ABSTRACT

OBJECTIVES - The aim of this study was to compare ticagrelor monotherapy with dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stents.

 

BACKGROUND - The role of abbreviated DAPT followed by an oral P2Y12 inhibitor after PCI remains uncertain.

 

METHODS - Two randomized trials, including 14,628 patients undergoing PCI, comparing ticagrelor monotherapy with standard DAPT on centrally adjudicated endpoints were identified, and individual patient data were analyzed using 1-step fixed-effect models. The protocol was registered in PROSPERO (CRD42019143120). The primary outcomes were the composite of Bleeding Academic Research Consortium type 3 or 5 bleeding tested for superiority and, if met, the composite of all-cause death, myocardial infarction, or stroke at 1 year, tested for noninferiority against a margin of 1.25 on a hazard ratio (HR) scale.

 

RESULTS - Bleeding Academic Research Consortium type 3 or 5 bleeding occurred in fewer patients with ticagrelor than DAPT (0.9% vs. 1.7%, respectively; HR: 0.56; 95% confidence interval [CI]: 0.41 to 0.75; p < 0.001). The composite of all-cause death, myocardial infarction, or stroke occurred in 231 patients (3.2%) with ticagrelor and in 254 patients (3.5%) with DAPT (HR: 0.92; 95% CI: 0.76 to 1.10; p < 0.001 for noninferiority). Ticagrelor was associated with lower risk for all-cause (HR: 0.71; 95% CI: 0.52 to 0.96; p = 0.027) and cardiovascular (HR: 0.68; 95% CI: 0.47 to 0.99; p = 0.044) mortality. Rates of myocardial infarction (2.01% vs. 2.05%; p = 0.88), stent thrombosis (0.29% vs. 0.38%; p = 0.32), and stroke (0.47% vs. 0.36%; p = 0.30) were similar.

 

CONCLUSIONS - Ticagrelor monotherapy was associated with a lower risk for major bleeding compared with standard DAPT, without a concomitant increase in ischemic events.
