OUR MISSION: TO REDUCE THE BURDEN OF CARDIOVASCULAR DISEASE
Prof. Jean-Philippe Collet (FR)Initiation of P2Y12 inhibitors soon after the diagnosis of NSTE-ACS has been recommended for many years and was derived from pivotal clinical studies validating the efficacy of clopidogrel therapy, a pro-drug with a slow onset of action(1,2). The concept of pretreatment has been first revisited by the meta-analysis of Bellemain et al showing no survival benefit for clopidogrel pretreatment in 37,000 patients undergoing PCI but a slight excess of major bleeding and little impact on ischemic outcomes(3). A randomized comparison of pretreatment with prasugrel compared with initiation after diagnostic angiography, but before PCI, has demonstrated no reduction in key ischaemic events at 7 days(4). The question is now whether time has come to change the guidelines and our clinical practice.The ACCOAST study compared pre-treatment with prasugrel 30mg and a further 30mg prior to PCI with a regimen of prasugrel 60mg prior to PCI after diagnostic angiography among 4033 patients with NSTEMI. By 7 days, patients randomized to the pretreatment arm experienced no reduction in the risk of cardiovascular death, recurrent myocardial infarction, stroke, urgent revascularization and bailout use of glycoprotein IIb/IIIa inhibition (hazard ratio 1.02, 95% C.I. 0.84-1.25, p=0.81), with no benefits emerging by 30 days.However, bleeding events using the TIMI major bleeding criteria, were significantly increased among patients randomized to the pretreatment arm by 7 days (pretreatment 2.6% versus no-pretreatment: 1.4%, hazard ratio: 1.90, 95% C.I. 1.19-3.02, p=0.006).In particular, there were significantly more major and life-threatening bleeding complications not related to coronary artery bypass graft (CABG) surgery in the pretreatment group.ACCOAST randomized patients of the real life of whom 20% had a GRACE score of 140 or more and who had angiography within a median time delay from symptom onset of 12 hours. Practical impacts are therefore of importance. First, the use of new P2Y12 inhibitors in NSTE-ACS may be postponed to the time of the decision about PCI, to avoid overtreatment in patients who may need CABG surgery or medical treatment who do not need such high platelet inhibition. Second, can the ACCOAST results be applied to other P2Y12 inhibitors, such as clopidogrel and ticagrelor? The negative study results for prasugrel pretreatment raised a general question on the benefits achieved by pretreatment with new oral platelet inhibitors, even if there is a single and successful study with ticagrelor whereby treatment was given systematically as pretreatment(5). Conclusion: A realistic and pragmatic approach would be to make the decision to initiate P2Y12 receptor inhibitor prior to defining the revascularization strategy according to the intended agent and expected delay to obtaining angiography. In patients with a short delay (< 24—48 hours) from admission to angiography, pretreatment should be avoided; in patients with a delay from admission to angiography of > 48 hours, pretreatment with either clopidogrel (on the basis of old data) or ticagrelor (without data) may be considered.
