Evaluation of Cardiac Magnetic Resonance as a Surrogate in ST-Segment Elevation Myocardial Infarction

Cardiac magnetic resonance imaging is an attractive noninvasive metric and has genuine potential to constitute a reliable surrogate end point in ST-elevation myocardial infarction. However, these measures must be demonstrated as a valid proxy to predict clinical outcome. In conclusion, the current review evaluates the utility of cardiac magnetic resonance as a surrogate measurement of myocardial infarct size, left ventricular function, microvascular obstruction, and myocardial salvage in ST-elevation myocardial infarction exploring the temporal relations specific to each assessment.
