Filter by:In this study, the primary aim is to compare the impact of using a double-lumen tube and bronchial blocker for single-lung ventilation in patients undergoing minimal invasive cardiac surgeries on postoperative pulmonary functions. Secondary objectives include the comparison of application duration, success in lung collapse, and the number of repositioning attempts for both techniques.
Coronary CT angiography (CCTA) has been recognized as the first-line diagnostic test for most patients with suspected coronary syndrome, often acting as a gatekeeper for invasive coronary angiography. It is therefore pivotal to understand instances of discrepancies that are encountered in clinical practice. Moreover, most of the literature on this topic relies on obsolete machines or definitions of coronary artery stenosis that cannot be defined as severe. The investigators aim 1) to report the real word data on the performance of last-generation CCTA in identifying obstructive coronary artery disease (also considering different thresholds of stenosis, i.e., moderate or severe) and 2) to identify predictors of discrepancies.
The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
Coronary revascularization interventions such as coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are the standard of surgical treatment of patients with myocardial ischemia. However, up to 30% of patients experience complications of varying degrees within 12 months after the revascularization, or need for second intervention. Thus, it is necessary to search for additional approaches to the postoperative treatment of patients in order to improve the long-term results of revascularization treatment. Substances of natural origin with an anti-atherosclerotic effect have a good potential. These substances, as dietary supplements, can be taken by patients for a long time in conjunction with other prescribed medicines and treatments. Another valuable direction of investigations is the search for predictors of long-term cardiovascular complications after revascularization, which can be markers of inflammation and heteroplasmy levels of the patient's mitochondrial genome. The purpose of this study is to determine whether the intake of dietary supplement Allicor at a daily dose of 300 mg affects the frequency of long-term postoperative cardiovascular complications and re-intervention in patients after revascularization operations on the coronary arteries. The second goal is assessing the relationship between the grade monocytes inflammatory response and the level of heteroplasmy of the mitochondrial genome of blood leukocytes with the frequency of cardiovascular complications and re-interventions.
The purpose of the SIROOP Registry is to retrospectively and prospectively collect baseline, clinical and procedural characteristics of patients who have undergone PCI and are treated with either currently available sirolimus or paclitaxel coated DCBs (see Table 1), irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. Outcomes will be compared in different clinical subgroups. The impact of current DCBs in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
In this study the investigators retrospectively and prospectively collect information from enrolled subjects undergoing CCTA and evaluate the association of cardiac and non-cardiac imaging with laboratory markers and clinical data including outcome.
This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.
Markers of DNA damage and repair are present in both atherosclerotic plaques and peripheral blood mononuclear cells of patients with coronary artery disease. A positive correlation has been observed between the level of DNA damage and the severity of atherosclerotic lesions, as well as atherogenic risk factors such as smoking, hypertension and hyperlipidaemia. A number of in-vitro studies have implicated defective DNA repair in the development and progression of atherosclerotic lesions. In mouse models of atherosclerosis, the DNA repair signalling cascade has been shown to be amenable to pharmacological intervention and overexpression of specific repair proteins attenuate the development of atherosclerotic plaques. However, data regarding the role of DNA repair in the pathogenesis of atherosclerosis in humans are lacking. We have preliminary data indicating reduced DNA repair activity in patients with stable angina. This study will determine the molecular basis and the biological consequences of this observation.
Assessment of Change in AtheROSclerotic Plaque by Serial CCTA (ACROSS) is designed as a prospective observational study which aim is to demonstrate the effect of statins on coronary atherosclerosis, assessed by quantitative analysis of CCTA.
This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.
