BACKGROUND: The ACCEPT registry was designed with the purpose of identifying the incorporation of evidence in the treatment of acute coronary syndrome. The objective of this analysis is to describe the antithrombotic therapy adopted in the treatment of patients undergoing primary percutaneous coronary intervention (PCI) in centers participating in this national project. METHODS: We evaluated the subgroup of patients undergoing primary PCI, measuring variables related to demographic characteristics as well as the prescription of evidence-based interventions, focusing on in-hospital and 6-month antithrombotic therapy. RESULTS: From August 2010 to December 2011, 588 patients with mean age of 61.8 ± 12.3 years were studied, 75.2% were males and 24.1% had diabetes mellitus. The dual antiplatelet therapy most commonly given was the combination of acetylsalicylic acid (ASA) and clopidogrel. Unfractionated heparin and enoxaparin were the predominant anticoagulation therapy during and after the procedure, respectively. When compared to in-hospital prescription, a significant decrease in the rate of patients using ASA (98.3% vs 93.9%; P < 0.0001) and clopidogrel (95.4% vs 67.7%; P < 0.0001) was observed at the 6-month follow-up. CONCLUSIONS: In the ACCEPT registry, a high percentage of in-hospital prescription of dual antiplatelet therapy was observed in patients undergoing primary PCI, notably the combination of ASA and clopidogrel, with an inadvertent reduction of clopidogrel at the 6-month follow-up, encouraging efforts to use evidence-based practices.
