Does post-STEMI CMR play a role in prognostication?

Elevated native T1 values are independent predictors of obstructive Non-IR artery in ST elevation MI patients. These results suggest the presence of concomitant remote myocardial impairment in the non-infarct territories wit obstructive CAD. The fact that there is a correlation between the presence of obstructive coronary artery and high native T1 values might support the performance of complete revascularization early after STEMI without postponing and waiting for the results of perfusion studies. As opposed to myocardial perfusion imaging, native T1 evaluation can be performed safely early post STEMI, not exposing patients to pharmacologic or physiologic stress. Therefore, larger and more comprehensive studies are needed to clarify the usefulness of revascularization of elevated T1 areas early after MI.
