Figure 1.

 Diagram of a section of a stented artery. Ninety nine sections from stented porcine coronary arteries displaying stretch (but not deep injury) containing a total of 1000 struts were analysed. Highly significant associations were found, by analysis of variance (ANOVA), between neointimal thickness and, in rank order: strut protrusion, inter-strut distance (ISD), medial bowing, strut depth, angular burden (AB), and strut thickness. No association was found with the number of struts in the section or with the major or minor axis measurements.
