ABSTRACT
BACKGROUND:
The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI.METHODS:
In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization.RESULTS:
Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446).CONCLUSIONS:
Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.
