Dobutamine Stress Myocardial Perfusion Imaging: Expect the Unexpected

Authors: Elsayed Z. Soliman, MD, MSc

Abstract

Dobutamine stress myocardial perfusion imaging (DSMPI) is a pharmacologic stress test in combination with radionuclide myocardial perfusion imaging. DSMPI is the alternative method for evaluation of patients with known or suspected coronary artery disease who are unable to perform adequate exercise testing, and who also have contraindications to the vasodilators adenosine and dipyridamole pharmacologic stress testing because of severe obstructive airway disease, high-grade atrioventricular block, or marked hypotension.1,2
