HEART Score Calculator for Chest Pain
Five items — History, ECG, Age, Risk factors, Troponin — stratify undifferentiated chest pain into MACE risk bands that actually change disposition. With the vascular neurology angle: the same substrate that infarcts myocardium embolizes brain.

HEART Score
Score each element for an ED patient with chest pain. Total 0–10; bands at 0–3, 4–6, and 7–10.
Score every item to see the MACE risk band and disposition implication.
Educational tool only. HEART informs disposition in undifferentiated chest pain; it does not apply once STEMI, a new ischemic ECG requiring immediate action, or hemodynamic instability is present, and it does not replace serial troponins, clinical judgment, or in-person evaluation.

Why HEART displaced TIMI and GRACE in the ED
TIMI and GRACE were derived in confirmed ACS populations; HEART was built for the actual ED question — the undifferentiated chest pain patient who probably does not have ACS. Its output maps cleanly onto disposition: 0–3 identifies a group with roughly 1–2% 6-week major adverse cardiac events, safe for accelerated discharge pathways when paired with negative serial troponins; 7–10 identifies a ~50% MACE group that needs admission and early invasive strategy. The "History" item is the score's soul and its weakness — it deliberately encodes clinician gestalt, which makes it perform like an experienced clinician and inherit that clinician's variability.
The vascular neurology connection
Two points of contact. First, established cerebrovascular disease scores +2 under Risk factors — a prior stroke or TIA moves a chest-pain patient's HEART score materially, and rightly so: post-stroke patients carry roughly double the long-term MACE risk, and cardiac events are a leading cause of death after ischemic stroke. Second, the traffic runs both ways — troponin elevation after acute stroke is common (neurogenic myocardial injury, especially with insular involvement, plus genuine type 2 and occasionally type 1 MI). A modestly positive troponin in a fresh stroke patient should be interpreted with the stroke in view, not fed mechanically into a chest-pain score; conversely, new AF discovered during an ACS workup is a stroke-prevention decision waiting to happen (CHA₂DS₂-VASc lives one tab over).
Frequently asked questions.
What counts as MACE in the HEART studies?
Acute myocardial infarction, percutaneous coronary intervention, coronary artery bypass grafting, or death within 6 weeks of presentation.
Can a HEART score of 0–3 be discharged without troponin?
No — the modern pathways (HEART Pathway) pair the low-risk score with negative serial troponins before discharge. Troponin is one of the five items, and the discharge evidence was generated with biomarker confirmation.
Does prior stroke really count as +2 under risk factors?
Yes — established atherosclerotic disease (coronary, cerebral, or peripheral) scores +2 regardless of the count of conventional risk factors. Atherosclerosis is one disease wearing three costumes.
When does HEART not apply?
STEMI or a new ischemic ECG demanding immediate action, hemodynamic instability, or an obvious alternative diagnosis (dissection, PE) — those patients exit the undifferentiated pathway the score was built for.
