ASCVD Risk Calculator

ASCVD Risk Calculator for Cardiology. The probability concerns the historical hard ASCVD endpoint, not all cardiovascular disease, lifetime risk or a current treatment recommendation. The title explicitly identifies the old model.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

The restored historical model uses the four published 2013 Pooled Cohort Equation coefficient sets, including logarithms, interactions, baseline survival and centering terms. Ten-year hard-ASCVD probability is 100 x [1 - S0 raised to exp(linear predictor - mean)]. It no longer uses arbitrary risk-factor multipliers.

When to use this calculator

Historical model learning and comparison for adults aged 40-79 without established ASCVD. Current 2026 US lipid guidance uses PREVENT-ASCVD, not this implementation.

Inputs used

  • Age (years)
  • Sex coefficient in the source model
  • Historical derivation cohort (not a biological race adjustment recommendation)
  • Total cholesterol (mmol/L; US mg/dL)
  • HDL cholesterol (mmol/L; US mg/dL)
  • Systolic pressure (mmHg)
  • Diabetes
  • Current smoking
  • Current antihypertensive treatment

Clinical interpretation

The probability concerns the historical hard ASCVD endpoint, not all cardiovascular disease, lifetime risk or a current treatment recommendation. The title explicitly identifies the old model.

Worked example

At age 55, total cholesterol 213 mg/dL, HDL 50, untreated systolic BP 120, no diabetes and no smoking, the White-male coefficient equation yields approximately 5.38%. The source's worked example reports approximately 5.3% using its rounded intermediate values; other published cohort examples are checked in the regression suite.

Limitations and safety notes

Historical sex/race cohort categories have transportability and equity limitations; no other cohort is silently treated as White. PREVENT licensing/code access has not been completed. This is not PREVENT or the official ASCVD Risk Estimator Plus app.

Frequently asked questions

Does this implement PREVENT or current statin thresholds?

No. It is the historical Pooled Cohort model. The contemporary model requires its own specification, access terms and appropriate patient scope.

What does this result leave unresolved?

Historical sex/race cohort categories have transportability and equity limitations; no other cohort is silently treated as White. PREVENT licensing/code access has not been completed. This is not PREVENT or the official ASCVD Risk Estimator Plus app.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
