Insights

Cangrelor showed lower odds of favorable outcomes in emergent carotid artery stenting compared to glycoprotein IIb/IIIa inhibitors, but improved stent patency versus aspirin. Further research is needed.

Area of Science:

  • Neuroendovascular treatment
  • Cardiovascular pharmacology

Background:

  • Periprocedural antiplatelet therapy is crucial for emergent carotid artery stenting (eCAS) during endovascular treatment (EVT) for stroke.
  • Assessing cangrelor against glycoprotein IIb/IIIa (GPIIb/IIIa) inhibitors and aspirin monotherapy is vital for optimizing risk-benefit profiles.

Purpose of the Study:

  • To compare the safety and efficacy of cangrelor versus GPIIb/IIIa inhibitors or aspirin monotherapy in patients undergoing eCAS for anterior circulation tandem lesions.

Main Methods:

  • Retrospective analysis of 384 patients from the Endovascular Treatment in Ischemic Stroke (ETIS) registry (January 2015 - June 2023).
  • Patients received periprocedural treatment with cangrelor, GPIIb/IIIa inhibitors, or aspirin monotherapy.
  • Primary outcome: functional outcome at 90 days (modified Rankin Scale); Secondary outcomes: recanalization, hemorrhagic transformation, stent patency.

Main Results:

  • Cangrelor was associated with poorer functional outcomes compared to GPIIb/IIIa inhibitors (aOR 0.48).
  • Cangrelor improved carotid stent patency at day 1 versus aspirin (aOR 4.00) but showed no significant clinical outcome differences.
  • GPIIb/IIIa inhibitors demonstrated higher odds of functional independence than aspirin (aOR 2.56).

Conclusions:

  • Cangrelor may be associated with a trend towards lower odds of favorable clinical outcomes compared to GPIIb/IIIa inhibitors in eCAS.
  • While cangrelor improved stent patency, findings require cautious interpretation due to potential selection bias.
  • Further research is warranted to validate these findings in emergent stroke treatment.
