Résumé
Direct oral anticoagulants (DOACs) are replacing warfarin for stroke prevention in patients with atrial fibrillation (AF). To assess the effectiveness and safety of concomitant treatment with antiplatelet-DOAC compared to antiplatelet-warfarin in patients with acute coronary syndrome (ACS) and AF. Retrospective propensity score-matched cohort study using United States-based commercial healthcare database from January 2016 to June 2019. New-users of antiplatelet-DOAC and antiplatelet-warfarin who initiated the combined therapy within 30 days following incident ACS diagnosis. Primary study outcomes were recurrent cardiovascular diseases (CVD) (ie, a composite of stroke and myocardial infarction) and major bleeding events identified via discharge diagnoses. We controlled for potential confounders via propensity score matching (PSM). We generated marginal hazard ratios (HRs) via Cox proportional hazards regression using a robust variance estimator while adjusting for calendar time. After PSM, a total of 2,472 persons were included (1,236 users of antiplatelet-DOAC and 1,236 users of antiplatelet-warfarin). The use of antiplatelet-DOAC (vs. antiplatelet-warfarin) was associated with a reduced rate of recurrent CVD (adjusted HR 0.72, 95% confidence interval [CI], 0.56-0.92) and major bleeding events (adjusted HR, 0.49, 95% CI 0.33-0.72). Residual confounding. In real-world data of AF patients with concurrent ACS, the use of antiplatelet-DOAC following ACS diagnosis was associated with a lower rate of recurrent CVD and major bleeding events compared with antiplatelet-warfarin. These findings highlight a potential promising role for DOACs in patients with ACS and AF requiring combined antiplatelet therapy.

BACKGROUND
Direct oral anticoagulants (DOACs) are replacing warfarin for stroke prevention in patients with atrial fibrillation (AF).
OBJECTIVE
To assess the effectiveness and safety of concomitant treatment with antiplatelet-DOAC compared to antiplatelet-warfarin in patients with acute coronary syndrome (ACS) and AF.
DESIGN
Retrospective propensity score-matched cohort study using United States-based commercial healthcare database from January 2016 to June 2019.
PARTICIPANTS
New-users of antiplatelet-DOAC and antiplatelet-warfarin who initiated the combined therapy within 30 days following incident ACS diagnosis.
MEASUREMENTS
Primary study outcomes were recurrent cardiovascular diseases (CVD) (ie, a composite of stroke and myocardial infarction) and major bleeding events identified via discharge diagnoses. We controlled for potential confounders via propensity score matching (PSM). We generated marginal hazard ratios (HRs) via Cox proportional hazards regression using a robust variance estimator while adjusting for calendar time.
RESULTS
After PSM, a total of 2,472 persons were included (1,236 users of antiplatelet-DOAC and 1,236 users of antiplatelet-warfarin). The use of antiplatelet-DOAC (vs. antiplatelet-warfarin) was associated with a reduced rate of recurrent CVD (adjusted HR 0.72, 95% confidence interval [CI], 0.56-0.92) and major bleeding events (adjusted HR, 0.49, 95% CI 0.33-0.72).
LIMITATIONS
Residual confounding.
CONCLUSIONS
In real-world data of AF patients with concurrent ACS, the use of antiplatelet-DOAC following ACS diagnosis was associated with a lower rate of recurrent CVD and major bleeding events compared with antiplatelet-warfarin. These findings highlight a potential promising role for DOACs in patients with ACS and AF requiring combined antiplatelet therapy.
