We assessed the prognostic value of intravenous dipyridamole stress testing with technetium-99m sestamibi single-photon emission computed tomographic myocardial perfusion imaging for 512 patients with suspected coronary artery disease referred for testing. Patients with an abnormal perfusion result had significantly more cardiac events (cardiac death or nonfatal myocardial infarction) than did those with a normal study result. In addition, defect size was strongly associated with the incidence of cardiac events and cardiac-related hospitalization. The findings of this study demonstrate that dipyridamole stress with technetium-99m sestamibi tomographic imaging can accurately stratify patients who cannot undertake exercise testing into low- and high-risk subgroups.
