HEART Score Calculator

How to Use the HEART Score Calculator

To calculate the HEART score, you need to enter:

• Age (years): Specify the patient's age.
• ECG Findings: Choose from normal, non-specific, or significant ST deviation.
• History: Assess the type of chest pain (typical, non-typical, or mixed).
• Initial Troponin Levels: Measure troponin levels and compare them to the normal lab range.
• Risk Factors: Include factors like coronary artery disease (CAD), diabetes, dyslipidemia, or hypertension. (You can mention 1 0r 3+ risk factors in number in the box)

The calculator adds up these values to provide a HEART score ranging from 0 to 10.

Healthy vs. Unhealthy Ranges

The HEART score categorizes patients into risk groups for MACE:

• Low Risk (0-3): 2% chance of MACE. Patients can often be discharged early.
• Moderate Risk (4-6): ~13% chance of MACE. Further observation or testing is needed.
• High Risk (7-10): ~50% chance of MACE. Requires urgent intervention and hospitalization.

Why Use the HEART Score Calculator?

This tool helps stratify patients based on their cardiovascular risk:

• Avoids unnecessary hospitalizations: Reduces strain on emergency departments.
• Ensures timely care: High-risk patients receive immediate intervention.
• Evidence-based decisions: Uses validated criteria to support clinical judgment.

Results Interpretation

HEART Score Example: Jake, a 71-year-old patient, presented with chest pain and the following findings:

• Age: 71 (2 points)
• ECG: Abnormal with known ST deviation (1 point)
• History: Mixed chest pain elements (1 point)
• Initial Troponin: Elevated 1.5x the normal range (1 point)
• Risk Factors: Diabetes and hypertension (1 point)

HEART Score: 6 (Moderate Risk)
Jake requires further testing and observation for potential cardiac events.

What is MACE?

MACE stands for Major Adverse Cardiovascular Events, including:

• All-cause mortality
• Acute myocardial infarction (AMI)
• Need for percutaneous coronary intervention (PCI)
• Coronary artery bypass graft (CABG)
• Death within six weeks

Risk Factors for MACE Include:

• Coronary artery disease (CAD)
• Age >65
• Coronary stenosis
• Dyslipidemia
• Diabetes mellitus
