To compare the value of exercise electrocardiography with dobutamine stress echocardiography and exercise technetium-99m isonitrile single-photon emission computed tomography for coronary artery disease, 70 patients with either suspected or proven coronary artery disease underwent dobutamine stress echocardiography, exercise technetium-99m isonitrile single-photon emission computed tomography (mibi-SPECT) and treadmill exercise electrocardiography (EGG). Dobutamine echocardiography and exercise mibi-SPECT revealed a higher overall sensitivitiy than exercise testing (90 vs 57%, p < 0.001; 96 vs 57%, P < 0.001, respectively). Dobutamine stress echocardiography showed a higher specificity than both exercise mibi-SPECT and treadmill exercise electrocardiography (90 vs 71%, P > 0.05; 90 and 62% p < 0.05, respectively) but the difference between dobutamine stress echocardiography and exercise mibi-SPECT was not statistically significant. Diagnostic accuracy of dobutamine stress echocardiography and exercise mibi-SPECT was higher than that of exercise testing (90 vs 59%, P < 0.001; 89 vs 59%, P < 0.001, respectively).
