TEACHING POINTS

 We describe and review CMRI features in myocardial infarction. Evaluate CMRI endpoints with clinical and prognostic implication, with focusing on ischemia-reperfusion injury.  

TABLE OF CONTENTS/OUTLINE

 We review MRI findings of myocardial infarction, specially focusing on patients with AMI and reperfusion therapy.  We evaluate area at risk, infarct size,  salvaged myocardium and reperfusion injury and assess cardiac function and volumes. T2* CMR  detected  hemorrhage.   Infarct size and myocardial salvage are surrogate endpoints for mortality in the setting of myocardial infarction.  Regions of no enhancement  or maintained perfusion defects were areas of no-reflow, MO/hemorrhage. First-pass and early gadolinium enhancement  techniques are more sensitive than LGE. We detected MO in  patients with transmural infarcts or an affectation of at least 75% of  wall thickness. MRI is the best imaging technique to detect the presence of hemorrhage.   Infarct size, transmural infarction and persistent MO are strong predictors of adverse post-infarct remodeling over other clinical parameters.  MRI is especially adequately to study and follow up myocardial infarcts and its potential complications.
