Filter by:NH002 (Perflutren Lipid Microspheres) Injectable Suspension is an ultrasound contrast agent for use in patients with suboptimal echocardiograms to opacify the left ventricular (LV) chamber and to improve the delineation of the LV endocardial border. The primary objective of this study is to evaluate the safety and tolerability of 3 ascending doses of NH002.
This study is to see if the zero-heat-flux (ZHF) thermometry monitoring in cardiac surgery with moderate hypothermic cardiopulmonary bypass differs from Temp-NP, which reflects central body temperature 30 minutes after the end of the cardiac surgery.

Non-significant risk device study to conduct evaluation of the performance of new device for monitoring of cardiac function (based on previous iterations 510(k) 173156)
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.
The aim of the present study is to examine whether the nature based 'Wild man Programme' can help to increase quality of life among men on sick leave compared to treatment as usual. Additionally, the study examines which natural environments best work as supportive environments in the rehabilitation.
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.
Low-value care is defined as patient care that provides no net benefit to patients in specific clinical scenarios, and can cause patient harm. Prior research has documented high-rates of low-value care in Virginia; this work has helped to inspire a Virginia government-sponsored quality improvement initiative to reduce low-value care. Funded by an Arnold Ventures grant, six large health systems in Virginia volunteered to partner with the Virginia Center for Health Innovation (VCHI) to reduce use of nine low-value health services (three preoperative testing measures, two cardiac screening measures, one diagnostic eye imaging measure, one low-back pain opioid measure, one low-back pain imaging measure and one peripherally inserted central catheter [PICC] measure). These health systems include nearly 7000 clinicians practicing across more than 1000 sites. VCHI is implementing a nonrandomized physician peer-comparison feedback quality improvement intervention to reduce use of nine low-value services. Modeling will be used to identify and use propensity score matching to match six intervention health systems to six comparable control health systems. VCHI will provide education, quality improvement training and financial resources to each site, and VCHI will use the Milliman MedInsight Health Waste Calculator to create the peer comparison reports using the Virginia All Payer Claims Database (APCD). VCHI will use additional measures from The Agency for Healthcare Research and Quality (AHRQ). Additionally, VCHI will use AHRQ data to attribute physicians and health care facilities to health systems. The primary purpose of the initiative is to improve quality of care for Virginia residents and this initiative is not being done for research purposes. Nevertheless, University of California, Los Angeles (UCLA) plans to rigorously study and publish the impact of this intervention across the state of Virginia, which is why the UCLA team pre-registered the initiative. The UCLA team will use the Virginia APCD to evaluate the impact of the intervention. Please note: the APCD has a 1-year time-lag of data collection and is a dynamic database, meaning that its population of enrollees changes from year to year. This intervention was initially designed as a randomized step-wedge intervention; the intervention was delayed by the COVID-19 pandemic and began in September 2020 for all intervention groups. The intervention period was extended through December 2022. As a result, the initial design was modified.
The aim of our study is to find out whether high doses of vitamin C before cardiopulmonary bypass and during the first 24 hours after that have and impact of lowering the incidence of hyperlactatemia.
This study is designed as a repository study to collect resting cardiac phase signals and subject meta data from eligible subjects using the Phase Signal Recorder (PSR) prior to Right Heart Cath (RHC). The repository data will be used for the purposes of research, development, optimization and testing of machine-learning algorithms developed by CorVista Health (formerly Analytics 4 Life).
