Background: Out of hospital cardiac arrest (OHCA) patients requiring percutaneous coronary intervention (PCI) are at higher risk of both stent thrombosis and bleeding. The use of aggressive antiplatelet therapy could lead to a higher risk of bleeding in these patients. Indeed, data on glycoprotein IIb/IIIa inhibitor (GPi) use in this specific indication is scarce.Aim: We sought to evaluate the benefit and safety of GPi use in OHCA patients requiring PCI.Methods and Results: Between January 2007 and December 2017, we retrospectively included all consecutive patients treated with PCI for an OHCA from cardiac cause. Clinical, procedural data and in-hospital outcomes were collected. Three hundred and eighty-five patients were included. GPi were administrated in 41.3% of cases (159 patients). Patients who received GPi were younger, had less prior PCI, more often a TIMI 0 or 1 flow before PCI and thromboaspiration use. There were no differences regarding in-hospital definite stent thrombosis among the two groups (11.9% in the GPi group vs 7.1% in the non-GPi group, p = 0.10) or in-hospital mortality (48.6% vs 49.3%, p = 0.68). The incidence of any bleeding (33.3% vs. 19.6%; p = 0.002), and major bleeding (BARC 3-5) (21.9% vs. 16.8%; p = 0.007) was significantly higher in patients receiving GPi. Indeed, using multivariate analysis, GPi use was predictor of major bleeding (OR: 1.81; 95% CI: 1.06-3.08; p = 0.03).Conclusions: In patients treated with PCI for OHCA from cardiac cause, GPi use was associated with an increased risk of major bleeding events, without difference on in-hospital stent thrombosis or death.

Data is scarce on hemorrhagic and thrombotic complications in patients with ST-elevation myocardial infarction (STEMI) associated with out-of-hospital cardiac arrest (OHCA). This is a monocentric, retrospective study conducted from January 2012 to December 2017 in a tertiary university hospital, which serves as a cardiac arrest center for a large urban area. Over the study period, all consecutive patients who were treated with stent implantation for STEMI with or without OHCA were included. Baseline characteristics, treatments, hemorrhagic and thrombotic events were compared between STEMI patients with and without OHCA. Univariate and multivariate analysis were performed in order to identify predictors of 30-day mortality, occurrence of major bleeding (MB), and early stent thrombosis (ST). A total of 549 patients treated for STEMI without OHCA and 146 patients for STEMI with OHCA were included. The incidence of definite ST and MB after coronary angioplasty was significantly higher in patients with OHCA (2.6% vs. 7.5%, p = 0.004 and 3.3% vs. 19.2%, p < 0.001, respectively). Independent predictors of MB in OHCA patients were anticoagulation therapy (HR = 3.11, 95%CI [1.22–7.98], p = 0.02) and the use of glycoprotein IIb/IIIa inhibitors (HR = 4.16, 95%CI [1.61–10.79], p = 0.003). Independent predictors of mortality in OHCA patients were age (HR = 1.05, 95%CI [1.02–1.09], p = 0.004) and ST (HR = 5.62, 95%CI [1.61–19.65], p = 0.007, with a protective effect of new anti-P2Y12 treatments (HR = 0.20, 95%CI [0.08-0.46], p < 0.001). Patients treated for STEMI associated with OHCA are at higher-risk of ST and MB than those who did not experience cardiac arrest. In this subset of patients, prospective studies are needed to better evaluate the balance of thrombosis and hemorrhage. [ABSTRACT FROM AUTHOR]
