Definition of Multivessel Disease

For AEGIS-II inclusion criteria #5, multivessel disease criteria can be met by findings on the cardiac catheterization for the index MI, a prior cardiac catheterization, or both:

• Index MI cardiac catheterization: 50% or greater stenosis of the left main or at least 2 coronary artery territories (LAD, LCX, RCA) (prior to any interventions performed)
• Prior cardiac catheterization: 50% or greater stenosis of left main or at least 2 coronary artery territories (LAD, LCx, RCA) (prior to any interventions performed)
• Both: Index MI cardiac catheterization with 1 vessel with 50% or greater stenosis (prior to any interventions performed) AND prior PCI of at least 1 vessel different from index MI vessel
• Prior multivessel CABG

Multivessel disease requires a 50% or greater stenosis in at least 2 of the 3 major epicardial artery territories (LAD, LCx, RCA) or the left main vessel. Branch vessel disease may qualify as part of the territory of that branch vessel (for example, a diagonal vessel is considered part of the LAD territory). For the purpose of this study, the ramus is considered part of the Left Circumflex artery territory. If a branch vessel is used as a qualifying vessel, that branch should be of large enough size to potentially undergo revascularization if clinically indicated, e.g. >2mm vessel size.

To determine if your patient meets the eligibility criteria for multivessel disease, please check all arteries/segments with 50% or greater stenosis on the cardiac catheterization for index MI and/or vessels that have received prior PCI (stent or balloon angioplasty).
