To determine the accuracy of two-dimensional echocardiography (2-D echo) for assessment of exercise-induced wall motion abnormalities in patients with coronary artery disease, the results of stress echocardiography were compared with exercise cineventriculography. In 56 consecutive patients, biplane cineventriculography at rest and immediately after supine bicycle exercise was performed. Cross-sectional echo was obtained using the apical two- and four-chamber-views for left ventricular imaging under identical conditions. In 6 of the 56 patients 2-D echo, in 8 patients cineventriculogram, and in 2 patients both methods were of inadequate quality at rest or during exercise. Of the remaining 40 patients, 34 had coronary artery disease. Local wall motion in 360 wall segments from these patients was analyzed. In 49 segments (14%) in 24 of these patients exercise-induced ischemic wall motion abnormalities were evident during cineventriculography. Only 24 of these 49 asynergies (49%) were also recognized by 2-D echo. Using cross-sectional echocardiography, ischemia-related wall motion abnormalities were best detected septal, whereas apical asynergies were identified in only 3 of 12 segments (25%). Thus, the clinical value of exercise 2-D echo as a screening method in patients suspected of having coronary artery disease is limited and restricted to patients where excellent visualization of the left ventricular endocardium is possible.
