    Duke Treadmill Score

    Diagnoses and prognoses suspected CAD based on the treadmill exercise test.
    When to Use
    Pearls/Pitfalls
    Why Use

    Patients without known coronary artery disease undergoing treadmill EKG testing.

    • Originally created using minutes of exercise under Bruce protocol.
    • Should be used with caution in patients undergoing testing with other protocols.
      • If alternative protocol used, consider equivalent in multiples of resting oxygen consumption (METs) instead of minutes of exercise.
    • Provides independent prognostic information in addition to coronary anatomy, left ventricular ejection fraction, and clinical data.
    • Unclear utility if any of the following are present: significant valvular or congenital heart disease, previous cardiac surgery, uninterpretable EKG due to left bundle branch block, ST-segment elevation in leads with pathologic Q waves.
    • Does not consider clinical variables such as age, heart rate, or blood pressure, which are known risk factors for CAD.

    Can provide diagnostic and prognostic information for patients with suspected coronary artery disease based on the treadmill exercise test.
