Key result
Exercise 2D echo detects only ~49% of ischemic wall motion abnormalities seen on cineventriculography.
Why the study?
The accuracy of two-dimensional echocardiography for detecting exercise-induced wall motion abnormalities in patients with coronary artery disease was uncertain.

Exercise 2-D echo detects fewer ischemic wall motion changes than cineventriculography; leaves open its screening utility pending modern validation studies.

Does two-dimensional echocardiography accurately detect exercise-induced wall motion abnormalities compared to biplane cineventriculography in patients with coronary artery disease?
Exercise 2-D echocardiography has limited sensitivity (49%) for detecting exercise-induced wall motion abnormalities compared to cineventriculography, restricting its clinical value as a screening tool to patients with excellent acoustic windows.
Voelker et al. (1988) conducted a cross-sectional in Coronary artery disease (n=56). Two-dimensional echocardiography (2-D echo) vs. Biplane cineventriculography was evaluated on Detection of exercise-induced ischemic wall motion abnormalities. Two-dimensional echocardiography detected only 49% of exercise-induced ischemic wall motion abnormalities identified by biplane cineventriculography in patients with coronary artery disease.
