European practice patterns for antiplatelet management in NSTE-ACS patients: Results from the REal-world ADoption survey focus on Acute antiPlatelet Treatment (READAPT) survey

Abstract

BackgroundThe 2020 European Society of Cardiology (ESC) guidelines for the diagnosis and management of patients with non-ST elevation-acute coronary syndrome (NSTE-ACS) recommend early invasive coronary angiography in high-risk patients and no routine pre-treatment with oral P2Y12 receptor inhibitor in NSTE-ACS patients prior to defining coronary anatomy. ObjectiveTo assess the implementation of this recommendation in the real-life setting. MethodsA web-survey in 17 European countries collected physician profiles and their perceptions of the diagnosis, medical and invasive management of NSTE-ACS patients at their hospital. A sample size of at least 1100 responders permitted the estimation of proportions with a precision of at least ±3.0%. ResultsAmong the 3024 targeted participants, 1154 provided valid feedback defined as a 50% response rate of answers to the survey questions. Overall, >60% of the participants declared full implementation of the guidelines at their institution. The time delay from admission to coronary angiography and PCI was reported to be <24 h in over 75% of the hospitals while pre-treatment was intended in >50% of NSTE-ACS patients. Ad-hoc percutaneous coronary intervention (PCI) was performed in >70% of the cases while intravenous platelet inhibition was rarely used (<10%). Between countries differences in practice patterns for antiplatelet management for NSTE-ACS were observed, suggesting heterogeneous implementation of the guidelines. ConclusionsThis survey indicates that the implementation of 2020 NSTE-ACS guidelines on early invasive management and pre-treatment is heterogeneous, potentially due by local logistical constraints.
