Is heart disease a bigger threat to women than cancer?

Yes. Cardiovascular disease is the leading cause of death in women and takes more lives than all cancers combined, including breast cancer. About one in three women's deaths is cardiovascular. Despite this, only about half of women recognize it as their top health risk, which is part of why it is under-treated. It deserves the same attention women give to cancer screening.

Heart Disease in Women: Why It's Different and Often Missed | Philadelphia

TL;DR30-second take

Cardiovascular disease is the leading cause of death in women, killing more women than all cancers combined, yet it is under-recognized and undertreated. The old idea that women have only vague, atypical heart symptoms is misleading: chest pain is the most common heart-attack symptom in women, as in men, though women more often have additional symptoms like shortness of breath, nausea, or jaw and back pain that get blamed on something else. Women also carry risk factors men do not, including a history of preeclampsia or gestational diabetes, early menopause, and PCOS, and the menopause transition itself raises cholesterol and moves fat to the belly. The tools that prevent heart disease work in women too; the problem is that women are less likely to get them. The message is to know your numbers and take symptoms seriously.

TL;DR: Cardiovascular disease is the leading cause of death in women, killing more women than all cancers combined, yet it is widely under-recognized and undertreated. The old teaching that women get only vague, atypical symptoms is misleading and dangerous: chest pain is the most common heart-attack symptom in women, just as in men, though women more often also have shortness of breath, nausea, or jaw, neck, and back pain that gets blamed elsewhere. Women also carry risk factors that men do not, including a history of preeclampsia or gestational diabetes, early menopause, PCOS, and autoimmune disease, and the menopause transition itself raises cholesterol and moves fat toward the belly. Certain conditions, like small-vessel disease and spontaneous artery tears, strike women more than men and are often missed. The prevention tools all work in women; the core problem is that women are less likely to receive them. The takeaway: know your numbers, treat your history as risk information, and never let a cardiac symptom be waved away.

The leading killer, hiding in plain sight

Most people picture heart disease as a man's problem. It is not. Cardiovascular disease is the number one cause of death in women, taking more lives than all cancers combined, including breast cancer. About one in three women's deaths is cardiovascular. And yet surveys find that only about half of women recognize it as their leading health threat, and both women and their doctors are slower to suspect the heart when a woman has symptoms.

That under-recognition carries through to treatment. Women who qualify for cholesterol-lowering therapy are less likely than men to be prescribed a statin, less likely to get it at the recommended intensity, and less likely to be referred for testing, procedures, or cardiac rehabilitation after a heart event.¹ The gap is not that the treatments work less well in women; they work just as well. The gap is that women are less likely to get them.

The symptom myth, corrected

For years, women were taught that their heart attacks feel different, that they get vague, atypical symptoms rather than chest pain. That teaching has done harm, because it leads women, and emergency staff, to dismiss the very symptom that matters most.

Here is the accurate picture. Chest pain or discomfort is the most common heart-attack symptom in women, just as it is in men. In a large study of younger adults having heart attacks, chest pain was present in about 87% of women and 90% of men, a small difference rather than a categorical one.² What differs is that women more often have additional symptoms alongside or around the chest pain: shortness of breath, nausea or vomiting, pain in the jaw, neck, or back, unusual fatigue, or lightheadedness. Those extra symptoms, and a tendency to attribute them to stress or indigestion, are part of why women's heart attacks get missed.

The practical lesson is the opposite of the myth. A woman with chest pain should take it seriously rather than assume that because it is chest pain it cannot be her heart. And a woman with the associated symptoms, even without dramatic chest pain, deserves to have her heart considered rather than dismissed.

Risk factors unique to women

Beyond the standard risk factors that affect everyone, women carry several that are specific to them, and that are often overlooked because they show up long before heart disease does. These are best thought of as risk-enhancing factors: they refine a woman's risk and can justify earlier or more aggressive prevention.

The most underused is pregnancy history. Preeclampsia, gestational diabetes, gestational high blood pressure, and preterm birth all mark a higher lifetime risk of cardiovascular disease.⁴ A woman who had preeclampsia decades ago carries information her cardiologist would want, yet it is rarely asked about. Early or premature menopause, before about age 40 to 45, is another recognized risk enhancer, as is polycystic ovary syndrome. So are the autoimmune and inflammatory conditions that fall more often on women, like lupus and rheumatoid arthritis, whose chronic inflammation accelerates artery disease. And treatment for breast cancer, including chest radiation and certain chemotherapies, can injure the heart, which is why cardio-oncology has become its own field.

