Comparative histological and morphometrical studies into the relevance of intimal thickening to coronary sclerosis.
It was found by comparative histological and morphometrical studies, carried out on 125 human hearts of different age (20-90 years) and sex, that there exist critical limiting ranges of intima thickness and the intima/media relationship (IMR) for diffuse intimal thickening and the preatheroma phase of arteriosclerosis. Since furthermore a maximum and a minimum intima thickness as relating to diffuse intimal thickening could be determined, it is assumed that the location and formation of arteriosclerotic plaques is determined by the degree of so-called diffuse intimal thickening. It follows from these findings that postnatal intimal proliferation represents a potential prearteriosclerotic lesion of the intima, and that progressive intimal thickening supports the arteriosclerotic alteration of the intima, leading, through an extensive necrosis of the intima, to the atheroma phase.
