Aortic mechanics remain unchanged during LBNP-induced sympathetic activation in healthy adults; leaves open its role in hypertension or vascular disease.
Does sympathetic stimulation induced by lower body negative pressure alter the mechanical properties of the abdominal aorta in healthy volunteers?
Sympathetic activation does not change aortic wall mechanics in healthy humans, suggesting that sympathetic modulation of aortic smooth muscle contractile activity is unimportant in blood pressure regulation.
Sonesson et al. (1997) studied this question.