None of these guarantees heart trouble. What they do is add to the risk picture, and knowing them lets a physician start prevention earlier in a woman who would otherwise look low-risk on a standard calculator.

The menopause window

Menopause is more than a reproductive milestone; it is a cardiovascular one. As estrogen falls during the menopause transition, a woman's cardiovascular risk begins to accelerate, and part of that is driven by the transition itself rather than by aging alone.

The clearest changes are in cholesterol and body composition. LDL cholesterol and ApoB, the particle count that best predicts heart risk, tend to rise across the transition, and body fat redistributes from the hips toward the abdomen, the more dangerous, metabolically active pattern.³ Blood pressure and blood sugar often worsen too, though those track more with aging than with menopause specifically. The upshot is that the years around menopause are a window when risk climbs, and a good time to measure ApoB and, once in a lifetime, Lp(a), and to act on what they show.

One question always comes up here: does hormone therapy protect the heart? The clear answer is no. Hormone therapy is not a heart-prevention tool. It is effective for menopausal symptoms, and when started before age 60 or within about 10 years of menopause it appears safe for the heart in suitable women. But it is not approved or recommended for preventing heart disease, and guidelines advise against using it for that purpose.⁵ Treating hot flashes is a valid reason to consider it; preventing a heart attack is not.

Conditions that strike women more

Some forms of heart disease are more common in women and are easy to miss because they do not fit the classic picture of a clogged artery.

One is trouble in the heart's small vessels. Women more often have chest pain or even heart attacks with coronary arteries that look open on an angiogram, a pattern driven by dysfunction in the tiny vessels that a standard catheterization cannot see. Being told the arteries are clear can leave a woman without answers even though the problem is genuine. Another is spontaneous coronary artery dissection, or SCAD, a sudden tear in an artery wall that causes a heart attack, and that disproportionately strikes younger and pregnant or recently pregnant women who often have none of the usual risk factors. Both are increasingly recognized, but both are still frequently missed or mislabeled.

What to do about it

The message is not one of fear; it is one of agency, because the same prevention that protects everyone protects women, and women simply need to receive it. A few steps carry most of the value.

Know your numbers: ApoB or LDL, blood pressure, and blood sugar, plus Lp(a) checked once. Treat your history as data: tell your physician about any preeclampsia or gestational diabetes, early menopause, PCOS, autoimmune disease, or cancer treatment, because each can move the prevention timeline earlier. Take symptoms seriously, and insist your heart be considered rather than dismissed. And apply the proven tools without hesitation: statins and other cholesterol-lowering drugs, blood-pressure control, and the lifestyle foundation, all of which work as well in women as in men. A coronary calcium scan can refine risk in the borderline cases, with the caveat that a clear scan does not rule out the small-vessel disease or artery tears described above. The through-line is simple: women are undertreated rather than untreatable, and closing that gap starts with taking women's hearts as seriously as men's.

Guidance from the Clinic

"I see this gap constantly, and it frustrates me, because it costs women years. A woman comes in who had preeclampsia in her thirties, sailed through a standard risk calculator that ignores it, and is told she is fine, when that pregnancy history was a flare telling us to pay attention. My job is to fill in what the standard tools miss: I ask about pregnancies and menopause, I check ApoB and Lp(a), I take chest symptoms seriously instead of defaulting to anxiety as the explanation, and I treat women with the same proven drugs men get, because they work just as well. I also correct the old myth every chance I get. Women get chest pain when they have heart attacks. If a woman feels it, I want her to act on it rather than talk herself out of it. Heart disease is the thing most likely to take her life, and it is also one of the most preventable, if we stop overlooking it."

