Educational Pearls:

How do we risk-stratify chest-pain patients?

One option is the HEART score
- This score predicts a patient’s 6-week risk of a major adverse cardiac event.
  - Ex. Cath procedure, CABG, PCI, death
H stands for History
- Ask 1) Was the patient diaphoretic? 2) Did they have nausea and/or vomiting? 3) Did the pain radiate down the right or left arm? 4) Was it exertional?
- Yes to one = one point. Two or more = two points.
E stands for EKG
- One point for left ventricular hypertrophy, t-wave inversions, new bundle-branch blocks.
- No points for first degree AV block, benign early repolarization, or QT-prolongation
- Two points for ST-depression
A stands for Age
- >65 gets two points
- 45-64 gets one point
R stands for Risk factors
- Hypertension, hyperlipidemia, diabetes, obesity, family history, smoking, previous MI, previous CABG, stroke, peripheral arterial disease
- 1-2 risk factors get 1 point
- More than two risk factors gets two points
T stands for Troponin
- 1-3x upper limit of normal gets one point
- >3x upper limit of normal gets two points
This gives you a score between zero and ten
- 0-3 points, patients have a ~2% chance of an adverse event
  - These patients likely go home
- 4-6 points, patients have a ~20% chance of an adverse event
  - These patients get admitted or expedited outpatient stress test/echo
- 7-10 points, patients have a ~60% chance of an adverse event
  - Admit and call cardiology.
  - These patients likely get catheterized
