View clinical trials related to Extracranial Atherosclerosis.
Filter by:This study aims to compare the effectiveness and safety regarding treatment with standard anticoagulant only or adding antiplatelet to anticoagulant in patients with non-valvular atrial fibrillation and significant atherosclerosis including extracranial, intracranial, coronary or peripheral artery.
The goals of this trial are: 1. To compare the sensitivity and specificity of various tools including Doppler and magnetic resonance imaging (MRI) for diagnosing vertebral artery stenosis and carotid artery stenosis. The positron emission tomography (PET)/MRI fusion imaging will be a promising tool to provide both anatomical and functional imaging for vulnerable plaques. 2. To identify patients at high risk of plaque rupture by image studies, biomedical profile, and gene expression of circulating monocytes.
