About ASCVD Risk Calculator

Places a 10-year atherosclerotic cardiovascular disease risk percentage into the ACC/AHA risk tiers and shows the LDL reduction associated with each tier.

Formula

ACC/AHA 2018 tiers

Low <5%; Borderline 5-7.4%; Intermediate 7.5-19.9%; High >=20%. Expected LDL reduction: >=50% high-intensity, 30-49% moderate-intensity statin

Worked example

With the default values below, ASCVD Risk Calculator returns ACC/AHA risk category of Intermediate risk (7.5-19.9%). Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.

Frequently Asked Questions

Where does the risk percentage come from?

From the ACC/AHA Pooled Cohort Equations, which need the full sex- and race-specific coefficient set; enter the percentage they produce here.

Why show events per 100 people?

Absolute risk is easier to interpret than a percentage when discussing whether treatment is worthwhile.
