Filter by: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.
In this study, patients were retrospectively included, univariate and multivariate analysis of factors affecting their diagnosis inconsistencies was performed, and a new diagnostic model was constructed by logistic regression.
VT-10201 is an Open-label, Phase 1b, Single-ascending Dose Study That Will Evaluate the Safety of VERVE-102 Administered to Patients With Heterozygous Familial Hypercholesterolemia (HeFH) or Premature Coronary Artery Disease (CAD) Who Require Additional Lowering of LDL-C. VERVE-102 Uses Base-editing Technology Designed to Disrupt the Expression of the PCSK9 Gene in the Liver and Lower Circulating PCSK9 and LDL-C. This Study is Designed to Determine the Safety and Pharmacodynamic Profile of VERVE-102 in This Patient Population.
Investigators recently developed the APPROACH electronic patient reported outcome (ePROM) Survey and Clinician Report tools to collect individual results from online quality of life and health status surveys for patients with coronary heart disease, and report them back to their treating clinicians. This pilot interventional study uses a pre-post design to assess whether implementing the ePROM system into routine care is feasible and acceptable to patients and physicians, and to inform feasibility for a larger clinical trial. Specifically, the investigators aim to evaluate use of the ePROM Patient Survey and Clinician Report among eligible outpatients with known or suspected coronary artery disease and their cardiologists. Additionally, the investigators aim to determine if the use of the APPROACH ePROMs Clinician Report in routine medical encounters is acceptable (based on administrative burden, ease of use, and time required) to patients and clinicians, and supports effective communication for management of symptoms of coronary artery disease.
Exercise training in cardiac rehabilitation (rehab) is a key part of managing a patient with heart disease. It has been shown that cardiac patients who increase their aerobic ("cardio") fitness by exercise training live longer, have better quality of life, and stay out of hospitals more than patients who do not improve their aerobic fitness. The more a patient improves their aerobic fitness the greater the benefit. But it has been shown that more than half of patients do not improve their aerobic fitness even after participating in cardiac rehab. This may be related to how hard patients are asked to train (their training "intensity"). The way intensity is chosen in current programs is commonly based on a "one-size fits all" method that may not consider that different patients have different abilities. There are more personalized methods to determine training intensity that exist, but these have never been used in cardiac rehab. One method divides intensity into three zones (zone 1 = moderate intensity; zone 2 = heavy intensity; zone 3 = very high intensity) that are based on when an individuals' biological responses to exercise change. The purpose of this study is to see if this approach gives better results in terms of changes in aerobic fitness and if training in the different zones makes a difference. Three groups of patients will be asked to train for 3 months in one of the three intensity zones. Aerobic fitness before and after exercise training will be compared to see which intensity zone results in the largest change.
The present study is aimed to determine the safety and efficacy of Ticagrelor single antiplatelet therapy (SAPT) in patients with primary coronary small vessel disease at high risk of bleeding after drug coated balloon (DCB) therapy.
The goal of this clinical trial is to compare non-invasive myocardial perfusion reserve (MRR) to invasively measured MRR in patients suspected for coronary artery disease (CAD). The main question it aims to answer is: • what is the correlation and agreement between non-invasive and invasive MRR. Participants suspected for CAD and referred for invasive coronary angiogram (ICA) will receive a [15O]H2O-PET and coronary CT angiography preceding ICA. During ICA, microvascular resistance measurements will be performed using thermodilution.
The present study sought to explore the predictive value of radial wall strain (RWS, derived solely from angiograms) for coronary artery lesion progression compared with lesion vulnerability assessed by optical coherence tomography (OCT). The lesion progression at 1 year was defined as an increase of ≥20% in diameter stenosis based on quantitative coronary angiography (QCA) evaluation.
