Heart risk assessment

Also called cardiovascular risk assessment, or a heart check

Key points about heart risk assessment

A heart risk assessment is an estimate of how likely you are to have a heart attack or stroke in the next 5 years.
The age you should start having heart checks depends on your sex, ethnicity and other risk factors.
You can use an online tool called My Heart Check to give you an idea of your heart health.
You can also do a heart risk assessment with your GP or nurse. This is the best option if you have had a heart attack, stroke or other heart condition.
You can improve your heart health by stopping smoking, exercising regularly, healthy eating and drinking, managing stress and taking medicines if you need to.

A heart risk assessment is an estimate of how likely you are to have a heart attack or stroke in the next 5 years. You will get a percentage score such as 10%. This means that out of 100 people with the same risk factors as you, 10 of them will have a heart attack or stroke in the next 5 years.

The score is calculated by building a risk profile based on a series of factors including:

age
gender
ethnicity
cholesterol levels
smoking history
blood pressure
family history of an early heart attack or stroke and other conditions
medical history – past or current heart problems, atrial fibrillation (AF), diabetes, kidney disease or stroke.

Some of these factors you can't change, but there are many that you can. That means the choices you make every day do matter. Over time, what you eat, drink, do and how you live increases or decreases your risk of heart disease and stroke.

The age when you are advised to start having heart checks depends on your sex, ethnicity and other risk factors.

My Heart Check tool

While the best option is to have a heart risk assessment with your healthcare provider, you can use an online tool called My Heart Check to give you an idea of your heart health. My Heart Check(external link) is a free online heart health check developed by the Heart Foundation. It's designed for Kiwis as it's based on New Zealand data.

It can estimate your heart age compared to your actual age, as well as giving you an estimate of your risk of having a heart attack or stroke in the next 5 years.

This free online tool works best for people aged 30–75. You can still use it if you are older or younger, but your result may be less accurate.

Use My Heart Check(external link) to:

get an idea of your heart health
get tips for how to improve your heart health
talk about your heart health with a healthcare professional.

You will need to provide information such as:

your age
your height and weight
your cholesterol levels (lipid profile)
your blood pressure
your medical history.

If you're not sure about some of this information, you can leave it out, as the tool can base your results on an estimate.

Note that this tool is not recommended if you have had a heart attack or stroke or have another heart condition.

GP or nurse

The best (most accurate) option is to have a heart risk assessment with your healthcare provider. They can calculate your heart risk based on your age, medical history and all the other risk factors. They can also advise how often you need a heart risk assessment based on your situation.

Seeing your GP or nurse is also the best way to find out your heart health if you have had a heart attack, stroke or other heart conditions, as they know how to manage your condition.

See your healthcare provider. Based on your risk score, they will advise what you need to do, such as make lifestyle changes or start taking medicines for blood pressure, cholesterol or diabetes. Your healthcare provider will also let you know how often you would need to have a heart risk assessment based on your risk score to maintain your heart health.

Knowing your risk can help motivate you to make some positive lifestyle changes. You have an important role to play in your heart health. While some risk factors can't be changed, others can. The choices you make every day do matter. Over time, what you eat, drink, do and how you live can improve your blood pressure and your cholesterol level. It can also improve the health of your arteries (atherosclerosis) and decrease your risk of heart disease and stroke.

Even a small change can have a positive impact on your risk of heart attack and stroke. The more healthy changes you make, the better it is for your heart health.
