How can I work out if I am at risk of heart disease?

A heart risk assessment will help you find out your risk of heart disease by building a picture of your risk based on factors such as your age, sex, ethnicity, cholesterol levels, smoking history, blood pressure, family history and other health conditions.

Different people need a heart risk assessment at different ages. Find out more about heart risk assessment.

How is heart disease diagnosed?

There are several different tests and investigations used to check on your heart health and to diagnose and monitor any heart condition you may have. These include an ECG (electrocardiogram), echocardiogram and coronary angiography.

The tests your doctor chooses for you will depend on your risk of heart disease, your history of heart problems and the symptoms you might have.

How is heart disease treated?

There are a number of treatments for heart disease, depending on the condition. This may include medicines, procedures such as coronary artery bypass surgery, angioplasty (stent) and valve surgery

What happens when I am discharged from hospital?

If you need surgery for your heart condition, there are a few things you need to do or keep track of after you are discharged from the hospital. 

  • Cardiac rehabilitation – Cardiac rehabilitation is the term used to describe the education, training and support for people who have had a heart attack or developed heart disease. Ask your doctor about what is available in your area. Read more about cardiac rehabilitation
  • Taking your medicines – you will need to take your medicines regularly if prescribed by your doctor. This is to make sure that you recover well from your heart disease or heart surgery. Some of these may need to be taken for life. 
  • Healthy lifestyle – It is important that you maintain a healthy lifestyle even after your heart disease has been treated or you have recovered. This includes healthy eating and drinking, stopping smoking, maintaining a healthy weight, exercising according to your ability and good control of your diabetes or cholesterol level. 
  • Attending follow-up appointments – Your doctor may set up appointments for you a few weeks to months after you have been discharged. It is important to attend these appointments as this gives your doctor a good idea of how well you are recovering and whether any further treatment is needed. 

For more information about the recovery process, see the Heart Foundation’s booklet Living well after a heart attack.
