A study in JACC: Cardiovascular Imaging found that an improved optical coherence tomography imaging method may help cardiologists predict future heart attacks by distinguishing life-threatening coronary plaques from less-dangerous ones. Researchers evaluated coronary atherosclerotic plaque properties in 30 patients with coronary artery disease and found that "intravascular polarimetry may open new avenues for studying plaque composition and detecting high-risk patients," researcher Brett Bouma said.
