Filter by:ORBITA-MOON is a double-blinded, placebo-controlled experimental study that aims to understand how the different coronary artery stenoses contribute to overall clinical angina in patients with multi-vessel coronary artery disease. This study will investigate the symptoms conferred by each stenosis, induced by experimental ischaemia, for 60 patients with multi-vessel coronary artery disease.
This is a research study in minorities to compare the outcomes of two procedures that restore blood flow to the arteries of the heart. In one procedure the blockages are ballooned and then stented with a small wire mesh tube through a small incision in the wrist or the groin. The other procedure is an open-heart operation in which healthy blood vessels from inside the chest, leg, and/or forearm are used to "bypass" the blockages (like a detour). Outcomes will be measured by comparing survival and improvement in quality-of-life.

In the modern population, mortality and disability from cardiovascular diseases is predominant and is realized as a major medical and social problem. The study of mechanisms of development of age-related diseases, such as coronary heart disease (CHD), has demonstrated multiple qualitative and quantitative changes of metabolites in biological fluids of the body - blood, in the vascular wall, as well as in the tissues of vital organs. In routine clinical practice only about a dozen metabolic parameters are determined by standard laboratory methods. The proposed approach belongs to a new scientific direction , wich development is aimed at individualization of approaches to risk stratification of cardiovascular diseases and their complications. The data obtained in this project will allow to create a base of medical knowledge about spectral characteristics of blood serum, which most fully reflect the metabolic profile associated with atherosclerosis of coronary arteries. Researchers offer so-called multiplex diagnostics when multiple parameters of a biological object obtained by serum biochemical analysis and optical scattering analysis are used. Recognition of this big data is possible only by methods of mathematical analysis, which can take into account the degree of deviations, their directionality in each point of the spectral characteristic. Until recently, the standard setup for Raman light scattering studies had significant dimensions. The high cost of such installations made it difficult to widely use the method of optical spectroscopy for rapid analysis of medical objects. In recent years, the situation on the market of scientific instrumentation has changed radically, which allowed to significantly reduce and cheapen all components of Raman installations.This simplification and cheapening allows to bring optical research in medicine (optical biopsy) to a new level of use, directly into clinical laboratories. Novelty: This area of research belongs to high-tech and is very little represented in Europe. The prospect of using Surface Enhanced Raman spectroscopy (SERS) to determine subclinical lesions of coronary arteries and for risk stratification of diseases associated with atherosclerosis is quite unique and wasn't explored yet.
The aim of the study is to evaluate the clinical implications of artificial Intelligence (AI)-assisted quantitative coronary angiography (QCA) and positron emission tomography (PET)-derived myocardial blood flow in clinically indicated patients.
Atherosclerosis and its complications are a global problem. There are several widely known and proven risk factors that promotes atherogenesis in the majority of patients. However, significant proportion of apparently healthy and young patients with cardiovascular disease but yet without recognized atherogenesis promoting risk factors can be observed in clinical practice. It highlights the need of new risk markers for early atherosclerosis diagnostics to prevent serious cardiovascular complications in these patients and in population in general. The interest in the negative impact of genetic variance, gene regulation on atherogenesis is growing. Therefore the purpose of this study is to analyze the impact of genetic variance and microRNA expression on early atherosclerosis development in the population of young, apparently healthy patients with coronary atherosclerosis. The primary hypothesis is that the group of patients with premature atherosclerosis have common genetic variations promoting early atherosclerosis development. The secondary hypothesis is that specific circulating microRNA expression (miR-126, miR-145 and miR-155) correlate with plaque lipid core by near infrared spectroscopy (NIRS) analysis.
SATURATION is a prospective multicenter registry of consecutive patients who undergo coronary physiology testing using Pressure Wire X and Coroflow Coroventis Cardiovascular System software (Abbott Vascular, Abbott Park, IL, USA) and to assess the regional practice of patient selection, cardiovascular outcomes and additional procedures (stress testing, angiography, etc.) done after comprehensive invasive coronary physiology evaluation.
This study explores the effect of Internet based improved Baduanjin combined cross-theoretical model in family empowering cardiac rehabilitation for elderly patients with coronary heart disease after PCI, provides a scientific and reasonable case management plan for the rehabilitation of patients with coronary heart disease, and provides a reference for the development of scientific and refined cardiac rehabilitation case management suitable for elderly patients with PCI.
Peripheral artery disease, lack or blood flow to the legs, has a high prevalence in the Veteran population. In patients with severe peripheral artery disease that requires an endovascular or surgical intervention for lower leg revascularization, the long-term mortality of approximately 50% is worse that most cancers. The goal of this study is to develop a management strategy to improve cardiovascular outcomes in this high-risk peripheral artery disease population after lower extremity revascularization.
The purpose of the study was to further evaluate the long-term safety and efficacy of the Biolimus Coated Coronary Artery Balloon Dilation Catheter in the real world. The study population was patients with primary coronary vascular lesions with a blood vessel diameter of 2.0mm-2.75mm.
