Hemodynamic and Sympathetic Nervous System Responses to Stress During the Menstrual Cycle
Why the study?
Does the menstrual cycle phase affect hemodynamic and sympathetic nervous system responses to stress in healthy premenopausal women?
Population
40 healthy premenopausal women, aged 26 to 51
Comparison
Luteal phase of the menstrual cycle vs Follicular phase of the menstrual cycle
Design
Cross-sectional

Implication
Menstrual phase may modulate stress responses; hypothesis-generating for cycle-adjusted BP assessment before hypertension diagnosis in premenopausal women.

P
Population
40 healthy premenopausal women, aged 26 to 51
I
Intervention
Luteal phase of the menstrual cycle
C
Comparator
Follicular phase of the menstrual cycle
O
Outcome
Hemodynamic (systemic vascular resistance, stroke volume, heart rate, cardiac output) and sympathetic nervous system (plasma catecholamine) responses to a battery of laboratory stressorssurrogate
Hemodynamic and sympathetic responses to stress are lower during the luteal phase compared to the follicular phase, suggesting blood pressure should be evaluated across different menstrual phases before diagnosing hypertension in premenopausal women.
