HEART Score Calculator for Major Cardiac Events
Predicts 6-week risk of major adverse cardiac events (MACE) in patients with chest pain symptoms suggestive of acute coronary syndrome (ACS). Validated clinical decision support tool for emergency medicine and cardiology.
HEART Score Calculator
Use in patients ≥21 years old presenting with symptoms suggestive of ACS. Do not use if new ST-segment elevation ≥1 mm or other new EKG changes, hypotension, life expectancy less than 1 year, or noncardiac medical/surgical/psychiatric illness determined by the provider to require admission.

How to Use This Tool
Step-by-Step Guide
1. Patient Selection
Use for patients ≥21 years with symptoms suggestive of ACS. Exclude patients with new ST-segment elevation ≥1 mm, hypotension, or life expectancy <1 year.
2. Input Clinical Data
Select appropriate options for each of the 5 HEART score components: History, EKG, Age, Risk Factors, and Initial Troponin.
3. Calculate Score
Click "Calculate HEART Score" to compute total points (0-10) and determine risk category (Low, Intermediate, High).
4. Review Management
Based on the score, follow evidence-based clinical management recommendations and critical actions for optimal patient care.
Frequently Asked Questions
The HEART Score is a validated clinical decision tool that predicts the 6-week risk of Major Adverse Cardiac Events (MACE) in patients presenting with chest pain suggestive of Acute Coronary Syndrome (ACS). MACE includes myocardial infarction, coronary revascularization, and all-cause mortality. The score ranges from 0-10 points across five domains: History, EKG, Age, Risk Factors, and Troponin.
The HEART Score should not be used for patients with: new ST-segment elevation ≥1 mm or other new EKG changes requiring immediate intervention, hypotension (SBP <90 mmHg), life expectancy less than 1 year, or noncardiac medical/surgical/psychiatric illness determined by the provider to require admission regardless of cardiac risk. Also exclude patients with known STEMI who require immediate reperfusion therapy.
Low Risk (0-3 points): 0.9-1.7% risk of MACE at 6 weeks. Consider early discharge with follow-up.
Intermediate Risk (4-6 points): 12-16.6% risk of MACE. Admission for observation and further testing recommended.
High Risk (7-10 points): 50-65% risk of MACE. Immediate aggressive management and likely ICU admission required.
Use your institution's local, regular sensitivity troponin assays and corresponding cutoffs. Normal troponin = 0 points; 1-3× upper limit of normal = 1 point; >3× upper limit of normal = 2 points. For high-sensitivity troponin assays, consult specific institutional protocols as cutoff values differ. Recent evidence suggests using the same multipliers for hs-troponin may be appropriate but institutional guidelines should be followed.
The HEART Score helps emergency physicians and cardiologists risk-stratify patients with chest pain, potentially reducing unnecessary hospital admissions for low-risk patients while identifying high-risk patients who require aggressive management. It has been validated in multiple international studies and is incorporated into many chest pain clinical pathways. The score provides standardized risk assessment that can improve resource utilization and patient outcomes.
