Background: To date, there are no real-world studies comparing cangrelor to glycoprotein IIb/IIIa inhibitors (GPI) during percutaneous coronary intervention (PCI). Thus, we performed this study to evaluate the safety and effectiveness of cangrelor compared to GPI during PCI.
Methods: We identified patients who underwent PCI at our institution who received either cangrelor or GPI during PCI. Patients already on GPI or cangrelor prior to PCI or who received both cangrelor and GPI were excluded. Baseline demographics and clinical outcomes were extracted. Major bleeding is defined as a composite of major hematoma >4 cm, hematocrit drop >15, and gastrointestinal bleeding.
Results: A total of 2072 patients received adjunctive antiplatelet therapy during PCI (cangrelor [n=478]; GPI [n=1594]). Patients' mean age was 61±12 years. Most (66%) presented with acute coronary syndrome. Patients who received cangrelor were older and had a higher percentage of acute coronary syndrome and lower baseline hematocrit in comparison with patients who received GPI. Procedural success was achieved in 94% of patients, with no difference between groups. Major bleeding events (1.7% vs. 5.1%, P=.001), any vascular complication rates, and hospital length of stay were significantly lower in the cangrelor group. In-hospital ischemic events did not differ between groups. On regression analysis, patients on cangrelor were noted to have significantly lower major bleeding events (OR 0.23; 95% CI, 0.09-0.59).
Conclusions: Balancing ischemic and bleeding risks with adjunctive antiplatelet drugs is of prime importance during PCI. Our real-world analysis shows that cangrelor is safe and effective when compared to GPI during PCI.
