Filter by:Over 100,000 coronary stent procedures, where small balloons are used to stretch open a narrowed blood vessel, are performed every year in the United Kingdom to treat people who have conditions such as angina or have suffered a heart attack. For most patients the risk of complications is low, but for some, there is a higher risk of their heart failing during the procedure. Heart failure is a serious complication which can need treatment with a life support machine and lead to major damage to the heart muscle or even death. These risks are greatest in patients with severely diseased heart arteries and those who already have weakened heart muscle. A new technology may be able to help with this problem. It consists of a small heart pump which is placed in the heart's main pumping chamber (the left ventricle, LV). This pump is known as a LV unloading device. The LV unloading device is inserted into the heart through a blood vessel in the leg and supports the heart muscle. It is removed at the end of the procedure or when the heart can pump safely on its own. Whilst this heart pump is promising, it comes with some risks of its own. These include bleeding and damage to the arteries in the legs. It is also expensive, costing £8,000 per operation. Currently, there is no strong evidence to guide the use of this device. The CHIP-BCIS3 study aims to determine whether these heart pumps are beneficial and cost-effective in patients receiving a stenting procedure who are at high-risk of complications.
Cardiovascular diseases are among the most common causes of death in kidney transplant patients. Physical activity is of great importance in preventing cardiovascular diseases after transplantation. Although regular physical activity is recommended in international guidelines to prevent post-transplant mortality and morbidity in kidney transplant patients, studies have shown that patients do not follow regular physical activity instructions.The aim of our project is to examine the effect of pedometer-assisted physical activity on metabolic parameters after kidney transplantation.
Sarcopenia is a skeletal muscle disease, characterised by low muscle strength and muscle mass, and associated with higher medical care costs, shorter life expectancy and physical dependence. Sarcopenia affects around 1 in 10 older adults in the general population. However, in patients with coronary heart disease (CHD), this number is almost 3 in 10. Patients who have CHD are offered cardiac rehabilitation (CR); a multicomponent programme designed to improve long-term health outcomes. Nutritional education is an important part of CR and typically focuses around modifying fat and carbohydrate intake to lower cholesterol levels and achieve a healthy weight. Currently there is little focus on increasing protein intake, which might reduce the risk of sarcopenia. Eligible patients with CHD and low protein intake will receive the standard nutritional education delivered during CR. Next, participants will be randomised to one of two groups: protein education (intervention), or standard information (control). Whilst COVID-19 restrictions are in place, education will be delivered remotely via pre-recorded video. Outcome measures, including protein intake, sit to stand performance, sarcopenia risk score (modified SARC-F), Physical Activity Vital Signs (PAVS) and waist circumference, will be assessed at baseline, at the end of the standard CR programme and after a follow-up period of the same duration as the CR programme.
Background & Significance. Children with congenital heart disease (CHD) have experienced improved postoperative survival shifting the focus away from minimizing mortality to curtailing morbidities. Critical illness following cardiac surgery induces catabolism which may impact functional status. Catabolism, a state in which protein breakdown exceeds protein synthesis, can lead to lean body mass (LBM) breakdown. LBM loss has been associated with poor clinical outcomes. Muscle ultrasound (mUS) has been utilized to measure LBM changes and the functional status score (FSS) was developed to assess functional status changes in children following hospitalization. The ability to identify LBM loss acutely and its association with FSS changes may lead to earlier interventions to preserve LBM and aid in outcome prediction. Specific Aims & Hypotheses. Specific Aim 1 is to identify the percent change in LBM by mUS during the first postoperative week in children following complex cardiac surgery. Specific Aim 2 is to evaluate the relationship between percent change in LBM during the first postoperative week and the FSS at discharge and 6 and 12-month follow-up in children with CHD following complex cardiac surgery. The investigators hypothesize children with CHD following complex cardiac surgery will experience a decline in LBM and that there is a direct relationship between the change in LBM and postoperative FSS follow-up. Study Design & Methods. The investigators are conducting a single-center, prospective, observational cohort study. Consecutive children (> 3 months and < 18 years of age) with CHD undergoing biventricular conversion will be enrolled. Patients will undergo a baseline mUS and FSS at the time of the index operation. Interval mUS will be obtained on the third and seventh postoperative day. Discharge mUS and FSS will be obtained and a remote FSS will be requested by the family at 6 and 12-months postoperatively. Demographics, pertinent laboratory, concomitant medications, nutrition and ultrasound variables will be collected. Outcomes. The primary outcomes will be change in LBM during the first postoperative week and change in FSS at 6 and 12-month follow-up in children following complex cardiac surgery. Change in LBM will be defined as a percent change in cross-sectional area of the quadriceps muscle layer thickness (QMLT). Change in FSS will be significant if the score drops 3 points or more from baseline at postoperative follow-up.
