Downstream cangrelor versus upstream ticagrelor in patients with ST-segment elevation myocardial infarction: A propensity score-matched analysis.

BACKGROUND

Pretreatment with a P2Y

METHODS

STEMI patients undergoing PCI from October 2019 to June 2023 were included. The primary outcome was the composite of in-hospital major adverse cardiovascular events (MACE). Secondary outcomes included individual components of the primary outcome and in-hospital major bleeding. Univariable and multivariable regression analyses were performed in unmatched and propensity-matched cohorts.

RESULTS

Of 6086 patients enrolled in the prospective CAST registry, 761 were included: 383 (50.3 %) received downstream cangrelor and 378 (49.7 %) upstream ticagrelor. In the matched population, no between-group differences were observed in MACE (odds ratio [OR] 1.30; 95 % confidence interval [CI] 0.79-2.17; P 0.308), all-cause death (OR 1.91; 95 % CI 0.87-4.54; P 0.124), myocardial infarction (OR 2.64; 95 % CI 0.76-12.14; P 0.154), stent thrombosis (OR 0.38; 95 % CI 0.06-1.80; P 0.255), unplanned repeat revascularization (OR 1.22; 95 % CI 0.32-4.98; P 0.766) and major bleeding (OR 0.98; 95 % CI 0.50-1.93; P 0.955). Cardiogenic shock and bailout administration of glycoprotein IIb/IIIa inhibitors were independent predictors of MACE, while radial access showed an inverse association.

CONCLUSIONS

In P2Y
