Key result
Mental stress acutely increases BP and HR while reducing arterial compliance similarly across blood-pressure groups.
Why the study?
The role of tonic sympathetic stimulation on the properties of large arteries during mental stress in mild hypertensives was largely unknown.
Does mental stress differentially affect hemodynamics and arterial properties in individuals with mild hypertension compared to normotensives?
Comparison

Design

Similar acute hemodynamic responses to mental stress; leaves open whether baseline stiffness differences alter long-term vascular risk in hypertension.

Does mental stress differentially affect hemodynamics and arterial properties in individuals with mild hypertension compared to normotensives?
Mental stress induces similar acute hemodynamic and arterial changes in mild hypertensives and normotensives, though hypertensives exhibit chronic baseline differences in arterial stiffness.
Tsai et al. (2003) conducted a cross-sectional in Mild hypertension (n=42). Mental stress vs. Normotensives / Baseline was evaluated on Hemodynamics and central arterial wave reflection. Mental stress acutely increased blood pressure and heart rate and decreased arterial compliance similarly in mild hypertensive and normotensive individuals.
