Filter by:Low magnesium levels are surprisingly common in those with a heart condition known as HFpEF, where the heart pumps well but is too rigid to fill properly with blood. While routine blood tests can check magnesium levels, they don't tell us how much magnesium is actually inside the heart and muscle cells, where it's vital for energy and overall function. Our research aims to get a clearer picture by looking directly at the magnesium inside these cells and understanding its role in the body's energy production and usage. We're also interested in how magnesium levels affect symptoms and the body's handling of sugar. We're using advanced medical imaging techniques, like heart magnetic resonance imaging (MRI) and other heart and muscle function tests, at rest and when the heart is working hard to help answer these questions. We'll compare the magnesium levels inside the cells before and after giving a supplement of magnesium to see if this can make a difference in how the heart and muscles work.
Arterial hypotension is a frequent complication of general anesthesia and a significant contributor to postoperative complications. It is a critical marker for the development of acute renal failure and postoperative myocardial infarction. Chronic heart failure (CHF) patients are increasingly encountered in the operating room, and their perioperative morbidity and mortality are substantial, with specific management lacking precise recommendations. The main objective is to assess the impact of a diluted norepinephrine bolus on cardiac output in chronic heart failure patients experiencing arterial hypotension after anesthesia induction.
Congestive heart failure (CHF) occurs when the heart is weak and not able to effectively pump blood to the body. One of the common manifestations of CHF is fluid overload and swelling of the legs. Diuretics or "water pills" are usually the treatment for fluid overload and leg swelling; however, in some patients' diuretics are no longer effective or the effectiveness is limited due to poor kidney function. The presence of chronic swelling of the legs could potentially damage the veins; additionally, it could lead to chronic skin changes in the legs and in the worst cases to a leg ulcer. Compression stockings are used in patients with venous diseases to reduce the swelling of the legs and improve mobility and quality of life. Although, there is a theoretical risk that compression stockings might push the fluid of the legs back to the heart and lungs worsening the CHF. The purpose of this study is to determine whether the use of knee-high tight socks (tight stockings with strong compression) vs. knee-high soft socks (soft stockings with minimum compression) are effective in preventing swelling and skin changes and safe in patients with CHF. During the first visit (in-person) a routine medical test will be performed including blood tests, review of the medication doses, current weight, an ultrasound images of the veins, (venous reflux ultrasound), questions about health status and a brief physical exam. The participants will be randomly assigned to receive tight compression vs. soft compression socks. Participants will be asked to wear the socks at least 8 hours a day for 5 days a week. There will be a total of 3 virtual visit (by video or telephone); the first one after one week, then after one month and two months. During the virtual visit participants will be asked about symptoms, current medications and doses, and current weight. The participants are expected to return to the clinic after 3 months for a second in-person visit. During this visit the investigators will ask questions about participant's health, they will perform a brief physical exam of their legs, and check participants weight and medicines; also, a venous ultrasound of the legs, questions about health status will be performed. The duration of the study is 3 months.
The aim of prospective, open label, single center, randomized controlled trial is to investigate the efficacy of enavogliflozin on exercise performance, diastolic dysfunction, and quality of life in patients with heart failure with preserved ejection fraction (HFpEF).
We propose a pilot trial examining the effectiveness of a mHealth-based home cardiac rehabilitation program using a telemedicine platform for the identification, recruitment, and retention of an underserved rural population with heart failure with reduced ejection fraction.(HFrEF). The goal of the pilot trial will be to demonstrate the feasibility of a telemedicine platform for the recruitment and retention of underserved rural patients in clinical trials. Participants will participate in a cardiac rehabilitation program delivered through a smartphone application called Movn. They will be monitored for 14 weeks.
Evaluate the pharmacokinetic and pharmacodynamic characteristics of Jia Shen Tablets in patients with Chronic Heart Failure.
This is a 22-subject prospective, multicenter, single-arm clinical trial to evaluate the safety and effectiveness of the Jarvik 2015 left ventricular assist device (LVAD) as a bridge to heart transplant in children weighing 8 to 30 kilograms. Data generated from the study will be used to support FDA review and potential approval of the device under the Humanitarian Device Exemption (HDE) regulation, the FDA approval pathway for devices intended to treat rare and orphan diseases.
Introduction: Suppression of tumorigenicity 2 (ST2) is a receptor member belongs to the Interleukin-1 (IL-1) family. The ligand and soluble versions are its two isoforms. The interleukin-33-ST2 ligand complexs development provides protection against heart fibrosis and hypertrophy. Investigations on heart failure in adults has demonstrated that it does not change by age, body mass index (BMI), creatinine, hemoglobin, and albumin levels, in contrast to NT pro brain natriuretric peptit. In adult heart failure patients, it has been demonstrated to be an independent predictor of mortality and cardiovascular events. The most recent guideline recommends using it as class 2b in the diagnosis of adult heart failure. Studies on ST2 in children are rare. The purpose of this study is to assess the prognostic value of ST2 for cardiovascular events in young individuals suffering from heart failure. Method: The study included pediatric patients (0-18 years old) with congenital heart disease or cardiomyopathy who needed medical care as well as surgical or interventional treatment. Height, weight, gender, saturation, heart failure classification (Ross or New York heart Assosiation), medications taken, the electrocardiogram, echocardiography, Pro BNP, and sST2 values of the patients, as well as any hospitalization, lower respiratory tract infection, organ dysfunction, or need for angiography or surgery during follow-up Data on arrhythmia and death were gathered during a 1-year follow-up. The SPSS software application was used to carry out the statistical analysis.
Establish a follow-up management system for pediatric heart failure and a registration platform for end-stage heart failure
This is a prospective cohort study, where we aim to investigate the effect of implementation of an electronic nudge alerting clinicians to the prescription of the 4 key pharmacological classes for the treatment of patients with heart failure and reduced ejection fraction (HFrEF) at the outpatient clinic in the Netherlands.
