Filter by:Acute Decompensated Heart Failure ADHF is one of the leading causes of hospitalization. ADHF is a growing global health problem affecting more than 26 million individuals worldwide Acute Kidney Injury AKI is a common event in the natural disease history of patients with Heart Failure HF, The clinical importance of the co-existence of acute cardiac and renal dysfunction, known as acute cardiorenal syndrome CRS, and its management have recieved great attention recently Various studies have employed different criteria to define and calssify AKI. According to Risk, Injury, and Failure; and Loss, and End-stage kidney disease RIFLE criteria formulated by the Acute Dialyisis Quality Initiative ADQI AKI can be divided into five stages; renal injury risk, renal impairment, renal failure, renal function loss, and end stage kidney disease
The Korotkoff Sounds（KS）, which have been in use for over a century, are widely regarded as the gold standard for measuring blood pressure. Furthermore, their potential extends beyond diagnosis and treatment of cardiovascular disease; however, research on the KS remains limited. Given the increasing incidence of heart failure (HF), there is a pressing need for a rapid and convenient prehospital screening method. In this study, we propose employing deep learning (DL) techniques to explore the feasibility of utilizing KS methodology in predicting functional changes in cardiac ejection fraction (LVEF) as an indicator of cardiac dysfunction.
The objectives of this trial are to determine whether, in critically ill ESKD patients randomization to fluid removal guided by lung and inferior vena cava ultrasound, compared to standard care, leads to Improved pulmonary congestion (primary outcome); and safety (secondary outcome) in the short-term.
The goal of this observational study is to learn about the composition and function of the gut microbiome in adults with chronic heart failure with reduced ejection fraction. The main questions the study aims to answer are: 1. How does the gut microbiome and its interactions with the host change over time in adults with chronic heart failure? 2. How do these changes relate to heart failure disease severity and complications?
The purpose of this post-approval study (PAS) is to evaluate the long-term safety and effectiveness of the CardioMEMS™ HF System using real-world evidence (RWE) methods.
This study adopted an experimental research design to explore the effects of a warm water foot bath program on fatigue, sleep, and heart rate variability in patients with heart failure. The subjects of the study were heart failure patients in the cardiology outpatient department. The patients were randomly assigned to the experimental group and the control group. The control group received routine care and wore an actigraph. The experimental group received 4 additional care in addition to routine care and wearing an actigraph. Weekly warm water foot bath, data collection includes subjective sleep quality and fatigue level, physiological measurements: sleep quality-sleep time and efficiency, and heart rate variability index.
The purpose of this study is to understand the effects of a ketone drink on exercise capacity and other cardiovascular parameters in patients with heart failure. In heart failure, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. There may be several reasons why these symptoms occur. This study is assessing whether the ketone drink can improve these symptoms. This drink has been given status by Food and Drug Administration as "generally regarded as safe". The use of DeltaG in this study is experimental. DeltaG has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study.
The clinical feasibility of 18F-FMBG cardiac PET imaging will be observed in sympathetic nervous system activity in patients with heart failure, predicted cardiac events, guided ICD implantation, and evaluated therapy efficiency.
This study will collect medical and background information from participants with diseases that affect the heart and blood vessels (cardiovascular disease). Participants will continue their normal care and will not get any treatment other than those the study doctor has prescribed.
Non-invasive ventilation (NIV) has been widely used in heart failure patients with supporting evidence. However, the drawbacks and contraindications associated with NIV limit its applicability in certain patients. Recently, high-flow oxygen therapy (HFOT) has gained popularity, particularly in the context of the COVID-19 pandemic, due to its documented benefits, improved patient comfort and fewer contraindications. Studies have suggested that HFOT can generate positive end-expiratory pressure (PEEP) similar to NIV, thereby increasing end-expiratory lung volume. However, the specific effects of PEEP remain unknown, as previous research only monitored the upper airway pressure. Therefore, this study aims to explore the flow-pressure relationship between HFOT and NIV in heart failure patients using electrical impedance tomography (EIT). This prospective randomized crossover clinical trial will be conducted at a single medical center with multiple intensive care units. Participants will be randomly assigned to Groups A and B using a computerized randomization process. Each group will undergo specific protocols for 5-10 minutes per phase, during which parameters including respiratory rate, heart rate, blood pressure, peripheral oxygen saturation, and oxygen concentration will be recorded. NIV will be administered in continuous positive airway pressure (CPAP) mode. Additional parameters such as tidal volume, respiratory rate, minute ventilation, leak flow, and peak inspiratory pressure will be recorded for NIV. The study protocols for Group A will follow the sequence of oxygen mask, HFOT 40L, HFOT 50L, HFOT 60L, oxygen mask, CPAP 4cmH2O, CPAP 5cmH2O, and CPAP 6cmH2O. Group B will follow the sequence of oxygen mask, CPAP 4cmH2O, CPAP 5cmH2O, CPAP 6cmH2O, oxygen mask, HFOT 40L, HFOT 50L, and HFOT 60L. This means that each intervention will be performed in the order listed, with one intervention completed before moving on to the next. The participants will be positioned in a semi-recumbent position at 45 degrees, and the EIT belt will be placed around the fifth (or sixth) intercostal space for monitoring. The EIT signals will be filtered with a cut-off frequency set at 10 beats below the current heart rate. The entire procedure is estimated to take approximately 1-1.5 hours, and recalibration will only be performed in case of significant signal abnormalities. All data will be stored for offline analysis.
