Abstract
Myocardial perfusion/function scintigraphy is an effective means of recognizing and treating patients with acute myocardial infarction or unstable angina. Technetium Tc99m sestamibi or tetrofosmin can be injected in the emergency department during chest pain, and imaging can be performed up to 4 hours later. Patients whose chest pain has resolved before injection can be evaluated initially with a resting thallium-201 study, followed by a stress sestamibi or tetrofosmin study if the thallium-201 scan is normal. Combined evaluation of ventricular function and myocardial perfusion minimizes the false-negative rate in the detection of acute coronary syndromes. Nuclear techniques also have been shown to be useful in the assessment of prognosis for patients with acute coronary disease, in the selection and evaluation of therapy, and in discharge planning.