Key Takeaways

Cardiovascular disease is the leading cause of death in women, killing more than all cancers combined, yet it is under-recognized and undertreated compared with men.
Chest pain is the most common heart-attack symptom in women, as in men; the "women only get atypical symptoms" idea is a harmful myth, though women more often have additional symptoms that get dismissed.
Women carry risk factors men do not: a history of preeclampsia or gestational diabetes, early menopause, PCOS, autoimmune disease, and breast-cancer treatment all raise risk and justify earlier prevention.
The menopause transition itself raises LDL and ApoB and moves fat to the abdomen; it is a key window to check ApoB and a one-time Lp(a) and act, and hormone therapy is not a heart-prevention treatment.
Small-vessel disease and spontaneous artery dissection strike women more and are often missed; the fix is to know your numbers, share your full history, take symptoms seriously, and get the proven prevention women are too often denied.

Frequently Asked Questions

Common Questions

Mostly the same, with a twist. Chest pain or discomfort is the most common heart-attack symptom in both women and men. Women are somewhat more likely to also have shortness of breath, nausea, jaw or back pain, fatigue, or lightheadedness alongside it. The dangerous myth is that women do not get chest pain; they usually do. The important difference is that women's symptoms, and their chest pain, are more often dismissed.

Several. A history of preeclampsia, gestational diabetes, or gestational high blood pressure raises later heart risk, as do preterm birth, early menopause before about 40 to 45, and polycystic ovary syndrome. Autoimmune conditions like lupus and rheumatoid arthritis, which are more common in women, and treatment for breast cancer, also raise risk. These do not guarantee heart disease, but they are reasons to start prevention earlier, and they are important to tell your doctor.

Yes, and partly because of the transition itself, beyond aging alone. As estrogen falls, LDL cholesterol and ApoB tend to rise, and body fat moves toward the abdomen, both of which raise cardiovascular risk. This makes the years around menopause a key time to check your numbers and act on them. Hormone therapy can treat menopausal symptoms, but it is not a heart-disease prevention treatment and is not recommended for that purpose.

No. Hormone therapy is effective for menopausal symptoms like hot flashes, and when started early, before age 60 or within about 10 years of menopause, it appears safe for the heart in appropriate women. But it has not been shown to prevent heart disease, and major guidelines recommend against using it for prevention. If you are considering hormone therapy, do it for symptom relief, with heart safety as a consideration, and rely on the proven tools for heart protection.

Deep-Dive Questions

Several forces stack up. The cultural image of a heart attack is a middle-aged man clutching his chest, so women and clinicians alike are slower to think of the heart. The old "atypical symptoms" teaching made it worse, implying women's heart attacks are subtle when the most common symptom is the same chest pain men get. Women's symptoms are more often attributed to anxiety, stress, or digestion. Women were underrepresented in the research that shaped guidelines, so the evidence was built mostly on men. And some female-predominant conditions, like small-vessel disease and artery dissection, do not show up on the standard tests, so a woman can be told her heart is fine when it is not. The result is a chain of missed chances, each of which is fixable with awareness.

The heart is fed by the large coronary arteries that show up on an angiogram and also by a network of tiny vessels too small to image directly. In coronary microvascular dysfunction, those small vessels do not dilate properly, so the heart muscle can be starved of blood even when the big arteries look clear. This pattern is more common in women, and it explains why a woman can have genuine chest pain, or even a heart attack, and be told her arteries are normal. It is a genuine disease with genuine risk, and recognizing it, rather than dismissing the patient, is the first step toward treating it with the same risk-factor control used for large-artery disease.

It can underestimate you, yes. The common risk calculators were built largely on traditional factors and can miss the risk enhancers specific to women, such as a history of preeclampsia or early menopause, and they do not account for Lp(a) or for small-vessel disease. A woman can score low on the calculator and still carry meaningful risk that only shows up when someone asks the right questions and checks the right numbers. This is why a thorough prevention visit goes beyond the calculator, folding in your reproductive history, your ApoB and Lp(a), and, when useful, imaging, to build a truer picture than a formula alone can give.

The tools are the same; the application is more attentive. Prevention for a woman means taking a reproductive and menopausal history as seriously as a cholesterol number, measuring ApoB and a one-time Lp(a), using the menopause transition as a prompt to reassess risk, and being quicker to believe and investigate cardiac symptoms. The treatments, statins, blood-pressure control, and the rest, are identical and equally effective. The difference is vigilance: making sure a woman gets the same evaluation and the same proven therapy that a man with her risk would get, which today she often does not.
