Why the study?
Sympathetic vascular transduction and sympathetic and BP reactivity during a cold pressor test had not been comprehensively investigated in young healthy Black women.
Do young healthy Black women exhibit exaggerated sympathetic vascular transduction and BP reactivity during a cold pressor test compared to White women?
Do young healthy Black women exhibit exaggerated sympathetic vascular transduction and BP reactivity during a cold pressor test compared to White women?
Young, healthy Black women do not show altered sympathetic vascular transduction or exaggerated blood pressure reactivity to cold stress compared to White women, suggesting these mechanisms are not altered early in life.
Does not support early sympathetic dysregulation in young Black women; leaves open later contributions to racial hypertension disparities.
This study was the first to comprehensively investigate sympathetic vascular transduction and sympathetic and BP reactivity during a cold pressor test in young, healthy BL women. We demonstrated that young BL women do not exhibit exaggerated resting sympathetic vascular transduction and do not have augmented sympathetic or BP reactivity during cold stress compared with their WH counterparts. Collectively, these findings suggest that alterations in sympathetic transduction and reactivity are not apparent in young, healthy BL women.
