Filter by:This study is a multicenter cohort study including patients diagnosed with aortic valve disease during hospitalization, including aortic insufficiency and aortic valve stenosis. The primary outcome of the study was all-cause death, and the secondary outcome was cardiovascular events. Through follow-up observation, the prognostic risk factors of patients with aortic disease were evaluated, and a prognostic model was constructed to guide clinical decision-making.
The aim of the study is to clarify whether the perioperative release of the cardiac biomarkers troponin I, troponin T and CK-MB consistently correlate with visualizable myocardial damage, and to what extent these biomarkers are comparable by means of their kinetics and dynamics. Due to the uncertainty regarding the validity of cardiac biomarkers in the diagnosis of myocardial infarction, the answer to these questions could have a considerable influence on internationally valid guidelines and definitions. International studies, especially in the field of coronary surgery and coronary artery disease treatment refer to these definitions, in particular, the adequate treatment of affected patients is directly dependent on them.
An observational cohort study of patients recruited presenting with valvular heart disease. The specialized investigations will focus on myocardial remodelling and scar formation/regression and extracardiac micro- and macro-vascular sequelae of valvular heart disease (VHD). The aim is to investigate the natural history of VHD and its ensuing cardiac and extracardiac end organ effects, the impact of existing interventions and the long-term outcome. We hope to establish the underlying causative aetiology of known associated conditions (e.g. vascular dementia) and to determine if extracardiac changes may serve as early biomarkers of prognosis in VHD. Participants will attend for two visits at Barts Heart Centre or Chenies Mews Imaging Centre and will undergo a panel of tests including cross-sectional cardiac imaging, point-of-care microvascular assessment and blood tests. Patient outcome will be assessed by data linkage to hospital episode statistic (HES) data and ONS data (via NHS spine). We aim to identify determinants that will help to improve patient selection and timing of valve intervention based on advanced clinical, blood and/or imaging biomarkers.
In this study, the investigators aim to use data identified through the hospital's integrated medical database and National Health Insurance database to explore the long-term performance and benefits of biological and mechanical valves. This research aims to provide more recommendations and references for valve replacement in different patient populations.
This is a prospective, multi-center, randomized effectiveness trial of the CardioGard Embolic Protection Cannula in high-risk valve surgery patients.
The goal of this open, prospective, multicenter study is analyze long-term outcomes of aortic/mitral valve replacement using the "UniLine" bioprosthesis in patients with acquired aortic or mitral valve diseases. Main research objectives: To analyze long-term (up to 12 years) outcome of aortic or mitral valve replacement using the "UniLine" bioprosthesis. To study the hemodynamic characteristics of normally functioning "UniLine " prostheses in the mitral or aortic valve position based on the transthoracic echocardiography data. To assess the number, type, time frames of dysfunctions of UniLine bioprostheses and the results of their treatment. To analyze the frequency of major serious adverse events associated with the "UniLine" bioprosthesis or procedure.
Rationale: Patients awaiting cardiac surgery can experience pre-procedural anxiety. This anxiety is associated with increased analgesic needs, increased risk of mortality and prolonged recovery time. Adequate patient education can help diminish pre-procedural anxiety and minimize postoperative complications. Recent studies have demonstrated that Virtual Reality (VR) can function as a useful tool to diminish pre-procedural anxiety in several medical fields. Especially 360 degree VR could familiarize patients with their clinical pathway. Nevertheless, limited to no research on the application of 360 degree VR has been conducted in the context of cardiothoracic surgery yet. Objective: The aim of this study is to explore the effects and possible benefits of 360 degree VR on pre-procedural anxiety in patients awaiting elective cardiac surgery involving a sternotomy, compared to standard forms of patient education. Study design: Single-center, randomized controlled trial Study population: Patients aged 18 or older awaiting elective cardiac surgery involving a sternotomy.
In order to perform heart surgery, a machine called cardiopulmonary bypass (CPB), or more commonly known as a heart-lung machine, is used to maintain the circulation of oxygenated blood needed by the rest of the body and its organs. Historically, when a patient is connected to CPB, their body is cooled below the normal body temperature. This is known as hypothermia. This is because scientific studies have previously shown that reduced body temperature lowers metabolism and therefore offers more protection to the brain and other organs due to the reduced oxygen requirement. The evidence supporting this practice, however, has been challenged throughout the history of cardiac surgery, with studies supporting that normothermia, or normal body temperature, is a safe alternative. Despite this, the practice of hypothermia has persisted. Published data from a survey of 139 cardiac surgeons in the United Kingdom showed that 84% still routinely employ hypothermic CPB during surgery. To assess whether normothermic or hypothermic CPB is safer, a clinical trial requiring a large sample size and high recruitment rates will be required. Therefore, the investigators aim to assess firstly the feasibility of trial recruitment and allocation adherence in this study. 100 adults across 10 different cardiac surgery centres in the United Kingdom will be recruited to a multicentre feasibility randomised controlled trial comparing normothermia (active comparator) against hypothermia (control comparator) during cardiopulmonary bypass in cardiac surgery. This study will also test the ability of the Cardiothoracic Interdisciplinary Research Network (CIRN), a trainee-led research collaborative, to collect pilot data on Major Adverse Cardiac and Cerebrovascular Events (MACCE) using a regulation-approved electronic application HealthBitⓇ. Participants will also be asked to complete quality of life surveys. The results of this study will subsequently inform a large, adequately powered randomised controlled trial for optimal temperature management during CPB.
The aim of this study is to evaluate feasibility, efficacy, and adherence of home-based cardiac rehabilitation with the integration of telemedicine. Several components will be assessed such as quality-of-life, nutritional counseling, maximum metabolic activity (MET's), diabetic management, tobacco cessation, lipid, blood pressure, and psychosocial management. These tasks will be accomplished through concurrent conversations between patients and their therapist's utilizing telemedicine with observed exercise training.
Heart problems are amongst the most common physical illnesses in children and young people (CYP). They can be present from birth or develop as CYP get older and are linked to increased physical and psychological difficulties overprotection from caregivers and healthcare providers and reduced quality of life. While adults are offered exercise classes and lifestyle advice after a heart problem, CYP with heart problems are not. Improving health behaviours in people with heart problems is vital, improves quality of life and reduces additional illnesses (i.e obesity, diabetes). Approximately 1 in 3 CYP with heart problems have anxiety and/or depression so it is also important to support their mental health. One way to do this is to develop and test the acceptability and feasibility of a trial of cardiac rehabilitation (CR) consisting of exercise with mental health support for CYP. The aim is to develop and test the feasibility and acceptability of a trial of a cardiac rehabilitation programme for CYP.
