Filter by:The main goal of this clinical trial is to evaluate the feasibility of conducting a large-scale clinical trial testing a program containing several aspects for reducing the effects of air pollution on cardiovascular health (which is named the hybrid program hereafter) in adult patients (18 years or older) with atherosclerotic cardiovascular disease. Furthermore, we seek to answer how much patients adhere to and are satisfied with implementing the hybrid program, and what problems executing this program will bring for patients.
The aim of this research, proposed and funded by PlaqueTec and co-ordinated by Papworth Trials Unit Collaboration, is to demonstrate the performance of the coronary artery blood sampling device (Liquid Biospy System, LBS) and establish its usefulness to collect a range of disease biomolecules from the coronary artery of interest. Using the data generated from extensive analysis of the blood samples, key biomarker data will be generated that will close a knowledge gap and facilitate the development of tailored treatments for coronary artery disease.
The cardiorespiratory system integrates systemic and pulmonary circulation while ensuring adequate oxygenation of the body at rest and during exercise. In addition to chronic respiratory problems that mainly affect the lungs, airways and pulmonary vascular system, respiratory capacity and respiratory muscle strength can be negatively affected in a wide spectrum including cardiac diseases, surgeries, neuromuscular diseases, obesity, long-term bed rest, aging and inactivity. Weakness of the respiratory muscles causes important secondary consequences by causing the increased respiratory demands not to be met during physical activity. It has been reported that respiratory muscle training applied within the scope of pre-operative and post-operative cardiac rehabilitation program is beneficial in terms of increasing respiratory functions, reducing the risk of post-operative complications and length of stay. Respiratory muscle training is known to have many potential beneficial effects on patients undergoing cardiac surgery. Different methods and devices are used to improve and develop the functions of the inspiratory and expiratory muscles and each training method and device has differences. Therefore, it is thought that examining the clinical effects of using a personalized breathing exercise device on respiratory functions, respiratory muscle strength and functional capacity in individuals who have undergone cardiac surgery will contribute to the literature.
Teams of several medical professionals conduct high-risk cardiac surgical procedures. These professionals work in complex, stressful operating room environments requiring effective communication and teamwork skills. Surgeons, anesthesiologists, perfusionists, nurses, and surgical technicians working in this environment are also vulnerable to human errors. Non-technical skills for surgeons (NOTSS), defined as cognitive skills (situation awareness, decision making) and social skills (leadership, communication, and teamwork) underpinning medical knowledge and technical skills, are essential contributors to better cardiac surgery outcomes. Yet most of the surgical education programs focus only on technical skills, and interventions to improve the non-technical skills of cardiac surgical teams are scarce. The proposed research will develop and pilot-test and evaluate the preliminary effectiveness of an intervention to improve the non-technical skills of cardiac surgical teams.
This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.
Carotid plaque burden and composition features, particularly lipid necrotic core, are significantly associated with severity of CAD stenosis. This study aims to explore the relationship between various phenotypic patterns of carotid atherosclerosis with the prevalence, phenotype, and severity of coronary atherosclerosis. The patients with chest tightness or chest pain will receive carotid artery ultrasonography before coronary angiography so as to explore the relationship between them.
This is a prospective pilot study to evaluate the safety, tolerability and technical feasibility of utilizing carbon dioxide for assessing coronary blood flow in subjects with coronary artery disease.
Participants are being recruited at the inpatient department of the National Medical Research Center of Cardiology on a 'all-comers' basis. The enrolled participants will be divided into the main group (diagnosed with atherosclerotic cardiovascular disease (ASCVD)) and control (not diagnosed with ASCVD). The participants will have whole blood and serum collected at enrollment for further biobanking. A genome-wide association study will be carried out to determine the genetic determinants associated with atherosclerosis, coronary heart disease, acute coronary syndrome, etc., including a search for pathogenic variants.
The primary objective of this study is to determine whether a reduced radiation protocol (RRP) in which angiograms are acquired at ultralow radiation doses and then processed using spatiotemporal enhancement software can produce similar quality angiographic images as compared with standard techniques.
The primary objective of this study is to determine whether among symptomatic Peripheral Arterial Disease (PAD) patients with no known Coronary Artery Disease (CAD) who had undergone lower-extremity revascularization, a strategy of best medical therapy (BMT) plus selective coronary revascularization based on FFRct assessment of lesion-specific coronary ischemia can reduce adverse cardiac events and improve survival compared to BMT alone. Lesion-specific coronary ischemia is defined as FFRCT ≤0.80 distal to stenosis in a major (≥2 mm) coronary artery with severe ischemia defined as FFRCT ≤0.75.
