Active clinical trials for "Coronary Artery Disease"

To identify new cellular, metabolic, and genomic correlates of atherosclerotic plaque and early pathologic changes in the vascular wall and determine their consequences for coronary heart disease and stroke.

Elevation of plasma homocysteine has been recognized as one of the risk factors of atherosclerotic disease. The objectives of this study are: (1) to investigate the level of plasma homocysteine and the prevalence of hypehomocysteinemia (2) to find out the role of homocysteine in coronary artery disease and the proper cut-off point of plasma homocysteine to evaluate the presence of coronary artery disease; (3) to understand the control condition of tranditional risk factors of cardiovascular disease, especially hypertension, dyslipidemia, and diabetes mellitus. The study subjects were recruited from the ambulatory setting of cardiology in National Taiwan University Hospital.

Comparison study of myocardial perfusion SPECT imaging with current clinical use camera and new camera.

To determine whether there were differences in the prevalence and extent of atherosclerotic lesions in the coronaries and aortas between Alaskan natives and non-natives, and whether the extent of the lesions was related to omega-3 fatty acids in blood and tissues.

Using subjects from the Rochester Family Heart Study (RFHS), to characterize predictors of coronary artery calcification (CAC), a potent marker of atherosclerosis, among individuals from the general population.

To conduct a longitudinal study of central obesity and related risk factors found to be associated with hypertension and atherosclerotic cardiovascular disease (ASCVD) in a previously-examined cross-sectional cohort of second-generation Japanese Americans and in a newly-recruited cohort of third generation Japanese Americans.

To study the epidemiology of aortic calcium.

The goal of this multicenter prospective clinical cohort study is to investigate the impact of early use of low-dose Ticagrelor-based dual antiplatelet agent therapy (TDAPT) (ticagrelor 120mg daily; l-TDAPT) as compared to standard-dose TDAPT (ticagrelor 180mg daily; s-TDAPT) in outcomes of percutaneous coronary intervention (PCI). The main question it aims to answer are: Given the low ischemic risk and high bleeding tendency in Asians, the low dose TDAPT may provide better net clinical benefits of ischemic and bleeding events than the standard dose TDAPT.

The goal of this observational study is to study the non obstructive type of ischemic heart disease by identifying unique clinical features , frequency and age group .in patient admitted in coronary care unit , suffered from angina or heart attack. . The main question[s] it aims to answer are: how it different from classical type of ischemic heart disease ( obstructive coronary artery disease) what is frequency and age prevalence of these patient Participants evaluated by history , clinical examination, serum troponin and coronary angiography.

It is well documented in the literature that myocardial revascularization during valve surgery increases the risk of early mortality and morbidity. According to the most recent version of the European Guidelines, the possibility of myocardial revascularization via coronary artery bypass should be evaluated in patients with an indication for surgical treatment of heart valve disease but with coronary artery stenosis ≥ 50-70%. In this study, patients hospitalized for surgical heart valve disease, with occasional pre-operative finding of ≥ 50-70% coronary artery stenosis, without angina, are examined. After interdisciplinary discussion in the Heart Team, it was decided not to treat coronary artery disease during valve surgery. The aim is to evaluate the short and medium-term results of this "conscious omission".
