Background: Glycoprotein IIb/IIIa inhibitors (GPI) are still used in patients with ST-segment elevation myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention (PCI), although discussion about its clinical benefit is ongoing. Methods: GPI use was analyzed in this subanalysis of the POPular Genetics trial, which randomized STEMI patients to CYP2C19 genotype-guided treatment (clopidogrel or ticagrelor) or standard treatment with ticagrelor/prasugrel. The composite thrombotic endpoint consisted of cardiovascular death, myocardial infarction (MI), definite stent thrombosis, and stroke at 30 days. The combined bleeding endpoint consisted of Platelet Inhibition and Patient Outcomes (PLATO) major and minor bleeding at 30 days. Univariable and multivariable analyses in addition to a propensity score-matched (PSM) analysis were conducted. Results: In total, 2378 patients, of whom 1033 received GPI and 1345 did not, were included. In multivariable analysis, GPI administration was associated with fewer thrombotic events (hazard ratio [HR] 0.22, 95% confidence interval [CI] 0.09–0.55) and MIs (HR 0.24, 95% CI 0.08–0.73). Furthermore, GPI administration was associated with an increase in bleedings (HR 2.02, 95% CI 1.27–3.19), driven by minor bleedings (HR 2.32, 95% CI 1.43–3.76), without a significant difference in major bleedings (HR 0.69, 95% CI 0.19–2.57). In the PSM analysis, no significant association was found. Conclusion: In STEMI patients undergoing primary PCI, GPI administration was associated with a reduction in thrombotic events at a cost of an increase in (mostly minor) bleedings in multivariable analysis, while propensity score analysis did not show significant associations.
