Why the study?
Does balloon injury combined with hypercholesterolemia enhance macrophage recruitment and endothelial dysfunction in rabbit iliac arteries?
Population
New Zealand White rabbits fed a 1% cholesterol diet or a standard diet for 14 weeks
Comparison
Balloon denudation of the left iliac artery 4… vs Control iliac arteries and standard diet
Design
Preclinical
Follow-up
4 weeks post-injury
Key result
Balloon injury combined with hypercholesterolemia caused intense macrophage infiltration, severe impairment of endothelial vasodilator function, and atypical endothelial morphology.

Supports hypothesis that hypercholesterolemia impairs post-injury endothelial healing; leaves open human translation and should not yet change practice.
Does balloon injury combined with hypercholesterolemia enhance macrophage recruitment and endothelial dysfunction in rabbit iliac arteries?
Balloon injury combined with hypercholesterolemia produces a diffuse inflammatory response, sustained impairment of endothelial function, and marked proliferative response in rabbit iliac arteries.
Weidinger et al. (1991) studied Arterial injury and hypercholesterolemia. Balloon denudation and 1% cholesterol diet vs. Standard diet and uninjured control arteries was evaluated on Vascular reactivity and structure. Balloon injury combined with hypercholesterolemia caused intense macrophage infiltration, severe impairment of endothelial vasodilator function, and atypical endothelial morphology.
