This uniquely illustrated atlas and text explains the evolution of atherosclerosis from initially minimal lipid deposits in the arteries of children, through histologically advanced but clinically silent lesions present in most younger adults, to lesion types that obstruct the vascular lumen and produce symptoms. To physicians and researchers, the volume offers a standard framework of histological morphologies of atherosclerotic lesions, providing a basis for correlation with morphologies determined by a variety of clinical imaging techniques and for recognizing changes in lesion progression, stabilization, or regression.
