Heart attack and stroke – calculating your risk score
About heart attack and stroke
Coronary heart
disease
External Link
, along with
stroke
and blood vessel disease, belongs to the group of conditions known as cardiovascular disease.
Coronary heart disease is the main cause of heart attacks. Every day, 45 Australians die from coronary heart disease.
Some people may not be aware they are at risk of a
heart
attack
External Link
or stroke because risk factors can be silent. For example, you may have
high
cholesterol
External Link
or
high blood
pressure
External Link
without having any symptoms.
High cholesterol and high blood pressure are risk factors for heart attack and stroke, along with other modifiable risk factors like physical inactivity and poor diet.
As part of a
Heart Health
Check
External Link
, your doctor will calculate your risk of having a heart attack or stroke in the next 5 years. This is called your cardiovascular disease risk score. By knowing your risk score, your doctor can support you to take steps to reduce your risk of a heart attack or stroke.
What is a Heart Health Check?
A Heart Health Check is a 20-minute check up with your doctor which is subsidised by Medicare. You are eligible for a Heart Health Check if you:
have not had a heart attack or stroke, and
you are over 45 years of age (or over 30 years for Aboriginal and Torres Strait Islander people).
As part of a Heart Health check, your doctor will:
ask you about your medical and family history of heart disease
ask you about your lifestyle, including your diet, physical activity, and if you smoke or drink alcohol
check your blood pressure, cholesterol and blood sugar levels.
Your doctor will then take this information and use it to calculate your cardiovascular disease risk score.
Knowing your risk score will help you and your doctor to make immediate decisions about the best action to take to improve your heart health. This can include lifestyle changes like following a
heart-healthy eating
pattern
External Link
and
moving
more
External Link
. Some people may also need to take
medicines
External Link
to manage their blood pressure and cholesterol levels.
If you identify as Aboriginal or Torres Strait Islander, it’s recommended you see your doctor or Aboriginal Health Practitioner from age 18 to identify any heart disease risk factors as early as possible.
Factors used to calculate your risk score for heart attack and stroke
Your doctor will calculate your cardiovascular disease risk score based on your modifiable and non-modifiable risk factors.
Modifiable risk factors are factors that you can change. Non-modifiable risk factors are factors you can’t change.
Heart attack and stroke risk factors that you can change include:
tobacco
smoking
External Link
poor
diet
External Link
physical
inactivity
External Link
overweight or
obesity
External Link
alcohol intake
.
There are also some health conditions that increase risk:
high cholesterol
high blood pressure (hypertension)
type 2 diabetes
depression, anxiety and social
isolation
External Link
.
Risk factors you can’t change include:
your age
whether you were born male or female (your sex)
being post-menopausal
having a premature family history of heart disease (where one or more of your immediate family members, such as a parent or sibling, has had a heart attack or stroke before the age of 65).
Aboriginal and Torres Strait Islander people, and people from South Asian, Middle Eastern, Māori and Pacific Islander backgrounds are also at increased risk.
Calculating your risk score for heart attack and stroke
After considering your risk factors, your doctor will calculate your risk score, which is a percentage.
The percentage gives the probability of you having heart attack or stroke in the next 5 years. In other words, whether you are at low, intermediate or high risk.
Some people who have certain medical conditions do not need a risk score, because they are already at high risk. Your doctor will tell you if you are in this group and advise you about what to do to reduce your risk.
Making changes based on your risk score for heart attack and stroke
Depending on your risk score, your doctor will recommend changes to your health or lifestyle. In some cases, you may also need to take
medicines
External Link
to help reduce your risk.
No matter what your risk score, there are changes that you can make to improve your heart health:

smoking
