Brief Summary

In patients with acute ST-elevation myocardial infarction (STEMI), 40-60% have multi-vessel disease with an increased cardiovascular morbidity and mortality. Although it is not recommended to revascularize noninfarct lesions during the acute intervention, recent investigations suggest the opposite and show improved outcome after direct revascularization of noninfarct lesions. It is undesirable to risk procedure-related complications by treating noninfarct lesions without impaired flow. It is currently unknown whether pressure guided revascularization of noninfarct lesions in the acute phase improves outcome compared to the current guidelines. The iMODERN trial aims to compare an iFR-guided intervention of noninfarct lesions during the acute intervention with a deferred stress perfusion CMR-guided strategy during the outpatient follow-up, to determine the optimal therapeutic approach for STEMI patients with multivessel lesions.
