%X thoracic pain is a common symptom in emergency services, and stress radionuclide imaging represents one of the phases of risk stratification in these individuals. however, a group of patients with negative functional exams after physical or pharmacological stress develops myocardial ischemia during this psychological stress. alterations in vascular tonus as a response to endogenous mechanisms are the physiopathologic basis for such alterations. we report a case that illustrates how mental stress radionuclide imaging has the potential to be used in the assessment of myocardial ischemia non-detected by conventional methods in patients with suspicion of ischemic thoracic pain.
