Key result
Acute mental stress significantly increased ankle systolic blood pressure at 30 minutes post-task compared to a control task (interaction p<0.001) in young healthy men.
Why the study?
Acute mental stress increases arm blood pressure, but it remains unclear whether the stress-induced pressor response is also observed in other vessels.
Does acute mental stress increase ankle blood pressure in young healthy men?
RCT (n=56)
No
Does acute mental stress increase ankle blood pressure in young healthy men?
Acute mental stress induces a sustained elevation in both brachial and ankle blood pressure in young healthy men, suggesting a systemic pressor response.

May affect ankle BP interpretation after acute stress; hypothesis-generating for vascular reactivity studies.
Objective: Acute mental stress (MS) increases arm blood pressure (BP); however, it remains unclear whether the stress-induced pressor response is also seen in other vessels. The present study aimed to examine the impact of acute MS on ankle BP. Fifty-six young, healthy men (age range, 19–24 years) were divided into the MS (n = 29) and control (CON) (n = 27) groups, and each group performed a 5-min MS (mental arithmetic) or CON tasks. Systolic and diastolic BPs (SBP and DBP, respectively) of both the brachial and posterior tibial arteries were simultaneously measured at baseline and 5 and 30 min after the task.Results: In the MS group, brachial BP measures significantly increased (P < 0.05) until at 30 min after the task; ankle BP measures were also significantly (P < 0.05) elevated during this time. In the CON group, no significant change was found in brachial BP measures and ankle SBP, whereas a significant increase (P < 0.05) in ankle DBP was observed at 30 min after the task. Our findings suggest that not only brachial BP but also ankle BP exhibit a sustained elevation after acute MS, suggesting a systemic pressor response by stress exposure.Trial Registration: UMIN Clinical Trials Registry UMIN000047796 Registered on: 20th May 2022.

Kume et al. (2022) conducted an RCT in Healthy (n=56). Acute mental stress (mental arithmetic task) vs. Control task (counting upward) was evaluated on Ankle systolic blood pressure at 30 minutes post-task (p=<0.001). Acute mental stress significantly increased ankle systolic blood pressure at 30 minutes post-task compared to a control task (interaction p<0.001) in young healthy men.
