Regional dysfunction by equilibrium radionuclide angiocardiography: A clinicopathologic study evaluating the relation of degree of dysfunction to the presence and extent of myocardial infarction

The relation of degree of regional wall motion abnormality by equilibrium radionuclide angiocardiography to the presence and mural extent of regional necrosis or scar at autopsy was evaluated in 23 autopsy patients who had a history of myocardial infarction and had equilibrium radionuclide angiocardiography within 40 days of death. Of the 228 regions evaluated by equilibrium radionuclide angiocardiography, 135 had abnormal regional wall motion and 102 (76%) of these 135 regions had evidence of myocardial infarction at autopsy. The overall sensitivity, specificity and predictive values of regional wall motion abnormality for regional necrosis or scar were 69, 59 and 76%, respectively.
