medical calculators · cardiovascular risk

Know the number before it knows you.

Four complementary tools to estimate and refine your cardiovascular risk — the current AHA PREVENT equations, the legacy ASCVD calculator, and the coronary calcium tools that add measured plaque to the picture. Every result can be saved as a Funktion PDF report and brought to your consultation.

How a 10-year risk reads as people, not a percentage — and how it moves when the modifiable numbers change.
01

AHA PREVENT risk

preferred · acc/aha dyslipidaemia guideline

The current standard for primary-prevention risk. Estimates your 10-year — and, under 60, your 30-year — risk of total cardiovascular disease, using kidney function alongside the classic factors. Ages 30–79.

Khan SS et al., Circulation 2023 — AHA PREVENT™ base equations, validated in 6.6 million adults.

02

ASCVD risk (2013)

legacy · pooled cohort equations

The previous-generation 10-year calculator, kept for continuity with older estimates and clinical letters. Ages 40–79. For a current estimate, prefer PREVENT above.

03

Coronary calcium risk

mesa · risk refined by a cac scan

If you have had a coronary artery calcium (CAC) scan, this folds the measured score into your 10-year coronary heart disease risk — and shows the estimate with and without the scan, so you can see how much the measurement changes the picture. Ages 45–85.

Calcium percentile

mesa reference · your score against your peers

The same calcium score means different things at different ages. This places your score against people of your age, sex and ethnicity — showing whether your calcium burden is typical, or ahead of schedule. Ages 45–84.

Four tools, one sequence.

  • start with preventIt is the preferred first estimate. If your risk lands clearly low or clearly high, the decision is usually straightforward.
  • refine with calciumNear a treatment threshold, a CAC scan settles the question: the MESA calculator re-estimates risk with the measured score, and the percentile shows whether that score is early for your age.
  • bring it to usSave any result as a PDF and bring it to a consultation — we read it with your labs, history and goals, then write the plan.
  • the fine printThese calculators are educational tools implemented from the cited publications. They do not store or send your data — everything is computed in your browser — and they are not a substitute for medical advice.
