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.
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.
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.
This a single-center, retrospective, observational study of patients that undergo coronary sinus(CS) lead revision, comparing epicardial lead placement to coronary sinus pacing(CSP) in those that had lead failure.
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 our research is to evaluate the effectiveness of an innovative medical device designed to measure foot and lower leg sizes in detecting early indications of deteriorating heart failure. This health condition frequently causes leg swelling and breathing difficulties due to fluid accumulation. Early detection of these symptoms is vital for effective management, potentially preventing the need for hospitalization. Fluid retention in the lower legs and lungs, manifesting as swollen ankles and shortness of breath, is a common sign of progressing heart failure. Often, a slight increase in body weight is the first warning of fluid accumulation, occurring before noticeable swelling or breathing issues arise. Early identification of these fluid accumulation signs is critical for timely intervention, which can avert the necessity for hospital admittance. Patients are usually encouraged to monitor their weight, check for swelling in the ankles, observe their breathing, and consult with their healthcare provider or heart failure specialist at the first sign of these symptoms. In many cases, patients can report these symptoms in time for their healthcare team to adjust their treatment accordingly. Diuretics, or water pills, are often prescribed to help eliminate excess fluid, effectively preventing hospital admissions when used promptly. The Heartfelt device may provide a useful solution for individuals who find it challenging to consistently monitor these indicators and their weight. It is designed to detect early warning signs seamlessly without imposing additional tasks on the patient's daily routine. The device, intended to complement rather than replace self-monitoring practices, is user-friendly and operates by scanning the feet for any size changes, positioned conveniently by the bedroom floor. This capability allows healthcare professionals to make informed decisions swiftly about patient care, potentially adjusting treatments to avoid further health complications. The device captures images of the feet only, ensuring privacy. This study aims to ascertain the device's practical effectiveness in real-world scenarios, aiming to collect precise data to confirm its potential benefits for patients facing heart failure challenges.
