Filter by:The goal of the proposed pilot study is to determine which method can detect myocardial ischemia at the predefined timepoints during endo-CABG. Additionally, the investigators want to examine the influence of mechanical ventilation on the occurrence of myocardial ischemia in patients undergoing endo-CABG.
Today, MRI is the gold standard for the precise assessment of left ventricular volume and function, but presents the drawback of having a long acquisition time and of generating motion artifacts, in particular respiratory artifacts, requiring repeated sequences in apnea to cover the whole cardiac volume. These apneas are difficult to achieve in patients with ischemic heart disease and may lead to degradation of the images, an increase in the duration of the examination by repeated acquisitions and therefore to diagnostic inaccuracies. Artificial intelligence, already used in practice in cardiac MRI for automatic segmentation of the heart chambers, improves radiological interpretation with rapid and precise measurements. Deep-learning, which is part of artificial intelligence, would allow the reconstruction of cine-MRI sequences in free breathing, in order to overcome the artifacts from respiratory motions, and the improvement of diagnostic performance while improving examination conditions for patients. Patients coming for a cardiac MRI for the assessment of ischemic heart disease will be eligible to the protocol. If the patient agrees to participate, a free-breathing cardiac cine-MRI sequence with Deep Learning based image reconstruction will be added to the usual protocol. No follow-up will be required in this study.
In addition, studies have found that indobufen can inhibit coagulation function in rats. Compared with aspirin, the duration of antiplatelet efficacy of indobufen was shorter, and the platelet function recovered completely 24 hours after drug withdrawal. However, there are few studies on the antiplatelet efficacy of indobufen. The investigators' previous study found that the inhibitory effect of indobufen 100 mg Bid on COX system in atherosclerosis or healthy volunteers was equivalent to that of aspirin 100 mg QD, but the inhibitory effect on platelet COX-1 channel was significantly weaker than that of aspirin 100 mg QD. In view of this, this study intends to investigate the antiplatelet effect of indobufen 200 mg Bid in patients with coronary atherosclerosis by comparing it with conventional-dose aspirin 100 mg QD.
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.
The CAREPATH will conduct Technical Validation and Usability (TVU) study by involving ≥ 45 target end users (16 patients with MCI or mild dementia with their informal caregivers and 16 healthcare professionals from various disciplines) and Clinical Investigation (CI) study involving ≥ 200 patients (≥ 100 users to pilot the CAREPATH platform and ≥ 100 patients as reference cases). Both of these pilot studies will be coordinated in four European countries (Spain, Romania, Germany and UK) with diverse health and social care systems, ICT landscape/digital maturity of healthcare provision and dementia national programs, which will allow for strengthening the evidence base on health outcomes and efficiency gains. The CAREPATH outcomes can be summarized as: 1. An Integrated Care Platform that jointly addresses multimorbidity, dementia and diminished intrinsic capacity and optimally manages healthcare interventions for its users (patients, informal caregiver, healthcare providers, etc). 2. Technical Validation and Usability (TVU) study involving over 45 users and Clinical Investigation (CI) involving over 200 patients that will be conducted in four European countries (Spain, Romania, Germany and UK) during two years and mobilizing the other necessary actors, such as caregivers and healthcare professionals, for the validation of healthcare interventions. 3. Dementia / Multimorbidity Guidelines that will be conceived for best healthcare delivery. 4. Health Economics Impact Assessment for healthcare cost effectiveness and care provision equalities. The incremental cost-effectiveness and the incremental cost-utility ratio would allow revealing the incremental cost (or the potential savings) per unit of benefit of switching from usual care to CAREPATH-an integrated patient-centred approach- in multimorbid elderly patients with dementia, and therefore, to determinate whether the CAREPATH approach would be considered as a cost-effective alternative.
The purpose of this study is to investigate the prognostic implication of pre-percutaneous coronary intervention (PCI) focal or diffuse disease patterns combined with post-PCI quantitative flow ratio (QFR).
To evaluate the efficacy of drug-coated balloon versus drug-eluting stent for the treatment of large de novo coronary lesions(RVD=2.75~4.0mm).
Coronary bifurcation lesions are lesions (or blockages) that occur at or near the intersection of a major coronary artery and one of the arteries' side branches. Numerous techniques and devices have been developed to treat coronary bifurcations; however, these types of lesions remain some of the most challenging, both in terms of procedural success and outcome. This study is designed as an observational, multi-center registry that will collect information on treatment strategies and outcomes of consecutive patients undergoing percutaneous coronary interventions (PCI) in coronary bifurcations among various participating centers, in order to determine the frequency of bifurcation PCI, the procedural strategies utilized, and the procedural outcomes.
Coronary angiography and percutaneous coronary intervention (PCI) is often performed in patients with ischemic heart disease. The safety of PCI has improved with new devices and strategies, but complications still occur, especially during complex procedures. The objectives of this multi-center observational registry are to examine frequency of complications occuring during cardiac catheterization and PCI, examine procedural strategies utilized for complication management, and evaluate the clinical outcomes (both immediate and during follow-up.)
Our study focuses on the question about primary cardiac rehabilitation (CR) patients with coronary heart disease are concerned about demonstrating the association between the patients' view of CR and social associated factors. In our study, all participants are invited to choose at least 1 question in 15 questions or provide their questions regarding their doubt about the CR after filling in their personal information. The selectable questions can be categorized into five titles: the content or purpose of CR, the method of CR, the advantage of CR, the adverse effect of CR, and the expenditure of CR.
