Three intravascular ultrasound (IVUS) signatures have been associated with coronary artery disease instability: echo-attenuation, intraplaque echolucent zone, and spotty calcification. We sought to investigate the substrates responsible for these IVUS signatures in a relatively large series of postmortem human coronary samples. The exact mechanisms and pathologic correlates underlying echo-attenuation, an ...
