Key result
Carotid artery stiffness is linked to lower sympathetic baroreflex sensitivity in elderly adults, particularly women.
Why the study?
Is barosensory artery stiffness associated with sympathetic baroreflex sensitivity in elderly men and women?
Cross-Sectional (n=61)
Yes
Is barosensory artery stiffness associated with sympathetic baroreflex sensitivity in elderly men and women?
Effect estimate: r=0.49 and 0.50
p-value: p=<0.05
Increased barosensory artery stiffness is associated with reduced sympathetic baroreflex sensitivity in the elderly, which may contribute to the higher prevalence of hypertension in elderly women.

Association between carotid stiffness and lower sympathetic baroreflex sensitivity in elderly; leaves open causal contribution to sex differences in hypertension.
Okada et al. (2011) conducted a cross-sectional in Healthy elderly individuals (n=61). Barosensory artery stiffness (carotid and aortic stiffness) was evaluated on Sympathetic baroreflex sensitivity (r=0.49 and 0.50, p=<0.05). Sympathetic baroreflex sensitivity was inversely correlated with carotid artery stiffness in both elderly men and women, with women exhibiting lower overall sensitivity.
