Women demonstrate more sustained increases in blood pressure following sympathetic bursts and less labile blood pressure during prolonged sympathetic quiescence compared to men.
Observational
Are there sex differences in beat-by-beat blood pressure responses to muscle sympathetic nerve activity?
Lower overall blood pressure in young women may be mediated by a lower frequency of sympathetic bursts rather than smaller beat-by-beat blood pressure responses to sympathetic outflow.
We demonstrate that during acute sympathoinhibition, women demonstrate more sustained increases in blood pressure following sympathetic bursts of activity than men. Likewise, during prolonged sympathetic quiescence, blood pressure is less labile in women than men. This suggests that lower overall blood pressure in young women may not be mediated by smaller beat-by-beat changes in blood pressure in response to sympathetic outflow but may instead be mediated by a lower frequency of sympathetic bursts.
Coovadia et al. (Fri,) conducted a observational in Blood pressure regulation. Female sex vs. Male sex was evaluated on Blood pressure response to sympathetic bursts of activity. Women demonstrate more sustained increases in blood pressure following sympathetic bursts and less labile blood pressure during prolonged sympathetic quiescence compared to men.
