What Does a Heart Attack Feel Like for Women?

While chest pain or pressure is still the most common symptom of a heart attack, women are more likely than men to also experience pain in the back, jaw, or neck, sudden extreme fatigue, nausea, or breathlessness – sometimes without obvious chest pain at all.

These symptoms can build gradually or come on suddenly, and because they can resemble less serious conditions, they're often mistaken for something else.

What are the signs and symptoms of a heart attack in women?

Chest pain or discomfort is still the most common heart attack symptom in women, reported by over 80% of women having a heart attack – but women are more likely than men to also have one or more of the following (Mehta et al., 2016; Mayo Clinic, 2024):

• Chest pain or discomfort – often described as pressure, fullness, or tightness rather than sharp pain, and it doesn't have to be on the left side.
• Pain in the arm(s), back, neck, shoulder, or jaw – can appear gradually or suddenly and intensely, and doesn't need to accompany chest pain to matter.
• Upper stomach pain or pressure – often mistaken for indigestion, heartburn, or a stomach ulcer.
• Shortness of breath – with or without chest discomfort, including breathlessness that isn't linked to exertion.
• Nausea, vomiting, or lightheadedness – easy to write off as a stomach bug or fatigue.
• Unusual, extreme fatigue – a level of tiredness that makes ordinary activities, like climbing a flight of stairs, suddenly feel difficult.
• Cold sweats – distinct from perspiration caused by heat or exercise.

Any of these on their own, or several together, are reason enough to seek emergency care immediately – women don't need to have classic chest pain for it to be a heart attack.

How is a heart attack in women different from a heart attack in men?

The biggest difference isn't that women don't get chest pain (most do), but that women are more likely to also have symptoms that don't obviously point to the heart, which makes it easier to dismiss or misattribute what's happening (Mehta et al., 2016).

This shows up in local data too. A Singapore Myocardial Infarction Registry analysis of heart attack patients aged 20 to 64 found that younger women were more likely than men to have atypical symptoms, a prior history of ischaemic heart disease, and a worse 28-day survival rate – differences that disappeared in patients over 64 (Kam et al., 2002).

Why younger women in particular present differently isn't fully understood.

Dr Deanna Khoo, cardiologist at Gleneagles Hospital, shares: "Younger women who develop a heart attack may have a broader range of underlying mechanisms, including coronary artery spasm, microvascular dysfunction, and spontaneous coronary artery dissection, in addition to conventional atherosclerotic coronary disease. There may also be sex-related differences in autonomic responses, pain perception, and the way ischaemic symptoms are experienced and described."

Singapore Heart Foundation data also shows that while heart attacks occur more often in men, the fatality rate is higher in women, largely because women tend to be older when a heart attack occurs (Singapore Heart Foundation, n.d.).

What causes a heart attack in women?

Most heart attacks in women, as in men, are caused by coronary artery disease – a buildup of fatty plaque that narrows or blocks the arteries supplying the heart. Several less common causes disproportionately affect women, and are worth knowing:

• Spontaneous coronary artery dissection (SCAD): A tear in the artery wall, unrelated to plaque buildup, that most often affects younger and middle-aged women with few or no traditional risk factors. It's linked to pregnancy and the postpartum period, hormonal factors, and connective tissue conditions, and accounts for a meaningful share of heart attacks in women under 50 (Adlam et al., 2018).
• Takotsubo cardiomyopathy ("broken heart syndrome"): A sudden weakening of the heart muscle triggered by intense emotional or physical stress. It can look identical to a heart attack on first assessment, but there's no blocked artery, and about 90% of cases occur in postmenopausal women (Ghadri et al., 2018).
• Pregnancy-related and hormonal factors: Conditions like preeclampsia, high blood pressure in pregnancy, and gestational diabetes are linked to higher cardiovascular risk later in life, and menopause itself is associated with a rise in heart disease risk (American Heart Association, 2024).
• Coronary microvascular dysfunction and microvascular spasm: Women are more likely to have problems affecting the heart’s tiny blood vessels. These vessels may not widen properly or may suddenly tighten (spasm), temporarily reducing blood flow to the heart. This can cause chest pain and, occasionally, a heart attack, even when the major coronary arteries appear normal.

