, out-patient clinics, nursing homes and patient associations. The main objective of this clinical trial is to determine whether a new digital strategy that employs official digital letters to inform and invite patients to evaluate their eligibility for new therapies, specifically the sodium-glucose co-transporter-2 (SGLT-2) inhibitor for heart failure patients, can facilitate and optimise the implementation. The aim is to increase the number of eligible patients with heart failure who start taking SGLT-2 inhibitors and reduce the time it takes to initiate treatment compared to the current process. Ultimately, this approach may improve patient outcomes.
The goal of this cross-sectional study is to investigate the prevalence of sarcopenia in patients with Heart Failure. The main question it aims to answer is: Whether there is a difference in the prevalence of sarcopenia across the spectrum of HFpEF (Heart failure with preserved ejection fraction) and HFrEF (heart failure with reduced ejection fraction). This is an observational study. The participant population involves patients with heart failure with preserved ejection fraction and heart failure with reduced ejection fraction. Healthy volunteers will be recruited as controls in addition to adults with asymptomatic Type 2 Diabetes. Participants will undergo the following: 1. Skeletal muscle mass, quality and body composition assessments using magnetic resonance imaging (MRI) and bioelectrical impedance analysis (BIA) 2. Skeletal muscle strength assessments (Dynamometer, FysioMeter, handgrip strength) 3. Skeletal muscle energetics assessment (31p-Spectroscopy pre/post-exercise recovery) Researchers will compare Heart failure groups with healthy controls and adults with asymptomatic type 2 Diabetes to see if there are significant differences in the strength, mass and quality of skeletal muscle.
African American adults in the United States have the highest prevalence rate of high blood pressure (hypertension) and heart failure in the world. African Americans with treatment resistant hypertension have higher levels of the enzyme - xanthine oxidase compared to Caucasians. This trial will test if administration of the xanthine oxidase inhibitor - Allopurinol (commonly used in the treatment of gout), given over a period of 8 weeks, will improve heart function, exercise ability and quality of life in African American Veterans with resistant hypertension.
The purpose of this registry is to evaluate the safety and effectiveness of LBBA pacing/sensing in patients already implanted with the Tendril STS 2088 lead.
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.
The goal of this observational study is to learn about SGLT2 inhibition medications in patients with symptomatic heart failure who are clinically prescribed FDA-approved SGLT2 inhibitors. The main question it aims to answer is: - What are the impacts of SGLT2 inhibition on systemic metabolomic and proteomic profiles? Participants will be asked to do the following before and after being prescribed a SGLT2i. - Six-minute walk testd - Calf MRI with plantar flexion exercise - Blood sample collection
Objective: to evaluate the possibilities and effect of telemedicine monitoring and management of patients with CHF (compared to patients with CHF without intensive telemedicine monitoring) on quality of life, prognosis and the presence of complications and hospitalisations. Patients with a stable form of congestive heart failure will be gradually included in the study. Half of them will be defined by random selection to intervention group. Parameters, that can be measured at home will be periodically telemedical monitored. In according with at home monitored data, the own physician will be able to intervene with change of medical treatment in the case of non-physiological deviations in order to improve the health status as well as the prognosis of the patient with CHF.
This study aims to investigate whether the investigators can improve heart function in patients with heart failure who have undergone cardiac resynchronization therapy, but have not had an improvement in their heart function at least one year after the procedure. The investigators will evaluate whether placing a new pacing lead (electrode) in a different part of the heart may increase heart function and decrease heart failure symptoms.
Heart failure with preserved ejection fraction (HPEF, defined as LVEF ≥50%) represents 50% of hospital admissions for heart failure. Although its morbi-mortality is similar to that of heart failure with reduced ejection fraction (HFPEF), it remains an unknown disease with limited data especially from an etiological point of view. The underlying causes are imperfectly understood, and more than half of the patients have HPEF labeled "idiopathic." A non-hierarchical clustering study of HPEF patients led to the identification of a subgroup of patients (25%) with a predominant coronary vascular phenotype (i.e., a history of coronary stenosis with or without the need for revascularization). In these patients, vascular endothelial dysfunction would play a central role in the development and progression of heart failure.One of the mechanisms leading to HPEF could be a decrease in the bioavailability of nitric oxide (NO) involved in the relaxation of the cardiac muscle. As the mechanism of action of NO is pleiotropic, a decrease in NO bioavailability could also be observed at the peripheral level, favoring in the long term the development of unfavorable vascular remodeling, for example in the small digital or retinal arteries.Some HPEF patients could thus be distinguished from others by their predominant "vascular" profile. The link between HPEF and endothelial dysfunction has been suspected but never clearly demonstrated. Ultra-high frequency ultrasound is an innovative technology to estimate the remodeling of small distal arteries in a non-invasive way. The investigators propose to use this imaging on digital arteries in HPEF patients and to study the association with known coronary macrovascular damage.The remodeling parameters will be measured and compared in patients with HPEF with or without identified macrovascular coronary disease.This characterization of arterial remodeling on the digital arteries could be a powerful tool for non-invasive screening in the identification of a subgroup of HPEF that is still considered idiopathic.
The objective of this study was to identify potential prognostic factors of sacubitril/valsartan vs Valsartan treatment response.
