How to calculate

Adds up the HEART score for chest pain (Six 2008) from history, ECG, age, risk factors, and troponin to a total of 0 to 10, and shows the band and the rate of cardiac events the original study found.

Example with the default inputs (History Slightly suspicious (0), ECG Normal (0), Age 50, Risk factors None known (0), Troponin At or below the normal limit (0)): The HEART score is 1 (Low); in the 2008 study, 2.5% of such patients had a major cardiac event.

Method: HEART = History + ECG + Age + Risk factors + Troponin, each 0 to 2 (total 0 to 10). Low 0 to 3, moderate 4 to 6, high 7 to 10.

  • For adults seen in the emergency department with chest pain, as in Six 2008 (120 patients in one hospital).
  • Troponin points follow Six 2008 (1 to 2 times, over 2 times the normal limit). Some later tables use 3 times the limit as the upper cutoff.
  • The rate is what the 2008 study observed in each band, not a personal prediction.

  1. History Slightly suspicious (0), ECG Normal (0), Age 50, Risk factors None known (0), Troponin At or below the normal limit (0) gives HEART score 1, Band Low, Event rate in the 2008 study 2.5%, Age points 1.Source: Six 2008 Table 1: age 45 to 65 scores 1
  2. History Highly suspicious (2), ECG Nonspecific repolarization changes (1), Age 66, Risk factors 1 or 2 risk factors (1), Troponin At or below the normal limit (0) gives HEART score 6, Band Moderate, Event rate in the 2008 study 20.3%, Age points 2.Source: Six 2008: 2 + 1 + 2 + 1 + 0 = 6, band 4 to 6 had 20.3% events

When this does not apply. The score is for adults in an emergency department with chest pain that might come from the heart. It does not apply to a clear heart attack on the ECG (ST elevation), to people who are unstable, or outside a hospital setting.

HEART score = the sum, 0 to 10 (Six 2008, Table 1). Age is entered in whole years, 18 to 120.

Bands and the event rates of Six 2008: 0 to 3 low (2.5%), 4 to 6 moderate (20.3%), 7 to 10 high (72.7%). The rate is shown with 1 decimal.

Worked examples by hand

Page default. Age 50 scores 1; everything else 0. Total 1, low, 2.5%.

Moderate. History 2, ECG 1, age 66 (2), 1 or 2 risk factors (1), troponin normal (0): 6, moderate, 20.3%.

High. 2 + 2 + age 70 (2) + 2 + troponin 1 to 2 times (1) = 9, high, 72.7%.

Under 45. History 1, ECG 0, age 44 (0), risk 1, troponin 1: 3, low.

Age 65. History 1, ECG 1, age 65 (2), risk 0, troponin 0: 4, moderate.

Other questions people ask

What is the HEART score?

A score for people seen in an emergency department with chest pain, published by Six, Backus, and Kelder in 2008. HEART stands for History, ECG, Age, Risk factors, and Troponin. Each scores 0, 1, or 2, for a total of 0 to 10.

What do the bands mean?

In the 2008 study of 120 patients, major cardiac events (heart attack, a procedure to open the heart arteries, or death) happened in 2.5% of those scoring 0 to 3, 20.3% of those scoring 4 to 6, and 72.7% of those scoring 7 to 10.

Which risk factors count?

Diabetes, smoking, high blood pressure, high cholesterol, a family history of heart disease, and obesity (Six 2008). A history of atherosclerotic disease scores 2 on its own.

How is troponin scored?

In the 2008 paper: at or below the normal limit 0, 1 to 2 times the limit 1, over 2 times 2. Some later tables use 3 times the limit as the upper cutoff. This page follows the 2008 paper, because its event rates belong to its own troponin bands.

How is age scored?

Under 45 scores 0, 45 to 64 scores 1, and 65 or more scores 2. Six 2008 Table 1 prints 45 to 65 for 1 point, but the Methods of the same paper give 2 points at 65 years or older; this page follows the Methods.

Do later studies give the same rates?

No. Larger studies found lower rates in each band (for example Backus 2013 in 2,440 patients), so the 2008 numbers describe that first study, not a personal risk.
