Analisi della recente evoluzione temporale dell’impiego della terapia antitrombotica nei pazienti con sindrome coronarica acuta sottoposti ad angioplastica coronarica in Italia: confronto dei registri EYESHOT e SCOPE

BACKGROUND: Few data exist on temporal evolution of antithrombotic agent use in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) in Italy. We sought to compare data from the most recent prospective, multicenter, nationwide registries conducted in Italy, namely EYESHOT and SCOPE. METHODS: EYESHOT enrolled 2585 consecutive ACS patients, both ST-segment elevation myocardial infarction (STEMI) and non-ST elevation ACS (NSTE-ACS), admitted to 203 Italian coronary care units over a 3-week period (2-22 Dec 2013 and 27 Jan-16 Feb 2014). Among patients enrolled in EYESHOT, 1755 (67.9%) underwent PCI (52.6% with STEMI and 47.4% with NSTE-ACS). In the SCOPE registry, a total of 1363 patients undergoing PCI were enrolled over 3 months (15 Feb-15 Apr 2016) in 39 Italian cath lab centers at medium to high PCI volume: 331 (24.3%) with a diagnosis of STEMI and 1032 (75.7%) with a diagnosis of NSTE-ACS. RESULTS: Over 2 years, the use of clopidogrel in the cath lab significantly decreased (from 11% to 8% in STEMI; p=0.06 and from 9% to 5% in NSTE-ACS; p=0.0002), while the administration of ticagrelor dramatically increased (from 14% to 37%; p<0.0001 in STEMI and from 7% to 44%; p<0.0001 in NSTE-ACS). At discharge, a significant decrease in the use of clopidogrel (from 32% to 21% in STEMI; p=0.02, and from 47% to 24% in NSTE-ACS; p<0.0001) and a concomitant increase in the novel P2Y12 receptor inhibitor prescription occurred, particularly among NSTE-ACS patients (from 8% to 14% for prasugrel; p=0.002 and from 43% to 58% for ticagrelor; p=0.03). CONCLUSIONS: From the present analysis on ACS patients undergoing PCI enrolled in EYESHOT and SCOPE registries, a significant increase in the use of novel P2Y12 receptor inhibitors was observed, both at the time of PCI and at discharge.