None of this replaces the standard, well-known risk factors: high blood pressure, high cholesterol, diabetes, smoking, and family history all matter for women just as much as for men.

What is a silent heart attack in women?

A silent heart attack (silent myocardial infarction) is one that happens with minimal, unusual, or no noticeable symptoms, and is often only discovered later – sometimes on a routine ECG – rather than at the time it occurs.

Research on this can look contradictory at first glance. An early, long-running analysis of the Framingham Heart Study found unrecognised heart attacks were more common in women than men (35% vs. 28%) (Kannel, 1986), while more recent population studies using imaging to detect old, undiagnosed heart attacks have sometimes found a higher raw prevalence in men.

Dr Deanna Khoo, cardiologist at Gleneagles Hospital, explains why: "The data is not consistent that silent MIs are more common in women compared to men. Women have a higher likelihood of an MI not being immediately recognised, sometimes because of atypical symptoms. But absolute rates of silent MIs may be overall higher in men due to the higher prevalence of the disease in men overall."

In other words, women aren't necessarily having more silent heart attacks – but when a woman does have one, it's more likely to go unrecognised at the time. What's not in question is how serious that is:

"A silent heart attack is not a harmless one," Dr Khoo adds. "Even when it goes unnoticed at the time, it can damage the heart and carries a similar long-term risk of heart failure, stroke, and death as a heart attack that is recognised when it occurs."

How long do heart attack symptoms last in women?

Continuous chest pain lasting 20 minutes or more, not relieved by rest, is a well-recognised red flag and one of the two most common symptoms reported by heart attack patients in Singapore (Singapore Heart Foundation, n.d.).

But for women specifically, symptoms don't always follow this pattern; they can be intermittent, come and go, or build up gradually over hours or even days rather than announcing themselves as one sudden, unmistakable event. This is part of why women's heart attacks are more easily explained away as something else.

The duration or pattern of a symptom shouldn't be used to decide whether it's "serious enough" to act on. If a symptom is new, unexplained, and doesn't have an obvious other cause, it's reason enough to seek emergency care.

How long can a heart attack last?

A heart attack is an evolving medical event, not a single moment; the longer the blood supply to part of the heart muscle stays blocked, the more permanent damage accumulates. This is the clinical basis for the phrase "time is muscle": treatment to restore blood flow within the first couple of hours has a significantly better chance of limiting lasting heart damage than treatment delayed by many hours.

This is precisely why waiting to see if symptoms "pass" is risky, regardless of how mild or intermittent they seem – the underlying event can still be progressing even while the symptoms feel manageable.

How to prevent a heart attack in women?

Prevention for women rests on the same core pillars as for men, with a few additional points worth flagging specifically:

• Manage the core risk factors – blood pressure, cholesterol, and blood sugar, through regular screening rather than waiting for symptoms.
• Don't smoke – and seek support to quit if you do; smoking remains one of the most modifiable major risk factors.
• Stay active and maintain a healthy weight – regular movement supports nearly every cardiovascular risk factor at once.
• Flag pregnancy complications to your doctor as a long-term marker, not just a pregnancy-specific issue – a history of preeclampsia or gestational diabetes is worth mentioning at check-ups well beyond the pregnancy itself.
• Ask specifically about menopause and heart risk – this is a life stage where cardiovascular risk changes, and it's worth raising proactively rather than assuming it will come up.

It's also worth knowing that awareness among healthcare providers has historically lagged here too – one American Heart Association survey found only 22% of primary care physicians and 42% of cardiologists felt well prepared to address cardiovascular risk specifically in women (American Heart Association, 2024). Asking direct questions about your own heart health risk, rather than assuming it will be raised for you, is a reasonable and useful thing to do.

What should I do if I think I'm having a heart attack?

• Call 995 immediately. Don't drive yourself or wait to see if symptoms pass; call for an ambulance right away.
• Stay as calm and still as possible while waiting for help to arrive.
• Unlock your door if you're home alone, so paramedics can reach you.
• Don't take any medication you haven't already been specifically advised to take for a cardiac event; check with your doctor in advance about whether this applies to you, rather than deciding in the moment.

If you have concerns about your heart health – including family history, pregnancy-related complications, or symptoms that don't feel quite right – speak with a cardiologist. Trusting your own sense that something is wrong is, on its own, a good enough reason to get checked.
