Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to systematically evaluate the clinical application value of vascular endothelial function examination in patients with non-obstructive coronary artery disease.

Rationale: The interaction between nonvitamin K oral anticoagulants (NOACs) and platelet aggregation is complex. The direct activated factor X inhibitors (factor Xa inhibitors) an NOAC antagonizes thrombin generation, one of most important platelet agonist, so that, factor Xa inhibitors has a potential effect in decreasing thrombin-mediated platelet aggregation. On the other hand, patients who experience ACS continue to have a hypercoagulable state for long periods after the index event. The COMPASS trial showed that, in patients with stable coronary artery disease (SCAD), Rivaroxaban (a direct anti-Xa inhibitor) in addition to antiplatelet agent, compared to antiplatelet therapy alone, reduced the composite endpoint of myocardial infarction, stroke and death. Objective: Analyze the role of edoxaban on platelet aggregation in SCAD patients. Methods and Results: This is a prospective, non-randomized, interventional study of SCAD patients taking low-dose acetylsalicylic acid (ASA). Subjects initially will receive in the following sequence: ASA 100 mg once daily (QD) plus edoxaban 60 mg QD, clopidogrel 75 mg QD alone, clopidogrel 75 mg QD plus edoxaban 60 mg QD, and edoxaban 60 mg QD alone. Platelet function will be assessed by standard of care technology, at baseline and after each intervention phase, by Multiplate-ADP® (primary endpoint), Multiplate-Aspi® and Multiplate-TRAP®. In addition to immature platelets fraction (% IPF) and count (IPC). Coagulability will be assessed, at baseline and after each intervention phase, by thromboelastogram (TEG) assessment. Specifically, after the phases in which edoxaban will be administered activated factor X (FXa) level and Plasminogen activator inhibitor-1 (PAI-1) will be evaluated in addition to previous. Finally, inflammatory markers will be, at same way, assessed at baseline and after intervention each phase: ultrasensitive C-reactive protein (us-PCR). Keywords: edoxaban, direct factor Xa inhibitor, stable coronary artery disease, aspirin, clopidogrel, platelet aggregation.

Today, 50 % of cardiac patients do not participate in cardiac rehabilitation due difficulties in navigating and accessing rehabilitation activities. HeRTA is a partnership project involving Center for Clinical Research and Prevention (CCRP), Hvidovre Hospital, Rehabilitation Center Albertslund and Copenhagen (municipalities), the Danish Heart Association, and local sports associations. A patient advisory board participate throughout the project to ensure a continued focus on patient interests. The overall aim of HeRTA is to develop and test the feasibility of a new, sustainable model for rehabilitation supporting patients to take part in rehabilitation and promoting life-long activity for all patients with heart disease. To ensure equal access to rehabilitation some activities are open to all patients, while others are tailored specifically to patients with vulnerability. The project unfolds in three phases: Development (1. January 1. 2020 - 14. November 2021): Partners and patients co-create content and procedures; Feasibility (15. November 2021 - 31. July 2023): The feasibility of the model is tested, and promising components are identified; Long-term follow-up and implementation (1. August 2023 - 31. December 2025): Long term effects are investigated and promising components are tested in new settings. During the feasibility phase the investigators will examine whether the intervention activities are feasible, acceptable, and may have positive effects for patients with heart disease. The investigators use qualitative data on implementation and acceptability of intervention among partners and patients. An randomisered controlled trial (RCT) component will assess effects on patient participation rates, health, physical activity level, and life quality. Data is collected from practitioners and patients through focus groups, observations, field notes, questionnaires, and interviews. Results will point to: innovative ways to organize integrated rehabilitation pathways. approaches to ensuring rehabilitation targeted at patient needs.

This study is about testing whether exercise will improve fitness and lessen risk factors related to heart disease, diabetes, and obesity in Latina breast cancer survivors.

The POLARSTAR study is an early feasibility study to evaluate the performance and safety of the CryoTherapy System (CTS) for the treatment of coronary plaque lesions that are not obstructing blood flow but are at high-risk of rupture which would cause a major heart attack. The CTS is used to apply local freezing of the lesion using a balloon catheter, controlled by a console that regulates in- and outflow of a cooling agent into the catheter. The treatment is expected to stabilize the lesion, diminishing the risk of rupture. The study will enrol subjects with acute coronary disease who have suitable coronary lesions. Subjects will be followed for 1 year after the CTS treatment. Baseline identification of lesions will be done using Coronary CT-angiography (CCTA), which will be repeated at 3 and 9 months after procedure.

The objectives of this pilot RCT are to examine if the Talk Test is an effective and safe tool as compared with CPET for exercise prescription in patients who have undergone CABG or PCI and enrolled in a home-based CR program with virtual exercise training monitoring.

Older adults with coronary artery disease (CAD) have impaired vascular and inspiratory muscle function. The objective of this study is to examine the effect of beet juice supplementation on vascular and inspiratory muscle function in older adults with CAD.

The purpose of this study is to examine the effect of a brief electronic shared decision making (eSDM) intervention on depressive symptoms in coronary heart disease patients with elevated depressive symptoms.

This study proposes to develop an MRI technique named Coronary Atherosclerosis T1-weighed Characterization (CATCH) that will improve the quality and reliability of coronary atherosclerosis evaluation, as well as simplify the scanning process and significantly shorten imaging time compared with conventional imaging methods.

NOTACS aims to determine if prophylactic use of high-flow nasal therapy (for a minimum of 16 hours after tracheal extubation) increases days at home in the first 90 days after surgery, for adult patients undergoing cardiac surgery who are at high risk of postoperative pulmonary complications. The study also incorporates a health economic analysis to estimate the incremental cost-effectiveness and cost-utility of HFNT versus standard oxygen therapy at 90 days, from the view-point of the public sector, NHS and patients.
