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.
In patients with chronic coronary syndrome (CCS), clopidogrel has a class I/A indication in patients undergoing elective percutaneous coronary intervention (PCI). Although unproven, the possibility exists that clopidogrel does not yield an optimal platelet inhibition in multiple real-world scenarios that challenge current recommendations. The aim of this prospective observational study io assess in a consecutive unselected series of patients with CCS undergoing elective PCI the frequency of the following real world clinical scenarios: - No pretreatment at time of PCI ('naïve') - Evidence of incomplete responsiveness to clopidogrel - Indication to a complex PCI. We expect to demonstrate: - A not negligible proportion of patients with CCS are 'naïve' at time of elective PCI in clinical practice and require a rapid onset of P2Y12 inhibition. - A substantial proportion of patients with CCS who are treated with clopidogrel prior to elective PCI have high platelet responsiveness at time of the procedure. - A complex PCI is performed in a substantial proportion of patients with CCS.
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.
The primary objective of this study is to assess the accuracy in terms of sensitivity, specificity, negative and positive predicted values of the DL-based algorithm with respect to correct identification of the plaque and associated vulnerability grade.
The aim of this study is to determine if the test that allows males to achieve a higher VO2 (a measure of oxygen use during exercise) is different for females. The purpose of this study is to test 4 different exercise testing protocols to compare measured oxygen consumption in females and males with CAD (disease caused by the buildup of plaque in the artery walls which can lead to insufficient amounts of blood, nutrients and oxygen being supplied to the heart). The 4 exercise tests that will be completed on the treadmill are the modified Balke, modified Bruce, modified Naughton and University of Ottawa Heart Institute Slow Ramp protocols. Each test has a different stage duration (the amount of time that the test remains at a pre-determined speed and incline), and incremental increase in speed and incline. The main purpose of this study is to compare VO2 peak (the maximal amount of oxygen utilized during the exercise test) of females and males with CAD in 4 different exercise protocols. For example, the investigators will find out: 1. which exercise protocol is more likely to achieve a higher peak V̇O2 in females and which protocol is more likely to achieve a higher peak V̇O2 in males, 2. if enjoyment affects the duration of the test, and 3. how different exercise test protocols will provide different results of maximal oxygen used by the participant's body during the exercise test.
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.
The objective of this study is to evaluate the effectiveness and safety of Coroflex ISAR NEO stents in comparison to other drug-eluting stents (DES) in real-world practice.
Mortality rates after acute ischemic stroke remain high despite continuously improving treatment. In this context, it is important to note that a relevant portion of acute ischemic stroke patients die from adverse cardiovascular events, such as myocardial infarction, rather than from complications associated with the stroke itself. A possible reason might be that this patient group often suffers from at least moderate asymptomatic coronary artery disease. This study seeks to integrate cardiac computed tomography angiography into the standard-of-care diagnostic protocol of acute ischemic stroke. The aim of this prospective mono-centric trial is to enable accurate diagnosis of therapy-relevant coronary artery disease, other concomitant cardiac findings and cardiac causes of acute ischemic stroke, without delaying stroke therapy. In the long-run, the goal is to investigate whether cardiac computed tomography angiography and the resulting therapeutic measures (interventions or medications added) can improve functional outcome and rate of adverse cardiac complications in patients with acute ischemic stroke compared to a retrospective matched-cohort of patients without cardiac CT imaging.
Percutaneous coronary intervention for coronary bifurcation lesions represents one of the most challenging procedures in interventional cardiology because of lower angiographic success rate and increased risk of procedural complications. The study is designed to enroll 200 patients with acute or chronic coronary syndromes that meet the indications for intervention and with angiographic confirmed de novo Medina type 0,1,0 or 0,0,1 bifurcation lesion. In view of the potential risks of using DCB alone in the treatment of de novo bifurcation lesions, the following 2 treatment strategies are available. (1) DCB combined with provisional DES implantation 1-2 mm distally to the lesion ostium whenever this was required (DCB+pDES strategy). (2) DES implantation 1-2 mm distally to the lesion ostium followed by DCB (DES+DCB strategy). The primary endpoint was late lumen loss and major adverse cardiovascular events.
