- Heart disease is the leading cause of death in women globally, yet it remains significantly under-recognised, under-investigated, and undertreated compared to men.
- Women’s heart attack symptoms are often less typical than the classic crushing chest pain, fatigue, breathlessness, nausea, and jaw or back discomfort are more common and more frequently attributed to other causes.
- Oestrogen has a protective effect on the cardiovascular system. Its decline after menopause marks a significant shift in women’s cardiovascular risk.
- Certain conditions are specific to or predominantly affect women, SCAD, peripartum cardiomyopathy, and takotsubo cardiomyopathy all deserve particular awareness.
- Pregnancy-related complications, including preeclampsia and gestational diabetes, are independent risk factors for future cardiovascular disease and should always be shared with your cardiologist.
For much of the twentieth century, cardiovascular disease was considered primarily a man’s disease. Clinical trials were conducted predominantly in male populations. Guidelines were built from predominantly male data. The classic image of a heart attack, a middle-aged man clutching his chest, dominated public understanding.
The consequence was that heart disease in women was studied less, recognised later, investigated less thoroughly, and treated less aggressively.
That understanding has changed substantially, but the gap it created has not fully closed. Women with heart disease are still more likely to have their symptoms attributed to anxiety or non-cardiac causes. They are still less likely to be referred for investigation at the same rate as men. And they still face a higher in-hospital mortality from heart attack, in part because of diagnostic delay.
Awareness is the most powerful tool available to close this gap.
Why Heart Disease in Women Is Different
A different disease pattern
Women tend to develop coronary artery disease a decade later than men, in part because oestrogen provides cardiovascular protection during the premenopausal years. But when it does occur, it can present differently, be harder to detect on standard testing, and carry different prognostic implications.
Women are more likely to have non-obstructive coronary artery disease, disease in the microvascular circulation rather than the large coronary arteries, which can cause genuine ischaemia and anginal symptoms but may be missed on a standard angiogram that appears normal.
This condition, known as INOCA (ischaemia with non-obstructive coronary arteries) or MINOCA (myocardial infarction with non-obstructive coronary arteries), is now recognised as an important and underappreciated cause of cardiac events in women.
Recognising a heart attack
The most critical practical point in women’s cardiovascular health is recognising heart attack symptoms. The classic presentation, central chest pressure radiating to the left arm, occurs in women too, but it is considerably less consistent.
Women presenting with heart attack more commonly describe unusual fatigue, shortness of breath, nausea, jaw pain or back pain, and a general sense of feeling unwell, without dramatic chest pain. These symptoms are more easily dismissed by the patient, by family members, and sometimes by clinicians.
The consequence of this diagnostic delay is measurable. Women with atypical symptoms spend longer in emergency departments before receiving an ECG and troponin, are less likely to be admitted to a cardiac unit, and are less likely to receive the same intensity of investigation and treatment as men presenting with typical symptoms.
The question I encourage every woman to ask is not “could this be serious?”, it almost always could be explained by something less concerning. The right question is “could this be my heart?” And if the answer is anything other than a confident no, get assessed. The ECG and troponin test will answer the question quickly.
The Role of Oestrogen
Protection before menopause
Oestrogen has well-documented cardiovascular protective effects in premenopausal women. It promotes vasodilation, improves the cholesterol profile by raising HDL and lowering LDL, has anti-inflammatory properties, and supports the health of the endothelium, the inner lining of the arteries.
The menopause transition
After menopause, typically between ages 45 and 55, oestrogen levels decline significantly. Blood pressure tends to rise, the cholesterol profile often worsens, and the protective vascular effects of oestrogen diminish. This is why cardiovascular risk in women rises substantially after menopause, and why postmenopausal women are encouraged to engage proactively with cardiovascular risk factor assessment.
What about HRT?
The role of hormone replacement therapy in cardiovascular risk has evolved considerably. Current evidence suggests that HRT initiated in the perimenopause period, within 10 years of menopause and before age 60, does not increase cardiovascular risk and may be beneficial in some women. HRT initiated later, in women with established cardiovascular disease or significant risk factors, requires more careful individual consideration.
