<jats:p>Cangrelor is the only intravenous P2Y12 inhibitor available. Safety, efficacy, and transitioning from cangrelor to oral P2Y12 inhibitors were recorded in patients with acute coronary syndrome (ACS). The ARCANGELO study aims to assess the safety of cangrelor on bleeding and the effects of the transition to oral P2Y12 inhibitors in a real-world setting according to the European Medical Agency’s requirement.</jats:p>

<jats:title>Methods and results</jats:title>
<jats:p>Adult patients with ACS undergoing percutaneous coronary intervention (PCI) receiving cangrelor were included in the study. Patients were followed for 30 days. Incidence of bleeding events, major adverse cardiac events, and transition strategy to oral P2Y12 were recorded. Among 1004 ACS patients undergoing PCI, 995 (99.1%) were eligible for the analysis; 597 (60.0%) of them had ST-segment elevation myocardial infarction. A total of 925 (93.1%) patients underwent PCI by radial catheter access, and 972 (97.2%) received drug-eluting stents. All eligible patients received bolus and cangrelor infusion between 2 and 4 h in 95% of the cases. A total of 730 patients (73.4%) received ticagrelor, 127 (12.8%) prasugrel, and 138 (13.9%) clopidogrel as transition therapy. Bleeding, according to Bleeding Academic Research Consortium (BARC) criteria, within 30 days post-PCI occurred in 5.2% of patients (95% confidence interval: 3.9–6.8%); 0.5% experienced a moderate (BARC 3), and all others mild (BARC 1–2) bleeding events. Major adverse cardiac events occurred in 14 (1.4%) patients, principally all-cause mortality (n = 6 patients) and myocardial infarction (n = 7 patients).</jats:p>

<jats:title>Conclusion</jats:title>
<jats:p>The use of cangrelor in ACS patients undergoing PCI and the transition strategy to P2Y12 inhibitors are confirmed as safe and effective in daily practice.</jats:p>
