摘要
Background: In the COMPASS trial, the combination of acetylsalicylic acid (ASA) plus 2.5 mg rivaroxaban twice daily (dual-pathway inhibition, DPI) has been shown to be superior to ASA monotherapy for the reduction in ischemic major adverse cardiovascular events (MACEs, i.e., cardiovascular death, stroke, or myocardial infarction). Methods: The international XATOA registry (Xarelto plus Acetylsalicylic acid: Treatment patterns and Outcomes in patients with Atherosclerosis) is a prospective post-approval registry that investigates the cardiovascular outcomes of patients taking ASA plus 2.5 mg rivaroxaban. The aim of this pre-specified analysis was to determine the net clinical outcome (NCO), i.e., a combination of MACEs and bleeding events, of DPI in patients from daily clinical practice. Results: Among the 5615 patients, the presence of multiple risk factors resulted in an increase in the total risk of experiencing an NCO event, e.g., from 1.27% (one risk factor) to 2.18% (two risk factors) and 4.07% (three or more risk factors), respectively, with ischemic MACE representing the primary driver of bleeding complications. Conclusions: In the real-world XATOA registry, the annual rate of NCO events was low and numerically similar to those seen in the treatment group in the randomized COMPASS trial.
