Contributor: Taylor Lynch, MD 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
