Introduction: We aimed to compare the outcomes of ACS (acute coronary syndrome) patients undergoing in-hospital PCI (percutaneous coronary intervention) treated with prasugrel versus ticagrelor. Methods: Among 7,233 patients enrolled to the ACSIS (Acute Coronary Syndrome Israeli Survey) between 2010 and 2018, we identified 1126 eligible patients treated with prasugrel and 817 with ticagrelor. Comparison between the groups was preformed separately in ST-elevation myocardial infarction (STEMI) patients, propensity score matched (PSM) STEMI patients, and non-ST-elevation ACS (NSTE-ACS) patients. Results: In-hospital complication rates, including rates of stent thrombosis, were not significantly different between groups. In PSM STEMI patients, 30-day re-hospitalization rate (p <0.05), 30-day MACE (the composite of death, MI, stroke and urgent revascularization; p=0.006), and 1-year mortality rates (p = 0.08) were higher in the ticagrelor group compared to the prasugrel group; In NSTE-ACS patients, outcomes were not associated with drug choice. In cox regression analysis applied on the entire cohort, prasugrel was associated with lower 1-year mortality in STEMI patient but not in NSTE-ACS patients (p for interaction 0.03). Conclusions: Compared to ticagrelor, prasugrel was associated with superior clinical outcomes in STEMI patients, but not in NSTE-ACS patients.
