Prior MI or trop positive ACS
DM on oral meds or insulin
CKD (CrCl < 60)
Previous stent thrombosis
Current smoker
> /3 stents
Long lesion > 60 mm total stent
Complex lesion (bifurcation with 2 stents, chronic occlusion)
Lt main or proximal LAD
Multivessel PCI
Risk Factors for Bleeding
OAC + DAPT
> 75
Frailty
Hgb < 110
CRF (CrCl < 40)
BW < 60 kg
Hospitalization for bleed < 1 yr
Previous stroke / ICB
Regular need for NSAID or Prednisone
Duration of DAPT in Patients with ACS (STEMI or NSTEMI) who Undergo PCI
DAPT for 1 year
Preferred DAPT in Patients with ACS (STEMI or NSTEMI) who Undergo PCI
ASA 81 mg once daily +Ticagrelor 90 mg BID or Prasugrel 10 mg once daily
preferred over Clopidogrel 75 mg once daily
What do you reassess at 1 year in Patients with ACS (STEMI or NSTEMI) who Undergo PCI on DAPT
At 1 year, determine bleeding risk
Recommendations at 1 year for patients with ACS (STEMI or NSTEMI) who Undergo PCI on DAPT with low bleeding risk
Continue DAPT for up to 3 years
ASA 81 mg once daily +Ticagrelor 60 mg BID or
Clopidogrel 75 mg once daily2
Recommendations at 1 year for patients with ACS (STEMI or NSTEMI) who Undergo PCI on DAPT with high bleeding risk
SAPT
ASA 81 mg once daily or
Clopidogrel 75 mg once daily
Duration of DAPT in Patients who Undergo Elective PCI Not at high risk of bleeding
DAPT for 6 months
ASA + clopidogrel
Duration of DAPT in Patients who Undergo Elective PCI at high risk of bleeding
DAPT for 1 month if BMS,
or 3 months if DES
THEN
SAPT
ASA 81 mg daily or
Clopidogrel 75 mg daily
Duration of DAPT in Patients who Undergo Elective PCI with High-risk clinical or angiographic features for thrombotic cardiovascular events,
and not at high risk of bleeding
Extend DAPT up to 3 years
ASA 81 mg daily + Clopidogrel 75 mg daily
Interrupting DAPT for Non-Cardiac Surgery: BMS
recommend delaying surgery for at least 1 month after PC
Continue ASA perioperatively
withhold clopidogrel and ticagrelor for 5-7 days pre-operatively
withold prasugrel for 7-10 days pre-operatively
Interrupting DAPT for Non-Cardiac Surgery: DES
recommend delaying surgery
for at least 3 months after PCI
Continue ASA perioperatively
withhold clopidogrel and ticagrelor for 5-7 days pre-operatively
withold prasugrel for 7-10 days pre-operatively
When to restart DAPT in PCI after non cardiac surgery
restart maintenance dose after surgery, as soon as it is deemed safe by the surgeon
Management of DAPT for Elective or Semi-urgent CABG Surgery after ACS (minimum vs. ideal)
continuation of ASA
minimum interruption of ticagrelor and clopidogrel for 48-72 hours before CABG ideal interruption period of 5 days before elective CABG
minimum interruption of prasugrel for 5 days before CABG and recommend an ideal interruption period of 7 days before elective CABG
Switching from clopidogrel to ticagrelor
Loading dose: 180 mg
Maintenance dose: 90 mg twice daily
Timing: regardless of the timing of the last clopidogrel dose
