AHA Coronary Artery Revasc Guidelines 2021 Flashcards
significant L main disease preferred approach for revascularization
surgical - improves survival; PCI still better than med therapy in low/med complexity and LM equally suitable
in pt w/ stable IHD, nl EF, and 3v CAD, what is preferred revasc?
surgical - improves survival; PCI survival benefit is uncertain
radial artery vs saphenous vein for CAD revasc second target?
radial - superior patency, reduced cardiac events, improved survival;
make sure you know if and which radial was accessed during cath
best access for PCI for ACS or stable IHD?
radial better than femoral - dec bleeding and vasc complications, ACS w/ radial approach also has reduced mortality;
if doing CABG after cath and are planning radial conduit, make sure you know which arm was accessed
antiplatelets after PCI w/ stable IHD?
short duration of dual antiplatelet - reduces bleeding events; after 1-3 mo, transition to plavix monotherapy
Pt presents w/ STEMI s/p PCI for culprit artery. What to do for nonculprit artery intervention?
Staged perc intervention (while inpt or after DC) for nonculprit - improved outcomes; can be done at initial PCI, but benefit unclear - do if low-complexity and no renal disease.
PCI of nonculprit in cardiogenic shock can be harmful.
Triple vessel CAD and DM - preferred revasc?
surgical; PCI if poor candidate
What scoring system is best used for tx decisions for surgical revasc of CAD?
STS surgical risk score.
SYNTAX score benefit is less clear d/t interobserver variability - more useful for demonstration of complexity for PCI vs CABG decision.
What procedural measurement can help decision making to proceed w/ PCI in pt w/ angina or equivalent when it isn’t otherwise clear from cath?
FFR >0.8 or iFR >0.89 shows NO benefit from PCI
In pt w/ intermediate stenosis of LM artery, what can be used to help define lesion severity?
IVUS
STEMI and ischemic symptoms decision making?
WHEN did symptoms happen: < or > 12 hrs?
<12 hrs - PCI feasible? Proceed.
<12 hrs - PCI not feasible & LARGE AREA AT RISK? CABG
>12 hrs - <24 hrs? PCI (2a)
>24 hrs w/ total occlusion w/o sx or severe ischemia - NO PCI
ASSOCIATED ISSUES?
>12 hrs - cardiogenic shock or HF? revasc (PCI pref if feasible)
>12 hrs - ongoing ischemia, HF, VF/VT? primary PCI
Failed PCI in STEMI pt w/o ischemia or large area of myocardium; or w/ poor targets - NO emergency CABG.
In conclusion… revasc if <24, shock, ischemia, or unstable rhythm.
STEMI pt s/p PCI of infarct artery. Timing of CABG for complex multivessel non-infarct disease?
elective - reduce risk of cardiac events
Management for NSTE-ACS?
Shock? Angina? VF/VT? -> immediate revasc
GRACE >140? = high risk -> early revasc w/in 24 hrs
Initially stabilized w/ int/low risk of clinical event? - revasc before DC.
Shouldn’t DC these pts.
Revasc algorithm in pts w/ SIHD?
Refractory angina (eg requiring lots of nitro)? revasc (CABG best outcomes in intermed f/u)
LM? CABG
Multivessel? CABG (especially if low EF - benefit >10 yrs)
What SYNTAX score seems to confer CABG survival benefit over PCI for multivessel CAD?
SYNTAX 33
Pt w/ previous CABG with OPEN LIMA to LAD needs repeat revascularization. What approach is recommended (2a)?
percutaneous - open LIMA to LAD increases risk of redo sternotomy; PCI has lower stroke and mortality rate
Pt w/ multivessel CAD is amenable to either PCI or CABG, but cannot take DAPT (access, tolerance, adherence, etc). What do you do?
CABG
A patient w/ CAD is undergoing NON-cardiac surgery. They do not have LM disease, and CAD is not complex. What do you offer?
Do NOT recommend routine coronary revascularization - no benefit.
ISCHEMIA-CKD randomized trial result?
Randomized cath revasc +/- GDMT in stable pt w/ moderate CKD vs conservative mgmt.
Initial invasive strategy showed NO benefit over conservative.
IE In asx ptx w/ stable CAD and CKD, routine angio and revasc not needed.
STILL should revasc STEMI and high-risk NSTE-ACS as long as measures are taken to reduce risk of AKI; low-risk NSTE-ACS should have risk/benefit analysis.
Pt presents w/ VF/VT or cardiac arrest d/t CAD. What should be done?
Revascularization.
In pt CAD and SCAR-RELATED sustained monomorphic VT, there is NO benefit from revascularization as the sole purpose of preventing recurrent VT
