Filter by:This is a prospective pilot study to evaluate the safety, tolerability and technical feasibility of utilizing carbon dioxide for assessing coronary blood flow in subjects with coronary artery disease.
Stress cardiac MRI is crucial for diagnosing coronary artery disease in adults. Currently, it is mainly performed with vasodilators in specialized centers. Introducing mobile CMR units could increase accessibility, especially in rural areas, potentially reducing unnecessary invasive procedures. The objectives include demonstrating the feasibility of mobile stress perfusion CMR, detecting CAD using Regadenoson, and evaluating the image quality of GE-267 in real-world scenarios.
To compare the clinical outcomes of fractional flow reserve (FFR)-guided strategy versus intravascular ultrasound (IVUS)-guided stent implantation after angiography-derived FFR-based decision-making.
This study will evaluate the impact of colchicine on the change in coronary flow reserve (CFR), a marker for coronary microvascular dysfunction (CMD), compared to placebo in patients with heart failure and ejection fraction above 40% (including patients with improved EF).
Coronary heart disease (CHD) stands as a foremost contributor to global mortality, characterized by complex pathogenesis that renders conventional "one-size-fits-all" preventive strategies inefficient. Therefore, the investigators designed a prospective, multi-center cohort study among patients hospitalized due to either confirmed or suspected CHD, which aimed to establish a holographic data set for the diagnosis and treatment of CHD and explore the impact of critical therapeutic strategies in the real world on the clinical outcomes of CHD patients, providing evidence to optimize the management pathway.
The objective of this study is to examine the safety and effectiveness, from both clinical and technical perspectives, of utilizing the 5G-Robotic VRS100 system in percutaneous coronary intervention (PCI).
A prospective, multicenter, observational, single-arm trial to validate CardioFlux MCG's ability to diagnose myocardial ischemia caused by coronary microvascular dysfunction in patients with suspected ischemia and confirmed no obstructive coronary artery disease (suspected INOCA) by using diagnostic measures of coronary flow reserve (CFR) via invasive angiography as a reference standard for diagnosis.
Background: Cardiovascular disease (CVD) is one of the leading causes of morbidity and mortality among dialysis patients. Eotaxin-1(also known as Eotaxin and CCL11), an eosinophil-specific chemoattractant that plays a role in a variety of pathologic conditions including allergy, coronary heart disease, and inflammatory bowel disease. CCL11 has been shown to be overexpressed in human atherosclerotic lesions. Moreover, eotaxin-1 levels are higher in non-uremic coronary artery disease patients than in healthy individuals. Methods: The study will enrolled 400 hemodialysis patients. Patients are diagnosed with coronary artery disease based on clinical presentation and confirmed by angiography. Serum eotaxin-1 and 8-isoprostane levels are determined by enzyme-linked immunosorbent assay (ELISA). High-sensitivity cTnI immunoassays and albumin redox state by high-performance liquid chromatography are used for measurements. Aim: In this study, we aimed to determine the eotaxin-1 concentrations of patients with coronary artery disease and to investigate the role of eotaxin-1 and markers of myocardial injury.
The goal of this multi-center observational study is to learn about the effectiveness of magnetocardiography in rapid and accurate identification of ischemia in patients with suspected NSTE-ACS.
The purpose of this study is to develop and evaluate a web-based nursing intervention aimed at increasing physical activity in people aged 65 years and older with coronary heart disease. This study aims to answer the following questions: 1. What are the needs of older adults living with coronary heart disease in terms of a web-based nursing intervention to help them increase their level of physical activity? 2. What is the acceptability (content, structure, usefulness) and feasibility (recruitment, retention, adherence, fidelity) of a web-based nursing intervention to support older adults living with coronary heart disease as they increase their level of physical activity? 3. What are the preliminary effects of the web-based nursing intervention on the physical activity level and quality of life of older adults living with coronary heart disease? 4. What are the qualitative impacts of the web-based nursing intervention as perceived by older adults on their physical activity level, quality of life, motivation, knowledge and self-efficacy? 5. How can the preliminary effects of a web-based nursing intervention, developed in response to the needs of older adults living with coronary heart disease, be illustrated by its impacts as perceived by older adults post-intervention? A web-based nursing intervention was developed based on the needs of seniors living with coronary heart disease. 30 older adults living with heart disease will take part in the 8-week intervention. The effects of the intervention will be evaluated on the physical activity level, quality of life, knowledge, motivation and self-efficacy of older adults.
