iFR Guided Multi-vessel Revascularization During Percutaneous Coronary Intervention for Acute Myocardial Infarction (iMODERN)

August 12, 2026 updated by: Radboud University Medical Center

Instantaneous Wave-free Ratio Guided Multi-vessel revascularizatiOn During Percutaneous Coronary intervEntion for Acute myocaRdial iNfarction (iMODERN)

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Intervention:

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 3 years follow-up.

Duration:

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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
