MULTivessel Immediate Versus STAged RevaScularization in Acute Myocardial Infarction -The MULTISTARS AMI Trial (MULTISTARS AMI)

January 9, 2024 updated by: University of Zurich

MULTivessel Immediate Versus STAged RevaScularization in Acute Myocardial Infarction - The MULTISTARS AMI Trial

The primary objective of the trial is to compare, in patients presenting with ST segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD), the safety and efficacy of immediate complete revascularization of all significant coronary lesions versus culprit vessel only revascularization and staged percutaneous coronary intervention (PCI) of all significant coronary lesions (within 19 to 45 days), in a non-inferiority trial using a third generation, biodegradable-polymer, everolimus-eluting stent.

Study Overview

Detailed Description

An investigator-initiated, randomized, multicenter, two-arm, open-label study of consecutive patients presenting with STEMI and MVD in stable hemodynamic conditions, undergoing after successful PCI of the culprit lesion either (1:1 randomization) immediate revascularization of all additional target lesions during the index procedure or staged PCI of all additional target lesions (within 19 to 45 days) using the Boston Scientific Synergy™ stent.

The goal of this trial is to compare two treatment strategies that are currently performed in clinical practice: immediate complete revascularization versus staged complete revascularization in patients with STEMI and MVD.

Patients randomized to immediate complete revascularization will have treated during the index procedure, after revascularization of the culprit lesion, all significant non-culprit coronary lesions.

Patients randomized to staged complete revascularization will have treated during the index procedure only the culprit lesion, and they will be hospitalized after 19-45 days for complete revascularization of all significant non-culprit coronary lesions.

For both groups, lesion are considered significant when causing a ≥70% diameter stenosis by visual estimation in at least two projections on the coronary angiogram.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Staged complete PCI
Patients randomized to staged complete PCI will have treated during the index admission only the culprit lesion and they will be hospitalized after 19-45 days, to complete the coronary revascularization on all the other significant coronary lesions. All the revascularizations will be performed with Synergy™ stent.
During the index procedure, patients will have treated with primary PCI the culprit lesion only. Patients will be hospitalized again after 19-45 days to undergo PCI of all the other significant coronary lesions. All the revascularizations will be performed with Synergy™ stent.
Bioabsorbable Polymer Drug-Eluting Stent
Experimental: Immediate complete PCI
Patients randomized to immediate complete PCI will have treated immediately after the revascularization of the culprit lesion during the index procedure all the other significant coronary lesions. All the revascularizations will be performed with Synergy™ stent.
Bioabsorbable Polymer Drug-Eluting Stent
During the index procedure, patients will have treated with primary PCI the culprit lesion, as well as all the other significant coronary lesions. All the revascularizations will be performed with Synergy™ stent.
