ABSTRACT
For the 1st and 2nd pts.see ibid vol.11,no.4t p.241 & p.251 (1989).The anterior interventricular branch and the circumflex branch of the left coronary artery and the right coronary artery were excised from 7 autopsy adult subjects without heart diseases.A biaxial loading test lor the vascular specimens was completed,which was simultaneously finished in the internal thoracic artery (ITA) and the great saphenous vein (GSV) of the same subjects in order to compare with the coronary arteries.Elastic moduli of the vessels increased with increasing pressure in the vessels.As compared with GSV the mechanical properties of ITA ap-proach the coronary arteries.It is assumed that the coronary artery bypass grafting choose ITA before GSV in view of the mechanical properties of the vascular walls.A ratio of collagen per elastin may be used as an index of the arterial elasticity.It is discussed that the biomechanical properties of the arteries may influence the pathogenesis of the arteriosclerosis.
