Comparison of Prognostic Value of Negative Dobutamine Stress Echocardiography Versus Single-Photon Emission Computed Tomography After Acute Myocardial Infarction

We enrolled 196 patients who had myocardial infarction and no ischemia on dobutamine stress echocardiography (DSE) and/or single-photon emission computed tomography (SPECT). Negative studies were observed in 125 patients on DSE and in 159 on SPECT. Patients were followed for 43 ± 14 months. Cardiac...

Summary:We enrolled 196 patients who had myocardial infarction and no ischemia on dobutamine stress echocardiography (DSE) and/or single-photon emission computed tomography (SPECT). Negative studies were observed in 125 patients on DSE and in 159 on SPECT. Patients were followed for 43 ± 14 months. Cardiac events occurred in 14% of patients who did not have ischemia on DSE and in 9% of patients who did not have ischemia on SPECT. Event-free survival rate was higher in the presence of negative findings on SPECT compared with DSE (p <0.05). The lack of residual myocardial ischemia on SPECT identifies patients at low risk of events, and a negative finding on stress SPECT is superior to a negative finding on DSE.
