Measure
Single Vessel Disease, Not Randomized
Standard of care comparator for those subjects with single vessel coronary artery disease who were not randomized. Revascularization with Medtronic Resolute family of stents in infarct related artery; Possible use of Terumo Glidesheath Slender and Terumo TR Band Radial Compression Device.
Randomized to IRA Group
Participants randomly assigned to receive a coronary procedure involving evaluation by iFR to implant stents into multiple arteries (primary and others that are partially blocked). The Randomized to IRA group mainly includes participants with Multi-Vessel Disease, with the addition of two participants with single vessel disease (SVD) who were erroneously randomized to the IRA group and included in the intent-to-treat (ITT) population analyses.
Randomized to iFR Group
Participants randomly assigned to receive a coronary procedure involving evaluation by iFR to implant stents into multiple arteries (primary and others that are partially blocked). The Randomized to iFR group mainly includes participants with Multi-Vessel Disease, with the addition of two participants with single vessel disease (SVD) who were erroneously randomized to the iFR group and included in the intent-to-treat (ITT) population analyses.
Multi-vessel CAD, Non-randomized
Participants who had contraindications to performing the randomized procedure.

PRIMARY outcome

Timeframe: 1 year

Population: Per SAP, all eligible enrolled participants who used Medtronic Drug Eluting stent during at least one CathPCI are included in this analysis. The rationale for the Metronic analysis population is that all subjects were intention-to-treat with a Resolute-family stent. So a study participant would have received the Medtronic stent for STEMI regardless of whether they were in the single-vessel, multivessel, or multivessel with FFR arm.

Defined as cardiac death, infarct artery target-vessel MI, or ischemia-driven index infarct related vessel revascularization (IIVR) by percutaneous or surgical methods.

Timeframe: 30 days (>24hr to 30 days post stent)

Population: Per SAP, all eligible enrolled participants who used Medtronic Drug Eluting stent during at least one CathPCI are included in this analysis. The rationale for the Metronic analysis population is that all subjects were intention-to-treat with a Resolute-family stent. So a study participant would have received the Medtronic stent for STEMI regardless of whether they were in the single-vessel, multivessel, or multivessel with FFR arm.

Population: The outcome required several parameters from medical records to determine access success. However, these parameters were not collected before the study termination, therefore, this Outcome Measure was not collected.
