lipid modification: primary + secondary prevention (statins)

qrisk3 thresholds, atorvastatin 20 mg primary prevention, atorvastatin 80 mg secondary prevention, and lipid targets.

At-a-glance

• Use QRISK3 for most adults 25–84 without established CVD. • Primary prevention: offer atorvastatin 20 mg when QRISK3 ≥10% (after shared decision-making). • Secondary prevention: offer atorvastatin 80 mg for established CVD unless lower dose is indicated. • Targets: primary prevention aims >40% reduction in non-HDL; secondary prevention targets LDL ≤2.0 mmol/L or non-HDL ≤2.6 mmol/L.

Primary prevention (NICE NG238)

  • Risk estimation: use QRISK3 for people aged 25–84 without established CVD (and recognise where risk may be underestimated).
  • Offer statin: atorvastatin 20 mg for primary prevention when 10-year QRISK3 risk is ≥10%, after an informed discussion of benefits/harms and patient preferences.
  • Lipid target: aim for a >40% reduction in non-HDL cholesterol once on statin therapy.

Secondary prevention (established CVD) (NICE NG238)

  • Initial treatment: offer atorvastatin 80 mg to people with established CVD, whatever their baseline cholesterol, unless drug interactions, high adverse-effect risk, or patient preference indicates a lower dose.
  • Lipid targets: for secondary prevention, aim for LDL ≤2.0 mmol/L or non-HDL ≤2.6 mmol/L.
  • If not at target: optimise adherence, address secondary causes, up-titrate where tolerated; consider add-on therapies in line with NICE technology appraisals (e.g., ezetimibe) and local lipid pathways.

Before starting and monitoring (practical checklist)

  • Baseline: full lipid profile, assess secondary causes (e.g., hypothyroidism, nephrotic syndrome), medication review, lifestyle discussion.
  • Safety: counsel on muscle symptoms and interactions; consider baseline LFTs per local policy.
  • Follow-up: re-check lipids to confirm expected response and adjust intensity/adjuncts to meet targets.

Frequently asked questions

What statin dose is recommended for primary prevention at QRISK3 ≥10%?
NICE NG238 recommends offering atorvastatin 20 mg for primary prevention when 10-year QRISK3 risk is 10% or more (after shared decision-making).
What statin dose is recommended for established CVD?
NICE NG238 recommends atorvastatin 80 mg for secondary prevention unless lower dose is needed due to interactions, adverse-effect risk, or patient preference.
What lipid targets should I use?
Primary prevention: aim for >40% reduction in non-HDL cholesterol. Secondary prevention: aim for LDL ≤2.0 mmol/L or non-HDL ≤2.6 mmol/L.
