Cardiovascular Risk Doubles During Perimenopause
Women in perimenopause are twice as likely to have poor cardiovascular health as women who have not yet begun the transition. This is not a post-menopausal problem. It starts in the middle of it.
Menopause receives considerable attention, but the period leading up to it, perimenopause, is frequently overlooked. During this phase, hormone levels fluctuate sharply, menstrual cycles become irregular, and the body adjusts to declining estrogen levels. That adjustment affects far more than reproduction.
The study found that perimenopausal women scored significantly worse on cardiovascular health measures than premenopausal women of similar age. The elevated risk was adjusted for age, meaning the transition itself is the explanatory factor, not simply getting older.
Estrogen protects blood vessels
Estrogen has a protective effect on the vascular system. It keeps vessel walls flexible, regulates blood pressure, and suppresses inflammatory processes. As estrogen levels fall, these protective effects gradually disappear. That makes perimenopause a critical window for heart health, not a phase to wait out.
Women experiencing symptoms often wait years before cardiovascular risk factors are incorporated into their care. Yet the biological changes begin earlier than most clinicians assume.
Earlier monitoring as a strategy
The researchers call for earlier and more systematic measurement of cardiovascular health in women entering the menopausal transition. Blood pressure, cholesterol, and inflammatory markers should be standard components of perimenopausal care.
That also requires a shift in awareness among general practitioners and specialists. The transition is still too often framed as a reproductive issue. The new data show it is equally a cardiovascular issue, and that the clock starts ticking before menstruation stops permanently.
