Why the study?
Do older normotensive men exhibit a different sympathetic-hemodynamic balance compared to younger men?
Population
31 normotensive men (17 older men and 14 younger men)
Design
Cross-sectional
Key result
Older age in normotensive men was associated with a positive relationship between muscle sympathetic nerve activity and diastolic blood pressure (r=0.49; P=0.05), which was absent in younger men.

Does not inform hypertension management; leaves open whether compensatory balance fails with aging.

Do older normotensive men exhibit a different sympathetic-hemodynamic balance compared to younger men?
Effect estimate: r=0.49
p-value: p=0.05
Hart et al. (2009) conducted a cross-sectional in Normotension (n=31). Older age vs. Younger men was evaluated on Relationship between muscle sympathetic nerve activity and diastolic blood pressure (r=0.49, p=0.05). Older age in normotensive men was associated with a positive relationship between muscle sympathetic nerve activity and diastolic blood pressure (r=0.49; P=0.05), which was absent in younger men.
