Background

Clinical Features

Risk of Acute Coronary Syndrome

Clinical factors that increase likelihood of ACS/AMI:[3][4]

  • Chest pain radiating to both arms > R arm > L arm
  • Chest pain associated with diaphoresis
  • Chest pain associated with nausea OR vomiting
  • Chest pain with exertion that is improved with rest

Clinical factors that decrease likelihood of ACS/AMI:[5]

  • Pleuritic chest pain
  • Positional chest pain
  • Sharp, stabbing chest pain
  • Chest pain reproducible with palpation

Gender differences in ACS

  • Women with ACS:
    • Less likely to be treated with guideline-directed medical therapies[6]
    • Less likely to undergo cardiac catheterization[6]
    • Less likely to receive timely reperfusion therapy[6]
    • More likely to report fatigue, dyspnea, indigestion, nausea or vomiting, palpitations, or weakness,[6] although some studies have found fewer differences in presentation[7]
  • More likely to delay presentation[6]
  • Men with ACS:
    • More likely to report central chest pain

Factors associated with delayed presentation[6]

  • Female sex
  • Older age
  • Black or Hispanic race
  • Low educational achievement
  • Low socioeconomic status
  • Key historical features to assess:
    • Quality: crushing/pressure (ACS), tearing/ripping (dissection), pleuritic/sharp (PE, pericarditis, pneumothorax)
    • Radiation: jaw/arm (ACS), back (dissection), shoulder (pericarditis)
    • Onset: sudden (PE, dissection, pneumothorax) vs gradual (ACS, musculoskeletal)
    • Associated symptoms: diaphoresis, dyspnea, nausea/vomiting, syncope
    • Risk factors: cardiac history, DVT/PE risk factors, cocaine use, connective tissue disease, recent procedure
  • Red flags:
    • Hemodynamic instability
    • New ECG changes (ST elevation/depression, new LBBB)
    • Unequal blood pressures or pulses (aortic dissection)
    • Tracheal deviation, absent breath sounds (tension pneumothorax)
    • Subcutaneous emphysema (pneumomediastinum, esophageal perforation)

Nonemergent

Evaluation

Workup

  • All patients:
    • ECG - within 10 minutes of arrival; repeat if symptoms change or initially nondiagnostic
    • CXR
    • Vital signs including bilateral blood pressures if dissection suspected
  • Moderate-to-high risk or concerning features:
    • Troponin - serial troponins (0h and 1-3h with high-sensitivity assay; 0h and 3-6h with conventional assay)
    • CBC, BMP
    • Consider coagulation studies
  • Additional testing based on suspicion:

Risk Stratification

  • HEART Score: Validated tool for risk stratification in undifferentiated chest pain
    • Score 0-3: Low risk; consider early discharge
    • Score 4-6: Moderate risk; admission/observation with serial troponins
    • Score 7-10: High risk; admission with cardiology consultation
  • Wells score: For pretest probability of PE
  • PERC rule: If low pretest probability, PERC can exclude PE without D-dimer

Management

Disposition

  • Admit to ICU/monitored bed:
    • STEMI, unstable ACS, hemodynamically significant PE, aortic dissection, pericardial tamponade
  • Admit/observe:
    • Moderate HEART score with pending serial troponins
    • NSTEMI awaiting cardiology evaluation
  • Discharge:
    • Low HEART score (0-3) with negative serial troponins
    • Clear non-cardiac cause identified (e.g., musculoskeletal, GERD)
    • PE ruled out with validated approach
    • Arrange appropriate follow-up (PCP within 72 hours for intermediate-risk patients)

HEART Score / 10
Interpretation
0–3 Low Risk — 0.9–1.7% risk of MACE. Consider discharge with outpatient follow-up.
4–6 Moderate Risk — 12–16.6% risk of MACE. Consider admission for observation and further workup.
7–10 High Risk — 50–65% risk of MACE. Consider early invasive measures (cardiology consult, catheterization).
