Key result
Menstrual cycle phases altered baroreflex control of heart rate, with preovulation sensitivities significantly greater than early follicular and midluteal phases, but similar to male volunteers.
Why the study?
Does the menstrual cycle phase alter baroreflex control of heart rate in healthy women compared to men?
Observational (n=28)
Does the menstrual cycle phase alter baroreflex control of heart rate in healthy women compared to men?
Baroreflex control of heart rate fluctuates across the menstrual cycle in healthy women, likely modulated by plasma estradiol levels, with preovulatory sensitivity matching that of men.
No takes yet. Share an insight, caveat, or question.
Menstrual phase may affect baroreflex assessments in women; leaves open whether estradiol modulation alters clinical autonomic evaluation.
Tanaka et al. (2003) conducted an observational in Healthy (n=28). Menstrual cycle phases and plasma estradiol levels vs. Other menstrual phases and male volunteers was evaluated on Cardiovagal baroreflex sensitivity. Menstrual cycle phases altered baroreflex control of heart rate, with preovulation sensitivities significantly greater than early follicular and midluteal phases, but similar to male volunteers.
