Menopause and Heart Health: Cholesterol, BP and Checks

You eat the way you always have. You walk the dog, you skip the second glass of wine. Then your annual blood work comes back and your LDL cholesterol has jumped. Or your blood pressure, always fine, is suddenly flagged.

If that has happened to you in your late 40s or 50s, it is not a personal failing. It is one of the quieter effects of menopause, and it is worth paying attention to.

Heart and blood vessel disease (cardiovascular disease) is the leading cause of death in women. A 2020 American Heart Association scientific statement concluded that the menopause transition is a time when heart risk speeds up, and that midlife is the window to catch it early (El Khoudary et al., Circulation 2020, PMID: 33251828).

The good news is in that word "early". These are numbers you can see, track and change.

The big US study that has followed more than 3,000 women through menopause since the 1990s (SWAN) could tell apart changes caused by age from changes caused by menopause itself.

Most risk factors, like blood sugar and inflammation, crept up steadily with age. But LDL cholesterol, total cholesterol and apolipoprotein B (ApoB) rose sharply in the year before and after the final period, faster than age alone explains, in every ethnic group studied (Matthews et al., J Am Coll Cardiol 2009, PMID: 20082925).

In plain terms: early postmenopausal women had about twice the odds of an LDL of 130 mg/dL or more compared with premenopausal women (Derby et al., Am J Epidemiol 2009, PMID: 19357323).

A quick word on ApoB. LDL tells you how much cholesterol is being carried. ApoB counts the particles carrying it, and particles are what lodge in artery walls. They usually move together, but ApoB can flag risk when LDL looks borderline.

Ask your clinician: "Can we repeat my lipid panel around the time my periods stop, and would an ApoB test add anything for me?"

Blood pressure. For many women it rises slowly through midlife. In about a third of SWAN women, systolic pressure (the top number) started climbing faster from about a year after menopause, and frequent hot flashes went with higher readings over time (Samargandy et al., Circ Res 2022, PMID: 35113663).

Body shape. You may weigh the same and still find your waistband tighter. In SWAN, the rate of fat gain doubled at the start of the transition while muscle began to slip, and that continued until about two years after the last period (Greendale et al., JCI Insight 2019, PMID: 30843880). Fat also moves toward the belly and around the organs, which matters more for the heart. Our menopause belly fat article digs into this.

Palpitations. A pounding, skipping or fluttering heartbeat is very common now. In SWAN, about half of women had a moderate or high chance of palpitations around the transition, and they were not linked to clogged or stiff arteries (Carpenter et al., Menopause 2023, PMID: 36256921). Still, palpitations with chest pain, fainting, breathlessness or a fast irregular pulse need prompt care.

You may have heard that estrogen is good for the heart. The trials tell a more careful story.

It is not a heart medicine. The US Preventive Services Task Force recommends against taking hormone therapy to ward off chronic conditions such as heart disease (a grade D recommendation; USPSTF, JAMA 2022, PMID: 36318127). That is about prevention. It says nothing against using HRT for hot flashes.

Timing changes the picture. In a closer look at the Women’s Health Initiative, women who started hormones within 10 years of menopause had about 6 fewer heart events per 10,000 women each year than placebo, while those starting 20 or more years out had 17 more. Stroke risk went up regardless of timing (Rossouw et al., JAMA 2007, PMID: 17405972).

Artery scans agree, with limits. In the ELITE trial, estradiol slowed thickening of the neck artery wall when started within 6 years of menopause but not 10 or more years later. Coronary calcium on CT did not differ (Hodis et al., N Engl J Med 2016, PMID: 27028912).

The fair summary: if you are healthy and within about 10 years of menopause, HRT for hot flashes does not appear to raise heart risk and may be neutral. It is still not a reason to start it for your heart. For women who have had a clot, a stroke or a heart attack, the calculation is different. See HRT after 60 and estrogen patch vs gel vs pill, since the route changes clot risk.

This article is general information, not medical advice. Decisions about starting, changing or stopping any prescription belong with a licensed clinician who knows your history.

Bring this list to your next appointment. You are not being difficult by asking:

1. A lipid panel, and a repeat around the time your periods stop. Ask whether ApoB would add anything.
2. Lipoprotein(a), once. It is mostly inherited and a high result changes how other risks are weighed.
3. Blood pressure at every visit, plus home readings if the clinic numbers are borderline.
4. HbA1c or fasting glucose, especially if your waist has grown.
5. A 10-year risk estimate that counts your full history. Preeclampsia, diabetes in pregnancy and menopause before 45 all raise risk in women and are often left off the chart.
6. An ECG if palpitations are new, persistent or come with dizziness or breathlessness.

If you would like your numbers before you go, see ordering your own blood work.

The same things that help at any age help now: regular brisk activity, strength training to hold on to muscle, not smoking, less alcohol, and meals built around vegetables, beans, whole grains, fish and olive oil. In large studies these habits are linked to better cholesterol and blood pressure.

Better sleep and fewer hot flashes may help too, since SWAN tied frequent hot flashes to higher blood pressure over time.

If lifestyle is not enough, statins and blood-pressure medicines are FDA-approved and have outcome data in women. Some people use fish oil for high triglycerides; our omega-3 page sets out the trials. For where you are in the transition, see the postmenopause overview and low estrogen symptoms.

One step this week: book the blood test. Knowing your numbers turns a vague worry into a plan.
