Filter by: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 observational study is to evaluate effect of total intravenous anesthesia or inhalation anesthesia on inflammatory biomarkers in coronary artery bypass surgery and their relationship with early postoperative complications. The main questions it aims to answer are - Does the type of anesthesia have a relationship with inflammatory biomarkers? - Are inflammatory biomarkers associated with postoperative complications?
Heart disease is the leading cause of death globally, accounting for 16% of the world's total deaths. The number of cases is expected to increase as our population ages. Heart disease also results in large economic burden. It costs the United States about $219 billion per year. Some patients have symptoms that aren't helped by drugs or other medical treatments. These patients will need a surgery that is called cardiac artery bypass graft (CABG) surgery. CABG helps to improve chest pain which is one of the most common complaints of heart disease, and has life-prolonging potential. A limitation of CABG is that it results in increased inflammation. These patients also report high levels of anxiety and depression. Depression and anxiety in the several days surrounding surgery are related to several important things. These include worse health outcomes, worse quality of life, increased risk of death, and increased health care cost. Acceptance and Commitment Therapy (ACT) is a kind of therapy. ACT is adaptable, easy to access, and effective in brief formats. ACT has been gaining evidence for its use in many patient samples. Few studies have used ACT with heart disease patients. No known studies currently exist that have used ACT within the few days surrounding CABG surgery. To address this need, the investigators will conduct a two-arm feasibility randomized control trial (RCT). Patients will be randomized to one of two groups. The first group will complete a brief, 2-session telehealth ACT intervention. The second group will be a control group. The control will consist of treatment as usual. The investigators will evaluate the feasibility of this brief ACT intervention delivered in the peri-operative period. The investigators will also examine preliminary efficacy of the ACT intervention. The investigators will examine anxiety, depression, psychological inflexibility, well-being, and cardiovascular health-related quality of life. The investigators will also examine the intervention's impact on inflammation by measuring two inflammatory markers. The results from this study will also lay the groundwork for larger or multiple site RCT studies.
The COMPLETE study is a single-centre, investigator-initiated study of patients with an indication for invasive coronary angiography with CCTA performed during the diagnostic evaluation. After identifying the presence of a coronary stenosis, defined as an epicardial lesion >50% stenosis on CCTA, patients eligible for the study will be invited to participate. The main aim of this trial is to assess the accuracy of coronary CT angiography to quantify total atheroma volume with intravascular ultrasound as reference. Patients will be divided into 2 sub-groups: Cohort 1: Patients with stable coronary artery disease or stabilized acute coronary syndromes with a clinical indication for invasive coronary angiography. Cohort 2: Patients previously revascularized with a metallic stent with a clinical indication for invasive coronary angiography. In both cohorts, patients should have undergone coronary CT angiography as part of the standard of care. Patients included in the study will be managed according to the standard of care for the assessment of coronary artery disease. Clinical follow-up will be collected until 3 years follow-up.
The CAD-MAP (Myocardial and Arterial Phenotype of Coronary Artery Disease) registry is initiated with the goal to describe the cardiac imaging map including epicardial coronary artery, coronary microcirculation and myocardium, and further exploring the prognostic value of multidimensional imaging biomarkers and predictive models in CAD patients.
This study aims to evaluate the safety and effectiveness of the CorVad Percutaneous Ventricular Assist System for short-term ventricular support during high-risk percutaneous coronary intervention (HRPCI) in non-emergent, hemodynamically stable coronary artery disease patients via a prospective, multicenter, single-arm clinical trial.
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.
