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.
The purpose of this study is to determine the safety and effectiveness of ultrahigh dose diuretics compared to standard dose diuretics over 24 hours in patients with decompensated heart failure.
In a prospective observational cohort study (n = 250) the investigators aim to assess the correlation between cardiac biomarkers, advanced echocardiography and HS severity and determine whether these are prognostic markers of heart disease in patients suffering from hidradenitis suppurativa (HS).
The purpose of this study is to examine the implementation, intervention effectiveness, and dissemination of a digital acute care delivery model for improving selected health outcomes in the Hospital at Home population.
The aim of this study is to identify existing definitions and therapeutic approaches for acute right ventricular injury (RVI) in patients receiving extracorporeal membrane oxygenation (ECMO) for respiratory support. The objective of the study is to generate expert consensus statements on the definition and management of acute RVI in this high-risk patient population, using a Delphi method. The standardised RVI definition during ECMO for respiratory support and a consensus-based management approach to RVI will facilitate systematic aggregation of data across clinical trials to harmonise patient selection and compare therapeutic interventions.
This clinical study will utilize allogenic bone marrow-derived culture-expanded MSC that are expanded from the NK1R+ Mesenchymal stem cells as a therapy for chronic ischemic left ventricular dysfunction delivered using the investigational Helix transendocardial delivery catheter.
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
