How to win thisdebate
• A COMMON PROBLEM
• 40-50%of patientswith STEMI haveMVdisease
• Nature of non-culprit disease: a mixedbag of challenges!
![Page 18: Multivessel Diseasein STEMI: FIXTHECULPRITand ......CTO intervention after STEMI. Blinded evaluation of endpoints. • Patients Patients with STEMI treated with pPCI and with a non-infarct](https://reader033.vdocuments.us/reader033/viewer/2022060100/60ae744c81c76d1da602cde0/html5/thumbnails/18.jpg)
How to win thisdebate
• Me: Fix the culprit IRAwith a perfectresult
Leave the rest for thoughtfulapproach—LATER!
• Tim: Just fix them all after you fixthe infarct artery…..Don’t be lazy!
![Page 19: Multivessel Diseasein STEMI: FIXTHECULPRITand ......CTO intervention after STEMI. Blinded evaluation of endpoints. • Patients Patients with STEMI treated with pPCI and with a non-infarct](https://reader033.vdocuments.us/reader033/viewer/2022060100/60ae744c81c76d1da602cde0/html5/thumbnails/19.jpg)
NON-IRA: What we don’t know
• Fix it during infarct
• Stent before discharge…..?FFR
• Stent in a few weeks…..? FFR
• Get a stress test and go fromthere
• Fix only if symptoms
![Page 20: Multivessel Diseasein STEMI: FIXTHECULPRITand ......CTO intervention after STEMI. Blinded evaluation of endpoints. • Patients Patients with STEMI treated with pPCI and with a non-infarct](https://reader033.vdocuments.us/reader033/viewer/2022060100/60ae744c81c76d1da602cde0/html5/thumbnails/20.jpg)
Why NOTdo all the blockages?
Benefits
• Avoid risk of second procedure• Decrease infarct size by increasing
collateral flow?• Reduce recurrent MI?• Reduce length of stay?• Reduce recurrent ischemia?
![Page 21: Multivessel Diseasein STEMI: FIXTHECULPRITand ......CTO intervention after STEMI. Blinded evaluation of endpoints. • Patients Patients with STEMI treated with pPCI and with a non-infarct](https://reader033.vdocuments.us/reader033/viewer/2022060100/60ae744c81c76d1da602cde0/html5/thumbnails/21.jpg)
Why NOTdo all the blockages?
• Increase infarct size
–Non-IRAPCI related no-reflow, ST
• Contrast induced nephropathy
• Increase cost with no clinical benefit
• Do they all need another PCI?
• Risks

Tim is tricky: Watch out for him!
• He will quote meta-analysesthat areflawed and confounded by includingobservation registriesor RCT’swithsmall trials!
• He will show multiple anecdotalexamplesto try and prove hispoint!

J Am Coll Cardiol 2016;67:1235-1250
2013 Recommendation 2015 Focused Update
Recommendation
Comment
Class III: Harm Class IIb
PCI should not be
performed in a
noninfarct artery at the
time of primary PCI in
patients with STEMI who
are hemodynamically
stable. (LOE:B)
PCI of a noninfarct artery
may be considered in
selected patients with
STEMI and multivessel
disease who are
hemodynamically stable,
either at the time of
primary PCI or as a
planned staged
procedure . (LOE: B-R)
Modified
recommendation
(changed class from III:
Harm to IIb and
expanded time frame in
which multivessel PCI
could be performed).

EXPLORETrial Outcome
- Early CTO-PCI :
- not associated with higher LVEFand lower LVEDV @ 4 months

CTO-PCI in the LAD was associated with higher LVEF@ 4 months

STEMI
Significant N-IRA lesion
Will the patient be better off/worse offif it is treated with PCI?

Final thoughtsWhat I have to concede to Tim:
meta of 7 RCT’sshowsno increase inCIN with MVPCI same settingorbefore DC
What Tim has to concede to me:
If Danami 3 isright and 31%of 50-90%lesionsare FFRnegative…..we willbe doinga lot of unnecessary stenting!

Final thoughts
• No one trial will likely settle thisdebate
• BEA DOCTOR..No-Reflow in IRA, don’t ’play with fire in non-IRA!
• At least we have some data to makechoices and not end up in Guideline-Jail
• More powerful studieson the way
