Subclinical COronary Atheroscleorosis Updated With Coronary cT Angiography (SCOUT Study)
Coronary AtherosclerosisThe purpose of this study is to validate the usefulness of 64-slice multi-detecter computeted tomography as a screening tool in asymptomatic population.
Comparison Between Main Branch and Side Branch Vessels
Coronary Artery DiseaseThe purpose of this trial is to compare the clinical significance of the main vessel and the side branch vessel using EKG, pain score and coronary wedge pressure to develop a new scoring system to predict the clinical significance of a side branch
Clinical Application of MDCT in Coronary Artery Disease
Coronary Arteriosclerosis1) Establish normal value for coronary calcium scoring in Taiwan. 2) Find out the relationship of coronary calcium deposition and coronary artery stenosis. Propose a clinical management guideline based on coronary calcium score. 3) Evaluate sensitivity/specificity of coronary CT angiography and the influence of coronary calcium score on coronary CT angiography. 4) Evaluate the clinical application of myocardial enhancement measurement.
Clinical Observation of Coronary Arterial Microcirculation Dysfunction in Diabetic Patients With...
Complications of Diabetes MellitusCoronary Artery DiseaseThe purpose of this study is to investigate the prevalence and degree of coronary arterial microcirculaiton dysfunction of non- obstructive coronary artery disease in patients with type 2 diabetes. Furthermore, the risk factors of coronary arterial microcirulation would be screened and identified.
Non Invasive Extra-corporeal ECG Signal Analysis Algorithm( NID Algorithm) for Myocardial Ischemia...
Acute Coronary SyndromeMyocardial IschemiaThe NIA algorithm is similar to the traditional 12-lead ECG equipment. By analyzing patient data, NIA algorithm provides more detailed results compared to traditional 12-lead ECG. Patients with suspected coronary artery disease are conventionally diagnosed and treated by cardiac catheterization. However, cardiac catheterization is invasive procedure. Unless clinical diagnosis is evident before cardiac catheterization, a treadmill exercise test, a nuclear medicine myocardial perfusion test, or a multi-direction coronary CT angiogram is usually performed to increase the accuracy of diagnosis. But these examinations are not accessible to all patients, and are time-consuming and costly.
Prevalence of Chronic Kidney Disease and Its Association With Clinical Outcome in Patients With...
Coronary Heart DiseaseChronic Kidney DiseaseThis is a prospective, multi-center, hospital-based observational study. The aim of the study is to evaluate the prevalence of chronic kidney disease in patients with stable coronar heart disease.
Clinical, Physiological and Prognostic Implication of Microvascular Status
Coronary Artery DiseaseThere are several physiologic parameters in evaluating cardiovascular disease. This study will reveal which parameter is the most proper value in predicting disease severity and risk factors of patients.
Cardiovascular Epidemiology in Russian Federation

Preconditioning With Sevoflurane and Propofol in Patients Undergoing Minimally Invasive Mitral Valve...
Myocardial IschemiaThe main aim of this study is to compare markers of cardiac injury (Troponin I), inflammatory response and platelets function during minimally invasive mitral valve repair or replacement (MIMV) via right mini-thoracotomy in two standard anaesthetic regimes (sevo \propofol)
Association Between IVUS and OCT Parameters and Invasive Physiologic Indices
Ischemic Heart Diseaseto evaluate diagnostic accuracy and performance of IVUS and OCT-derived quantitative parameters to predict functional significance of stenosis defined using all the available physiologic indices. to explores the association between intravascular imaging-derived plaque characteristics and invasive physiologic indices.
