Key result
Baseline sympathetic nerve activity was positively related to wasted left ventricular energy (r = 0.79, P < 0.05) and augmented pressure (r = 0.69, P < 0.05) in postmenopausal women.
Cross-Sectional (n=39)
Effect estimate: r = 0.79
p-value: p=<0.05
The relationship between sympathetic nerve activity and aortic wave reflection shifts from inverse in young women to positive in postmenopausal women, potentially contributing to increased cardiovascular risk after menopause.
No takes yet. Share an insight, caveat, or question.
Leaves open whether inverse wave reflection–sympathetic activity link persists post-menopause; prospective studies needed.
Hart et al. (2013) conducted a cross-sectional in Postmenopause (n=39). Sympathetic nerve activity was evaluated on Correlation between baseline sympathetic activity and wasted left ventricular energy (r = 0.79, p=<0.05). Baseline sympathetic nerve activity was positively related to wasted left ventricular energy (r = 0.79, P < 0.05) and augmented pressure (r = 0.69, P < 0.05) in postmenopausal women.
