Key result
In obese Zucker rats, peripheral microvascular dysfunction in chronic metabolic disease progresses in a retrograde manner, initiating at the postcapillary venular endothelium.
Suggests early venular targets in metabolic vasculopathy; leaves open clinical translation pending prospective validation.
Working from an established database spanning multiple scales and times, we studied progression of peripheral microvascular dysfunction in chronic metabolic disease. The data implicate the postcapillary venular endothelium as the initiating site for vasculopathy. Indicators of dysfunction, spanning network structures, hemodynamics, vascular reactivity, and perfusion progress in an insidious retrograde manner to present as functional impairments to muscle blood flow and performance much later. The silent vasculopathy progression may provide insight into clinical treatment challenges.

Halvorson et al. (2022) studied chronic metabolic disease in obese Zucker rats. chronic metabolic disease was evaluated on progression of peripheral microvascular dysfunction. In obese Zucker rats, peripheral microvascular dysfunction in chronic metabolic disease progresses in a retrograde manner, initiating at the postcapillary venular endothelium.
