Key result
Hypertension significantly reduced baroreflex sensitivity compared to normotension in elderly subjects (e.g., Valsalva: 1.9 and 2.8 vs 4.4 ms/mm Hg; P<0.05), regardless of hypertension type.
Why the study?
Does hypertension type (combined vs isolated systolic) affect baroreflex sensitivity in elderly subjects compared to normotension?

Reduced baroreflex sensitivity in elderly hypertension is independent of type; leaves open causal links to outcomes and intervention targets.

Does hypertension type (combined vs isolated systolic) affect baroreflex sensitivity in elderly subjects compared to normotension?
p-value: p=<.05
In elderly subjects, baroreflex sensitivity is reduced by elevated systolic blood pressure regardless of diastolic blood pressure levels.
James et al. (1996) conducted a cross-sectional in Hypertension (n=54). Hypertension vs. Normotension was evaluated on Baroreflex sensitivity (p=<.05). Hypertension significantly reduced baroreflex sensitivity compared to normotension in elderly subjects (e.g., Valsalva: 1.9 and 2.8 vs 4.4 ms/mm Hg; P<0.05), regardless of hypertension type.
