Colocalization of Intracoronary Lipid-Rich Plaques and Calcifications: An Integrated NIRS-IVUS Analysis.

Atherosclerotic plaques consist of various components, including lipids and calcium. Although high lipid content has been associated with increased plaque vulnerability ([1][1]), calcifications, depending on their size, have been related to both plaque stabilization and vulnerability ([2][2]). Both
