Filter by:Coronary heart disease(CHD), stroke, and hypertension are major diseases that seriously affect human health.Pathologic changes in the arteries involved in the above diseases mainly occur in the intimal or medial layer of the arteries. Among them, cardiovascular and cerebrovascular diseases (CHD and stroke) have become the top two causes of death worldwide, with elderly patients accounting for the vast majority. CHD is an important cause of death, and atherosclerosis (AS) is the main pathology underlying it.AS predominantly occurs in the intima layer, and the use of high-resolution imaging techniques to visualize anatomical changes in the intima-media layer of the arteries alone is valuable for the study of AS. Coronary computed tomographic angiography (CCTA) and intracranial vascular magnetic resonance angiography (MRA) can clearly visualize coronary and intracranial arterial lesions, measure luminal stenosis and other important information, and provide a basis for diagnosis, treatment and prognosis of the disease. By integrating CCTA/MRA/Ultrasound multimodal imaging technology, investigators aim to develop a non-invasive CHD and stroke intelligent screening and evaluation system, which is bound to have great clinical and social value. This study is a national multi-center follow-up observational study, which is expected to collect and establish a database of clinical and imaging information of no less than 20,000 cases of elderly subjects. Some data is derived from the pre-established database (>12,000 cases) in cooperative research centers, while additional data will be collected from the newly established prospective follow-up database. Investigators performed noninvasive high-frequency ultrasound to detect arterial vascular structural changes, vascular dynamics and other indicators based on the existing database and the newly established imaging database to explore the characteristics of carotid atherosclerosis changes and ultrasound monitoring methods in the elderly. Finally, investigators integrated clinical and multimodal noninvasive imaging information to construct a noninvasive imaging-based intelligent risk assessment system for CHD and stroke. Primary endpoint was the cardiovascular-complex endpoint event,including myocardial infarction, cardiovascular death, resuscitation with cardiac arrest, revascularization, and stroke. Secondary endpoint was vascular lesion progression, including increase of vascular intima thickness, increase of vascular media thickness, plaque progression, and increase of vascular stenosis. All enrolled patients were followed up every six months to record whether the primary endpoint and secondary endpoint events occurred and to record the time and type of occurrence.
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).
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 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.
