Key result
In healthy males, the muscle sympathetic nerve activity (MSNA) response to arousal strongly correlated with MSNA responses to mental stress (r = 0.80, P < 0.001).
Why the study?
Does the muscle sympathetic nerve activity response to arousal predict neurovascular reactivity during mental stress in healthy males?

Arousal MSNA response may predict mental stress reactivity in healthy males; leaves open extension to patients or interventions.

Does the muscle sympathetic nerve activity response to arousal predict neurovascular reactivity during mental stress in healthy males?
Effect estimate: r = 0.80
p-value: p=< 0.001
In healthy males, the muscle sympathetic nerve activity response to a brief arousal stimulus predicts sympathetic and blood pressure responses to sustained mental stress.
Donadio et al. (2012) conducted an observational in Healthy (n=30). Arousal response (MSNA inhibition) vs. Non-responders was evaluated on Correlation between MSNA responses induced by arousal and by mental stress (r = 0.80, p=< 0.001). In healthy males, the muscle sympathetic nerve activity (MSNA) response to arousal strongly correlated with MSNA responses to mental stress (r = 0.80, P < 0.001).