This study is an exploratory clinical study to observe the improvement of lung function before and after the treatment by human umbilical cord-derived mesenchymal stem cells, and the purpose is to evaluate the safety and effectiveness of human umbilical cord-derived mesenchymal stem cells on non-cardiac surgery-induced lung injury in patients with ischemic heart disease. The study is a randomized parallel controlled study. Patients receive a review of which main content includes symptom improvement, lung function improvement, and adverse events.
XueBiJing, a Chinese herbal derived therapeutic, has been approved to treat severe infections (sepsis) in critically ill patients (China Food and Drug Administration; Beijing, China, Number Z20040033). Cardiopulmonary bypass (CPB) will produce large amounts of inflammatory mediators and oxygen free radicals, which causes the lipid peroxidation damage and mononuclear cell migration, thus aggravating organ inflammation and damage. Therefore, exploring new methods to prevent and alleviate organ injury caused by CPB is an important topi in clinical practice. However, little knowledge is regarding the effect of Xuebijing injection on CPB-related organ injury. To answer these questions, the authors conducted this randomized trial to compare XueBiJing with placebo in critically ill patients with cardiovascular surgery.
Children born with congenital heart problems face numerous physical, developmental, and social challenges. Complications in pregnancy have potential to impair brain development, leading a smaller brain volume and less mature brain even in babies born at full term. As the brain is less mature, it may be more susceptible to oxygen deprivation and other forms of brain injury. Urgent surgery is often required in the first few weeks of life to improve functioning of the heart, but this surgery also carries a risk of additional brain injuries. The aim of this study is to provide a better understanding of factors associated with the development of brain injury in neonates undergoing heart surgery in the first year or life. The short-term aim of this study is to provide data to help our team to develop advanced monitoring software that can be used to guide perfusion of the brain during surgery with a view to preventing surgery-related brain injury. The mid-term goal of the study is to identify risk factors associated with brain injury and inflammation around the time of surgery, through using MRI and taking blood samples. A longer term aim of this study is to be able to follow the children as they develop to see if any problems develop later in life. In this study, we will ask parents to complete two brief questionnaires when their infant reaches 2 years of age. Overall, this study aims to improve our understanding of the causes of brain injury in patients born with congenital heart problems. The data provided by this study will help us to develop new tools for monitoring brain perfusion during surgery.
Objective to evaluate the effect of Shexiang Baoxin Pill on myocardial ischemia in patients with coronary microvascular dysfunction (non obstructive coronary heart disease) through a randomized, double-blind, placebo-controlled clinical multicenter study.At the same time, the effects of exercise tolerance and quality of life were also observed.
Chronic coronary syndrome (CCS) is a newly described classification devised by the European Society of Cardiology (ESC) 2019 to replace the term "Stable Coronary Artery Disease (CAD). The main reason for effecting the change is the term is thought to better describe the disease process and encompass a wider spectrum of clinical, pharmacological, and pathophysiological entities. Using this new term, the disease atherosclerosis manifests as CAD is categorized into Acute Coronary Syndrome (ACS) and CCS. The main focus of introducing the concept of CCS is on the fact that CAD is a continuous phenomenon involving intravascular plaque aggregation and progression which has different evolutionary phases. Dyslipidemia is recognized as a prominent risk factor for cardiovascular (CV) disease. It is characterized by an elevation of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), or triglycerides (TG) and reduced serum high-density lipoprotein cholesterol (HDL-C) concentration . Genetically determined and metabolically induced disturbances in lipid metabolism, as manifested in several types of dyslipidemia, have been shown to be causally related to the development of coronary artery disease (CAD). A diversity of clinical and angiographic studies has been made to evaluate the linkage between plasma lipid-control therapy in the development of recurrent cardiovascular events. Independent predictors of recurrent CVD events or death include age, smoking, hypertension (HTN), dyslipidemia, diabetes mellitus, chronic kidney disease, and the underutilization of medications recommended by current treatment guidelines.
