We investigated in female rats the coronary response to infusion of angiotensin-II type 2 receptor agonist compound 21 (C21) utilizing high resolution SR microangiography. We found that in non-diabetic rats acute C21 infusion evoked dilation in the coronary microvessels that most likely involved endothelium derived hyperpolarization factors, while C21 evoked mild constriction in prediabetic rats.
