Heart disease risk after menopause: the change nobody feels
Cardiovascular disease is the leading cause of death in women, and risk rises after menopause as the protective effects of oestrogen on blood vessels, lipids and blood pressure are withdrawn. Standard risk calculators have historically underestimated risk in women and omit several female-specific factors — early menopause, pre-eclampsia, gestational diabetes, polycystic ovary syndrome — that raise it. This is the single most valuable conversation to have at a midlife review.
What changes and why
Before menopause, women have lower cardiovascular risk than men of the same age. That advantage narrows across the transition and continues to narrow afterwards.
Several changes occur together: LDL cholesterol and apolipoprotein B rise around the final period, blood pressure rises as vessels stiffen and sodium handling changes, fat redistributes to the metabolically active visceral compartment, and insulin sensitivity declines.
Studies separating the effect of menopause from the effect of ageing find a distinct menopause-related component, particularly for lipids, rather than a smooth age-related trend.
The factors calculators miss
Risk calculators are built largely on data in which women were under-represented, and several recognised female-specific risk factors do not appear in them. All are worth raising explicitly because none will be asked about:
- Menopause before 45, or surgical menopause before the natural age
- Pre-eclampsia or gestational hypertension in any pregnancy
- Gestational diabetes
- Preterm delivery or a low birthweight baby
- Polycystic ovary syndrome
- Autoimmune conditions including rheumatoid arthritis and lupus
- Breast cancer treatment, particularly certain chemotherapy and radiotherapy
Why women's disease is missed
Women present with coronary disease differently more often than men do: pressure rather than sharp pain, discomfort in the jaw, neck or back, nausea, unusual fatigue for days beforehand, breathlessness.
Women also more commonly have coronary microvascular dysfunction, disease of the smallest vessels, which can cause genuine angina with normal-looking coronary arteries on standard imaging and is therefore sometimes dismissed.
Documented consequences follow: women wait longer before seeking help, are investigated less intensively, and are less likely to be treated to target for the same risk factors.
Hormone therapy and the heart
This is genuinely nuanced and should not be simplified in either direction. Hormone therapy is not prescribed for cardiovascular prevention.
What the evidence suggests is that timing matters: started in women under 60 or within ten years of menopause, hormone therapy does not appear to increase cardiovascular risk and may be associated with a favourable effect, while starting much later carries a different profile. Route matters too, with transdermal oestrogen not carrying the clot risk associated with oral.
It is a discussion with a clinician who knows your history, and the answer differs by individual.
When to see someone
Ask for a midlife cardiovascular review: blood pressure, a lipid profile, HbA1c and waist circumference, and bring the female-specific factors above to the appointment.
Call emergency services for chest pain or pressure lasting more than a few minutes, or with breathlessness, sweating, nausea, or pain spreading to arm, jaw, neck or back. Do not drive yourself.
