Should not change clinical practice; leaves open macrophage-driven mechanisms in human vein graft disease.
Does hypercholesterolemia increase intimal thickness and smooth muscle proliferation in rabbit vein grafts?
In a rabbit model, hypercholesterolemia increases vein graft intimal thickness primarily through macrophage accumulation rather than enhanced smooth muscle cell proliferation.
Zwolak et al. (1989) studied this question.
