Optimal timing of initiation of oral P2Y12 receptor antagonist therapy in patients with non ST elevation acute coronary syndromes. Lessons learnt from the ACCOAST trial
The optimal time point of the initiation of P2Y12 antagonist therapy in patients with non ST elevation acute coronary syndromes (NTSE ACS) is still a matter of debate. European guidelines recommend P2Y12 as soon as possible after first medical contact. However, the only trial which compared the two strategies did not demonstrate any benefit of pre treatment with prasugrel before angiography compared to starting therapy after angiography and just prior to percutaneous coronary intervention (PCI) This paper summarizes the results of pharmacodynamic and previous studies, and gives recommendations for the initiation of P2Y12 antagonist therapy in NSTE ACS in different clinical situations.
