Filter by:Heart failure is a syndrome that progresses with symptoms and signs caused by cardiac dysfunction and results in a shortened life expectancy (1). Acute heart failure resulting in hospitalization is a significant cause of morbidity and mortality. With the increase in the severity of the disease and rapid advances in the treatment of heart failure, these patients are frequently hospitalized and monitored in intensive care. (2) Five years after diagnosis, mortality can be up to 67%. Additionally, it is known that patients with heart failure are hospitalized on average once a year after diagnosis. (3) In a multicenter study, it constituted 14% of 3000 cardiac patients admitted to intensive care units. Additionally, due to longer ICU stays, these patients accounted for 33% of total inpatient days. An increasing number of heart failure patients require intensive care due to respiratory failure, regardless of left ventricular ejection fraction. Heart failure accounts for approximately one-third of patient days in intensive care units, and this burden is increasing. This shows that attention should be paid to the quality of care for patients requiring critical care. (2) Multidisciplinary programs have been implemented to deal with the high prevalence. However, the optimal follow-up frequency is unknown. Therefore, some tools are needed to improve patient prognosis (3). Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker whose values in both urine and plasma have been associated with acute kidney injury (AKI). Although NGAL is an early specific biomarker for AKI, it has not yet come into routine use, but is frequently used in clinical and experimental studies (4). Venous load ultrasonography score (VExUS) is a new systemic congestion scoring method based on inferior vena cava dilation and pulsed wave Doppler (PW-Doppler) morphology of the hepatic, portal and renal veins. It has been proposed as a score to assess systemic congestion.
The objective of this pilot study is to establish evidence to support the validity of HT in improving skeletal muscle function and physical capacity of patients with HFpEF. Our central hypothesis is that HT treatment will lead to improvements in skeletal muscle and microvascular function compared to a control intervention. As a result, we anticipate that patients treated with HT will demonstrate improved skeletal muscle microvascular blood flow and oxygenation resulting in enhanced exercise tolerance. To explore this hypothesis, we propose the following specific aim: Explore the effects of home-based HT on exercise tolerance in patients with HFpEF.
The goal of this clinical trial is to test a new type of pacemaker in heart failure patients following a heart bypass operation. The new pacemaker restores respiratory sinus arrhythmia which is a natural pattern where the heart rate increases when the participants breathe in and slows down when participants breathe out. The main questions the trial aims to answer are: - Is the new type of pacemaker safe? - Does the new type of pacemaker improve how patients' hearts work (also known as cardiac output)? Participants will have a range of tests before their operation and during their recovery in hospital while participants have the new type of pacemaker in place, and will be monitored very closely. Participants will also receive a phone call 1 month after their surgery. Researchers will compare the new type of heart pacing against standard treatment to see if it is as safe, and if it is any better for patients.
Chronic heart failure affects up to three million people in Germany, with prevalence increasing with age. It is a leading cause of cardiovascular disease-related deaths. Patients with heart failure undergoing non-cardiac surgery face higher risks of complications and death compared to those with coronary artery disease. Despite guidelines recommending comprehensive preoperative evaluation, there is no systematic risk assessment structure in place, leading to inadequate perioperative care. This study aims to evaluate a multidisciplinary approach for high-risk patients aged 65 and above, regardless of prior heart failure diagnosis, to mitigate postoperative complications. The investigators measure the NTpro BNP before surgery and include patients with NTproBNP> 450 in this study and randomize them either to the standard care group or the intervention group.The hypothesis is that standardized risk screening and multidimensional care (Intervention group) can reduce complications in these patients undergoing non-cardiac surgery.
This retrospective (between April 2020 and December 2023) then prospective (between January 2024 and August 2026), non-interventional cohort study has as its main objective to evaluate the clinical and therapeutic characteristics of patients aged 75 and over hospitalized in geriatrics for heart failure and also to evaluate the clinical characteristics and triggering factor(s) of acute heart failure.
Heart failure (HF) is a complex clinical syndrome associated with impaired heart function, poor quality of life for patients and high healthcare costs. Accurate risk stratification and early diagnosis in HF are challenging as signs and symptoms are non-specific. Here the investigators propose to address this global challenge by developing novel analytic methods for HF (STRATIFYHF). A prospective clinical study will collect patient-specific data related to medical history, a physical examination for signs and symptoms, blood tests including natriuretic peptides, an electrocardiogram (ECG), an echocardiogram (ultrasound of the heart), cardiovascular magnetic resonance imaging (MRI), demographic, socio-economic and lifestyle data along with novel technologies (cardiac output response to stress (CORS) test and voice recognition biomarkers) from individuals at-risk of developing HF and those with a confirmed diagnosis of HF. STRATIFYHF will use these data to support clinical validation of an artificial intelligence (AI)-driven decision support system (DSS) and mobile application for risk prediction, diagnosis, and progression of HF to enhance patients' quality of life and lead to more cost-effective health care.
This study aims to determine whether a 6-month multilevel intervention involving problem-solving training, exercise training and support from community health workers is more effective in improving outcomes for individuals with low socioeconomic status, type 2 diabetes, obesity, and early cardiac dysfunction than receiving education and access to a community exercise facility.
The objective of this study is to prospectively compare decongestive therapy administered by the Reprieve DMS system to Optimal Diuretic Therapy (ODT) in the treatment of patients diagnosed with acute decompensated heart failure (ADHF). The main objective is to determine if the Reprieve DMS is non-inferior to state-of-the-art urine sodium guided aggressive diuretic titration in two European HF centers of excellence.
The REFORM-HF study aims to test a new technology, AquaPass, designed to assist patients experiencing symptoms of fluid overload due to Heart Failure. Patients will wear a lightweight suit that helps remove excess fluids through their sweat. The investigators want to see if the AquaPass system can remove an additional 500mL of fluids during treatment, alongside patients' regular medications like diuretics. Participants will select if to be treated at their home or in the outpatient clinic.
