Key result
Borderline hypertension is linked to higher SBP and delayed post-stress recovery despite normal stress responses.
Why the study?
Does mental stress elicit increased and prolonged psychophysiological responses in borderline essential hypertensives compared to normotensives?
Population
24 males, comprising 12 borderline essential hypertensives and 12 normotensives of the same age group.
Comparison
10-minute mental arithmetic stress test vs Normotensive control group undergoing the same…
Design
Case-control
Follow-up
16 minutes post-stress

Does not support stress reactivity hypothesis in borderline hypertension; leaves open whether delayed recovery contributes in observational data.
Case-Control (n=24)
Does mental stress elicit increased and prolonged psychophysiological responses in borderline essential hypertensives compared to normotensives?
The study finds no significant difference in the magnitude of stress responses between borderline hypertensives and normotensives, failing to support the reactivity hypothesis of hypertension.
Thomas Köhler (1996) conducted a case-control in Borderline essential hypertension (n=24). Borderline essential hypertension vs. Normotension was evaluated on Magnitudes of stress responses (SBP, DBP, HR, SCL, SF, A, NA). Borderline essential hypertension was associated with higher systolic blood pressure and delayed electrodermal recovery after stress, but stress response magnitudes did not differ from normotensives.
