Outcome of urgent and elective percutaneous coronary interventions after pharmacologic reperfusion with tenecteplase combined with unfractionated heparin, enoxaparin, or abciximab.
OBJECTIVES: The aim of this study was to evaluate percutaneous coronary intervention (PCI) in the Assessment of the Safety and Efficacy of New Thrombolytic Regimens (ASSENT-3) trial. BACKGROUND: In the ASSENT-3 trial, co-therapy with abciximab (ABC) or enoxaparin (ENOX) reduced ischemic complications after ST-elevation acute myocardial infarction treated with tenecteplase when compared with unfractionated heparin (UFH). The effect of these new co-therapies on the results of PCI is unknown. METHODS: Clinical outcomes in patients who received co-therapy with ABC, ENOX, or UFH and subsequently underwent an elective (n = 1,064) or urgent (n = 716) PCI in the ASSENT-3 trial were compared. RESULTS: No significant differences in clinical end points were observed in patients who underwent an elective PCI. A non-significant trend toward fewer in-hospital myocardial re-infarctions was seen with ABC and ENOX when compared with UFH (0.5% vs. 0.6% vs. 1.5%, respectively). The incidence of bleeding complications was similar in the three treatment arms. Significantly fewer ABC- and ENOX-treated patients needed urgent PCI compared with UFH (9.1% vs. 11.9% vs. 14.3%; p
