Coronary Vasospasm Produces Reversible Perfusion Defects Observed During Adenosine Triphosphate Stress Myocardial Single‐photon Emission Computed Tomography

摘要

BackgroundAdenosine triphosphate stress thallium‐201 single‐photon emission computed tomography (ATP‐SPECT) is useful for diagnosing coronary artery disease (CAD), although sometimes false positive results are observed. It has not been established whether a coronary spasm is responsible for the false positive findings during ATP‐SPECT.
