The European Society of Cardiology (ESC) guideline for myocardial revascularisation recommends the use of glycoprotein IIb/IIIa-inhibitors in bail-out situations (i.e., intra-procedure thrombus formation, slow flow, threatened vessel closure) during elective PCI, and in NSTE-ACS patients with evidence of high intracoronary thrombus burden. Currently, the ESC guideline discourages the upstream use of glycoprotein IIb/IIIa-inhibitors (Neumann, F-J et al).
In 2010, NICE recommended that a glycoprotein IIb/IIIa inhibitor (e.g., abciximab, eptfibatide or tirofiban) is considered as an adjunct to percutaneous coronary intervention (PCI) for all patients with diabetes undergoing elective PCI, and for those patients undergoing complex procedures (for example, multi-vessel PCI, insertion of multiple stents, vein graft PCI or PCI for bifurcation lesions).
Eptifibatide is a glycoprotein (GP) IIb/IIIa inhibitor. It inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor and other adhesive ligands to the glycoprotein (GP) IIb/IIIa receptors. The efficacy is dose- and concentration- dependent.
ESPRIT study explored the benefit of eptifibatide in 2,064 patients undergoing non-urgent PCI with coronary stent implantation. Eptifibatide therapy was shown to significantly reduce the primary endpoint (composite of death, MI, urgent target vessel revascularisation (UTVR) and thrombotic bailout within 48 hours of randomisation). The incidence of the combined endpoint death or myocardial infarction after 48 hours was also significantly lower in the eptifibatide group compared with placebo (O’Shea et al. 2002).
In UK, eptifibatide is licensed for prevention of early myocardial infarction in patients with unstable angina or NSTEMI with the last episode of chest pain occurring within 24 hours and with ECG changes and/or elevated cardiac enzymes.
This guideline specifically looks at the unlicensed use of eptifibatide in bail-out situations or in patients with high thrombus burden during PCI.
