Although P2Y12 receptor blockers have become a standard, adjunctive therapy in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI), the optimal regimen has not been established. We performed a prospective, open-label, randomized study to investigate the effect of cangrelor administration on platelet function and inflammation in patients with primary PCI (PPCI). Twenty-two patients were randomized to receive either cangrelor and ticagrelor or ticagrelor alone (standard group) before PPCI. Platelet reactivity was evaluated at baseline (before PCI), 10 min and the end of the procedure. At baseline, there was no significant difference in platelet reactivity between both groups, whereas platelets were significantly inhibited at 10 min after initiating cangrelor vs. standard (adenosine-diphosphate-induced aggregation 102.2 ± 24.88 vs. 333.4 ± 63.3, P < 0.05 and thrombin-receptor-activating-peptide-induced aggregation 285.8 ± 86.1 vs. 624.8 ± 106.0, P < 0.05). Lower platelet aggregation in the cangrelor group persisted but the difference was reduced by the end of the procedure. Circulating inflammatory cells, pro-inflammatory cytokines, total elastase, and surrogates of neutrophil extracellular traps (total elastase-myeloperoxidase complexes) were significantly lower in the cangrelor compared to the standard therapy group at 6 h after randomization. There was a trend towards reduction in cardiac damage in the cangrelor group as reflected by the changes in late gadolinium enhancement between 48 h and 3 months after STEMI. Early administration of cangrelor in STEMI patients was associated with more effective platelet inhibition during PPCI and significantly dampened the deleterious inflammatory response compared to standard therapy (NCT03043274).
