ABSTRACT
BACKGROUND AND PURPOSE:
The purpose of this study was to evaluate the association between different antiplatelet therapy regimens and the functional outcomes and bleeding complications among mild-to-moderate ischaemic stroke patients based on real-world data.METHODS:
We used data from the SEACOAST trial (Safety and efficacy of aspirin-clopidogrel in acute noncardiogenic minor ischaemic stroke) to analyse the data of patients with mild-to-moderate stroke within 72 h after onset who were treated with aspirin or clopidogrel alone or a combination of clopidogrel and aspirin from September 2019 to November 2021. Propensity score matching (PSM) was used to balance the differences between groups. We performed an analysis to evaluate the association of different antiplatelet regimens and 90-day disability, which was defined as a modified Rankin Scale score ≥2, as well as disability ascribed to index or recurrent stroke by the local investigator. In terms of safety, we then compared the bleeding events between the two groups.RESULTS:
A total of 2822 mild-to-moderate ischaemic stroke patients were treated with either clopidogrel plus aspirin (n = 1726, 61.2%) or aspirin/clopidogrel (n = 1096, 38.8%). Of 1726 patients in the dual antiplatelet group, 1350 (78.5%) received less than or equal to 30 days of combined therapy. At 90 days, 433 (15.3%) patients were disabled. Patients who received combined therapy had a lower overall disability rate (13.7% versus 17.9%; OR 0.78 (0.6-1.01); P = 0.064). However, investigators found that index stroke was the reason for significantly fewer patients in the dual antiplatelet group having disability (8.4% versus 12%; OR, 0.72 (0.52-0.98); P = 0.038). There was no statistically significant difference in the incidence of moderate to severe bleeding complications between the dual and mono antiplatelet drug regimens (0.4% versus 0.2%; HR 1.5 (0.25, 8.98); P = 0.657).CONCLUSION:
Aspirin plus clopidogrel was associated with a reduction in the incidence of disability attributed to index stroke. There was no statistically significant difference in the incidence of moderate to severe bleeding complications between the two antiplatelet drug regimens. TRIAL REGISTRATION NUMBER ChiCTR1900025214.
