Predicting MRI-diagnosed microvascular obstruction and its long-term impact after acute myocardial infarction.

Background: Microvascular obstruction (MVO) at cardiac magnetic resonance imaging (CMR) is a well-described risk factor for cardiac events after acute myocardial infarction (MI).

Objective: Predicting MVO using cardiac biomarkers and performing risk stratification according to extent of MVO.

Methods: We conducted a retrospective study including all patients with an acute MI and a subsequent CMR during the same hospital stay between October 2008 and August 2023.
