BACKGROUND: Out-of-Hospital Cardiac Arrest (OHCA) and mild therapeutic hypothermia (MTH) have been linked to increased risk of Stent Thrombosis (ST) in comatose survivors who undergo percutaneous coronary intervention (PCI). In this sense, there is no formal recommendation about which antiplatelet regimen should be used in patients with acute coronary syndromes (ACS) after OHCA. AIMS: To compare the incidence of probable/definite ST and bleeding events between ticagrelor and clopidogrel, in patients with ACS under MTH after an OHCA. METHODS AND RESULTS: From January 2010 to August 2016, 144 patients underwent MTH after an OHCA. Overall, 114 had an ACS (79%) and 98 (67,3%) were treated with primary PCI and stent implantation. Among them, 61 (62,2%) were treated with clopidogrel, and 32 (32,6%) with ticagrelor. During hospitalization, the incidence of probable or definite ST was significantly higher in patients receiving clopidogrel compared to ticagrelor (11,4% vs. 0%; p: 0.04), and no significant differences in any (28,6% vs. 25%; p: 0.645) or major bleeding (BARC 3 or 5) (11,4% vs. 12,5%; p: 0.685) were found. Hospital mortality did not differ between groups (26,2% vs. 25%; p: 0.862). CONCLUSIONS: In this study, as compared to clopidogrel, ticagrelor was associated with a lower rate of ST, without differences in haemorrhagic events in patients with OHCA for an ACS under MTH. Similarly to other settings, ticagrelor might be a valid alternative to clopidogrel in these patients.
