HEART Score Calculator

HEART Score Calculator for Cardiology. Totals 0-3, 4-6 and 7-10 are low, intermediate and high HEART score categories. They are not automatic discharge/admission orders or fixed personal event probabilities.

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

How this calculator works

Each of history, ECG, age, risk-factor burden and troponin contributes 0-2. Age is below 45, 45 to below 65, or at least 65. This implementation makes troponin boundaries explicit: at most one times the assay upper reference limit scores 0, above one but below three scores 1, and at least three scores 2.

When to use this calculator

Clinician assessment of acute chest pain with an appropriate ECG and assay-specific troponin pathway.

Inputs used

  • Clinical suspicion from history
  • ECG findings
  • Age (years)
  • Risk-factor burden
  • Troponin / assay upper reference limit (ratio)

Clinical interpretation

Totals 0-3, 4-6 and 7-10 are low, intermediate and high HEART score categories. They are not automatic discharge/admission orders or fixed personal event probabilities.

Worked example

History 1, ECG 1, age 55 contributing 1, risk-factor burden 2 and troponin exactly at the upper reference limit contributing 0 total 5. Troponin ratio 3 contributes 2.

Limitations and safety notes

History and ECG interpretation remain clinician-dependent. Different source shorthand and assay pathways can use different troponin conventions; the local convention is explicit. The score is not the serial-troponin HEART Pathway and cannot exclude ACS alone.

Frequently asked questions

Why use a troponin ratio instead of a concentration?

The upper reference limit depends on the assay. A ratio makes the selected boundary visible, but does not remove the need for serial sampling or the applicable clinical protocol.

What does this result leave unresolved?

History and ECG interpretation remain clinician-dependent. Different source shorthand and assay pathways can use different troponin conventions; the local convention is explicit. The score is not the serial-troponin HEART Pathway and cannot exclude ACS alone.

  • 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.
