Know Your Heart Attack Risk

Estimate your chance of having a heart attack or stroke in the next 10 years. Answer the questions below. This tool uses the QRISK3-2017 formula and runs in your browser; nothing you enter is stored or sent anywhere.

Who can use it: adults aged 25 to 84 who have not already had a heart attack or stroke and have no known heart disease or angina.

Enter total and HDL cholesterol in the same unit (both mg/dL or both mmol/L). Only their ratio is used.

Tick everything that applies to you
Optional: extra blood tests (risk enhancers, especially relevant for Indians)

Indians often carry a higher risk than standard calculators show. These tests do not change the QRISK3 percentage above, but a high value suggests your true risk may be higher. Leave blank if you do not have the result.

Disclaimer: This calculator gives an estimate only. It uses the QRISK3-2017 formula, which was developed from UK patient records and has not been specially validated for people in India, so it may over- or under-estimate your risk. It is for general information, is not a diagnosis, and does not replace a medical assessment. If you have chest pain, breathlessness or other sudden symptoms, go to the nearest emergency department immediately.

Consult your doctor to understand your result and decide what to do next.

Algorithm credit and required notice

Based on the open-source QRISK3-2017 algorithm (Hippisley-Cox J, Coupland C, Brindle P. BMJ 2017;357:j2099), Copyright 2017 ClinRisk Ltd., released under the GNU Lesser General Public License. This is not the official QRISK calculator; the official tool is at qrisk.org. QRISK is a registered trademark of its owners. Assumptions made here: no Townsend deprivation score and no blood pressure variability are used (population averages are applied); BMI is limited to 20 to 40.

The initial version of the algorithm source, found at http://svn.clinrisk.co.uk/opensource/qrisk2, faithfully implements QRISK3-2017. ClinRisk Ltd. have released this code under the GNU Lesser General Public License to enable others to implement the algorithm faithfully. However, the nature of the GNU Lesser General Public License is such that we cannot prevent, for example, someone accidentally altering the coefficients, getting the inputs wrong, or just poor programming. ClinRisk Ltd. stress, therefore, that it is the responsibility of the end user to check that the source that they receive produces the same results as the original code found at https://qrisk.org. Inaccurate implementations of risk scores can lead to wrong patients being given the wrong treatment.
