No increased arterial stiffness after premenopausal risk-reducing salpingo-oophorectomy (RRSO).

Area of Science:

• Cardiovascular Disease Research
• Gynecologic Oncology
• Menopause Studies

Background:

• Women at high familial risk of ovarian cancer often undergo risk-reducing salpingo-oophorectomy (RRSO).
• RRSO induces surgical menopause, raising concerns about long-term cardiovascular disease (CVD) risk, though evidence is inconsistent.
• This study investigates CVD risk markers following premenopausal versus postmenopausal RRSO.

Purpose of the Study:

• To compare long-term CVD risk, specifically arterial stiffness, between women who had premenopausal RRSO and those who had postmenopausal RRSO.
• To examine the influence of the timing of premenopausal RRSO on arterial stiffness.
• To assess the association between arterial stiffness and coronary artery calcium (CAC) in women post-RRSO.

Main Methods:

• Cross-sectional study comparing premenopausal (≤45 years) and postmenopausal (≥54 years) RRSO groups.
• Arterial stiffness measured by pulse wave velocity (PWV), a predictor of CVD.
• Analyses restricted to women aged 60-70 to account for age differences; further subgroup analysis for premenopausal RRSO timing (≤41 vs 41-45 years).

Main Results:

• Women aged 60-70 with premenopausal RRSO showed significantly lower PWV compared to the postmenopausal RRSO group.
• The timing of premenopausal RRSO did not significantly impact PWV levels.
• In women with premenopausal RRSO, higher PWV was an independent predictor of the presence of CAC.

Conclusions:

• Premenopausal RRSO does not appear to have a long-term adverse effect on arterial stiffness.
• Increased arterial stiffness is associated with coronary artery calcium in women who have undergone premenopausal RRSO.
• Findings contribute to understanding the cardiovascular implications of RRSO in high-risk women.
