Abstract
The benefits of potent antithrombotic therapy usually come at the expense of a higher risk of bleeding. The efficacy and safety of ticagrelor in elderly East Asian populations remains debated due to the concerns about the imbalance of ischemic and bleeding risks. This study aimed to compare the impact of clopidogrel with ticagrelor on clinical outcomes in East Asian patients aged ≥75 years with acute coronary syndrome (ACS) using data from an institutional registry. We assessed the treatment effect of ticagrelor versus clopidogrel based on propensity scores and multivariate Cox proportional hazards models. A total of 2775 ACS patients were included, of which 235 (8.5%) were treated with ticagrelor. The primary efficacy outcome occurred in 11.9% of patients treated with ticagrelor versus 8.8% treated with clopidogrel. There was no significant association between treatment with ticagrelor and a lower risk of the primary efficacy outcome (p = .156). However, the incidences of all-cause death (hazard ratio [HR] 1.69, 95% confidence interval [CI] 1.02 to 2.79) and major bleeding (adjusted HR 2.20, 95% CI 1.06 to 4.56) were significantly higher in patients treated with ticagrelor than clopidogrel. In elderly patients with ACS from East Asia, the efficacy of clopidogrel was comparable to ticagrelor, while ticagrelor is associated with an increased risk of mortality and major bleeding.
