Key result
Older age in hypertensive men was associated with less pronounced postural falls in cardiac output (P<0.001) and stroke volume (P<0.001), and a smaller increase in heart rate (P<0.01).
Why the study?
Does age affect the hemodynamic response to a change in posture in nonelderly men with essential hypertension?
Cross-Sectional (n=110)
Does age affect the hemodynamic response to a change in posture in nonelderly men with essential hypertension?
p-value: p=<0.001
In nonelderly hypertensive men, older age is associated with smaller postural falls in cardiac output and stroke volume and a blunted heart rate increase, while peripheral vascular resistance control is preserved.

Suggests age-independent postural BP responses in uncomplicated hypertension; leaves open applicability to women and higher-risk patients.
Fagard et al. (1994) conducted a cross-sectional in essential hypertension (n=110). Older age vs. Younger age was evaluated on Postural changes in hemodynamic parameters (heart rate, cardiac output, stroke volume) (p=<0.001). Older age in hypertensive men was associated with less pronounced postural falls in cardiac output (P<0.001) and stroke volume (P<0.001), and a smaller increase in heart rate (P<0.01).
