Filter by:Non-obstetrical drivers of adverse pregnancy outcomes are underappreciated. Latent structural heart disease may account for a substantial proportion of adverse pregnancy outcomes in low-resource settings. Pregnant women presenting to B.P. Koirala Institute of Health Sciences will be prospectively included into a registry upon their visit for antenatal care. Women will be followed until 6 weeks after the time of delivery. Nested within this registry, the investigators will perform a registry-based adaptive cluster randomized crossover trial. The trial compares an experimental condition (echocardiographic screening) and a control condition (routine antenatal care).
In adolescents with congenital heart disease physical activity level is reduced which is why promotion to a more active lifestyle with an age-appropriate and modern intervention is needed. In healthy subjects digital health nudging was shown to increase physical activity. However, in adolescents with congenital heart disease such studies have not been conducted yet. In this RCT participants receive daily, short smartphone messages with the primary purpose to increase daily physical activity, which is monitored with a "Garmin vivofit jr." wearable.
The purpose of this study is to assess whether the use of physiology parameters as guidance post-percutaneous coronary interventions (PCI) is associated with less risks of target vessel failure (TVF) and angina-related events than standard angiographic guidance.
The purposes of this study is to standardize the process of formulating exercise prescriptions for coronary heart disease（CHD）, verify the safety and effectiveness of exercise prescriptions, and establish a database of exercise prescriptions for CHD, with a view to providing new solutions for cardiac rehabilitation.
To prospectively investigate the efficacy of an insertable cardiac monitor-guided atrial fibrillation (AF) management in reducing subsequent AF burden in patients with persistent or paroxysmal AF undergoing atrial catheter ablation (CA).
Malformations of the heart are common; 1.35 million infants are born each year with congenital heart disease. Many of these defects carry a considerable threat to the individual's quality of life as well as survival. Along with focused medical management, surgical repair remains a standard of care for more than 25,000 infants and children each year in the United States and Canada. The care of individuals with congenital heart disease is highly complex and has significant risks of morbidity and mortality. Most cardiac operations require the use of cardiopulmonary bypass (CPB, also known as the heart-lung machine) to safely access the inner chambers of the heart. CPB itself has been well documented to cause significant inflammation and hemodilution as the individual's blood is passed through a foreign circuit. This inflammatory response can lead to fluid overload, distributive shock and potential end-organ dysfunction in the heart, lungs, kidneys, brain, liver or bowels. These organ dysfunctions may culminate in post-operative low cardiac output syndrome (LCOS), prolonged ventilation time, prolonged intensive care unit (ICU) stay and can contribute to mortality. Dampening the inflammatory response from CPB has been a focus of research interest for years. Intra-operative ultrafiltration has been used to remove excess fluids and filter off inflammatory cytokines during cardiac operations. Over 90% of children's heart centers in the world utilize some form of ultrafiltration (mostly some form of modified ultrafiltration), but there are wide variations in published ultrafiltration protocols (none of which are combination SBUF-SMUF in children). Ultimately, this project seeks to provide high-quality evidence that the immunologic and clinical effects of combination SBUF-SMUF are rate dependent. Therefore, a randomized study directly comparing a high-exchange SBUF-SMUF (60ml/kg/hr) and a low-exchange SBUF-SMUF (6ml/kg/hr) can identify which is the optimal ultrafiltration protocol to enhance post-operative clinical outcomes for this patient population. The expected data and results could be immediately applicable to improve recovery after heart surgery for infants and children across Canada and the rest of the world at large.
Chronic kidney disease is an independent risk factor for cardiovascular disease associated with increased mortality rate during cardiac surgery in proportion to the kidney function. Chronic kidney disease is defined by decreased glomerular filtration rate (GFR) as classified by Kidney Disease: Improving Global Outcome (KDIGO). Deterioration of kidney function has a complex and multifactorial pathophysiologic derangement. In order to counter kidney injury associated with cardiac surgery, several pharmacologic and non-pharmacologic interventions have been studied to prevent perioperative deterioration of kidney function. Diuretics as pharmacologic measure are often used post-cardiac surgery to treat fluid overload and managing patient with acute kidney injury by preventing anuria. Loop diuretics (furosemide) may improve renal blood flow, decrease reabsorption in renal tubules, decrease oxygen demand and energy consumption (blocking potassium/sodium/2cloride co-transport in loop of Henle), and prevent hypoxic injury of renal medulla. Low dose continuous furosemide hypothetically has a protective effect on cardiac surgery patients with kidney dysfunction, measured improved glomerular filtration rate, decreased indication for therapeutic furosemide infusion, and decreased need of renal replacement therapy. On the other hand, administration of furosemide is rather harmful in severe kidney dysfunction. Therefore, the objective of this study is to determine the protective effect of low-dose continuous furosemide perioperative in cardiac surgery patients with mild to moderate kidney dysfunction.
This study is planned to assess the effect of obesity (BMI over 30 kg / m2) on hospital outcomes of isolated coronary artery bypass grafting in patients with chronic ischemic heart disease.
Researchers want to better understand what happens to the heart when the autologous (from one's own body) stem cells are injected directly into muscle of the right side of the heart during the Fontan (Stage III) surgery. They want to see if there are changes in the electrical activity, the structure, and the function of the heart following this stem cell-based therapy. Researchers will compare the results from people who receive the stem cells to the results from people who do not receive the stem cells.
The Effect of Individualized Nutrition Training Given to the Families of Children with Congenital Heart Disease (CHD) in the Post-Operative Period on their Growth and Development This study was conducted experimentally to determine the effects of individualized nutrition training given to mothers of children who had surgery for CHD on their growth and development.
