Background: Potassium-enriched diets exert renal and cardiovascular protective effects, but the underlying mechanisms are largely unknown.Methods: Using the dorsal skinfold chamber model for intravital microscopy, we examined endothelium-dependent vasorelaxation of precapillary resistance arterioles in response to acetylcholine or the NO donor SNAP in awake mice. Experiments were performed in...
