Stress echocardiography

Stress echocardiography

  1. Stress echocardiography – using either treadmill, bicycle, or pharmacologic (dobutamine or vasodilator)
  2. Stress echocardiography has proved to be more accurate than the exercise ECG alone for diagnosing flow-limiting CAD, particularly in women and patients with LV hypertrophy.

What are the advantages of Stress Echocardiography ?

  1. Compared with nuclear imaging – stress echocardiography equally sensitive and specific.
  2. In the same examination. allow simultaneous assessment of
    • Hemodynamics,
    • Valvular disease
    • Estimation of pulmonary artery systolic pressures

Which factors decrease the sensitivity and specificity of stress echocardiography?


  1. Presence of previous infarcted segments
  2. Known multivessel CAD
  3. Left bundle branch block may

Because of difficulty interpreting wall thickening in the presence of resting regional dysfunction and translational motion.
