What is heart disease?
Heart disease affects both sexes but often goes undetected in women. Although more men than women are admitted to hospital for heart attack, the number of deaths from heart attack in men and in women is roughly the same.
Cardiovascular disease (CVD) — often called ‘heart disease’ — is an umbrella term that includes diseases and conditions that affect the heart and blood vessels.
These include coronary heart disease (CHD) (also called ‘coronary artery disease’ and ‘ischaemic heart disease’), heart failure, arrhythmias, angina and others.
CHD is a common cause of heart attack, which occurs when blood supply to the heart is suddenly interrupted. The heart needs a constant supply of oxygen-rich blood delivered by the coronary arteries. If this is stopped, the heart muscle can get damaged and begin to die.
Why heart disease goes undiagnosed in women
Australian women are more likely to die from heart disease than breast cancer. This is partly because heart disease is often not recognised in women. The reasons for this include:
- Women often develop symptoms of heart disease at a much later stage in the illness than men.
- Symptoms can be more vague or non-specific in women.
- Women are less likely to seek help quickly.
- Some diagnostic tests for heart disease are less accurate in women than in men.
- Some health professionals may be less likely to check for heart disease in women.
There is also less community awareness of the risk of heart disease in females. Many Australian women (and men) mistakenly assume that heart disease mostly affects middle-aged men, which is not the case.
How men and women experience heart attack
Women and men can experience the signs and symptoms of a heart attack differently.
Men may experience:
- chest pain or discomfort
- shortness of breath
- nausea
Women may experience:
- back, neck or jaw pain or tightness
- a burning sensation in the chest (similar to heartburn)
- chest discomfort
- dizziness
- vomiting
- fatigue
- lightheadedness
- nausea
- shortness of breath
- sweating
Although chest pain is thought to be the most common symptom of heart attack — and it is common in men — only about half of all women who have a heart attack actually report chest pain.
Preventing heart disease in women and men
Women often focus on looking after partners, children or ageing parents, but it’s important for women also to prioritise their own health.
In Australia, 9 in every 10 women have one risk factor for heart disease, and half of all women have 2 or 3 risk factors. The risk factors for heart disease in both in women and men include high blood pressure, smoking, high cholesterol and diabetes.
Women can also have the added risk factors of pre-eclampsia or gestational diabetes (during pregnancy), which may increase the chances of developing heart disease later in life.
Whether you’re a woman or a man, you will reduce your risk of developing heart disease if you:
- know the risk factors for heart disease
- talk to your doctor about ‘cardiovascular screening’ based on your family history and risk factors
- quit smoking
- exercise regularly
- find ways to reduce stress
- stick to a healthy diet low in saturated fat and sugar and high in fibre
