Background: De-escalation of P2Y12 inhibitor may occur for various clinical reasons in patients with acute myocardial infarction (AMI). We aimed to assess the characteristics and outcomes of patients who underwent a de-escalation strategy in real-world clinical practice. Methods and Results: We studied 2604 AMI patients initially treated with prasugrel using the Japan Acute Myocardial Infarction Registry (JAMIR) database. Of these, 110 (4%) were discharged on clopidogrel [de-escalation group; switching 4 days after admission (median)] and the remaining 2494 continued prasugrel at discharge (continuation group). The de-escalation group had higher incidence of heart failure or history of cerebrovascular disease, and were more likely to receive mechanical circulatory support, and oral anticoagulation than the continuation group. During mean follow-up of 309±133 days post-discharge, no significant differences were observed in ischemic events (2.2% vs. 2.8%, p = 0.74) or major bleeding (1.1% vs. 1.6%, p = 0.72) between the de-escalation and continuation groups. Conclusions: Although, patients with de-escalation from prasugrel to clopidogrel had higher bleeding risk profile than those continued on prasugrel, post discharge ischemic and bleeding events were similar between patients with and without de-escalation. De-escalation strategy may be an option for AMI patients with high risk for bleeding.
