Prasugrel superior to ticagrelor for ACS patients who underwent PCI: JAMA

Germany: A prespecified subgroup analysis of a randomized clinical trial revealed that among patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI), there was a lesser frequency of all-cause death, myocardial infarction when treated with prasugrel compared with ticagrelor.

The findings of this study are published in the journal JAMA Cardiology. 

Ticagrelor is a platelet inhibitor known to reduce deaths in patients with acute coronary syndrome ACS or a history of myocardial infarction (MI). It is unclear whether ticagrelor or prasugrel hydrochloride is superior for patients with ACS treated with PCI. J. J. Coughlan, Deutsches Herzzentrum München, Technische Universität München, Munich, Germany, and colleagues aimed to assess the safety and efficacy of ticagrelor vs prasugrel for patients with ACS treated with PCI.

The study was a prespecified analysis performed of a post-randomization subgroup of 3377 patients who presented with ACS and were treated with PCI in the investigator-initiated, multicenter study conducted from September 1, 2013, to February 28, 2018. Statistical analysis was performed from September 1, 2020, to January 30, 2021. Analysis was performed according to the intention-to-treat principle. Patients were randomly assigned to a ticagrelor-based or prasugrel-based strategy. This analysis focused on the subgroup of patients who underwent PCI that was formed after randomization. The primary endpoint was a composite consisting of all-cause death, myocardial infarction, or stroke at 12 months. The safety endpoint was Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding.
