HEART Score – yes, AGAIN! going to keep mentioning it until everyone uses it!

The HEART score is a risk stratification score for identifying the risk of a Major Adverse Coronary Event (MACE) within 6 weeks of presentation that has been validated for the ED population.  (MACE defined as: All Cause Mortality, Myocardial Infarction, or Coronary revascularization).  All those framingham risk factors that we are forced to memorize and that cardiologists always ask about?  They mean almost nothing for ED patients.  Wonderful for the patients who go to their PCP’s on a regular basis, but in terms of people who present to the ED, using risk factors as the sole predictor of badness is probably worse than just flipping a coin.

Well, about about TIMI score?  Isn’t that validated?  YES, it is validated, but doesn’t perform nearly as well for ED patients as the HEART score.  Also, TIMI was derived for  “patients admitted and anticoagulated for concerning chest pain in the setting of ECG changes, known coronary artery disease, or positive biomarkers. The original predictive value of the TIMI Score was intended to prognosticate 14-day mortality or new cardiac ischemia for cardiac inpatients.” (ACEP Now).  I’m pretty sure all of us can stratify patients as moderate to high risk if they are already admitted and on anticoagulation.

Backus et. al compared the c-statistic of the HEART Score, GRACE Score, and TIMI for ED patients.  A c-statistic is used to predict the probability that an outcome is greater than chance.  Values are from 0.5 – 1.0, with a value of 0.5 meaning it is no better than chance. 0.7 is considered a reasonable score and 0.8 is considered strong.

GRACE: 0.70

TIMI: 0.75

HEART: 0.83

So basically GRACE is okay, but so complex to use and so many variables that it’s nearly impractical to use.  TIMI was derived initially for patients with known ACS, but has been found to be acceptable to use for ED patients.

But the HEART score was created specifically to be used for ED patients, AND it outperforms the other scores.

There is also the EDACS (Emergency Department Assessment of Chest Pain Score) that may outperform the HEART score, but I personally find it to have too many variables.  Not nearly as many as GRACE, but still a lot.  Click Here if you want to play around with it.

If you have not memorized the HEART score, This link can help you out.

I have also added a smart phrase in epic (.HEARTSCORE) for everyones convenience.  Please let me know if it does not work for you.

  1. Very interested in the heartscore smart phrase. Are you able to upload it to the site (or comment section)? Keep up the good work!

    • Sure, feel free to use it (it’s adapted from MDCalc’s website)
      HEART Score for Major Cardiac Events: ____

      History: ___
      EKG: ___
      Risk Factors: ___
      Troponin: ___

      History (0 = Slightly Suspicious; 1 = Moderately Suspicious; 2= Highly Suspicious)
      EKG: (0 = Normal EKG; 1 = Nonspecific repolarization disturbance; 2= Significant ST depression)
      Age: (0= 65)
      Risk Factors (0 = 0-1 RF; 1 = 1-2 RF’s; 2= 3 or more RF’s, OR known history of CAD)
      Troponin: (0=Normal; 1= 1-3x upper limit of normall; 2= >3x upper limit of normal)

      Risk Factors for CAD: Hypercholesterolemia, HTN, DM, Smoking, Positive Family History, Obesity

      HEART Score predicts major adverse cardiac events within 6 weeks (All Cause Mortality, MI, or Coronary revascularization)

      0-3: 1.7% risk of MACE
      4-6: 12-16% risk of MACE
      7-10: 50-65% risk of MACE
