The independent and add-on values of radial intima thickness measured by ultrasound biomicroscopy for diagnosis of coronary artery disease.
Carotid intima-media thickness (CIMT) has been widely used to risk stratify and predict coronary artery disease (CAD) despite its significant limitations. To test whether radial artery intima thickness (RIT) is closely associated with atherosclerotic risk factors, and whether RIT has an independent and additive value for diagnosis of CAD. ⋯ RIT could detect CAD independently similarly to CIMT. The add-on value of RIT to traditional risk factors for detecting CAD was superior to CIMT and addition of RIT and CIMT to traditional risk factors markedly increased the power to diagnose CAD. Thus, RIT measured by ultrasound biomicroscopy provided a novel approach to non-invasive diagnosis of CAD.
