QRISK3 — 10-Year Cardiovascular Risk

Approximates the QRISK3 (UK-validated) 10-year risk of myocardial infarction or stroke. NICE NG238 recommends QRISK3 for primary prevention statin decisions in adults 25–84 years. This calculator uses additive risk weights for clinical use; for the formal logistic model use the official QRISK3 web tool. Not validated in established CVD, T1DM, eGFR <30, or familial hypercholesterolaemia.

Used in: Hypertension

How to use & interpret

QRISK3 estimates the 10-year risk of cardiovascular disease (heart attack or stroke) for primary prevention in adults aged 25–84 without established CVD. It includes a wide range of factors — age, sex, ethnicity, deprivation, blood pressure (and its variability), cholesterol ratio, BMI, smoking, diabetes, and several conditions such as chronic kidney disease, atrial fibrillation, rheumatoid arthritis, migraine, SLE and severe mental illness.

In UK practice (NICE), a 10-year risk of ≥10% prompts a discussion about starting a statin alongside lifestyle measures. It is not for people who already have CVD, type 1 diabetes, or familial hypercholesterolaemia, who are managed under separate guidance.

Score interpretation

Low 10-year CVD risk (<10%) 0–10

→ Lifestyle advice (Mediterranean diet, exercise, smoking cessation, weight optimisation). Reassess every 5 years if untreated.

Moderate 10-year CVD risk (10–20%) 11–20

→ Atorvastatin 20 mg OD per NICE NG238 if no contraindications; intensify lifestyle change; recheck lipids and LFTs at 3 months. Consider ACR / lipid review.

High 10-year CVD risk (≥20%) 21–100

→ Atorvastatin 20 mg OD (titrate to ≥40% non-HDL reduction); BP target <140/90 (or <130/80 if T2DM/CKD); aspirin only if established CVD; consider FH testing if early CHD or LDL>4.9.

Frequently asked questions

What QRISK3 score means a statin should be offered?

NICE suggests discussing a statin (with lifestyle advice) when the 10-year CVD risk is 10% or higher, as part of shared decision-making rather than an automatic prescription.
