Usefulness of myocardial circunferential strain in acute myocardial infarction for prediction of contractile function recovery: a MRI myocardial tagging study

Background In patients (p) with acute myocardial infarction (AMI), quantitation of myocardial regional function may be useful to differentiate between stunned and necrotic myocardium and to predict ventricular function recovery during follow-up. Different parameters exist to evaluate regional myocardial function such as circunferential /radial strain and displacement. The purpose of this study is to determine the most useful parameter for prediction of contractile function recovery obtained from tagged MRI.
