Introduction and methods

The combination of 2.5 mg rivaroxaban and 100 mg aspirin compared with aspirin alone resulted in a 24% reduction of the primary outcome, a composite end point of CV death, stroke, or MI, in patients with chronic coronary artery disease (CAD) or peripheral artery disease (PAD), as shown in the COMPASS trial [1-3]. The combination is now approved in >100 countries for prevention of CV death, stroke and MI in patients with CAD or PAD.

In this study, the effect of the combination of rivaroxaban and aspirin compared with aspirin alone was examined on the outcome of mortality, by cause and in risk subgroups.

COMPASS was a multicenter, international trial that randomized 18,278 CAD and PAD patients to the combination of 2.5 mg rivaroxaban twice daily and 100 mg aspirin once daily, 5 mg rivaroxaban twice daily or 100 mg aspirin once daily. Median follow-up was 23 months (IQR: 16-30 months).

Main results


The combination of rivaroxaban and aspirin reduced all-cause mortality and CV mortality, but not non-CV mortality, compared to aspirin alone in CAD and PAD patients in the COMPASS trial. Consistent reductions were seen for causes of CV mortality with the combination compared to aspirin alone and there were also consistent relative risk reductions across risk subgroups.
