Adenosine Stress/Rest Myocardial Perfusion Single-Photon Emission Computed Tomography

Adenosine Stress/Rest Myocardial Perfusion Single-Photon Emission Computed Tomography

Case example illustrating value of stress testing ST when rest myocardial perfusion imaging is normal in the acute chest pain patient. Shown are adenosine stress/rest myocardial perfusion single-photon emission computed tomography images in a 55-year-old man with multiple risk factors for coronary artery disease presenting to the emergency department with 2 days of chest discomfort at rest. Rest sestamibi (MIBI) demonstrated minimal (borderline) perfusion defect in the inferior wall. Stress imaging revealed evidence of severe and extensive ischemia in the inferior and inferolateral wall (41% of the left ventricle). Coronary angiography revealed an occluded right coronary artery that was successfully stented.
