Abstract
Intimal, longitudinal, band-like lesions and spiral sclerotic changes (Fig. 1) were reported as gross findings of a recent study of human coronary atherogenesis (Nakashima et al.); and a relationship of these band-like lesions to hemodynamic action of the blood stream against the coronary arterial walls was postulated. The present study concerns the macroscopic and microscopic observations of the early stages of the longitudinal lesions.
