The School of Medicine at Cardiff University is funding a randomised controlled trial into the graphical presentation of cardiovascular risk.

The aim of this study is to compare the effects of presenting cardiovascular risk in different ways on an individual’s intention to change behaviour to reduce risk and their understanding of risk information.


Heart disease is the biggest killer in the UK and many people are unaware of the risk. Heart disease risk can be reduced by making changes to lifestyle, such as adopting healthier behaviours. The future risk of heart disease can be predicted but more research is needed into how this risk should be presented.

About the study

800 individuals’ aged between 45 and 64 years, who have not been previously diagnosed with heart disease and have access to a computer with the internet, will be given a link to a website comprising a risk calculator.  This will predict an individual’s future 10-year risk of having a coronary heart disease event, by using information about their health and lifestyle. The risk calculator randomises participants to view different graphical risk presentations and asks them to complete a questionnaire.
