Impact of Baseline Bleeding Risk on Efficacy and Safety of Ticagrelor versus Clopidogrel in Chinese Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention
Among the 20,816 eligible PCI patients who were included in this study, there were 1578 and 779 patients in the clopidogrel and
ticagrelor groups, respectively, after PSM, their clinical parameters were well matched. Patients receiving ticagrelor showed comparable NACE risk compared with those treated by clopidogrel (5.3% vs. 5.1%, P = 0.842). Furthermore, ticagrelor might reduce the MACCE risk in patients with low bleeding risk but increase MACCE in patients with moderate‑to‑high bleeding potential (ticagrelor vs. clopidogrel, low bleeding risk: 2.5% vs. 4.9%, P = 0.022; moderate‑to‑high bleeding risk: 4.8% vs. 3.0%, P = 0.225; interaction P = 0.021), with vast differences in all bleeding (low bleeding risk: 1.5% vs. 0.8%, P = 0.210; moderate‑to‑high bleeding risk: 4.8% vs. 3.0%, P = 0.002; interaction P = 0.296).
