Key result
Heightened systolic blood pressure responses to mental arithmetic were associated with increased future systolic blood pressure at 1 year (Δ R2 = 0.045) after adjusting for baseline BP and risk factors.
Why the study?
Do cardiovascular responses to mental stress tasks predict future resting blood pressure in healthy Thai adults?

Do cardiovascular responses to mental stress tasks predict future resting blood pressure in healthy Thai adults?
Blood pressure reactivity to mental stress predicts future resting blood pressure in a Thai cohort, extending previous findings from Western populations to an Asian population.

Mental stress BP reactivity may forecast future elevation; hypothesis-generating and should not yet change practice.
Cardiovascular responses to mental stress tests have been related to future blood pressure ( BP ) levels. However, most studies have been completed in N orth A merica and E urope; only one study has been conducted in A sia. Therefore, the study explored whether cardiovascular responses to mental stress predict future resting BP in T hailand. Hemodynamic measures were obtained from 101 healthy adults before, during and after mental arithmetic, a speech task, and a cold pressor task. A follow‐up assessment of resting BP was undertaken 1 year later. Results showed that Thais responded to standardized mental stress tasks with large and significant cardiovascular reactivity. Regression analyses indicated that, after adjustment for baseline BP and traditional risk factors, heightened systolic blood pressure ( SBP ) responses to mental arithmetic were associated with increased future SBP (Δ R 2 = .045). These findings suggest that BP reactivity predicts future BP and may play a role in the development of hypertension. In addition, Thais displayed large cardiovascular responses to standardized mental stress tasks, of a similar magnitude to previous studies of N orth A mericans and E uropeans.

Yuenyongchaiwat et al. (2015) conducted a cohort in Healthy adults (n=101). Cardiovascular responses to mental stress tasks (mental arithmetic, speech task, cold pressor task) was evaluated on Future resting systolic blood pressure (Δ R2 = 0.045). Heightened systolic blood pressure responses to mental arithmetic were associated with increased future systolic blood pressure at 1 year (Δ R2 = 0.045) after adjusting for baseline BP and risk factors.
