HEART Score Calculator

About the HEART Score Calculator

The HEART Score Calculator assesses the risk of major adverse cardiac events (MACE) within 6 weeks for patients presenting with chest pain in the emergency department. It uses five criteria: History, ECG, Age, Risk factors, and Troponin levels.

Calculation: Each criterion is scored from 0 to 2, and the total score (0–10) determines the risk category: Low (0–3), Moderate (4–6), or High (7–10).

Use this tool for educational purposes or to assist in clinical decision-making, but always consult a healthcare provider.

• Features:
  • Calculates HEART Score based on:
    • History: Slightly suspicious (0), Moderately suspicious (1), Highly suspicious (2)
    • ECG: Normal (0), Non-specific repolarization disturbance (1), Significant ST deviation (2)
    • Age: <45 years (0), 45–64 years (1), ≥65 years (2)
    • Risk Factors: 0 (0), 1–2 (1), ≥3 or CAD history (2)
    • Troponin: Normal (0), 1–3× normal limit (1), >3× normal limit (2)
  • Displays calculations and risk categories in LaTeX format.
  • Clear and copy functionality.
  • Uses MathJax for professional rendering of mathematical expressions.
• Practical Applications: Used in emergency departments to stratify chest pain patients for risk of MACE, guiding decisions on admission or discharge.
• How to Use:
  • Select the appropriate option for History.
  • Select the appropriate option for ECG findings.
  • Select the patient’s age range.
  • Select the number of risk factors or CAD history.
  • Select the troponin level.
  • Click "Calculate" to view the HEART Score and risk category.
  • Use "Clear" to reset selections.
  • Use "Copy Results" to copy the results.
  • Share or embed the calculator using the action buttons.
• Helpful Tips:
  • Risk factors include hypertension, hypercholesterolemia, diabetes, obesity (BMI >30), smoking, family history of CAD, or personal history of atherosclerosis.
  • Troponin levels should be based on high-sensitivity assays where available.
  • Low-risk patients (0–3) may be considered for discharge with follow-up.
  • Moderate (4–6) or high-risk (7–10) patients typically require further evaluation or admission.
  • Results are estimates and not a substitute for professional medical advice.
• Formula:
  • Total Score: \\( S = S_H + S_E + S_A + S_R + S_T \\)
  • Risk Category:
    • 0–3: Low risk (1.7% MACE)
    • 4–6: Moderate risk (20.3% MACE)
    • 7–10: High risk (72.7% MACE)
• Examples:
  • Example 1: 50-year-old with moderately suspicious history, normal ECG, 1 risk factor, normal troponin:
    • Inputs: History = Moderately suspicious (1), ECG = Normal (0), Age = 45–64 years (1), Risk Factors = 1–2 (1), Troponin = Normal (0)
    • Steps:
      • Score: \\( S = 1 + 0 + 1 + 1 + 0 = 3 \\)
      • Risk: Low (1.7% MACE risk)
    • Result: HEART Score = 3 (Low risk)
  • Example 2: 70-year-old with highly suspicious history, ST deviation, 3 risk factors, elevated troponin:
    • Inputs: History = Highly suspicious (2), ECG = Significant ST deviation (2), Age = ≥65 years (2), Risk Factors = ≥3 or CAD (2), Troponin = >3× normal limit (2)
    • Steps:
      • Score: \\( S = 2 + 2 + 2 + 2 + 2 = 10 \\)
      • Risk: High (72.7% MACE risk)
    • Result: HEART Score = 10 (High risk)
