Medical context

Risk-stratify ED chest pain for short-term major adverse cardiac events using HEART.

Emergency clinicians use this at triage, resuscitation, and disposition to standardize risk communication across shifts.

This page explains the HEART formula, how to interpret the output, known limitations, and peer-reviewed references so you can verify results against primary sources and local protocols.

It is grouped under Emergency Medicine because trauma, triage, and acute risk scores used in the ed.

Frequently asked questions

Can low HEART discharge everyone?
Only within validated institutional pathways that include follow-up and exclusion criteria.
Is the HEART result enough to make a treatment decision?
No. Calculators support medical decision-making but do not replace examination, shared decision-making, institutional protocols, or consultant input when stakes are high.
