The study population consisted of 50 patients of both sexes, stratified into two groups: patients with myocardial ischemia detected by scintigraphy (group IP, n = 25) and healthy individuals (CG group, n = 25). In the patients who underwent scintigraphy with tomographic sections and presented any type of image attenuation during the examination, they also underwent a complementary prone position technique. Patients without these characteristics scintigraphy methodologies were excluded from the study.
