Formula and variables

Displayed formula: Chest pain risk stratification

The engine evaluates: HEART score (points). Variable names match the input field keys so you can trace each step from entry to output.

How to use this tool

1. Open the HEART Score and enter your values using the units shown beside each field.
2. Review that inputs are within the typical physiological range before you calculate.
3. Read the result together with the interpretation notes below and your local clinical context.

How to interpret the result

Scores 0–3 support early discharge pathways in validated settings; 4–6 warrant observation; 7–10 indicate high risk and aggressive evaluation. Always follow institutional chest pain protocols.

Clinical context

Cardiovascular calculations support assessment but never replace ECG, imaging, troponin trends, or emergent reperfusion pathways when STEMI is suspected.
