Abstract

Myocardial perfusion imaging (MPI) is a useful noninvasive test for the evaluation of patients following acute myocardial infarction (AMI). Early (2–3 days postadmission) pharmacological stress or pre-discharge exercise MPI in patients with uncomplicated AMI is safe and provides important prognostic information of the risk of subsequent cardiac events. The most powerful predictors of prognosis (total defect size, extent of reversibility and resting left ventricular ejection fraction) can be assessed with a single non-invasive test employing gated single photon emission computed tomography (gated-SPECT) technology.

Key Words: Myocardial perfusion imaging • acute myocardial infarction • risk assessment
