Acute local infusion of angiotensin II impairs microvascular and metabolic insulin sensitivity in skeletal muscle

摘要

Angiotensin II (AngII) is a potent vasoconstrictor implicated in both hypertension and insulin resistance. Insulin dilates the vasculature in skeletal muscle to increase microvascular blood flow and enhance glucose disposal. In the present study, we investigated whether acute AngII infusion interferes with insulin’s microvascular and metabolic actions in skeletal muscle.
