Calculation Results

Total HEART Score: 3 Points Low Risk (MACE Risk: 1.7%)
6-Week Major Adverse Cardiac Event (MACE) Risk: 0.9% - 1.7%
Clinical Management Pathway: Candidate for Early Emergency Department Discharge
Recommended Disposition: Outpatient Cardiology Follow-Up Within 72 Hours

About This Calculator

Stratify 6-week risk of Major Adverse Cardiac Events (MACE: myocardial infarction, PCI/CABG, death) in emergency department chest pain patients using the HEART criteria.

Frequently Asked Questions

What does the HEART score assess?

The HEART score assesses 5 clinical components (History, ECG, Age, Risk factors, Troponin) in emergency department patients presenting with potential Acute Coronary Syndrome (ACS) to predict the 6-week risk of Major Adverse Cardiac Events (MACE).

What is considered a low-risk HEART score?

A score of 0 to 3 is considered Low Risk, with an estimated 6-week MACE rate under 1.7%. These patients can be safely discharged from the emergency department with outpatient follow-up.

What constitutes a moderate-risk and high-risk score?

A score of 4 to 6 represents Moderate Risk (~12-16% MACE) requiring admission for serial cardiac enzymes and provocative stress testing or CTA. A score of 7 to 10 represents High Risk (>50% MACE) warranting early invasive coronary angiography.

Does the HEART score apply if the patient has a STEMI?

No. Patients with acute ST-segment elevation myocardial infarction (STEMI) require immediate activation of the cardiac catheterization lab for primary PCI; the HEART score is not used in obvious acute infarctions.
