BACKGROUND: Survivors of out-of-hospital cardiac arrest undergoing percutaneous coronary intervention are at high thrombotic and bleeding risk. The type of antiplatelet that should be used in these patients remains controversial.
AIM: To compare the impact of the use of more potent P2Y12 receptor inhibitors on thrombotic and bleeding events with that of clopidogrel in survivors of out-of-hospital cardiac arrest undergoing percutaneous coronary intervention.
METHODS: This was an observational study including consecutive patients treated for out-of-hospital cardiac arrest associated with acute coronary syndrome by percutaneous coronary intervention with stent implantation and dual antiplatelet therapy between January 2007 and December 2017. Baseline characteristics, mortality and in-hospital haemorrhagic and thrombotic events were compared between patients who received clopidogrel and those who received more potent P2Y12 receptor inhibitors.
RESULTS: Among the 359 included patients, 197 received clopidogrel and 162 received ticagrelor or prasugrel. The primary composite endpoint of death, definite stent thrombosis or major bleeding was similar in the two groups (57.4% in the clopidogrel group vs. 53.7% in the new P2Y12 receptor inhibitors group; P=0.49). Fewer haemorrhagic events occurred in the clopidogrel group (21.8% vs. 31.5%; P=0.04), whereas similar rates of definite stent thrombosis were observed (5.1% vs. 6.2%; P=0.65). The use of more potent P2Y12 receptor inhibitors was an independent predictor of major bleeding (odds ratio 2.69, 95% confidence interval 1.37-5.25; P=0.004).
CONCLUSIONS: In this specific population, the use of more potent P2Y12 receptor inhibitors was not associated with a reduced thrombosis rate compared with clopidogrel, but with a higher haemorrhagic risk. Prospective studies should be performed on the optimal antithrombotic therapy in this subset of patients.
