Introduction: The risks of hypertension (HTN) and cardiovascular disease (CVD) rise dramatically in females around the typical age of menopause (TM; menopause age ≥46yr). Early menopause (EM; menopause age 0.05 for all. Further, cBRS and sBRS were similar between TM (cBRSup: 9.7±3; cBRSdown: 12.3±7; cBRStotal: 12.3±7ms/mmHg; sBRS: -2.7±1bursts/100Hb/mmHg) and EM (cBRSup: 8.7±4; cBRSdown: 11±5; cBRStotal: 10.4±4ms/mmHg; sBRS: -2±1bursts/100Hb/mmHg; p>0.05 for all). Conclusion: Contrary to our hypothesis, these findings suggest that EM may not influence BRS. These findings indicate that completing menopause early may not disrupt autonomic baroreflex function, suggesting that other mechanisms need to be explored to better understand the increased CVD risk in postmenopausal females who complete menopause prematurely or early.
