Cardiovascular Risk Check
A two-minute screening to estimate your 10-year risk of a heart attack or stroke, using the WHO/ISH risk chart for the Africa region.
Estimated 10-year risk of a fatal or non-fatal cardiovascular event
Cardiovascular Risk
⚠️ Antihypertensive Medication Note
Methodology & Limitations.
This tool uses the 2007 WHO/ISH cardiovascular risk prediction chart for
WHO epidemiological sub-region AFR-D (covering Nigeria and neighbouring
West/Central African countries), estimating 10-year risk of a fatal or non-fatal
cardiovascular event from age, sex, smoking status, diabetes history, systolic blood
pressure, and — when provided — total cholesterol.
Important limitations: (1) The 2007 charts are the validated methodology this tool is built on. WHO updated its CVD risk charts in 2019 (Lancet Global Health 2019;7:e1332–45), extending coverage to 21 regions and recalibrating with GBD data; Nigeria now falls under “Western Sub-Saharan Africa” in that framework. This tool will be updated to the 2019 methodology in due course. (2) The chart is validated for adults aged 40–74; results outside this range are extrapolated estimates. (3) HDL, TC:HDL ratio, blood glucose, BMI, and antihypertensive status are shown as supplementary advisories only. The WHO/ISH risk band is derived solely from age, sex, smoking, diabetes, systolic BP, and total cholesterol (per the 2007 methodology). (4) This is a screening aid, not a diagnosis. All results must be interpreted by a qualified clinician alongside the patient’s full medical history.
