Filter by:The aim of this study is to understand the importance of resveratrol supplementation as a possible adjuvant in improving the metabolic profile and cardiovascular autonomic recovery of individuals with overweight and grade I obesity, reducing the incidence of diseases associated with obesity and the costs in primary, secondary and tertiary care.
This randomized, blinded, sham-control trial aims to evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for essential hypertension.
Consecutive obstetric patients attending routine antenatal visits were enrolled in this ongoing registry. A standardized 2D transthoracic echocardiogram (TTE) protocol was employed. Ejection fraction (EF) was quantified using biplane Simpson's method.
The Congenital Heart Disease Physical Activity Lifestyle Intervention Study (CHD-PALS) V.2 seeks to determine the efficacy of a lifestyle intervention program for adolescents and young adults (AYAs) with congenital heart disease (CHD). This trial was adapted from the original CHD-PAL trial to continue improving cardiovascular outcomes for transition-aged CHD survivors.
Older people with HIV (OPWH) are disproportionately impacted by cardiovascular disease (CVD) attributable to behavioral risk factors, and chronic HIV immune dysregulation resulting inflammation. Systemic inflammation is exacerbated by psychological distress via activating the immune response and driving pro-inflammatory CVD risk behaviors. There is promising evidence to suggest that mindfulness could be an effective intervention to reduce psychological distress and support behaviorally- and inflammatory-mediated CVD risk reduction. This project aims to refine and synthesize mindfulness and behavior change content from evidence-based protocols (mindfulness-based stress reduction and diabetes prevention program) to develop and pilot test a new text message-enhanced intervention called "One Mind One Heart" (OM-OH) using feedback from semi-structured interviews with OPWH in psychological distress (N=20), and my multidisciplinary mentorship team (Aim 1). An open pilot (N=5) with exit interviews and pre-post self-report assessments, will inform the initial acceptability of OM-OH and further refine OM-OH as needed (Aim 2). Finally, a pilot randomized controlled trial (RCT; N=50) will be conducted to a.) evaluate benchmarks of feasibility and acceptability of study methods and refined OM-OH compared to enhanced usual care, and b.) investigate potential for effects on psychological distress, inflammation, and behavioral CVD risk (Aim 3). Findings will provide the foundation for an R01 application to conduct an efficacy trial of OM-OH to reduce inflammatory-mediated CVD risk among OPWH.
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.
Antiphospholipid syndrome (APS) has a close association with ischemic stroke; however, the optimal treatment strategy for APS-related stroke has yet to be established. The clinical guidelines suggest using warfarin for APS-related stroke, but these suggestions are largely based on retrospective studies from the 1990s and expert opinion, rather than high-quality clinical trials. Moreover, the evidence on the role of antiplatelet drugs other than aspirin (e.g., clopidogrel) in APS-related stroke is particularly limited. Considering the relatively young age of patients with APS and the high clinical burden of using warfarin, it is necessary to verify whether warfarin is essential. Thus, the investigators aim to compare clopidogrel-based antiplatelet therapy and warfarin as a secondary preventive medication for patients with APS-related stroke. APS-STROKE is an exploratory, multicenter, prospective, randomized, open, blinded-endpoint clinical trial. Adult patients with definite APS who have a history of ischemic stroke will be included. Patients with high-risk APS (triple positivity or persistently high titers of anti-cardiolipin or anti-β2-glycoprotein I antibodies), systemic lupus erythematous, or indications for continued antiplatelet or anticoagulant therapy will be excluded. Eligible patients will be 1:1 randomized to receive clopidogrel-based antiplatelet therapy or warfarin. Patients assigned to the clopidogrel-based antiplatelet therapy group will be permitted to use additional antiplatelet drugs other than clopidogrel at the investigator's discretion. The primary outcome is a composite of any death, major adverse cardiovascular events, systemic thromboembolic events, and major bleeding during a follow-up period of at least 2 years. This study would provide valuable information for determining the optimal secondary prevention strategy for APS-related stroke.
People released from prison experience two times higher cardiovascular (CV) mortality than the general population, have a high prevalence of poor CV health and increased risk of CV events within 2 years of release. Access to high quality healthcare following release from prison is key to preventing poor health and CV outcomes. Our study team will investigate facilitators and barriers to health care access experienced by people released from prison.
In this clinical study the investigators will evaluate if it is feasible to pre-operatively identify low-risk patients, and to identify patients with cardiac pathologies with the LynxPatch.
The goal of this observational cross-sectional study is to analyze the effect of cardiovascular risk factors in healthy and asymptomatic populations. The main questions it aims to answer are: - Does the combination of the presence of different risk factors increase the risk for abnormalities appearing on electrocardiograms, such as ischemia, arrhythmia, and hemodynamics effects during and at the peak of effort of treadmill exercise test? - What are the main differences observed in the recovery period? Participants will answer an anamnesis of risk factors such as sex, race, age, familiar history of coronary artery disease, overweight or obesity, smoking, stress, and physical activity practice and perform treadmill exercise test on Ellestad protocol. If there a comparison groups: Researchers will compare individuals with most risk factors with those without, to see the cardiovascular responses.
