Active clinical trials for "Coronary Artery Disease"

This registry is a clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). It is designed to investigate and collect clinical evidence for the clinical performance and safety of the Orsiro Drug Eluting Stent System in an all-comers patient population in daily clinical practice.

The purpose of this study is to evaluate medical cost-effectiveness, reduce the psychological risk factors( including hostility, anxiety, depression, and perceived stress) in coronary artery disease (CAD) patients and enhance the regulation of the autonomic nervous system (including respiration rate, heart rate, distal blood vessel pulse, and finger temperament) through web-based cognitive -behavioral group therapy.

To investigate whether instantaneous wave-Free Ratio(iFR)/Fractional Flow Reserve(FFR) guided treatment strategy makes the postulated treatment strategy by Coronary Angiogram(CAG) guide change and to analyze the cost-effectiveness of its dual diagnosis. To investigate difference between SYNTAX score evaluated CAG and functional SYNTAX score evaluated physiological assessment of coronary stenosis and its clinical effectiveness.

Clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). 500 subjects will be enrolled in this registry. The sample size maybe increased in order to reach the subgroup sizes (Diabetes, small vessel, AMI and CTO).

The objective of the study is to evaluate the safety and efficacy of XIENCE PRIME SV in real world practice in Japanese hospitals.

The purpose of this study is to describe the composition of bile acids and the gut microbiota comparing two populations: patients with coronary atheroma and the healthy subjects. Our hypothesis is based on the demonstration of the anti atherogenic and anti inflammatory effect of certain bile acids, and the role of the gut microbiota in the metabolic regulation.

In-stent restenosis is a major reason of coronary heart disease recurrence .Even in drug eluting stent(DES), Restenosis rate could be up to 10% in diabetes and complex lesions though it was about 3-5% in general. It is particularly important that in-stent restenosis after implantation was early diagnosed and detected. The evaluation of OCT imaging is more accurate for narrow area calculation, more clear for narrow organization structure and more specific for detecting tissue types.It is currently the best way for restenosis histologic diagnosis.But it has many weakness such as the higher cost,an invasive test, expensive instrument, relatively complicated to operate,and etc.In this study, OCT image was regard as the "gold standard" of stent restenosis. The improvement of spatial resolution of Gemstone CT can effectively improve the imaging quality and the measurement's accuracy of coronary artery stents.The diagnostic value of in-stent restenosis of Gemstone CT is higher than of the 320-detector row spiral CT. To a certain extent, the gemstone CT can replace OCT for examining the in-stent restenosis. This study will examine the degree of in-stent restenosis by the gemstone CT and the 320-detector row spiral CT and compare the two ways on the basis of the result of OCT.

To collect post marketing surveillance data on patients receiving at least one Combo Bio-Engineered Sirolimus Eluting Stent when used according to the Instructions for Use. Data will be collected in order to assess the long term safety and performance of the Combo Stent in routine clinical practice.

The prevalence of cardiovascular disease is rising; new methods must be created to assess the cardiovascular status of patients. If cardiovascular disease can be predicted, it may facilitate prevention. An association between periodontal disease and cardiovascular has been established, but a definitive mechanism is not understood. A good first step in finding that mechanism is to look at the correlation between periodontal disease and cardiovascular disease, both of which have an inflammatory component. This study observes the level of cardiovascular disease in patients and correlates it with the presence and degree of periodontal pathogens.

The investigators propose to correlate 1) cardiac MRI pericardial adipose volume, 2) the presence of pericardial monocytes and 3) circulating immune biomarkers in persons with and without CHD and HIV infection compared to seronegative controls with known CHD. The investigators aim to test the hypothesis that higher amounts of pericardial fat deposition and increased presence of monocytes within this adipose tissue are associated with underlying coronary artery disease in persons with HIV infection as measured by cardiac MRI.
