7.0 Reporting of Adverse Events or Unanticipated Problems involving Risk to Participants or Others This study deviates from standard of care in that one additional, not clinically indicated PET stress test, will be performed soon after mechanical revascularization. Adverse events or unanticipated problems will be reported to Robert Bober, MD or Fahad Javed, MD at 504-842-2420 and the Internal Review Board as directed by Ochsner Medical Center IRB rules and regulations. Furthermore, after the first 25 patients have completed PET 2, review of adverse events and unanticipated problems will be reviewed by a safety monitoring committee comprised of 3 cardiologists who are not involved with study.
