Clinical Trial 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.

Clinical Trial Description

Study design:

The study is a prospective, randomized controlled, multicentre study.

Study population:

The research population will be recruited from the general patient population presenting with an acute STEMI. Patients treated with successful primary PCI and one or more additional significant coronary lesions in another coronary artery will be enrolled in the study. A total of 1,146 consecutive patients will be included.


The patients will be randomized 1:1, to (A) an active treatment arm with complete, iFR-guided revascularization of every noninfarct coronary lesion >50% and iFR ≤0.89; (B) a deferred treatment arm, in which patients will undergo an adenosine stress perfusion CMR scan within 6 weeks after STEMI, with revascularization of the noninfarct coronary lesions with associated perfusion defects.

Main study parameters/endpoints:

The primary end point consists of a combined outcome, including all-cause death, recurrent MI and hospitalization for heart failure at 12 months follow-up.


Anticipated recruitment is 2 years. Follow-up will be performed at 6 months, 12 months, 3 years and 5 years. ;
