Cardiovascular Risk Calculator

Estimate 10-year risk of a fatal or non-fatal cardiovascular event using the WHO non-laboratory chart matched to the patient's country and global risk region.

Global region-specific calculation The country selection automatically applies one of the 21 WHO recalibrated global-region charts. This version uses age, sex, current smoking, systolic blood pressure and BMI, so no laboratory result is required. Nothing entered on this page is stored.

Clinical inputs

For adults aged 40-74 years who do not already have established cardiovascular disease.

Reference This implementation uses the published WHO 2019 non-laboratory-based cardiovascular risk charts for 21 global regions. WHO HEARTS risk-based CVD management and WHO non-laboratory charts .
Clinical safety note This is a chart-based primary-prevention estimate, not a diagnosis or treatment instruction. It is not applicable to established CVD, does not replace urgent assessment, and must be interpreted with current national guidance, comorbidities and clinical judgement.
