Association between Brachial Flow-Mediated Dilation and Calcium Score in Patients with Symptomatic CAD.

Background: Endothelial function plays an important role in the protection of vessels from atherosclerosis. Detection of endothelial dysfunction by non-invasive methods (flow-mediated dilation) and its association with other imaging modalities (calcium score in coronary computed tomography [CT] angiography) is still controversial. In this study, we aim to investigate the association between endothelial function evaluated by flow-mediated dilation (FMD) and calcium score evaluated by coronary CT.
