Prevalence of in-hospital P2Y12 inhibitors use and switching. Switching occurred mostly in the form of changing from clopidogrel to ticagrelor (50.3%) or prasugrel (40.1%).

Multivariate analysis of predictive factors of switching to a novel P2Y12 inhibitor in patients who were initially treated with clopidogrel. CABG, Coronary artery bypass grafting; COPD, chronic obstructive pulmonary disease; CrCl, creatinine clearance; RR, relative risk; STEMI, ST-elevation myocardial infarction; TIA, transient ischemic attack.

Patients analyzed at follow-up. Propensity-matched pairs were created among 524 patients with in-hospital switching to a novel P2Y12 inhibitor, 633 clopidogrel only, and 460 prasugrel or ticagrelor only treated patients.

Percentage standardized differences in patients’ characteristics before and after propensity score matching who either switched from clopidogrel to ticagrelor/prasugrel, or were only ticagrelor/prasugrel treated (A) and either switched from clopidogrel to ticagrelor/prasugrel or were only clopidogrel treated (B). MI, myocardial infarction; FMC, first medical contact; CrCl, creatinine clearance; COPD, chronic obstructive pulmonary disease.
