Filter by:At least 25 volunteers with a diagnosis of coronary artery disease in the Department of Cardiology of Dokuz Eylul University and who meet the criteria for follow-up and inclusion will participate in the study. Demographic and clinical information of the participants will be questioned. Active video games and exercise sessions will be randomized to last 25 minutes. Before and after the sessions, heart rate, blood pressure, shortness of breath, oxygen saturation and arterial stiffness will be measured. In addition, energy expenditure, heart rate, perceived exertion, shortness of breath and oxygen saturation will be recorded during the sessions. At the end of the sessions, the person will be asked if they enjoy active video games.
The use of pre-test probability (PTP) and coronary artery calcium (CAC) scores is guideline-recommended in the evaluation of coronary artery disease (CAD) and stable chest pain. The utility of these scores is population dependent. Previous studies have predominantly been limited to Western populations, despite Asia forming 60% of the global population. However, Asian populations have differing coronary artery phenotypes and may therefore have different PTPs with varying implications for risk stratification. Known difference in CAC implications support a global approach. Hence, this study aims to evaluate a contemporary PTP in diverse real-world Asian, Western and other cohorts and to evaluate the incremental value of CAC in predicting CAD and events. Primarily, the study will compare population specific PTPs and CAC for prediction of coronary computed tomography angiography (CTA) CAD. This could be compared with existing guideline-recommended PTPs alone or with consideration of risk factors or CAC. The study will also evaluate the accuracy of the prediction of major adverse cardiovascular events (MACE) using PTP models, risk factors and/or CAC. Lastly, the study will investigate the accuracy of zero CAC and other minimal risk tools to de-risk cardiovascular disease (CVD) in various populations. The study will investigate multiple international cohorts of patients referred for noninvasive testing using coronary CTA or other non-invasive imaging modalities. Locally-calibrated PTP models in consideration of risk factors or CAC will be separately tailored to each different cohort, and will be evaluated.
Magnetocardiography (MCG) is a non-invasive and accurate method of detecting myocardial ischemia. However, the previous MCG is limited in clinical practice due to its high working conditions and limited sensitivity. The next-generation MCG based on optical pumped magnetometer (OPM) has the advantages of high sensitivity, high reliability, high usability and low cost, which makes it suitable for most medical scenarios. Thus, this prospective single-center study aimed to use OPM MCG to explore its diagnostic efficacy and predictive value for myocardial ischemia. Participants who will receive coronary angiography examinations will be enrolled in this study. Participants enrolled in the study will also have a 1, 3, 6, 12, 24, 36, and 48-month follow-up for analysis of adverse cardiac events.
The goal of this prospective observational study is to learn about in patients who need percutaneous coronary intervention for coronary artery disease. The main questions it aims to answer are: - Fractional flow reserve according to coronary angiography findings after coronary artery balloon angioplasty - Differences in fractional blood flow reserve before and after lesions between coronary balloon angioplasty using a scoring balloon and a regular balloon Participants will voluntarily consent to the study after being fully informed about the study and given ample opportunity to ask questions.
Ischemia with non-obstructive coronary artery disease (INOCA) identifies a significant proportion of patients presenting with signs and symptoms of myocardial ischemia with normal or near-normal coronary arteries at angiography. Initially believed a benign condition, it is now well-established that INOCA is associated with an increased risk for cardiovascular events. However, it is rarely correctly diagnosed. The identification of distinct signatures of circulating biomarkers and platelet alterations associated with the specific endotype of INOCA (Microvascular Angina [MVA]; Vasospastic Angina [VSA]; both MVA and VSA; and none) may help in the diagnosis of these patients as well as in the identification of specific pathophysiologic pathways and the development of future therapies. In addition, the identification of specific signatures may help in the prognostic stratification of INOCA patients, identifying those that may need more aggressive therapy and closer follow-up. Finally, the results deriving from this study may pave the way for a new pathophysiology-driven approach with cause-target therapies personalized for the specific mechanisms of INOCA. The BIOPLATINO study is the first study specifically designed to evaluate if there is a unique signature of circulating biomarkers and/or platelet function tests able to discriminate between the multiple pathogenetic mechanisms of INOCA as well as the different clinical courses. Furthermore, it may pave the way for the identification of specific pathophysiologic pathways of INOCA and the development of future therapies.
This is a single center, randomized clinical trial (RCT), recruiting 200 patients with coronary artery disease (CAD) who are currently receiving standard care treatment at the cardiology department of Landspítali University Hospital in Reykjavik, Iceland. The RCT will determine whether an interactive health app that supports lifestyle changes can positively impact disease progression and quality of life of CAD patients. Patients will be randomized to receive either the standard of care (SoC) alone or SoC with the addition of the digital app. The digital app will include remote patient monitoring and a patient support program specific for CAD patients. The investigators will study the impact of the digitally delivered lifestyle intervention and remote monitoring on disease progression and on the patients' quality of life.
A multi-center, randomized, double-blind, placebo-controlled, parallel-group phase IV Study evaluating the effects of tirzepatide on atherosclerotic plaque progression assessed by coronary computed tomography angiography (CCTA) in participants with a diagnosis of type II Diabetes (T2DM) and atherosclerosis.
Atherosclerosis (deposition of a plaque essentially composed of lipids on the artery walls) is a frequent condition and is a leading cause of death worldwide. In addition to the long-established risk factors such as age, hypertension, diabetes or sedentary lifestyle, it has been demonstrated that immune cells can participate in the genesis of atherosclerotic plaques through metabolic and mitochondrial reprogramming. A non-invasive marker of this immune reprogramming has yet to be identified. Through the comparison of a group of atheromatous patients and a group of non-atheromatous patients, this study aims to evaluate this reprogramming phenomenon using a novel non-invasive method. This monocentric interventional study will take place at the Dijon Bourgogne University Hospital and will include 50 patients divided into 2 groups: "atheromatous coronary patients" and "non-atheromatous patients". The duration of participation in this study is 1 month. This study is based on usually performed procedures. Only blood samples will be taken on a catheter usually used during any cardiac surgery in addition to the medical care that is provided during hospitalization.
Multicenter, prospective, non-randomized, post-market clinical follow-up (PMCF) study to confirm and support the clinical safety and performance of Naviscore scoring balloon to meet EU Medical Device regulation (MDR) requirements in all the CONSECUTIVE patients treated with Naviscore.
The objective of this project is to validate, through high-throughput advanced metabolomics techniques, the nutritional assessment tools to be used in the IMPaCT cohort. At the same time, the ability of metabolomics fingerprints of nutritional patterns to discriminate between patients with and without major cardiovascular disease will be identified. Finally, the modification of these predictions will be evaluated based on the genetic profiles. The main hypothesis holds that the integration of metabolomics, genomic and nutritional information will serve to personalize the approach to cardiovascular disease, both in prevention and treatment, and that these tools, in turn, will be valid enough to be applied systematically and efficiently in the IMPaCT cohort.