This is an evolving field and a conversation worth having with a doctor who can review your full circumstances.
Risk Factors, Shared and Specific to Women
The traditional cardiovascular risk factors apply equally to women, but several carry a disproportionately greater impact in women than in men.
Diabetes
Approximately triples cardiovascular risk in women, compared to a doubling in men. A significantly greater relative impact.
Smoking
Confers greater cardiovascular risk in women than in equivalent male smokers. One of the most important modifiable factors.
Depression and stress
More common in women and more strongly associated with cardiovascular outcomes in women than in men.
Preeclampsia
Associated with a substantially higher lifetime risk of hypertension, stroke, and coronary artery disease, even after blood pressure normalises post-delivery.
Gestational diabetes
Resolves after delivery in most cases but carries significant risk of progressing to type 2 diabetes, itself a major cardiovascular risk factor.
Autoimmune conditions
Rheumatoid arthritis, lupus, and other autoimmune conditions, more common in women, carry elevated cardiovascular risk through chronic inflammation.
Pregnancy and Long-Term Cardiovascular Risk
Pregnancy acts as a cardiovascular stress test, the demands it places on the circulatory system can reveal vulnerabilities that may not otherwise become apparent until later in life.
A history of preeclampsia, gestational diabetes, or peripartum cardiomyopathy should always be shared with your cardiologist as part of your medical history. These are not simply obstetric details, they are cardiovascular risk information that actively shapes how your long-term heart health should be managed.
Peripartum cardiomyopathy
Peripartum cardiomyopathy is a rare but serious condition in which the heart muscle weakens in the last month of pregnancy or in the months following delivery. It can cause heart failure and requires prompt medical assessment. Most women recover fully with appropriate treatment, but follow-up and monitoring are important.
Conditions Predominantly Affecting Women
SCAD, spontaneous coronary artery dissection
SCAD is one of the most important and under-recognised cardiovascular conditions in women. It involves a sudden tear within the wall of a coronary artery, not at a site of atherosclerotic plaque, but in an otherwise healthy artery, which compromises blood flow and causes a heart attack.
SCAD most commonly affects women in their 40s and 50s and is particularly associated with the peripartum period, extreme physical or emotional stress, and underlying connective tissue conditions. It can occur in the complete absence of conventional cardiovascular risk factors, which is precisely why it may not be considered. Treatment differs importantly from standard heart attack management, and recognition is critical.
Takotsubo cardiomyopathy
Takotsubo, broken heart syndrome, affects women disproportionately, particularly postmenopausal women. The role of oestrogen withdrawal in increasing susceptibility to this stress-induced cardiac event is one of the most striking illustrations of the cardiovascular significance of hormonal changes in women.
Both SCAD and takotsubo are covered in full in dedicated Heart Matters articles.
- Given my age and menopausal status, what is my current cardiovascular risk, and has it been formally assessed?
- I had preeclampsia / gestational diabetes / peripartum cardiomyopathy during pregnancy, how does this affect my long-term cardiovascular risk?
- My symptoms don’t match the classic heart attack description, could they still be cardiac?
- Should I be on HRT, and what are the cardiovascular implications for me specifically?
- Are there any investigations, such as a coronary calcium score or microvascular assessment, that would be appropriate for my risk profile?

When in Doubt, Get Checked Out
If you experience chest discomfort, breathlessness, unusual fatigue, or any symptom that gives you pause, do not dismiss it or wait to see if it passes. Women’s heart symptoms are often less typical, and that is all the more reason to have them assessed rather than explained away.
Conclusion
Heart disease in women is not a minor variation on heart disease in men. It is, in important respects, a different clinical entity, with different presentations, different risk trajectories, different underlying mechanisms, and conditions that occur predominantly or exclusively in women.
The most important thing any woman can do is know her risk factors, share her complete obstetric history with her cardiologist, take symptoms seriously rather than dismissing them, and not accept a “normal for your age” explanation for symptoms that warrant proper investigation.
Advocacy for your own heart health is not hypochondria, it is sound clinical behaviour. You deserve the same quality of investigation and care as anyone else.
