RESUMO
El estudio gated-SPECT de perfusión miocárdica es una técnica utilizada e indicada para la valoración de los pacientes con un diagnóstico no claro de cardiopatía isquémica. El estudio gated-SPECT de reposo precoz en fase aguda tiene una alta sensibilidad y alto valor predictivo negativo para descartar enfermedad coronaria. Presentamos el caso de una paciente ingresada para el estudio de dolor torácico, a la que se le realizó un estudio de perfusión miocárdica de esfuerzo-reposo, cuyo resultado podría haber sido equívoco debido al estado clínico de la paciente durante la inyección del radiofármaco (AU)
Gated-SPECT myocardial perfusion imaging is a widely used technique indicated for assessment of patients with no clear diagnosis of ischemic heart disease. Early rest gated-SPECT myocardial perfusion study in patients with acute chest pain has high sensitivity and high negative predictive value for ruling out coronary disease. We report a case of a patient admitted for the study of her chest pain. She underwent a myocardial perfusion stress-rest whose interpretation could have been equivocal due to the clinical status of the patient during the injection of the radiotracer (AU)
