Filter by:Congenital heart disease is the most common congenital malformation in the world with high morbidity and mortality. However, there is no data to assess the perioperative outcome of congenital heart disease surgery among Chinese cross-regional population. This study aims to investigate the perioperative outcome of congenital heart disease surgery in childhood from a chinese cross-regional cohort.
A prospective, longitudinal, non-comparator, non-randomized observational cohort study to assess the quality of life in adult patients affected by hypertrophic cardiomyopathy and thoracic aortic dilatations who are not amenable to surgery, as well as those affected radiation-induced cardiac disease caused by radiation therapy.
Sleep-disordered breathing has a prevalence of 30~80% in patients with heart diseases. Various studies have revealed a correlation between the incidence and various diseases such as heart failure, hypertension, diabetes, and cerebral infarction. Postoperative acute kidney injury after heart surgery is one of the major complications with incidence with 40~50%, however, there has been no preventive method or treatment yet. Recently, several studies have been published that have shown a correlation between sleep-disordered breathing and renal impairment. In general, sleep-disordered breathing can be regulated easily with continues positive expiratory pressure, which means that early diagnosis and treatment of sleep-disordered breathing might help to reduce the incidence of postoperative acute kidney injury and improve patients' prognosis. In this study, the investigators investigate the impact of sleep-disordered breathing (diagnosed by oxygen desaturation index ≥5) on the incidence of postoperative acute kidney injury in patients undergoing valvular heart surgery.
n Tan Tock Seng (TTSH), Acute myocardial infarction (AMI) is one of the top 4 reasons for admissions with 948 percutaneous coronary intervention (PCI) procedures done in year 2016. International guidelines recommend that all patients complete CR after PCI, as it plays a critical role in reducing five-year cardiovascular mortality and the risk of cardiovascular-related hospital admission. However, the rate of completion of CR has been found to be low as only 19% of post PCI patients completed CR in 2016. According to a patient survey conducted, the main reason for non-completion is the inconvenience experienced by patients from needing to return to hospital weekly. In addition, poor compliance to prescribed home exercises limits the effectiveness of exercise training. Hence, there is a pertinent need to activate patients to engage in self-directed CR in a safe and effective manner to target these issues. Current solutions to increase participation and compliance involve strategies have been limited. Participation and compliance to prescribed exercises recorded via brochures and activity diaries have been limited by difficulties experienced by patients when providing this information, posing a risk of recall bias or the risk of misplacing their activity logs. Mobile applications targeted at increasing fitness addresses the problem of the risk of misplacing activity logs but is still subjected to recall bias as self-input of multiple data is required. Exercise guidelines within these applications are also generic and does not adhere to international exercise training guidelines targeted at patients after coronary revascularisation. In order to address these gaps, there is a need for a technology enabled solution that can provide evidence-based CR programme with constant HR monitoring which offers direct feedback to the patients and at the same time affordable and easy to use. "Heart-Track" is a novel mobile app based CR model of care that utilises a technology-enabled device designed specifically for patients post PCI to complete CR at their convenience, while ensuring that evidence-based clinical outcomes are achieved.
In this clinical study the investigators will compare blood pressure measurements obtained using the non-invasive, wireless Biobeat monitoring device (both a wrist watch and a patch configuration) to an invasive arterial line catheter (radial or femoral) and a Swan Ganz Catheter in 20 patients immediately after cardiac surgery, at the cardiac intensive care unit.
Magnetic resonance imaging (MRI) is increasingly an important tool for diagnosis and management of cardiac diseases in children. One of the uses of MRI is tissue characterisation, in which the signal characteristics of the cardiac muscle (myocardium) can be determined with special techniques, known as parametric mapping. There is increasing evidence that parametric mapping may be able to identify regions of scarring in the myocardium, or detection of oedema/inflammation in the setting. This in turn can help predict disease course and add value to the management of patients. There is also evidence that other structures that are visualised in parametric mapping aside from the heart (e.g. liver and spleen) can also help improve diagnostic accuracy and guide management. Currently the majority of studies describing the use of parametric mapping is focused on adults, with limited data on its use in children. The parametric mapping values can also differ amongst different machines, so calibration with normal subjects are also required.
The concept of the "ischemic cascade" is generally accepted hypothesis, according to which whenever ischemia of the myocardium occurs there is a consequence of events, that always occur in a given order - diastolic dysfunction first, followed by systolic dysfunction, then changes on electrocardiogram (ECG) and finally chest pain sensation. The occurrence of every next stage of cascade means more severe ischemia and respectively - more severe myocardial damage. We propose that mechanical and electrical changes in the myocardium during ischemia appear simultaneously.
Topic: Effectiveness of the nurse-led support programme using a mobile application versus telephone advice on patients at risk of coronary heart disease - a randomized controlled trial Aims: The study aims to compare the effects of a nurse-led support programme using a mobile application versus telephone advice on patients at risk of coronary heart disease who have been discharged from the emergency department (ED). Methods: A multi-centre, single-blinded, randomized controlled trial will be conducted. 80 patients diagnosed as being at risk of CHD, able to use a smart phone, and who have been discharged from the ED will be randomized into the App Support Programme (ASP) group or the Telephone Support (TS) group. All participants will receive standard medical and nursing care on discharge. The ASP group will receive an app whereas the TS group will receive telephone support provided by the nurse for 20 minutes bi-weekly. The self-developed mobile app will support clients in managing their health problems and lifestyle. It is comprised of: (1) a knowledge health platform, (2) a membership area for individual health measures and exercise records, (3) a Chest Pain - Things to Do List, and (4) an individual reminder and measure feedback system. Health outcomes will be collected at baseline (T0), 1 month (T1), 3 months (T2). The primary outcome is Self-efficacy and self-management behavior. Secondary outcomes are: (i) ED and hospitalization frequency; (ii) Physiological health profile and cardiovascular functional endurance; (3) total amount of exercise; (4) perceived stress level; (5) health literacy; and (6) quality of life. Data analysis: A Generalized Estimating Equations model will be used to assess differential changes in all outcome variables.
The proposed study will be a prospective, randomized, double blind, placebo controlled trial to compare the use of a continuous infusion versus intermittent ketorolac on postoperative patients in the pediatric cardiovascular ICU. We intend to determine if the continuous infusion leads to a decreased utilization of opiates when compared to intermittent ketorolac.
The objective of this research proposal is to find out whether comparing the two different anaesthetic maintenance techniques (Propofol vs volatile anaesthetics) in adult patients undergoing heart surgery is practical for the anaesthetist treating the patients and whether it is feasible for the research team to recruit patients and follow them up after the operation.
