- 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 ?
- Compared with nuclear imaging – stress echocardiography equally sensitive and specific.
- 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?
- Presence of previous infarcted segments
- Known multivessel CAD
- Left bundle branch block may
Because of difficulty interpreting wall thickening in the presence of resting regional dysfunction and translational motion.
