Does angiotensin II receptor blockade reduce tachycardia-induced atrial adhesion molecule expression?
AF and rapid atrial pacing both increase endocardial VCAM-1 expression, which can be attenuated by angiotensin II receptor blockade. This provides evidence that angiotensin II plays a pathophysiological role in prothrombotic endocardial remodeling.
These results demonstrate that in addition to eliciting peripheral insulin resistance, short-term CORT administration impairs insulin signaling in the rat hippocampus, effects that may contribute to the deleterious consequences of hypercortisolemic/hyperglycemic states observed in type 2 diabetes.
