Purpose
To compare the effect of ticagrelor with clopidogrel in reducing the risk of ischemic cardiovascular events in patients with late or very late stent thrombosis (LST/VLST) after primary percutaneous coronary intervention (PCI).
Methods
A total of 4538 patients with acute coronary syndrome were screened for angiographically determined LST/VLST. Two hundred and forty-one patients were included in the analysis and grouped according to ticagrelor (n = 81) or clopidogrel (n = 160) at discharge. The clinical outcome was major adverse cardiovascular events (MACE) defined as death, myocardial infarction (MI), ischemic stroke, and revascularization during the 1-yr follow-up period.
Results
After propensity score matching, 65 pairs were generated. The incidence of MACE was significantly lower in the ticagrelor group compared with the clopidogrel group (9.3% vs. 21.5%, log-rank p = 0.048). However, no difference was observed in event rates of death, MI, ischemic stroke, and revascularization between the ticagrelor group and the clopidogrel group.
Conclusion
Following successful primary PCI, patients with LST/VLST who received ticagrelor had fewer ischemic cardiovascular events at 1-yr follow-up, compared with those who received clopidogrel.
