LIMITATIONS DURING PCI
• Peri-procedural thrombotic events.
• More and more complex coronary lesions (increased thrombotic
risk).
• A high proportion of patients are not optimally treated
• Increased proportion of patients with high bleeding risk (risk of
suboptimal ATT).

PERI-PROCEDURAL THROMBOTIC EVENTS
• 6,591 patients undergoing PCI for ACS in the ACUITY & HORIZONS-AMI trials.
• Intra-procedural thrombotic events in 7.7%.

ADVANTAGES OF I.V. ANTIPLATELET DRUGS IN PCI
• More potent anti-platelet effect.
• Quicker effect.
• Not dependent on patient intake.
• Not dependent on gastro-intestinal
function.
• More homogeneous effect.

“Despite these important considerations, there are several clinical situations where cangrelor could have a major
role. First, because cangrelor is administered intravenously and has rapid onset, it could offer particular
advantages in the STEMI primary PCI setting, especially in patients at high risk, in those experiencing nausea and
vomiting, or in those who are intubated or in cardiogenic shock. There is little opportunity for pretreatment in this
setting and there is invariably a delay to optimum platelet inhibition with even the most effective oral agents. A
randomised trial of cangrelor versus placebo on top of optimum dual oral antiplatelet therapy, including either
ticagrelor or prasugrel, would help solidify its role in this setting. Second, because patients with high-risk non-
STEMI (GRACE score >140) preferentially benefit from early intervention, cangrelor, with its rapid onset and
offset, might offer an advantage in this population. Third, in centres where pretreatment is not routine clinical
practice, cangrelor will probably become a preferred option. Fourth, cangrelor is an attractive option in patients
with high-risk anatomic or clinical features undergoing same-sitting or ad hoc elective PCI for stable coronary
artery disease. There is little opportunity to benefit from preloading in these patients and, somewhat surprisingly,
neither ticagrelor nor prasugrel has been formally studied in this large group of patients”.

SWITCHING FROM ORAL AGENTS TO CANGRELOR
Expert Consensus Recommendations on Switching
Bridging from oral to intravenous P2Y12 inhibitors
• For both cardiac and noncardiac surgery, if withdrawal of P2Y12 inhibiting therapy is needed, clopidogrel and
ticagrelor should be discontinued for 5 days and prasugrel for 7 days.

CONCLUSIONS
• The use of IIb/IIIa inhibitors should be restricted to bail-out or
procedural complications (intra-procedural thrombotic events).
• Cangrelor prevents peri-procedural thrombotic events both in
patients with ACS and stable CAD.
• Lesion complexity plays a key role for selecting patients candidates
to receive cangrelor.
• Other indications of cangrelor include bridging therapy for surgery
after coronary stenting.
